Description

TECHNICAL FIELD

[0001] The present application relates to the drying technical field, and in particular to a continuous drying equipment for food processing and a use method thereof. BACKGROUND

[0002] In the process of food production and processing, it is necessary to dry the food in order to facilitate the storage in the later period. For example, egg dry is a new type of food processed from whole egg yolk or egg white, and has a texture and color similar to traditional bean curd, which can be used as a snack, and can also be used to cook various delicacies, such as making cold dish platter, scalding hot pot, frying, soup, dry pot, etc.

[0003] The existing drying equipment (such as the multi-layer continuous drying device for egg dry disclosed in the utility model with the publication number CN217715812U) still has some deficiencies in the process of use:

[0004] 1. The above technical solution places the egg dry by the shovel and then rotates to turn over the egg dry for drying. However, after the shovel is rotated to a certain angle, the egg dry will slide down the conveying belt along the shovel, which not only cannot effectively turn over the egg dry, but also easily breaks the egg dry during the sliding process.

[0005] 2. When the shovel turns over the egg dry, the conveying speed of the subsequent conveying belt to the egg dry needs to be accurately controlled, otherwise when the shovel turns over the next batch of egg dry, the shovel may press the egg dry, resulting in damage to the egg dry.

[0006] In view of the above problems, the present application file proposes a continuous drying equipment for food processing and a use method thereof. SUMMARY

[0007] The purpose of the present application is to solve the problems that the existing shovel cannot smoothly turn over the egg dry and easily breaks the egg dry, and the shovel easily presses the egg dry during the turning over process of the egg dry. A continuous drying equipment for food processing and a use method thereof are proposed.

[0008] In order to achieve the above purpose, the present application adopts the following technical solutions:

[0009] The utility model provides a kind of continuous drying equipment for food processing, including rack, second rotating roller and two first rotating rollers are rotationally connected in the rack, fixed column is fixed in the rack, fixed column is located in the middle of two first rotating rollers, and the height of fixed column is lower than the height of first rotating roller, second rotating roller is located in the just below of fixed column, the outer wall of fixed column is rotationally sleeved with multiple guide rollers, two first rotating rollers are sleeved with same hollow metal conveyor belt, the inside bottom of second rotating roller is contacted with hollow metal conveyor belt, multiple guide rollers are contacted with the outside surface of hollow metal conveyor belt, for transporting egg dry;

[0010] Further comprising multiple connecting arms, multiple connecting arms are rotationally sleeved on the outer wall of fixed column, and multiple connecting arms are located between adjacent two guide rollers respectively, one guide rod is rotationally penetrated in multiple connecting arms, and rotating shovel is fixed on the side of multiple connecting arms, and guide rod cooperates with connecting arm to turn over egg dry;

[0011] Further comprising baffle, which is arranged above hollow metal conveyor belt, for blocking subsequent egg dry when turning over, both sides of the rack are provided with moving frame, and the rack is provided with drying structure for drying egg dry on hollow metal conveyor belt;

[0012] Wherein, discharge plate is slidably connected in the rack, and discharge plate cooperates with first rotating roller on left side to carry egg dry;

[0013] Turnover structure is arranged on fixed column, for driving guide roller to turn over egg dry;

[0014] Two groups of driving structures are arranged on both sides of the rack respectively, for synchronously driving turnover structure to run;

[0015] Rocking structure is arranged in the rack, for driving discharge plate to rock egg dry on it.

[0016] In a possible design, the drying structure includes a heating box fixed in the rack, and the heating box is located below the hollow metal conveyor belt, a plurality of carbon resistance wire heating sheets are fixed on the inner wall of the bottom of the heating box for heating air, a plurality of air blowers are fixed on one side of the heating box for blowing the heated air towards the hollow metal conveyor belt, and a plurality of air outlets are arranged on the top of the heating box for making the hot air flow upwards; the air blowers blow the air heated by the carbon resistance wire heating sheets in the heating box upwards, so that the front and back surfaces of the egg dry can be dried through the hollow metal conveyor belt, and the hot air blown out of the air outlets can also blow to the discharge plate to heat the discharge plate, so that the egg dry can be further dried when the discharge plate rocks the egg dry later.

