TECHNICAL FIELD
[0001] The utility model relates to a compound freeze-drying production equipment technical field, specifically relates to a mixing machine with sterilization function. BACKGROUND
[0002] Meat compound freeze-drying (Lyophilization of Formulated Products) is a process that mixes meat with other ingredients (such as adjuvants, stabilizers, flavorings, etc.) and then prepares solid powder or block through freeze-drying technology. This technology is widely used in the food industry, which can effectively maintain the nutritional ingredients, flavor and texture of meat, and prolong the shelf life of the product.
[0003] Compound freeze-drying mixer is a device specially used for compounding and mixing raw materials before freeze-drying. This device is widely used in the drying and storage of food such as chicken, pork and other meat products, which can ensure the uniform mixing and compounding of raw materials and provide high-quality raw materials for the subsequent freeze-drying process.
[0004] Currently, the existing compound freeze-drying production process is: raw material conditioning - raw material crushing - raw material mixing - material forming - material freezing - material freeze-drying - finished product selection - finished product packaging - irradiation sterilization - delivery. In the existing process, the product cannot be sterilized before packaging, and can only be sterilized by irradiation after packaging. However, using this sterilization process, the shelf life of the product will be shortened after sterilization, and there will be abnormal changes in the flavor of the freeze-dried product in the short term.
[0005] Ozone is commonly used for sterilization in the food industry, such as the Codex Alimentarius Commission (CAC) and other relevant regulations or standards that ozone can be used for food processing. In the compound freeze-drying mixer, there is no application of ozone sterilization. UTILITY MODEL CONTENT
