Description

Technical Field

[0001] This invention relates to the field of screening equipment technology, and in particular to a vibrating screening device and method for screening meat powder mixtures. Background Technology

[0002] In the processing of meat powder mixtures (such as sweet and sour pork tenderloin, crispy pork, etc.), the treated meat powder is first mixed, and then the powdered meat strips are manually dispersed to prevent sticking in subsequent processes (coating with batter). Currently, the process of dispersing the powdered meat strips involves first placing the meat powder mixture on a conveyor belt, then dispersing it manually, and finally conveying it to the subsequent batter coating process.

[0003] The existing dispersion method has the following disadvantages: (1) The efficiency of manual dispersion operation is low and the continuous operation is very labor-intensive; (2) The flour attached to the conveyor belt needs to be cleaned regularly to avoid the growth of microorganisms, but the cleaning is inconvenient, which affects the processing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a vibrating sieving device for meat powder mixtures, which improves the dispersion efficiency of meat strips containing powder and facilitates cleaning.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a vibrating sieving device for meat powder mixture, comprising a frame, a vibrating screen plate disposed on the frame, four elastic connecting components disposed between the frame and the vibrating screen plate, and a vibrating motor disposed at the bottom of the vibrating screen plate. The bottom plate of the vibrating screen plate is corrugated and inclined, and the bottom plate of the vibrating screen plate is provided with an array of anti-slip recesses to improve surface friction. A sliding frame for mounting the four elastic connecting components is slidably connected to the frame, and a driving mechanism for moving the multiple sliding frames is disposed between the frame and the four sliding frames. A rinsing pipe is disposed at the top of the higher end of the vibrating screen plate, and the rinsing pipe is provided with multiple water outlets connected to each recess of the bottom plate of the vibrating screen plate. One end of the frame is provided with a water inlet pipe located below the higher end of the vibrating screen plate, and the other end of the frame is provided with a water collection tank located below the lower end of the vibrating screen plate. A quick-connect fitting is provided between the water inlet pipe and the flushing pipe to connect them as the sliding frame moves toward the water inlet pipe. During the connection process of the quick-connect fitting, the lowest end of the vibrating screen plate moves above the water collection tank. The cleaning of the vibrating screening device includes the following operation steps: (S1) First, the sliding frame is moved by the drive mechanism so that the quick-connect fitting connects the water inlet pipe and the flushing pipe, so that the lowest end of the vibrating screen plate is located above the water collection tank; (S2) Water is supplied by the water inlet pipe, and water flows into multiple recesses of the vibrating screen plate from multiple outlets and flows downward to flush; (S3) The wastewater after cleaning flows into the water collection tank for collection.

[0006] By adopting the above technical solution, the meat powder mixture is first vibrated and screened. The bottom plate is corrugated, which allows the powdered meat strips to be dispersed in multiple channels. The anti-slip recesses on the bottom plate increase the friction coefficient of the powdered meat strips during movement, providing ample time for dispersion. When cleaning is required, the following steps are taken: (S1) The sliding frame is moved by the drive mechanism, so that the quick-connect connector connects the water inlet pipe and the rinsing pipe, so that the lowest end of the vibrating screen plate is above the water collection tank; (S2) Water is supplied through the water inlet pipe, and water flows into multiple recesses of the vibrating screen plate from multiple outlets and flows downward to rinse; (S3) The wastewater after cleaning flows into the water collection tank for collection. Ultimately, this method improves the dispersion efficiency of the powdered meat strips and facilitates cleaning.