[0017] In one possible design, the perforated metal conveyor belt is V-shaped under the action of the second rotating roller, two first rotating rollers, and multiple guide rollers, so that the dried egg can move smoothly onto the rotating shovel.

[0018] In one possible design, the flipping structure includes multiple annular grooves on the outer wall of the fixed column, and multiple connecting arms each having a groove. The annular grooves are respectively located within corresponding grooves. The inner walls of the annular grooves on opposite sides each have a first trajectory groove and a second trajectory groove, with the second trajectory groove communicating with the first trajectory groove. A pin is slidably disposed within one of the two first trajectory grooves. A push rod is rotatably sleeved on the outer wall of the pin. The first and second trajectory grooves cooperate with the pin to drive the push rod to move outward. One end of the push rod slidably passes through the connecting arm and is fixed to a push plate. The push plate is slidably disposed on the top of the rotating shovel for loading the shovel. The dried egg is pushed out. The top of the rotating shovel has two L-shaped baffles fixed on it, and the two L-shaped baffles are located on both sides of the push plate to limit the dried egg. The cam drives the connecting arm and the rotating shovel to rotate through the guide rod. During the rotation of the rotating shovel, the L-shaped baffles restrict the dried egg to prevent it from falling off the rotating shovel. When the rotating shovel rotates to the hollow metal conveyor belt on the other side, the pin moves from the first track groove to the second track groove. The cooperation between the pin and the second track groove pushes the push rod and the push plate outward, pushing the dried egg on the rotating shovel to one side, so that the dried egg can fall onto the hollow metal conveyor belt. At this time, the turning operation of the dried egg is completed.

[0019] In one possible design, the drive structure includes a support plate fixed to one side of the frame, and a movable frame slidably disposed on the top of the support plate. First racks are fixed to the top and bottom inner walls of the movable frame. One end of the second rotating roller rotatably passes through the frame and is fixed with a residual gear, which is located inside the movable frame and intermittently meshes with the two first racks. A rotating shaft is rotatably connected to one side of the frame, and the rotating shaft is coaxial with a fixed column. A cam is fixedly fitted onto the outer wall of the rotating shaft. One end of a guide rod is fixedly connected to the side of the cam off-center. The cam drives the connecting arm to rotate via the guide rod. A spur gear is fixed to the end of the rotating shaft away from the frame. A second rack is fixed to the top of the movable frame via a support rod, and the second rack meshes with the spur gear. During operation, the second rotating roller drives the movable frame and the second rack to reciprocate linearly through the engagement of the residual gear and the first rack. The second rack meshing with the spur gear drives the rotating shaft and the cam to rotate counterclockwise. The cam drives the connecting arm and the rotating shovel to rotate via the guide rod, thereby driving the rotating shovel to perform inter-rotational turning operations.

[0020] In one possible design, the turbulent structure includes a rotating shaft that rotates within a frame, located below a first rotating roller. Multiple rolling wheels are fixedly fitted onto the outer wall of the rotating shaft. These rolling wheels cooperate with a perforated metal conveyor belt to drive the rotating shaft. A horizontal plate is fixed within the frame, located below the rotating shaft. Multiple L-shaped plates slide through the horizontal plate, positioned between adjacent rolling wheels. The top ends of each L-shaped plate are fixedly connected to the bottom of a discharge plate. A sliding rod is fixed to the top of one side of each L-shaped plate, with its top end sliding through the horizontal plate. The outer walls of each sliding rod are fitted with a component fixedly connected to the bottom of the horizontal plate. The first spring, with its bottom end fixedly connected to the L-shaped plate, is used to drive the L-shaped plate to move down and reset. Each of the L-shaped plates has a paddle fixed on the side near the rotating shaft. The outer wall of the rotating shaft is fixedly fitted with multiple levers, and the levers cooperate with the paddles to drive the L-shaped plates to move up. When the dried egg falls onto the discharge plate, the perforated metal conveyor belt drives the rotating shaft and the rolling wheel to rotate clockwise. The rotating shaft pushes the L-shaped plate to move up intermittently through the cooperation of the levers and paddles, thereby slightly shaking the dried egg on the discharge plate. The hot air ejected from the vent can also blow onto the discharge plate to heat it. When the discharge plate shakes the dried egg later, it can further dry the dried egg.

