Description

Technical Field

[0001] The invention belongs to the technical field of beef jerky baking ovens, and more specifically, particularly relates to an automatic temperature-adjusting beef jerky baking oven. Background Art

[0002] Beef is the second most popular meat food for Chinese people, second only to pork. Beef has a high protein content and a low fat content. It is delicious and popular, and is known as the "pride of meat". Beef jerky contains a variety of minerals and amino acids needed by the human body, which not only maintains the chewy flavor of beef, but also keeps it from deteriorating over time. The production of beef jerky first requires the selection of high-quality raw materials, followed by the production process and production time. When drying, the sunshine time must also be considered. Each process must be closely controlled. In actual application, beef jerky baking ovens usually require the following technologies:

[0003] 1. Precise temperature control system, capable of accurately setting and maintaining the required baking temperature;

[0004] 2. Good hot air circulation system ensures uniform temperature distribution in the furnace;

[0005] 3. Efficient heating elements provide stable heat output;

[0006] 4. Reasonable furnace structure design facilitates heat transfer and material loading and unloading;

[0007] 5. Advanced humidity control device to control the moisture content during baking.

[0008] At present, manufacturers use a variety of baking ovens and methods to bake beef jerky. Some manufacturers use traditional electric heating baking ovens to bake through resistance wire heating, and some manufacturers use gas baking ovens, using the heat generated by gas combustion. Some manufacturers use infrared heating baking ovens, which use infrared radiation for heating. In the existing beef baking and heating, there are usually many problems.

[0009] Firstly, the structural design of the baking equipment is relatively simple, and the baking racks are mostly fixed. This means that the beef can only be heated on one side during the baking process, and the heat distribution is extremely uneven, resulting in obvious differences in the heating of different parts of the beef, affecting the baking effect. It is easy to cause some of the beef to be over-baked and burnt, while the other part does not reach the ideal baking degree, reducing the quality and taste of the product.

[0010] Secondly, in the existing baking equipment, there are many thorny problems in the removal operation of the rack. Usually, the baking rack for placing beef lacks a convenient ejection mechanism and relies entirely on manual dragging, which not only greatly increases the labor intensity of the operator, but also is inefficient. Due to the lack of effective auxiliary devices, the operator often needs to operate with difficulty in a narrow space when removing the rack, which can easily cause physical fatigue and accidental injuries.

[0011] In view of this, the existing structure and defects are studied and improved, and an automatic temperature-adjusting beef jerky baking oven is provided, in order to achieve a more practical purpose. Summary of the invention

[0012] In order to solve the above technical problems, the present invention provides a beef jerky baking oven with automatic temperature control to solve the above problems.

[0018] Preferably, the upper end of the rotating seat is slidably connected with a sliding block, and the inner part of the sliding block is threadedly connected with two threaded rods.

[0019] Preferably, the outer surfaces of the motor and the two threaded rods are sleeved with synchronous wheels, and the outer surfaces of the two groups of synchronous wheels are sleeved with synchronous belts.

[0020] Preferably, two push rods are fixedly connected to the upper end of the sliding block, and a heat insulation plate is sleeved on the outer surface of the baking rack.

[0021] Preferably, two groups of L-shaped bases are fixedly connected to the outer surface of the baking rack, and springs are sleeved on the inner surfaces of the two groups of L-shaped bases.

[0022] Preferably, rectangular limit blocks are fixedly connected to the outer surfaces of the two groups of springs.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] In the present invention, a cylinder is provided. During the baking and heating process, the control box controls the extension of the cylinder output shaft, and the stroke of the cylinder output shaft is divided into four sections. The extension of the cylinder output shaft drives the rack to slide on the upper end of the bottom plate. During the sliding process of the rack, the meshing gear drives the baking rack connected to the rotating seat to rotate. By controlling the extension distance of the cylinder, the baking rack is driven to rotate ninety degrees at each start-up. After four starts, the baking rack is driven to rotate nearly one circle. At this time, the controller in the control box controls the cylinder output shaft to start intermittent contraction. The extension and contraction of the cylinder output shaft drives the baking beef to continuously rotate and adjust the heating position, ensuring that the various parts of the beef are heated evenly, avoiding local overheating or insufficient heating, thereby improving the baking quality and consistency of taste. Moreover, the continuous rotation and adjustment of the heating position can make full use of the heat, reduce the baking time, improve the production efficiency, and improve the flexibility of the device.

