Multifunctional efficient fruit and vegetable temperature shock processing device and operation method thereof

Abstract

The invention discloses a multifunctional efficient fruit and vegetable temperature shock processing device and an operation method of the multifunctional efficient fruit and vegetable temperature shock processing device. The multifunctional efficient fruit and vegetable temperature shock processing device comprises a heat pump system, a secondary refrigerant system and a fruit and vegetable processing system. The heat pump system is composed of a compressor, a four-way reversing valve, a heat exchanger, a throttling device and a first plate type heat exchanger. The secondary refrigerant system is composed of a first circulating pump, a fourth stop valve, the first plate type heat exchanger, a first three-way valve and a second plate type heat exchanger. The fruit and vegetable processing system is composed of the first plate type heat exchanger, the second plate type heat exchanger, a second three-way valve, a first three-way valve, a second circulating pump, an overcooling relieving device, a filter, a fruit and vegetable processing tank, a first stop valve, a second stop valve and a third stop valve. The heat pump system is respectively connected with the fruit and vegetable processing system and the secondary refrigerant system through the first plate type heat exchanger. The secondary refrigerant system is connected with the fruit and vegetable processing system through the second plate type heat exchangers. Respective operation of a hot water operation mode, a cold water operation mode and an ice slurry operation mode is achieved through conversion of the four-way reversing valve, the first three-way valve and the second three-way valve.

Description

Technical field [0001] The invention belongs to the pre-harvest pretreatment temperature stimulation technology of fruits and vegetables, and more specifically relates to a device that uses the principles of refrigeration and heat pump to perform cold and heat shock treatments on harvested vegetables and an operating method thereof. Background technique [0002] Fresh fruits and vegetables are increasingly becoming an indispensable part of people's daily diet because of their rich vitamins, inorganic salts, and plant fibers. However, its seasonal and regional characteristics, as well as rot and pathogen infection caused by improper post-harvest handling or storage, have caused serious post-harvest losses of fruits and vegetables in my country. The temperature-increasing treatment of fruits and vegetables after harvest has been widely used in recent years because of its better preservation effect and safety and environmental protection.
