Abstract
A method for removing the residual chemicals from agricultural products features that the negative pressure is applied to the agricultural product and the plasma gas or water is used to treat it. Its apparatus is composed of a container, a vacuumizing pump, a gas-liquid mixing pump and a plasma generator. Its advantages are innocuous treating, and no secondary pollution.
Description
The present invention relates to a kind of processing and remain in the method for chemical substance on the agricultural product and used device.
On agricultural, crops comprise in the plantation, cultivation process of vegetables, paddy rice, fruit tree etc., often need fertilising, desinsection, sterilization etc., like this surface of Shou Huo grain, vegetables, melon and fruit and other agricultural byproducts and inner all easy residual a large amount of agrochemicals.These agrochemicals residual, extremely harmful in melon and fruit, vegetables and other agricultural byproducts.Studies show that, these residual chemical some can be carcinogenic, and can bring out many strange diseases, even can cause gene mutation, cause hereditary variation.It not only endangers direct eater, but also can endanger the next generation.Many scientific workers have done a large amount of research work for this reason, but head it off not yet so far.Now general way still is to wash with water or soak melon and fruit, vegetables etc., but this can't thoroughly remove its residual agrochemicals thing at all, especially in the residual chemical of melon and fruit, vegetables inside.
The purpose of this invention is to provide a kind of processing and remain in the method for chemical substance on the agricultural product and used device, it can solve the above-mentioned problems in the prior art.
A kind of processing remains in the method for chemical substance on the agricultural product, it is characterized in that making earlier agricultural product to be under the negative pressure, handles with plasma (orifice) gas or plasma water again.
A kind of processing remains in the used device of chemical substance on the agricultural product, it is characterized in that having a container, and a pipe of this container is connected with vavuum pump, and another pipe is connected with plasma generator or is connected with plasma generator by gas-liquid mixing pump.
Method of the present invention is pure physical method, and it utilizes the 4th attitude plasma (orifice) gas, the water of material will remain in the agricultural product surface and inner agrochemicals has been done harmless treatment, does not produce any residue, waste water and waste gas, non-secondary pollution in the processing procedure.Adopt plant investment expense of the present invention few, operating cost is low.
Below by embodiment and description of drawings the present invention.
Accompanying drawing is an apparatus structure schematic diagram of the present invention.
Embodiment 1
Present embodiment is handled the 10kg apple.The lid of opening container 1 during processing places apple in the container 1, and a pipe of this container 1 is connected with vavuum pump 2, and the outlet with plasma generator 3 is connected on another pipe of this container 1 again.Start vavuum pump 2 pressure in the container 1 is reduced to below the 0.01MP, temperature is a normal temperature.Air enters in this container 1 through the plasma that plasma generator 3 produces.The poisonous agrochemicals of plasma (orifice) gas inside and outside the condition of negative pressure can make apple suffers to decompose, destroy, and innoxious.In the present embodiment, the residual reason of flolimat of apple is 13.5261mg/kg before handling, and is zero (not detecting) after the processing.
Embodiment 2
Present embodiment is handled the 10kg rape, and the method for processing and used device be with embodiment 1, and difference only is that the plasma that produced by plasma generator 3 mixes the generation plasma water with water in gas-liquid mixing pump 4.Plasma generator 3 is connected with container 1 by gas-liquid mixing pump 4, in the gas-liquid mixing pump 4 water is housed.What add in container 1 in this practical embodiment is plasma water.In other words, use plasma water treatment rape in the present embodiment.Before the processing, the parathion-methyl residual quantity of rape is 22.5657mg/kg, handles back parathion-methyl residual quantity and reduces to 0.0018mg/kg.
Embodiment 3
Present embodiment is handled the 10kg peanut, and the method for processing and used device are with embodiment 1, and the DDVP residual quantity of peanut is 0.5mg/kg before handling, and handles back DDVP residual quantity and reduces to＜0.1mg/kg.
Claims (2)
1, a kind of processing remains in the method for chemical substance on the agricultural product, it is characterized in that making earlier agricultural product to be under the negative pressure, handles with plasma (orifice) gas or plasma water again.
2, a kind of processing remains in the used device of chemical substance on the agricultural product, it is characterized in that having a container (1), a pipe of this container (1) is connected with vavuum pump (2), and another pipe is connected with plasma generator (3) or is connected with plasma generator (3) by gas-liquid mixing pump (4).
