Description

Technical Field

[0001] This utility model belongs to the field of brine feeding technology, specifically relating to a brine quantitative feeding system. Background Technology

[0002] In food processing, chemical production, and other fields, the precise quantitative addition of brine and koji (fermented rice) is crucial for ensuring product quality and process stability. Traditional brine addition methods often rely on manual operation, which is inefficient, inaccurate, and poses certain safety hazards. Similarly, koji addition faces similar problems. Manual addition is not only time-consuming and labor-intensive but also prone to inaccurate dosage, affecting product quality and the uniformity of the fermentation process.

[0003] Traditional manual feeding methods require a large amount of manpower, resulting in low efficiency and failing to meet the high-efficiency demands of modern production. Manual feeding also makes it difficult to guarantee precise material quantities, easily leading to inconsistencies in product quality and impacting production standards. Furthermore, workers may be directly exposed to high temperatures or corrosive substances during manual feeding, posing certain safety hazards. Traditional feeding methods may also generate noise and vibration, affecting the comfort of the working environment.

[0004] To address the aforementioned shortcomings, a design scheme for an intelligent brine quantitative feeding system and a koji quantitative feeding module is proposed. The aim is to achieve precise quantitative feeding of brine and koji through automated control technology, thereby improving production efficiency and product quality. Simultaneously, the system design considers factors such as ease of operation, convenient maintenance, and safety to meet the needs of modern production. Utility Model Content

[0005] The present invention aims to solve the technical problem of low efficiency caused by the manual feeding method used in the prior art for quantitative feeding of brine, which requires a large amount of manual operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a brine quantitative feeding system, comprising a brine buffer tank, a brine feeding module, and a koji quantitative feeding module. The brine buffer tank supplies brine to the brine buffer pipeline via a water supply pump; it is used to prepare brine at approximately 19°Bé and maintain the brine pressure in the brine buffer pipeline at approximately 0.4 MPa; the brine feeding module is used to feed the brine from the brine buffer pipeline into the drying vat, and the koji quantitative feeding module is used to quantitatively feed koji into the drying vat; the brine and koji are quantitatively fed into the drying vat separately by a brine quantitative feeding vehicle and a koji pneumatic conveying device for fermentation.

[0007] The brine feeding module includes a brine metering trolley, a connecting hose, a feeding port, and a control box A. The worker pushes the brine metering trolley to the drying tank, connects the brine buffer pipe to the brine metering trolley inlet with the connecting hose, sets the brine feeding amount through the control box A, and presses the start button to feed the brine.

[0008] The quhuang quantitative feeding module includes a weighing forklift, a feeding trolley, a control box B, and a quhuang pneumatic conveying mechanism. After setting the quhuang feeding amount through the control box B, the start button is pressed to feed the quhuang. The quhuang pneumatic conveying mechanism is used to transport the quhuang in the feeding trolley to the drying tank.

[0009] Preferably, the brine buffer tank is connected to the brine buffer pipeline via a feed pipe, and the water supply pump is installed on the feed pipe.

[0010] As a preferred option, the brine buffer pipeline is equipped with several valves for discharging brine.

[0011] As a preferred embodiment, the brine metering trolley is equipped with a feeding pipe on top, with an inlet at one end and a feeding port at the other end. An inlet control valve and a flow meter are provided on the end of the feeding pipe near the inlet, and a feeding control valve is provided on the end of the feeding pipe near the feeding port. The feeding port is connected to the drying tank through a feeding long pipe A.

[0012] Preferably, the feeding pipe is installed and fixed on the top of the brine metering cart via a pipe support.

[0013] Preferably, control box A is fixed on the mounting bracket on the top of the brine metering cart.

[0014] As a preferred option, the saline dispensing cart is also equipped with a handle.

[0015] As a preferred embodiment, the Quhuang pneumatic conveying mechanism includes a feeding pipe B, a Roots blower installed on the feeding pipe B, a pressure gauge, a shock absorber, and an accelerator. The discharge port at the bottom of the hopper on the feeding trolley is connected to a rotary valve driven by a motor, and the rotary valve is connected to the inlet of the accelerator on the feeding pipe B.

[0016] Start the Roots blower to create a stable airflow in the feeding pipe B, which will draw the material from the hopper into the rotary valve. Turn on the motor and adjust the frequency to ensure that the material enters the feeding pipe B stably and then enters the drying cylinder through the feeding pipe B.

[0017] As a preferred option, the Roots blower is equipped with a silencer.

