Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to an automatic feeding system for processing compound food seasonings. Background Technology

[0002] Currently, most seasoning processing and feeding equipment on the market suffers from limited functionality and insufficient automation. Traditional feeding devices rely heavily on manual assistance, which is not only labor-intensive and inefficient, but also prone to spillage and waste. Furthermore, it is difficult to ensure the uniformity of the feeding amount, which in turn affects the accuracy of subsequent seasoning formulation ratios and leads to fluctuations in product flavor.

[0003] Furthermore, seasoning ingredients are mostly in powder or granular form, possessing a certain degree of stickiness, and easily remain on the inner walls of the conveyor channel after feeding. Existing equipment generally lacks efficient cleaning and drying mechanisms, and long-term accumulation of residual ingredients can easily lead to moisture absorption, clumping, and spoilage. This not only contaminates the next batch of ingredients, causing product quality issues, but may also clog the conveyor channel, affecting normal equipment operation and increasing equipment maintenance costs. Meanwhile, although some equipment is equipped with a simple rinsing function, the rinsing water cannot be recycled, resulting in water waste and contradicting the principles of energy conservation and environmental protection in production.

[0004] Furthermore, the components of the existing feeding system have poor coordination. The feeding, cleaning, and drying processes often require manual switching and control, making it difficult to achieve automated process integration. This further reduces production efficiency, and manual control is prone to operational errors, affecting production continuity. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic feeding system for processing compound food seasonings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic feeding system for processing compound food seasonings includes a base with rollers, a feeding bin, a feeding assembly, a rinsing assembly, and a drying assembly. A rear support and a front support are fixedly installed on the upper end of the base. The feeding bin is fixedly installed on the upper end of the rear support, and a control panel is fixedly installed on the side wall of the feeding bin.

[0008] The feeding assembly consists of a feeding channel, a feeding auger plate, a drive mechanism, and a discharge port, and is used to feed raw materials during seasoning processing. The feeding channel is fixedly installed above the base, with its middle section fixedly connected to the front support and its rear section located below the discharge hopper and communicating with the opening below the discharge hopper. The feeding auger plate is rotatably connected inside the feeding channel, and the discharge port is located below the front end of the feeding channel and communicates with it.

[0009] The rinsing assembly consists of an infrared sensor, a water pump, a water tank, an inlet pipe, an outlet pipe, and a rinsing nozzle. It is used to rinse the feeding channel after feeding to ensure that there is no residue for the next feeding. A horizontal plate is fixedly installed on the upper end of the front bracket. The water pump is fixedly installed on the upper end of the horizontal plate. The infrared sensor is installed inside the feeding hopper to monitor the raw material in the feeding hopper. The water tank is fixedly installed inside the base. The inlet pipe is connected between the water pump and the water tank. The outlet pipe is connected between the water pump and the rinsing nozzle. The rinsing nozzle is fixedly installed on the top of the feeding channel with the water outlet penetrating into it. A device base is fixedly installed below the front end of the feeding channel. A control mechanism for controlling the opening and closing of the feeding port is installed on the device base. A return mechanism for recycling the rinsing water is installed on the water tank.

[0010] The drying assembly consists of a fan and an air duct, and is used to quickly dry the feeding channel after rinsing. The fan is fixedly installed on the upper end of the horizontal plate, and the air duct is connected between the fan and the feeding channel.

[0011] Preferably, the driving mechanism includes a drive motor and a pair of transmission wheels. The drive motor is fixedly mounted on the base by a fixing plate. One of the transmission wheels is coaxially fixedly connected to the output shaft of the drive motor. The other transmission wheel is rotatably mounted at the bottom of the feeding channel and coaxially fixedly connected to the feeding auger plate. The pair of transmission wheels are connected by a transmission belt.

[0012] Preferably, the control mechanism comprises a sealing plate, an electric push rod, a sliding block, and a connecting rod. The sealing plate is slidably connected to the lower end of the discharge port. The electric push rod is fixedly installed on the side wall of the device base, and a sliding groove is provided on the side wall of the device base. The sliding block is slidably connected in the sliding groove and fixedly connected to the telescopic end of the electric push rod. One end of the connecting rod is rotatably connected to the lower end of the sliding block, and the other end is rotatably connected to the lower end of the sealing plate.

[0013] Preferably, the reflux mechanism includes a reflux pipe and a filter screen. The reflux pipe is connected between the lower end of the feeding channel and the lower end of the water storage tank, and the filter screen is fixedly installed on the inner wall of the water storage tank and located above the reflux pipe.

[0014] Preferably, a first solenoid valve is installed at the connection between the return pipe and the feeding channel. The first solenoid valve is electrically connected to the control panel and controlled by an infrared sensor electrical signal.

