In conclusion, the yoghourt is adopted as the strain to ferment and prepare the yoghourt, the whole yoghourt is of a left-right structure, the left side realizes the processes of grinding and boiling the soybean milk, the right side realizes the processes of feeding and fermenting, the soybean milk on the left side is conveyed to the cavity on the right side to ferment after the preparation of the soybean milk on the left side is finished, and the upper part on the right side is provided with the automatic yoghourt feeding device (namely the feeding mechanism). The whole body consists of a pulping system, a heating system, a yoghourt throwing system, a fermentation system, a control system, a conveying system and the like. All parts are controlled by a control system to work. The pulping system is positioned on the left side of the machine, and the cutter head and the motor are positioned at the bottom. The conveying system comprises a water pump, a filtering channel and a left cavity and a right cavity which are connected through a pipeline, and the soybean milk is extracted through the water pump and conveyed to the right side. The automatic yoghourt dispensing system comprises a yoghourt placing clamping groove and a puncture structure, the yoghourt placing clamping groove is of a standard size of a yoghourt cup, and the puncture structure can move in a telescopic mode. When the yoghourt needs to be added, the cross bar extends or rotates to move to the bottom of the yoghourt cup, and the upper end of the cross bar penetrates through the yoghourt cup to penetrate through the extension, so that the yoghourt flows into the fermentation cavity. The heating system is positioned at the bottom of the machine, the left side is heated with high power to control pulp boiling, and the right side is heated with low power to control fermentation.

Fig. 3 shows a schematic flow chart of a method for making sour soybean milk according to an embodiment of the present invention.

As shown in fig. 3, according to the method for preparing sour soybean milk of the embodiment of the present invention, the food processor as described in the above embodiment is used, and the specific method for preparing sour soybean milk comprises the following steps:

step S302, putting the strain on a feeding mechanism.

Specifically, the strain is preferably yogurt, such as yogurt cups with 100g of the strain, the fermentation time is shorter than that of the fermentation of the strain powder, the sour soybean milk fermentation acidic environment is provided by adding the yogurt, the strain fermentation speed is accelerated, the yogurt is easier to obtain by a user, the strain powder does not need to be purchased specially, the use is more convenient, and the strain activity is easier to maintain.

Step S304, adding the bean product and water into the soybean milk making body according to a preset soybean-water ratio, starting the soybean milk making component to grind the soybean milk, and starting the heating device to heat the soybean milk making body to boil the soybean milk so as to make soybean milk.

Specifically, the bean product is preferably soybean, wherein the preset ratio of soybean to water can be 1:7, namely 1400ml of water is added into 200g of soybean; the method is also suitable for food prepared by fermenting all vegetable proteins, such as soybean milk fermented by black beans or mixed with other coarse cereals; when grinding, the smaller the granularity is, the better the fermentation effect is.

And S306, starting the transmission device, and conveying the prepared soybean milk to a fermentation container.

And step S308, after the soybean milk in the fermentation container is cooled to the inoculation temperature, starting the feeding mechanism to feed strains into the soybean milk.

Wherein the inoculation temperature is preferably 45 ℃.

And S310, uniformly mixing the soybean milk and the strains in the fermentation container.

Step S312, when the temperature of the soybean milk mixed with the strain reaches the fermentation temperature, the heating device is started to heat the fermentation container, so that the soybean milk mixed with the strain is maintained at the fermentation temperature for a preset time period to complete fermentation to obtain the sour soybean milk.

Wherein, the fermentation temperature preferably takes the following value ranges: the preset time is preferably in the range of 40-43 ℃, and the preset time is preferably as follows: 5 to 8 hours.

In this embodiment, when making the sour soybean milk, the strain may be placed in the feeding mechanism of the fermentation container of the food processor in advance, and the mixture of the bean product and water with the preset ratio of bean water is added into the soybean milk making body to make the soybean milk, in the process of making the soybean milk, in order to make the prepared soybean milk more pure and ensure the edibility of the prepared sour soybean milk, the soybean milk is ground by the soybean milk making component and is heated by the heating device to boil the soybean milk, the soybean milk entering the fermentation container has a higher temperature after being transferred from the soybean milk making body to the fermentation container by the transmission device, in order to ensure the activity of the strain for fermenting the soybean milk, the soybean milk entering the fermentation container needs to be cooled, when the temperature of the soybean milk reaches the inoculation temperature of the strain, the feeding mechanism may be started to feed the strain into the soybean milk, and standing and fermenting for a first preset time under the condition that the temperature of the soybean milk mixed with the strains meets the fermentation temperature, and specifically heating the fermentation container by using a heating device to keep the fermentation temperature, so that the full-automatic production of the sour soybean milk is realized, and the method is simple, efficient and easy for user operation.

In one embodiment, 100g yogurt cups are placed in the designated location in advance, and soybeans and water are placed in the left-hand pulping chamber. After the program is started, the cutter head intermittently grinds the pulp at 10000r/min-20000r/min for 3 min-5 min, and simultaneously the bottom is controlled to heat, and the pulp is boiled for 15 min-20 min. After the pulping is finished, the soybean milk is conveyed to the right side fermentation cavity. And (5) entering a cooling stage, and stirring at a low speed by a stirring head at the bottom to accelerate cooling. When the temperature is reduced to 45 ℃, the cross rod of the puncture structure extends or rotates to move to the bottom of the yoghourt cup, the upper end extends to puncture the yoghourt cup, the yoghourt flows into the fermentation cavity, the stirring head is stirred at a low speed for 1-2 min and is uniformly mixed, then the mixture is kept stand for fermentation, the temperature is maintained at 40-43 ℃, the fermentation procedure is finished within 5-8 h, the preparation of the yoghourt is finished, and one of the specific processes is summarized as follows: feeding (200 g of soybeans and 1400ml of water), starting a program, grinding the soybean milk for 4min at 15000r/min, heating and boiling the soybean milk for 18min, after the soybean milk is finished, conveying the soybean milk to a fermentation cavity, cooling, stirring at a low speed of 100r/min by a stirring head at the bottom, automatically adding yoghourt (100g) when the temperature of the soybean milk reaches 45 ℃, continuously stirring at 100r/min by the stirring head for 2min, standing, and controlling the fermentation at 43 ℃ for 6 h.

The technical scheme of the invention is explained in detail by combining the drawings, and the food material management machine can realize full-automatic production of the sour soybean milk and is easy to operate by a user.
