Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of drying device, specifically a kind of beef jerky drying device, belong to beef processing equipment technical field. BACKGROUND

[0002] As a traditional meat product, beef jerky is popular in domestic and foreign markets due to its rich nutritional value, unique flavor and portability. Its processing process mainly includes cutting, curing, drying and seasoning, among which the drying step is particularly critical, directly affecting the taste, color, shelf life and overall quality of the product. Traditional beef jerky drying methods mostly use natural airing or earth oven baking. Although these methods are simple and easy to implement, they are greatly affected by weather conditions and hygiene conditions are difficult to guarantee, and production efficiency is low, which cannot meet the needs of modern industrial production. With the development of food processing technology, mechanical drying methods such as hot air drying, vacuum freezing drying and infrared drying have gradually replaced traditional methods. Hot air drying devices are widely used in beef jerky processing due to their relatively simple structure, low cost and large production capacity. However, existing hot air drying equipment still has many technical bottlenecks, such as uneven drying, high energy consumption and single function, which restrict the high-quality development of the beef jerky industry.

[0003] In the prior art, for example, a semi-dry type beef drying processing device disclosed in publication number CN215113620U includes a drying chamber, a hot air circulation system and an inclined material rack, aiming to allow both sides of beef slices to receive hot air impact. However, the material rack of this device is of fixed structure, and beef slices are relatively static during drying, relying only on the flow of hot air to achieve heat exchange and water evaporation, which can easily lead to drying dead angles, especially when the material is densely stacked, hot air is difficult to penetrate all the material, causing uneven drying, and local high moisture may cause deterioration. In addition, the hot air circulation system of this device is relatively simple, and the humid exhaust gas is not effectively dehumidified and reused, resulting in high energy consumption, and lacking effective dust removal or auxiliary heating means, with single function; for example, a beef jerky drying box with dust removal function disclosed in publication number CN219531404U has a dust removal mechanism inside the box, which removes impurities on the surface of beef jerky through the dust removal boxes on both sides (one side blows air, and the other side sucks air). This design solves the hygiene problem to some extent, but the dust removal process and the drying process are independent of each other, and even may interfere with each other. When blowing dust, the introduction of cold air will lower the temperature inside the drying box, disrupt the thermal balance and increase energy consumption; on the other hand, the efficiency of the hot air recovery system of this equipment is not high, and the moisture and residual heat in the exhaust gas cannot be fully utilized, also having the problem of high energy consumption. In addition, the material suspension system of this device is relatively simple and cannot achieve dynamic movement of the material, with limited improvement in drying uniformity. SUMMARY

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model is equipped with a drying tank, a suspended rotating assembly, a bent air duct, a hot air circulation pipe, an adsorption drying tower, and an infrared radiation plate. Multiple sets of bent air ducts can introduce the drying hot air provided by the hot air circulation pipe into the tank at multiple angles and directions, and can arrange the air jets at different spatial positions. In coordination with the movement of the suspended rotating assembly, a dynamic and turbulent airflow field covering the entire cross-section of the tank is formed, so that the hot air can fully contact the surface of the beef, improving the drying efficiency of the beef. The hot air circulation pipe on the outside and the adsorption drying tower connected to it together constitute an energy-saving system, realizing the recycling and reuse of waste heat air. The infrared radiation plate connected to the bottom of the tank provides radiant heating, which can perform penetrating heating of the beef from the inside out, complementing the hot air convection heating, and further shortening the drying time.

[0018] 2. The suspension rotation assembly of this utility model includes a revolution shaft, a rotation rod, and a mesh suspension plate. Multiple layered mesh suspension plates are fixedly connected to the body of the rotation rod, with the diameter of the mesh suspension plates decreasing from top to bottom. While the revolution shaft drives the multiple rotation rods to rotate, each rotation rod rotates synchronously. The revolution shaft is responsible for achieving the overall revolution, while the cross-shaped distribution design of the rotation rods ensures structural stability and a large suspension space. Furthermore, while the revolution shaft drives the rotation rods to revolve, each rotation rod can also rotate synchronously, allowing each piece of beef suspended on the mesh suspension plate to be rotated simultaneously. The rotation and revolution of the sun completely eliminate the drying dead zones, allowing the beef surface to receive hot air and radiation without any blind spots. This greatly improves the uniformity and efficiency of drying, avoiding problems such as uneven drying and local deterioration caused by static suspension or single movement in traditional equipment. The mesh hanging tray adopts a layered design with the diameter decreasing from top to bottom, which adapts to the thermal field distribution in the drying tank. As hot air rises, the temperature at the top is usually slightly higher. By increasing the upper layer hanging density and decreasing the lower layer hanging density, the drying rate of each layer of material is balanced. The mesh structure not only ensures the installation of hooks but also minimizes the obstruction of airflow.

