External dry type tube ice maker

Abstract

The invention discloses ice processing equipment, and particularly relates to an external dry type tube ice maker. The external dry type tube ice maker is technically characterized by comprising a first ice making barrel composed of ice making pipes and a refrigerating system, wherein the refrigerating system involves a compressor, a condenser and an expansion valve; the external dry type tube ice maker further comprises a water tank, a first water distributor and ice cutters, and the external dry type tube ice maker further comprises a first evaporator for dividing a refrigerant to wrap the ice making pipes; the first evaporator comprises an evaporation pipe which internally circulates the refrigerant and is spirally wound around the ice making pipes, and the evaporation pipe comprises a liquid inlet and an exhaust port; and the first evaporator further comprises a gas collection valve which communicates with the exhaust port and collects and feeds the high-temperature gaseous refrigerant in the evaporation pipe into the compressor, and a liquid distribution valve which communicates with the expansion valve and divides and injects a low-temperature liquid refrigerant in the expansion valve into the liquid inlet, and the refrigerating system further involves an electromagnetic valve for directly guiding the high-temperature gaseous refrigerant into the first evaporator for deicing. By using the external dry type tube ice maker, the refrigerating efficiency can be guaranteed, and the refrigerating cost is reduced by reducing the filling amount of the refrigerants.

Description

technical field [0001] The invention relates to the field of ice processing, in particular to an external dry tube ice machine. Background technique [0002] Tube ice machine is a kind of ice machine which is specialized in producing hollow tubular ice cubes with irregular length. The traditional tube ice machine uses a flooded evaporator to cool and produce tubular ice cubes. Its working principle is to pour raw material water into the heat exchange tube, and exchange heat by immersing the heat exchange tube in a liquid refrigerant, thereby exchanging heat. A tubular ice cube forms inside the tube. [0003] At present, the Chinese invention patent with the publication number CN104006594B discloses a tubular ice ice maker for both fresh water and sea water and its ice making process, including an ice making cylinder and a refrigeration system for cooling the ice making cylinder and operating as a refrigerant , the ice-making cylinder is sequentially provided with a water t...

AI Technical Summary

Problems solved by technology

Although this invention can produce tubular ice cubes, it needs to immerse the refrigeration tube in the refrigerant, the charging amount of refrigerant is large, and the cost of ice making is high.
