Principle and characteristics of fruit and vegetable freezer

The evaporating temperature of the refrigeration system of the fruit and vegetable quick-freezing machine is -35°C to achieve rapid freezing. At this time, the discharge temperature is -18°C, while similar products from other manufacturers need an evaporating temperature of -40°C to achieve this effect. In this way, the refrigeration system can save about 25% of energy consumption.

Equipment working characteristics

1. High freezing efficiency, wide variety of frozen products

2. Realize the continuous monomer quick freezing of food.

3. Adopt mechanical air cooling device, low energy consumption.

4. High-pressure blower and mesh belt adopt frequency conversion adjustment and time indicator to realize precise processing.

5. Adopt continuous cleaning and drying device, clean and hygienic.

6. Fast at -32°C temperature

7. There are many types of frozen products. In addition to being suitable for continuous freezing of fruits and vegetables, it can also be used for continuous and rapid freezing of seafood, such as scallops, shrimps, and fish fillets, without adding facilities and changing devices.

8. The frosting interval is long to ensure the continuity of production.

Advantages of fruit and vegetable quick freezing machine:

1. The speed of the two mesh belts is adjusted separately to meet the freezing needs of various foods.

2. Two variable speed belts: Under normal conditions, all kinds of food can be frozen without damage to the food and no sticking of the food.

3. Centrifugal fan: The system uses a high-pressure centrifugal fan to generate corresponding wind force within a large static pressure range to ensure the formation of a fluidized bed and prolong the frosting interval.

4. The frame of the device is made of hot-dip galvanized parts or stainless steel, and the air pressure box of each fan is separated separately to ensure that when the load is low, even if some fans stop running, it will not affect the normal operation of other fans.

5. The storage body is made of polyurethane foam sandwich double-sided stainless steel plate, which has good heat preservation and beautiful appearance.

6. The conveying mesh belt is made of stainless steel, and all parts in contact with food are made of stainless steel to ensure food hygiene requirements.

7. Electric control box: A separate control panel can perform independent electric start and control network transmission speed operations.