The coarse adsorption layer, fine adsorption layer, and buffer adsorption layer in the adsorption drying tower play a role in staged deep dehumidification, which can efficiently remove moisture from the circulating air. The desiccant regeneration unit realizes the recycling of the adsorbent. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] like Figures 1 to 10As shown, a beef jerky drying device includes a drying tank 1, a suspended rotating assembly 8 movably installed inside the drying tank 1, multiple sets of bent ventilation pipes 22 fixedly connected to the inner wall of the drying tank 1, a hot air circulation pipe 2 installed on the outer side of the drying tank 1, the air outlet of the hot air circulation pipe 2 connected to the bent ventilation pipes 22, an adsorption drying tower 3 connected to the pipe body of the hot air circulation pipe 2, and an infrared radiation plate 9 connected to the bottom surface of the drying tank 1. The multiple sets of bent ventilation pipes 22 can introduce the drying hot air provided by the hot air circulation pipe 2 into the tank at multiple angles and directions. The jet nozzles 23 can be arranged in different spatial positions to coordinate with the movement of the suspended rotating component 8, forming a dynamic, turbulent airflow field that covers the entire cross-section of the tank, allowing the hot air to fully contact the surface of the beef and improving the drying efficiency of the beef. The outer hot air circulation pipe 2 and its connected adsorption drying tower 3 together constitute an energy-saving system, realizing the recovery and reuse of waste heat air. The infrared radiation plate 9 connected to the bottom of the tank provides radiant heating, which can perform penetrating heating of the beef from the inside out, complementing the hot air convection heating and further shortening the drying time.

[0034] The suspension rotation assembly 8 includes a revolution shaft 82, rotation rods 87, and mesh suspension discs 84. The rotation rods 87 are connected to the outer periphery of the revolution shaft 82 in a cross-shaped arrangement. Multiple layered mesh suspension discs 84 are fixedly connected to the rods of the rotation rods 87, with the diameter of the mesh suspension discs 84 decreasing from top to bottom. While the revolution shaft 82 drives the multiple rotation rods 87 to rotate, each rotation rod 87 rotates synchronously. The revolution shaft 82 is responsible for achieving the overall revolution, while the cross-shaped distribution design of the rotation rods 87 ensures the stability of the structure and a large suspension space. Furthermore, while the revolution shaft 82 drives the rotation rods 87 to revolve, each rotation rod 87 can also rotate synchronously, allowing the suspension to maintain its position within the mesh suspension. Each piece of beef on the perforated hanging disc 84 can simultaneously revolve and rotate, thus completely eliminating drying dead zones and enabling the beef surface to receive hot air and radiation 360 degrees without blind spots. This greatly improves the uniformity and efficiency of drying and avoids problems such as uneven drying and local deterioration caused by static suspension or single movement in traditional equipment. The perforated hanging disc 84 adopts a layered design with the diameter decreasing from top to bottom, which adapts to the thermal field distribution in the drying tank 1. As hot air rises, the temperature at the top is usually slightly higher. By increasing the upper layer suspension density and decreasing the lower layer suspension density, the drying rate of each layer of material is balanced. Moreover, the perforated structure not only ensures the installation of the hook 89 but also minimizes its obstruction of airflow.

