Fruit and vegetable producing area precooling vehicle

Abstract

The invention discloses a fruit and vegetable producing area precooling vehicle which comprises a precooling boxcar, a precooling vehicle body, an air returning top plate, a return fan, a boxcar inner partition plate, a throttle valve, a condenser, a compressor, an evaporator, a supply fan, an air supplying floor and fruit and vegetable precooling boxes. The precooling boxcar is divided into an air treatment chamber and a fruit and vegetable precooling chamber by the boxcar inner partition plate, the air returning top plate is installed on the upper portion of the fruit and vegetable precooling chamber, the air supplying floor is installed on the lower portion of the fruit and vegetable precooling chamber, and vent holes are formed in the air returning top plate and the air supplying floor respectively; the compressor, the condenser, the throttle valve and the evaporator are connected end to end to form a circulation loop; the supply fan is installed at an inlet of an air supplying channel, and the return fan is installed at an outlet of an air returning channel; the outer surfaces of the fruit and vegetable precooling boxes are provided with vent holes, and the fruit and vegetable precooling boxes are stacked on the air supplying floor in the fruit and vegetable precooling chamber in rows; the compressor is driven by an engine of the precooling vehicle body, and an electric power system of the precooling vehicle body supplies power to the supply fan and the return fan for operation. The fruit and vegetable producing area precooling vehicle has the advantages of being flexible, convenient to operate, rapid in precooling and the like.

Description

technical field [0001] The invention relates to a fruit and vegetable pre-cooling equipment, in particular to a fruit and vegetable producing area pre-cooling car, which belongs to the technical field of fruit and vegetable cold chain transportation. Background technique [0002] Fresh fruits and vegetables have rich nutritional value and are indispensable nutritional and health food in people's life, but the annual post-harvest loss of fruits and vegetables in our country is astonishing. The annual loss of fruit and vegetables after harvest in our country is as high as 25% to 30%, and the annual direct economic loss is as high as 80 billion yuan, seriously affecting the national economy. This is directly related to the lag in the development of my country's post-harvest fruit and vegetable preservation and cold chain logistics industries. Harvested fruits and vegetables are living organisms, which still have respiration and transpiration. The temperature of the harvested ...
