Picking, pre-cooling and storing integrated basket, application thereof, and method for pre-cooling small-fruit-diameter perishable fruits

Abstract

The invention provides a picking, pre-cooling and storing integrated basket, application thereof, and a method for pre-cooling small-fruit-diameter perishable fruits, and belongs to the technical field of fruit and vegetable picking after-treatment. Based on the design of the picking, pre-cooling and storing integrated basket, the modes of standard picking, pre-cooling, storing boxes and trays areadopted, the method for pre-cooling small-fruit-diameter perishable fruits is successfully provided, standardization of a cold chain process is easily realized, semi-automatic operation in the process is realized, and labor and time are saved. Meanwhile, a critical freeze injury temperature method is adopted for delivering air, in this way, pre-cooling time can be effectively shortened, pre-cooling energy consumption can be effectively lowered, meanwhile, a quench effect can be realized in fruit and vegetable pre-cooling treatment, and the storing circulating deadline of follow-up steps is delayed; an alternate-air-delivery variable-air direction method is adopted, in this way, the uniformity of the pre-cooling process is improved, and the phenomenon of dead zones during pre-cooling heattransfer is prevented; a time-period-division variable-air speed air delivery mode is adopted, so that while the pre-cooling time is guaranteed, the pre-cooling energy consumption is lowered.

Description

technical field [0001] The invention belongs to the technical field of post-harvest treatment of fruits and vegetables, and in particular relates to a picking, precooling and storage integrated basket and its application, and a method for precooling small-diameter perishable fruits. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Small fruit diameter perishable fruits such as blueberries, cherries, strawberries and other post-harvest fruits are prone to aging, dehydration, rot and other phenomena. Taking blueberries as an example, studies have shown that delaying pre-cooling for 8 hours after harvesting blueberries will lose their commodity value. Therefore, it is of grea...

Problems solved by technology

[0004] At present, the commercialization process of post-harvest blueberries in China is picking-pre-cooling-grading-storage. With the increasingly important cold chain standardization, standardized picking baskets, pre-cooling baskets, and packaging have become the mainstream. At present, my country's blueberry pre-cooling equipment Most of the structure and process parameters are copied from foreign countries, and there is no theoretical basis to follow for pre-cooling. Some technological processes are difficult to adapt to the current domestic situation, resulting in large post-harvest blueberry losses.

[0005] Among the existing published patents, most of them are fresh-keeping methods for blueberries, mainly including temperature control, controlled atmosphere fresh-keeping, chemical fresh-keeping, high-voltage electrostatic field fresh-keeping, radiation fresh-keeping and coating fresh-keeping. Unpublished patent, as the first mile of the cold chain, the quality of the pre-cooling effect is very important to its subsequent quality
