How to improve efficiency in your Blast Freezing

There are so many benefits to using blast freezers within the food industry.

Apart from quickly chilling cooked food and preserving its flavour, colour, texture and nutritional value, blast freezers can double food’s natural expectancy and eliminate the chances of harmful bacteria growth. Using them correctly is key to achieving the best results.

Here’s how to best care for them to improve their efficiency.

The right size

Blast Freezers come in so many different sizes to suit all needs. From Mega Cold Stores and Refrigerated Containers to Portable Blast Freezers and Mini Blasts.

Choosing the right Blast Freezer is key to not overspending on energy bills. Think ahead about the amount of food or product you will be regularly chilling to make your decision. If you are thinking of buying but are not sure which size to go for, you can always rent the equipment first to understand what suits you best.

At CRS, we sell and rent equipment to offer you the solution that best covers your demands.

Keeping the door closed

Try to put everything into the Blast Freezer at once before the cycle starts. Apart from being more energy friendly, you will be avoiding the risk of the other food being subjected to the warm air.

Minimising the risk of damaging the food being chilled is one of the benefits. By keeping the door closed once the cycle starts, you will also be ensuring that there’s an even, all-around flow of air to allow all food to freeze uniformly.

General maintenance

The maintenance of your Blast Freezer is essential, not just from a safety point of view but also to prolong the service life of the equipment. Making sure you carry out regular check-up tasks will help you always keep the units in safe operating condition.

Some tips for cold storage maintenance:

Regular cleaning

The whole unit needs to be kept clean. Making sure your condenser coils are spotless will ensure the unit chills appropriately, hitting the mark in terms of optimal energy efficiency.

Similarly, the door gaskets will need to be clean to provide a tight seal and avoid warm air coming through .

Check for temperature fluctuations

If you spot something strange in the way your unit operates, check this with an engineer as soon as possible to avoid potential issues with food contamination or food wastage.

Keeping up-to-date with the technical appointments

Blast Chillers need to be checked-up regularly to ensure the correct functioning of the units. Make sure you don’t miss your maintenance appointments as these are a critical preventive measure in keeping your cold storage containers working correctly.

At CRS, we operate a 24-hour emergency call out service to all units that are on hire and under service contracts. We also offer maintenance contracts on purchased equipment.
