Process for designing refrigerating barrel (evaporator) of ice cream machine

Abstract

The invention discloses a process for designing a refrigerating barrel (evaporator) of an ice cream machine. The process comprises that a fin (5) with an annular structure is adopted in an interlayer formed after an outer sleeve and an inner barrel are combined, the fin is formed by punching an iron plate, every two fins form a group (8) according to the process requirement, the annular fins are arranged in a mode that the openings of the annular fins are staggered for 180 degrees, and a plurality of groups of fins form a maze refrigerant passage in the interlayer of the refrigerating barrel, so that the structure of the evaporator of the ice cream machine is formed. The ice cream refrigerating barrel (evaporator) has the advantages of good refrigerating effect, stable quality, simple manufacturing process and low manufacturing cost.

Description

technical field [0001] The invention belongs to the food industry, and relates to the design and production technology of an ice cream refrigeration cylinder (evaporator). technical background [0002] The refrigeration cylinder (evaporator) is the most important key component of ice cream equipment. It involves the production quality of ice cream production and the stability of the machine's refrigeration system. The shape of the refrigeration cylinder of the ice cream machine is cylindrical, generally divided into an inner cylinder and an outer jacket. The interlayer has a refrigerant flowing through it to take away the heat of the ice cream slurry in the cylinder, thereby cooling the ice cream slurry and making the finished ice cream. In order to fully absorb the heat of the slurry, the design and technology of the existing refrigeration cylinder of the ice cream machine are relatively mature mainly as follows: [0003] ( figure 1 Schematic diagram of the technical str...

AI Technical Summary

Problems solved by technology

[0005] Disadvantages: The process is complicated. The process of winding fins and welding is difficult, the quality is unstable, and it is difficult to process the outer circle of fins after welding, and the labor cost is high.

[0008] Disadvantages: Cutting process is time-consuming, high cost, and the weight of the refrigeration cylinder is heavy. The cooling capacity in the early stage of the refrigeration process is absorbed and stored by the jacket, thus affecting the refrigeration efficiency.

[0011] Disadvantages: The cooling effect is generally due to the fact that the refrigerant needs to go through two wall thicknesses around the tube wall and the inner tube wall to take away the heat of the ice cream slurry from the inner tube, so the cooling effect Poor. (Foreign companies use inner cylinder materials with better thermal conductivity, but the cost is high).
