Description

Technical Field

[0001] The invention relates to the field of bean product processing, in particular to a device for detecting and controlling moisture content of soybean soaking. Background Art

[0002] The main raw material for bean product processing is soybeans, and the first step of bean product processing is often to soak the soybeans. For example, when processing tofu and yuba, the washed soybeans must first be soaked for a period of time to make them suitable for grinding and the quality of tofu or yuba processing. The degree of soybean soaking is crucial for bean product processing, and it should not be soaked insufficiently or excessively. In the prior art, whether the soybeans are properly soaked depends entirely on manual judgment, that is, the soaked soybeans must be broken open and kneaded by hand at regular intervals to determine whether they are properly soaked. Obviously, this method of manual judgment is very blind and requires high experience from the operator.

[0003] The scientific method to judge whether the soybeans are properly soaked should be to test their moisture content. The moisture content of soybeans reaching the required level within a certain soaking time is also directly related to the pressure and water temperature. Therefore, developing a detection and control device that can continuously detect the moisture content of soybeans and then control the pressure and water temperature, so that the soybeans can be soaked for the best effect within the appropriate time (the soybeans cannot be soaked for too long, otherwise they will deteriorate), can not only improve the quality and yield of soybean products, but also save manpower. Summary of the invention

[0004] The purpose of the present invention is to provide a simple and practical method that can accurately detect the moisture content of soybeans during soaking, so as to control the pressure and temperature so that the best soaking effect can be achieved within a suitable time.

[0005] The above-mentioned object of the present invention can be achieved by adopting the following technical solutions.

[0006] The present invention comprises two parts: a soybean soaking facility and a detection and control circuit. The soybean soaking facility comprises a soybean soaking pool, a sampling basket, a gravity sensor, and a lifting mechanism; the detection and control circuit comprises a processor unit, a sensor and a detection unit, a control unit, a communication alarm unit, a power supply circuit, etc.

[0007] The soybeans to be soaked are placed in the soybean soaking pool, and a certain mass or volume of soybeans are placed in the sampling basket. The sampling basket with soybeans is placed on the soybeans in the soaking pool, and the soaking pool is filled with water and the sampling basket is buried. According to the set time interval, the lifting mechanism will lift the sampling basket and soybeans out of the water. During the process of the sampling basket being lifted out of the water, the gravity sensor detects its weight, and the detection and control program calculates the moisture content based on the detected weight and the initial weight before soaking. If it is difficult to meet the soaking requirements within the set time, the control circuit will increase the pressure by heating the water or raising the water level to meet the soaking requirements as soon as possible. After the soybean soaking meets the requirements, the system will issue a reminder alarm and send the information to the staff's mobile phone.

[0008] The above process does not require manual operation at all, and the detection and control are accurate, which not only saves manpower but also improves the output and quality of soy products. If it works in conjunction with other equipment developed by our company, it can also automatically control the addition of water and feeding, automatically drain water after soaking, and automatically transport the soaked soybeans to the pulping machine, fully realizing production automation.

DETAILED DESCRIPTION

[0010] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0011] The present invention provides a soybean soaking moisture content detection and control device, comprising a soybean soaking facility and a detection control circuit. The soybean soaking facility comprises a soybean soaking pool 1.1, a sampling net basket 1.2, a gravity sensor 1.3 and a lifting mechanism 1.4. The soybean soaking pool is used to contain soybeans and water, and a drainage outlet and a bean outlet can be set at the lower part thereof. Further, a turning device can be installed inside the bean soaking pool to turn the soybeans in the upper and lower parts to exchange positions to ensure uniform soaking. The sampling net basket is a mesh container for containing sampled soybeans. The sampled soybeans and the soybeans in the soaking pool are in the same soaking conditions. The weight of the sampled soybeans must be measured in advance before being placed in the soaking pool. According to the set time, the lifting mechanism will lift the sampling net basket together with the sampled soybeans from the water and measure the weight of the sampled soybeans after soaking during the lifting process. By comparing the weight before soaking, the program will calculate the moisture content after soaking; the detection control circuit comprises a processor unit 2.1, a sensor and detection unit 2.2, a control unit 2.3, a power supply circuit 2.4, and a communication and alarm unit 2.5. The sensor and detection unit includes a gravity sensor, a temperature sensor, a pressure or water level sensor and a detection circuit. The function is to detect the weight, water temperature and pressure of the sampled soybeans and upload the detection data to the processor unit after format processing. The function of the control unit is to raise and lower the lifting mechanism according to the set time, control the water temperature and water level (pressure). The function of the communication and alarm unit is to send a prompt alarm message after the soaking meets the requirements, and send the prompt message to the staff's mobile phone.