[0025] In the present invention, a limit plate is provided, and in the process of the rotating seat being driven to rotate by the meshing of the rack and the gear, the rectangular plate connected to the lower end of the rotating seat will rotate with the rotating seat, and will fit with the rubber pad connected in the limit plate during the fourth rotation or reset. The rubber pad connected in the limit plate is made of rubber material, which provides a certain degree of elasticity, reduces the bumps and wear caused by the rectangular plate and its surface, and physically limits the rotating seat through the limit plate and the rubber pad to avoid failures or abnormal operations caused by excessive rotation of the rotating seat, thereby ensuring stable operation and more reliable control.

[0026] In the present invention, a collection box is provided. During the baking and heating process, a large amount of grease will be generated on the beef. The grease will fall into the collection box at the bottom along the smooth surface of the placement plate for collection. The collection box includes a transparent observation plate and a stepped scale bar. The staff can understand the amount of the collection box by observing the scale bar and perform cleaning work in time. The collection box is provided to prevent grease from dripping and adhering to the inner wall of the baking oven body, causing difficulty in cleaning, and to prevent grease from accumulating on the inner wall of the baking oven body, thereby reducing the obstruction of heat transfer, avoiding the breeding of bacteria, reducing the difficulty and workload of cleaning, and maintaining the hygiene of the equipment.

[0027] In the present invention, a push rod is provided, and after the baking process is completed, the rotating seat rotates to return to the initial position, and the box door is screwed to be in an open state. At this time, the control box controls the motor output shaft to rotate, and the motor output shaft drives two synchronous wheels to rotate. The two synchronous wheels drive the synchronous wheels connected to the outside of the two threaded rods to rotate through two synchronous belts, and the two threaded rods are driven to rotate through the connection between the synchronous wheels and the synchronous belts. The rotation of the two threaded rods drives the slider to slide on the bottom plate, and the push rod is driven to slide through the slider. The placement position of the push rod is in contact with the connecting block connected to the outside of the storage plate, and the storage plate is pushed out outward by the push rod and the connecting block, so as to increase the picking operation space, improve the convenience of the picking and unloading operation, make the entire unloading process faster and more efficient, and help to improve the overall efficiency of the production process.

[0028] In the present invention, a rectangular limit block is provided, and after a period of use, the collection box needs to be pulled out to pour out the accumulated grease inside for cleaning. When the collection box after cleaning is stuffed into the baking rack, the baking rack slides to fit the inclined smooth surface of the rectangular limit block, and pushes it toward one end close to the L-shaped base. At this time, the rectangular limit block squeezes the spring to contract, and when the collection box slides to the same horizontal position as the slot and the rectangular limit block, the rectangular limit block is pushed to slide and reset under the action of the spring and is connected to the slot. When the rectangular limit block is connected to the slot, its metal surface will make a sound when it fits and bumps, reminding the staff that the collection box is in a stable installation position. The collection box is clamped and limited by the rectangular limit blocks connected on both sides, so as to ensure the stability of the collection box placement position, so that the grease generated during the baking process can be accurately dripped into the collection box for collection and storage.

