Cold control system of ice cream machine, cold control method and ice cream machine

Abstract

The invention discloses a cold control system of an ice cream machine, a cold control method and the ice cream machine. The cold control system of the ice cream machine comprises a material tank, a freezing cylinder, a main pipeline, a material tank precooling branch and a freezing cylinder cooling branch. The cold control method comprises a material tank precooling control method, wherein the material tank precooling control method specifically comprises the following steps: detecting the temperature Tc of the material tank, and comparing the temperature Tc with a preset precooling temperature T1; detecting whether the ice cream machine is in an ice cream making process or not; and detecting whether the temperature Tc of the material tank is higher than a second preset temperature T3 or not. The cold control system has the beneficial effects that as one material tank precooling branch is arranged on the freezing cylinder cooling branch in parallel, an independent cooling system is notadditionally arranged, and the production cost of the equipment can be lowered; meanwhile, when ice cream is made by using a main cooling system, material tank precooling operation is not implemented, so that the quality of the ice cream can be stabile; and in addition, precooling is implemented intermediately when the material tank temperature is low, and together with a stirring device, the problem that material pulp is frozen when the material tank is precooled can be avoided.

Description

technical field [0001] The invention relates to the field of ice cream machine manufacturing, in particular to an ice cream machine cooling control system, a cooling control method and an ice cream machine. Background technique [0002] With the improvement of people's living standards, ice cream is becoming more and more popular, and the demand for ice cream machines is also increasing. In order to ensure that the slurry in the trough of the ice cream machine does not deteriorate, it is necessary to pre-cool the slurry in the trough. At the same time, when the business is not good or at night, the slurry in the refrigeration cylinder needs to be cooled and kept fresh. [0003] There are generally two ways to pre-cool the trough in the industry. One is to cool the trough through a separate refrigeration system. This method is expensive and requires an independent pre-cooling compressor, pre-cooling fan, and pre-cooling Condenser, etc.; and generally speaking, the power of t...

Problems solved by technology

[0003] There are generally two ways to pre-cool the trough in the industry. One is to cool the trough through a separate refrigeration system. This method is expensive and requires an independent pre-cooling compressor, pre-cooling fan, and pre-cooling Condenser, etc.; and generally speaking, the power of the pre-cooling compressor is low, resulting in low pre-cooling efficiency and long pre-cooling time; in addition, after adding an independent refrigeration system, the electronic control system of the ice cream machine is more complicated, thus resulting in higher maintenance rates;

[0004] Another method is to add a solenoid valve to the main refrigeration system to control the switch of the pre-cooling function, but this method can only be pre-cooled by artificial control, and it will take up the cooling capacity of the main refrigeration system during pre-cooling. The amount will seriously affect the main refrigeration system, affecting the production progress and quality of ice cream; in addition, due to the high power of the main refrigeration system, it is easy to freeze the slurry in the trough, which will affect the output, resulting in the failure of ice cream production, or even Can seriously affect the ice cream machine
