Background
The following sterilization equipment modes are commonly used in China: microwave sterilization, high-temperature thermal sterilization, steam sterilization, cooking sterilization and the like, wherein the most common mode is a high-temperature thermal sterilization mode, and the mode kills the number of bacteria in the product through high temperature so as to meet the customer standard. Typical equipment comprises a cooking sterilizer, a sterilizing kettle, a tube array or a sleeve type sterilizer, and the equipment is divided into the following parts according to different sterilization modes: the ultra-high pressure sterilization method, the low pressure sterilization method, the pasteurization method, the microwave sterilization method, the ultraviolet sterilization method, the ozone sterilization method, the membrane filtration method, the chemical sterilization method and the like have good sterilization effects. New technology for sterilization is also being developed and used gradually, such as: resistance heating sterilization technology, far infrared sterilization technology, pulse strong light sterilization technology and the like.
The food sterilization technology and theory are deeply applied to various industries, the production process control or personnel disinfection and sterilization have the figure of the sterilization technology, the food sterilization technology is particularly prominent in the food production and processing industries of agricultural products, aquatic products and the like, and the food sterilization technology is an important means for ensuring the food safety and the product quality. Once the sterilization is incomplete, the product is scrapped if the sterilization is not complete, and the whole production line is polluted if the sterilization is complete. Because agricultural products, aquatic products and the like are various in variety, and various product characteristics and processing requirements are different, the sterilization mode is determined to be correspondingly adjusted according to specific product characteristics.
The sterilization of agricultural products, aquatic products and other foods is mostly high-temperature thermal sterilization, low-temperature sterilization, pasteurization, chemical method and the like. Most of the raw materials are processed in a liquid environment, and the sterilization in a solid dry state has the defects of incomplete sterilization, high energy consumption, poor color and luster of products due to Maillard reaction and the like. For example, patent document CN113133483A discloses a method for producing yogurt by using an ohmic sterilization process, which replaces the conventional heat exchange sterilization process of a tubular or plate type sterilization machine. The invention solves the problems of high sterilization strength, long heating time, poor stability, high addition amount of the stabilizer and the like caused by the traditional sterilization mode after fermentation. The heat treatment strength is reduced on the premise of ensuring the food safety. For example, patent document CN113016876A discloses a process for improving ultra-high pressure sterilization effect and fresh milk, wherein a bacteriostatic agent is added into fresh milk, and then at least three times of ultra-high pressure sterilization are performed, which sequentially comprises primary sterilization treatment and advanced sterilization treatment. The treatment temperature is maintained at 4-65 ℃, the product quality can be better ensured, microorganisms, particularly spores with strong high pressure resistance can be thoroughly killed, active ingredients such as the furosine, the beta-lactoglobulin, the IgG and the like are furthest reserved, and the shelf life is prolonged. For example, patent document cn201811448158.x discloses a sterilization process for large-particle jam, wherein the processed material is the jam containing granular substances, and the jam is sterilized by a rotor pump, a mixing tank, a screw pump and a coil type sterilization machine. The temperature is controlled at 95-125 ℃, the jam damage rate is reduced to the maximum extent while the thorough sterilization of the jam is ensured, and the texture, the taste, the color and the nutritional value of the product are retained to the maximum extent.
However, the materials of the sterilization method are all liquid wet high-temperature sterilization, the precision requirement of the equipment is high, and the energy consumption is high. The invention aims to use a dry sterilization and bleaching process for processing particles or powder and matched equipment thereof to achieve a method for directly treating dry particles or powder bacteria, thereby not only realizing continuous production, but also reducing energy consumption.

Compared with the prior art, the invention has the beneficial effects that:
1. the invention utilizes a composite dry sterilization mode combining a certain temperature and time (preferably 65-75 ℃ and 15-30 minutes) with a small amount of oxidation bactericide, has mild sterilization method and simple and controllable equipment and operation process, and is completely different from the common wet-heat sterilization method (generally boiling at about 100 ℃ for 2-6 hours). The wet heat sterilization method uses high-temperature and high-pressure steam as a medium, and because the latent heat of the steam is large, the penetrating power is strong, the protein is easy to denature or solidify, and finally the microorganism is killed, the sterilization efficiency of the method is higher than that of the dry heat sterilization method, and the method is the most commonly used sterilization method in the production process of pharmaceutical preparations.

2. The invention is also different from the existing dry heat sterilization method of materials, which is a technology for killing bacteria and bacterial spores at high temperature in a dry environment and is used for articles which cannot tolerate damp and hot steam and cannot be sterilized by high-pressure steam. The dry heat sterilization method needs higher temperature and longer time. A usual temperature is 160 ℃ for 2 h. The dry heat has great damage to some heat-labile materials, and is not suitable for application. The invention is just suitable for sterilizing heat-sensitive substances, has continuous production and good sealing property, and is suitable for heating, sterilizing, bleaching and the like of various particles and powder.
3. The equipment of the invention is convenient to clean and wash, thorough in sterilization and low in temperature control. The traditional sterilization machine cannot play a good sterilization role on large granular substances, can cause materials to brown, and can ensure whiteness of the materials while ensuring sterilization of the granules. The quality loss of the product is reduced as much as possible.
The invention has wide operation range, adjustable temperature and oxidant consumption, and uniform and easily controlled jacket heating. The jacket is heated to a certain temperature and then is insulated, and a small amount of bactericide and substances can be added and fully mixed to achieve the effects of sterilization and bleaching.