[0021] In one possible design, the top of the frame is provided with two sliding grooves, and a partition is slidably disposed in the two sliding grooves. Both sides of the sliding grooves are rotatably connected to connecting rods via pins, and the bottom end of the connecting rods is rotatably connected to the top of the adjacent moving frame. When the moving frame and the second rack work together to drive the rotating shovel to flip the dried egg, the moving frame drives the partition to move down through the connecting rods to block the subsequent dried egg. Conversely, after the rotating shovel is reset, the partition moves up to release the obstruction of the dried egg, thereby preventing the rotating shovel from causing squeezing damage to the dried egg when flipping it.

[0022] In one possible design, the top two sides of the frame are provided with two clearance arc grooves for the guide rods to make way.

[0023] In one possible design, the frame has two inclined slots, each containing a fixed rod. A common blocking rod slides through the outer walls of both fixed rods. A second spring, fixedly connected to the blocking rod, is fitted onto the outer walls of both fixed rods. The bottom end of the second spring is fixedly connected to one side of the inner wall of the inclined slot. The blocking rod is located between the discharge plate and the first rotating roller, used to flip the dried egg pieces that fall onto the discharge plate. The outer wall of the blocking rod has multiple stripes to increase the friction between the blocking rod and the dried egg pieces. After the dried egg pieces are flipped and dried, the perforated metal conveyor belt continues to transport them to the left and drop them. One side of the dried egg pieces abuts against the blocking rod. The blocking rod moves diagonally downwards under the pressure of the dried egg pieces, compressing the second spring. The blocking rod then drives one side of the dried egg pieces towards the first rotating roller, while the perforated metal conveyor belt continues to transport the dried egg pieces. Therefore, the blocking rod allows the dried egg pieces to be flipped and fall onto the discharge plate, completing the flipping process again.

[0024] This application discloses a method of using a continuous drying device for food processing, comprising the following steps:

[0025] S1. Egg curd feeding and initial conveying: The egg curd is placed on a hollow metal conveyor belt, and the V-shaped structure formed by the first rotating roller, the second rotating roller and the guide roller guides the egg curd to the left and conveys it to the rotating shovel;

[0026] S2. Egg Dried Tofu Turning Mechanism: When the second rotating roller is running, it drives the moving frame and the second rack to move back and forth through the cooperation of the residual gear and the first rack, thereby driving the rotating shaft and cam to rotate counterclockwise; the cam causes the rotating shovel to rotate through the guide rod, and the L-shaped baffle prevents the egg dried tofu from falling; when the rotating shovel flips, the change in the pin trajectory pushes the push rod and push plate to push the egg dried tofu onto the conveyor belt, completing the flipping;

[0027] S3. Egg drying process: During the conveying process, the blower blows hot air from the heating box onto the dried eggs to dry them on both sides. At the same time, the hot air also heats the discharge plate in preparation for subsequent drying.

[0028] S4. Partition Blocking and Releasing: When the spur gear rotates counterclockwise, the moving frame drives the connecting rod to lower the partition, blocking the subsequent dried egg; when the rotating shovel rotates in the opposite direction, the partition rises, releasing the blockage.

[0029] S5. Final turning and discharge of dried egg: The dried egg continues to be conveyed. After touching the blocking bar, it moves diagonally downward and turns over to fall onto the discharge plate. The L-shaped plate is moved aside by the action of the spring to prevent the dried egg from being damaged.

