Technical Field
The utility model relates to a structure and the theory of operation of whey catalytic oxidation device, concretely relates to whey catalytic oxidation processing apparatus.
Background
Whey is green and semitransparent liquid separated after casein is coagulated into curd blocks by fresh milk under the action of rennin, 9 kilograms of whey and 1 kilogram of cheese can be produced by ten kilograms of fresh milk, so that a large amount of whey liquid is produced while cheese is industrially produced, antibiotic and pesticide residues in raw milk can be enriched in the whey liquid, the raw milk cannot be fully dispersed into the cheese due to the fact that the raw milk liquid is generally water-soluble substances, and the whey is treated by spraying powder, so that harmful substances are enriched and higher than the original content of the raw milk, and unqualified products and standard exceeding of the harmful substances are caused. A large amount of organic harmful substances are generated: pesticides, antibiotics and the like, wherein organic harmful substances (pesticides and antibiotics) are required to be timely treated through catalytic oxidation reaction during the deep processing of whey liquid, so that the quality of the whey deep-processed product is ensured to meet the quality requirement.
Pesticides and antibiotics are degraded by biological methods and biochemical methods, the degradation process is generally an oxidation process, for example, ozone, hydrogen peroxide, oxidant and the like are utilized, and the degradation process is common in water treatment and purification production. Because the food limits the additives, ozone and hydrogen peroxide are safe to be used for oxidation reaction, and food-grade ozone and hydrogen peroxide are respectively used for sterilization and disinfection in food processing processes such as bottled drinking water, aseptic milk packaging and the like. The efficiency of ozone and hydrogen peroxide is limited, and an advanced oxidation method is used in actual production: the catalyst is added on the basis of ozone and dioxygen to improve the process effect, and the catalyst can be used for ZnO, Zn, Fe, active carbon and the like in food.
The invention discloses a method for degrading harmful substances in catalytically oxidized whey in order to improve the harmful substances enriched in whey, and solves the quality problem of whey products.
