Problems solved by technology

[0002] Most of the production process of soy milk is heated to a predetermined temperature range at full power to start beating, and the motor drives the crushing tool to rotate to crush the material. Taking dry beans as an example, due to the short heating time in the early stage, the temperature rises quickly and the skin of the dried beans There is inconsistency with the water absorption and expansion of the cotyledon, so air will be generated between the epidermis and the cotyledon. Due to the low density of the air, it is easy to make soybeans float on the water surface, thereby affecting the crushing efficiency. In addition, dry beans cannot be fully obtained in the prior art. Soaking and softening makes dried beans hard, so in the early stage of the whole pulping process, the noise of the soybean milk machine is relatively loud, and the maximum noise is greater than 85dB(A). It is the main source of noise, and this noise is not easy to reduce through the optimization of the crushing structure of the soybean milk machine

Embodiment approach 1

[0027] A noise-reducing pulping method, providing a cup body, a motor, a crushing cutter and a heating device, at least including the following stages:

[0028] (a) Preheating and soaking stage: the heating device heats the water and materials in the cup body, and heats it to above 70°C at a temperature rise rate of 3°C / min to 10°C / min, and enters the next stage;

[0029] (b) Crushing stage: the motor drives the crushing tool to rotate and crush the water and materials in the cup to form a slurry, and enter the next stage;

[0030] (c) Boiling stage: the heating device heats the slurry in the cup until it is cooked.

[0031] In this embodiment, the preheating and soaking stage is accompanied by a stirring step in which the motor drives the pulverizing cutter to rotate.

[0032] In this embodiment, the crushing stage includes the step of the motor driving the crushing tool to rotate and crush and the step of stopping the motor. The motor operation and the motor stop are cycled...

Embodiment approach 2

[0036] The difference between the second preferred embodiment of the high-efficiency crushing and noise-reducing pulping method and the first preferred embodiment is that: in the preheating and soaking stage, the first temperature rise rate is 6 degrees Celsius / minute to 10 degrees Celsius It is heated to 70 to 85 degrees Celsius per minute, and then heated to above 85 degrees Celsius at a second temperature rise rate of 4 degrees Celsius / minute to 8 degrees Celsius / minute.

[0037] At the beginning, heat up to 70 to 85 degrees Celsius at a faster rate of temperature rise. This is because the water absorption efficiency of soybeans is not high when the temperature is low, and the soaking and softening efficiency of soybeans can be improved by rapidly heating to a higher temperature. The applicant Studies have found that heating at 6°C / min to 10°C / min at the beginning can ensure that soybeans are fully soaked and at the same time improve the soaking and softening efficiency, and...

Embodiment approach 3

[0042] The difference between the third preferred embodiment of the high-efficiency crushing and noise-reducing pulping method is different from the first preferred embodiment in that: the crushing stage includes a coarse crushing stage and a fine crushing stage, and the coarse crushing stage includes a motor driving a crushing cutter The step of rotating and the step of stopping the motor, the motor working and the stopping of the motor are carried out sequentially, and the gap heating device where the motor stops is heated at a heating rate of 2 degrees Celsius / minute to 5 degrees Celsius / minute; the fine crushing stage includes the motor driving the crushing tool to rotate The step of step and the step of motor stop, motor operation and motor stop cycle in sequence, and the gap heating device where the motor stops is heated at a heating rate of 1°C / min to 4°C / min. In this way, in the process of coarse crushing, the contact area of ​​soybeans with water is increased, which ca...

Abstract

The present invention relates to a high-efficiency crushing and noise-reducing pulping method, which at least includes the following stages: (a) preheating and soaking stage: the heating device heats the water and materials in the cup body at a rate of 3 degrees Celsius to 10 degrees Celsius per minute. The temperature rise rate per minute is heated to the preset temperature, and the preset temperature is not lower than 70°C, and enters the next stage; (b) crushing stage: the motor drives the crushing cutter to rotate and crush the water and materials in the cup to form a slurry , enter the next stage; (c) boiling stage: the heating device heats the slurry in the cup until it is cooked. Compared with the prior art, the technical solution of the present invention makes the water absorption rate and expansion rate between the skin and the cotyledons of soybeans have a better consistency, so that the soybeans can fully absorb water and swell, improve the crushing efficiency and at the same time can Play the role of noise reduction.