[0018] Compared with the prior art, the technical effects and advantages of this utility model are:

[0019] 1. This brine metering system uses a brine buffer tank to store pre-adjusted brine. A water pump delivers the brine to the buffer pipeline to maintain stable pressure. The brine flow rate to the metering trolley is controlled by valves. Workers push the trolley to the drying cylinder, connect the hose, and set the feeding amount via the control box. After startup, the flow meter and valves control the brine flow rate to ensure accurate feeding. Control box B sets the feed amount for the bentonite. After startup, the Roots blower generates a stable airflow, which is controlled by a rotary valve to control the flow rate of the bentonite into the long pipe. Motor frequency adjustment ensures stable entry, and finally, the brine enters the drying cylinder.

[0020] 2. Both modules can precisely control the amount of feed, ensuring product quality and uniformity of the fermentation process. The system has a high degree of automation, reducing manual operation, improving efficiency and reducing errors. Automation reduces manual operation time, increases production efficiency, shortens the production cycle, reduces physical labor, lowers labor intensity and physical exertion, reduces the risk of workers being exposed to harmful substances, improves workplace safety, and precisely controls the feeding speed, avoiding pipe blockage and material waste, thus improving material utilization.

[0021] 3. Shock absorbers and silencers reduce vibration and noise, improving working environment comfort. The equipment is adjustable to adapt to different production needs and material characteristics. An orderly shutdown process ensures complete material delivery, simplifies shutdown operations, and improves production efficiency. Operators only need to set the feed rate through the control box, making operation simple and easy to learn. The trolley is equipped with handles for easy worker pushing, enhancing system flexibility and adaptability.

[0022] 4. In summary, the design and implementation of this brine quantitative feeding system and quhuang quantitative feeding module bring many benefits, including improved feeding accuracy, automation level, production efficiency, safety, material utilization rate, and working environment comfort, providing strong support for modern production.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The following combination Figures 1 to 3 This application will be described in further detail.

[0029] This application discloses a brine quantitative feeding system, including a brine buffer tank 1, a brine feeding module 6, and a koji quantitative feeding module 7. The brine buffer tank 1 supplies brine to a brine buffer pipe 4 via a water supply pump 3; it is used to prepare brine at approximately 19°Bé and maintain the brine pressure in the brine buffer pipe 4 at approximately 0.4 MPa. The brine buffer tank 1 is connected to the brine buffer pipe 4 via a feed pipe 2, and the water supply pump 3 is installed on the feed pipe 2. Several valves 5 are evenly distributed on the brine buffer pipe 4 for discharging brine. The brine feeding module 6 is used to feed the brine from the brine buffer pipe 4 into a drying tank 8, and the koji quantitative feeding module 7 is used to quantitatively feed koji into the drying tank 8. The brine and koji are quantitatively fed into the drying tank 8 separately by a brine quantitative feeding vehicle and a koji pneumatic conveying device for fermentation.

[0030] The brine feeding module 6 includes a brine metering cart 61, a connecting hose 62, a feeding port 63, and a control box A64. The worker pushes the brine metering cart 61 to the drying tank 8, connects the brine buffer pipe 4 to the brine inlet 66 of the brine metering cart 61 through the connecting hose 62, sets the brine feeding amount through the control box A64, and presses the start button to feed the brine.

[0031] The brine metering cart 61 has a feeding pipe 65 on its top. One end of the feeding pipe 65 has a liquid inlet 66, and the other end has a feeding port 63. A liquid inlet control valve 67 and a flow meter 68 are located on the end of the feeding pipe 65 near the liquid inlet 66, and a feeding control valve 69 is located on the end of the feeding pipe 65 near the feeding port 63. The feeding port 63 is connected to the drying tank 8 via a feeding long pipe A610. The feeding pipe 65 is mounted and fixed to the top of the brine metering cart 61 via a pipe bracket 611. The control box A64 is fixed to the mounting bracket 612 on the top of the brine metering cart 61. The brine metering cart 61 also has a handle 613.

[0032] The brine metering module uses a control system to precisely control the brine flow rate, ensuring that a specific amount of brine is added to the drying tank 8. The brine buffer tank 1 stores pre-mixed brine, which is then pumped into the buffer pipe by the water supply pump 3, maintaining a stable pressure (approximately 0.4 MPa). Valves 5 are evenly installed on the brine buffer pipe 4 to control the flow rate of brine supplied to the metering cart. The worker pushes the brine metering cart 61 to the position of the drying tank 8 and connects the buffer pipe to the inlet 66 of the metering cart via a connecting hose 62. The control box A64 is used to set the volume of brine to be added, and the system is started via a button on the control box. The inlet control valve 67 and the flow meter 68 work together to control the brine flow rate entering the metering cart according to the set amount. The feeding control valve 69 adjusts the brine flow rate, allowing the brine to enter the drying tank 8 from the feeding port 63 through the feeding long pipe A610.

