Description

[Detailed description of the invention] (a) Technical field of the invention The present invention relates to a method and apparatus for removing oil from raw fried tofu.

(1)) Background of the technology Recently, with the remarkable development of the restaurant industry, seasoned fried tofu has been produced and sold in large quantities. This flavored fried tofu is
Raw fried tofu is produced in large quantities by major manufacturers and then purchased by flavor processors, each of whom season it using their own unique methods.

However, raw fried tofu contains a large amount of excess and free oil, so even if you put this raw fried tofu in a pot and simmer it with the stock, the flavor will not mix well, resulting in an uneven taste and no commercial value. It is.

Therefore, before seasoning, it was necessary to drain the oil from the fried tofu.

(c) Conventional technology and problems Traditionally, the method of removing oil from fresh fried tofu was done manually by pouring water into a pot, heating it, adding fresh fried tofu, then placing heavy weights on top and simmering to remove the oil. was doing.

However, this method not only causes problems such as the oil being removed too much due to the variation in the simmering time after placing the heavy ingredients, such as dryness or damage to the fried tofu.
The reality is that the work relies on manual labor, so there are problems such as rising labor costs and high product prices (I), and workers getting burned during the work.

In addition, since the worker has to take out the drained raw fried tofu or put the raw fried tofu in the pot each time, the work is complicated and productivity is low.

(d) Purpose of the Invention The present invention provides a method and apparatus for automatically draining oil from raw fried tofu, and also makes it possible to maintain a constant level of oil removal from raw fried tofu. The purpose is to provide and solve the following problems.

(e) Structure of the invention, that is, the first key point of the present invention is related to a method for removing excess oil from raw fried tofu. L
At least one piece of fried tofu is placed, this is automatically transferred by a conveyor, the raw fried tofu is immersed in water, and pressing force is applied to the raw fried tofu at least once to remove excess from -1- muddy fried tofu. It is characterized by squeezing out oil.

The second gist of the present invention relates to a device that is suitably adopted for removing excess oil from raw fried tofu. A container is attached to the blade on the moving path of the conveyor.
The present invention is characterized in that at least one cylinder is provided at a location corresponding to the intermediate immersion portion of the conveyor, and the cylinder is provided with a cylinder that can freely move forward and backward.

(f) Examples of the Invention The present invention will now be described in detail with reference to Examples. (1) shows a conveyor mounted on a pedestal (2), and the conveyor (1) has one-digit gears (3) rotatably mounted on both left and right ends of the pedestal (2). 4)...
・The conveyor (1) is roughly composed of a chain (5) that is passed between the gears (3), (4), and the conveyor (1) is immersed in a water tank (6). When the motor (7) is driven, the chain (5) is intermittently moved in the direction of the arrow in FIG.

-3= Oil permeable containers (8) are attached to the chain (5) in a direction perpendicular to the direction of movement of the chain (5) with gaps () between them. In this case, the container (8) is
It is formed by a rectangular bottom plate (9) and front, rear, left and right side plates (10), (11), (12) and (13) hanging from the four peripheral edges of the bottom plate (9), and this bottom plate (9) and side plates (10). (11)
(12)'' (13) are each provided with a hole (14).

Further, (15) is a lid attached to the upper end of the container (8), and side plates (10) and (11) to which the lid (15) is attached.
1. A long hole (16) is provided in the downward direction, and the long hole (16)
1) which can be moved up and down and freely opened and closed via the boss (17)
(=1 is digitized.

In this case, the container (8) has a bottom plate (9) instead of the above.
) may be made oil permeable, or the side plates (10) (11
)(12) Only (13) may be made oil-permeable.In short, it is sufficient to configure the structure so that the oil squeezed from the raw fried tofu (18) flows out of the container (8). Needless to say, the container (8) may be made of mesh. A chute (not shown) is installed at the left end of the conveyor (1) to sequentially feed the raw fried tofu (1 day) to the containers (8). In this case, one piece of raw fried tofu (18) may be supplied to the container (8), or alternatively, two or more pieces may be supplied.

The transfer path-1 of the conveyor (1) is provided with a cylinder (19) such as a hydraulic cylinder or an air cylinder at a location corresponding to the intermediate immersion portion (1) of the conveyor (1); The piston rod (20) can be removed from the cylinder (19) with the piston rod (20) facing downward, and the piston rod (20) is provided with a suppression plate (21) at its tip.
When the raw fried tofu (18) is transferred to just below the shilling (19), the electric and magnetic piston rod (20) advances (protrudes).
) to squeeze out the oil.

In the above embodiment, only the case where one cylinder (19) is provided is described, but the present invention is not limited to this, and it goes without saying that two or more cylinders (19) may be provided. . Also, in the case of an air cylinder, you can adjust the air pressure to optimize the pressurization condition. Instead, adjust the travel distance of the biston rod/F (20) to optimize the pressurization condition. It's okay.

Next, to explain its operation with reference to the diagram, when the conveyor (1) is driven, the raw fried tofu (18) is sent sequentially from the chute to the containers (8) and stored therein, and in this case, 5 layers are stacked in 6 stages. They are intermittently moved in the direction of arrow (A) in a row.

Then, the raw fried tofu (1) was transferred by the conveyor (1).
8) ... is gradually sinking into the water tank (6) b, and at this time,
The raw fried tofu (18) in the container (8) floats and melts due to the buoyancy of water, but it comes into contact with the lid (15) and is prevented from floating. When the container (8) containing the raw fried tofu (18) is transferred to the lower part of the cylinder (19), the piston rod (20) protrudes and is pressed from above the lid (15). Then, the lid (15
) is gradually lowered along the elongated hole (16) of the container (8), and the lid (15) pressurizes the raw fried tofu (18) to squeeze out excess oil from the raw fried tofu (18). , this oil flows from the hole (14) in the container (8) to the container (8).
It flows outside.

In this way, move the lid (15) up and down to fry the raw tofu (18
), it is possible to remove the cylinder (19) without having to set the position strictly.
It's extremely convenient as you only need to do it.

In the example described above, the cylinder (19) is fixed and the container (8) is transferred below the cylinder (19).
In this case, the conveyor (1)
Rather than moving intermittently, the cylinder (19) is moved in accordance with the movement of the conveyor (1), and as the cylinder (19) is moved, the screws (20) are gradually moved. Needless to say, it is also possible to press the fried tofu (18) by protruding it to squeeze out the oil. In this case, since the degree of squeezing of the fried tofu (18) is adjusted by air pressure or the protrusion of the screw 1-rond (20), accidents such as squeezing too much oil or squeezing insufficient oil do not occur. .

(g) Effects of the Invention As explained in 2, when squeezing oil from raw fried tofu, the present invention simply adjusts the amount of protrusion of the piston rod according to the air pressure of the cylinder or the number of fried tofu. Therefore, the adjustment can be made extremely easily, and once adjusted, the fresh fried tofu can always be squeezed appropriately and uniformly.

In addition, since the present invention extracts oil automatically and continuously, the number of workers can be reduced, and as a result, labor costs can be significantly reduced, and oil application work can be done at low cost. be.

Furthermore, since the oil application work is not done manually, there are no accidents such as burns to workers.
