Abstract
The utility model provides a device for preserving fruits and vegetables by adsorbing preservatives under reduced pressure. The device consists of a reduced pressure resistant storage container, a preservative volatilization container, stop valves and an electric cabinet, wherein the reduced pressure resistant storage container with fixed volume is connected with a matched reduced pressure vacuum pump by virtue of a stop valve; a reduced pressure stop valve is installed between the storage container and the outside; the preservative volatilization container is communicated with the storage container by a stop valve; and the switches of all the stop valves are controlled by electrical elements in the electric cabinet and can realize automatic and manual control modes. The device has the following advantages: the preservatives are fully contacted with the fruits and vegetables in the state of gas and the action form of the preservatives is changed from spontaneous contact to forced contact, thus saving the treatment time and improving the uniformity and the action effect; and the method can be simultaneously carried out in combination with the quick precooling treatment link of the fruits and vegetables, thus obviously improving the effect of preservation treatment after fruit and vegetable picking and the production speed.
Description
Affiliated field
The utility model patent belongs to preserving fruit and vegetable utilizing equipment, particularly a kind of device of the absorption antistaling agent fruit and vegetable preservation that reduces pressure.
Technical background
According to data; China's fruit and vegetable food has nearly 20%～35% the proportion of goods damageds in adopting back storage fresh-keeping process; Adopt the back product ommercialization Preservation Treatment proportion of goods damageds with developed country and be lower than 5% and compare and differ greatly, therefore, exploitation with promote new postharvest fruit and vegetable Preservation Treatment technology; Have crucial meaning to improving the commercialization treatment technology of fruits and vegetables in the cold chain process of circulation and producing high-quality fruit and vegetable food, can promote the big circulation of the domestic and international market of China's fruits and vegetables.
As everyone knows, ruckbildung appears in part postharvest fruit and vegetable easily, is because fruits and vegetables self metabolism has produced a kind of natural ripener---ethene.Ethene is as promoting ripe old and feeble plant hormone, and the associated receptor inner with fruits and vegetables cell tissue combines, and activates a series of and ripe relevant biochemical reactions, has accelerated the old and feeble and dead of fruits and vegetables.Especially in airtight fruit vegetables storing packing or space; Ethylene gas produces self-dematuration to fruits and vegetables self and strengthens gradually along with the prolongation of storage period builds up, and affects the eubolism of fruits and vegetables; Quicken the senescence process of fruits and vegetables, shortened the storage period of fruits and vegetables.
1-MCP (1-methyl cyclopropene) is a kind of inhibitor of very effective ethylene action, can combine with ethylene receptor well, has suppressed the generation of ethene, has slowed down the ripe old and feeble biochemical reactions of fruits and vegetables self.In production practices, can before plant endogenous ethene generation or exogenous ethylene effect, use the 1-MCP antistaling agent and handle; 1-MCP tries to be the first and combines with ethylene receptor; Thereby prevention ethene combines with its acceptor, has postponed maturation well, reaches fresh-keeping effect.
At present, in China many units having been arranged is the antistaling agent commodity of effective ingredient selling with 1-MCP.Gaseous state shape, tablet shape, pulvis shape, graininess are arranged on the antistaling agent physical form; Such antistaling agent in use; The gaseous state form can directly charge in the closed container, and the antistaling agent of other solid-state form all is employed in fixing airtight container or the space with this antistaling agent and adds that sustained release agent carries out release action and the antistaling agent that produces gaseous state, and storage space is interior to be contacted with fruit and vegetable surfaces thereby be diffused into; Act on fruits and vegetables and produce fresh-keeping effect, prolong the freshness date or the shelf life of fruits and vegetables.
But, in processing procedure, the 1-MCP antistaling agent of various states is discharged in the storage space, use the storage fruit and vegetable surfaces equably, relatively difficulty.Especially for bigger storage container or space; Like whole storage; Operating personnel must enter into storage and operate, and through sustained release agent 1-MCP gas are discharged, then speed away storage container and seal storage container immediately of operating personnel; Otherwise can cause 1-MCP gas to leak into outside the storage container, not reach action effect.In addition, also make operating personnel suck 1-MCP gases affect health easily.
Apparatus of the present invention are that a kind of device that reduces pressure absorption antistaling agent fruit and vegetable preservation then can overcome the above problems effectively, reach the purpose of fruit and vegetable preservation.
Summary of the invention
This patent technical problem to be solved is: the device that a kind of absorption antistaling agent fruit and vegetable preservation that reduces pressure is provided.
The patent art scheme is:
A kind of device of the absorption antistaling agent fruit and vegetable preservation that reduces pressure; It is characterized in that: make the long-pending container of anti-subatmospheric pressure storage of a constant volume; Be connected and installed the reduced vacuum pump that is complementary through stop valve; A decompression section valve is installed between the storage container and the external world, in storage container, is cut apart the sub-fraction space and process antistaling agent volatilization container, antistaling agent volatilization container is installed and is cut valve feeding storage container.The switch of each section valve is all controlled through the electronic auto-control element in the electric appliance control box, and can realize automatic and manual two kinds of control modes.
Functional advantage and result of use:
Carry out the Preservation Treatment of fruits and vegetables through patent device, improved production efficiency, practiced thrift the labour.At first, change the method that the method that must adopt manual work at present applies the 1-MCP antistaling agent, realized manual and the automation mode is controlled, improved operating efficiency; Secondly; Make the 1-MCP antistaling agent change the being forced property of antistaling agent and the fruit surface way of contact into by swimming in the fruit surface way of contact naturally; Fully improve probability that antistaling agent contacts with fruit surface and increased contact area; Make antistaling agent enter into the hole skin of fruit surface fully and fully contact with the fruit cell tissue, the antistaling agent functioning efficiency is improved; The 3rd; Because being forced property of antistaling agent contacts with fruit surface; Cross low or contact insufficient antistaling agent effect that makes because of temperature when having avoided antistaling agent to handle and can not get fully playing shortcoming with fruit; Compare with the Preservation Treatment time of volatilizing naturally, shorten the processing time more than 50%, improved production efficiency; The 4th, use this method to carry out simultaneously with the fast precooling sport technique segment of fruits and vegetables, shorten the cold chain commercialization place time more than 50%, both fruits and vegetables had been carried out precooling, carried out the antistaling agent processing again, improved speed of production.
