The present invention relates to a tofu manufacturing apparatus, and more particularly, to a tofu manufacturing apparatus capable of obtaining a complete tofu in a short time by the batch processing of the raw material input, washing and manufacturing process for the production of tofu.

Tofu is a food produced using soybean as a main raw material, and it is recognized as a healthy food and is frequently used.

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

Soybean, which is the raw material of tofu, is stored in a storage tank and weighed by a meter, etc. as needed, and then passed through the stone and washing machine by a certain amount in order to remove stones and other impurities contained in the bean and to clean it at the same time. (L1 )

After that, the washed beans are supplied into the soybeans tank by hand or by pump, and soaked in water for about 8 hours in summer and about 14 hours in winter, so that the beans contained in the soybeans tank are soaked in water. (L2)

As such, when soybeans have sufficient soaking in the soybean soaking tank, they are finely ground using a grinder to make soybean water. (L3)

At this time, soybeans should be fine particles to eliminate the odor during the production of tofu and can produce a good tofu while the taste is high.

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 soymilk), and the soybean is collected separately and used for necessary purposes. (L4)

The filtered soymilk thus obtained is transported to a steamer, heated at a constant temperature (approximately 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 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)

When preparing tofu by performing the above-described process, there were the following problems.

During soaking of soybeans for 8 to 14 hours in water to cause soaking, proteins, fats, sugars and other organic matters contained in soybeans were dissolved in water and lost.

In addition, when the nutritional component contained in the beans is lost, the taste of tofu produced using the beans is lowered and the yield of tofu per weight unit is lowered.

In addition, the apparatus for preparing tofu by putting dry beans has a problem that the consumer has a hygienic suspicion about the completed tofu because the washing process is insufficient.

In addition, the use of a boiling pot for the production of tofu, but there was a problem that the soymilk is deformed or the taste is changed by the heat applied.

Since the structure of the crusher and the crusher is similar to that of the general crusher and the crusher used in the tofu manufacturing apparatus, detailed description is omitted.

According to FIG. 5, the crusher includes a first crusher 320 and a second crusher 330. However, the number of crushers may be two or more in order to finely crush soybean particles.

The crusher 310, the first crusher 320, and the second crusher 330 are configured to be operated by the driving force of the motor 340 by using a mechanism such as a pulley and a timing belt.

Soybeans are passed through the crusher 310, the first crusher 320 and the second crusher 330 in order to mix the fiber (bean) and soy milk, so that only the soymilk is extracted using the centrifuge (400). After that, the soymilk storage tank 500 is stored. In addition, the sewage separated from soy milk is stored separately and used for other purposes.

When the beans are crushed, bubbles are generated in the soy milk, and if the left bubbles are left, it becomes difficult to prepare the tofu. As shown in FIG. 8, the antifoaming agent stored in the antifoam storage tank 510 is the antifoam pump 520. ) So that it can be added to soy milk at regular intervals. When the amount of antifoaming agent is increased, the excessive antifoaming agent is recycled to the antifoaming storage tank 510.

Crusher is a device that crushes soybeans. Crusher is a device that finely crushes finely crushed soybeans.It is divided into several stages according to the size of soybean particles, rather than grinding the first soybean into fine particles using a single device. It is desirable to have the work done.

Therefore, in the present invention, the grinding machine is composed of the first and second grinding machines (320, 330), the number of configurations of the grinding machine can be increased if necessary.

Soybeans that have been crushed are divided into soy milk and fiber-based soybeans in which water-soluble proteins and fats are dissolved in water.However, separating soy milk and soy milk for the production of tofu is recommended. desirable.

Separating the busy and soy milk is to use a centrifuge (400). The centrifuge uses a general type, so detailed description is omitted.

When the beans are crushed, bubbles are generated in the soy milk, and if the generated bubbles are left, it is difficult to prepare the tofu, so that the antifoaming agent is added to the soymilk at a predetermined time interval to remove the bubbles by operating the antifoam pump 520. At this time, the information on the defoamer injection interval and the dosage is stored in the control panel 700.

When the soy milk and the sewage is separated by the centrifuge 400, the separated soy milk is stored in the soy milk storage tank 500, the sewage is discharged to the outside to be stored separately for use.

When soymilk is stored in the soymilk storage tank 500, the water level sensor 710 installed in the soymilk storage tank 500 outputs a signal about the level of soymilk to the control panel 700.

If it is determined by the control panel 700 receiving the output signal that the amount of soymilk stored in the soymilk storage tank 500 is more than a predetermined number is composed of the first, second and third heaters (610, 620, 630) The soymilk is moved to the heater 600 so that the soymilk is heated. Each heater mixes externally supplied steam with soymilk so that the soymilk is heated by the mixed steam.

In this case, the first, second and third heaters 610, 620, and 630 heat the soymilk at a temperature of 40 ° C., 70 ° C., and 97 ° C. That is, the soymilk initially introduced into the first heater 610 is heated to 40 ° C. in the first heater 610 but discharged at room temperature, but is introduced into the second heater 620.

The second heater 620 discharges the soymilk at 40 ° C. to 70 ° C., and then discharges the soymilk at 70 ° C. to the third heater 630 to be heated to a temperature of 97 ° C.

The soymilk heated by the heater is introduced with a brine used as a coagulant for the production of tofu.

Soymilk coagulates when soymilk is mixed with soymilk when mixed with soymilk, such as gluconodeltalactone, calcium sulfate, magnesium, refined salt, and the like. Stir the soymilk using.

Soy milk mixed with the brine is started to solidify, so before the complete solidification is added to the pressing container 800 formed in the shape of the head. After applying the pressing cloth to the upper surface of the soymilk introduced by using a weight or the like on the upper portion of the pressing cloth, the water contained in the soymilk is separated through the pressing cloth to obtain a complete tofu.

When tofu is produced and soymilk is consumed, the buoy 710b moves downward and the buoy 710b of the water level sensor 710 contacts the bottom contact, and a signal is output to the control panel 700.

The control panel 700 receiving the signal of the lower contact 715b determines that the soymilk of the soymilk storage tank 500 has been consumed, and informs the user of the soymilk storage, and the user newly stores the soymilk in the soymilk tank 500. Prepare fresh tofu.

The present invention configured as described above, so that the tofu product can be obtained in a short time by washing, impurity removal and heating of the soybean raw material tofu supplied to the outside for the production of tofu is made in a batch. It has an effect.