[0030] S6. Dried egg pieces on the discharge plate are shaken and dried: When the dried egg pieces fall onto the discharge plate, the perforated metal conveyor belt drives the rolling wheels to rotate. Through the cooperation of the lever and the lever plate, the L-shaped plate is moved up intermittently, and the dried egg pieces are shaken slightly to accelerate the drying process.

[0031] Beneficial effects:

[0032] In this invention, the outer wall of the fixed column is provided with multiple annular grooves. The inner wall of each annular groove on the side away from each other is provided with a first track groove and a second track groove. A pin is slidably arranged in the two first track grooves. A push rod is rotatably sleeved on the outer wall of the pin. A push plate is fixed to one end of the push rod. Two L-shaped baffles are fixed to the top of the rotating shovel. The cam drives the connecting arm and the rotating shovel to rotate through the guide rod. During the rotation, the L-shaped baffles can prevent the dried egg from falling off the rotating shovel. The pin moves from the first track groove to the second track groove. The cooperation between the pin and the second track groove pushes the push rod and the push plate outward, pushing the dried egg on the rotating shovel to one side, so that the dried egg can fall steadily onto the hollow metal conveyor belt, ensuring that the dried egg is intact during the flipping process.

[0033] In this invention, a residual gear is fixed to one end of the second rotating roller, and the residual gear intermittently meshes with two first racks. A cam is fixed to one side of the frame via a rotating shaft, and one end of the guide rod is fixedly connected to the cam. A spur gear is fixed to the end of the rotating shaft away from the frame. A second rack is fixed to the top of the moving frame via a support rod. When the second rotating roller is running, the moving frame and the second rack reciprocate linearly through the engagement of the residual gear and the first racks. The second rack meshes with the spur gear, causing the rotating shaft and the cam to rotate counterclockwise. The cam drives the connecting arm and the rotating shovel to rotate via the guide rod, which is used to drive the rotating shovel to perform the flipping operation.

[0034] In this invention, the top of the frame is provided with two sliding grooves, and a partition is slidably disposed in the two sliding grooves. Both sides of the sliding grooves are rotatably connected to connecting rods via pins, and the bottom end of the connecting rod is rotatably connected to the top of the adjacent moving frame. When the moving frame and the second rack work together to drive the rotating shovel to flip the dried egg, the moving frame drives the partition to move down through the connecting rods to block the subsequent dried egg. Conversely, after the rotating shovel is reset, the partition moves up to release the obstruction of the dried egg, thereby preventing the rotating shovel from causing squeezing damage to the dried egg when flipping it.

[0035] In this invention, the operation of the perforated metal conveyor belt enables the rotating shovel to complete the flipping operation of the dried egg, and the dried egg can fall intact onto the perforated metal conveyor belt during the flipping process, avoiding damage to the perforated metal conveyor belt. In addition, during the flipping process, the partition can be controlled to block and release the subsequent dried egg in time, so that the rotating shovel can smoothly receive the dried egg and flip it later.

[0048] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0049] Example 1

[0050] Reference Figure 1 and Figure 2 This continuous drying equipment is used in the food processing industry. The equipment mainly includes a frame 1, in which a second rotating roller 3 and two first rotating rollers 2 are rotatably connected. A fixed column 4 is fixed inside the frame 1, located between the two first rotating rollers 2, and the height of the fixed column 4 is lower than the height of the first rotating rollers 2. The second rotating roller 3 is located directly below the fixed column 4. Multiple guide rollers 5 are rotatably sleeved on the outer wall of the fixed column 4. The two first rotating rollers 2 are sleeved on the same hollow metal conveyor belt 6. The second rotating roller 3 is in contact with the inner bottom of the hollow metal conveyor belt 6, and the multiple guide rollers 5 are in contact with the outer side of the hollow metal conveyor belt 6. It is mainly used for transporting dried eggs.