[0007] A further provision of the present invention is that: a drain pipe with a valve is provided at one end of the water collection tank, and a scraping mechanism for scraping the settled flour toward one end of the drain pipe is movably provided at the bottom of the water collection tank. The scraping mechanism includes guide rods arranged on both sides of the water collection tank along the width direction of the vibrating screen plate, a scraper slidably connected between the two guide rods, a compression spring sleeved on the guide rods and driving the scraper to move away from the drain pipe, a guide sleeve provided at one end of the water collection tank at the drain pipe, and a cable passing through the guide sleeve and with both ends arranged between the scraper and the sliding frame. When the driving mechanism drives the sliding frame to move downward toward the water inlet pipe, the cable overcomes the elastic force of the compression spring and pulls the scraper downward toward one end of the drain pipe.

[0008] By adopting the above technical solution, during the process of collecting flushing wastewater in the water collection tank, flour will settle at the bottom of the water collection tank. At this time, when the drive mechanism drives the sliding frame to move downwards towards the water inlet pipe, the cable overcomes the elastic force of the compression spring and pulls the scraper downwards towards the end of the drain pipe. This can scrape down the flour that settled last time towards the end of the drain pipe. In addition, during the flushing process, the scraper separates the flour accumulated during the scraping process from the flushing wastewater that enters later, which can prevent the flour accumulated during the scraping process from being washed away. Furthermore, the movement of the scraper and the movement of the sliding frame are linked together to achieve the function of automatic scraping.

[0009] A further provision of the present invention is that a stroke amplification mechanism is provided between the sliding frame and the cable. The stroke amplification mechanism includes a rack on the sliding frame, a gear ring rotatably connected to the frame and meshing with the rack, a winding wheel on the gear ring, and a guide ring on the frame and close to the winding wheel. The cable is connected to the winding wheel, and as the sliding frame moves downward toward the water inlet pipe, the rack drives the gear ring to rotate, thereby driving the winding wheel to wind the cable.

[0010] By adopting the above technical solution, since the travel distance of the sliding frame and the travel distance of the scraper do not match, a travel amplification mechanism can be set up so that the travel distance of the sliding frame and the travel distance of the scraper can be matched by adjusting the winding radius of the winding wheel.

[0011] A further configuration of the present invention is as follows: a feeding hopper is provided at the higher end of the vibrating screen plate, a feeding port is provided at the top of the feeding hopper, and a plurality of discharge ports are provided at the bottom of the feeding hopper, each located above a recessed portion of the bottom plate of the vibrating screen plate; a discharge channel is provided between the feeding port and the plurality of discharge ports; the feeding hopper includes an outer shell and an inner shell inserted into the outer shell in a vertically downward direction; the feeding port, the discharge port and the discharge channel are all formed on the inner shell; and a lifting ring is provided at the upper end of the inner shell.

[0012] By adopting the above technical solution, and by setting up a feeding hopper with multiple discharge ports that are respectively aligned with each recess of the bottom plate of the vibrating screen plate, the meat powder mixture can be directly fed into the feeding hopper, and can be evenly dispersed to each recess of the bottom plate during vibration. At the same time, the feeding hopper includes an outer shell and an inner shell inserted downward into the outer shell. The inner shell can be easily cleaned after disassembly, and can be replaced for use during processing.

[0013] A further configuration of the present invention is as follows: the feed hopper is slidably connected to both sides of the vibrating screen plate, and a traction mechanism is provided between the feed hopper and the frame to move the feed hopper inclined upward along the vibrating screen plate. The feed hopper is provided with a screen hole plate assembly for covering or opening the discharge port. After the bottom plate of the vibrating screen plate is cleaned, the following operation is performed: flour is fed into the feed port, so that the flour falls into multiple discharge ports and is blocked by the screen hole plate assembly. At the same time as the vibration motor is started, the traction mechanism is gradually released, so that the feed slides down the vibrating screen plate inclinedly, so that the flour in the feed hopper is spread on the vibrating screen plate during vibration.

