Description

[0002] Meat jerky is a traditional Chinese flavored meat product. It is a sliced ​​meat product made of marinated and dried pork or beef. It is deeply loved by consumers because of its unique flavor, rich nutrition, strong aroma and easy to carry. In the production process of meat jerky, fresh meat (pork or beef) needs to be sliced ​​and then marinated. The marinated meat slices need to be taken out and drained. The drained meat slices are often dried and dehydrated in a multi-layer constant temperature dryer. After dehydration, the desired meat jerky can be obtained.

[0003] In the existing meat jerky drying process, the meat is usually spread flat on a tray, and then the tray with the meat is placed horizontally in a drying box. The tray has a mesh structure, so that the tray with the mesh structure can effectively increase the surface area of ​​air circulation, which is conducive to the flow of hot air around the meat jerky; thereby accelerating the evaporation and discharge of water and improving the drying efficiency;

[0004] However, when the trays with a mesh structure are drying meat jerky, the water vapor in the meat jerky on the lower tray evaporates; the volatilized water vapor condenses on the lower end surface of the meat jerky on the upper tray, causing the lower end surface of the meat jerky on the upper tray to become moist, affecting the drying uniformity of the upper and lower surfaces of the meat jerky; the upper surface of the meat jerky is too dry and becomes too hard and brittle, losing its original chewiness and taste; and the lower surface of the meat jerky becomes relatively moist due to insufficient drying, affecting the overall shelf life and food safety of the meat jerky, thereby reducing the drying quality of the meat jerky;

[0040] As an embodiment of the present invention, an installation cavity 22 is provided at one end of the installation plate 21 located in the center close to the driving motor 211; the output shaft of the driving motor 211 is rotatably sealed and connected in the installation cavity 22; a bevel gear ring 221 and a bevel gear 222 that mesh with each other are provided in the installation cavity 22; the bevel gear ring 221 is rotatably connected to the inner wall of the installation cavity 22; the bevel gear 222 is fixedly connected to the output shaft of the driving motor 211; two groups of steel ropes 23 are fixedly connected to the surface of the bevel gear ring 221; the ends of the two groups of steel ropes 23 away from the bevel gear ring 221 are respectively connected to the topmost and bottommost two installation plates 21.

[0041] As an embodiment of the present invention, a cavity 24 is provided in the mounting frame 2; a driving ring 241 is slidingly and sealingly connected in the cavity 24; the driving ring 241 is slidingly connected to the output shaft of the driving motor 211; the driving ring 241 is connected to the inner wall of the cavity 24 via a supporting spring 242; a rectangular through groove 243 is provided on the surface of the driving ring 241; a connecting block 244 is rotatably connected in the cavity 24; the connecting block 244 cooperates with the through groove 243; the end of the connecting block 244 away from the driving motor 211 is fixedly connected to the mounting plate 21 located in the center; an electromagnetic ring 245 is inlaid at the end of the cavity 24 away from the driving motor 211.

[0042] As an embodiment of the present invention, a buffer spring 25 is arranged between two adjacent mounting plates 21; the buffer spring 25 is sleeved on the surface of the wire rope 23; a storage groove 251 is opened on one side of the mounting plate 21 close to the buffer spring 25; the buffer spring 25 is fixedly connected in the storage groove 251;

[0043] During operation, when the trays with mesh structures are drying meat jerky, the water vapor in the meat jerky on the lower tray evaporates; the volatilized water vapor condenses on the lower end surface of the meat jerky on the upper tray, causing the lower end surface of the meat jerky on the upper tray to become moist, affecting the drying uniformity of the upper and lower surfaces of the meat jerky; the upper surface of the meat jerky is too dry and becomes too hard and brittle, losing its original chewiness and taste; and the lower surface of the meat jerky becomes relatively moist due to insufficient drying, affecting the overall shelf life and food safety of the meat jerky, thereby reducing the drying quality of the meat jerky;

