Description

[Detailed Description of the Invention] The present invention relates to a coagulated soymilk dehydration press device used when coagulated soymilk is packed in a mold box and then dehydrated and pressed in a tofu manufacturing process.

Initially, the method of dehydrating coagulated soymilk placed in a mold box was to place a suitably sized weight on the lid of the mold box. The method used is to use a lever from above to hold down a bundled pillar placed in the center.

Another method is to use a pneumatically or hydraulically operated piston in a cylinder that moves vertically from above the lid of the mold box to perform a dewatering press.

However, in any of the above methods, the lid of the mold box is pressed down at only one point, which may cause the lid to tilt forward, backward, left or right, and may prevent uniform dehydration pressing.

In addition, even if a compression plate with a relatively wide area is installed at the tip of the piston to compensate for the drawbacks of these methods, it is necessary to place the mold box on the press table and cover the mold box with cloth or cover the lid before pressing. This board will get in the way when you are doing work such as covering the tofu, and even if you use a column rotation device like the one seen in the Utility Model Publication 1983-34395, it is not suitable for tofu production, which is often done in a cottage industry with a small workshop. This is not a sufficient solution to the problem in business.

It is also possible to raise the compression plate to a height where it does not get in the way when setting the mold box, but in this case, a cylinder with a very long stroke is required, which is not very practical.

This invention provides a flip-up type compression plate devised to solve the above-mentioned problems in tofu pressing operations.

This invention will be explained below based on examples.

FIG. 1 is a perspective view of a coagulating soybean milk press equipped with a flip-up compression plate according to the present invention.

FIGS. 2 and 3 are side cutaway views showing the operating state of this Q milk press.

Reference numeral 11 denotes a base, which is assembled into a rectangular shape using square lumber or the like to an appropriate size.

Four pillars are attached to the four corners of this base, and the fixed base 13
support.

Reference numerals 14 and 14' denote a pair of left and right horizontal members for attaching the lift levers, and the beam 1 spans between the supports 120.
Supported by 5.

Reference numeral 21 denotes an elevating table, the size of which is almost the same as the fixed table 13, and a pair of left and right horizontal members 22 and 22' for attaching elevating levers are fixed to the lower surface, and the positions thereof are fixed to the base. It faces directly above the horizontal member 14°14'.

Reference numerals 31 and 32 are lifting levers, each with one end 3
1a and 32a are pivoted to the upper and lower horizontal members 14 or 22.

Also, the center points 31b and 3 of the lift levers 31 and 32
2b is rotatably stopped by a pin 33, so that the lifting levers 31 and 32 can freely rotate around the pin 33.

Further, wheels 34 and 35 are attached to the other ends 31C and 32c of the lift levers 31 and 32, and are configured to rotate in contact with the upper and lower horizontal members 14 or 22, respectively.

Although the structure of one side of the lift lever has been described above, this structure is the same for the other side, and both levers are connected by a rod 36 so that they can move in the same way.

A suitable lifting device is provided between the lifting platform 21 and the base 11,
For example, an oil cylinder or the like is interposed.

41 is a compression plate, on one side of which a pair of left and right arms 42, 42' protrude, and on the other side a hook 43
, 43' are hanging down.

The tips of the arms 42.degree. 42' are pivoted to the top of a column 44.degree. 44' fixed to the base 11, and are adapted to rotate about the top of the column as a fulcrum.

Furthermore, a spring or a sound pressure gas cylinder or the like is interposed between the arms 42 and 42' and the columns 44 and 44' to keep the compression plate 41 in a raised state at all times.

The heads of the hooks 43, 43' are connected by a rod 45 and rotatably attached to the tip of the compression plate 41 by a bracket 46'.

Further, the tip ends of the hooks 43 and 43' are hook-shaped and are adapted to be hooked onto protrusions 16 and 16' attached to the corners of the fixing base 13.

When this hook 43, 43' is pushed down 1~1° against the force of the spring interposed between the arm 42 and the column 44, and the hook-shaped portion at the lower end is locked to the protrusion 16, 16', it is compressed. The plate 41 is configured to be kept horizontal.

Next, to explain the operation of this device, first, in order to prepare for filling the mold box with coagulated soymilk, the lifting platform 21 is raised or lowered to an appropriate height as shown in FIG.
1 in a raised state.

After filling the mold box 51 placed on the lifting platform 21 with soy milk and covering the mold box with the lid 52, pull down the compression plate 41 as shown in FIG.
6' to place the compression plate in a horizontal position.

Next, the lifting device interposed between the base 11 and the lifting table 21 is operated to push up the lifting table and press the mold box lid 52 onto the compression plate 41.
The coagulated soy milk is dehydrated by pressing it from below.

As a result of the structure of the present invention as described above, the present invention has the following excellent effects.

This compression plate can be flipped up around the fulcrum, so it can be easily used when preparing for the dewatering process or when taking out products.
Since there is no need to move each item and it does not take up much space, it can provide extremely suitable equipment for the tofu manufacturing industry, which is often a cottage industry.
