Description

Technical Field

[0001] The invention relates to the technical field of rice processing detection, and in particular to an automatic rice processing precision detection device and method. Background Art

[0002] Rice is a finished product made from rice grains after cleaning, husking, milling, and finishing. Rice is one of the daily staple foods of the Chinese. As the world's largest rice producer and consumer, China has always had a great demand for rice; therefore, many Chinese people grow rice, and processing the mature rice grains into edible rice requires a lot of technology. Modern people are increasingly picky about the taste and quality of rice, so the rice processing methods also need to be continuously upgraded.

[0003] After the existing rice finishing process, the rice needs to be tested for moisture content (humidity). However, the existing rice processing precision automatic detection device still has shortcomings: only the rice can be tested. When the humidity is higher than the detection value after the test, the rice needs to be further dried and dehydrated, which is time-consuming and laborious to operate. At the same time, the processing efficiency is low, which greatly reduces the efficiency of rice processing. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the traditional automatic detection device for rice processing accuracy can only detect and process the rice but cannot process the rice according to the actual situation of the detection, and to propose an automatic detection device and method for rice processing accuracy.

[0007] As a further description of the above technical solution:

[0008] A feeding hopper is installed on the top of the feed box, a servo motor is installed on the front end surface of the feed box, and the output shaft of the servo motor is located inside the feed box and is drivingly connected to a material leveling disc.

[0009] As a further description of the above technical solution:

[0010] The material mixing plate has multiple groups of material storage troughs distributed in a circular array, and the vertical cross-sections of the multiple groups of material storage troughs are all in an isosceles triangle structure.

[0011] As a further description of the above technical solution:

[0012] Two groups of screen plates are symmetrically installed inside the feed box on both sides of the material mixing plate, and the inner surface walls of the screen plates are in contact with the outer surface walls of the material mixing plate.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the lifting belt is equidistantly fixed with multiple groups of lifting plates, and the outer walls of the multiple groups of lifting plates are in contact with the inner wall of the electric heating plate.

[0015] As a further description of the above technical solution:

[0016] The output end of the humidity sensor is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the input ends of the servo motor, the conveyor, the elevator, the first solenoid valve, the second solenoid valve and the electric heating plate respectively.

[0017] A method for automatically detecting rice processing accuracy comprises the following steps:

[0018] Step 1: Feeding: Add the rice to be tested into the feed box through the feeding hopper; the servo motor will drive the material mixing plate to rotate at a constant speed, and the multiple groups of storage troughs on the material mixing plate will rotate accordingly; when the storage trough moves to the top of the feed box, the rice will be evenly discharged into the storage trough, and when the storage trough moves to the bottom of the feed box, the rice will be evenly discharged into the feed box through the storage trough;

[0019] Step 2, detection: the numerical range of rice humidity detection is set by the controller; the sensor probe inside the detection tube will perform real-time humidity detection on the rice entering the detection tube, and transmit the humidity data of the rice to the controller, and the controller will analyze and calculate the humidity data; when the humidity of the rice is lower than and equal to the set value: it means that the water content of the rice meets the standard, the controller will control the second solenoid valve, the elevator and the electric heating plate to close, and control the servo motor, the conveyor and the first solenoid valve to open, and the detected rice will be discharged through the discharge pipe; when the humidity of the rice is higher than the set value: it means that the water content of the rice is high and does not meet the standard, the controller will control the servo motor and the second solenoid valve to close, and control the conveyor, the elevator, the second solenoid valve and the electric heating plate to open, and the rice will circulate between the detection tube, the guide tube and the lifting box, and the electric heating plate in the lifting box will dry and dehydrate the rice until the humidity data of the rice returns to the set value;

[0020] Step 3: Discharging: The conveyor drives the feeding screw to rotate forward, thereby conveying the rice that has been tested and dried inside the detection cylinder from left to right; when the rice moves inside the detection cylinder to the top of the discharge pipe, it will be discharged from the detection cylinder through the discharge pipe.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0022] 1. In the present invention, a detection and processing integrated structure is adopted. When the humidity of rice meets the set value, the rice will be discharged into the interior of the detection cylinder through the feed box, and the conveyor will drive the feeding screw to transmit, so as to transport the material to the discharge pipe for discharge. When the humidity of rice is higher than the set value, the second solenoid valve on the guide pipe will be opened, and the rice will enter the lifting box through the guide pipe under the action of the feeding screw. The lifting opportunity will drive the transmission roller to rotate, thereby driving the lifting belt to rotate clockwise, so as to transport the material to the electric heating plate. The electric heating plate will heat and dry the rice, so as to reduce the water content inside the rice. The dried and dehydrated rice will continue to enter the detection cylinder under the action of the lifting belt until the humidity of the rice meets the set value. This structure can automatically detect and process the rice. After the detection and processing, the rice can be selectively dried and dehydrated, which not only improves the efficiency of rice processing, but also improves the functionality of the detection device.

This structure can evenly feed the rice in the feed box into the detection cylinder, reducing the occurrence of rice accumulation, thereby improving the stability of rice detection and transportation.
