Description

Home instant tofu manufacturing device and the method of manufacturing the tofu using the same as}

The present invention relates to a household heating-type tofu manufacturing apparatus and a method for manufacturing tofu produced thereby, and more particularly, to manufacturing at least one tofu-related food such as soft tofu or soft tofu using a household cooking apparatus equipped with a cutter and an electric heater. It relates to a household heating-type tofu manufacturing device capable of and a method for manufacturing tofu produced thereby.

In general, tofu products are one of the most popular processed foods made from soybeans and are representative foods rich in high-quality vegetable protein.

The manufacturing method of such tofu is described as follows. Wash the beans well and soak them in water for 7-8 hours in the summer and 12 hours in the winter, then add water little by little and grind them in a grinder. This is called kongbiji, and it is boiled directly in a pot or heated by blowing steam from a boiler. Due to this heating, the fishy smell of beans is removed and at the same time, a large amount of protein is dissolved in bean curd. After heating, put it in a hemp bag, filter it, and divide it into soybean water [豆乳] and bean curd.

At this time, if the bean curd is too cold, it is difficult to squeeze it, so filter it while it is hot and squeeze the bean water as much as possible. When the soybean water cools down to a certain extent and reaches 70~80℃, add the coagulant. In the past, brine (liquid, salty and bitter liver soup dissolved in table salt, the main component of which is magnesium chloride) was used as a coagulant, but in recent years, a powder coagulant containing calcium sulfate as the main component is used.

If you add a coagulant, the protein in the soybean water hardens, so leave it as it is for a while, then scoop out the clear top water and discard the coagulum that has settled at the bottom on a box with small holes on all sides, spread cotton and pour it, close the lid, and press it with a pressing stone to drain the water through the small hole. . When the tofu is sufficiently hardened, put the whole box into the water, remove the box from the water, and soak the tofu in the water for a while. This will release all the extra coagulant and improve the taste. If it is properly cut, it becomes a finished product. This finished tofu contains 84 kcal, 82.8% moisture, 9.3 g protein, 5.6 g lipid, 0.9 g ash, 1.4 g sugar, 0.2 g fiber, 126 mg calcium, 140 mg phosphorus, and 84 kcal per 100 g edible part. It consists of iron 1.5mg, sodium 5mg, potassium 90mg, vitamin B1 0.03mg, vitamin B2 0.02mg, niacin 0.2mg.

However, because such conventional tofu is mainly mass-produced in tofu manufacturing factories or shops and sold to consumers due to complex manufacturing processes and facilities, there is a limit to individually making tofu or tofu-related foods in each household.

On the other hand, in mass media such as TV and newspapers, it is often reported that the results of hygiene inspections by tofu manufacturers show that several times more E. It is a trend that the anxiety of consumers in each household is increasing day by day.

In order to meet the needs of these consumers, tofu manufacturing devices that can conveniently make and eat tofu-related products directly at home have been steadily developed and marketed. For example, Korean Utility Model Registration No. 20-0250843 (2001 October 05, 2018), the drive motor rotating shaft is separated in two to prevent overloading the drive motor, and the blade part is fixedly coupled to the main body so that the user can easily clean the sieve and prevent safety accidents at the same time. Disclosed is a household heated tofu manufacturing apparatus with a blade unit fixed coupling type that eliminates the inconvenience of having to re-install the blade unit.

In addition, in Korean Registered Patent Publication No. 10-1211580 (December 6, 2012), one driving motor simultaneously crushes and crushes raw and wet soybeans, while a centrifuge causes okara and soybean water ( Soybean milk) is formed to provide rapid workability and improved productivity according to tofu manufacturing by providing a tofu manufacturing device that separates soybean milk), and in particular, raw soybean or An apparatus for manufacturing tofu using wet soybeans is disclosed.

In addition, Korean Patent Registration No. 10-1461618 (November 07, 2014) discloses that fresh tofu is automatically produced when consumers put beans and water in a home or restaurant, so that the taste of tofu produced in large quantities is more suitable for the appetite. Since tofu can be produced directly, it is convenient for the user, and a home tofu maker is disclosed in which dry soybeans that are not soaked in water can be directly used to grind the soybeans very finely and eat fresh tofu immediately.

