An integrated basket for picking, precooling and storage, application thereof, and precooling method for perishable fruits with small diameters

Abstract

The invention provides an integrated basket for picking, pre-cooling and storage, an application thereof, and a pre-cooling method for small-diameter perishable fruits, belonging to the technical field of post-harvest processing of fruits and vegetables. Based on the design of an integrated basket for picking, pre-cooling and storage, the present invention adopts standard picking, pre-cooling, storage boxes, trays and other methods to successfully propose a pre-cooling method for perishable fruits with small diameters, which is conducive to realizing the cold chain process. standardization, realizing semi-automatic operation in its process, saving manpower and time. At the same time, the invention adopts the method of critical freezing injury temperature to supply air, which can effectively reduce the pre-cooling time and energy consumption of pre-cooling. The pre-cooling method of supplying air with variable wind direction improves the uniformity of the pre-cooling process and stops the dead zone phenomenon of pre-cooling and heat transfer. energy consumption.

Description

technical field [0001] The invention belongs to the technical field of post-harvest processing of fruits and vegetables, and in particular relates to an integrated basket for picking, pre-cooling and storage, an application thereof, and a method for pre-cooling small-diameter perishable fruits. Background technique [0002] The disclosure of information in this Background section is only for enhancement of understanding of the general background of the invention and should not necessarily be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. [0003] Small fruit diameter perishable fruits such as blueberries, cherries, strawberries and other post-harvest fruits are prone to senescence, dehydration and rot. Taking blueberries as an example, research has shown that blueberries lose their commercial value after 8 hours of delayed pre-cooling after harvesting. Therefore, it is ve...

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