[0014] By adopting the above technical solution, when vibrating and screening the meat powder mixture, if the powdered meat strips are not locally coated with flour, they will stick to the bottom plate of the vibrating screen, thus affecting the vibration feeding. At this time, by using the sliding setting of the feed hopper, the setting of the traction mechanism, and the setting of the screen plate assembly to cover multiple discharge ports, the flour is fed from the feed port, so that the flour falls at multiple discharge ports and is blocked by the screen plate assembly. When the vibration motor is started, the traction mechanism is gradually released, so that the feed slides down the vibrating screen plate at an incline. This allows the flour in the feed hopper to be spread on the vibrating screen plate during vibration, thus ensuring that the powdered meat strips do not stick together.

[0015] A further configuration of the present invention is as follows: the lower surface of the outer casing is arc-shaped, and arc-shaped tracks are provided on both sides of the two ends of the outer casing. The screen plate assembly includes an arc-shaped screen plate that is slidably connected to the arc-shaped tracks and abuts against the lower surface of the outer casing, and two locking knob bolts that are respectively threaded to the lower ends of the two arc-shaped tracks near the vibrating screen plate. Two limiting holes for the locking knob bolts to be inserted are respectively provided on the end face of the arc-shaped screen plate. When the locking knob bolt is inserted into one of the limiting holes, the arc-shaped screen plate covers multiple discharge ports. When the locking knob bolt is inserted into the other limiting hole, the arc-shaped screen plate moves towards the lower end near the vibrating screen plate to the limit state and does not interfere with the discharge port.

[0016] By adopting the above technical solution, when the locking knob bolt is embedded in one of the limiting holes, the arc-shaped screen plate covers multiple discharge ports. When the locking knob bolt is embedded in another limiting hole, the arc-shaped screen plate moves towards the lower end of the vibrating screen plate to the limit state without interfering with the discharge port, thereby achieving the functional purpose of the screen hole plate assembly covering or opening the discharge port.

[0017] A further provision of the present invention is as follows: a drying mechanism is provided between the frame and the outer casing. The drying mechanism includes an air outlet pipe disposed on the side of the outer casing near the lower end of the vibrating screen plate, a fan disposed on the frame, and a flexible hose disposed between the fan and the air outlet pipe. The bottom of the air outlet pipe is provided with multiple air outlet holes. The side of the arc-shaped screen plate near the higher end of the vibrating screen plate is provided with a notch. When the arc-shaped screen plate moves towards the lower end of the vibrating screen plate to its limit state, the notch moves to the side of the outer casing and is not covered by the lower surface of the outer casing, and the upper side of the arc-shaped screen plate abuts against the air outlet pipe. Air flows along the fan, the flexible hose, the multiple air outlet holes of the air outlet pipe, the space between the outer casing and the arc-shaped screen plate, and the notch. Covering plates are provided on both sides of the air outlet pipe to cover the cavity between the sides of the arc-shaped screen plate and the outer casing.

[0018] By adopting the above technical solution, after rinsing the bottom of the vibrating screen plate, the residual moisture on the bottom plate surface can be dried by the drying mechanism. At this time, the upper side of the arc-shaped screen plate abuts against the air outlet pipe, and the notch moves to the side of the outer shell and is not covered by the lower surface of the outer shell. This allows the arc-shaped screen plate to move and guide the airflow, causing the air to flow along the fan, hose, multiple air outlets of the air outlet pipe, the space between the outer shell and the arc-shaped screen plate, and the notch, and blow towards the bottom plate of the vibrating screen plate for drying. The cover plate allows the outer shell, the arc-shaped screen plate, and the cover plate to form an annular cavity, improving the airflow guiding effect.

[0019] The purpose of this invention is to provide a vibratory sieving method for meat powder mixtures, which improves the dispersion efficiency of meat strips containing powder and facilitates cleaning.

