Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a grinding device suitable for producing monolithic parts of common C2-moisture-rich food raw materials such as vegetables.

[Prior art and its problems] So-called strained vegetables, which are made by grinding vegetables such as carrots, pumpkins, and corn, are added to various foods as nutritional foods, or used as a stimulant ingredient in breads, etc. A wide range of applications have been proposed. To grind such vegetables, a grinding device such as a stone mill is generally used because it is possible to obtain ground products with a desired particle size. However, when grinding with such a grinding device, the temperature of the ground product rises due to the generation of frictional heat during quartering, resulting in an optimum temperature range (30 to 50 degrees Celsius) that increases the growth of microorganisms. Foods with a high water content, such as these, have a significant growth of microorganisms, and due to this strictness, the products are often judged to be defective by bacterial testing. For this reason, the current situation is that after grinding, heat sterilization is performed either directly or after packaging using a separately installed light heat sterilizer. However, even such a method does not inhibit the growth of bacteria in the grinder, but rather sterilizes the bacteria after they have multiplied. Therefore, it does not actually inhibit the growth of microorganisms, and it is necessary to immediately feed the sterilizer into a separately installed sterilizer, which only makes the work more complicated. No, M1
It is necessary to control the heating temperature and time to ensure the effectiveness of sterilization in the machine.

On the other hand, in order to suppress the temperature rise during grinding, a method has been proposed in which the raw material is cooled to the lowest possible temperature in advance, but in this case, cooling with water increases the moisture content of foods with a high water content such as vegetables. Therefore, a method of quenching using an expensive low-temperature liquefied gas such as liquefied nitrogen C (boiling point -196°C) is convenient, but it is of course expensive as mentioned above. There was an inconvenience that a large amount of heat was required for steaming during cooking, resulting in a cine economy.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and its purpose is to separate vegetables with a high water content. T1 crushing device that prevents the growth of microorganisms without using a double-heat sterilizer, and simultaneously performs sterilization and cooking to achieve the same product yield and reduce the grinding processing cost. To provide 1
-Yes.

[Structure of the Invention] The grinding device of the present invention includes a grinding mortar for grinding food raw materials, a hopper for supplying the food raw materials to the grinding mortar, and a hopper (1) for heating the food raw materials, respectively. In order to do this, a heating steam pipe is installed to inject steam.
