を殺菌する気流式殺菌装置が使用されている。(Prior Art) The raw material for powder and granules in the food industry is a natural product, which is always contaminated with microorganisms, and the number of viable bacteria increases during the processing process.
A large number of viable bacteria in the product causes food poisoning and shortens the shelf life of the product. Therefore, sterilization is required at any stage of the manufacturing process. Conventionally, a heat sterilization method has been applied to sterilize powdered or granular materials such as flour, spices, crude drugs, and natural food additives, and steam sterilization, which has a higher sterilization effect than dry sterilization, has been applied. As the sterilizer, an air flow type sterilizer is used that sterilizes harmful bacteria of the granular material by directly contacting the granular material with steam while air-transporting the granular material into a heating sterilization tube. ing. In addition, when the steam is saturated steam, the granular material becomes wet and agglomerates or adheres to the vessel wall. Therefore, it is necessary to use the superheated steam without wet the granular material. An air flow type sterilizer is used to sterilize harmful bacteria.

る。(Problems to be Solved by the Invention) In general, food is accompanied by quality deterioration such as flavor deterioration and nutrient destruction by heat sterilization. In heat sterilization, it is of utmost importance to minimize these deteriorations and ensure the minimum required sterilization of microorganisms. For that purpose, a short-time heat contact treatment by a rapid temperature rise of the granular material and a uniform treatment time for avoiding sterilization spots and quality spots are required. In particular, when sterilizing a small amount of many types of raw materials for granules, it is required to finely control the sterilization conditions for each product type. Difficult to control. That is, in the air flow type sterilizer, since the powdery or granular material is conveyed by the airflow, the heat transfer coefficient from the airflow to the powdery or granular material is relatively small. Moreover, if the residence time of the granular material is changed with respect to the air flow, the flow velocity of the air flow must be changed or the length of the heating sterilization tube must be adjusted.
It is difficult to delicately limit the sterilization conditions for each product type.
