Embodiment 1

[0041] The ice cream machine of the present invention includes a freezing cylinder with a stirrer, a main refrigeration system and a control system, such as figure 1 As shown, the main refrigeration system includes a refrigeration circuit composed of a compressor 2, a condenser 3, a throttling device, and an evaporator 1 connected by a refrigeration pipeline. A filter is installed on the refrigeration pipeline between the throttling device and the condenser 3. 4, the control system controls the operation of the ice cream machine, including controlling the main refrigeration system to cool the ice cream in the freezing cylinder and controlling the agitator to stir, the throttling device is an electronic expansion valve 5, so The control system is also used to obtain the real-time forming degree value of the ice cream material in the freezing cylinder, and to feedback control the valve opening degree of the electronic expansion valve 5 through the forming degree value;

[0042] The...

Embodiment 2

[0050] The difference from the first embodiment is that this embodiment reflects the difference between the real-time forming degree value of the ice cream material in the freezing cylinder and the initial value of the forming degree through the change of the rotation speed value of the working motor of the mixer. That is, in this embodiment, the valve opening of the electronic expansion valve 5 is adjusted by feedback of the rotational speed value of the working motor of the agitator. During the forming process when the ice cream material in the freezing cylinder changes from liquid state to solid-liquid mixed state to solid state, until it reaches the final hardness / viscosity preset by the control system, the current value of the working motor of the agitator will gradually increase, and The speed value will gradually decrease according to this changing law. The real-time forming degree value of the ice cream material in the freezing cylinder can be judged by the rotational s...

Embodiment 3

[0053] The difference from Embodiment 1 and Embodiment 2 is that this embodiment reflects the difference between the real-time forming degree value of the ice cream material in the freezing cylinder and the initial value of the forming degree through the change of the evaporation temperature value in the main refrigeration system. The evaporation temperature value is the evaporation temperature of the evaporator in the main refrigeration system.

[0054] When the ice cream machine is working in each gear, the forming value of the ice cream material in the freezing cylinder gradually increases with the decrease of the evaporation temperature. According to this change rule, the ice cream in the freezing cylinder can be obtained by collecting the real-time evaporation temperature value in the main refrigeration system The molding degree value of the material.

[0055] In this embodiment, the control system presets a set of evaporation temperature thresholds X for each gear. 1~n , Wher...

Abstract

The invention discloses a refrigeration control method of an ice cream machine. The ice cream machine comprises a freezing cylinder with a stirrer, a main refrigerating system and a control system. The main refrigerating system comprises a refrigerating loop formed by connecting a compressor, a condenser, a throttling device and an evaporator through a refrigerating pipeline. The control system controls the main refrigerating system to refrigerate ice cream in the freezing cylinder and controls the stirrer to perform stirring. The throttling device is an electronic expansion valve. The controlsystem is further used for acquiring a real-time forming degree value of ice cream materials in the freezing cylinder and controlling the valve opening degree of the electronic expansion valve through forming degree value feedback. The forming degree value is a forming value divided according to the forming degree in the hardness / or viscosity ice cream forming process of ice cream material liquidstate-solid mixed state-solid state-system setting; and the control system controls the valve opening degree of the electronic expansion valve to change along with the change of the forming degree value. The refrigerating capacity in the ice cream material forming process can be accurately controlled.

Description

Technical field [0001] The invention relates to a refrigeration control method of an ice cream machine. Background technique [0002] The existing ice cream machine usually consists of a bowl, a freezing cylinder, a discharge assembly, a main refrigeration system and a control system, etc. The freezing cylinder is equipped with an agitator. The working process of the ice cream machine is generally: the main refrigeration system and the agitator are controlled by the control system. The ice cream slurry enters the freezing cylinder through the bowl. The ice cream slurry in the freezing cylinder is gradually cooled and solidified until it reaches the system. The set degree of ice cream molding. [0003] The main refrigeration system of an ice cream machine is generally composed of a compressor, a condenser, a throttling device, an evaporator, etc., which cools the ice cream material in the bowl and freezing cylinder. [0004] The ice cream machine cools the liquid ice cream entering ...
