Description

Tofu maker and tofu manufacturing method

The present invention relates to a tofu maker and a tofu manufacturing method for preparing tofu by pulverizing and grinding the raw beans not called.

A general known tofu manufacturing method will be described with reference to FIG. 1.

Beans, which are the raw materials of tofu, are stored in a storage tank by a bucket elevator or by hand, and then weighed by a meter, etc., as necessary, and then passed through the granulator and the washing machine one by one to remove stones and other impurities contained in the beans. At the same time it is removed and washed clean. (L1)

Thereafter, the washed beans are supplied to the soybean tank by hand or by pump, and left for a predetermined time, so that the beans contained in the soybean tank are soaked in water and blown. (L2)

Thus, when the beans are sufficiently blown in the soybeans tank, it is finely ground using a grinder to make soybean water. (L3)

At this time, soybeans should be fine particles to remove the odor during the production of tofu and can produce tofu with high elasticity while having a high taste.

When the soybean is obtained by the above process, the soybean is separated from the soybean using a filter such as a centrifuge to obtain pure soybean (hereinafter referred to as "soy milk"), which is collected separately and used for necessary purposes. (L4)

The filtered soy milk thus obtained is transported to a steamer, heated at a constant temperature (about 95 to 100 ° C.) for a predetermined time, heated, and then coagulated by adding a coagulant (salt water) in a coagulation container to obtain a soft tofu. (L5)

When the tofu is obtained by the above-described process, the tofu of the tofu is placed in a mold in a predetermined amount, compressed, and dehydrated to obtain tofu of a desired size. (L6, L7)

Second, it takes a long time to call soybeans, so rapid production is impossible.

Third, when the soybeans are not used, the soybeans are deteriorated in the season when the outside temperature is high, such as summer.

Fourth, pulverized soybeans are crushed once and then the soy milk and soybeans are separated, so it is impossible to finely grind soybeans and the amount of soybean is taken out. Soymilk is taken out using a centrifuge. Since it does not stick to the soy milk extraction is significantly reduced, thereby reducing the yield of tofu.

Fourth, because the operator in the steamed soymilk is administered by the operator by experience, the dose of the water is not constant according to the skill of the operator is not constant the tofu.

Fifth, raw material transfer between processes is made by manual labor, which is expensive.

It is to be able to mold a plurality of heads at the same time by placing in the room.

Each of these driving units is made automatically under the control of the control unit 81 installed on the front of the main body (1).

Looking at the process of manufacturing tofu using the tofu maker of the present invention configured as described above are as follows.

First, a certain amount of raw beans 2 are contained in the washing tank 5, and then the water supply pipe 11 is opened to supply water.

In this state, if each driving unit of the control unit 81 is appropriately set according to the amount of raw beans 2 and then the power is applied, the pumping motor 6 is driven, so that the washing tank 5 is rotated according to the rotation of the impeller 7. A water flow is formed in the water, and thus, the raw beans 2 in the washing tank 5 are washed by the water flow formed, and at the same time, the raw beans 2 in the housing 8 come together with water by the pumping force according to the rotation of the impeller 7. It is conveyed along the 1st conveyance pipe 9.

When the raw soybeans 2 washed as described above are pushed along with a portion of water along the first conveying tube 9, the foreign substance separating container 10 is installed on the first conveying tube, so that the raw bean introduced into the foreign substance separating container 2 Since it is light, it is transported along the first feed pipe 9 to the crushing unit 13 side with some water, but foreign matters such as stones are freely dropped and accumulated downward by their own weight because they are heavier than raw beans. , S2)

Thus accumulated foreign matter is removable from the foreign matter separation container 10 in accordance with the opening and closing means (12).

In the washing process, the raw beans 2 washed by the driving of the pumping motor 6 are transferred along the first transfer pipe 9 together with a part of the water to be contained in the first hopper 14, and then through the first hopper. Since a large number of (14a) is formed, contaminated water is removed through the through hole (14a) by washing the raw beans, and then drained to the outside through the drain pipe (16).