In addition, Korean Patent Registration No. 10-2208213 (January 21, 2021) discloses that tofu, soybean milk, and okara can be produced from soybeans more simply and conveniently during the production of tofu, soybean milk, and okara, and the conventional tofu manufacturing method In comparison, a home tofu maker capable of shortening the manufacturing process and time is disclosed.

However, such conventional technologies take a relatively long heating time to heat and grind beans in two stages when heating beans, or the drive unit and control unit are placed on top of the entire device to solve waterproofing. Or, the overall structure is complicated, so cooking is not convenient, and it has a structure that is easy to cause minor malfunctions.

In addition, when tofu is made with conventional tofu manufacturing devices, not only the total amount of tofu and its size are small, but especially when the sheath heater is used, the heating area of the bean water is small when heating the bean water to at least 80 ° C. Only the temperature of the lower part of the container adjacent to the rapidly rises and burns the protein contained in the soybean water, making it inedible and bitter.

The present invention was made to solve the problems of the prior art described above, and an object of the present invention is to control the amount of okara to be discarded than before by controlling the motor RPM when grinding soybeans in a household cooking appliance equipped with a cutter and an electric heater. It is to provide a home heating type tofu manufacturing apparatus and a method of manufacturing tofu produced thereby, which can reduce and increase the total amount of tofu produced accordingly.

Another object of the present invention is to reduce the amount of okara to be discarded compared to the prior art by adjusting the type, order and content of the coagulant in the process of heating and grinding soybeans in a household cooking appliance equipped with a cutter and an electric heater, thereby reducing the amount of okara It is to provide a home heating type tofu manufacturing device capable of increasing the amount of tofu and a method of manufacturing tofu produced thereby.

Here, it is preferable that the control circuit unit 340 automatically controls the operation of the heater 170 and the power generator 240 based on preset order and time information when the user presses desired cooking and start buttons.

Hereinafter, with reference to the accompanying drawings, a process for manufacturing soft tofu with moderately drained water and all tofu (square tofu) that has been squeezed after removing some of the water produced by a home heating type tofu manufacturing apparatus according to a preferred embodiment of the present invention will be described.

1. Bean preparation step (S10)

Wash the dried beans to make tofu prepared in advance and scoop them out. At this time, dried beans can be used immediately or after being soaked in water for a certain period of time before use. Usually, it is preferable to use after soaking in water for 7 to 8 hours in summer and 12 hours in winter.

The user puts dried or soaked beans of a previously prepared capacity into the cooking container 110 of the home tofu manufacturing apparatus according to the present invention along with water, and closes the upper part of the cooking container 110 with the cover part 140.

In a preferred embodiment of the present invention, dry beans: water is mixed at a volume ratio of 1:10, wet beans: water is preferably mixed at a volume ratio of 2:5, and the volume expands due to heating and grinding of beans. Considering that, it is preferable that the total volume of the beans and water does not exceed 75 to 80% of the total volume of the cooking container 110 so that the heated bean water does not overflow the cooking container 110.

2. Bean heating step (S20)

The control circuit unit 340 of the control unit 300 is such that the cover unit 140 is normally coupled to the top of the cooking container 110, the connection plug 150 of the container unit 100 and the plug socket of the body unit 200 ( 230) is normally coupled, and the cooking command or cooking control command applied by the user only when it is determined that the upper coupling 180 of the container unit 100 and the lower coupling 250 of the body unit 200 are normally coupled Power for performing is supplied to the power generator 260 or the heater 170, and is installed inside the handle part 130 through the connection plug 150 and the plug socket 230 or the bowl base ( 120) may be supplied to the foam sensor 320 or/and the temperature sensor 330 installed on the underside of the heating support plate 122 provided on the lower side.

