About 130,000 t, account for the 1/3 of Gross World Product, account for about the 40% of world's dehydrated vegetables total volume of trade.In recent years, World of Food industry
It grows rapidly, the situation that supply falls short of demand was once once occurring in dehydrated vegetables, and market has openings is larger.In the processing and preservation of dehydrated vegetables
During, need to carry out desinsection processing to vegetables, traditional disinsection method desinsection is not thorough, can also cause dehydrated vegetables by
Pollution, and can make the loss of the nutritional ingredient of vegetables, cost is excessively high, for this purpose, it is proposed that a kind of freezing of dehydrated vegetables is killed
Worm method.
Invention content
The purpose of the present invention is to provide a kind of frozen insecticide methods of dehydrated vegetables, to solve to carry in above-mentioned background technology
The traditional disinsection method desinsection gone out is not thorough, and can also dehydrated vegetables be caused to be contaminated, and can make the nutritional ingredient of vegetables
Loss, the excessively high problem of cost.
To achieve the above object, the present invention provides the following technical solutions：A kind of frozen insecticide method of dehydrated vegetables, this is de-
The frozen insecticide method of water vegetables includes the following steps：
S1：Feedstock processing：The raw material of dehydrated vegetables are put into centrifuge and are centrifuged, the moisture of vegetable surface is removed；
S2：It vacuumizes：The raw material of treated dehydrated vegetables are put into freezer, freezer is then sealed, to freezer into
Row vacuumize process so that the vacuum degree in freezer reaches -50 and arrives -45pa；
S3：It is filled with inert gas：After the completion of vacuumizing, inert gas is filled with into freezer so that the inertia in freezer
The percentage of gas is 95%-99%；
S4：Precooling：Temperature in freezer is adjusted to -10 to -5 degrees Celsius, pre-coo time is 1-2 days；
S5：Freezing：Temperature in freezer is adjusted to -20 to -15 degrees Celsius, cooling time is 2-3 days, then again will be warm
Degree is adjusted to -30 to -20 degrees Celsius, freezes 3-4 days；
S6：It rises again：After freezing, freezing equipment is closed, is risen again naturally in freezer so that dehydrated vegetables cools down, and takes
Go out dehydrated vegetables.
Preferably, the centrifugation time in the step S1 is 3-5 minutes.
Preferably, it in the step S2, when the raw material of dehydrated vegetables are put into freezer, by the way of suspension, will take off
The raw material of water vegetables are suspended in freezer.
Preferably, the inert gas in the step S3 is nitrogen.
Preferably, the time of rising again in the step S6 is 3-4 days.
Preferably, when dehydrated vegetables is cooled to room temperature in the step S6, you can take out.
Compared with prior art, the beneficial effects of the invention are as follows：A kind of frozen insecticide for dehydrated vegetables that the invention proposes
Method, insecticide efficiency is high, and can play the role of thorough desinsection, including worm's ovum etc., will not be polluted to dehydrated vegetables, at
This is cheap, additionally it is possible to the effective nutritional ingredient for ensureing dehydrated vegetables, it is simple for process, and it is easy to operation.
