Example Embodiment

[0011] See figure 1 with figure 2 , The box 1 of the fruit in-situ rapid pre-cooling machine is a square flat-walled structure, and is filled with high-density insulation materials with stainless steel sheets, including the inner wall, the outer wall and the insulation material sandwiched between the inner wall and the outer wall. The inner and outer walls are stainless steel plates. The thermal insulation material is polystyrene foam (EPS), which has good thermal insulation performance and light weight. The box 1 is provided with a pre-cooling chamber 11 and a refrigerating chamber 12. The bottom of the box 1 is equipped with 4 wheels, and the weight of the whole machine is less than 100 kg, which is convenient for field transportation.

[0012] See image 3 , The refrigeration device includes a compressor 21, a condenser 22, a liquid storage tube 23, and an evaporator 24 connected in sequence through pipelines. The compressor 21, the condenser 22 and the liquid storage tube 2...

Abstract

The invention relates to an in-situ quick precooling machine for fruits. The in-situ quick precooling machine for fruits comprises a box body, a refrigerating device, a dehumidifying device, a controldevice and a sterilizing device, wherein a precooling chamber and a refrigerating chamber are arranged in the box body; the refrigerating device comprises a compressor, a condenser, a liquid storingdrum and an evaporator sequentially connected by pipelines; the compressor, the condenser and the liquid storing drum are arranged in the refrigerating chamber; the evaporator is arranged in the precooling chamber; the evaporator comprises evaporating finned tubes and fans; the dehumidifying device comprises an electric heater and a water discharge valve; the electric heater is arranged on one side of the evaporating finned tubes; the water discharge valve is arranged at the bottom of the precooling chamber; and the sterilizing device is arranged in the precooling chamber. The in-situ quick precooling machine for fruits has high refrigerating speed, has dehumidifying and sterilizing functions, can effectively maintain the after-harvest quality of berries, and is light in weight of completemachine and convenient to carry and move in the field.

Description

technical field [0001] The invention relates to the technical field of fruit precooling equipment, in particular to an on-site rapid precooling machine for fruits. Background technique [0002] Fruits carry a large amount of field heat after harvesting, which accelerates their respiration intensity. Mechanical injuries during harvesting will further enhance respiration, releasing a large amount of respiratory heat, causing fruit temperature to rise, thereby accelerating quality decline and rotting and aging. Therefore, it is the key to maintain the freshness and nutritional value of fruits after they are harvested and cooled to a low temperature before they enter storage or circulation. At present, developed countries such as Europe, America and Japan regard post-harvest cooling of fruits and vegetables as an essential process. Fruits such as bayberry and blueberry are harvested in high temperature and rainy seasons. Timely pre-cooling can inhibit respiration, reduce nutrie...
