Convenient and rapid pressure-difference pre-cooling vehicle

Abstract

The invention discloses a convenient and rapid pressure-difference pre-cooling vehicle. The convenient and rapid pressure-difference pre-cooling vehicle comprises a trolley (14) capable of freely moving; a hollow compartment (140) is arranged on the trolley (14); a refrigerating system is arranged on the compartment (140); the refrigerating system is in communication with the compartment (140); and the refrigerating system is used for cooling outside air and conveying the cooled air to the compartment (140). The invention discloses the convenient and rapid pressure-difference pre-cooling vehicle, which can guarantee that the picked fruits and vegetables are conveniently and rapidly cooled in fruit and vegetable production places; and moreover, the convenient and rapid pressure-difference pre-cooling vehicle has the advantages that hardware investment cost is low and the fruit and vegetable fresh-keeping cost can be reduced while the optimal qualities of the fruits and vegetables are guaranteed, is beneficial for wide promotion and application and is of great significance to the production practice.

Description

technical field [0001] The invention relates to the technical field of fruit and vegetable storage, in particular to a convenient and quick differential pressure pre-cooling car. Background technique [0002] At present, with the continuous improvement of people's living standards in our country, the quality requirements for foods such as fruits and vegetables (ie fruits and vegetables) are also getting higher and higher. For fruits and vegetables, which have just been picked from the field, because they are still undergoing respiration, they have very large field heat and respiratory heat, and they need to be cooled in time to ensure the quality of fruits and vegetables. [0003] At present, the methods commonly used for pre-cooling of fruits and vegetables mainly include differential pressure pre-cooling, vacuum pre-cooling and ice water pre-cooling. Among them, vacuum pre-cooling can quickly cool down fruits and vegetables, but its equipment investment is large, while ic...

AI Technical Summary

Problems solved by technology

Therefore, although the current differential pressure precooling equipment has a high investment cost, it has not been reasonably applied, and it is easy to be limited by power conditions in fruit and vegetable production areas far away from residential areas. Generally, it is necessary to further equip special power generation equipment for differential pressure The pre-cooling equipment is powered, which further increases the investment cost and seriously affects the widespread popularization and application of differential pressure pre-cooling equipment