DETAILED DESCRIPTION

[0041] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0042] See also Figure 1-Figure 11The present invention provides an automatic temperature-adjusting beef jerky baking oven, comprising a baking oven body 11, a bottom plate 12 is fixedly connected inside the baking oven body 11, a cylinder 13 is fixedly connected to the upper end of the bottom plate 12, a rack 14 is sleeved on the outer surface of the cylinder 13, the rack 14 is slidably connected to the upper end of the bottom plate 12, a rotating seat 15 is rotatably connected inside the bottom plate 12, a gear 16 is sleeved on the outer surface of the rotating seat 15, the gear 16 and the rack 14 are meshed, a baking rack 17 is fixedly connected to the upper end of the rotating seat 15, a rectangular plate 18 is fixedly connected to the lower end of the rotating seat 15, a limiting plate 19 is fixedly connected to the upper end of the bottom plate 12, and a limiting plate 19 is fixedly connected to the upper end of the bottom plate 12. Two rubber pads 21 are sleeved inside the positioning plate 19, and the two rubber pads 21 are on the same horizontal line as the rectangular plate 18. A heating mechanism is fixedly connected to the inner wall of the baking oven body 11, and the heating mechanism includes a group of heating tubes 22, and a group of heating tubes 22 are fixedly connected to the inner wall of the baking oven body 11. A box door 23 is rotatably connected inside the baking oven body 11, and a control box 24 is fixedly connected to the side of the baking oven body 11 close to the box door 23. During the baking and heating process, the output shaft of the cylinder 13 is controlled to extend through the control box 24, and the stroke of the output shaft of the cylinder 13 is divided into four sections. The output shaft of the cylinder 13 extends to drive the rack 14 The upper end of the bottom plate 12 slides (the cylinder 13 and the rack 14 are connected by a connecting rod). During the sliding process of the rack 14, the meshing gear 16 drives the baking rack 17 connected to the rotating seat 15 to rotate. By controlling the extension distance of the cylinder 13, the baking rack 17 is driven to rotate 90 degrees at each start. After four starts, the baking rack 17 is driven to rotate nearly one circle (due to the volume of the limit plate 19 itself, the rotating seat 15 will be limited to less than one circle). At this time, the controller in the control box 24 controls the output shaft of the cylinder 13 to start intermittent contraction. The extension and contraction of the output shaft of the cylinder 13 drives the roasting beef to rotate continuously. In the heated position, when the rack 14 and the gear 16 are meshed to drive the rotating seat 15 to rotate, the rectangular plate 18 connected to the lower end of the rotating seat 15 will rotate with the rotating seat 15, and when it rotates four times or resets, it will fit with the rubber pad 21 connected to the limiting plate 19. The rubber pad 21 connected to the limiting plate 19 is made of rubber material, which provides a certain degree of elasticity and reduces the bumps and wear caused by the fitting of the rectangular plate 18 and its surface. The rotating seat 15 is physically limited by the limiting plate 19 and the rubber pad 21 to avoid failures or abnormal operations caused by excessive rotation of the rotating seat 15, thereby ensuring stable operation and more reliable control.

