Working principle of refrigeration system of food processing flake ice machine

The food processing flake ice machine is the huge heat generated during the processing and mixing of bread, biscuits, cakes, meat products, aquatic products, etc. It needs to use flake ice for temperature adjustment to achieve the freshness preservation effect and ensure product quality. It is to use flake ice Cool quickly to prevent fermentation.

working principle

After the flake ice machine works normally, the water pump pumps water from the water tank to the water distribution tray. Driven by the reducer, the water in the tray is evenly sprayed onto the inner wall of the ice bucket, and forms an ice layer through the refrigeration cycle system. The ice blade is driven by the reducer. Next, the ice is scraped from the inner wall to form flake ice, which is dropped into the lower ice storage cabinet for storage and ready for use. The unfrozen water flows into the water baffle, and then into the water tank to continue circulation, thereby realizing the process of continuous ice making.

Working principle of refrigeration system:

When the refrigeration system works normally, the refrigerant (refrigerant) is compressed by the compressor to become a high-temperature and high-pressure steam refrigerant, and then flows into the condenser to exchange heat with the outside world, and the heat is released to become a high-pressure liquid refrigerant, which flows through the filter to filter After that, the pressure and temperature of the expansion valve are reduced to a mixed state of vapor and liquid, and then it enters the evaporator to exchange heat with the water on the inner wall of the evaporator, absorbing a large amount of heat, so that the water drops sharply to a temperature below the freezing point, and freezes instantly. At this time, the refrigerant evaporates into a gaseous state after absorbing heat, and is sucked into the compressor for circulation, thereby realizing cycle refrigeration.

A brief description of the advantages of food processing flake ice machines

Food processing flake ice machine, advanced technology, good ice quality, low ice temperature (up to -8 ℃ or even lower), dry, not easy to agglomerate, good fluidity, good hygiene, and freshness preservation among similar products The product contact area is large, and it is not easy to damage fresh products. and have:

1. High ice-making efficiency and low cooling loss

The flake ice machine uses cold water to surround and spray ice. The entire evaporator fully contacts the water source and quickly evaporates to form an ice layer. The spiral ice knife quickly cuts and scrapes the formed ice layer. Small volume loss;

2. The quality of borneol is good, dry and not sticky

The evaporator of the flake ice machine adopts a spiral groove structure design, which has uniform liquid supply and high evaporation efficiency. The water dripping onto the ice bucket can fully exchange heat with the refrigerant to form a thick and dry ice layer, generally with a thickness of up to 1.8 ~2.5mm, the borneol is dry and not easy to stick, which is convenient for users to use;

3. Rich varieties, simple structure, small footprint

Flake ice machines include fresh water type, sea water type, self-contained cold source, user-provided cold source, ice storage and other series. The daily ice production capacity ranges from 400Kg/24h-50000Kg/24h and other specifications. Users can choose a suitable model according to the application occasion and water quality. The ice machine is small in size, simple in structure, easy to install, small in floor space and low in noise. And other advantages, the use of the site is good.

4. PLC programmable control system, stable performance, free control

The flake ice machine is controlled by a PLC programmable control system, with stable operation performance, safety and reliability. Users can freely control the automatic start-up and automatic shutdown periods of the flake ice machine according to the power consumption, so as to realize energy saving and fully automatic control.

5. Simple operation and high hygienic standard

The flake ice machine adopts automatic control, and the operator only needs to press the switch to start the operation. The material of the evaporator is made of imported 304 stainless steel or carbon steel with high heat transfer efficiency, and the surface is electroplated with chrome, which ensures the super corrosion resistance of the ice bucket and the cleanliness of ice flakes.

6. Perfect fault protection device

The flake ice machine is equipped with various protection devices such as high and low pressure, water shortage, limit, overload, etc., which further enhances the safety and stability of the ice machine, allowing users to directly cut off the power to stop ice making when they do not need ice making. The internal structure of the evaporator is simple, and the components are highly versatile, so the operation is reliable. It is easy to repair and maintain.
