Technical Field

The invention relates to the field of ice making, in particular to a heat exchange enhancement method of an ice crystal crystallizer.

Background

An ice crystal crystallizer is the core component of an ice making machine. Such as flake ice machines of industrial ice making machines. The ice produced by the ice crystal crystallizer is flaky. The flake ice can be made of fresh water or salt water. The flake ice is flake and loose ice, the thickness is 1 mm to 10 mm, the shape of the product surface is irregular, and the diameter is about 5 mm to 50 mm. The flake ice has no sharp edges and corners, and can not stab frozen objects. Can enter the gap between the cooled objects, reduces heat exchange, keeps the temperature of ice and has good heat preservation effect. The flake ice machine has the characteristics of excellent refrigeration effect, large refrigeration capacity and rapidness, so that the flake ice machine is mainly applied to various large-scale refrigeration facilities, quick freezing of foods, concrete cooling and the like.

The main body of the ice sheet making machine is divided into two cavities, wherein the outer cavity is internally provided with a copper pipe with certain density, the inner cavity is internally provided with a regular round stainless steel body, the distance between the center of the stainless steel body and the inner wall of the stainless steel body is a certain distance which can be automatically adjusted, and the distance is generally 3 mm. The water distributor is arranged above the ice skate and is provided with a plurality of groups of nozzles which are uniformly distributed, the working principle is that when the ice skate is started, water is pumped into the water distributor and is uniformly sprayed to the surface of the inner cavity, ice with certain thickness is formed instantly on the refrigerating surface of the outer cavity, and the just-made ice is beaten into small pieces and falls into the storage bin under the action of the rotating ice skate. When the refrigerant on the flake ice machine works, the compressor operates and then performs air suction, compression, air exhaust, condensation, throttling and heat absorption vaporization in the ice crystal crystallizer at the low temperature of minus 20 to minus 50. When the ice layer condenses to a certain thickness. After the evaporation temperature of the refrigerant reaches the set temperature of temperature control, the refrigerant is deiced in a common heat pump mode, and then the next cycle is realized.

In conclusion, the flake ice machine in the prior art has the defects of complex structure, high production and maintenance cost, unstable work and low effect.

The ice making machine utilizes the seed crystal and ice-water mixture to make ice on the special-shaped cooling surface, and has the advantages of high ice making efficiency, small cold loss, low energy efficiency, good quality of prepared flake ice, simple structure and convenient and reliable operation.
