Description

Technical Field

[0001] This utility model belongs to the field of food processing technology, specifically relating to a device for quantitative addition of seasonings in meat processing. It is particularly suitable for the precise delivery and proportioning of solid and liquid seasonings in meat marinating, mixing and other processes. It can realize the automated quantitative addition and mixing of various seasonings, thereby improving the standardization and production efficiency of meat processing. Background Technology

[0002] In the meat processing industry, the precise addition of seasonings is a crucial process affecting product flavor stability and production efficiency. Currently, the most widely used seasoning addition methods in the industry mainly include manual addition and automated mechanical addition.

[0003] Manual addition relies on operators using weighing tools (such as platform scales and measuring cups) to obtain a fixed amount of seasoning before manually adding it to the processing equipment. While this method has low equipment costs, it has significant limitations: First, the accuracy of addition is greatly affected by human experience, and the amount of seasoning used in different batches of products can easily deviate by more than ±5%, resulting in poor consistency in product flavor. Second, for large-scale production, manual addition is inefficient, with single-shift capacity typically limited to below 500 kg / h, making it difficult to meet the cycle time requirements of modern production lines. Third, direct contact between humans and seasonings increases the risk of microbial contamination, failing to meet the hygiene control requirements for the processing process in GB14881-2013 "General Hygiene Standard for Food Production".

[0004] To address the shortcomings of manual seasoning, automated mechanical seasoning devices have emerged in the prior art, such as Chinese Patent No. CN217147858U, "A Quantitative Seasoning Device for Meat Product Processing." This device, through the installation of a support frame, positioning frame, and extrusion rollers, adjusts the distance between seasoning bins one and two by controlling the movement of a threaded rod and a positioning plate, thereby controlling the feed rate. The extrusion rollers also control the closing of the seasoning feed by pressing against the extrusion tube. However, such devices still have the following problems in practical applications:

[0005] The device mainly controls the feeding by adjusting the spacing between the hoppers and the extrusion rollers. It is greatly affected by the characteristics of the seasonings themselves, such as particle size (powdered seasonings are prone to agglomeration, and granular seasonings are uneven in size) and humidity (some seasonings are prone to clumping when the moisture content is >8%), making it difficult to meet the stringent requirements of high-end meat products (such as low-temperature ham and fermented sausages) for seasoning ratios.

[0006] The connection design between the discharge end of the conveying mechanism and the mixing chamber is relatively simple and lacks an effective transition guide structure, which makes it easy for the seasoning to spill during the falling process. This not only wastes raw materials, but also requires frequent cleaning of the surrounding environment of the equipment, increasing production costs and the difficulty of hygiene management.

[0007] Most existing similar devices are designed for single-form seasonings, such as being only suitable for solid powders or only suitable for liquid seasonings. However, in actual meat processing, it is often necessary to add both solid (such as salt and pepper) and liquid (such as soy sauce and flavoring) seasonings at the same time. This requires two separate sets of equipment, which not only increases the equipment footprint but also significantly increases the procurement cost.

[0008] Therefore, in view of the problems existing in the current technology, such as limited quantitative accuracy, unreasonable structural connection, poor compatibility with multiple media and low degree of automation integration, there is an urgent need to develop a quantitative dosing device that can achieve high precision, low loss, compatibility with multiple forms of seasonings and easy maintenance, so as to meet the actual needs of the meat processing industry. Summary of the Invention

[0009] To solve the above problems, this utility model provides a quantitative seasoning dosing device for meat product processing, the specific technical solution of which is as follows:

[0010] A meat processing seasoning quantitative dosing device includes a frame, a hopper, a quantitative conveying mechanism, a discharge hopper, a mixing device, and a control system. The hopper is mounted on the frame. The inlet of the quantitative conveying mechanism is fixedly connected to the outlet of the hopper via a flange and is internally connected. The discharge hopper has a funnel-shaped structure, with its upper end fixedly connected to the outlet of the quantitative conveying mechanism via a flange and internally connected, and its lower outlet aligned with the cavity inlet of the mixing device. The mixing device includes a collecting trough and stirring blades disposed within the collecting trough, the collecting trough forming the cavity for receiving the seasoning conveyed by the discharge hopper. The stirring blades are equipped with a stirring shaft at their center. The control system includes a conveying motor, a mixing motor, a PLC control box, and a motor driver. The output shaft of the conveying motor is fixedly connected to the drive shaft of the quantitative conveying mechanism via a coupling. The output shaft of the mixing motor is fixedly connected to the stirring shaft via a coupling. The conveying motor and the mixing motor are electrically connected to the controller in the PLC control box via motor drivers. The controller outputs pulse signals to the motor driver through a preset program to control the start / stop, speed, and running time of the conveying motor and the mixing motor, thereby adjusting the amount of seasoning conveyed and the stirring rate.

