The present invention relates to a soft tofu manufacturing apparatus and a soft tofu manufacturing method, and more particularly, to a soft tofu manufacturing apparatus and a soft tofu manufacturing method for producing a soft tofu germinated by using filtered filtrate filtered deep sea water.

As modern people's attention has been focused on health, well-being foods processed using natural ingredients and pollution-free natural foods are attracting attention. Among these health foods, tofu is a well-being food that has been handed down since the Goryeo Dynasty. Soybean is used as a main ingredient, so it is rich in protein and unsaturated fatty acids, and has high amino acid content. In addition, the zenithine component contained in soybeans has the effect of preventing adult diseases such as hypertension, arteriosclerosis, and inhibits the promotion of cancer, and the tocopherol component has the effect of preventing aging. Pure tofu processed into such beans as a raw material is generally produced through a manufacturing process as shown in FIG.

1 is a flow chart illustrating a conventional method for manufacturing soft tofu. As shown in Figure 1, the method for producing a soft tofu is first started from the operation of selecting and washing the beans (S10). The soybeans used to make tofu should be washed cleanly, and this washing process may delay the deterioration of the tofu and reduce the heat-resistant bacteria of the soybean.

Since the washed beans are soaked in water to facilitate the extraction of soy milk during grinding (S20). If the so-called soybean is too long, the protein component is eluted in water and the nutrients of the soybean are lost. If the so-called is so short, the amount of soymilk that can be extracted during crushing of soybean is reduced. The time to call the beans depends on the temperature and the amount of sunshine, so it is important to set the right time. The soybeans are then crushed by a grinder, filtered and separated into soy milk and bean curd (S30).

Since the soy milk is separated from the busy to sterilize the digestive disorders contained in the bacteria and soy milk mixed (S40). Subsequently, a coagulant (potassium sulfate, magnesium chloride, calcium chloride, gluconodeltalactone, etc.) is added to the heated soymilk to solidify the liquid soymilk (S50). At this time, the soy milk in the solidified state is defined as a soft tofu and when the soy milk in this state is pressed, tofu is formed.

However, this process of manufacturing tofu has the problem of missing nutrients because it uses only soy milk to make soy milk by separating soy milk and sesame, and some of the nutrients contained in soybeans are damaged during various processes to produce soy tofu. Therefore, there is a need to replenish damaged nutrients.

The washed beans are then filtered in deep water to remove the deep seawater so that duss (bean sprouts) germinate (S120). At this time, in order to promote germination of beans,

Has a bactericidal effect for hygienic management of germinated environment

Can be supplied. Soybean sprouts from beans are the most nutritious when they are within 10cm long, and you can grow bean sprouts to consume mineral-rich bean sprouts.

Filtrate water used when germinating soybean is water extracted from deep sea water, and the process of extracting the filtered water from deep sea water will be described in detail with reference to FIG. 4. The deep seawater from which the filtrate is extracted is seawater that flows over 200M deep seawater, so no phytoplankton consuming nutrients because sunlight cannot reach it.

For this reason, deep sea water is rich in inorganic nutrients necessary for plant growth, such as nitrogen, phosphorus, and silicic acid, which are broken down by bacteria, and minerals (magnesium, calcium, sodium) that help cells work 2-20 times more than regular drinking water. It is rich in nutrition because it contains more. Therefore, germinating soybeans with filtered deep seawater can not only absorb various nutrients contained in deep seawater but also obtain various vitamins and ingredients such as phosphorus, iron, calcium, and fiber at the same time. You can make nutritious, healthy tofu.

4 is a flowchart illustrating a process of extracting filtrate from deep sea water, and FIG. 5 is a block diagram illustrating a reverse osmosis machine used in a reverse osmosis process of the filtrate extraction process of FIG. 4.

In order to manufacture the filtered water, first, the deep sea water is taken with a water intake pump and heated to about 20 to 30 ° C. (S200).

At this time, when the deep sea water is warmed, the filtration efficiency increases during deep sea water filtration as the water temperature rises. Subsequently, the warmed deep sea water is filtered with a micro filter, ultra filter, or the like to remove suspended substances causing turbidity (S210).