[0015] Preferably, the air duct includes two parts: an air supply pipe and an exhaust pipe. The device base is a hollow cylinder with a semiconductor heating element fixedly installed inside. The air supply pipe is connected between the fan and one end of the device base, and the exhaust pipe is connected between the other end of the device base and the lower end of the feeding channel.

[0016] Preferably, a second solenoid valve is installed at the connection between the exhaust pipe and the feeding channel, and a humidity sensor is fixedly installed at the bottom of the feeding channel. The fan, the second solenoid valve, and the semiconductor heating element are all electrically connected to the control panel and controlled by the electrical signal from the humidity sensor.

[0017] Preferably, the inner wall of the feeding channel is provided with an anti-stick coating, the anti-stick coating is made of polytetrafluoroethylene, and the coating thickness is uniformly covering all areas of the inner wall of the feeding channel.

[0018] Preferably, the top of the feeding hopper is provided with an openable and closable sealing cover. The sealing cover is rotatably connected to the top edge of the feeding hopper via a hinge. The inner edge of the sealing cover is provided with an elastic sealing gasket. When the sealing cover is closed, it fits tightly against the top opening of the feeding hopper.

[0019] The present invention has the following beneficial effects:

[0020] 1. This invention achieves automatic raw material conveying by driving the feeding auger plate through the drive mechanism. In conjunction with the infrared sensor to monitor the raw material status of the feeding hopper and the control mechanism to automatically adjust the opening and closing of the feeding port, the entire process requires minimal manual intervention, effectively reducing labor intensity. At the same time, it avoids the problems of raw material spillage and waste and uneven feeding caused by manual operation, ensuring the accuracy of seasoning formula ratios and improving production continuity and overall efficiency.

[0021] 2. After the material is loaded, the rinsing component can be automatically activated. The water pump delivers clean water from the storage tank to the rinsing nozzle through the inlet and outlet pipes. The nozzle sprays water from all directions onto the inner wall of the material feeding channel, which can quickly wash away residual powdery or granular seasoning raw materials, preventing the raw materials from adhering to the channel for a long time and becoming damp, clumpy, or moldy. At the same time, the filter screen in the return mechanism can effectively filter the raw material impurities in the rinsing water, so that the purified water resources can be returned to the storage tank through the return pipe for recycling. This reduces water waste, lowers production water costs, and avoids cross-contamination of the next batch of materials caused by residual raw materials. It fundamentally ensures the consistency of the product quality of food compound seasonings and reduces production losses caused by raw material contamination.

[0022] 3. In this invention, the drying component and the rinsing component work together. After rinsing, the humidity sensor monitors the humidity in the feeding channel in real time and transmits the electrical signal to the control panel, automatically starting the fan and the semiconductor heating element. The semiconductor heating element can quickly heat the air inside the device base. The fan sends the hot air into the device base through the air supply pipe. The heated air is then precisely delivered to the inside of the feeding channel through the exhaust pipe, forming a directional airflow circulation. This can remove residual moisture from the inner wall of the channel in a short time, achieving rapid drying of the feeding channel. This design not only avoids problems such as raw material adhesion and equipment component corrosion caused by a humid environment in the channel, extending the service life of the equipment, but also ensures the smooth progress of the next feeding process, avoiding raw material clumping and blockage caused by dampness in the channel, further improving the continuity and stability of the production process.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Example 1

[0032] Reference Figure 1-3 An automatic feeding system for processing compound food seasonings includes a base 1 with rollers, a feeding bin 4, a feeding component and a rinsing component. A rear support 2 and a front support 3 are fixedly installed on the upper end of the base 1. The feeding bin 4 is fixedly installed on the upper end of the rear support 2, and a control panel 5 is fixedly installed on the side wall of the feeding bin 4.

[0033] The feeding assembly consists of a feeding channel 6, a feeding auger plate 29, a drive mechanism, and a discharge port 15. It is used to feed raw materials during seasoning processing. The feeding channel is fixedly installed above the base 1, with its middle section fixedly connected to the front support 3 and its rear section located below the discharge bin 4 and connected to the opening below the discharge bin 4. The feeding auger plate 29 is rotatably connected inside the feeding channel 6, and the discharge port 15 is located below the front end of the feeding channel 6 and connected to it.

[0034] The drive mechanism includes a drive motor 27 and a pair of drive wheels 28. The drive motor 27 is fixedly mounted on the base 1 by a fixing plate. One drive wheel 28 is coaxially fixedly connected to the output shaft of the drive motor 27. The other drive wheel 28 is rotatably mounted at the bottom of the feeding channel 6 and coaxially fixedly connected to the feeding auger plate 29. The pair of drive wheels 28 are connected by a transmission belt.

