[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure steaming apparatus suitable for pressure steaming soybeans in the production process of boiled beans, miso, soy sauce, natto, etc.

0002

BACKGROUND OF THE INVENTION Conventionally, the structure of the lid of a steamer has been either an Astoria type (clutch type) opening/closing type or an eye bolt type lid. Examples of the configuration are shown in FIGS. 8 and 9.

0003

[Problems to be Solved by the Invention] However, in the case of the clutch type, the vise 17 remains on the side of the barrel 16, and when the product is tilted and taken out after steaming, this vise becomes an obstacle, causing the periphery of the vise to There were disadvantages such as product adhesion and unsanitary conditions, and the flange width was large and the O-ring for sealing was easy to separate.

In addition, in the case of an eye bolt fixing lid, the eye bolt 19 remains on the body 18 side, and when the product is taken out after processing, the eye bolt dangles, which is dangerous and poses a sanitary problem. It had drawbacks such as being easy to come off. The purpose of the present invention is to solve the above-mentioned difficulties, to attach an air-lock type packing to the lid side, to make it easy to open and close the lid, and to greatly extend the life of the packing, and to prevent the product from being damaged after heat treatment. It is an object of the present invention to provide a pressure steaming apparatus which can be handled easily and hygienically by tilting the steaming pot even when taking out the steaming pot.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a lid that covers an opening of a steaming pot, a shaft supporting the steaming pot in a tiltable manner, and an opening of the steaming pot. A body flange provided on the periphery, an air lock packing attached to a lid flange facing the body flange, and a ring-shaped vise split into two, one of which is connected to the lid flange and the other to the body flange. It consists of a half-claw type vise that is provided to clamp the body flange and the lid flange from the outside at the matching position, a lid sliding part that slides the lid, and a lid drive part that opens and closes the lid. It was used as a pressure steaming device.

[0006] Also, in the second invention, the lid covering the opening of the steaming pot is pressurized so that the lid slides once in the horizontal direction by the lid sliding part and then moves upward by the lid driving part to open the lid. It was used as a steaming device.

[0007]

[Function] In the first invention, since the lid is equipped with an air lock type packing on the lid flange side opposite to the body flange provided at the periphery of the opening of the steamer, when the lid is tightened, air pressure is applied from the back side of the packing. It is now possible to seal. Therefore, compared to the conventional case in which the packing is sealed by mechanical tightening, the precision in manufacturing the lid is relaxed, and the packing is not deformed due to compression or heating. In addition, since the packing is attached to the lid flange side, there is no obstacle when opening and tilting the lid to take out the product after processing, making it easy to clean and opening and closing the lid.

[0008]Furthermore, since the vise that is attached and detached to clamp the body flange and the lid flange from the outside is a half-claw type vise, one of the halves can move with the lid so as not to become an obstacle when opening and closing the lid. can. In the second invention, when the lid is opened, the lid is moved horizontally by the lid sliding part and then moved upward by the lid driving part, so that the packing attached to the lid flange side is removed when the lid is opened. This prevents it from coming off or sticking to the body flange, allowing for smooth opening and closing of the lid.

[0009]

[Embodiment] The following is an explanation based on the drawings shown as an embodiment. Figure 1 is a front view of the steamer, Figure 2 shows the lid when it is sliding,
Figure 3 shows the case where the steamer is tilted. Reference numeral 1 denotes a steaming pot, which is supported by a shaft support 2 so as to be tiltable. Reference numeral 3 denotes a body flange, which is provided around the opening of the steamer 1. A lid 4 covers the opening of the steamer 1. 5 is the lid flange,
An air lock type packing 6 is installed at the periphery of the lid 4 and facing the body flange 3 (see FIG. 5).
.

In FIGS. 4 and 5, reference numeral 7 denotes a half-claw vise, which is attached and detached so as to clamp the body flange 3 and the lid flange 5 from the outside. Although this half-claw type vise is not shown, it is a ring-shaped vise that is split into two at the periphery of the opening of the steamer 1, and one of the two halves is attached to the lid flange 5, and the other to the body. It is connected to flange 3. When the lid 4 slides in the horizontal direction by the lid sliding part 8 when opening or closing the lid, one vice 7 coupled to the lid 4 slides together with the lid 4 and closes the opening of the steamer 1. It is provided so as to sandwich the lid flange 5 and the body flange 3 when the lids are aligned with each other. Also, when the lid is opened, one half of the vise moves with the lid flange, so
When the steamer 1 is tilted about 110 degrees and the product is taken out, there is no obstacle at all. Reference numeral 9 denotes a lid driving portion which opens and closes the lid 4 by rotating upward and rising. In the case of FIG. 1, a balance weight 10 and an auxiliary air or hydraulic cylinder 11 are provided, but in FIG. 2 as another embodiment, only the balance weight is used.

FIG. 5 shows a state in which the body flange 3 and the lid flange 5 are sandwiched, and an air lock type packing 6 is loaded on the lid flange 5 side. By pressing the packing 6 against the body flange 3 side using air pressure in this way,
The manufacturing precision of the body flange 3 and the lid flange 5 is relaxed, and the operation when opening and closing the lid 4 is facilitated, so that the packing 6 is not deformed by tightening pressure, etc., or fused to the body flange side under high temperature and high pressure. lost.

FIGS. 6 and 7 are detailed views of the lid sliding portion 8, in which 12 is an air or hydraulic cylinder, 13 is a sliding shaft that drives the lid 4 to slide horizontally. There is. Guide shafts 14 and 15 are supported so as to guide the sliding movement of the lid 4.

[0013]

Effects of the Invention In the first aspect of the present invention, the lid covering the opening of the steamer is provided with a lid flange facing the body flange, and the air lock type packing is loaded on the lid flange side, so that the lid can be closed easily. Afterwards, it became possible to easily seal the packing by pressing the packing with air pressure, and it became possible to loosen the precision in manufacturing the lid flange and the body flange. In addition, when opening the lid, the air pressure of the air lock type packing inside the lid flange is stopped and the air is released to allow the lid to slide, but there are drawbacks such as the packing sticking to the body flange and deforming the packing when opening the lid. has definitely been resolved. The half-claw vise that clamps the body flange and lid flange from the outside is separated from the half, so when the steamer is tilted about 110 degrees to take out the product after processing,
It does not become an obstacle, and since the body flange has a smooth surface, cleaning is easy and sanitary.

[0014] In the second invention, when opening the lid, by first sliding the lid in the horizontal direction and then moving it in the vertical direction, the half-claw type vise is smoothly separated from the half-split part, and the packing is separated. Horizontal movement without putting any strain on the seal creates shearing force on the seal surface, making it easier to separate. In addition, since the packing has two contact points, the life of the packing can be maintained for a long time, and the tilting of the steamer eliminates the problem of a vise becoming an obstacle when taking out the processed product. It became so.
