Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a fully automatic energy-saving rice soaking system. Background Technology

[0002] The production process of rice starch first involves soaking and draining the rice. The soaking process requires a large amount of tap water, while the draining process generates a large amount of wastewater. Typically, the rice soaking tanks are quite tall, and the soaking and draining processes are at different operating levels, requiring workers to frequently cross floors to operate, resulting in extremely low production convenience. In addition, a large amount of wastewater generated from rice draining is discharged as sewage, which increases the difficulty of sewage treatment and, consequently, sewage treatment costs.

[0003] In other words, traditional rice soaking processes have two major drawbacks. One is that they rely on manual operation, which leads to water waste, low efficiency, and difficulties in hygiene control. The other is that while existing equipment can automate the rice soaking process, it lacks a closed-loop water circulation system, resulting in significant water waste. Utility Model Content

[0004] This application addresses the shortcomings of the prior art by providing a fully automatic energy-saving rice soaking system that integrates rice soaking, separation, conveying, water filtration and recycling, thereby solving the problems of water waste and reliance on manual labor.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A fully automatic energy-saving rice soaking system, characterized in that it includes:

[0007] The fixed supports set up on the site are used as the installation base;

[0008] The rice soaking container, mounted on top of a fixed support, is used as the container for the rice soaking process.

[0009] The rice-water separator connected to the bottom opening of the rice soaking tank is used to separate the rice-water mixture;

[0010] A conveyor belt, connected to the discharge end of the rice-water separator, is used to transport soaked rice that has been filtered by the rice-water separator.

[0011] The filtered water recovery tank is connected to the liquid outlet of the rice-water separator to collect the filtered water separated by the rice-water separator.

[0012] A filtration system is arranged between the water recovery tank and the rice soaking tank to purify the water in the water recovery tank and circulate it through the rice soaking pipe.

[0013] The control cabinet is installed at any location within the site and is connected to the electrical actuators configured within the system.

[0014] Furthermore, the rice-water separator includes a sealed container connected to the bottom opening of the rice soaking tank, a water-filtering screen disposed inside the sealed container, and the bottom of the sealed container has a discharge end and a liquid discharge end. The discharge end discharges to the top of the conveyor belt through a discharge pipe, and the liquid discharge end discharges to the direction of the water-filtering recovery tank through a drain pipe.

[0015] Furthermore, a second pneumatic butterfly valve is installed on the path of the discharge end connected to the discharge pipe, a first pneumatic butterfly valve is installed on the path of the liquid outlet end connected to the drain pipe, and a flow meter is also installed on the path of the drain pipe.

[0016] Furthermore, a pressure sensor is also installed at the bottom of the rice soaking container to monitor the amount of water inside the container.

[0017] Furthermore, a drain pneumatic valve is installed at the bottom of the water filtration recovery tank, and a level gauge and a tap water supply valve are installed on both sides above it. A pH meter is also installed inside the water filtration recovery tank.

[0018] Furthermore, the filtration system includes a pneumatic outlet valve located at the bottom of the water recovery tank. The pneumatic outlet valve is connected to a centrifugal pump, and the outlet end of the centrifugal pump is connected to a pneumatic three-way valve. The pneumatic three-way valve includes a first outlet and a second outlet. The first outlet is connected to the top of the rice soaking tank via a return water pipe, and the second outlet is connected to a filter module. The filter module is connected to the top of the water recovery tank via a filter outlet.

[0019] Furthermore, the filter module includes a first filter and a second filter connected in sequence.

[0020] The advantages of this utility model over the prior art are as follows:

[0021] I. Closed-loop circulation: The closed-loop circulation system consists of a centrifugal pump, a pneumatic three-way valve, and a filter water recovery tank. The pneumatic three-way valve switches the working state. When the water in the rice soaking tank has not reached the set amount, the pneumatic three-way valve controls the valve to switch to the first outlet, and the water in the filter water recovery tank is delivered to the rice soaking tank. When the water in the rice soaking tank reaches the set amount and the rice soaking process is completed, the pneumatic three-way valve automatically switches to the second outlet, and the filtered water is circulated through the first or second filter to the filter water recovery tank for filtration.

