Strawberry fresh-keeping device and fresh-keeping method

Abstract

The invention discloses a strawberry fresh-keeping device. The device comprises a box body; a storage rack with strawberry storage grids is arranged in the box body; an exhaust fan and an electrostatic spraying device are respectively arranged on the left side and the right side of the inner wall of the box body; and a ventilation opening is formed in the top of the box body. The invention also provides a strawberry fresh-keeping method, wherein the strawberry fresh-keeping method is implemented by using the strawberry fresh-keeping device. The strawberry fresh-keeping method comprises the following steps: placing strawberries into the strawberry storage grids of the strawberry fresh-keeping device; and processing the strawberries by using a plant essential oil emulsion sprayed by the electrostatic spraying device to complete strawberry fresh-keeping. The strawberry fresh-keeping device provided by the invention realizes sterilization treatment of strawberries, maintains quality of harvested strawberries, avoids mechanical damage in storing and transporting processes of the harvested strawberries, and prolongs the shelf life of the strawberries.

Description

technical field [0001] The invention relates to the field of fresh-keeping storage and transportation devices for fruits and vegetables, in particular to a strawberry fresh-keeping device and a fresh-keeping method. Background technique [0002] Strawberries are rich in nutrition, rich in vitamins, minerals, sugars, amino acids and anthocyanins and other biologically active substances. In a large country, the annual output of strawberries accounts for more than 30% of the world's strawberry production. However, strawberries are berries with high water content and soft quality. Even in the domestic sales and circulation, the post-harvest loss of strawberries has also caused huge economic losses. my country's current strawberry storage and transportation technology needs to be strengthened. [0003] Among the rot of strawberries, Botrytis cinerea caused by Botrytis cinerea is one of the main reasons. When strawberries are picked, the surface of seemingly healthy strawberries is...

Problems solved by technology

[0004] At present, in the process of strawberry fresh fruit logistics and transshipment, large-capacity cartons and wooden plates are generally used for storage, or small plastic boxes are used for packaging and then packing. These devices need to manually place strawberries layer by layer. However, even so This traditional strawberry storage device is also very easy to cause mechanical damage to strawberries, further reducing the shelf life of strawberries.

[0005] The existing strawberry preservation methods mainly include controlled atmosphere, heat treatment, edible smearing, corrugated box coating, irradiation, etc. Most of these methods require secondary manual treatment of strawberries after picking, which will inevitably introduce more mechanical damage. Most of these methods are not equipped with devices for berry strawberries. At the same time, the current post-harvest preservation methods do not take the storage and transportation process of strawberries into consideration, so it is difficult to solve the problem that strawberries will be exposed to high temperature, high humidity, external pathogens, And practical problems such as mechanical damage caused by bumps