[0035] The rinsing assembly consists of an infrared sensor 22, a water pump 8, a water tank 9, an inlet pipe 11, an outlet pipe 12, and a rinsing nozzle 13. It is used to rinse the feeding channel 6 after feeding to ensure that there is no residue for the next feeding. A horizontal plate 7 is fixedly installed on the upper end of the front bracket 3. The water pump 8 is fixedly installed on the upper end of the horizontal plate 7. The infrared sensor 22 is installed inside the feeding bin 4 to monitor the raw material in the feeding bin 4. The water tank 9 is fixedly installed inside the base 1. The inlet pipe 11 is connected between the water pump 8 and the water tank 9. The outlet pipe 12 is connected between the water pump 8 and the rinsing nozzle 13. The rinsing nozzle 13 is fixedly installed on the top of the feeding channel 6 and the water outlet extends into its interior. A device base 16 is fixedly installed below the front end of the feeding channel. A control mechanism for controlling the opening and closing of the feeding port 15 is installed on the device base 16. A return mechanism for recycling the rinsing water is installed on the water tank 9.

[0036] The control mechanism consists of a sealing plate 20, an electric push rod 17, a sliding block 18, and a connecting rod 19. The sealing plate 20 is slidably connected to the lower end of the discharge port 15. The electric push rod 17 is fixedly installed on the side wall of the device base 16, and a groove 17 is provided on the side wall of the device base 16. The sliding block 18 is slidably connected in the groove 17 and fixedly connected to the telescopic end of the electric push rod 17. One end of the connecting rod 19 is rotatably connected to the lower end of the sliding block 18, and the other end is rotatably connected to the lower end of the sealing plate 20.

[0037] The reflux mechanism includes a reflux pipe 14 and a filter screen 10. The reflux pipe 14 is connected between the lower end of the feeding channel 6 and the lower end of the water storage tank 9. The filter screen 10 is fixedly installed on the inner wall of the water storage tank 9 and located above the reflux pipe 14. A first solenoid valve 21 is installed at the connection between the reflux pipe 14 and the feeding channel 6. The first solenoid valve 21 is electrically connected to the control panel 5 and is controlled by an infrared sensor 22.

[0038] The inner wall of the feeding channel 6 is coated with an anti-stick coating made of polytetrafluoroethylene, and the coating thickness is uniformly covering all areas of the inner wall of the feeding channel. The top of the unloading bin 4 is equipped with an openable and closable sealing cover. The sealing cover is rotatably connected to the top edge of the unloading bin 4 via a hinge. The inner edge of the sealing cover is equipped with an elastic sealing gasket. When the sealing cover is closed, it fits tightly against the top opening of the unloading bin 4.

[0039] In this embodiment, when the food compound seasoning is being processed, the seasoning raw materials to be processed are first added into the feeding hopper 4. The equipment is started through the control panel 5, and the infrared sensor 22 monitors the amount of raw materials in the feeding hopper 4 in real time and sends a feedback signal to the control panel 5.

[0040] Control panel 5 triggers the operation of the drive mechanism. After the drive motor 27 starts, it drives the transmission wheel 28, which is fixed coaxially with its output shaft, to rotate. The transmission wheel 28 drives another set of transmission wheels 28, which are fixed coaxially with the feeding auger plate 29, to rotate synchronously through the transmission belt, thereby driving the feeding auger plate 29 in the feeding channel 6 to rotate continuously.

[0041] The raw materials in the feeding hopper 4 fall into the feeding channel 6 through the lower opening. Under the spiral pushing action of the feeding auger plate 29, they move towards the front end along the feeding channel 6 and are finally discharged from the feeding port 15, completing the raw material feeding.

[0042] Meanwhile, the control panel 5 can adjust the opening and closing state and degree of opening and closing of the discharge port 15 by controlling the extension and retraction of the electric push rod 17. When the electric push rod 17 extends and retracts, it drives the sliding block 18 to slide along the slide groove 17 on the side wall of the device base 16. The sliding block 18 pulls the sealing plate 20 to slide at the lower end of the discharge port 15 through the connecting rod 19, so as to achieve precise control of the discharge port 15 and adapt to different feeding requirements.

[0043] When the infrared sensor 22 detects that the raw materials in the feeding hopper 4 have been completely conveyed, it sends an electrical signal to the control panel 5. The control panel 5 then activates the flushing assembly and controls the first solenoid valve 21 to open. During operation, the water pump 8 draws clean water from the storage tank 9 through the inlet pipe 11 and delivers it through the outlet pipe 12 to the flushing nozzle 13 fixedly installed at the top of the feeding channel 6. The flushing nozzle 13 sprays water in all directions onto the inner wall of the channel, rinsing away any remaining raw materials. The flushing water carrying impurities flows along the inner wall of the feeding channel 6 to the lower end and returns to the storage tank 9 through the return pipe 14. When it flows through the filter screen 10 inside the storage tank 9, the raw material impurities are filtered and retained. The purified water is stored in the storage tank 9, achieving the recycling of the flushing water for reuse in the next flushing process.

