With frozen food suppliers under constant pressure to reduce processing costs, BQF(batch quick freezing) have a significant impact on costs saving. The air blast freezer is a kind of BQF freezing machine, it is a type of shock freezer. It is for the purpose of small capacity (generally 400kg - 2.5T/day) freezing. The freezer is widely used to freeze high-value seafood and meat, such as poultry, beef and shrimp. Also available to bakery, pastry, ice cream and etc.

The food materials are loaded in roll-in trolleys, Move the trolleys into the insulation room. Freon system create low temperature freezing surrounding, Strong air flow fans circulate the air to accelerate heat transferring. The lowest inner temperature can reach to -45℃(-49℉). The blast freezer or shock freezer is the necessary equipment for hotel, supermarket, refectory, canteen and small food processing plant.

We can make the various size roll-in trolleys and trays, also provide the solution for blast chiller (temperature range: -15℃(5℉) - -20℃(-4℉)), and deep walk in freezer (min temperature: -60℃(-76℉)).
