[Problems to be solved by the device]

Generally, food processing plants have a low building, do not have an overhead crane, etc., and often have a low floor bearing capacity. By the way, in the conventional device, since the vertical axis of the cylindrical container is a so-called vertical type, if the height of the building is insufficient, it is necessary to dig a pit and install it in the However, there is a problem in that it is not easy to carry the product and to handle it in and out of the cylindrical container. Also, a high-pressure cylindrical container is generally heavy,
If it is a vertical type, the floor load per unit area is also large, and it is necessary to enhance its bearing capacity. It is necessary to make the cylindrical container large in order to increase the amount of treatment at one time, and if the diameter is increased, the thickness increases and the rate of increase in weight increases, so
It is desirable to lengthen it in the axial direction. However, in the vertical type, it is difficult to increase the size of the cylindrical container in the axial direction because of the disadvantages described above.

The present invention is intended to provide a new high-pressure processing apparatus that solves the above-mentioned problems.

[Means for Solving the Problems]

Therefore, the high-pressure processing apparatus of the present invention includes a cylindrical container, a lid attached to each end of the cylindrical container, a cylindrical container for accommodating the cylindrical container and supporting an internal pressure axial force of the cylindrical container acting on both the lids. In a hydrostatic pressure device including a window frame-shaped yoke frame, the cylindrical container is installed such that its axis is in the horizontal direction, and lids attached to both ends of the cylindrical container are an opening lid and a fixed lid. The window frame-shaped yoke frame slides horizontally between the position supporting the axial pressure of the internal pressure of the cylindrical container (pressurizing position) and the standby position with the end on the fixed lid side as the center. It is configured so that it can be rotated dynamically, and its rotation center point is located at the corner portion between the side surface of the window frame on the side opposite to the rotation side of the yoke frame and the window frame surface on the side of the rotation center point from the axial center of the cylindrical container, or Also characterized by being placed outside A.

[Action]

The above-described high-pressure processing apparatus of the present invention opens and closes the lid on one end of the cylindrical container on the floor during high-pressure cooking of the object to be processed,
The object to be treated is put in and out of the cylindrical container on the floor to facilitate its operation.

When the yoke frame is in a position (pressurizing position) that supports the axial pressure of the internal pressure of the cylindrical container when putting it in and out of the cylindrical container for high-pressure cooking of the object to be processed, When the window frame surface is brought into close contact with the end surface of the fixed lid and the yoke frame is rotated and moved to the standby position, the window frame surface is gradually separated from the end surface of the fixed lid according to this rotation.

Further, when the yoke frame is rotated and moved from the standby position to the pressurizing position, the window frame surface gradually approaches and comes into close contact with the end surface of the fixed lid due to this rotation.

FIG. 1 is a plan view, FIG. 2 is a side view, FIG. 3 is a front view, and FIG. 3 is a sectional view taken along line IV-IV in FIG. 3, in which 1 is a cylindrical container, which is installed on the lower support 6 and the upper supports 7, 8a, 8b, 8c with the axis L thereof in the horizontal direction, A lid 2 is fitted on one end, and a hydraulic cylinder type pressurizing device 3 also serving as a fixed lid and a piston 3a thereof are mounted on the other end. Reference numeral 4 denotes a container for accommodating the object to be processed P, which is placed on the roller conveyor 1a mounted in the cylindrical container 1. Reference numeral 5 denotes a yoke frame, which is erected so as to rotate by sliding on a slide base 10 by a hydraulic cylinder 9 about a rotation center point C, and a substantially window frame-shaped space in the space. A cylindrical container 1, a lid 2 and a pressure device 3 are housed.
The rotation center point C is arranged so as to be offset from the axis L by the distance L between the axis L and the counter-rotation side window frame side surface of the yoke frame 5 and the corner portion 5a of the rotation center point side window frame surface. ing. Reference numeral 11 is a hinge, which is attached to the lid 2, and its guide hole is attached to a guide rod 12 fixed to the cylindrical container 1 and a hydraulic cylinder.

Reference numeral 21 denotes a carrier, which is mounted on the rail 20 and has a roller conveyor 21a mounted on the upper surface thereof.

Next, the operation of this device will be described.

First, the yoke frame 5 is rotated about the rotation center point C by the hydraulic cylinder 9 and moved to the standby position X.

At this time, since the rotation center point C is displaced from the axis L by the distance a, the anti-rotation side window frame side surface of the yoke frame 5 and the corner portion 5a of the rotation center point side window frame surface move in this rotation. Therefore, the end surface of the pressure device 3 is not gradually separated from the end surface of the pressure device 3 and is not pressed during the rotation. Further, since the gap b is also formed between the corner portion 5b of the window frame surface on the side of the counter rotation center point and the lid 2, it does not come into contact with the end surface of the lid 2 during the rotation. Next, the hinge 12 is moved by the hydraulic cylinder 13 to pull out the lid 2 from the cylindrical container 1, and the hinge 12 pivots the lid 2 in the lateral direction. Next, the container 4 containing the object P to be processed is placed on the roller conveyor 21 of the carrier 21 and conveyed to the cylindrical container 1, and the tip of the roller conveyor 21 is connected to the roller conveyor 1a in the cylindrical container 1 to form the container 4. It is stored in the cylindrical container 1. Next, the carrier 21 is separated from the cylindrical container 1 and the lid 2 is removed.
Is closed, and the yoke frame 5 is rotated to return from the standby position X to the pressing device. At this time, the corner portion 5a gradually approaches the end surface of the pressure device 3 according to this rotation, and the window frame surface thereof comes into close contact with the end surface of the pressure device 3. Next, as shown in FIG. 4, the water W is supplied from the water supply port 1b to fill the cylindrical container 1 and the air A is discharged from the exhaust port 1c to connect the water supply port 1b and the exhaust port 1c with a valve (not shown). Then, the piston 3a is moved to the right in the drawing by the hydraulic pressure of the pressurizing device 3 to pressurize the water W in the cylindrical container 1, the lid 2 moves to the right in the drawing, and the gap b is formed. It disappears, and the end surface of the lid 2 comes into close contact with the window frame surface. Then, the piston 3a is moved further to the right in the figure to move the cylindrical container 1
The inside is pressurized to a high pressure such as 4000 kg · f / cm ² , and the object P to be processed is subjected to high pressure cooking. Then, the high-pressure internal pressure axial force acting in the cylindrical container 1 is supported by both window frame surfaces.

When the high-pressure cooking process is completed, the piston 3a is moved to the left in the drawing to reduce the pressure in the cylindrical container 1 to atmospheric pressure, discharge the water W from the water supply port 1b, and remove the lid 2 by the hydraulic cylinder 13. The yoke frame 5 is moved to the left in the figure, a gap b is formed between the end face and the window frame surface of the yoke frame 5, and the yoke frame 5 is rotated to move to the standby position X.

Next, the lid 2 is opened from the cylindrical container 1 by the hydraulic cylinder 13 and by the extraction hinge 11, and the container 4 is pulled out onto the transport vehicle 21.

[Effect of device]