At this time, when the user sequentially presses the soft tofu button and the start button provided on the operation panel 310 of the controller 300, the control circuit unit 340 of the controller 300 sets the heater 170 to the internal temperature of the cooking vessel 110. Heats up to 95~98℃ first, and when the internal temperature reaches 95~98℃, stop heating, wait for 1~3 seconds, and heat again for 1~5 minutes within the range of not exceeding 100℃ 100 Heating within the range not exceeding ℃ (for example, 1 to 3 seconds) and heating is stopped (for example, 2 to 5 seconds). At this time, the control circuit unit 340 of the control unit 300 periodically detects the internal temperature of the cooking container 110 from the temperature sensor 330, and if the detected value is less than 90 ° C, the heater 170 continues to heat and the temperature is 100 ° C. If it is abnormal, the control operation of stopping the heating of the heater 170 is repeatedly executed.

Here, the control circuit unit 340 of the control unit 300 primarily heats the heater 170 until the internal temperature of the cooking container 110 reaches 95 to 98 ° C., and when the internal temperature reaches 95 to 98 ° C. The reason for the secondary heating by the intermittent heating method for 1 to 5 minutes so as not to exceed 100 ° C. is due to the limitation of the capacity of the cooking container 110 for cooking using electric energy. When heated to 100 ° C., not only can the cooking contents overflow in an uncooked state, but also the soybean paste containing water flows into the main body part 200, which can cause equipment failure or electric shock. .

However, when the user sequentially presses the All button and the Start button provided on the operation panel 310 of the control unit 300, the control circuit unit 340 of the control unit 300 determines that the internal temperature of the cooking vessel 110 reaches 90°C. Heat the heater 170 to reach At this time, the control circuit unit 340 of the control unit 300 periodically detects the internal temperature of the cooking vessel 110 from the temperature sensor 330, and if the detected value is less than 90 ° C, the heater 170 continues to heat, and the temperature exceeds 100 ° C. A control operation to stop heating of the back surface heater 170 is repeatedly executed.

Meanwhile, the control circuit unit 340 of the controller 300 operates the heater 170 when the detected value of the internal temperature of the cooking vessel 110 reaches a preset temperature (eg, 91°C or 98°C). It can be rotated for 1 to 2 seconds to maintain a uniform internal temperature of the cooking container 110 without beans sticking to the bottom of the cooking container 110 corresponding to the upper part. In the embodiment of the present invention, the container unit The blade 160 connected to the upper coupling 180 of 100 is rotated at a low level of 1 step (12,400 RPM) for 1 to 2 seconds to stir the beans inside the cooking container 110 at a low level. there is.

3. Bean crushing step (S30)

Subsequently, after the second or third heating operation in the soft tofu manufacturing process, the control circuit unit 340 of the control unit 300 heats the cooking vessel 110 for 15 to 20 minutes while maintaining the internal temperature in the range of 90 to 100 ° C. Then, by driving the power generator 240, the blade 160 fixed to the upper part of the upper coupling 180 of the container part 100 connected to the lower coupling 250 of the main body part 200 is shown in Table 1 above. It rotates in an intermittent rotation method that stops after driving for a certain period of time within the range of 6 to 8 stages of motor rotation speed (23,000 to 26,300 RPM).

In a preferred embodiment of the present invention, the intermittent rotation method performs a process of grinding beans by repeatedly executing the operation of driving the power generator 240 for 15 seconds and stopping for 5 seconds 8 to 10 times.

On the other hand, after the heating operation in the all part manufacturing process, the control circuit unit 340 of the control unit 300 heats the cooking container 110 for 15 to 20 minutes while maintaining the internal temperature of the cooking vessel 110 in the range of 90 to 100 ° C. 240) to drive the blade 160 fixed to the upper part of the upper coupling 180 of the container part 100 connected to the lower coupling 250 of the body part 200 at the motor rotational speed 4 of Table 1 above. It rotates in an intermittent rotation method that stops after driving for a certain period of time within the range of ~6 steps (20,000~23,000 RPM).

