Apparatus for removing pesticide residues on surfaces of vegetables and fruits

Abstract

The invention relates to an apparatus for removing pesticide residues, and especially relates to an apparatus for removing pesticide residues on the surfaces of vegetables and fruits. A switch is powered on, a water stopping valve is opened, tap water enters from a water inlet, NaCl and edible vinegar are respectively added through a NaCl inlet and an edible vinegar inlet, a pressure pump is pressurized to increase the flow velocity and generate a negative pressure, extraneous air is sucked due to sudden narrowing of a water injection tube, air and water are mixed, a motor is started to drive blades on a rotating shaft to rotate, the obtained mixed solution is in full contact with air, a ratio of air to water of the air and water mixed solution is 1:1, the obtained mixed solution enters an outlet water pool through a water outlet tube, and water enters a center, and is sprayed to surfaces of vegetables and fruits through extruding two ends of a water impeller in order to generate nanometer bubbles. The apparatus has the advantages of good pesticide residue removal effect, high removal rate reaching 99.7% or above, no destroys to vitamins of the vegetables or fruits, mouthfeel guaranteeing, suitableness for the fruits and vegetables, and compatibility.

Description

technical field [0001] The invention relates to a device for removing pesticide residues, in particular to a device for removing pesticide residues on the surface of vegetables and fruits Background technique [0002] As we all know, the harm of pesticide residues contained in vegetables, fruits and related products to the human body has attracted more and more attention from the world. Many documents have been issued in my country, requiring strict control of the use of pesticides and the amount of pesticide residues in vegetables, fruits and vegetables. , in order to protect the health of the people, but some businesses are driven by interests, and this problem has not been well handled. [0003] In order to solve the problem of pesticide residues in fruits and vegetables, people currently soak fruits and vegetables for 20-30 minutes when eating, but it is not suitable for some fruits, such as strawberries, soaking for a long time, the taste will change, and eating by peeli...

AI Technical Summary

Problems solved by technology

[0004] The main technical problem to be solved by the present invention is to solve the problems that the pesticide residues cannot be removed by using pesticide remover by soaking, the taste of vegetables and fruits will become worse after the pesticide residues are removed, the nutrients will be lost, and the problem that it cannot be applied to vegetables and fruits at the same time is provided. A device for removing pesticide residues on the surface of vegetables and fruits. The method can efficiently remove pesticide residues on the surface of vegetables and fruits through nano-bubble washing, vinegar and salt disinfection, and at the same time does not destroy the vitamins of vegetables and fruits to ensure their taste.
