example 1

[0035] 1. The structure of the cooperative device for vacuum precooling, sterilization and preservation of fruits and vegetables: it includes a box body 3 and a program controller 8. One side of the box body 3 is provided with a door that can be opened and closed, which is convenient for picking and placing fruits and vegetables; the box body 3 is equipped with two A type of ultraviolet germicidal lamp 4; the bottom of the box 3 is provided with a vibrating base 6; the box 3 is connected to a vacuum device 9 through a pipeline, so that a vacuum is generated inside the box 3; the program controller 8 is a programmable control The PLC of the device can program the sterilization method and control the action of the ultraviolet germicidal lamp, the base and the vacuum device.

[0036] The two types of ultraviolet germicidal lamps are 185nm and 254nm ultraviolet germicidal lamps, which correspond to the sterilization methods I and II respectively. The opening and closing are control...

example 2

[0045] 1. The structure of the cooperative device for vacuum precooling, sterilization and fresh-keeping of fruits and vegetables: the installation method is the same as that in Example 1).

[0046] 2. Application of fruit and vegetable vacuum pre-cooling, sterilization and fresh-keeping collaborative device in strawberry fresh-keeping and quality preservation

[0047] Put the strawberries into the box in two boxes, place them symmetrically on the base of the box in two rows, and close the box; set various operating parameters on the program controller: the pre-cooling end temperature is 4°C, the sterilization method I (UV After 6 minutes of lamp irradiation time, continue ozone fumigation for 4 minutes) and sterilization method II (UV lamp irradiation time of 5 minutes), the travel speed of the electric walker is 5 cm / s, the vibration of the reciprocating vibrating seat is 240 times / min, and the wind speed of the gas agitation device is 50 m / s; turn on the electric walker, re...

Abstract

The invention relates to a fruit and vegetable vacuum precooling, sterilizing and fresh keeping synergy device and an application method thereof. The fruit and vegetable vacuum precooling, sterilizingand fresh keeping synergy device comprises a tank body and a procedure controller, wherein a door which can be opened and closed is arranged on one side of the tank body, so that fruits and vegetables are convenient to take and put; two types of ultraviolet sterilizing lamps which can be moved are arranged in the tank body; a base which can vibrate is arranged at the bottom of the tank body; thetank body is connected with a vacuumizing device through a pipeline, so that vacuum is generated in the tank body; and the procedure controller can edit and arrange a sterilizing manner, and control the motions of the sterilizing lamps, the base and the vacuumizing device. According to the fruit and vegetable vacuum precooling, sterilizing and fresh keeping synergy device disclosed by the invention, sterilization and disinfection can be performed at the same time in a vacuum precooling room, so that the synergistic reaction of ultraviolet, ozone and vacuum is sufficiently achieved, the problems that in the prior art, the operation time is too long, the sterilizing is not thorough, and the working place is polluted are effectively solved, the working efficiency is improved, and the damage on the fruits and the vegetables caused by transporting can also be reduced; and the fruit and vegetable vacuum precooling, sterilizing and fresh keeping synergy device has important effects on reducing damage of the fruits and the vegetables and improving product quality, and is suitable for storing, transporting, fresh keeping and producing of the fruits and the vegetables, and test of scientificresearch institutions.

Description

technical field [0001] The invention relates to the technical field of processing, storage and transportation of agricultural products, in particular to a device for precooling and sterilizing treatment of vegetables and fruits after harvesting and realizing all program functions in the same set of devices, specifically a fruit and vegetable A vacuum pre-cooling, sterilization and fresh-keeping cooperative device and a use method thereof. Background technique [0002] Fresh fruits and vegetables are still alive after picking, carrying out metabolic activities dominated by respiration. Due to being separated from the parent body, the supply of materials and energy is interrupted, and they can only rely on consuming their own carbohydrates, pectin, vitamins, organic acids and other substances to maintain life, resulting in a decline in the quality of vegetables. Pre-cooling is an effective measure to quickly remove field heat, inhibit its respiration, and maintain the freshne...