[0011] Furthermore, there are multiple hoppers for storing different types of seasonings; the number of quantitative conveying mechanisms and discharge hoppers is matched with the number of hoppers, and each quantitative conveying mechanism independently corresponds to one hopper and one discharge hopper; the hoppers, quantitative conveying mechanisms and discharge hoppers constitute independent feeding components, and the lower outlet of the discharge hopper of each component is aligned with the cavity inlet of the collecting trough.

[0012] Furthermore, the quantitative conveying mechanism is a rotary valve feeder, including a valve body, a rotor, and a drive shaft. The rotor is rotatably mounted inside the valve body, forming multiple evenly distributed quantitative chambers between the rotor and the inner wall of the valve body. The upper end of the valve body is provided with an inlet communicating with the outlet of the hopper, and the lower end is provided with an outlet communicating with the upper end of the discharge hopper. One end of the drive shaft is fixedly connected to the center of the rotor, and the other end extends out of the valve body and is connected to the output shaft of the conveying motor through a coupling. The rotation of the rotor causes the quantitative chambers to alternately complete the feeding and discharging, thereby realizing the quantitative conveying of the seasoning.

[0013] Furthermore, the conveying motor is a servo motor with an encoder. The encoder is electrically connected to the controller in the PLC control box and is used to provide real-time feedback on the rotation angle and speed of the rotor. The controller receives the feedback signal from the encoder and, in combination with the preset quantitative chamber volume parameters, dynamically adjusts the output of the servo motor through the motor driver to achieve closed-loop control of the seasoning conveying volume.

[0014] Preferably, the inner wall of the discharge hopper is a smooth curved surface, and the diameter of the lower outlet is 1 / 3 to 1 / 2 of the diameter of the upper inlet, so as to reduce seasoning residue and guide the seasoning to fall accurately into the cavity of the collecting trough.

[0015] Preferably, the hopper is mounted on the frame via a detachable connector, which is either a snap-fit ​​assembly or a bolt assembly with a handle, to facilitate quick disassembly, cleaning, and replacement.

[0016] Furthermore, the top of the hopper is provided with a feeding port, and the feeding port is provided with a flip-up hopper cover. One side of the hopper cover is connected to the edge of the feeding port by a hinge, and the other side is provided with a latch. A silicone sealing ring is provided on the contact surface between the hopper cover and the feeding port.

[0017] Furthermore, the silo is equipped with a capacitive level gauge, whose detection probe extends vertically into the silo and is 1 / 5 to 1 / 4 of the total height of the silo from the bottom of the silo; the signal output terminal of the capacitive level gauge is electrically connected to the controller in the PLC control box through a signal line. When the level gauge detects that the remaining material level is lower than the preset threshold, the controller drives the alarm device to issue an audible and visual alarm signal.

[0018] Furthermore, it also includes a liquid seasoning dosing unit, which includes a storage tank, a liquid metering pump, and a three-way solenoid valve. The inlet of the liquid metering pump is connected to the storage tank through a pipe, and the outlet is connected to the inlet of the three-way solenoid valve through a pipe. The two outlets of the three-way solenoid valve are respectively connected to the cavity of the collection tank and the meat processing equipment through pipes. The liquid metering pump and the three-way solenoid valve are both electrically connected to the controller in the PLC control box through signal lines, and the controller synchronously adjusts the liquid flow rate and delivery path.

[0019] Preferably, the inner wall surfaces of the hopper, the valve body of the quantitative conveying mechanism, and the discharge hopper are all made of 304 stainless steel, and the inner walls are mirror-polished with a surface roughness Ra≤0.8μm.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] This invention significantly reduces the error in adding seasonings by using the quantitative chamber of the rotary valve feeder and the closed-loop control of the servo motor, thus meeting the requirements for high-precision proportioning. It can process both solid and liquid seasonings simultaneously, eliminating the need for multiple sets of equipment, effectively saving space and reducing procurement costs. It also features high quantitative accuracy, low seasoning loss, and strong adaptability. Furthermore, the PLC control system can be linked with the production line to automatically adjust the addition amount, significantly improving production efficiency and the level of processing standardization.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1 to 4 As shown, a meat processing seasoning quantitative dosing device consists of a frame 1, a hopper 2, a quantitative conveying mechanism 3, a discharge hopper 4, a mixing device 5, a control system, and a liquid seasoning dosing unit. The frame 1 is made of square steel welded together, serving as the installation foundation for the entire device, and its surface is treated with rust prevention to adapt to the food processing environment.