After the contaminated washing water is removed, the cylinder 18 serving as the first fixed-quantity supply means is driven to repeat the plunger 17 closing the outlet 14b of the first hopper 14 a predetermined number of times (about 3 times). By moving up and down, the raw beans 2 in the first hopper 14 fall freely downward. At this time, the rotary cutter 21 serving as the grinding means is being rotated by the driving of the motor 22.

The water tank 15 heated by the heater 25 with the opening of the valve 82 when the raw beans 2 in the first hopper 14 free fall along the transfer path according to the repeated lifting and lowering of the plunger 17. Since the hot water in the) is supplied on the transfer path, the raw beans 2 are more smoothly supplied to the grinding means.

When the raw beans 2 are supplied to the grinding means side together with the hot water, the raw beans 2 are finely crushed by the rotating cutter 21 and the fixed cutter 20 and then along the blowout plate 23 inclined to one side. It is contained in the hopper 26. (S3)

As the raw beans finely pulverized by the above process are contained in the second hopper 26 together with the water into which the raw beans are put, the raw soybean is the next process along the second transfer pipe 28 by the first pumping means. It is pushed to the (29) side. (S4)

That is, when the pump pump 27, which is the first pumping means, is driven to generate a pumping force, the raw soybeans contained in the second hopper 26 are pumped along the second feed pipe 28 and the grinding part 29 It is contained in the third hopper (30).

In this way, when the raw soybean water is pumped into the third hopper 30, an indirect heating means is provided at the lower portion of the third hopper so as to call the finely pulverized soybean water for about 7-8 minutes at about 60 ℃.

When the raw soybeans in the third hopper 30 are called for a predetermined time, the cylinder 34 which is the second fixed-quantity supply means is driven to repeatedly raise and lower the plunger 33 which has closed the outlet 30a of the third hopper. Therefore, the raw soybeans properly called for grinding are freely dropped along the transport path and supplied to the grinding means.

An antifoaming agent 31 is introduced to remove bubbles in the bean water on the conveying path, and the rotary cutter 39 serving as the grinding means rotates by driving the motor 40.

Accordingly, the bean water is finely ground between the rotary cutter 39 and the fixed cutter 38 and then taken out along the take-out plate 41 to be taken out of the casing 37. (S4, S5)

As the soybean finely ground by the above-described process is taken out of the casing 37 and contained in the fourth hopper 46, the soybean is followed by a third pumping means along the third transfer pipe 48 by the second pumping means. The soybean milk extraction part 51 is conveyed to the side (S7).

That is, when the pump pump 47, which is the second pumping means, is driven to generate a pumping force, the soybeans contained in the fourth hopper 46 are pumped along the third feed pipe 48 so that the soymilk extracting unit 51 It is contained in the fifth hopper (52).

When the soybeans contained in the fifth hopper 52 is introduced into the housing 54, the soybeans are compressed and transferred to the right side in the drawing by a lead screw 53 which rotates according to the driving of the motor 55. Separated into 50 and soy milk 49, the biji is taken out through the bijitake outlet 54b and placed in the biji storage bin 56, soymilk 49 is taken out through the soymilk outlet 54a and in the soymilk reservoir 57 (S8)

At this time, the pitch of the lead screw 53 is narrower toward the tip (the direction of the busy direction), so that the compressive force is increased and the load applied to the motor 55 is minimized.

The busy paper obtained by the above process is stored and used for a separate use such as feed.

When the soymilk 49 obtained by the soymilk extraction process is filled in the soymilk reservoir 57, the regulator valve 60 installed on the first soymilk transfer pipe 58 is opened to steam the soymilk in the soymilk reservoir 57 within a short time. It supplies in the steaming tank 61 of the part 59.

The reason why the regulator valve 60 is installed on the first soymilk transfer pipe 58 to supply the soymilk simultaneously in the steam bath 61 in a short time is due to the heating of the heater 62 installed in the steam bath 61. Due to the high temperature inside the steaming tank, when the soymilk 49 extracted from the soymilk extracting unit 51 is directly supplied into the steaming tank 61 along the first soymilk transfer pipe 58, a certain amount of soymilk is filled in the steaming tank. This is to prevent the end of the soymilk initially pressed before losing because it is stuck.

As described above, after a certain amount of soymilk 49 is quickly filled in each steam tank 61 by opening the regulator valve 60, the regulator valve 60 closes the first soymilk transfer pipe 58. .