[0022] 2. Flow monitoring to check if the soaked rice is drained: When the flow meter shows 0, the second pneumatic butterfly valve automatically closes, the system assumes that the soaked rice and water have been separated, the first pneumatic butterfly valve opens, and the soaked rice can enter the conveyor belt.

[0023] 3. Automatic sewage discharge: The filter water recovery tank is equipped with a pH meter. When the pH of the filtered water decreases by 0.5 compared to the set value, the pneumatic drain valve at the bottom of the filter water recovery tank will automatically open to discharge sewage, thereby ensuring the cleanliness of the rice water in the entire system and reducing the risk of microbial contamination.

[0028] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0029] This invention provides a fully automatic energy-saving rice soaking system, which aims to solve the problems of water waste and low automation caused by the lack of a closed-loop water circulation system in existing rice soaking systems.

[0030] like Figures 1 to 3 As shown, this utility model includes a fixed support 2 installed on the site, which serves as the installation base; a rice soaking tank 1 installed on top of the fixed support 2, which serves as the container for the rice soaking process; a rice-water separator 27 connected to the bottom opening of the rice soaking tank 1, which is used to separate the rice and water mixture; a conveyor belt 8 connected to the discharge end of the rice-water separator 27 for conveying the soaked rice filtered by the rice-water separator 27; a filter water recovery tank 26 connected to the liquid outlet end of the rice-water separator 27 for collecting the filtered water separated by the rice-water separator 27; a filtration system arranged between the filter water recovery tank 26 and the rice soaking tank 1 for purifying the filtered water in the filter water recovery tank 26 and circulating it to the rice soaking pipe; and a control cabinet 7 installed at any location on the site and connected to the electrical actuators configured in this system.

[0031] In one embodiment of this utility model, the rice-water separator 27 includes a sealed container 9 connected to the bottom opening of the rice soaking tank 1, a water filter screen 10 disposed inside the sealed container 9, the bottom of the sealed container 9 having a material outlet end and a liquid outlet end, the material outlet end discharging outwards to the conveyor belt 8 through a material outlet pipe 6, and the liquid outlet end discharging outwards to the water filter recovery tank 26 through a drain pipe 12.

[0032] In one embodiment of this utility model, a second pneumatic butterfly valve 11 is provided on the path of the discharge end connected to the discharge pipe 6, a first pneumatic butterfly valve 4 is provided on the path of the liquid outlet connected to the drain pipe 12, and a flow meter 5 is also provided on the path of the drain pipe 12.

[0033] In one embodiment of this utility model, a pressure sensor 3 for monitoring the amount of water in the rice soaking container 1 is also provided at the bottom.

[0034] In one embodiment of this utility model, a drain pneumatic valve 24 is provided at the bottom of the water filter recovery tank 26, and a level gauge 23 and a tap water supply valve 15 are respectively provided on the upper two sides. A pH meter is also provided inside the water filter recovery tank 26.

[0035] In one embodiment of this utility model, the filtration system includes a pneumatic outlet valve 16 disposed at the bottom of the water recovery tank 26. The pneumatic outlet valve 16 is connected to a centrifugal pump 17. The liquid outlet end of the centrifugal pump 17 is connected to a pneumatic three-way valve 18. The pneumatic three-way valve 18 includes a first outlet 19 and a second outlet 20. The first outlet 19 is connected to the top of the rice soaking tank 1 through a return water pipe 25. The second outlet 20 is connected to a filter module. The filter module is connected to the top of the water recovery tank 26 through a filter outlet 14.

[0036] In one embodiment of this utility model, the filter module includes a first filter 21 and a second filter 22 connected in sequence.