[0044] In this regard, the present invention sets a driving motor 211 and a mounting plate 21 to cooperate, so that the driving motor 211 can drive the mounting plate 21 to rotate, so that the mounting plate 21 drives the meat jerky on the tray to flip, so that the side of the meat jerky in contact with the tray can face upward due to the flipping, so as to avoid the volatile water vapor from condensing on the lower end surface of the meat jerky, thereby reducing the humidity of the lower end surface of the meat jerky, so that both sides of the meat jerky can be effectively dried, that is, the upper surface of the meat jerky is prevented from becoming too hard and brittle due to excessive drying, and the drying effect of the lower end surface of the meat jerky is improved, and the drying uniformity of the upper and lower end surfaces of the meat jerky is improved, thereby improving the drying and dehydration effect of the meat jerky of the present invention;

[0045] In the initial state, the mounting plate 21 located in the center is rotatably sealed and connected to the mounting frame 2, so that the friction between the mounting plate 21 and the mounting frame 2 is relatively large, which can overcome the problem that the mounting plate 21 with the tray placed thereon deflects due to uneven gravity on both sides; a U-shaped groove is provided at one end of the mounting plate 21 close to the door 11. When the user opens the door 11, the tray with the meat slices needs to be pushed into the U-shaped groove of the mounting plate 21 first, and an empty tray needs to be placed in the mounting plate 21 located at the top; when the two drying chambers 12 are filled with the jerky, the user Close the door 11, and control the operation of the heater 131 and the blower 132 through the control panel, so that the heater 131 heats the hot air in the heating chamber 13, and the blower 132 transports the hot air heated in the heating chamber 13 to the drying chamber 12; the two adjacent mounting plates 21 are in a state of being away from each other under the support of the buffer spring 25, so the hot air can flow between the two mounting plates 21, thereby accelerating the rapid drying of the jerky on the mounting plates 21; since a temperature sensor is installed in the drying chamber 12, When the temperature in the drying chamber 12 is set to a constant temperature range of 55-60°C on the operation control panel; that is, by setting the sensing value of the temperature sensor, such as when the temperature sensor senses that the temperature in the drying chamber 12 is higher than 60°C, the temperature sensor transmits an electrical signal to the heater 131 and controls the heater 131 to stop; and when the temperature sensor senses that the temperature in the drying chamber 12 is lower than 55°C, the temperature sensor transmits an electrical signal to the heater 131, and then controls the heater 131 to operate, so as to achieve the control of the temperature in the drying chamber 12 to maintain a constant temperature state of 55-60°C; in the process of drying the jerky on the mounting rack 2 by the hot air in the drying chamber 12, the moisture in the jerky is evaporated in the form of water vapor, and the volatilized moisture will flow to the heat exchanger 14 with the hot air through the exhaust port 15; since the outside air enters the heating chamber 13 through the heat exchanger 14, the outside air exchanges heat with the hot air discharged from the exhaust port 15 through the heat exchanger 14, thereby improving the thermal energy utilization rate of the hot air discharged from the exhaust port 15, reducing the loss of thermal energy, and improving the practicality of the present invention;

