Description

Technical Field

[0001] The present invention belongs to the technical field of food processing and preservation, and more specifically relates to a dry-wet dual-purpose device and method for continuous plasma treatment of golden pomfret surface sterilization. Background Art

[0002] Golden pomfret refers to products that can be eaten or used in the ocean, and the range is very wide. Most of them refer to marine animals and marine plants. Because of its rich nutrition, it is one of the most common foods on the table. However, far away from coastal areas, it is almost impossible for people to eat high-quality golden pomfret every day, so how to preserve it has become a topic of concern. Golden pomfret itself is not easy to store. Whether it is fish, shrimp or crab, it will die soon after leaving the water. If it is not processed in time, it will emit a peculiar smell. Especially with the rapid development of the current society, the quality of seawater has been greatly polluted. Various types of golden pomfret are very susceptible to contamination by microorganisms or residual fish medicines during their growth. This leads to the subsequent processing, transportation and storage of golden pomfret. The quality cannot be guaranteed, and ultimately leads to the rapid corruption and deterioration of golden pomfret. Modern golden pomfret storage and preservation are mostly carried out by freezing, chemical antiseptic and product drying. Although direct freezing or product drying can inhibit the growth and reproduction of microorganisms to a certain extent, it cannot achieve long-term storage and preservation. However, freezing and drying golden pomfret combined with chemical preservation has serious problems of drug residues and environmental pollution.

[0003] With the development of society, people have higher and higher requirements for food quality and safety. How to store and preserve golden pomfret with high quality and safety has become a problem that must be solved in people's pursuit of seafood delicacy, and it is also an important problem that must be faced by the rapid economic development of golden pomfret in coastal areas. As a rapidly developing food processing and treatment technology, plasma sterilization technology produces a variety of active particles through the collision of high-energy electrons excited in plasma with gas molecules, which can have a strong prevention and control effect on fungal and bacterial diseases, have a certain inhibitory and killing effect on viruses, and can also degrade the residual toxicity of some chemical substances. At the same time, no pollutants are introduced during the plasma treatment process, and the treated food is a completely green and environmentally friendly product. Therefore, how to provide a continuous plasma treatment dry and wet dual-purpose device suitable for golden pomfret surface sterilization, so as to achieve effective sterilization without destroying the quality of golden pomfret, maximize the storage time of golden pomfret, eliminate the fish medicine residue on the surface of golden pomfret to achieve the purpose of high-quality storage of golden pomfret, is a technical problem that needs to be solved urgently by technicians in this field.

[0038] A continuous plasma treatment method suitable for surface sterilization of golden pomfret, the method is implemented based on the above-mentioned scheme device, and specifically comprises the following steps:

[0039] The golden pomfret is placed at the feed inlet of the housing 1, and most of the water on the surface of the golden pomfret is quickly blown off by the first fan 7 through the top high-power fan, and then transported into the housing 1 through the air-permeable conveying mechanism;

[0040] After the golden pomfret treated by the first blower 7 is transported to the inside of the housing 1 by the air-permeable conveying mechanism, it is continuously blown by the plasma blower mechanism as the air-permeable conveying mechanism works;

[0041] The golden pomfret treated by the plasma blower mechanism is transported to the collection bin 13 .

[0042] The working process of this embodiment is as follows:

[0043] S1. Place the golden pomfret on the porous sample introduction table, and uniformly transport the golden pomfret to the drainage bin through the transmission transposition. Most of the water on the surface of the golden pomfret is quickly blown off by the high-power fan on the top. The blown off water is collected in the water storage tank along the waterway. The water storage tank can be connected to the sewage pipe directly to the sewer;

[0044] S2. The drained golden pomfret is transferred to the first layer of the plasma treatment chamber by a conveyor and treated with air plasma blown by a top fan; as the conveyor works, the golden pomfret with the treated upper surface slides down the inclined plate, and the product is flipped by the reverse wheel at the end of the inclined plate and falls on the second layer of the plasma treatment chamber;

[0045] S3. The reverse transmission of the second layer irradiates the salmon with the top air plasma again. At the same time, the air plasma passes through the downwardly inclined output ports on both sides of the processing chamber and irradiates the golden pomfret to process it. When sliding down from the end of the second layer, it is turned over by the reverse wheel at the end;

[0046] S4. In this way, the treated golden pomfret slides into the collection box from the discharge inclined plate at the end of the fifth layer of the plasma treatment chamber. During the whole process, the plasma treatment time of the LCD panel input is 2 minutes, and the input amount of air plasma is 30m3 / min.