[0020] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a vibratory sieving method for a meat powder mixture, comprising the following steps: (S1) Powder spreading process: firstly, the screen plate assembly covers multiple discharge ports, and flour is fed into the feed hopper, so that the flour falls at multiple discharge ports and is blocked by the screen plate assembly. While starting the vibration motor, the traction mechanism is gradually released so that the feed hopper slides down along the vibratory screen plate, so that the flour in the feed hopper is spread on the vibratory screen plate during vibration. After spreading, the arc-shaped screen plate of the screen plate assembly moves downward close to the lower end of the vibratory screen plate to the limit state and does not interfere with the discharge port; (S2) Vibration Dynamic screening process: The meat powder mixture is fed into the feed inlet of the feed hopper. During the vibration of the vibrating motor, the powder-containing meat strips fall into each recess of the bottom plate of the vibrating screen plate through multiple feeding channels and discharge outlets. The powder-containing meat strips gradually disperse under the vibration of the vibrating screen plate. (S3) Cleaning process: First, the sliding frame is moved by the drive mechanism, so that the quick-connect connector connects the water inlet pipe and the rinsing pipe, so that the lowest end of the vibrating screen plate is above the water collection tank. Water is supplied by the water inlet pipe, and water flows into multiple recesses of the vibrating screen plate from multiple outlets and flows downward to rinse. The wastewater after cleaning flows into the water collection tank for collection. The inner shell of the feed hopper is disassembled and cleaned.

[0021] A further provision of the present invention includes step (S4) of blowing clean the arc-shaped sieve plate: during the cleaning process, the fan is started, so that air flows along the multiple air outlets of the fan, hose, air outlet pipe, the space between the outer shell and the arc-shaped sieve plate, and the gaps, blowing off the clean flour remaining on the arc-shaped sieve plate, so that the flour adheres to the flowing water of the cleaning process.

[0022] The invention is further configured to include a step (S5) drying process: after steps (S3) and (S4) are completed, the traction mechanism and the fan are started, the traction mechanism is gradually released so that the feed hopper slides down along the vibrating screen plate at an incline, and air flows along the multiple air outlets of the fan, hose, air outlet pipe, the space between the outer shell and the arc-shaped screen plate, and the gaps, so as to blow off and dry the residual water on the vibrating screen plate.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1: A vibrating sieving device for meat meal mixture, such as Figure 1 As shown, it includes a frame 1, a vibrating screen plate 2 mounted on the frame 1, four elastic connecting components 3 mounted between the frame 1 and the vibrating screen plate 2, and a vibrating motor 4 mounted at the bottom of the vibrating screen plate 2.

[0027] like Figure 1 and Figure 2 As shown, the bottom plate of the vibrating screen plate 2 is corrugated and inclined. The bottom plate of the vibrating screen plate 2 is provided with an array of anti-slip recesses to improve surface friction. During the processing, the bottom plate is first stamped to form the anti-slip recesses, and then folded into a corrugated shape by a folding machine.

[0028] like Figure 1 and Figure 2As shown, a sliding frame 5 for mounting four elastic connecting components 3 is slidably connected to the frame 1. A drive mechanism 6 for moving multiple sliding frames 5 is provided between the frame 1 and the four sliding frames 5. The drive mechanism 6 is a cylinder, hydraulic cylinder, or electric push rod structure provided between the frame 1 and the sliding frames 5. A flushing pipe 7 is provided at the top of the higher end of the vibrating screen plate 2. The flushing pipe 7 is provided with multiple water outlets (not labeled) connected to each recess of the bottom plate of the vibrating screen plate 2. A water inlet pipe 8 is provided at one end of the frame 1 below the higher end of the vibrating screen plate 2. A water collection tank 9 is provided at the other end of the frame 1 below the lower end of the vibrating screen plate 2. A quick-connect connector 10 is provided between the water inlet pipe 8 and the flushing pipe 7 to connect during the movement of the sliding frames 5 toward the water inlet pipe 8. During the connection process of the quick-connect connector 10, the lowest end of the vibrating screen plate 2 moves above the water collection tank 9.

