The working principle of the processing flake ice machine (the working principle of the evaporator and the working principle of the refrigeration system) The working principle of the evaporator: After the flake ice machine works normally, the water pump pumps water from the water tank to the water diversion tray. The water is evenly sprayed on the inner wall of the ice bucket and forms an ice layer through the refrigeration cycle system. The ice blade is driven by the speed reducer to scrape the ice from the inner wall to form flakes of ice, which fall into the lower freezer for storage for later use. The ice-forming water flows into the water baffle, and then flows into the water tank to continue to circulate, thereby realizing the continuous ice making process.
The working principle of the 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 working medium, and then flows into the condenser to exchange heat with the outside world, and the heat released becomes a high-pressure liquid working medium. , After passing through the filter, it passes through the expansion valve to reduce the pressure and temperature to a vapor-liquid mixed state, and then enters the evaporator, exchanges heat with the water on the inner wall of the evaporator, absorbs a large amount of heat, and makes the water drop to the temperature below the freezing point sharply. Freeze instantly. At this time, the refrigerant evaporates into a gaseous state after absorbing heat, and is sucked into the compressor to circulate, so as to realize circulating refrigeration.
A brief description of the advantages of food processing flake ice machines. Food processing flake ice machines have advanced technology and good quality of ice production. Among similar products, they have low ice temperature (up to -8°C, or even lower), dry, non-caking, and flowing. Good performance, good hygiene, large contact area with fresh-keeping products, not easy to damage the fresh-keeping products, etc. And has:
- The ice making efficiency is high, and the cold loss small flake ice machine uses cold water to surround the spray to make ice. The entire evaporator fully contacts the water source and quickly evaporates to form an ice layer. The spiral ice blade quickly cuts the ice layer off. The evaporator and Evaporation pipes are protected by high-efficiency insulation layer, with little cooling loss;
2. The ice flakes are of good quality, dry and unbonded. The evaporator of the flake ice machine adopts a spiral groove structure design. The liquid supply is uniform and the evaporation efficiency is high. The thickness of the dry ice layer is generally 1.8~2.5mm, and the ice flakes are not easy to stick when dried, which is convenient for users to use;
3. Rich variety, simple structure, small footprint. Flake ice machines include fresh water type, sea water type, self-contained cold source, user-equipped cold source, and ice storage. The daily ice production capacity ranges from 400Kg/24h to 50000Kg/24h, etc. The user can choose the suitable model according to the use occasion and the water quality. The ice maker is small in size, simple in structure, easy to install, small in area, and low in noise. And other advantages, the use of the site is practical.
4. PLC programmable control system, stable performance, free control of flake ice machine using PLC programmable control system to achieve control, stable operating performance, safe and reliable, users can freely control the flake ice machine automatic start and automatic stop period according to the power consumption, Realize energy saving and automatic control.
5. Simple operation and high hygienic standards. The flake ice machine adopts fully automatic control, and the operator only needs to press the switch to operate. The evaporator is made of imported 304 stainless steel or carbon steel with high heat transfer efficiency. The surface is electroplated with hard surface treatment, which ensures the super corrosion resistance of the ice bucket and the cleanness of the ice flakes.
6. Complete fault protection device The flake ice machine is equipped with various protection devices such as high and low voltage, water cut, limit, overload, etc., which further enhances the safety and stability of the ice maker, allowing users to directly cut off the power when ice making is not required Stop ice making. The internal structure of the evaporator is simple, and the parts have high versatility, so the operation is reliable. Convenient maintenance and easy maintenance.