[0043] A group of storage plates 25 are slidably connected inside the baking rack 17, and a group of collection boxes 26 are slidably connected inside the baking rack 17. The group of collection boxes 26 are respectively located at the lower ends of the group of storage plates 25. The outer surfaces of the group of storage plates 25 and the group of collection boxes 26 are fixedly connected with handles 27. Both sides of the group of storage plates 25 are fixedly connected with connecting blocks 28. A group of collection boxes 26 are provided with card slots 29 inside. The upper end of the rotating seat 15 close to the baking rack 17 is fixedly connected with a motor 31. The upper end of the rotating seat 15 is slidably connected with a slider 32. The slider 32 is internally threaded with two threaded rods 33. The motor 31 and the two threaded rods The outer surfaces of the two sets of synchronous wheels 33 are sleeved with synchronous wheels 34, and the outer surfaces of the two sets of synchronous wheels 34 are sleeved with synchronous belts 35. The upper end of the slider 32 is fixedly connected with two push rods 36, and the two push rods 36 are respectively fitted with the two sets of connecting blocks 28. The outer surface of the baking rack 17 is sleeved with a heat insulation board 41, and the heat insulation board 41 is located at the upper end of the motor 31. The two push rods 36 are slidably connected to the inside of the heat insulation board 41. The processed marinated beef products are placed on the placement board 25. After the placement is completed, the handle 27 is held to slide the placement board 25 into the baking rack 17. The baking rack 17 is slidably connected with a collection box 26, and the collection box 26 is placed at the placement position. At the lower end of the plate 25, after the beef product is completely placed and stabilized, the oven door 23 is screwed to make the oven body 11 sealed and closed, and the start button on the oven door 23 is pressed. At this time, the heating tube 22 installed in the oven body 11 starts to heat and dry. The heating tube 22 is usually composed of a metal shell, a resistance wire, an insulating filling material, and a lead electrode. When current passes through the resistance wire, the resistance wire has a certain resistance, and the electrical energy is converted into thermal energy. The resistance wire generates heat, and the insulating filling material plays the role of insulation and heat conduction, and the heat generated by the resistance wire is evenly transferred to the metal shell and dissipated to the surrounding environment to dry the beef. The moisture carried in the product is processed into beef jerky. A control box 24 is connected to one side of the baking oven body 11. The control box 24 is connected to the heating tube 22, the box door 23, the cylinder 13, and the motor 31 and controls them. The control box 24 includes power protection components (such as air switches, fuses, relays, thermal relays, etc. to protect the internal circuits of the equipment) and a programmable logic controller (PLC). The control box 24 can be equipped with corresponding operation buttons. Users can input temperature setting values, heating or cooling rates, and holding time and other parameters at different stages through these operation interfaces, thereby forming a desired temperature curve.The control module in the control box 24 will control the automatic temperature adjustment of the heating tube 22 according to these set values ​​and parameters, and realize the effect of automatically adjusting the heating temperature when facing beef products with different water contents. During the baking and heating process, the beef will produce a large amount of grease, and the grease will fall into the collection box 26 at the bottom along the smooth surface of the storage plate 25 for collection. The collection box 26 includes a transparent observation plate (the transparent observation plate is quartz glass, which has very high heat resistance and can withstand high temperature environment) and a stepped scale bar. The staff can understand the content of the collection box 26 by observing the scale bar and clean it in time. The collection box 26 is set to prevent grease from dripping and adhering to the main body of the baking oven. The inner wall of 11 is difficult to clean, which prevents grease from accumulating on the inner wall of the baking oven main body 11, reduces the obstruction of heat transfer, avoids the breeding of bacteria, reduces the difficulty and workload of cleaning, and keeps the equipment hygienic. The heat insulation board 41 arranged in the baking oven main body 11 is above the cylinder 13 and the motor 31. The heat insulation board 41 is made of ceramic fiber material and has excellent heat insulation performance, which can effectively block heat transfer. The cylinder 13 and the motor 31 are shielded and protected by the heat insulation board 41 to avoid affecting their performance due to the high temperature environment. After the beef jerky is processed, screw open the box door 23, hold the handle 27 to pull out the storage plate 25 for subsequent packaging.