[0046] As the dried meat on the tray is heated and the internal water vapor evaporates, the volatilized water vapor will rise and condense on the lower end surface of the dried meat on the upper tray, causing the lower end surface of the dried meat on the upper tray to become wet, affecting the drying effect of the lower surface of the dried meat; therefore, the dried meat needs to be turned over, and the turning interval can be directly set through the control panel, such as turning over once every half an hour; when the dried meat in the box body 1 needs to be turned over after being dried for half an hour, the control panel will transmit an electrical signal to the drive motor 211 and control the drive motor 211 to run; because in the initial state, the drive ring 241 does not contact with the connecting block 244, and the bevel gear 222 is in contact with the cone gear 224, the bevel gear 222 is in contact with the cone gear 224, and the bevel gear 222 is in contact with the cone gear 224. The gear ring 221 is meshed, and the output shaft of the driving motor 211 is fixedly connected to the bevel gear 222; so that the driving motor 211 can drive the driving bevel gear ring 221 to rotate through the bevel gear 222, and the end of the wire rope 23 away from the mounting plate 21 is connected to the bevel gear ring 221; the rotating bevel gear ring 221 will wrap the wire rope 23 around its surface, so that the ends of the two groups of wire ropes 23 away from the bevel gear ring 221 can pull the upper mounting plate 21 and the lower mounting plate 21 closer to each other; so that the two mounting plates 21 squeeze the buffer spring 25 and contact the mounting plate 21 located in the center, so that the two adjacent mounting plates 21 drive the tray to move it The jerky is clamped between the two adjacent mounting plates 21, and the buffer spring 25 enters the storage groove 251 under the pressure of the mounting plate 21 to ensure that the mounting plate 21 can effectively clamp the jerky. In the process of the two adjacent mounting plates 21 contacting each other, the driving ring 241 is driven by the output shaft of the driving motor 211 to rotate to a state of matching with the connecting block 244, that is, the connecting block 244 corresponds to the through groove 243 of the driving ring 241; then the electromagnetic ring 245 is controlled to be energized so that the electromagnetic ring 245 can generate a magnetic adsorption force on the driving ring 241, so that the driving ring 241 squeezes the supporting spring 242 close to the connecting block 244 under the action of the magnetic adsorption force, so that the connecting block 244 is inserted into The through groove 243 makes the connecting block 244 slidably connected with the driving ring 241; then the driving motor 211 drives the connecting block 244 to rotate through the driving ring 241, so that the connecting block 244 can drive the mounting plate 21 connected thereto to rotate, and at this time, the bevel gear ring 221 rotatably connected with the mounting plate 21 rotates synchronously with respect to the mounting plate 21, and at this time, the wire rope 23 is no longer wound around the bevel gear ring 221, and the mounting plate 21 contacting each other through the wire rope 23 rotates synchronously with the mounting plate 21 located in the center, until after rotating 180°, the mounting plate 21 located above rotates to the bottom, thereby realizing the turning over of the jerky between the mounting plates 21;At this time, the electromagnetic ring 245 is controlled to be powered off, so that the driving ring 241 is pushed away from the connecting block 244 by the restoring force of the supporting spring 242. At this time, the driving motor 211 is controlled to rotate in the opposite direction, so that the driving motor 211 drives the bevel gear ring 221 to rotate in the opposite direction through the bevel gear 222, so that the wire rope 23 wound on the surface of the bevel gear ring 221 is released, so that the mounting plate 21 pulled by the wire rope 23 is reset under the push of the restoring force of the buffer spring 25; and in the process of separation of the two adjacent mounting plates 21, the meat jerky on the tray will fall to the lower tray under the action of gravity. The tray is made of PTFE material, so that the surface of the tray is smooth, which prevents the meat from adhering to the surface of the tray and failing to fall normally, and ensures that the meat on the tray can be effectively turned over, and the meat on the tray can be quickly separated, so that the mounting plate 21 drives the meat below the tray to rise to a lower distance, and the meat has been separated, reducing the time for the meat to be affected by air resistance, thereby reducing the problem of wrinkles caused by the meat falling; ensuring that the meat after turning over can still be laid flat on the tray below, thereby improving the uniformity of drying the meat surface; and also accelerating the drying efficiency of the meat. ;

[0047] As an embodiment of the present invention, a groove 26 is provided on one side of the mounting frame 2 close to the mounting plate 21; two gear shafts 261 are rotatably connected in the groove 26; the two gear shafts 261 are connected by a transmission belt 262 for belt transmission; the inner wall of the transmission belt 262 is fixedly connected with teeth 263 that mesh with the gear shafts 261; a stepper motor 264 is arranged between the two mounting frames 2; the stepper motor 264 is used to drive the gear shaft 261 to rotate; a push rod 265 is arranged at one end of the transmission belt 262 away from the gear shaft 261; the push rod 265 is rotatably connected to the transmission belt 262 through a torsion spring.