[0035] The adsorption drying tower 3 includes a tower shell 31. Inside the tower shell 31, along the airflow direction, a coarse adsorption layer 34, a fine adsorption layer 33, and a buffer adsorption layer 32 are sequentially arranged. A desiccant regeneration unit is connected to the hot air circulation pipe 2 at the upper and lower ends of the adsorption drying tower 3. The coarse adsorption layer 34, fine adsorption layer 33, and buffer adsorption layer 32 in the adsorption drying tower 3 play a role in staged deep dehumidification, which can efficiently remove moisture from the circulating air. The desiccant regeneration unit realizes the recycling of the adsorbent. It should be noted that the coarse adsorption layer 34 can use silica gel with high adsorption capacity and high mechanical strength as the adsorbent, which can efficiently capture a large amount of moisture, bear the main dehumidification load, and reduce the burden on subsequent layers. The fine adsorption layer 33 can use 3A or 4A molecular sieve with low dew point and high precision as the adsorbent for deep drying, which reduces the dew point of the gas to an extremely low level and ensures the dryness of the outlet. The buffer adsorption layer 32 can use high-strength and wear-resistant silica gel as the adsorbent to prevent powder from flying.

[0036] Example 2

[0037] Improvements based on Example 1:

[0038] like Figure 1 and Figure 2 As shown, a sealing door 11 is movably connected to the tank wall of the drying tank 1. A sealing strip 13 is embedded in the opening of the tank wall where the sealing door 11 is connected. A support foot 12 is connected to the bottom of the drying tank 1. The sealing door 11 is movably connected to the tank wall to provide a manual operation interface, which is convenient for hanging beef materials and cleaning and maintaining the inside of the equipment. The sealing strip 13 can ensure that when the sealing door 11 is closed, it forms a tight seal with the tank body, effectively preventing the leakage of high temperature and high humidity air inside the tank. The support foot 12 connected to the bottom of the drying tank 1 can provide physical support and stability to prevent shaking or tilting during operation.

[0039] like Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the air inlet of the hot air circulation pipe 2 is connected to a gas collection hood 21, which is connected to the upper end of the drying tank 1. The pipe body of the hot air circulation pipe 2 is also connected to a circulation pump 4 and a PTC heater 5. The connection position of the PTC heater 5 is close to the air outlet of the hot air circulation pipe 2. The gas collection hood 21 effectively collects the gas discharged from the top of the drying tank 1, maximizing the waste gas recovery efficiency. The circulation pump 4 provides power for the entire circulating air system. The PTC heater 5 heats the air before it enters the drying tank 1, precisely heating the dry air that has been dehumidified by the adsorption drying tower 3, and can immediately heat the air with the optimal moisture content to the target process temperature.

[0040] Furthermore, multiple sets of bent vent pipes 22 cover half of the inner wall of the drying tank 1. The body of the bent vent pipes 22 is provided with several air jet holes 23. When the suspended beef rotates with the revolution axis 82, the suspended beef will periodically enter the half covered by the bent vent pipes 22 and the other half, avoiding the airflow from colliding and canceling each other out in the whole tank, reducing energy loss. At the same time, it allows the front and back sides and different parts of the beef slices to be alternately subjected to the direct impact of high-speed airflow and the slow evaporation of the relatively static area, thereby improving the drying quality and uniformity. The air jet holes 23 can guide the airflow toward the rotating material and accelerate the evaporation of moisture. It should be noted that the opening angle of the air jet holes 23 is designed to be inclined after being optimized by fluid dynamics, so that the sprayed airflow can flow along the inner wall of the drying tank 1, thereby ensuring that the airflow covers all areas inside the tank, completely eliminating drying dead corners, improving drying uniformity, and solving the problem of uneven heat field inside the tank.