[0044] The outer surface of the baking rack 17 is fixedly connected with two groups of L-shaped bases 37, the inner surfaces of the two groups of L-shaped bases 37 are sleeved with springs 38, the outer surfaces of the two groups of springs 38 are fixedly connected with rectangular limit blocks 39, the two groups of rectangular limit blocks 39 are respectively slidably connected to the inside of the two groups of L-shaped bases 37, and the two groups of rectangular limit blocks 39 are respectively clamped in the inside of the two groups of card slots 29. After the baking process is completed, the rotating seat 15 rotates to restore to the initial position, and the box door 23 is screwed to open it. At this time, the control box 24 controls the output shaft of the motor 31 The output shaft of the motor 31 drives the two synchronous wheels 34 to rotate, and the two synchronous wheels 34 drive the synchronous wheels 34 connected to the two threaded rods 33 to rotate through the two synchronous belts 35. The two threaded rods 33 are driven to rotate by the connection between the synchronous wheels 34 and the synchronous belts 35. The rotation of the two threaded rods 33 drives the slider 32 to slide on the bottom plate 12, and the slider 32 drives the push rod 36 to slide. The placement position of the push rod 36 is in contact with the connecting block 28 connected to the outside of the storage plate 25. The push rod 36 and the connecting block 28 are in contact with each other. The storage plate 25 is pushed outward to slide out to increase the space for taking out and operation, and improve the convenience of taking out and unloading. After a period of use, the collection box 26 needs to be pulled out to pour out the accumulated grease inside for cleaning. When the collection box 26 after cleaning is inserted into the baking rack 17, the baking rack 17 slides to fit the inclined and smooth surface of the rectangular limit block 39, and pushes it to the end close to the L-shaped base 37. At this time, the rectangular limit block 39 squeezes the spring 38 to contract. When the collection box 26 slides to the slot 29 and the rectangular limit block When 39 are in the same horizontal position, the rectangular limit block 39 is pushed to slide and reset under the action of the spring 38 and is engaged in the card slot 29. When the rectangular limit block 39 is engaged in the card slot 29, its metal surface will make a sound when it collides with the card slot 29, reminding the staff that the collection box 26 is in a stable installation position. The collection box 26 is engaged and limited by the rectangular limit blocks 39 connected on both sides to ensure the stability of the placement of the collection box 26, so that the grease generated during the baking process can be accurately dripped into the collection box 26 for collection and storage.

[0045] Working principle:

[0046] The first step is to place the processed and marinated beef products on the placement plate 25. After placement, hold the handle 27 to slide the placement plate 25 into the baking rack 17. The baking rack 17 is slidably connected with a collection box 26. The collection box 26 is placed at the lower end of the placement plate 25. After the beef products are completely placed and stabilized, screw the box door 23 to make the baking oven body 11 in a sealed and closed state, press the start button on the box door 23, and then the heating tube 22 installed in the baking oven body 11 starts to heat and dry. The heating tube 22 is usually composed of a metal shell, a resistance wire, an insulating filling material, and a lead electrode. When current passes through the resistance wire, the resistance wire has a certain resistance, and the electrical energy is converted into heat energy. The resistance wire heats up, and the insulating filling material plays an insulating role. Through the effects of insulation and heat conduction, the heat generated by the resistance wire is evenly transferred to the metal shell and dissipated into the surrounding environment, drying the moisture carried by the beef product to make it into beef jerky. A control box 24 is connected to one side of the baking oven body 11. The control box 24 is connected to the heating tube 22, the box door 23, the cylinder 13, and the motor 31 and controls them. The control box 24 includes power protection components (such as air switches, fuses, relays, thermal relays, etc. to protect the internal circuits of the equipment) and a programmable logic controller (PLC). The control box 24 can be equipped with corresponding operation buttons. Users can use these operation interfaces to input parameters such as temperature setting values, heating or cooling rates, and holding time at different stages to form a desired temperature curve. The control module in the control box 24 will control the automatic temperature adjustment of the heating tube 22 according to these set values ​​and parameters, and realize the effect of automatically adjusting the heating temperature when facing beef products with different water contents. During the baking and heating process, the beef will produce a large amount of grease, and the grease will fall into the collection box 26 at the bottom along the smooth surface of the storage plate 25 for collection. The collection box 26 includes a transparent observation plate (the transparent observation plate is quartz glass, which has very high heat resistance and can withstand high temperature environment) and a stepped scale bar. The staff can understand the content of the collection box 26 by observing the scale bar and clean it in time. The collection box 26 is set to prevent grease from dripping and adhering to the main body of the baking oven. The inner wall of 11 is difficult to clean, which prevents grease from accumulating on the inner wall of the baking oven main body 11, reduces the obstruction of heat transfer, avoids the breeding of bacteria, reduces the difficulty and workload of cleaning, and keeps the equipment hygienic. The heat insulation board 41 arranged in the baking oven main body 11 is above the cylinder 13 and the motor 31. The heat insulation board 41 is made of ceramic fiber material and has excellent heat insulation performance, which can effectively block heat transfer. The cylinder 13 and the motor 31 are shielded and protected by the heat insulation board 41 to avoid affecting their performance due to the high temperature environment. After the beef jerky is processed, screw open the box door 23, hold the handle 27 to pull out the storage plate 25 for subsequent packaging.

