Description

  The present invention relates to a liquid product preparation method and a liquid product continuous preparation machine used in the liquid product preparation method.

In general, the manufacture of dairy products and soft drink products begins with blending multiple types of ingredients. For example, processed milk is a product in which butter, cream, skim milk, water, etc. are formulated, and soft drinks, juices, etc. are prepared from raw materials such as granulated sugar, liquid sugar, concentrated fruit juice, stabilizer, water, etc. Manufactured.
Conventionally, preparation of each main raw material in manufacturing such a liquid product is performed by batch processing, and a plurality of types of raw materials are prepared in a tank and supplied to the next sterilization step.

  As shown in FIG. 5, in such a batch processing step 70, for example, the main raw material 72 and the auxiliary raw material 73 are prepared in the preparation tank 74 in the preparation step D, and then sterilized in the sterilization step E, and the surge tank. The filling process F is performed through the process 76.

  However, in order to perform such batch processing continuously, two mixing tanks 74 and a surge tank 76 are required, and the mixing piping connected to the mixing tank 74 is complicated, and as a whole There is a problem that the installation cost increases and the cleaning cost and various energy costs increase.

  Therefore, in order to solve such problems, a liquid continuous blending process 80 using a liquid continuous blender has been proposed. In the liquid continuous preparation step 80, for example, in the continuous preparation step G, the main raw material 81 and the auxiliary raw material 82 are continuously prepared by the liquid continuous preparation machine 83, and then sterilized in the sterilization step H, and the cushion tank 84 is installed. And filling in the filling step I (Patent Document 1).

  According to such a liquid continuous blending process 80, the problems in the conventional batch processing process 70 can be solved, the number of blending tanks can be reduced, the blending pipe can be simplified, the installation area can be reduced, the cleaning cost and the energy cost. Can be reduced.

  However, in such a liquid continuous preparation process 80, after the main raw material 81 and the auxiliary raw material 82 were prepared in the continuous preparation process G, it was configured to sterilize in the sterilization process H. The size of the sterilization equipment used has become large, and there has been a demand for further downsizing of the equipment from the viewpoint of saving space and reducing cleaning costs.

Moreover, in such a liquid continuous preparation process 80, since the main raw material 81 and the auxiliary | assistant raw material 82 are prepared in the said continuous preparation process G, and it sterilizes in the sterilization process H, it is the optimal temperature conditions for each raw material. In some cases, the liquid product could not be sterilized and good quality of the liquid product could not be ensured.
Furthermore, conventionally, after each raw material has been sterilized, it has not been mixed aseptically. This is because it is necessary to maintain the sterility by further cooling or heat-treating the sterilized raw material, so that an apparatus for performing inert gas filling and pressurizing treatment is required, and the equipment cost increases, and the production equipment This is because the installation space for the apparatus increases due to the increase in size as a whole.
Therefore, since each raw material was mixed in a non-sterile state after the sterilization treatment, there was a problem that the product life of the manufactured liquid product was short.