[0041] like Figures 1 to 4 As shown, the desiccant regeneration unit includes an inlet pipe 6 and an exhaust pipe 7. The inlet pipe 6 is connected to the body of the hot air circulation pipe 2 at the lower end of the adsorption drying tower 3, and the exhaust pipe 7 is connected to the body of the hot air circulation pipe 2 at the upper end of the adsorption drying tower 3. The other end of the inlet pipe 6 is connected to an external air intake system. When regeneration is required, a portion of externally introduced hot air can be introduced into the bottom of the adsorption drying tower 3. The external hot drying air enters from the bottom of the tower, passes through the adsorption drying tower 3 in a reverse direction, desorbs the moisture captured in the pores of the adsorbent, and is carried out by the airflow through the exhaust pipe 7. This allows the adsorption drying tower 3 to operate continuously without frequent replacement of expensive adsorbent materials. It should be noted that the external air intake system can adopt the external air intake (on the side wall of the chassis), internal air intake (connecting to the inside of the chassis), cover plate + slide groove + drive mechanism (adjusting the opening of the internal air intake) involved in the air filter air intake device disclosed in CN222296462U. The air filter outlet is connected to the air compressor inlet through the air inlet pipe. The air filter box is provided with an internal air intake, which connects the inside of the chassis and the air filter channel. Slide grooves are provided on both sides of the internal air intake, and a cover plate is slidably installed in the slide grooves. The air filter box is provided with a drive mechanism, which drives the cover plate to move in the slide grooves to control the position of the cover plate covering the internal air intake. A temperature sensor is provided in the air filter channel. This invention uses a temperature sensor to detect the air temperature in the air filter channel in real time, feeds it back to the host and controls the drive mechanism to work, thereby controlling the cover to move along the slide groove, thus adjusting the opening and closing of the inner air inlet, and thus controlling the amount of hot air flowing into the air filter channel from the chassis, so as to control the air temperature in the air filter channel and provide dry and clean hot air.

[0042] Furthermore, an intake three-way valve 61 is connected between the intake pipe 6 and the hot air circulation pipe 2, and an exhaust three-way valve 71 is connected between the exhaust pipe 7 and the hot air circulation pipe 2. Both the intake three-way valve 61 and the exhaust three-way valve 71 are connected to an external control terminal via signal connection. The intake three-way valve 61 and the exhaust three-way valve 71 are used to switch between the two working modes of drying cycle and desiccant regeneration cycle.

[0043] like Figure 3 , Figure 5 , Figure 9 and Figure 10 As shown, the suspended rotating assembly 8 also includes a rotating motor 81, which is fixedly connected to the bottom of the drying tank 1. The rotating shaft of the rotating motor 81 is fixedly connected to the revolution shaft 82 along the same axis. Placing the rotating motor 81 at the bottom of the tank allows the power output to act directly on the lower end of the revolution shaft 82, improving transmission efficiency and reliability. At the same time, it also lowers the overall center of gravity of the equipment and enhances stability.

[0044] Furthermore, multiple sets of cross struts 83 are fixedly connected to the shaft of the revolution shaft 82. Bearings 88 are fixedly connected to the ends of the cross struts 83. The shaft of the rotating rod 87 is fixedly sleeved in the inner ring of the bearing 88. A rotating gear 86 is coaxially fixedly sleeved at the top of the rotating rod 87. An internal gear ring 85 is fixedly connected to the inner side of the top of the drying tank 1. Multiple rotating gears 86 mesh with the internal gear ring 85. The multiple sets of cross struts 83 fixedly connected to the shaft of the revolution shaft 82 serve to support and connect the frame. The bearing 88 allows the rotating rod 87 to rotate freely relative to the cross struts 83 when the shaft is fixedly sleeved in its inner ring. The rotating gear 86 and the internal gear ring 85 form a planetary gear system. When the rotating motor 81 drives the revolution shaft 82 to rotate, the cross strut 83 revolves accordingly, causing its end-end rotating rod 87 to revolve as well. Since the rotating gear 86 meshes with the fixed internal gear ring 85, the revolution forces the rotating gear 86 to roll along the gear ring of the internal gear ring 85, thus generating rotation, driving the rotating rod 87 to rotate around its own axis. It should be noted that the shaft of the revolution shaft 82 and the cross strut 83 are detachably fixed together by screws. By using a detachable connection for the cross strut 83, during assembly and maintenance, the sealing door 11 can be opened to install or remove the rotating rods 87 one by one. Therefore, it is convenient to remove a single rotating rod 87 for individual installation. Multiple mesh suspension discs 84 are assembled on the same rotating rod 87 without the need for complete disassembly of the suspension rotating assembly 8. This design optimizes the operating space, facilitates daily maintenance and cleaning, and solves the problem of inconvenience caused by the need to install or remove the suspension rotating assembly 8 from the bottom due to limited operating space. Both the rotating gear 86 and the internal gear ring 85 are made of food-grade stainless steel, which has high temperature resistance, corrosion resistance, and self-lubricating properties. The rotating gear 86 and the internal gear ring 85 are regularly cleaned and maintained. By using specific materials to prepare the rotating gear 86 and the internal gear ring 85, the high temperature resistance, corrosion resistance, and self-lubricating properties of the materials themselves can meet the requirements of drying rings in high temperature, high humidity, and possibly containing grease and meat scraps. In this environment, the grease will not solidify due to the high temperature. The grease adhering to the rotating gear 86 and the internal gear ring 85 will have a certain lubricating effect, which is beneficial to the rotation of the rotating gear 86. Even if there are some meat scraps mixed in the grease, they can be crushed and pulverized during the meshing action and fall off under the lubrication of the grease. This prevents the meat scraps from sticking to the rotating gear 86 or the internal gear ring 85 during the drying process. Secondly, the rotating gear 86 and the internal gear ring 85 will be cleaned and maintained regularly. That is, they can be cleaned by high-pressure water rinsing after each use. This will wash away the meat scraps adhering to the rotating gear 86 or the internal gear ring 85, thereby reducing wear and the risk of jamming.