[0047] In the second step, during the baking and heating process, the output shaft of the cylinder 13 is controlled to extend through the control box 24, and the stroke of the output shaft of the cylinder 13 is divided into four sections. The output shaft of the cylinder 13 extends to drive the rack 14 to slide on the upper end of the bottom plate 12 (the cylinder 13 and the rack 14 are connected by a connecting rod). During the sliding process of the rack 14, the meshing gear 16 drives the baking rack 17 connected to the rotating seat 15 to rotate. By controlling the extension distance of the cylinder 13, the baking rack 17 is driven to rotate ninety degrees at each start. After four starts, the baking rack 17 is driven to rotate nearly one circle (due to the volume of the limit plate 19 itself, the rotating seat 15 will be limited to less than one circle). At this time, the controller in the control box 24 controls the output shaft of the cylinder 13 to start intermittent Contraction, the output shaft of the cylinder 13 extends and contracts to drive the roasting beef to rotate continuously to adjust the heating position. When the rack 14 and the gear 16 are engaged to drive the rotating seat 15 to rotate, the rectangular plate 18 connected to the lower end of the rotating seat 15 will rotate with the rotating seat 15, and when it rotates four times or resets, it will fit with the rubber pad 21 connected to the limit plate 19. The rubber pad 21 connected to the limit plate 19 is made of rubber material, which provides a certain degree of elasticity and reduces the bumps and wear caused by the rectangular plate 18 and its surface. The rotating seat 15 is physically limited by the limit plate 19 and the rubber pad 21 to avoid failures or abnormal operations caused by excessive rotation of the rotating seat 15, thereby ensuring stable operation and more reliable control.

[0048] In the third step, after the baking process is completed, the rotating seat 15 rotates to restore to the initial position, and the box door 23 is screwed to open it. At this time, the control box 24 controls the output shaft of the motor 31 to rotate, and the output shaft of the motor 31 drives the two synchronous wheels 34 to rotate. The two synchronous wheels 34 drive the synchronous wheels 34 connected to the outside of the two threaded rods 33 to rotate through the two synchronous belts 35. The two threaded rods 33 are driven to rotate by the connection between the synchronous wheels 34 and the synchronous belts 35. The rotation of the two threaded rods 33 drives the slider 32 to slide on the bottom plate 12, and the slider 32 drives the push rod 36 to slide. The placement position of the push rod 36 is in contact with the connecting block 28 connected to the outside of the storage plate 25. The storage plate 25 is pushed outward by the push rod 36 and the connecting block 28 to increase the taking operation space and improve the convenience of taking and unloading operations. After a period of use, the collection box 26 needs to be pulled out. The grease accumulated inside is poured out for cleaning. When the collection box 26 after cleaning is stuffed into the baking rack 17, the baking rack 17 slides to fit the inclined smooth surface of the rectangular limit block 39, pushing it to one end close to the L-shaped base 37. At this time, the rectangular limit block 39 squeezes the spring 38 to shrink. When the collection box 26 slides to the position where the slot 29 and the rectangular limit block 39 are at the same horizontal line, the rectangular limit block 39 is pushed to slide and reset under the action of the spring 38 to be connected in the slot 29. When the rectangular limit block 39 is connected in the slot 29, its metal surface will make a sound when it is connected and bumped, reminding the staff that the collection box 26 is in a stable installation position. The collection box 26 is clamped and limited by the rectangular limit blocks 39 connected on both sides to ensure the stability of the collection box 26 placement position, so that the grease generated during the baking process can be accurately dripped into the collection box 26 for collection and storage.