[0029] Implementation Results: Firstly, the meat powder mixture is vibrated and screened using a vibrating sieve. The corrugated bottom plate allows for the vibration dispersion of powdered meat strips within multiple channels. The anti-slip recesses on the bottom plate increase the friction coefficient of the powdered meat strips during movement, providing ample time for vibration dispersion. Simultaneously, when cleaning is required, the following steps are taken: (S1) The drive mechanism 6 moves the sliding frame 5, connecting the quick-connect fitting 10 to the water inlet pipe 8 and the rinsing pipe 7, ensuring the lowest point of the vibrating sieve plate 2 is above the water collection tank 9; (S2) Water is supplied through the water inlet pipe 8, flowing from multiple outlets into multiple recesses of the vibrating sieve plate 2 and rinsing downwards; (S3) The wastewater after cleaning flows into the water collection tank 9 for collection. Ultimately, this method improves the dispersion efficiency of powdered meat strips and facilitates cleaning.

[0030] Example 2: A vibrating sieving device for a meat meal mixture, such as Figure 1 , Figures 3 to 5As shown, the difference from Embodiment 1 is that: a drain pipe 9-1 with a valve is provided at one end of the water collection tank 9, and a scraping mechanism 9-2 for scraping the settled flour toward one end of the drain pipe 9-1 is movably provided at the bottom of the water collection tank 9. The scraping mechanism 9-2 includes guide rods 9-2-1 arranged on both sides of the water collection tank 9 along the width direction of the vibrating screen plate 2, a scraper 9-2-2 slidably connected between the two guide rods 9-2-1, and a scraper 9-2-2 sleeved on the guide rods 9-2-1 and driving the scraper 9-2-2 toward the water collection tank 9-1. The compression spring 9-2-3 moves away from the drain pipe 9-1, the guide sleeve 9-2-4 is set at one end of the water collection tank 9 located at the drain pipe 9-1, and the cable 9-2-5 passes through the guide sleeve 9-2-4 and is set at both ends between the scraper 9-2-2 and the sliding frame 5. When the drive mechanism 6 drives the sliding frame 5 to move downward toward the water inlet pipe 8, the cable 9-2-5 overcomes the elastic force of the compression spring 9-2-3 and pulls the scraper 9-2-2 downward toward the end of the drain pipe 9-1. A stroke amplification mechanism 15 is provided between the sliding frame 5 and the cable 9-2-5. The stroke amplification mechanism 15 includes a rack 15-1 on the sliding frame 5, a gear ring 15-2 rotatably connected to the frame 1 and meshing with the rack 15-1, a winding wheel 15-3 on the gear ring 15-2, and a guide ring 15-4 on the frame 1 and close to the winding wheel 15-3. The cable 9-2-5 is connected to the winding wheel 15-3. When the sliding frame 5 moves downward toward the water inlet pipe 8, the rack 15-1 drives the gear ring 15-2 to rotate, thereby driving the winding wheel 15-3 to wind the cable 9-2-5.

[0031] like Figure 3 , Figures 6 to 7 As shown, a feeding hopper 11 is provided at the higher end of the vibrating screen plate 2. The top of the feeding hopper 11 is provided with a feeding port 11-2-1, and the bottom of the feeding hopper 11 is provided with multiple discharge ports 11-2-2 located above each recess of the bottom plate of the vibrating screen plate 2. A discharge channel 11-2-3 is provided between the feeding port 11-2-1 and the multiple discharge ports 11-2-2. The feeding hopper 11 includes an outer shell 11-1 and an inner shell 11-2 inserted into the outer shell 11-1 in a vertically downward direction. The feeding port 11-2-1, the discharge port 11-2-2 and the discharge channel 11-2-3 are all formed on the inner shell 11-2. A lifting ring (not marked in the figure) is provided at the upper end of the inner shell 11-2.

