Different used industrial freezing equipment
Food freezing is one of the most important things in the food industry. The food industries use this method to preserve different types of foods and increase their shelf life. But one freezing method is equipment that cannot be used for freezing all types of food. Different types of foods require different freezing technologies. Since there is a wide range of freezing equipment available, it can be confusing at times to choose the right one for you.
There are different types of equipment which work for different foods and products.
- Air Blast Freezer
Air blast freezer is also commonly known as cold storage freezer and it is the oldest type of freezers. It is a very simple method and involves very low investment. Air blast freezer is suitable for freezing large and unprocessed products but the thing which should be kept in mind is that it is a slow method of freezing. One advantage of air blast freezer is that it can be used for freezing different types of products.
- Box Freezer
Box freezers are also known as cartoon freezers. In these box freezers, the products which are packed are sorted, transported and then stored in shelves in a storage which has cold blasts of air. These boxes are then left there for a long time. Box freezers have an automated mechanism and they require less manpower. The main disadvantage of box freezers is that they cannot be used for all types of products.
- Contact Freezers
One more type of freezing equipment is contact freezers. The main method of heat transfer used by contact freezers is conduction. In contact freezers, the food comes in contact with a cold surface and it is then frozen.
- Cryogenic Freezers
Cryogenic freezers use different gases which are liquefiable such as nitrogen or carbon dioxide. These gases are used by cryogenic freezers for producing vapours and these vapours freeze the products.
- Plate Freezers
Another equipment used for freezing is plate freezers. These are usually used for freezing flat products such as fish fillets, pastries and beef patties. They can also be used to freeze products which are irregular shaped such as cauliflower and broccoli. The main benefit of plate freezers is that the food is frozen quickly in them and they are very easy to install as well as easy to clean.
- Belt Freezers
Belt freezers are of different types which include single, multi or spiral belt freezers. They use a vertical airflow and then the cold air is forced through a layer. The cold air is then distributed over the belt area. Few products that can be frozen in the belt freezers are meat patties, fish cakes and filets. These foods can be frozen or unpackaged.
These were the various freezing equipment commonly available in the market. However, there are some other equipment too which can be used for different products. If you want to buy freezing equipment, then you can check the types and uses of these equipment online and make the decision according to your needs.