Thereafter, while the heater 62 continuously heats the steam bath 61, the cylinder 64, which is the kneading means, is driven to repeatedly raise and lower the kneading plate 63 while steaming the soymilk to a predetermined temperature. (S9 )

As a result, the soymilk does not stick to the steam bath 61.

After steaming the soymilk for the set time in the steaming unit 59, the regulator valve 66 installed on the second soymilk transfer pipe 65 is opened to transfer the steamed soymilk to the set temperature.

In the above soymilk transfer process, the regulator valve 70 of the water supply unit 68 installed on the second soymilk transfer pipe 65 is opened to store a predetermined amount of soymilk in the soymilk transferred along the second soymilk transfer pipe 65. 67) is added to solidify to obtain a soft tofu (S11)

At this time, since the liver water 67 in the water supply tank 69 is evenly mixed with the soymilk being transferred, it is possible to uniformly inject the water always without a separate kneading operation so that the taste of the tofu can be kept constant. .

On the other hand, if you want to draw directly from steamed soy milk without drinking tofu and drink it as soy milk, it is possible to obtain a warm soy milk by opening the valve 72 installed on the discharge pipe 71. (S10)

As described above, the soymilk 49 steamed in the steaming unit 59 is transferred to the second soymilk conveying tube 65 while being solidified by the introduction of the jailer 67, that is, the soft tofu is formed into the molding unit 73. When it is contained in the tofu supply hopper 78 installed on the side, the predetermined amount of the tofu head 83 is taken out to the forming mold 74 positioned on the tofu supply position by opening the valve 80 installed on the tofu supply pipe 79. Done.

One side of the soft tofu supply position is provided with a sensing means 77 such as a sensor for detecting a forming mold 74 and opening a valve 80 installed on the soft tofu supply pipe 79 for a predetermined time to extract a predetermined amount of the soft tofu. Therefore, it is possible to always hold a certain amount of the tofu in the forming mold (74).

After the predetermined amount of the tofu is contained in the forming mold 74 in the tofu supply position by the operation as described above, the forming mold 74 containing the tofu 83 is transferred to directly under the pressing plate 75, and then the control unit 81 By operating the cylinder 76, the pressing plate 75 is simultaneously lowered to squeeze the soft head in the forming mold 74, so that the moisture contained in the soft head is dewatered in the pressing plate 75. It is compressed while exiting through (75a) it is possible to obtain a complete tofu. (S12, S13)

As described above, the process of producing the tofu while feeding raw beans 2 to the washing tank 5 and automatically transferring the raw materials for each process is performed. As long as the raw beans 2 are continuously added to the washing tank 5, Automatic production of tofu is possible.

As described above, the present invention can obtain various effects as follows.

First, the first grinding in the state of raw beans and then finely crushed to obtain soybean water to minimize the phenomenon of falling sugar contained in the beans, the resulting tofu taste is much lighter than conventional tofu.

Second, since the soaking operation in the state of the first crushed raw beans to minimize the time required to call the beans it is possible to produce tofu quickly.

Third, since tofu is produced by injecting raw soybeans without soaking soybeans, the deterioration of soybeans due to inventory is prevented in advance.

Fourth, the soy milk and sesame are separated in the state of crushing the raw soybeans once and then soaked in the second fine grinding state to minimize the extraction amount of soybeans by the fine grinding of soybeans, and the soymilk is extracted by compressing the soy milk. It is possible to maximize the production of tofu, thereby greatly improving.

Actually, the bean of the kiln was produced tofu by the method using the tofu maker of the present invention and the conventional method, respectively, in the present invention produced about 300 tofu, the conventional method produces only about 150 tofu It wasn't.

Fourth, when the steamed soy milk is transferred along the second soymilk transfer pipe automatically inputs a certain amount of water, so that the amount of water kept in the water can be kept constant at all times.

Fifth, raw materials are automatically transferred between processes, thereby reducing expensive personnel costs.

Sixth, the equipment for producing tofu is provided in the main body to minimize the space required for the installation of the equipment, as well as to produce hygiene in the narrow space.

Seventh, the heating of the raw material is safe because it consists of a heater operated by electricity.