[0032] like Figure 3 , Figure 6 and Figure 7As shown, the feed hopper 11 is slidably connected to both sides of the vibrating screen plate 2. A traction mechanism 12 is provided between the feed hopper 11 and the frame 1 to move the feed hopper 11 inclined upward along the vibrating screen plate 2. The traction mechanism 12 includes a winch 12-1 mounted on the frame 1 and a steel cable 12-2 mounted between the winch 12-1 and the feed hopper 11. The feed hopper 11 is provided with a screen plate assembly 13 for covering or opening the discharge port 11-2-2. After the bottom plate of the vibrating screen plate 2 is cleaned, the operation is performed: flour is fed into the feed port 11-2-1, so that the flour falls into multiple discharge ports 11-2-2 and is blocked by the screen plate assembly 13. At the same time as the vibration motor 4 is started, the traction mechanism 12 is gradually released, so that the feed slides down the vibrating screen plate 2 inclined, so that the flour in the feed hopper 11 is spread on the vibrating screen plate 2 during vibration.

[0033] like Figure 6 and Figure 7 As shown, the lower surface of the outer casing 11-1 is arc-shaped, and arc-shaped tracks 11-3 are provided on both ends of the outer casing 11-1. The screen plate assembly 13 includes an arc-shaped screen plate 13-1 that is slidably connected to the arc-shaped tracks 11-3 and abuts against the lower surface of the outer casing 11-1, and two locking knob bolts 13-2 that are respectively threaded to the lower ends of the two arc-shaped tracks 11-3 near the vibrating screen plate 2. Two limiting points for the locking knob bolts 13-2 to be inserted are respectively provided on the end face of the arc-shaped screen plate 13-1. Position hole 13-1-1 (only one is shown in the figure, the other limiting hole 13-1-1 corresponds to the locking knob bolt 13-2). When the locking knob bolt 13-2 is embedded in one of the limiting holes 13-1-1, the arc-shaped screen plate 13-1 covers multiple discharge ports 11-2-2. When the locking knob bolt 13-2 is embedded in the other limiting hole 13-1-1, the arc-shaped screen plate 13-1 moves towards the lower end of the vibrating screen plate 2 to the limit state and does not interfere with the discharge port 11-2-2.

[0034] like Figure 3 , Figure 6 and Figure 7As shown, a drying mechanism 14 is provided between the frame 1 and the outer casing 11-1. The drying mechanism 14 includes an air outlet pipe 14-1 located on the side of the outer casing 11-1 near the lower end of the vibrating screen plate 2, a fan 14-2 mounted on the frame 1, and a flexible hose 14-3 located between the fan 14-2 and the air outlet pipe 14-1. The bottom of the air outlet pipe 14-1 has multiple air outlet holes (not shown in the figure). The arc-shaped screen plate 13-1 has a notch 13 on the side near the higher end of the vibrating screen plate 2. -1-2, when the arc-shaped screen plate 13-1 moves towards its lower end near the vibrating screen plate 2 to its limit state, the notch 13-1-2 moves to the side of the outer casing 11-1 and is not covered by the lower surface of the outer casing 11-1, and the upper side of the arc-shaped screen plate 13-1 abuts against the air outlet pipe 14-1; air flows along the fan 14-2, the hose 14-3, the multiple air outlet holes of the air outlet pipe 14-1, the space between the outer casing 11-1 and the arc-shaped screen plate 13-1, and the notch 13-1-2. Covering plates 14-1-1 are provided on both sides of the air outlet pipe 14-1 to cover the cavity between the sides of the arc-shaped screen plate 13-1 and the outer casing 11-1.

