After that, add water W and pressurize. In this device, the high pressure vessel is fixed. Further, the rear lid 03 is not opened or closed during use, and only the front lid 02 is opened or closed, and the objects to be processed are transported in and out only from the front side.

[Problem to be solved by the invention]

In conventional high-pressure processing apparatuses, the objects to be processed are carried in and out from one end of the cylindrical container, which hinders improvement in work efficiency.

Furthermore, since the structure was such that a heavy yoke frame was moved laterally, the device as a whole became large and required a large installation area.

The present invention has a structure in which the lids at both ends of a high-pressure container can be opened and closed to improve work efficiency during loading and unloading, and also has a structure in which a heavy yoke frame is fixed and a lighter high-pressure container can be moved vertically. The aim is to downsize and reduce the installation area.

[Means for Solving the Problems] The present invention solves the above problems and relates to a high-pressure processing apparatus having the following features.

(1) In a cylindrical high-pressure container that is installed horizontally within a yoke frame and has lids closed at both ends, food, medicine, and other objects sealed with a flexible film are pressure-processed. The high-pressure processing apparatus is provided with means for opening both lids at both ends of the high-pressure container when carrying in and out of the object to be processed.

(2) In the high-pressure processing apparatus of the preceding item, means is provided for moving the high-pressure container in the vertical direction while keeping the yoke frame fixed when carrying in and out of the object to be processed.

[Effect]

(1) In the apparatus of the present invention, both lids at both ends of the cylindrical high-pressure container are opened, the direction of transfer of the processed material is made unidirectional, and the material to be processed is carried in from one end and taken out from the other end. Do this at the same time. This makes it possible to improve the efficiency of loading and unloading operations.

(2) In the apparatus of the present invention, the high-pressure container is moved vertically when carrying in and out of the workpiece, and the transfer path of the workpiece is not obstructed by equipment such as a yoke frame.
The materials to be processed are transported in and out. Since this device moves the container vertically, it can be made more compact compared to conventional devices that move a heavy yoke frame. Since no extra floor space is required, the footprint can be reduced compared to conventional devices for laterally moving the yoke frame.

〔Example〕

FIG. 1 is a front view (partially shown in cross section) of an embodiment of the high-pressure processing apparatus of the present invention, and FIG. 2 is a plan view of the same embodiment. In the figure, 1 is a cylindrical high pressure vessel. In this device, as shown in the plan view (Fig. 2),

Also, IX is the raised position of the high-pressure container, and D is the horizontal movement of the same container.

Use this device in the following order: First, the container lifting device 7 is operated to raise the high pressure container l to its raised position IX. Next, the workpiece P is carried in.

The container lifting device 7 is operated again to lower the high pressure container 1. Next, the container 1 is moved horizontally by a distance and inserted into the fixed rear lid 5. Next, the water supply cover ring 3 is advanced. As a result, the container 1 is sealed to the extent that normal pressure water does not leak, so there is a water supply and drainage port 1 in the container.
Water is poured in through the overflow port 11, and air and overflow water are discharged through the overflow port 11.

After the water becomes full, the front lid 2 is moved forward by a hydraulic cylinder 4. The water supply/drainage port 10 and the overflow port 11 are closed by the side surface of the front lid 2, and the container 1 is in a sealed state so as to be able to withstand high pressure water. Thereafter, pressurized water is sent through the adjustment eye 12 using a high-pressure pump to increase the pressure inside the container 1. The boosted state is maintained for a predetermined period of time. During this time, processes such as processing and sterilization of the object P proceed in the container 1.

After processing and spinning, the pressure inside the container 1 is reduced through the pressurizing port 12. The front cover 2 is moved back by the hydraulic cylinder 4, and the water supply and drainage port 10 is opened.
The overflow port 11 is opened, air is let in from the overflow port, and water is drained from the water supply and drainage port. The water supply cover ring 3 is moved backward, the high-pressure container 1 is moved a distance and removed from the rear lid 5, and the container is raised by the container lifting device 7 to its raised position IX. The object to be processed P is carried out from the container end on the carrying-out side opposite to the carrying-in side using the carrying-out conveyor 9 to complete one process. The workpiece P for the next step can be carried in from the carrying-in side container end simultaneously with the above-mentioned carrying out. This device has (A

Reference numeral 23 indicates a control device of the present device, but detailed wiring of signal lines and the like are omitted.

FIG. 4 is a plan view of various examples of the device for distribution of loading and unloading sides when using this device, (a), (b
) and (c) are shown.

The most efficient method can be selected and adopted from among these loading/unloading devices depending on the conditions around the processing equipment installation location and the status of the preceding process. In the figure, 24 is a device assigned to the carry-in side, and 25 is a device assigned to the output side.

(a) The workpieces P sent from one direction are stopped at the center of the device 24, and are aligned at a 90° horizontal shear to the side of the high-pressure container that is not pressurized. After arranging the items so that they can be easily transported into the container, carry them in. At the same time, the processed workpieces P are sent out to the carry-out device 25, aligned, and then 90° horizontally sheared and loaded onto the carry-out device and carried out. On the other hand, when the above operation is completed and the container is lowered and the other treated container is raised, the same operation is performed on that high pressure container. By repeating this process alternately, highly productive loading/unloading can be achieved.

(b) This is an example equipped with a device that distributes the flow of the processed material to the processed material transport cart for each high-pressure container by slightly changing the angle.

(C) This is an example in which a device is installed on the carry-in side and the carry-out side where the material to be processed flows in a direction perpendicular to the high-pressure container, and the material is carried into and taken out of each high-pressure container.

As detailed above, in the high-pressure processing apparatus of this embodiment, since the lids at both ends of the high-pressure container can be opened and closed, it is possible to unify the movement direction of the flow of the processed material during loading and unloading. In addition to improving work efficiency, the yoke frame is fixed,
Since the structure is such that a relatively lightweight high-pressure container is raised and lowered, the equipment for each high-pressure container is downsized and the installation area is reduced. Therefore, by alternately operating the two as a pair, it is possible to improve the -layer work efficiency.

[Effects of the Invention] In the high-pressure processing apparatus of the present invention, by providing means for opening both lids at both ends of the high-pressure container when carrying in and out of the to-be-processed objects, the efficiency of the work of carrying in and out of the to-be-processed objects is improved. can be improved. Alternatively, by further providing means for moving the high-pressure container in the vertical direction while keeping the yoke frame fixed when carrying in and out of the processing object, the apparatus can be downsized and the installation area can be reduced.
