Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as figure 1 As shown, the cold storage 1 is provided with a vertical partition 2 and a horizontal partition 3; the vertical partition 2 is arranged close to the side wall of the cold storage, and the cold storage 1 is divided into a working area and a return air area 4; the horizontal partition 3 is arranged near the top of the cold storage, and the horizontal One of the three sides of the partition 3 is connected to the vertical partition 2, the two sides are connected to the two side walls of the cold storage, and the side wall of the cold storage opposite to the vertical partition 2 is separated from the other side of the horizontal partition 3 to form an air passage; The transverse partition 3 divides the working area into an upper intake area 5 and a lower precooling area 6 . The inner wall of the cold storage 1 is c...

Abstract

The invention discloses an intelligent agricultural product differential pressure precooling system adopting ice slurry. The interior of the refrigeration house is divided into an air inlet area, a pre-cooling area and an air return area through a vertical partition and a transverse partition. An air inlet of the heat exchanger is communicated with the lower portion of the air return area, an air outlet of the heat exchanger is connected with the air cooler, and the ice slurry generator is connected with the heat exchanger through a pipeline. And a plurality of exhaust fans are embedded on the vertical partition of the air return area to form pressure difference. A goods shelf and a pre-cooling box are arranged in the pre-cooling area, and a temperature sensor and a humidity sensor are arranged in the pre-cooling area. And the temperature sensor, the humidity sensor, the ice slurry generator and the air cooler are connected with the control device. The air pumped into the air return area still has certain moisture and low temperature, is not directly discharged to the outside, but enters the heat exchanger for circulating heat exchange, and the problem of water loss in the traditional differential pressure precooling process is effectively solved. The problem that an existing pressure difference pre-cooling technology cannot be automatically and intelligently adjusted is solved, and the refrigeration efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and relates to a differential pressure precooling system for agricultural products, in particular to an intelligent differential pressure precooling system using liquid ice for post-harvest storage and transportation of agricultural products such as fruits and vegetables. Background technique [0002] At present, my country's demand for agricultural products such as fruits and vegetables is constantly increasing. Due to the short shelf life of fruits and vegetables picked in summer, they are easy to spoil during storage and transportation. Using pre-cooling to treat fruits and vegetables can greatly reduce the respiration of fruits and vegetables, slow down the reproduction of microorganisms and enzymes, thereby prolonging the shelf life and improving the economic benefits of agricultural products. Pre-cooling refers to the cooling of agricultural products in a short period of time. The exi...