[0045] Furthermore, the lower surface of the mesh hanging tray 84 is connected to multiple hooks 89, which are evenly distributed in a ring along the edge of the mesh hanging tray 84. The beef material is suspended by the hooks 89, so that the entire surface of the beef slices is exposed to the circulating hot air and infrared radiation as much as possible, avoiding the drying dead corners caused by contact with the tray. The multiple hooks 89 work together to ensure that the suspended beef slices are evenly distributed around the rotating rod 87, and to prevent the material from accumulating in the center area of ​​the tray. This ensures that the airflow can smoothly pass through the gaps between the mesh of the mesh hanging tray 84 and the material from multiple directions, eliminating ventilation dead corners.

[0046] Working principle: The operator first opens the sealing door 11 and hangs the beef on the hook 89 on the lower plate of the mesh hanging plate 84. Then, the sealing door 11 is closed and the sealing strip 13 is used to ensure the airtightness of the drying tank 1. After the equipment is started, the rotating motor 81 starts to work. Its rotating shaft drives the revolution shaft 82 to rotate. The revolution shaft 82 drives multiple sets of cross struts 83 fixedly connected to its shaft to revolve. The bearing 88 at the end of the cross strut 83 drives the self-rotating rod 87 to revolve together. At the same time, since the rotating gear 86 at the top of the self-rotating rod 87 meshes with the internal gear ring 85 fixed to the inner side of the top of the drying tank 1, the revolution motion forces the rotating gear 86 to roll along the internal gear ring 85, thereby driving each self-rotating rod 87 to rotate synchronously around its own axis. This makes the suspended beef undergo both revolution and self-rotation motion at the same time.

[0047] During operation, the circulation pump 4 provides power to draw the humid air from the top of the drying tank 1 into the hot air circulation pipe 2 through the air collection hood 21. The humid air first flows through the adsorption drying tower 3, where the coarse adsorption layer 34, fine adsorption layer 33, and buffer adsorption layer 32 are arranged in sequence to perform graded deep dehydration and drying. The dried air then flows through the PTC heater 5 and is precisely heated to the set temperature. Finally, the dried hot air is sent into multiple sets of bent ventilation pipes 22 through the outlet of the hot air circulation pipe 2, and is sprayed into the drying tank 1 from multiple angles and directions through the jet holes 23 on the pipe body. It fully contacts the rotating beef surface to form a dynamic turbulent airflow field to improve heat exchange efficiency. At the same time, the infrared radiation plate 9 set on the bottom of the drying tank 1 emits infrared rays to penetrate and heat the beef, forming a synergistic effect with the hot air convection heating to accelerate moisture evaporation.

[0048] When the adsorbent in the adsorption drying tower 3 needs to be regenerated, the control terminal operates the inlet three-way valve 61 and the exhaust three-way valve 71 to switch the passage, so that the externally introduced hot dry air enters from the bottom of the adsorption drying tower 3 through the inlet pipe 6 and penetrates the adsorbent bed in reverse. After desorption of moisture, the waste gas carrying moisture is discharged through the exhaust pipe 7, realizing the online regeneration and recovery of the adsorbent.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
