BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water disinfection apparatus for disinfection by heating with hot water.

[0002]

2. Description of the Related Art When a container containing gelatin and contents having a specific gravity higher than that of gelatin is sterilized by heating with a hot water sterilizer, the viscosity decreases when gelatin is heated, and the contents are reduced due to gravity. Because the product value is low if it gathers at the bottom and is cooled and solidified as it is, a large number of pack containers placed on trays are stored in the framework provided in the pressure vessel, and during the cooling process after heat sterilization, By cooling while rotating the entire frame, the contents in the gelatin in the pack container are scattered as a whole. However, when rotating the framework, the contents are often unevenly distributed in a part of the pack container due to the inertial force due to the rotation and are not evenly distributed.

[0003]

The problem to be solved by the present invention is that when a gelatinous container and contents having a specific gravity higher than that of gelatin are put into a pack container and sterilized by heating and cooled, the contents harden while being unevenly distributed. It is an object of the present invention to provide a hot water disinfection apparatus capable of preventing the occurrence of a problem and producing a product in which contents are dispersed in a container.

[0004]

Means for Solving the Problems A framework for accommodating a pack container inside a cylindrical container to be subjected to heat sterilization, a rotating shaft provided at an end of the framework of the central axis portion of the cylindrical container, and the rotating shaft is driven outside the container. Connected to the device, the drive device is connected to an electric motor that can not only forward rotation but also reverse rotation, is a hot water type sterilization device that rotates the rotating shaft by operating the motor and rotates the framework, Two sensors that detect the rotation of the rotation axis by detecting the position of the position designation bar and the position designation bar on the rotation axis that is outside the container are point symmetric about the rotation axis
At the position of , receiving the signal from the sensor, inverting the rotation direction of the framework, and
A control device provided for controlling the operation of the electric motor so that is a constant point, alternately switching the rotation direction of the motor to forward rotation and reverse rotation during the cooling, the contents are biased by changing the rotational direction of the framework To stop the rotation of the framework

[0005]

[Function] When the rotation direction of the framework is changed by alternately switching the rotation of the electric motor between forward rotation and reverse rotation, the inertia force acting on the contents in the pack container is reversed each time the rotation direction is switched. It works in the direction and the inside of the pack container is stirred, so that the contents are dispersed without bias. Also,
