Refrigerating cylinder, ice cream machine comprising refrigerating cylinder, and manufacturing process of refrigerating cylinder

Abstract

The invention discloses a refrigerating cylinder, an ice cream machine comprising the refrigerating cylinder, and a manufacturing process of the refrigerating cylinder. The refrigerating cylinder comprises an inner cylinder, an outer cylinder and at least two tubular bodies, the outer cylinder sleeves the inner cylinder, the tubular bodies wind around the outer circumference of the inner cylinder,the tubular bodies are located between the inner cylinder and the outer cylinder, and two free ends of the tubular bodies stretch out from the side wall of the outer cylinder. At least one tubular body is filled with a refrigerant, and the refrigerant evaporates in the tubular bodies to absorb the heat of the ice cream slurry in the inner cylinder so as to complete the refrigeration function. Since the tubular bodies are located between the inner cylinder and the outer cylinder, the outer cylinder can ensure that the heat exchange between the tubular bodies and the inner cylinder is more uniform and the heat transfer efficiency is higher, the ice cream slurry in the inner cylinder is uniformly cooled. At least one tubular body is filled with a heating medium, and the circulation system ofthe ice cream machine controls the heating medium in the tubular bodies to heat the inner cylinder and performs high-temperature sterilization and disinfection on the inner cylinder when the inner cylinder needs to be sterilized and disinfected. The outer cylinder can ensure that the heat exchange between the tubular bodies and the inner cylinder is more uniform, and ensures the sterilization anddisinfection effect.

Description

[0002] When making ice cream, the refrigeration cylinder in the ice cream machine is a very important part. The current ice cream refrigeration cylinder generally uses a metal tube to wind the outer wall of the refrigeration cylinder. The refrigerant is passed into the metal tube to form the evaporation channel of the refrigerator. The refrigerant is in the metal tube Evaporation absorbs the heat of the ice cream slurry in the refrigeration cylinder to complete the cooling function. The existing refrigeration cylinder has low heat transfer efficiency and poor cooling effect. The ice cream slurry in the refrigeration cylinder is not cooled uniformly, which affects the taste of ice cream;

[0003] Moreover, the refrigeration cylinder needs to be sterilized regularly to ensure food hygiene. When the current refrigeration cylinder needs to be sterilized, a three-way or four-way valve is usually used to switch the state of the refrigerant in the metal tube, so that the refrigerant in the metal tube condenses and releases heat. The heat released by the refrigerant is used to heat and sterilize the inside of the refrigeration cylinder, but the temperature of the heat released by the condensation of the refrigerant in the metal tube is uncontrollable. If the temperature is too high, the protein of the ice cream slurry in the refrigeration cylinder will be damaged, seriously affecting The taste of ice cream, when the temperature is too low, the sterilization effect cannot be achieved