[0051] A motor protective housing 48 is fixedly installed on one side of the frame 1. A motor is installed inside the motor protective housing 48. The output shaft of the motor passes through the frame 1 and is fixedly connected to one of the first rotating rollers 2. The motor drives the first rotating roller 2 to rotate. The first rotating roller 2 drives the hollow metal conveyor belt 6 to rotate. Under the action of the hollow metal conveyor belt 6, the second rotating roller 3 and the guide roller 5 are driven to rotate.

[0052] In the specific implementation process, the hollow metal conveyor belt 6 forms a V shape under the action of the second rotating roller 3, the two first rotating rollers 2 and multiple guide rollers 5, so that the dried egg can move smoothly onto the rotating shovel 25 to achieve the flipping function.

[0053] Reference Figure 2 and Figure 6 In order to achieve the function of turning the dried egg, the equipment also includes multiple connecting arms 24. These connecting arms 24 are rotatably sleeved on the outer wall of the fixed column 4 and are respectively located between two adjacent guide rollers 5. The same guide rod 18 is rotatably passed through the multiple connecting arms 24. A rotating shovel 25 is fixed on one side of each connecting arm 24. The guide rod 18 cooperates with the connecting arm 24 to turn the dried egg over when turning it over.

[0054] Reference Figure 1 and Figure 2 In order to block the subsequent dried egg pieces, a partition 22 is installed above the perforated metal conveyor belt 6. When the dried egg pieces are turned over, the partition 22 can block the subsequent dried egg pieces, ensuring the smooth progress of the turning process.

[0055] Reference Figure 1 and Figure 2 The frame 1 has movable frames 13 on both sides. The frame 1 also has a drying structure for drying the dried eggs on the perforated metal conveyor belt 6. The drying structure specifically includes a heating box 7 fixed inside the frame 1. The heating box 7 is located below the perforated metal conveyor belt 6. Multiple carbon fiber heating plates 8 are fixed on the bottom inner wall of the heating box 7 for heating air. Multiple blowers 9 are fixed on one side of the heating box 7 for blowing the heated air toward the perforated metal conveyor belt 6. Multiple air outlets 10 are provided on the top of the heating box 7 so that the hot air can flow upward and dry the front and back of the dried eggs through the perforated metal conveyor belt 6.

[0056] Specifically, the blower 9 blows the air heated by the carbon wire heating plate 8 in the heating box 7 upwards, and dries the front and back of the dried egg through the hollow metal conveyor belt 6. The hot air sprayed from the air outlet 10 can also blow onto the discharge plate 33 to heat the discharge plate 33. When the discharge plate 33 shakes the dried egg in the later stage, it can further dry the dried egg and improve the drying effect.

[0057] Reference Figures 4-7To achieve continuous transport and turning of the dried egg, a turning structure is also provided inside the frame 1. This structure is mounted on the fixed column 4 and is used to drive the guide roller 5 to turn the dried egg. The turning structure includes multiple annular grooves 27 on the outer wall of the fixed column 4. Each connecting arm 24 has a groove 47. The annular grooves 27 are respectively located within the corresponding grooves 47. The inner walls of the annular grooves 27 on opposite sides are provided with a first track groove 28 and a second track groove 29. The second track groove 29 is connected to the first track groove 28. A pin 30 is slidably disposed in a track groove 28. A push rod 31 is rotatably sleeved on the outer wall of the pin 30. The first track groove 28 and the second track groove 29 cooperate with the pin 30 to drive the push rod 31 to move outward. One end of the push rod 31 slides through the connecting arm 24 and is fixed with a push plate 32. The push plate 32 is slidably disposed on the top of the rotating shovel 25 to push out the dried egg on it. Two L-shaped baffles 26 are fixed on the top of the rotating shovel 25. The two L-shaped baffles 26 are located on both sides of the push plate 32 to limit the dried egg.

