Description

BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to an apparatus for manufacturing ground soybean for tofu and a method for manufacturing ground soybean produced thereby, and more particularly, to at least one tofu such as soft tofu or whole tofu by using a household cooking appliance equipped with a cutter and an electric heater. It relates to a soybean pulverized product manufacturing apparatus for tofu capable of manufacturing related foods, and to a method for manufacturing soybean pulverized product manufactured thereby.

In general, tofu products are the most popular processed products among foods made from soybeans and can be said to be representative foods rich in high-quality plant protein.

The manufacturing method of such tofu will be described as follows. Wash the beans well, soak them in water for 7-8 hours in summer and 12 hours in winter, then add water little by little while adding them to a grinder and grind finely. This is called bean curd, and it is either boiled directly in a pot or heated by blowing steam from a boiler. Due to this heating, the fishy smell of soybeans is removed and protein is dissolved in a large amount of okara. After heating, put it in a cloth, squeeze it, and divide it into bean water [豆乳] and okara.

At this time, it is difficult to squeeze the okara if it is too cold, so filter it while it is hot and squeeze the soybean water as much as possible. When the soybean water has cooled down to about 70~80℃, add a coagulant. In the past, bittern water (a liquid salty and bitter soup dissolved in salt, the main ingredient was magnesium chloride) was used as a coagulant, but in recent years, a powder coagulant containing calcium sulfate as the main ingredient is used.

If you add coagulant, the protein in the soybean water hardens, so leave it for a while, then scoop out the clear water and throw away the coagulated material that has settled at the bottom. Pour the coagulated material into a box with small holes in all directions. . When the tofu is hardened enough, put the box in the water, remove the box from the water, and soak the tofu in water for a while. This will drain all the extra coagulant and improve the taste. If you cut it properly, it becomes a finished product. This finished tofu is 84 ㎉ per 100 g of edible part, 82.8% moisture, 9.3 g protein, 5.6 g lipid, 0.9 g ash, 1.4 g carbohydrate, 0.2 g fiber, 126 mg calcium, 140 mg phosphorus, It consists of iron 1.5mg, sodium 5mg, potassium 90mg, vitamin B1 0.03mg, vitamin B2 0.02mg, niacin 0.2mg.

However, due to the complicated manufacturing process and facilities, the conventional tofu is mainly produced in large quantities in tofu manufacturing factories or shops and sold to consumers, so there is a limit to individually making tofu or tofu-related foods at each home.

On the other hand, mass media such as TV and newspapers often report that the sanitary inspection results of tofu manufacturers have detected E. coli several times higher than the standard value in tofu products due to poor storage of ingredients, use of poor materials, and poor cleanliness of manufacturing facilities. Therefore, the anxiety of consumers in each household is increasing day by day.

To meet the needs of these consumers, a tofu manufacturing device that can conveniently make and eat tofu-related products directly at home has been continuously developed and marketed.

Disclosed is a home-made tofu maker in which tofu can be manufactured directly, which is convenient for users, and which can be eaten directly by directly using dried soybeans that have not been soaked in water and grinding soybeans very finely.

In addition, Republic of Korea Patent Publication No. 10-2208213 (January 21, 2021) discloses that tofu, soymilk, and okara can be manufactured more simply and conveniently from soybeans when manufacturing tofu, soymilk, and okara, and A home-made tofu maker that can shorten the manufacturing process and time compared to that is disclosed.

However, such conventional techniques take a relatively long overall heating time to proceed with heating and pulverization through secondary heating when heating beans, or a driving unit and a control unit are disposed 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 prone to minor breakdowns.

In addition, when making tofu using conventional tofu manufacturing devices, not only the overall amount and size of tofu are small, but especially when a sheath heater is used, the heating area of the bean water is small when heating the bean water to at least 80℃ or more, so the heater Only the temperature of the bottom part of the container adjacent to the container rapidly rises, which burns the protein contained in the soybean water and produces a bitter and bitter taste, making it impossible to eat.

Next, the user uses a pre-prepared 30-50 mesh sieve to filter out particles of 30-50 mesh or less with okara, and particles of 30-50 mesh or more that pass through the sieve are separated into soybean water containing protein.

5. Coagulant mixing step (S50)

Then, in order to coagulate the protein contained in the soybean water, 3 to 10 g of magnesium chloride or 5 to 10 g of coagulant powder such as GDL (Glucono-Delta-Lactone) is put into the prepared tofu container, and then prepared 85 After putting soybean water above ℃ into the inside of the tofu container, stir for 3 to 5 seconds to mix evenly, and then leave at room temperature without moving or shaking for a preset time (for example, 3 to 5 minutes) for complete solidification. do.

At this time, if the coagulant powder is added after putting soybean water inside the tofu container, the coagulant is not uniformly mixed, so the coagulation power is lowered.

In the present invention, it is preferable to use two coagulation methods in order to solve this problem. First, put the coagulant diluted coagulant powder mixed with some water or soybean water in the inside of the tofu container, and then put the prepared soybean water inside the tofu container. could be better

Also, secondly, if you put soybean water inside the tofu container first, and then put a coagulant diluent mixed with a little water or soybean water in a coagulant powder in a separate container, the coagulant and the soybean water are evenly mixed and diluted, so coagulation can be better .

At this time, the reason that the temperature of soybean water should be maintained at 85°C or higher is because it was found through self-experiment that the temperature of soybean water was uniformly solidified at 85°C or higher, but did not solidify well below 85°C.

6. Sundubu or whole tofu manufacturing step (S60)

Afterwards, the user can complete the soft tofu or the whole tofu.

When a user makes soft tofu, after mixing the coagulant and soybean water, after 3 to 5 minutes, when the soybean water solidifies into a lump, scoop it out with Utmul to complete the soft tofu.

On the other hand, if the user makes all-bubble, mix the coagulant and soybean water, and after 3 to 5 minutes, scoop out the clear water from the top of the tofu container and discard the protein coagulated product that has settled at the bottom. After pouring, close the lid and press it with a pressing stone, and the water will drain out of the small hole in the tofu molding container to complete the whole part.

At this time, when the tofu is hardened enough, put the tofu molding container in the water, remove the box from the water, and soak the tofu in water for a while. This will drain all the excess coagulant and improve the flavor of the tofu.