[0030] The hopper 2 is mounted on the frame 1 via a snap-fit ​​assembly for easy disassembly and cleaning. There are three hoppers 2, each used to store different solid seasonings such as salt, sugar, and pepper. Each hopper 2 has a feeding port 21 at the top, fitted with a flip-up cover 22. One side of the cover 22 is connected to the edge of the feeding port 21 via a hinge, while the other side has a locking mechanism. A silicone sealing ring 24 is embedded in the contact surface between the cover 22 and the feeding port 21 to effectively prevent the seasonings from getting damp or contaminating with impurities. Each hopper 2 also contains a capacitive level gauge 23. Its detection probe extends vertically into the hopper 2, reaching a height of 1 / 4 of the total height of the hopper from the bottom. When the detected seasoning level falls below a preset threshold, the capacitive level gauge 23 transmits a signal to the controller in the PLC control box via a signal line. The controller then activates an alarm device to issue an audible and visual alarm.

[0031] The feed end of the quantitative conveying mechanism 3 is fixedly connected to the discharge port of the hopper 2 via a flange and is internally interconnected. The number of these mechanisms is the same as that of the hopper 2, which is 3. Each quantitative conveying mechanism 3 corresponds independently to one hopper 2. The quantitative conveying mechanism 3 adopts a rotary valve feeder, which includes a valve body, a rotor, and a drive shaft. The rotor is rotatably mounted in the valve body, forming 6 evenly distributed quantitative chambers between it and the inner wall of the valve body. The upper end of the valve body is provided with a feed inlet 32 ​​that communicates with the discharge port of the hopper 2, and the lower end is provided with a discharge port 33 that communicates with the discharge hopper 4. One end of the drive shaft is fixedly connected to the center of the rotor, and the other end extends out of the valve body and is connected to the output shaft of the conveying motor 31 via a coupling.

[0032] The discharge hopper 4 has a funnel-shaped structure, and there are three of them to match the quantitative conveying mechanism 3. The upper end of the hopper 4 is fixedly connected to the discharge port 33 of the quantitative conveying mechanism 3 through a flange and is internally connected. The lower outlet is aligned with the cavity inlet of the mixing device 5. The inner wall of the discharge hopper 4 is a smooth curved surface, and the diameter of the lower outlet is set to 1 / 2 of the diameter of the upper inlet to reduce seasoning residue and guide the seasoning to fall accurately into the collection trough.

[0033] The mixing device 5 includes a material collection trough and a stirring blade 6. The material collection trough forms a cavity for receiving seasonings, and the lower outlets of the three discharge hoppers 4 are all aligned with this cavity. The stirring blade 6 has a stirring shaft at its center, which is fixedly connected to the output shaft of the mixing motor 7 via a coupling. The mixing of various seasonings is achieved by rotating the stirring blade 6.

[0034] The control system consists of a conveyor motor 31, a mixing motor 7, a PLC control box, and a motor driver. The conveyor motor 31 is a servo motor with an encoder. Its output shaft is fixedly connected to the drive shaft of the quantitative conveying mechanism 3 via a coupling. The encoder is electrically connected to the controller in the PLC control box, providing real-time feedback on the rotor's rotation angle and speed. The controller receives the encoder's feedback signal and, combined with preset quantitative chamber volume parameters, dynamically adjusts the servo motor's output via the motor driver to achieve closed-loop control of the material conveying volume. The mixing motor 7 is electrically connected to the controller in the PLC control box via a motor driver. The controller outputs pulse signals through a preset program to control its start / stop, speed, and running time, thus adjusting the mixing rate.

[0035] The device also includes a liquid seasoning dosing unit, which consists of a storage tank, a liquid metering pump, and a three-way solenoid valve. The inlet of the liquid metering pump is connected to the storage tank through a pipe, and the outlet is connected to the inlet of the three-way solenoid valve through a pipe. The two outlets of the three-way solenoid valve are connected to the cavity of the collection tank and the meat processing equipment through pipes, respectively. Both the liquid metering pump and the three-way solenoid valve are electrically connected to the controller in the PLC control box through signal lines, and the controller synchronously adjusts the liquid flow rate and delivery path.

[0036] In this embodiment, the valve bodies of the hopper 2 and the quantitative conveying mechanism 3, as well as the inner wall surfaces of the discharge hopper 4 that come into contact with the seasonings, are all made of 304 stainless steel, and the inner walls are mirror-polished with a surface roughness Ra≤0.8μm, which meets the requirements of food hygiene.

[0037] During operation, the controller drives the conveyor motor 31 to rotate the rotor according to the preset program or production line signal. The quantitative chamber alternately completes the feeding and discharging to realize the quantitative conveying of solid seasonings. At the same time, the liquid seasoning dosing unit conveys liquid seasonings according to the set parameters. The two seasonings are mixed by the stirring blades 6 in the collection tank and then enter the next process. The whole process is automated and coordinated by the PLC control box.

[0038] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
