Hygienic FRP Doors for Infant formula Facilities

Infant Formula

Baby formula or infant formula is primarily used as a substitute for human milk. Other uses include ‘follow up’ products as a dietary supplement for older infants, and special formulations for specific nutritional needs or to overcome allergies e.g. Soya based milks for lactose intolerant infants.

The Process

The milk powder process involves the gentle removal of water at the lowest possible cost under stringent hygiene conditions while retaining all the desirable natural properties of the milk – colour, flavour, solubility, nutritional value. Whole (full cream) milk contains, typically, about 87% water and skim milk contains about 91% water. During milk powder manufacture, this water is removed by boiling the milk under reduced pressure at low temperature in a process known as evaporation. The resulting concentrated milk is then sprayed in a fine mist into hot air to remove further moisture and so give a powder.

Hygienic Considerations

To fulfil today’s increasing demand for baby formula to meet physical, chemical and bacteriological requirements, there is an increasing focus on the design of manufacturing facilities to meet the strictest hygiene standards.

Codex, which is jointly run by the UN Food and Agriculture Organisation (FAO) and the World Health Organisation (WHO), sets international food safety and quality standards. In their code of hygienic practice for milk products they state that production facilities should be designed and constructed to ensure minimum contamination and to allow easy cleaning, maintenance and disinfection.

Every component of a Dortek door has been designed to meet the strict focus on hygiene in infant formula facilities. We are the trusted hygienic door for the top 5 infant formula companies worldwide with a client list which includes Abbott Nutrition, Mead Johnson, Fonterra, Glanbia, Kerry, Danone, Nestle and Wyeth.

Here are the reasons why Dortek FRP doors are the ultimate hygienic solution for infant formula facilities;

  • Maximum Hygiene  Smooth and seamless finish which is easy to clean with no ledges or voids to harbour bacteria.
  • Moulded-In Gel Coat – Every Dortek door has a corrosion resistant finish called a gel coat which is moulded in at the initial step of fabrication.  This leaves it completely sealed and protected.
  • Fiber Reinforced Polyester Composite – Our doors will not rust or corrode unlike steel alternatives.
  • Extreme Strength & Durability – Will not dent, warp, swell, rot or rust. FRP is commonly used in high performance aircraft and boats.
  • Lightweight – 40% lighter than steel doors which require replacement or repairs due to wear on hinges and closers.
  • Maintenance Free – Permanent built in colour which will never require repainting.
  • Heat Resistant – Ability to withstand areas with high humidity or extreme temperatures.
  • Chemical & Water Resistant – Ideally suited to highly corrosive environments including frequent exposure to water and cleaning agents.
  • Fire Resistant – Our hygienic fire rated doors meet over 50 independent tested specifications compliant with worldwide regulations.

Choosing the Right Doors for Food Processing Facilities

Today’s hygiene regulations require buildings used for food and beverage manufacture to meet specific standards in their layout, design and construction. In particular, they should permit good hygiene practices, be easy to clean and disinfect and should protect food against external sources of contamination, such as pests and bacteria.

Choosing a door that’s fit for purpose is an important part of achieving these standards. Door systems play an essential role in preventing cross contamination as well as maintaining correct room temperatures and ensuring optimum operating efficiency. Here we look at some of the key considerations in more detail.

Protection against pests and contaminants

Minimising any potential for contamination is one of the highest priorities in food processing facilities. To minimise bacteria, it is essential that doors are completely seamless and impervious in order to prevent germs building up in any hard to clean gaps or cracks in the doors surface.

Surfaces in food facilities must be cleaned thoroughly and regularly. Doors must have smooth, waterproof surfaces which are easy to clean and disinfect. They also need to be durable enough to withstand impact from traffic and vigorous cleaning procedures, which typically include very hot water, steam and aggressive cleaning chemicals. If doors start to crack, rot or peel this can reveal areas for bacteria to reproduce which will compromise hygiene.

Reducing energy costs

Door selection is also an important factor in keeping the temperature levels balanced in food facilities. Door should enable easy access for goods and people whilst also minimising air exchange. This not only improves the efficiencies of the building itself by lowering refrigeration costs and condensation, but it also improves the quality of the products.

