Energy-saving differential pressure type fruit and vegetable precooling warehouse

Abstract

The invention relates to an energy-saving differential pressure type fruit and vegetable precooling warehouse, comprising a warehouse body, a refrigeration system, a humidifier, a blower, a return fan and fruit and vegetable boxes; the warehouse body is formed by an air treatment chamber, an air return static pressure box, an air supply static pressure box and a precooling room; the precooling room is divided into multiple precooling room compartments by flexible roller shutters; an air return hole of a return air top plate and an air supply hole of an air supply floor are staggered left and right; an evaporator and the humidifier are arranged in the air treatment chamber, the blower is embedded in the inlet position of the air supply static pressure box, and the return fan is embedded in the outlet position of the air return static pressure box, and air holes are formed in side walls of the fruit and vegetable boxes. The energy-saving differential pressure type fruit and vegetable precooling warehouse has the beneficial effects that an operation mode of separating hot and cold air ducts before and after precooling and combining air supply and air return is adopted, and the humidifier for precooling is provided, so the characteristics that loss of refrigeration capacity for precooling is less, the precooling is uniform, the precooling speed is fast, water loss of fruits and vegetables is less, the precooling capacity is adjustable, energy is saved, the efficiency is high, and the like are achieved.

Description

technical field [0001] The invention relates to a fruit and vegetable pre-cooling system, in particular to an energy-saving differential pressure fruit and vegetable pre-cooling storage, which belongs to the technical field of fruit and vegetable preservation. Background technique [0002] my country is a large agricultural country, and the output of fruits and vegetables is the second largest agricultural industry after grain, and the annual output of fruits and vegetables ranks first in the world. However, compared with developed countries such as Europe and the United States, my country's post-harvest preservation technology for fruits and vegetables is seriously lagging behind. A complete and independent post-harvest cold chain for fruits and vegetables has not yet been formed. According to the statistics of the Food and Agriculture Organization of the United Nations (FAO), the direct economic loss caused by the postharvest loss of fruits and vegetables in my country is a...

AI Technical Summary

Problems solved by technology

It can be seen that the conventional fruit and vegetable pre-cooling storage has disadvantages such as unreasonable utilization of cooling capacity, chaotic organization of cold and hot air flow, low efficiency of fruit and vegetable pre-cooling, and uneven pre-cooling effect.
