What is air blast freezer?

What is air blast freezer?

Simply put, a blast freezer is a freezer that is very cold.

This type of freezer storage rapidly brings down the temperature of (usually) cooked or fresh produce, freezing it very quickly to lock in the taste and nutrition of the food for optimum quality for consumers.

What is the difference between a freezer and a blast freezer?

Blast Chiller vs Freezer
The difference between a freezer and a blast chiller is that a freezer holds food at below freezing temperature while a blast chiller cools food quickly by blowing cold air over the food product and gradually dropping the temperature in the chamber.

What is the temperature of air blast freezer?

Air blast freezers are used to freeze food commodities from a chilled temperature to their desired storage temperature (product dependant) with air temperatures between -35°C and -45°C. Typically, the freezing time varies from 12-48 hours.

How much faster is a blast freezer?

Compared to the 6-12 hours it may take for a normal freezer to freeze food, the much colder temperature in a blast freezer decreases the freezing process to a time of approximately 3 hours.

What are the benefits of a blast freezer?

Bacterial Protection and Control
One of the biggest benefits of blast freezers is that they have the ability to freeze several tons of produce in as little as 24 hours. This super-fast process ensures that bacteria has minimal time to develop and keeps produce fresh in bulk.

Which is a disadvantage of using a blast chiller freezer?

Disadvantages of blast freezing
Small fluctuation in storage temperature can result in defrosting into a large lump. Blast freezers are not appropriate for domestic use. Blast freezers are very expensive.

Can you store food in a blast freezer?

Blast Freezers are most used in hotels, big restaurants, fast-food restaurants, canteens, resorts and catering. They are designed to freeze food and beverages (up to -18°C), allowing you to store processed meat for up to two months and salads and desserts for up to 1 year.

What are the components of blast freezer?

Blast chiller freezer is one kind of the freezers. It is a professional storage tool for storing various foods that need to be frozen. Its refrigeration system consists of 4 essential parts, namely the compressor, condenser, throttling component, and evaporator.

Is blast freezing good?

Safer: The blast freezing process is an excellent way to minimize bacteria growth. Normally, bacteria growth occurs between 4°C (40℉) and 60°C (140℉). Since the freezing occurs so quickly, bacteria don’t have much time to multiply. The food remains free of these microorganisms.

Which gas is used in blast freezing?