Automated doors can be used in conjunction with air tight doors at the appropriate locations to offer a higher degree of air management control. Sealing and/or automatic doors can prevent air from travelling to areas where it’s not supposed to, improving temperature control and cross contamination.

Increasing safety and productivity

Doors need to be wide enough to allow the easy movement of staff, equipment and vehicles, but also correctly installed so that there are no gaps around the doors or frame. When doors are in frequent use (for example in loading bays) additional measures like automations and self-closing mechanisms may be necessary to increase opening speeds and help minimise pests.

Automatic or fast acting doors can be beneficial for high traffic areas in particular or where open food products are being transferred. Shorter opening times can minimise draughts, dust and contamination whilst also increasing production efficiency and saving energy costs. Furthermore, automated doors help improve staff safety and prevent damage to the door by reducing collisions.

Doors in high traffic areas and those which are likely to have equipment and forklifts passing though should be strong and able to withstand heavy impacts. Preventative maintenance should also be considered for all doors to keep them in peak operating condition and to help prevent costly downtime throughout the facility.

Fire protection and safely segregating spaces

Fire doors are one of the most critical elements of fire protection. They are an important part of compartmentation which helps to slow down the spread of fire and smoke and allow occupants to either escape the building by keeping escape routes clear of smoke and fire, or wait for rescue.

The selection and installation of fire doors which are fire tested and proven compliant by a third party approved organisation is essential. A fire door is much more than just a door leaf. The door leaf, the frame, the hinges, the fittings, the hardware, the glass in the vision panels and the seals are all dependent upon each other, to ensure the effectiveness of the door in a fire. The full door assembly must be fire tested as a combination of all elements together, rather than each component individually.

Fire doors are carefully engineered fire safety devices which should be fitted correctly by experienced installers from a reputable company. A certified fire doorset which is incorrectly installed may provide very little, if any, fire resistance at all. For this reason, specifiers should always use professional installers who are fully trained.

Security and Accessibility 

Along with equipment in the facility, doors are a critical component for Food security, especially in food auditing inspection processes which are typically conducting annually by authorised accredited inspection agents.

Innovative Hygienic Door Solutions

Long-term durability and high performance are achieved by specifying the most suitable door materials. Doors in food facilities will be one of the most frequently used and touched components so longevity, cleanability and durability are crucial factors. When selecting doors, food facilities commonly have four materials to choose from—steel, timber, laminate or hygienic GRP. However, in areas where hygiene is important, there is really no comparison between them. In every aspect, hygienic GRP doors perform much better than their steel or timber counterparts. The construction of steel and timber doors leaves seams and crevices, particularly around vision panels and the top and edges of doors. These harbour bacteria and are difficult to clean, creating contamination risks. Steel doors also oxidise when exposed to regular cleaning regimes, whereas timber/laminate doors warp, rot and decay when exposed to moisture.

Hygienic doors are also better value than its competitors, when lifecycle costs are factored in. Depending on the type of structure, steel doors will often require additional heavy steelwork to reinforce the door opening before installation. In high usage areas, doors are subject to a lot of wear and tear. The surfaces of steel, timber and laminate doors mark very easily and require regular maintenance to ensure hygienic performance is not compromised. Also, should they suffer impact damage, can easily dent, and cannot be repaired in situ.

Hygienic access solutions such as Dortek’s have become the leading solution for food facilities to overcome the limitations of other doors. Hygienic doors comply with all the latest good manufacturing practice (GMP) requirements in the food sector. They have a smooth, seamless construction which is easy to clean and does not harbour bacteria. The inorganic GRP door surface and core is also completely water resistant and does not warp, rust or rot when exposed to disinfectants. Doors can also be supplied and installed with numerous choices of automations, access control and air tight sealing choices to suit each opening. In addition, a huge range of colours are available for both door and frame, ensuring colour matching throughout the facility.

Waterproof Doors

Specifying doors in a leisure centre can be a daunting process particularly around the swimming pool area. The growing demands of hygiene legislation and increasing pressure on leisure facilities to ensure performance match the demands of the environment, mean that there are now more elements to consider than ever before.

