Blast Freezer, Automatic Grade : Manual

Industrial Refrigeration Pvt. Ltd.(IRPL) offers Blast Freezer systems to the food industry.

Blast chilling is a method of cooling food quickly to a low temperature that is relatively safe from bacterial growth. Bacteria multiply fastest between +8 °C (46 °F) and +68 °C (154 °F). By reducing the temperature of cooked food from +70 °C (158 °F) to +3 °C (37 °F) or below within 90 minutes, the food is rendered safe for storage and later consumption. This method of preserving food is commonly used in food catering and, recently, in the preparation of 'instant' foods, as it ensures the safety and the quality of the food product.

A blast freezer may also be known as a shock freezer. Such freezers are intended to rapidly bring the temperature of foods down, freezing them extremely quickly. These specialized freezers are used in the frozen food industry for everything from ice cream to television dinners, and they are also utilized in some commercial kitchens for specialty tasks.

When food is frozen, the water inside it crystallizes. If freezing takes place at relatively warm temperatures, the ice crystals which form will be large. In a blast freezer, the extremely cold temperature promotes very rapid freezing, which creates small ice crystals. The smaller the crystals, the less damage to the food, as large crystals can rupture cells. Once the food has been frozen in a blast freezer, it can be moved to a more conventional freezer for storage, as long as the freezer stays cold enough to keep the food frozen.

Applications:-
Freezing into blocks is an effective economical method of preserving, handling transporting and storing perishable products. Horizontal Plate Freezer in one easy operation, ideal for freezing fish, offal’s, fruit puree, fish fillets, shrimp and vegetables. 
Products are simply placed into horizontal pockets between the aluminum freezing plates. After freezing, the blocks can be unloaded manually or mechanically onto pallets or a conveyor system and within minutes the whole processing cycle can begin again.