[0044] It should be noted that during the feeding process, the first solenoid valve 21 is in a closed state throughout, which effectively prevents the raw material from falling from the return pipe 1 and causing blockage of the return pipe 14.

[0045] Example 2

[0046] Reference Figure 4 An automatic feeding system for processing compound food seasonings, differing from Embodiment 1 in that it further includes a drying component. The drying component consists of a fan 8 and an air duct, used for rapidly drying the rinsed feeding channel 6. The fan 8 is fixedly installed on the upper end of a horizontal plate 7, and the air duct connects the fan 8 to the feeding channel 6. A humidity sensor 31 is fixedly installed at the bottom of the feeding channel 6. The fan 23 is electrically connected to the control panel 5 and controlled by the electrical signal from the humidity sensor 31.

[0047] In this embodiment, the drying component works in conjunction with the feeding component and the rinsing component to achieve fully automated connection of the feeding, rinsing, and drying process. After the rinsing component completes the rinsing process of the feeding channel 6, the humidity sensor 31 at the bottom of the feeding channel 6 monitors the humidity data in the channel in real time and feeds the signal back to the control panel 5. When the humidity value is higher than the preset standard, the control panel 5 automatically triggers the drying component to start. After the fan 23 runs, it draws in outside air and delivers airflow into the feeding channel through the air duct, which can effectively dry the feeding channel 6 after rinsing, so that it can quickly restore its dry and clean state, ensuring the smooth feeding of the next batch of raw materials and the purity of the raw materials.

[0048] Example 3

[0049] Reference Figure 5-6 An automatic feeding system for processing compound food seasonings differs from embodiments 1 and 2 in that the air duct includes two parts: an air supply pipe 24 and an exhaust pipe 25. The device base 16 is a hollow cylinder with a semiconductor heating element 30 fixedly installed inside. The air supply pipe 24 is connected between the fan 23 and one end of the device base 16, and the exhaust pipe 25 is connected between the other end of the device base 16 and the lower end of the feeding channel 6.

[0050] A second solenoid valve 26 is installed at the connection between the exhaust pipe 25 and the feeding channel 6. The second solenoid valve 26 and the semiconductor heating element 30 are both electrically connected to the control panel 5 and controlled by the electrical signal of the humidity sensor 31.

[0051] In this embodiment, after the rinsing assembly completes the rinsing operation of the feeding channel 6, the humidity sensor 31 at the bottom of the feeding channel 6 continuously monitors the humidity data of the inner wall of the channel and the internal environment, and transmits the monitoring signal to the control panel 5 in real time. When the control panel 5 determines that the humidity data is higher than the preset drying threshold, it immediately triggers the drying assembly to start, and at the same time sends an opening signal to the second solenoid valve 26 to keep the exhaust pipe 25 connected to the feeding channel 6.

[0052] After the fan 23 starts, it continuously draws in ambient air and directs it through the air pipe 24 to the hollow cylindrical device base 16. At this time, the semiconductor heating element 30, which is electrically connected to the control panel 5, is simultaneously energized and heats up, using its efficient heat conversion performance to rapidly heat the air entering the device base 16, converting the ambient air into hot air suitable for drying. The heated air flows along the internal cavity of the device base 16 to the exhaust pipe 25 at the other end, and is precisely delivered to the lower end of the feeding channel 6 through the exhaust pipe 25. It then forms a uniform hot airflow circulation along the inner wall of the channel, fully covering the internal space of the feeding channel 6, quickly removing residual moisture after rinsing, and preventing the formation of damp dead corners in the channel.

[0053] During the drying process, the humidity sensor 31 continuously collects humidity data within the channel and feeds it back to the control panel 5, forming a closed-loop control. When the humidity data is detected to drop to a preset threshold, the control panel 5 simultaneously sends a shutdown signal to the fan 23, the semiconductor heating element 30, and the second solenoid valve 26. The fan stops blowing air, the semiconductor heating element stops heating, and the second solenoid valve 26 closes to prevent outside air from entering the feeding channel 6, thus precisely ending the drying process. This design, through the directional heating of the semiconductor heating element and the precise on / off control of the second solenoid valve, ensures drying efficiency while avoiding energy waste. It also effectively prevents external impurities or moisture from flowing back into the channel through the exhaust pipe, further ensuring the cleanliness of the feeding channel and providing a more reliable guarantee for the purity and smoothness of the next batch of raw materials.

[0054] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
