Aquatic product vehicle workshop disinfection

Leading: Aquatic products are the earliest areas of market-oriented reform in China. Aquatic products are the collective name for animals, plants and processed products produced by marine and freshwater fisheries. Fresh aquatic products are divided into four categories: fish, shrimp, crab, and shellfish. Fishes include oysters, clams, turtles, cockroaches, groupers, jaundice, left mouth, true oysters, and triplet fish; shrimps are available in Australia. , New Zealand lobster, Taiwan grass shrimp, bamboo shrimp, giant shrimp, shrimp; crab species of Chinese velvet crab, American treasure crab, king crab, crab, crab, etc.; shellfish have Canada trunk, quail , 蚝, 蛤 and so on.

China's export aquatic product processing industry has problems with microorganisms exceeding standards from time to time. Despite the company's adoption of various measures (such as the use of sodium hypochlorite for water disinfection before product freeze processing), it has not been able to solve the problem of excessive microorganisms. This problem has been solved in summer. Especially serious. At present, there are two shortcomings in sodium hypochlorite water disinfection commonly used in the domestic food processing industry. First, due to different levels of raw material contamination of aquatic products and different export microbial indicators, the concentration of sodium hypochlorite water is difficult to control; second, it is difficult to wash due to high concentration of sodium hypochlorite water. Net, causing chlorine pollution.

In recent years, some developed countries in the world have applied ozone disinfection technology to the food industry. In our country, this application technology is constantly being developed. High-concentration ozone water is a broad-spectrum, high-efficiency, and rapid disinfectant (600 to 3,000 times the effect of killing microorganisms), and has the biggest advantage that other disinfectants do not have, namely, it can be reduced to a short time. Oxygen does not leave any harmful secondary pollutants.

The ozone disinfection and sterilization method has the following characteristics compared with the conventional sterilization method:

(1) High efficiency. Ozone disinfection and sterilization is based on air quality coal, without any other auxiliary materials and additives. The body is well-tolerated, thoroughly sterilized, and has a strong function of removing odors such as mildew, sputum, and odor.

(2) High cleanliness. The rapid decomposition of ozone into oxygen is characteristic of ozone as a unique advantage of sterilization. Ozone is generated by using oxygen in the air. During the sterilization process, excess oxygen is combined with oxygen molecules after 30 minutes. There is no residue, which solves the problem of secondary pollution caused by disinfectant disinfection methods, and eliminates the need for Clean again after disinfection.

(3) Convenience. Ozone sterilizers are generally installed in cleanrooms or air purification systems or in sterilization rooms (eg, ozone sterilization cabinets, transfer windows, etc.). According to the sterilizing concentration and time of the verification and verification, the sterilizer is set to open in time and run time, which is convenient to operate and use.

(4) Economicality. Through the comparison of the use and operation of ozone sterilization and sterilization in many pharmaceutical industries and medical and health units, the ozone disinfection method has great economic and social benefits compared with other methods. In the rapid development of today's industry, environmental protection issues are particularly important, and ozone disinfection has avoided secondary pollution from other disinfection methods.

Ozone sterilization is a bacteriolysis-grade method, which is completely bactericidal, has no residue, and has a broad spectrum of sterilization. It can kill bacteria and spores, viruses, fungi, etc., and can destroy botulinum toxin. In addition, O3 also has a strong killing effect on mold. Due to its poor stability, O3 will soon decompose itself into oxygen or a single oxygen atom, and a single oxygen atom can self-assemble into an oxygen molecule without any toxic residues. Therefore, O3 is a non-polluting disinfectant. O3 is a gas, can quickly diffuse into the entire sterilization space, sterilization without dead ends. The traditional methods of sterilization, whether it is ultraviolet or chemical fumigation, have shortcomings such as incompleteness, dead angle, heavy workload, residual pollution, or odor, and may damage human health. If ultraviolet disinfection is used, there is no effect in places where light cannot reach, there are drawbacks such as deterioration, weak penetration, and short service life. There are also deficiencies in chemical fumigation, such as bacteria and viruses that are very resistant to drugs, the bactericidal effect is not obvious.

The ozone sterilization process for aquatic products is mainly divided into two aspects: immersion and spray.