In a preferred embodiment of the present invention, the intermittent rotation method is that the grinding time and cycle of the power generator 240 is 13 to 17 seconds drive, 3 to 7 seconds stop operation repeatedly performed for 4 to 8 times to grind beans. run

Here, the reason for using the intermittent rotation method is that when grinding beans with water, if the blade 160 continues grinding at a constant speed for a certain period of time, there is no significant change in the internal arrangement of beans, so the particles of the ground beans are uniform. Not only does it not work, but the grinding efficiency is reduced. Since this is a factor that can directly affect the quality of tofu, in order to solve this problem, when the power generator 240 is driven for a certain period of time and then stopped, the ground beans sink to the bottom of the cooking vessel 110, and at this time When the power generator 240 is driven again, soybean pulverized particles are pulverized in a new arrangement, so that the pulverized soybean particles can be pulverized more uniformly, thereby improving not only the grinding efficiency but also the quality of tofu. .

At this time, by adjusting the grinding time and the number of repetitions of the cycle, the degree of fineness of the particles of the ground beans can be adjusted.

4. Separation step of soybean water and okara (S40)

Next, the user uses a previously prepared 30-60 mesh strainer or filter to filter out particles of 30 to 60 mesh or less with okara, and the particles of 30 to 60 mesh or more that pass through the strainer or strainer are turned into soybean containing protein. separate

5. Coagulant mixing step (S50)

Next, in order to coagulate the protein contained in soybean water, 3 to 10 g of coagulant powder selected from among magnesium chloride, calcium sulfate, and GDL (Glucono-Delta-Lactone: Gluconodelta Lactone) is put into the prepared tofu container, and the prepared 85 ° C. After putting the above soybean water into the tofu container, stir it for 3 to 5 seconds to mix it evenly, and then leave it at room temperature without moving or shaking for a preset time (eg, 3 to 10 minutes) for complete solidification. .

The reason why GDL is used here is that it dissolves uniformly in soymilk above 80℃ and reacts slowly, so it has rich water retention and uniform coagulum, so it is suitable for cooking packaged tofu or bulk soft tofu. In addition, G.D.L can be solidified more densely and strongly by increasing the coagulation time even at 60℃. This advantage has relative convenience compared to the difficulty of handling magnesium chloride, a fast-acting coagulant, at 80° C. or higher.

At this time, when the coagulant powder is added after putting soybean water in the tofu container, the coagulant is not uniformly mixed, so the coagulant force is reduced.

In the present invention, it is preferable to use two coagulation methods in order to solve these problems. First, put coagulant powder mixed with a little water or soybean water into the inside of the tofu container, and then put the prepared soybean water into the tofu container. can be better

In addition, secondly, if soybean water is first put inside the tofu container and coagulant dilution mixed with coagulant powder and a little water or soybean water is put in a separate container, the coagulant and soybean water are mixed and diluted evenly, so that coagulation can be better. .

At this time, the reason why the temperature of the soybean water should be maintained above 85 ℃ is because it was found that the temperature of the soybean water solidifies uniformly at 85 ℃ or higher, but does not solidify well below 85 ℃.

6. Soft tofu or tofu manufacturing step (S60)

After that, the user can complete the silken tofu or all of the tofu.

When the user makes soft tofu, mix the coagulant and soybean water, and after 3 to 5 minutes, when the soybean water is coagulated, scoop it out with the top water to complete soft tofu.

On the other hand, when the user makes modubu, after 3 to 5 minutes of mixing the coagulant and soybean water, scoop out the clear supernatant from the upper part of the tofu container and discard the protein coagulum that has settled at the bottom. After spreading and pouring, close the lid and press down with a pressing stone to complete the whole part as the water escapes through the small hole in the tofu molding container.

At this time, when the tofu is sufficiently hardened, put the whole tofu molding container into the water, remove the box from the water, and soak the tofu in the water for a while. This will remove all the extra coagulant and make the tofu taste better.

Hereinafter, examples of production of both tofu (square tofu) and silken tofu according to a preferred embodiment of the present invention will be described in turn.