Waterproof doors need to be impervious to moisture, lightweight, strong and durable to withstand heavy usage. They also need to be hygienic and aesthetically pleasing.

Our waterproof doors are a timber free, one-piece moulded construction which prevents internal decay to door structures or chemical and biological attacks. Simply put, this means the door will not rust, rot, or warp. They are easy to clean and require minimal maintenance and are also more hygienic than timber or laminate doors. Elements such as steam, chlorine and other chemicals/cleaning agents will not affect the composure of these doors.

Timber and laminate doors are not only potentially weaker than GRP doors, and thus more easily damaged, but can also pose a higher risk, as a knock or chip may invite organic materials (dirt) to enter and fester, inevitably bacteria will reproduce and thrive. These types of door are virtually impossible to keep clean effectively. Timber or laminate doors may be adequate for general office settings but not for areas where cleanliness is of utmost importance. These reasons are why GRP is the material of choice for the modern architects of leisure construction.

We manufacturer an extensive range of waterproof doors for specific areas where moisture levels are high. These include:

  • Swimming pools
  • Changing areas
  • Wet rooms
  • Bathrooms
  • Shower areas
  • Toilet and washroom blocks

Organic vs Hygienic GRP doors: Infection control and best practice in the specification of doors in hygienic settings.

Here at Dortek we are passionate about what we do. With over 50 years of experience in the door manufacturing industry there’s not much we don’t know. Les Blennerhassett, technical director of Dortek, Ireland’s leading suppliers of hygienic doors to the healthcare and pharmaceutical sector, explains the infection control benefits of using Dortek glass reinforced polyester (GRP) over wood and laminate doors in a hospital setting.

Dortek Hygienic GRP Doors

Specifying doors in a hospital setting can be a daunting process. The growing demands of hygiene legislation and increasing pressure on hospitals to ensure performance matches the demands of the environment, means there are now more elements to consider than ever before.

“Traditionally, hospital doors have been painted wood or wooden cored laminate. However, because of increasing standards of hygiene and infection control, GRP is becoming the material of choice for the modern hospital designer, not only for high risk areas such as intensive care, pharmacy cleanrooms and operating theatres, but also for medium risk areas like recovery suites, laboratories and hydrotherapy pools.

GRP is a high technology engineering composite, manufactured from millions of strands of glass fibre and polyester resin. Dortek Hygienic Doors are manufactured in Ireland using a unique closed mould process, creating a strong, uniform product with no seams or joints on the door surface and no holes or crevices within that might harbour bacteria.

While wooden or laminate ‘lick and stick’ doors may be adequate for non-critical areas such as corridors, waiting areas and general office space, in areas where cleanliness is of the utmost importance, organic materials are not suitable. No one would consider using organic materials to make trolleys, benches or operating tables, and yet we still see doors manufactured with timber lippings, frames and vision panel surrounds in widespread use.

In a hospital setting, doors are subject to aggressive use and wear and tear on a regular basis, with trolleys manoeuvred in confined spaces inevitably hitting both the door and its frame. In the past, concerns were purely aesthetic, and repairs could be carried out when areas were closed for major maintenance. However, when surfaces are damaged these days there is an immediate risk to infection control that must be dealt with urgently. Whereas laminate and timber doors might need to be replaced in this instance, GRP doors are much stronger, and can be easily and effectively restored to their original state.

Timber and laminate doors are not only potentially weaker than GRP doors, and thus more easily damaged, but can also pose a higher risk, as a knock or chip may reveal organic materials below where bacteria could reproduce, as well as being virtually impossible both to clean and keep clean effectively. Unlike laminate and timber doors, which can deteriorate quickly once exposed to common cleaning regimes, hygienic GRP doors like those produced by Dortek Ireland are able to tolerate constant cleaning, the prolonged use of disinfectants, chlorine releasing agents and VHP (vaporised hydrogen peroxide).

The international pharmaceutical anti biotechnology industry has already turned its back on timber and laminate doors, replacing them with GRP as standard across many manufacturing facilities. With the standards of cleanliness demanded by such industries, hospital specifiers need to recognise that the downside of infection contamination in a cleanroom far outweighs any reason not to reconsider the decades-old thinking behind conventional hospital hygienic door specification.”