[0058] Specifically, the cam 17 drives the connecting arm 24 and the rotating shovel 25 to rotate via the guide rod 18. During the rotation of the rotating shovel 25, the L-shaped baffle 26 restricts the dried egg and prevents it from falling off the rotating shovel 25. When the rotating shovel 25 rotates to the hollow metal conveyor belt 6 on the other side, the pin 30 moves from the first track groove 28 to the second track groove 29. The cooperation between the pin 30 and the second track groove 29 pushes the push rod 31 and the push plate 32 outward, pushing the dried egg on the rotating shovel 25 to one side, so that the dried egg falls onto the hollow metal conveyor belt 6, thus completing the turning operation of the dried egg.

[0059] Reference Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 Meanwhile, the equipment is also equipped with two sets of drive structures, which are respectively set on both sides of the frame 1 for synchronously driving the flipping structure. The drive structure includes a support plate 12 fixed on one side of the frame 1, a moving frame 13 slidably set on the top of the support plate 12, and a first rack 14 fixed on the top inner wall and bottom inner wall of the moving frame 13. One end of the second rotating roller 3 rotates through the frame 1 and is fixed with a residual gear 11. The residual gear 11 is located in the moving frame 13 and intermittently meshes with the two first racks 14. A rotating shaft 16 is rotatably connected to one side of the frame 1. The rotating shaft 16 is coaxial with the fixed column 4. A cam 17 is fixedly sleeved on the outer wall of the rotating shaft 16. One end of the guide rod 18 is fixedly connected to the side of the cam 17 that is off-center. The cam 17 drives the connecting arm 24 to rotate through the guide rod 18. A spur gear 19 is fixed to the end of the rotating shaft 16 away from the frame 1. A second rack 15 is fixed to the top of the moving frame 13 through a support rod. The second rack 15 meshes with the spur gear 19.

[0060] Specifically, when the second rotating roller 3 is running, it drives the moving frame 13 and the second rack 15 to reciprocate linearly through the cooperation of the residual gear 11 and the first rack 14. The second rack 15 meshes with the spur gear 19, which drives the rotating shaft 16 and the cam 17 to rotate counterclockwise. The cam 17 drives the connecting arm 24 and the rotating shovel 25 to rotate through the guide rod 18, which is used to drive the rotating shovel 25 to perform the turning operation.

[0061] Reference Figure 2 , Figure 8 and Figure 9 To further improve the drying effect, the equipment is also equipped with a tumbling structure, which is set inside the frame 1 to drive the discharge plate 33 to tumble the dried eggs on it. The discharge plate 33 is slidably connected inside the frame 1 and cooperates with the first rotating roller 2 located on the left side to support the dried eggs. The tumbling structure includes a rotating shaft 38 that rotates inside the frame 1. The rotating shaft 38 is located below the first rotating roller 2. Multiple rolling wheels 46 are fixedly sleeved on the outer wall of the rotating shaft 38. The rolling wheels 46 cooperate with the perforated metal conveyor belt 6 to drive the rotating shaft 38 to rotate. A horizontal plate 34 located below the rotating shaft 38 is fixed inside the frame 1. Multiple L-shaped plates 35 slide through the horizontal plate 34. Multiple L-shaped plates 35 are located between two adjacent rolling wheels 46. The top of each L-shaped plate 35 is fixedly connected to the bottom of the discharge plate 33. A sliding rod 36 is fixedly fixed on one side of each L-shaped plate 35. The top of the sliding rod 36 slides through the horizontal plate 34. A first spring 37 is sleeved on the outer wall of each sliding rod 36 and fixedly connected to the bottom of the horizontal plate 34. The bottom end of the first spring 37 is fixedly connected to the L-shaped plate 35 and is used to drive the L-shaped plate 35 to move down and reset. A paddle 40 is fixedly fixed on the side of each L-shaped plate 35 near the rotating shaft 38. Multiple levers 39 are fixedly sleeved on the outer wall of the rotating shaft 38. The levers 39 cooperate with the paddles 40 and are used to drive the L-shaped plate 35 to move up.

