A mobile differential pressure precooling device

Abstract

The invention relates to a movable type differential pressure precooling device. The movable type differential pressure precooling device comprises a controller and a square box body, wherein self-locking mobile wheels are arranged at the bottom of the box body; a goods feed inlet and a goods discharge outlet are formed in the side walls of the box body; square refrigeration units are arranged in the center of the inside of the box body; a square transfer channel encircling the refrigeration units for a circle is arranged between the side walls of the refrigeration units and the side walls of the box body; transfer direction conversion units are arranged at the four corners of the transfer channel correspondingly; cold wind outlets distributed vertically are formed in the four side walls of each refrigeration unit correspondingly; and a cooling capacity adjust and control cover plate is arranged outside each cold wind outlet. The movable type differential pressure precooling device has the beneficial effects of improving precooling efficiency and precooling quality, facilitating the achievement of unattended and refined management, prolonging the preservation time of fresh fruits and vegetables, mushrooms and other agricultural products, improving product quality and quality safety, reducing labor cost, and having good economical benefits and promotion value.

Description

technical field [0001] The invention relates to a mobile differential pressure precooling device. Background technique [0002] Fresh fruits, vegetables, bacteria and other agricultural products are rich in nutrition and are indispensable food in people's life. However, agricultural products such as fresh fruits, vegetables, and fungi have the characteristics of high moisture content, strong postharvest metabolism, seasonality, regionality, and product perishability. posed great difficulties. my country is a big producer of fresh fruits, vegetables, fungi and other agricultural products. For many years, the output of fresh fruits, vegetables, fungi and other agricultural products has been ranked first in the world. Problems such as high circulation losses, large price fluctuations, and inability to guarantee quality and safety are very prominent. [0003] With the continuous improvement of national living standards, people are not only satisfied with the supply of fresh fr...

AI Technical Summary

Problems solved by technology

At present, the degree of post-harvest commercialization of fresh agricultural products in my country is less than 15%, and the design and development of special pre-cooling facilities and the pre-cooling treatment of production areas are almost in a blank state, which seriously restricts the post-harvest value-added potential of fresh agricultural products in my country. An important bottleneck for leaping from a big producer of fresh agricultural products to a strong producer

Due to the lack of special pre-cooling facilities, many cold chain circulation enterprises can only put the harvested fresh agricultural products into cold storage for cooling treatment. Not only is the cooling efficiency low, but improper handling will seriously affect the sensory quality of the products; very few cold chain Although distribution companies have introduced differential pressure pre-cooling facilities, they are extremely inconvenient to use because their positions are fixed and cannot be moved, and because a large amount of cold air is usually lost from the gaps in product packaging containers, resulting in poor pre-cooling effect and slow cooling speed. slow, uneven cooling, and high energy consumption. Therefore, it is of great practical significance to research and develop a new type of mobile and layered differential pressure cooling device with high efficiency and low energy consumption.