Subsequently, the filtered deep sea water is nanofiltered with a nanofilter to discharge sulfuric acid ion-containing mineral water not filtered by the nanofilter (S220).

The desulfurized ionized saline filtered by the nanofiltration membrane is not filtered by the demineralized water and the reverse osmosis membrane (330 (see FIG. 5)) in which the salt is removed by reverse osmosis by a reverse osmosis membrane of the reverse osmosis machine (300, see FIG. 5). Not separated into concentrated mineral brine (S230).

At this time, the desulfurized ion brine filtered from the nanofiltration membrane is introduced into the reverse osmosis unit 300 shown in FIG. Reverse osmosis unit 300 is the solvent is water is filtered, the salt component of the solute is not reverse osmosis membrane 330, desulfurization ion brine storage unit 310, the desulfurization ion brine is stored, fresh water storage for fresh water Part 320 is made.

When the desulfurized ionized saline is introduced into the desulfurized ionized saline storage unit 310, and the freshwater is introduced into the freshwater storage unit 320, the desulfurized ionized salt solution having a high concentration due to reverse osmosis is directed toward the freshwater storage unit 320. The reverse osmosis membrane 330 does not pass through the solute of the salt component and passes only water as a solvent, thereby obtaining demineralized water from which the salt is removed. If the salt component remains in the demineralized water, the reverse osmosis process can be repeated to obtain the demineralized water from which the salt component is completely removed.

Subsequently, the demineralized water from which the salt is completely removed is subjected to a beverage preparation process, and the concentrated mineral brine is separated into the demineralized mineral water and the concentrated brine from which the salt is removed through electrodialysis (S240).

At this time, the concentrated brine is formed into a salt through a salt manufacturing process and can be extracted from the salt water, and the mineral balance can be prepared by adjusting the mineral balance by mixing the processed demineralized water that has undergone the beverage preparation process with the demineralized mineral water. (S250).

Thereafter, after adjusting the pH of the processed demineralized water after the beverage preparation process, the mineral water and the mineral balance adjusting solution are mixed to control the hardness of the filtered water to be used for germination of the beans (S260). Hardness is a value that indicates the content of minerals (calcium and magnesium salts) contained in water.

Soybean germinated by the thus produced filtered water is washed to remove the shell (S130). At this time, if the peel of the beans is removed, the powder efficiency during the grinding of the beans is increased.

Soybean with the bean sprouts in the peeled state is dried at a low temperature of 5 ~ 10 ℃ higher temperature than the atmosphere to be easily crushed (S140). Then, the beans dried by the low temperature drying method are pulverized in the first mill 161 and the second mill 162 to form a powder having fine particles (S150). At this time, the beans are first crushed into predetermined particles by the coarse crusher and secondly crushed by the ultrafine crusher.

Thereafter, the soybean powder pulverized into ultrafine particles by a mixer is mixed with filtered water, and salt is added to form a tofu preparation liquid, and the formed tofu preparation liquid is heated (S160). When the mixed soft water extracted from the salt is mixed with the heated soft tofu preparation liquid and the soft tofu preparation liquid is solidified, the soft tofu is produced (S170). At this time, the added salt is extracted by drying the concentrated brine can be used to extract the salt from the salt. In addition, tofu can be manufactured by pressing the soft tofu for a predetermined time at a predetermined pressure.

The soft tofu prepared by this method is different from the conventional method, namely, tofu, which is made using only soy milk and high-protein ingredients and vitamin B1, vitamin B2, vitamin E, linoleic acid, calcium, and dietary fiber. It's richer in minerals, soybean nutrients, and soybean nutrients, making it richer than traditional tofu.

The soft tofu manufacturing apparatus and the soft tofu manufacturing method according to the present invention as described above germinates soybeans with filtered water filtered from deep seawater, rich in nutrients by minerals and deep nutrients contained in deep seawater, and soybeans are dried whole. Because it is crushed to make it effective to replenish nutrients damaged during manufacture.
