Problems solved by technology

Existing evaporators generally have three structures. The first structure includes the inner steel cylinder of the evaporator and the evaporation copper tube coiled on the inner steel cylinder of the evaporator. The copper tube of this type of evaporator has less contact surface with the inner steel cylinder. After the refrigerant flows into the copper tube, there is a layer of copper tube between the inner steel cylinder. The cooling efficiency is low, the power consumption is large, and it is not energy-saving. When manufacturing, each inner steel cylinder is coiled with a copper tube, and the copper tube and the surface of the inner steel cylinder are still in contact with each other. It is necessary to melt solder to increase the contact surface between the copper tube and the steel cylinder. The process is cumbersome, the processing time is long, the production efficiency is low, the labor intensity of the workers is high, and the material cost and labor cost are increased; the second structure includes the steel cylinder in the evaporator. The outer wall is equipped with the same cylindrical outer steel cylinder of the evaporator, and a spiral interlayer is set between the inner and outer steel cylinders. The inner, outer steel cylinder and interlayer have a three-layer structure, and the wall surface of the outer steel cylinder is a smooth arc. The third structure includes an outer steel cylinder on the outer wall of the inner steel cylinder of the evaporator. The outer wall of the outer steel cylinder is a smooth arc surface, and the inner wall is made with spiral grooves. The cylindrical outer steel cylinder To process the spiral groove on the inner wall, it needs to be placed on the machine tool to file the spiral groove on the inner wall with a file. The processing is very laborious and time-consuming, the production efficiency is low, and the manufacturing cost is high.

Description

technical field [0001] The invention relates to an ice cream machine evaporator, in particular to a spiral outer steel cylinder of the ice cream machine evaporator and a processing method thereof. Background technique [0002] Ice cream has the characteristics of smooth and delicate, cool and delicious. Especially in summer, people like to eat more. The ice cream machine mainly includes a refrigeration system and an extrusion system, and the refrigeration system includes a compressor, a condenser, a filter, a solenoid valve, a capillary tube and an evaporator. Existing evaporators generally have three structures. The first structure includes the inner steel cylinder of the evaporator and the evaporation copper tube coiled on the inner steel cylinder of the evaporator. The copper tube of this type of evaporator has less contact surface with the inner steel cylinder. After the refrigerant flows into the copper tube, there is a layer of copper tube between the inner steel cyl...