[0062] Specifically, when the dried egg falls onto the discharge plate 33, the perforated metal conveyor belt 6 drives the rotating shaft 38 and the rolling wheel 46 to rotate clockwise. The rotating shaft 38, through the cooperation of the lever 39 and the lever 40, pushes the L-shaped plate 35 to move up intermittently, thereby slightly shaking the dried egg on the discharge plate 33. At the same time, the hot air sprayed from the air outlet 10 can blow towards the discharge plate 33 to heat the discharge plate 33. When the discharge plate 33 shakes the dried egg later, it can further dry the dried egg.

[0063] Through the above implementation methods, the continuous drying equipment for food processing can realize the automatic turning, moving and shaking of dried eggs, thereby improving drying efficiency and quality.

[0064] Reference Figure 3 and Figure 4The top of the frame 1 is provided with two sliding grooves 21, and a partition 22 is slidably installed in the sliding grooves 21. Both sides of the sliding grooves 21 are rotatably connected to the connecting rods 23 by pins. The bottom end of the connecting rods 23 is rotatably connected to the top of the adjacent moving frame 13. When the moving frame 13 and the second rack 15 cooperate to drive the rotating shovel 25 to turn the dried egg over, the moving frame 13 will drive the partition 22 to move downward through the connecting rods 23, thereby blocking the subsequent dried egg. The purpose of this design is to avoid the rotating shovel 25 from squeezing and damaging the dried egg while turning it over. When the rotating shovel 25 returns to its original position, the partition 22 moves upward, releasing the obstruction of the dried egg, so that the equipment can continuously dry and turn the dried egg.

[0065] Reference Figure 3 Furthermore, two clearance arc grooves 20 are provided on both sides of the top of the frame 1. These two clearance arc grooves 20 are used to make way for the guide rod 18, ensuring that the guide rod 18 will not be obstructed by the frame 1 during movement, thereby ensuring the normal operation of the equipment.

[0066] Example 2

[0067] refer to Figure 11 Improvements based on Example 1: In addition, the frame 1 is provided with two inclined slot holes 41, and a fixing rod 42 is fixed in the inclined slot hole 41. The outer wall of the two fixing rods 42 slides through the same blocking rod 43, and the outer wall of the blocking rod 43 is provided with multiple striped patterns 45 to increase the friction between the blocking rod 43 and the dried egg. The outer wall of the fixing rod 42 is also fitted with a second spring 44 fixedly connected to the blocking rod 43. The bottom end of the second spring 44 is fixedly connected to one side of the inner wall of the inclined slot hole 41. The blocking rod 43 is located between the discharge plate 33 and the first rotating roller 2 and is used to flip the dried egg that falls on the discharge plate 33.

[0068] Specifically, after the dried egg is turned over and dried on the equipment, the perforated metal conveyor belt 6 will continue to convey it to the left and drop it. At this time, one side of the dried egg will abut against the blocking rod 43, causing the blocking rod 43 to move diagonally downward under the pressure of the dried egg, while compressing the second spring 44. The movement of the blocking rod 43 will drive one side of the dried egg to move towards the first rotating roller 2, while the perforated metal conveyor belt 6 continues to convey the dried egg. Through this design, the blocking rod 43 can make the dried egg turn over and drop it onto the discharge plate 33, thus completing the turning operation of the dried egg again. This design not only improves the drying efficiency of the equipment, but also ensures the drying quality of the dried egg.

[0069] A method of using a continuous drying equipment for food processing includes the following steps:

[0070] S1. Place the dried egg on the perforated metal conveyor belt 6. The motor drives the first rotating roller 2 to rotate. The first rotating roller 2 drives the perforated metal conveyor belt 6 to rotate. Under the action of the perforated metal conveyor belt 6, the second rotating roller 3 and the guide roller 5 rotate. The perforated metal conveyor belt 6 conveys the dried egg to the left. Since the perforated metal conveyor belt 6 forms a V shape under the action of the first rotating roller 2, the second rotating roller 3 and the guide roller 5, the dried egg can move smoothly onto the rotating shovel 25 during the conveying process.

