Novel refrigeration system for ice cream machine

Abstract

The invention discloses a novel refrigeration system for an ice cream machine, comprising a compressor, a condenser, an electronic expansion valve, a production area and a four-way valve, wherein theproduction area comprises a stirring tank and a storage tank, and the electronic expansion valve is used in a refrigeration system. During refrigeration, a high-temperature high-pressure superheated steam working medium flows out of the compressor, enters the condenser to release heat and cool down, then enters the electronic expansion valve for throttling, and then becomes a low-temperature low-pressure liquid working medium, and the low-temperature low-pressure liquid working medium cools the stirring tank and the storage tank and finally flows back to the compressor for a next cycle. Duringheating, the coil of the four-way valve is adjusted, and a superheated steam flows out from an e-port of the four-way valve, and heats up the stirring tank and the storage tank separately. The advantages of the novel refrigeration system comprise that the stirring tank and the storage tank can fully absorb heat or release heat, and the electronic expansion valve can adjust the temperature of theproduction area according to system requirements, realizes digital control and remote control, improves product quality and ensures production efficiency, thereby achieving the purpose of efficientlyproducing different products.

Description

technical field [0001] The invention relates to food processing machinery, in particular to a novel refrigeration system for an ice cream machine. Background technique [0002] At present, a common ice cream machine cooling or heating system for the mixing cylinder and the storage cylinder is to connect the mixing cylinder and the storage cylinder in parallel, use two sets of throttling devices (thermal expansion valves) and add multiple solenoid valves and one-way valves. Valves are used to control cooling or heating in time. This system can be used for time-sharing and segmental cooling or heating. However, due to the addition of multiple solenoid valves and check valves, the refrigeration system is complicated, the production cost increases, and the system risk stability decreases. , also because the throttling device of this system uses thermal expansion valve, because the adjustment range of the evaporation temperature of the thermal expansion valve has certain limitati...

Valves are used to control cooling or heating in time. This system can be used for time-sharing and segmental cooling or heating. However, due to the addition of multiple solenoid valves and check valves, the refrigeration system is complicated, the production cost increases, and the system risk stability decreases. , also because the throttling device of this system uses thermal expansion valve, because the adjustment range of the evaporation temperature of the thermal expansion valve has certain limitations, and it can only be adjusted when debugging the machine, so it can only produce products with a relatively single temperature during refrigeration (ice cream)