Meet our Project Manager, Andy Lowe

Please tell us a bit about yourself!

I have been in East Yorkshire now for 20 years, I moved up North from Somerset. I’m relatively new at Dortek, I started last September, my background prior to Dortek was very much site-based, working in the M&E sector on all commercial projects. A considerable amount of the work involved office fit-out and pharmaceutical warehouses.

 

What first inspired you into the engineering and architectural industry?

From a young age I always liked drawing, the only subject I was good at when I was at school was art and technology, I went on further to study aspects of design at university. I studied interior and landscape, architectural, which I graduated in with a bachelor honour. 

 

As an apprentice I worked within an architectural practice. From then on I knew I had a passion for construction, it was just finding the right sector within the industry. I’m very interested in the way things are put together. Whether it was playing with Lego as a kid or having a passion for buildings and the environments they sit within. Fulfilling my desire to combine creativity with practicality and problem solving, I couldn’t imagine doing anything else at the time, I knew it was the career choice for me. 

 

What made you want to work for Dortek?

I was looking for a new challenge, a new chapter, everyone has personal goals to reach and I had a good feel for Dortek on my initial interview. I felt Dortek was going to push my career forward to where I was aiming to be and what I wanted to achieve. 

 

In my previous employment, for seven years, I worked away from home so having a perfect balance of site and office working now I’m at Dortek is great. 

 

How has COVID affected your role within Dortek?

I think COVID has been very challenging, especially within the construction industry; health and safety for contractors and everyone working on site is a huge factor. For the first couple of months at the company, I was on site shadowing engineers. Installing doors with face coverings or shields can be difficult at times, I found it was no longer the case of just turning up and starting work anymore, you need to be prepared with the testing procedures prior to arriving and on the day of arrival. 

 

Sites are very busy and can be very populated, working through a pandemic you always needed to use you own personal judgment. However, I strongly believe many contractors have developed new methods for delivering projects and ways to keep people communicating effectively whilst working together on a project. 

 

What do you like about working with Dortek?

It’s a very busy atmosphere working on Dortek’s project management team, which I love. I learnt very quickly that every day can be very different, dealing with numerous clients can be challenging yet extremely exciting and rewarding. As much as this opportunity came as a huge learning curve to me, the help and support I received from everyone within the team has been outstanding. Everyone has taken the time in some way to help me grow within the company. You really couldn’t have asked for better colleagues. 

 

What are your interests outside of work?

My two-year-old son keeps me very much on my toes, I follow rugby league, Hull Kingston rovers especially, so finally being able to take my son this year to a few home games will be a proud moment to share with him. I try to keep as active as possible swimming, mountain biking, and the odd game of 5 a-side-football.

Away from sport, me and my partner seem to be passing ships with her career as a nurse so whenever possible we like to get away from home, spending weekends exploring different places like the coast, Lake District and pretty much anywhere that has a good country pub. A few trips abroad are definitely well overdue, which we hope to make this year.

A guide to crash doors and their benefits

Crash doors, also commonly called impact resistant doors, are used in many applications where there is a need to get between two rooms quickly and easily.

Crash doors have a number of advantages including strength, high operating efficiency, heat conservation, infection prevention and noise pollution. They are specifically designed to offer reliable, safe and durable operation to meet the demands of retail and industrial environments.

Let’s explore each of the benefits these types of doors offer in more detail.

They withstand high traffic and heavy impacts

The most essential feature of a crash door is that they are built to withstand heavy impacts. High traffic areas such as retail environments will have cages, forklifts and other equipment frequently passing through so they need to be strong and able to endure high impacts.

Dortek crash doors are constructed from GRP, which is plastic reinforced by fine fibres made of glass. GRP is known for its high mechanical strength and durability.

Crash doors are designed for heavy duty areas and usually come equipped with door protection which can include polypropylene bumpers. These help to guard against aggressive traffic and prevent damage to the door face.