[0035] Implementation Effect: During the collection of rinsing wastewater in the water collection tank 9, flour sediment will accumulate at the bottom of the tank. When the drive mechanism 6 moves the sliding frame 5 downwards towards the inlet pipe 8, the cable 9-2-5 overcomes the elasticity of the compression spring 9-2-3 and pulls the scraper 9-2-2 downwards towards the drain pipe 9-1. This scrapes off the previously settled flour near the drain pipe 9-1. During rinsing, the scraper 9-2-2 separates the accumulated flour from the subsequent rinsing wastewater, preventing the flour from being dispersed. Furthermore, the movement of the scraper 9-2-2 and the sliding frame 5 work together to achieve automatic scraping. Because the travel distance of the sliding frame 5 and the scraper 9-2-2 do not match, a travel amplification mechanism 15 is used. This allows adjustment of the winding radius of the winding wheel 15-3 to match the travel distance of the sliding frame 5 and the scraper 9-2-2.

[0036] By setting up a feeding hopper 11, and having multiple discharge ports 11-2-2 respectively aligned with each recess of the bottom plate of the vibrating screen plate 2, the meat powder mixture can be directly fed into the feeding hopper 11, and can be evenly dispersed to each recess of the bottom plate during vibration. At the same time, the feeding hopper 11 includes an outer shell 11-1 and an inner shell 11-2 inserted downward into the outer shell 11-1. The inner shell 11-2 can be easily cleaned after disassembly, and can be replaced with a cleaned inner shell 11-2 during processing.

[0037] When vibrating and screening the meat powder mixture, if the powdered meat strips are not partially covered with flour, they may stick to the bottom plate of the vibrating screen plate 2, thus affecting the feeding. In this case, by sliding the feed hopper 11, setting the traction mechanism 12, and setting the screen plate assembly 13 to cover multiple discharge ports 11-2-2, the flour is fed from the feed port 11-2-1, so that the flour falls at multiple discharge ports 11-2-2 and is blocked by the screen plate assembly 13. At the same time as the vibration motor 4 is started, the traction mechanism 12 is gradually released, so that the feed slides down the vibrating screen plate 2 at an incline. The flour in the feed hopper 11 is spread on the vibrating screen plate 2 during vibration, thus ensuring that the powdered meat strips do not stick together.

[0038] When the locking knob bolt 13-2 is inserted into one of the limiting holes 13-1-1, the arc-shaped screen plate 13-1 covers multiple discharge ports 11-2-2. When the locking knob bolt 13-2 is inserted into another limiting hole 13-1-1, the arc-shaped screen plate 13-1 moves toward the lower end of the vibrating screen plate 2 to the limit state without interfering with the discharge port 11-2-2, thereby achieving the functional purpose of the screen plate assembly 13 covering or opening the discharge port 11-2-2.

[0039] After rinsing the bottom of the vibrating screen plate 2, the remaining moisture on the bottom plate surface can be dried by the drying mechanism 14. At this time, the upper side of the arc-shaped screen plate 13-1 abuts against the air outlet pipe 14-1, and the notch 13-1-2 moves to the side of the outer shell 11-1 and is not covered by the lower surface of the outer shell 11-1. This allows the arc-shaped screen plate 13-1 to move and guide the airflow, causing the air to flow along the fan 14-2, the hose 14-3, the multiple air outlets of the air outlet pipe 14-1, the space between the outer shell 11-1 and the arc-shaped screen plate 13-1, and the notch 13-1-2, and blown towards the bottom plate of the vibrating screen plate 2 for drying. By setting the cover plate 14-1-1, the outer shell 11-1, the arc-shaped screen plate 13-1, and the cover plate 14-1-1 can form an annular cavity, improving the airflow guiding effect.

[0040] Example 3: A screening method for a vibrating sieve device for a meat powder mixture, comprising the following steps: (S1) Powder spreading process: First, the screen plate assembly 13 covers multiple discharge ports 11-2-2. Flour is fed into the feed hopper 11 through the feed port 11-2-1, so that the flour falls into the multiple discharge ports 11-2-2 and is blocked by the screen plate assembly 13. At the same time as the vibration motor 4 is started, the traction mechanism 12 is gradually released so that the feed hopper 11 slides down along the vibrating screen plate 2 at an incline, so that the flour in the feed hopper 11 is spread on the vibrating screen plate 2 during vibration.