[0033] The flow meter 68 and control system enable precise quantitative feeding of brine, ensuring uniformity in the fermentation process and consistency in product quality. Workers simply set the feeding amount via the control box A64, making operation simple and easy to learn. Automated feeding reduces manual operation time and improves production efficiency. Precise quantitative feeding reduces raw material waste, contributing to cost savings. Workers are no longer required to manually feed brine, reducing physical labor. Automated feeding lowers the risk of worker exposure to hazardous substances, improving workplace safety. The brine metering cart 61 is equipped with a handle 613 for easy maneuvering, enhancing the system's flexibility and adaptability. The entire system is designed for ease of maintenance and cleaning, helping to keep the equipment in good working order.

[0034] The Quhuang quantitative feeding module 7 includes a weighing forklift, a feeding trolley 71, a control box B72, and a Quhuang pneumatic conveying mechanism. After setting the Quhuang feeding amount through the control box B72, the start button is pressed to feed the Quhuang. The Quhuang pneumatic conveying mechanism is used to transport the Quhuang in the feeding trolley 71 to the drying tank 8.

[0035] The pneumatic conveying mechanism includes a feeding pipe B73, a Roots blower 74 mounted on the feeding pipe B73, a pressure gauge 75, a shock absorber 76, and an accelerator 77. The discharge port 78 at the bottom of the hopper on the feeding trolley 71 is connected to a rotary valve 710 driven by a motor 79. The rotary valve 710 is connected to the inlet of the accelerator 77 on the feeding pipe B73. A silencer 711 is mounted on the Roots blower 74. The accelerator 77 can be a DM200 / 150 model. The silencer 711 is a TROX-XBK-25S model.

[0036] Start the Roots blower 74 and run it at a stable speed to create a stable airflow within the feeding pipe B73. The material will then enter the rotary valve 710 from the hopper. Start the motor 79 and adjust its frequency to ensure a stable flow of material into the feeding pipe B73, which then enters the drying tank 8. Too fast a feeding speed will cause pipe blockage, while too slow a speed will affect conveying efficiency. The material slowly enters the accelerator 77 and, under the influence of the conveying airflow, flows through the pipe into the large tank. During the conveying process, observe the operating parameters of the Roots blower 74, such as current and air pressure, and pay attention to the flow of material within the pipe. After conveying is complete, stop the rotating device and wait until the material in the pipe has been mostly conveyed. Then, turn off the Roots blower 74 to stop the conveying system.

[0037] The operator can set the required feed rate of the Roots blower using the control box B72. Once set, pressing the start button will initiate the entire feeding process automatically. The Roots blower 74 is the core component, generating and maintaining a stable airflow within the feeding tube B73. This airflow is the driving force for material transport. The discharge port 78 at the bottom of the hopper on the feeding trolley 71 is connected to a rotary valve 710 driven by a motor 79. The rotary valve 710 controls the flow rate of material entering the feeding tube B73. The motor 79 adjusts the rotation speed of the rotary valve 710 via frequency modulation, thereby controlling the material's entry speed. Under the action of the rotary valve 710, the material slowly enters the accelerator 77 and is then carried into the feeding tube B73 by the airflow. The airflow transports the material to the drying cylinder 8. During the transport process, the operator needs to monitor the operating parameters of the Roots blower 74, such as current and air pressure, as well as the flow of material within the pipe, to ensure smooth transport. After transport is complete, the rotating device is stopped first, allowing the material in the pipe to be essentially transported. Then shut down the Roots blower 74 to stop the conveying system from working.

[0038] The Roots blower 74 provides a stable airflow, ensuring the uniformity and continuity of material transport. The frequency-adjustable motor 79 allows for speed adjustment to meet different production needs, preventing problems caused by excessively fast or slow feed rates. The shock absorber 76 reduces vibration during system operation, while the silencer 711 reduces noise pollution, improving working environment comfort. By observing the operating parameters of the Roots blower 74, such as current and air pressure, the status of the conveying system can be monitored in real time, allowing for timely adjustments. Using standard-model accelerators 77 and silencers 711 facilitates equipment maintenance and replacement, reducing maintenance costs. Stopping the rotating device before shutting down the Roots blower 74 ensures complete material transport, avoids material residue within the system, and simplifies the shutdown process.

[0039] In summary, the design of the Quhuang quantitative feeding module 7 optimizes the production process, improves production efficiency and product quality, and reduces production costs and safety risks.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
