Description

Technical Field

[0001] This utility model relates to the field of yak jerky processing technology, specifically to a low-temperature drying device for processing yak jerky. Background Technology

[0002] In the processing of yak jerky, yak meat cut into strips needs to be dried at low temperatures for packaging and storage. A search revealed existing technology (publication number: CN202122094780.9) for a low-temperature vacuum drying device. The document describes a process where "a vacuum pump extracts air from the inside of the vacuum low-temperature drying chamber, creating a low-pressure vacuum, lowering the evaporation temperature, and making it easier for moisture to evaporate and dry. An electric heating wire heats and dries the surrounding drying tray, while a motor drives a rotating rod to rotate, and a stirring plate agitates the material to prevent uneven drying." However, in this existing technology, the heating wire is positioned at the bottom of the tray, resulting in the highest drying efficiency at the bottom of the material. When stirring the material in the tray, this can easily lead to insufficiently dried strips of jerky sticking together. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a low-temperature drying device for processing yak jerky is provided to solve the problem that in existing technologies, the heating wire is located at the bottom of the tray, where the drying degree is highest at the bottom of the material. When stirring the material in the tray, multiple pieces of jerky are prone to sticking together due to insufficient drying.

[0004] To achieve the above objectives, a low-temperature drying device for processing yak jerky is provided, comprising: a yak jerky dryer, wherein heat radiation devices are installed on the left and right side walls of the yak jerky dryer.

[0005] A vacuum pump is fixed to the upper end of the beef jerky dryer. Tilting discs are equidistantly arranged on the rear side wall of the beef jerky dryer. A limit rod is welded to the front end of the tilting disc. A storage mesh frame and a cover plate are inserted into the limit rod through a ring block. A perforated partition is welded to the inner side of the storage mesh frame. The rear end of the storage mesh frame is inserted into the tilting disc through a cross-shaped insert. A drive shaft is connected to the rear end of the tilting disc through a fixed shaft. A motor is connected to the rear end of the drive shaft. A first pulley assembly and a second pulley assembly are installed on the shaft surface of the drive shaft.

[0006] Furthermore, a sealing door is installed on the front end of the beef jerky dryer, and a glass window is provided on the surface of the sealing door. The right side of the sealing door is fixed to the beef jerky dryer by a latch.

[0007] Furthermore, a vacuum port is provided on the rear cavity wall of the beef jerky dryer, and the vacuum pump is connected to the vacuum port through a vacuum tube.

[0008] Furthermore, water collection boxes are symmetrically inserted into the lower cavity wall of the beef jerky dryer, and ring blocks are welded to the lower surface of the storage mesh frame and the upper surface of the cover plate.

[0009] Furthermore, a cover plate is hinged to the upper end face of the storage mesh frame, and the storage mesh frame and the cover plate are inserted and clamped at the distance between the limiting rods.

[0010] Furthermore, the front end face of the rotating disc is provided with a positioning groove; and the positioning groove is inserted into the cross-shaped insert block, and the fixed shaft sealing connection is located at the rear cavity wall of the beef jerky dryer.

[0011] Furthermore, a motor is installed on the rear surface of the beef jerky dryer, and the motor is connected to three sets of drive shafts through a first pulley assembly and a second pulley assembly.

[0012] The beneficial effects of this utility model are as follows: the low-temperature drying equipment for yak jerky processing utilizes multiple spaces within the storage mesh frame to individually store long strips of yak jerky. By inserting the closed storage mesh frame into the front of the turning plate, the pulley assembly on the surface of the motor-driven transmission shaft rotates, causing the storage mesh frames inserted into the upper and lower three-layer turning plates to rotate and flip over. This facilitates real-time turning of the yak jerky during low-temperature drying, enhances the uniformity of heating and drying, prevents the yak jerky from sticking to the mesh frame surface and becoming difficult to peel off, ensures the integrity of the yak jerky after low-temperature drying, and improves the production quality of the low-temperature drying equipment.

