Integrated multi-mode fruit and vegetable cleaning and fresh-keeping device

Abstract

The invention discloses an integrated multi-mode fruit and vegetable cleaning and fresh-keeping device which comprises a power module, a fruit and vegetable cleaning and fresh-keeping module and a connecting module; a high-voltage electrode plate and a dielectric plate are suspended in a lower reaction cavity in the fruit and vegetable cleaning and fresh-keeping module, and an insulating layer is arranged on the upper surface of an upper reaction cavity; the high-voltage electrode plate comprises a circular high-voltage electrode and a barrier dielectric plate for mounting, fixing and isolating the circular electrode plate; a partition plate is connected in front of the square frame; high-pressure holes, air holes and ground wire holes are formed in the surfaces of the partition plates; a high-voltage wire passing through the high-voltage hole is connected with the circular high-voltage electrode plate; gas passing through the gas holes enters the lower reaction cavity; through holes are formed in corresponding positions of the frame partition plate and the dielectric plate between the upper reaction cavity and the lower reaction cavity, so that gas entering the lower reaction cavity flows out; a ground wire passing through the ground wire hole is connected with the bottom surface of the dielectric plate. The intensity and flow velocity of plasma are easy to adjust, two working modes of fruit and vegetable cleaning and fresh keeping are integrated, and the working modes can be flexibly selected according to application requirements.

Description

technical field [0001] The invention relates to the technical field of fruit and vegetable purification, in particular to an integrated multi-mode fruit and vegetable cleaning and preservation device. Background technique [0002] Fruits and vegetables are widely welcomed by the public because they are rich in nutrients such as a large amount of inorganic salts, microorganisms, minerals and trace elements, and have become an indispensable food for every household. However, fruits and vegetables will inevitably be polluted during the process of planting, picking, transportation and selling, especially the extensive use of pesticides, so that some pesticides will inevitably remain on the surface of fruits and vegetables, and various microorganisms are also one of the sources of surface pollution of fruits and vegetables. When the dirty components on the surface of fruits and vegetables are ingested into the human body, it may cause headaches, diarrhea, coma and other symptoms,...

AI Technical Summary

Problems solved by technology

[0004] Traditional fruit and vegetable cleaning includes clean water, chemical reagents, ultrasonic waves and other cleaning methods to achieve the purpose of cleaning fruits and vegetables; there are the following problems: (1) Clean water cleaning can only remove some large particles of sediment, etc., and cannot remove pesticide residues, bacteria, etc. Harmful substances; (2) There are chemical residues in chemical reagent cleaning, which is harmful to the human body; (3) It is difficult to control the ultrasonic energy during ultrasonic cleaning, and the ideal cleaning effect cannot be achieved

[0005] Traditional fruit and vegetable storage and preservation methods include freezing, air-conditioning, and chemical antiseptic agents to achieve the purpose of freshness preservation; there are the following problems: (1) The method of freezing and air-conditioning preservation requires a large investment, and there are many supporting power equipment and testing equipment, which is difficult to control The shortcomings of mold growth and elimination of residual chemicals; (2) Chemical preservatives have serious drug residues and environmental pollution problems; therefore, a more efficient method of cleaning and preserving fruits and vegetables is needed

[0007] Plasma technology is mainly divided into two types: dry treatment and activated water treatment; dry treatment devices are generally large in size, and are generally only suitable for processing small-volume fruits and vegetables due to the influence of electrode size and structure; activated water treatment Although the processing size of fruits and vegetables has been improved, the existing devices generally need to prepare activated water in advance, and then soak the fruits and vegetables in activated water for treatment, and the operation is more complicated

[0008] The existing fruit and vegetable cleaning and fresh-keeping technology using plasma technology generally only has a single function, or cleaning function or fresh-keeping function, and cannot organically combine the functions of fruit and vegetable cleaning and fresh-keeping at the same time