[0071] S2. Additionally, during operation, the second rotating roller 3 drives the moving frame 13 and the second rack 15 to reciprocate linearly through the engagement of the residual gear 11 and the first rack 14. The second rack 15 meshes with the spur gear 19, causing the rotating shaft 16 and the cam 17 to rotate counterclockwise. The cam 17 drives the connecting arm 24 and the rotating shovel 25 to rotate through the guide rod 18. During the rotation of the rotating shovel 25, the L-shaped baffle 26 restricts the dried egg pieces to prevent them from falling off the rotating shovel 25. When the rotating shovel 25 rotates to the hollow metal conveyor belt 6 on the other side, the pin 30 moves from the first track groove 28 to the second track groove 29. The engagement of the pin 30 and the second track groove 29 pushes the push rod 31 and the push plate 32 outward, pushing the dried egg pieces on the rotating shovel 25 to one side, thus allowing the dried egg pieces to fall onto the hollow metal conveyor belt 6. At this point, the turning operation of the dried egg pieces is completed.

[0072] S3. When the perforated metal conveyor belt 6 transports the dried egg, the blower 9 blows the air heated by the carbon wire heating plate 8 in the heating box 7 upward, so that the perforated metal conveyor belt 6 can dry the front and back of the dried egg. The hot air sprayed from the air outlet 10 can also blow towards the discharge plate 33 to heat the discharge plate 33. When the discharge plate 33 shakes the dried egg in the later stage, it can further dry the dried egg.

[0073] S4. In addition, while the spur gear 19 rotates counterclockwise, the moving frame 13 drives the connecting rod 23 to move to the left. The connecting rod 23 pulls the partition plate 22 downward, so that the partition plate 22 moves to the top of the hollow metal conveyor belt 6. Therefore, when the rotating shovel 25 flips the dried egg, the partition plate 22 blocks the subsequent dried egg. When the spur gear 19 and the guide rod 18 drive the rotating shovel 25 to rotate in the opposite direction, the partition plate 22 moves upward, releasing the obstruction of the dried egg, making it easier for the rotating shovel 25 to flip the subsequent dried egg (this step is auxiliary and can be omitted, i.e., the partition plate 22 can be omitted).

[0074] S5. After the dried egg is turned over and dried, the perforated metal conveyor belt 6 continues to transport it to the left and drop it. One side of the dried egg touches the blocking rod 43. The blocking rod 43 moves diagonally downward under the pressure of the dried egg, and the second spring 44 is compressed. The blocking rod 43 drives one side of the dried egg to move towards the first rotating roller 2. The perforated metal conveyor belt 6 continues to transport the dried egg. Therefore, the blocking rod 43 can turn the dried egg over and drop it onto the discharge plate 33, completing the turning operation of the dried egg again. When the dried egg falls onto the discharge plate 33, the L-shaped plate 35 plays a certain role in giving way under the action of the first spring 37, which can prevent the dried egg from being damaged on the discharge plate 33. After drying, both sides of the discharge plate 33 are relatively tough, and the dried egg can fall intact onto the discharge plate 33.

[0075] S6. When the dried egg falls onto the discharge plate 33, the perforated metal conveyor belt 6 drives the rotating shaft 38 and the rolling wheel 46 to rotate clockwise. The rotating shaft 38 pushes the L-shaped plate 35 to move up intermittently through the cooperation of the lever 39 and the lever 40, thereby slightly shaking the dried egg on the discharge plate 33 to further accelerate the drying process of the dried egg.

[0076] However, as is well known to those skilled in the art, the working principle and wiring method of the carbon resistance wire heating element 8 and the blower 9 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0077] 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.