They support hygiene

Retail, food, manufacturing and commercial kitchen environments all place hygiene as a key priority. Premises should permit good hygiene practices, be easy to clean and disinfect and should offer protection against external sources of contamination, such as pests and bacteria.

The benefit of crash doors is that they’re constructed with a high-density glass fibre reinforced polyester core that prevents water absorption and bacteria. The smooth, hygienic GRP surface is easy to keep clean. They are ideal for wash down areas due to the fact that they will not swell, rot, rust or warp.

These doors are also valuable for pest control as they prevent access from unwanted visitors entering the premises, particularly where there is food.

They help improve operational efficiency and productivity

Large retail stores experience high volumes of traffic every day. Suppliers and employees move around these stores frequently which is why a typical door would be unsuitable to this environment. A crash door is specially designed to increase productivity and to enable smooth and easy access. Doors can also come prepared with kick and push plates as well as hold open devices.

GRP is a naturally insulating material which helps maintain temperature controls. Features like these are very beneficial, especially for areas that are humid or for food or household items that are sensitive to temperature. Crash doors are an economical way to reduce both heat loss and noise pollution in working environments.

Crash doors constructed from GRP are also extremely lightweight and impact resistant with long lasting built-in colour. The outer skin of the door has a gel coat finish which is chemically bonded to the glass fibre. This ensures that the door will never require repainting or refinishing. All these factors give the doors low life cycle costs and means they are often proven to outlive their usage.

The main benefits of Dortek crash doors are:image4

  • Robust Design – a durable, hardwearing construction which is built to last in high traffic applications
  • Hygienic – smooth, easy to clean, non-porous gelcoat finish which does not harbour bacteria and is resistant to water and cleaning chemicals
  • Easy to Operate – lightweight, 180-degree swing hinge system which is user friendly
  • Automatic Self Closing – crash doors will automatically close behind the person using them
  • Cost Effective – helps reduce building energy costs by keeping temperature-controlled zones isolated
  • Efficient – helps improve traffic flow and enable people, forklifts and trolleys to move around buildings quickly
  • Reduces Contamination/Noise – separates areas to help reduce contamination, dust, fumes and noise pollution
  • Pest Control – helps prevent access for pests or birds.

Product Showcase – Hermetic Sealing Sliding Doors

Dortek hermetic sealing sliding doors are specifically designed for use in areas where hygiene and the control of air leakage is critical.

The hermetic door has a unique patented track system which enables it to seal perfectly when closed helping to reduce cross contamination and expensive air handling costs. Air leakage has been tested independently and results up to 400 Pa pressure are available.

Hygienic Flush Finish

The door blade is manufactured from high technology engineered GRP/FRP using a unique closed mould process. This creates a strong, uniform product with no seams or joins on the door surface and no voids, holes or crevices within for bacteria to harbour.

Hermetic Sealing

Dortek hermetic doors have a patented track system, which works in combination with the door’s weight, works with a continuous neoprene gasket to create a perfect seal against the doorframe. This seal has been independently tested and found to be more than 99% effective, leaking less than 0.2m³/hr of clean air with a typical pressure differential of 20 Pa.

Smooth Sliding Action

The doors smooth, controlled, sliding action helps to reduce air disturbance and the consequent movement of airborne micro-organisms. The door cuts through the air causing minimal disturbance, whereas traditional hinged doors can disrupt the airflow in a clean area each time they’re opened.

Intelligent Automation

The intelligent automation senses if an obstruction is present and prevents the door from closing thus eliminating the need for a dirty safety strip. Additional safety is provided by means of a photo cell fitted across the door opening. Our range of automations can be integrated with a range of access control systems including touchless sensors for effortless, hands free operation.

Patented Track System

The unique patented track system is angled at 45 degrees and special indentations allow the bearings to roll down enabling the door using its own weight to seal perfectly against the frame and floor.

Floor Sealing System

A tough neoprene gasket seals perfectly against a level floor without the need for a raised threshold. Guiding and sealing cams are fitted outside the clear opening eliminating the requirements for a floor track, allowing free unrestricted access for wheeled traffic.

X-Ray & Fire Protection

Our hermetic sealing sliding doors can be supplied with up to 60 minutes fire ratings, sound insulation and lead lining.
