Opening the door to improved temperature control in food processing

April 2018

Hygiene, temperature control and process efficiency are all watch words in the food processing and food distribution industries. Guy Windle, Area Sales Manager of sara LBS, says high speed roller shutter doors can be essential in achieving all of these.

Go into any food processing or distribution plant and the first thing you notice will probably be the drop in temperature as you enter. Food keeps freshest and retains its nutritional qualities best in cooler environments, while lower temperatures also help to reduce bacterial activity and therefore maintain hygiene standards.

Not surprisingly there are strict regulations in most countries surrounding temperature and hygiene control in food handling areas. Typically, thermometers are located at strategic places around food sites, notably near doors and access points, which are read and logged automatically. In many cases these will alert managers if temperatures go out of tolerance for extended periods of time.

Food companies therefore need to keep their production areas - possibly even the entire building - cooled, which can lead to significant refrigeration and air conditioning costs. Obviously, insulating the walls and ceilings will help maintain the desired temperature, while high speed automatic doors will minimise the thermal fluctuations as people, trolleys and vehicles enter and exit the temperature-controlled spaces.

Food processing and distribution companies that need to keep large spaces cool and hygienic, often also face the dilemma of requiring access for large vehicles. These entryways can be fitted with doors to help maintain the internal temperature while the design of the doors can be optimised to meet the particular needs of their duty.

sara LBS offers several industrial door and loading bay solutions which offer high levels of insulation. These tend to be fitted with high speed automatic drives so that the amount of time they are open is minimised. Further, they can also be designed for good hygiene regimes through the use of stainless steel and other materials able to withstand regular washdowns and steam cleaning and by designing out dirt traps.

Amongst food companies, sara LBS’s Sprint range of high speed curtain doors is a popular choice, possibly because they offer the fastest operating speeds on the market. As a whole the Sprint range is suitable for most indoor and some outdoor industrial applications, while specialist versions are available for food industry applications and even for certified cleanrooms.

The sara LBS Sprint range offers market leading opening speeds (up to 2.2 m/s) and closing speeds (1.0m/s), yet through controlled acceleration and deceleration profiles minimises wear and tear over time. Other optional features much appreciated in the food industry include battery backup, a curtain tensioning system, a door line photocell, dual opening heights, electrical safety contact edge, fall down protection, and a combined cable guide and hygiene cover. Sprint doors can be set up to integrate with a traffic light control system, particularly useful in installations where large vehicles are present.

In addition to the Sprint range, sara LBS offers specialised sliding doors for refrigeration and freezer applications. Typically, this would be lined with 100mm to 150mm of insulation to reduce heat transfer as much as possible. Such doors are generally powered and automated so that operatives cannot leave them open for unnecessary periods. The use of timers, presence detectors and temperature sensors ensure optimum operation and safety and enable full data logging of operations for traceability records.

Doors can play a very effective role in maintaining hygiene levels in food facilities, whilst also helping to control energy usage for cooling. sara LBS engineers have a wealth of experience specifying and installing doors in many different environments so can help identify the best door for any given situation.

Should you calculate U-Values for loading bay doors?

April 2018

Loading bays often need to be heated (or cooled), either to protect stored goods or to provide a comfortable working environment, but with large doors open for significant periods of time heating costs can be high. Louise Nurse of loading bay specialists, sara LBS, says it is natural for senior management to want to control this cost, but a practical rather than theoretical approach must be used.

In most working environments heating energy demand is relatively easy to calculate, based of the internal volume of the workspace and the ability of the walls to retain the heat, expressed as their U-value. There is a bit more detail in that the ceiling, doors and windows will almost certainly have different U-values than the walls, so they have to be calculated separately.

As a general rule doors are usually closed, so their thermal insulating effect is nearly fully utilised. However, when a door is open, its effective U-value drops to zero.

In loading bays the giant loading doors have to be open a lot of the time, so it is inevitable that heat will escape. There is a cost associated with this heat loss, which management will naturally want to control, which often leads to questions about the U-value of the loading bay doors.

There are three major issues that arise when assessing the thermal performance of a loading bay door:

1: Open and shut – Operational loading bays spend a lot of time with their main door open. Self-evidently, goods cannot be loaded or unloaded unless there is a truck in the bay, i.e. the door has to be open much of the time.

2: Door construction – Most loading bay doors are of the roller shutter or sectional overhead type, chosen because they provide a wide, clear opening that is unobstructed from all directions, easy to operate (often powered) and not overly prone to damage. However, such doors are made up of a number of parts, and while the panels and profiles can be insulated to a specified U-value, there will inevitably be joints between the parts where the insulating capabilities are reduced.

3: Door mounting – The door, whatever its type, will be mounted in a frame. Inevitably there will be a gap between the door and its frame, and typically this will be quite a significant gap to ensure free movement of the door in the frame. But it will also allow heat to escape. It is possible to fit insulating brushes or seals within the frame, but their effectiveness and longevity are limited.

Theoretically it is possible to calculate the overall U-value of a closed door by summating the individual U-values of the door panels, the inter-panels joints and the gap between the door and frame. It is also possible in theory to do overall heat retention calculations that incorporate a value for the amount of time the door is open.

However, experience shows that such calculations rarely reflect actual performance when measured by taking multiple temperature readings over a period of time in the loading bay. Probably the biggest reason for this is not so much the U-values, but the difficulty in accurately predicting the amount of time the door is open over a given shift, coupled with the near-impossibility of predicting the outside temperature (plus wind speed and other chill factors) at the times when the door is open.

This is easy to understand at a theoretical level, but it can lead to a range of different reactions. Logistics managers, driven by a desire to handle goods quickly, efficiently and safely, tend to accept heat loss through open loading bay doors as a ‘necessary evil’. However, their colleagues in the finance department tend see the heat loss as an avoidable expense. To an accountant it makes sense to minimise heat loss by closing the loading bay doors as much as possible and making sure they have a good U-value.

At sara LBS we are often asked for U-value calculations and are happy to help. However, the first thing we do is point out the practical difficulties and suggest that a long term survey is needed.

As a general rule, we recommend a pragmatic approach. Take comprehensive readings at different times of the year (and at night if 24-hour working is required) and build up a thermal profile of the loading bay in general and main door in particular. There are then several approaches to consider.

At the door opening, there are a number of technologies that could be useful, such as insulated doors, a secondary curtain door (often insulated and usually with high speed actuation), an air curtain or local heater. Another option that is often very effective is to fit an inflatable loading pod to the outside of the loading bay; when a lorry parks in the bay, the pod inflates to seal against its sides and top (although its underside remains open). Sometimes a simple side wall to break the wind and/or porch for rain protection will have a significant effect.

A practical alternative solution we’ve encountered has been to heat the rear and centre of the loading bay and accept that the area around the door will be a cold spot. Working practices can then be developed that minimise the amount of time operatives spend in the cooler areas.

In conclusion we can say that while it is understandable that managers want to control their energy spend, sometimes an overly theoretical approach will be counterproductive. The U-value of a loading bay door can provide a guide to overall heat retention, but it would be inappropriate to rely on this figure too much. It is far better to take a practical approach with real world measurements and real-world solutions.