[0048] As an embodiment of the present invention, a shift lever 27 is fixedly connected to one side of the mounting frame 2 close to the mounting plate 21 ; a strip groove 271 matching with the shift lever 27 is formed on one side of the mounting plate 21 close to the shift lever 27 .

[0049] As an embodiment of the present invention, a support rod 16 is provided on the side of the mounting frame 2 away from the driving motor 211; a slot 161 is provided on the surface of the support rod 16; an insertion rod 17 is slidably connected in the slot 161; the insertion rod 17 is fixedly connected to the mounting frame 2; a clamping plate 18 is provided between the support rod 16 and the mounting frame 2; the clamping plate 18 is rotatably connected to the support rod 16 through a torsion spring; a clamping groove 181 is provided at one end of the clamping plate 18 close to the mounting frame 2; the mounting plate 21 is slidably connected in the clamping groove 181; the clamping plate 18 is rotatably connected to the support rod 16;

[0050] During operation, if more mounting plates 21 are arranged, the compression strength of the buffer spring 25 above the mounting plate 21 located in the center will increase as it approaches the mounting plate 21 located in the center, that is, the distance between the two adjacent mounting plates 21 of the mounting plate 21 above the mounting plate 21 located in the center will decrease as it approaches the mounting plate 21 located in the center, which will cause the distance between the mounting plate 21 located in the center and the mounting plate 21 above it to be smaller, resulting in a decrease in ventilation volume, thereby affecting the drying effect of the jerky on the upper end of the mounting plate 21 located in the center. In this regard, the present invention provides a transmission belt 262 and push rod 265. When the steel wire 23 pulls the upper mounting plate 21 and the lowermost mounting plate 21 closer to each other, the mounting plate 21 pulled by the steel wire 23 will push the push rod 265 to overcome the torsion force of the torsion spring and rotate downward while squeezing the buffer spring 25. At this time, the mounting plate 21 passes over the push rod 265 and descends and contacts each other. During the flipping process, the push rod 265 that blocks the flipping of the mounting plate 21 will be pushed by the mounting plate 21 to overcome the torsion force of the torsion spring and rotate until the mounting plate 21 is flipped, and the stepper motor 264 is controlled to rotate so that the stepper motor 264 can The driving belt 262 is able to drive the push rod 265 to rise, so that when the push rod 265 is inserted between two adjacent mounting plates 21, the push rod 265 can push the mounting plates 21 to rise until the mounting plates 21 rise to the corresponding gear rods 27, and the corresponding gear rods 27 will block the mounting plates 21 to prevent the mounting plates 21 from continuing to rise. Since a strip groove 271 is provided on one side of the mounting plate 21 close to the gear rod 27, the strip groove 271 is provided to prevent the mounting plates 21 from rising to the corresponding gear rods 27 before other gear rods 27 pass through the strip groove 271. The mounting plate 21 is prevented from being blocked by other stop bars 27, so as to ensure that the stop bars can effectively block the corresponding mounting plate 21; the blocked mounting plate 21 will squeeze the push rod 265 to overcome the torsion of the torsion spring and rotate downward. When the mounting plate 21 passes over the push rod 265, the push rod 265 below it will block the mounting plate 21 again, so as to ensure that the mounting plate 21 is stable at the set height, until the push rod 265 cooperates with the stop bar 27 to stabilize the upper mounting plate 21 at the set height; since the mounting plate 21 located in the center is only rotatably connected to the mounting frame 2 at one end;When there are a large number of mounting plates 21, the center mounting plate 21 will be subjected to uneven force, causing the center of gravity to tilt. To this end, the present invention provides a support rod 16. When the user needs to put the tray into the center mounting plate 21, the user needs to first remove the support rod 16, then put the tray into the center mounting plate 21, and then align the two sides of the support rod 16 with the insertion rod 17. When the insertion rod 17 is inserted into the slot 161, the support rod 16 is installed on the mounting frame 2 and is parallel to and directly opposite the center mounting plate 21. As the support rod 16 is pushed, the support rod 16 drives the clamping plate 18 to approach the center mounting plate 21.