[0037] The specific structure and working principle of this utility model are as follows:

[0038] In terms of structure, the preferred embodiment can be: the rice-water separator 27 includes a sealed container 9, a water filter screen 10, a first pneumatic butterfly valve 4, a second pneumatic butterfly valve 11, a drain pipe 12, and a discharge pipe 6. When the rice soaking is finished, the rice-water mixture passes through the water filter screen 10, effectively separating the rice and water. At this time, the discharge pipe 6 does not discharge, the first pneumatic butterfly valve 4 is opened, the filtered water flows out through the drain pipe 12, and the soaked rice is retained in the sealed container 9.

[0039] Rice starch production uses broken rice as raw material. The particle size of broken rice is usually between 8 and 20 mesh. Therefore, the sieve of the water filter screen 10 is designed with a mesh size of 20 to effectively avoid the loss of broken rice.

[0040] The water recovery filtration system mainly consists of a centrifugal pump 17, a pneumatic three-way valve 18, a first filter 21, and a second filter 22. The first filter 21 and the second filter 22 form a dual filter system, with one in use and one on standby, thus ensuring the continuity of the recovery filtration system. The filter screens are designed with 40 mesh openings, which can effectively filter impurities in the water.

[0041] When using:

[0042] First, after the rice feeding is completed, start the rice soaking button on the PLC control cabinet 7. The pneumatic valve 16 of the water outlet of the water recovery tank 26 will open automatically, the centrifugal pump 17 will start automatically, and the pneumatic three-way valve 18 will switch to the first water outlet 19. The water from the water recovery tank 26 will be transported to the rice soaking tank 1.

[0043] When the water level in the rice soaking tank 1 reaches the set level, the pressure sensor 3 is linked with the centrifugal pump 17, the water filter recovery tank 26, and the water outlet pneumatic valve 16. The centrifugal pump 17 and the pneumatic valve are closed, and the PLC control cabinet 7 starts the rice soaking timer according to the set soaking time.

[0044] After the rice is soaked, the first pneumatic butterfly valve 4 on the water filtration pipeline opens automatically, and the filtered water flows through the flow meter 5 to the water filtration recovery tank 26. The centrifugal pump 17 starts automatically, and the pneumatic three-way valve 18 switches automatically to the second outlet 20. The filtered water then passes through the first filter 21 or the second filter 22 to the recovery tank for circulation filtration.

[0045] The flow rate change of flow meter 5 indicates whether the soaking water has been drained. When the flow rate on flow meter 5 is 0, the first pneumatic valve 4 automatically closes, indicating that the soaking water has been separated and the soaked rice can proceed to the next stage. At this time, conveyor belt 8 starts automatically, and the second pneumatic butterfly valve opens after a 5-second delay. The soaked rice passes through the discharge port onto conveyor belt 8 for further processing.

[0046] The second pneumatic butterfly valve opens after a 5-second delay following the start of conveyor belt 8. This is to ensure that the soaked rice is smoothly transported to the next stage and to prevent spillage.

[0047] The water recovery tank 26 is equipped with a tap water supply valve 15, which can replenish the water lost each time the rice is soaked; at the same time, the water recovery tank 26 is also equipped with an overflow port to prevent the water level from being too high and overflowing.

[0048] The filtered water contains a small amount of starch. Over time, the filtered water will ferment and turn sour, requiring replacement of the rice soaking water. Therefore, the filtered water recovery tank 26 is equipped with a pH meter. When the pH of the filtered water drops by 0.5 compared to the set value, the pneumatic drain valve 24 at the bottom of the filtered water recovery tank 26 will automatically open to discharge wastewater, thereby ensuring the cleanliness of the rice soaking water in the entire system and reducing the risk of microbial contamination.

[0049] Once the rice soaking time is set, the entire system can be started automatically with just one button, greatly improving production efficiency and reducing the labor intensity of workers. It also significantly reduces the discharge of soaking water, thus lowering wastewater treatment costs.