[0018] Reference Figures 1 to 4As shown, this utility model provides a low-temperature drying device for processing yak jerky, including: a jerky dryer 1, with heat radiation devices 4 installed on the left and right side walls of the jerky dryer 1.

[0019] A vacuum pump 2 is fixed on the upper end of the beef jerky dryer 1. Tilting discs 5 are equidistantly arranged on the rear side wall of the beef jerky dryer 1. A limit rod 51 is welded to the front end of the tilting disc 5. A storage mesh frame 3 and a cover plate 31 are inserted into the rod surface of the limit rod 51 through a ring block 34. A perforated partition plate 32 is welded to the inner side of the storage mesh frame 3. The rear end of the storage mesh frame 3 is inserted into the tilting disc 5 through a cross-shaped insert 33. A drive shaft 53 is connected to the rear end of the tilting disc 5 through a fixed shaft 52. A motor 54 is connected to the rear end of the drive shaft 53. A first pulley assembly 55 and a second pulley assembly 56 are installed on the shaft surface of the drive shaft 53.

[0020] First, place the yak jerky cut into long strips inside the storage mesh frame 3 and close the cover plate 31. Insert the storage mesh frame 3 into the front of the flip plate 5. After the storage mesh frame 3 is placed in multiple layers in the jerky dryer 1, close the sealing door 11. The vacuum pump 2 evacuates the cavity of the jerky dryer 1, creating a low-pressure vacuum that lowers the evaporation temperature, making it easier for the yak jerky to evaporate and dry. The heat radiation device 4 heats the yak jerky to a certain temperature for low-temperature drying, avoiding high-temperature damage to the texture. During the drying process, the electric... The machine starts on a timer, driving the central drive shaft 53 to rotate. This causes the first pulley assembly 55 and the second pulley assembly 56 on the surface of the drive shaft 53 to drive the three sets of drive shafts 53 to rotate synchronously. This causes the storage mesh frame 3 on the front side of the turning plate 5 to turn over, facilitating real-time turning of the yak jerky during low-temperature drying. This enhances the heat and drying uniformity of the yak jerky, prevents the yak jerky from sticking to the mesh frame surface and making it difficult to peel off, and ensures the integrity of the yak jerky after low-temperature drying. After drying is complete, remove the storage mesh frame 3 and pour out the yak jerky.

[0021] In this embodiment, a sealing door 11 is installed on the front end of the beef jerky dryer 1, and a glass window 12 is provided on the surface of the sealing door 11. The right side of the sealing door 11 is fixed to the beef jerky dryer 1 by a latch 13. A vacuum port 14 is opened on the rear cavity wall of the beef jerky dryer 1, and the vacuum pump 2 is connected to the vacuum port 14 through a vacuum tube 21. Water collection boxes 15 are symmetrically inserted into the lower cavity wall of the beef jerky dryer 1, and ring blocks 34 are welded to the lower surface of the storage mesh frame 3 and the upper surface of the cover plate 31.

[0022] As a preferred implementation, the sealing door 11 effectively prevents outside air from entering the beef jerky dryer 1, thus avoiding affecting the vacuum level inside the dryer 1. The vacuum pump 2 applies a vacuum to the dryer 1, causing the moisture in the yak jerky in the mesh frame 3 to sublimate directly from a solid to a gaseous state, thereby completing dehydration and drying without damaging the yak jerky's structure. The water collection box 15 collects condensed water droplets.

[0023] In this embodiment, a cover plate 31 is hinged to the upper end face of the storage mesh frame 3, and the storage mesh frame 3 and the cover plate 31 are inserted and clamped at the distance of the limiting rods 51. A positioning groove 57 is provided on the front end face of the flipping disk 5; and the positioning groove 57 is inserted into the cross-shaped insert block 33. The fixed shaft 52 is sealed and connected to the rear cavity wall of the beef jerky dryer 1. A motor 54 is installed on the rear surface of the beef jerky dryer 1, and the motor 54 is connected to three sets of drive shafts 53 through the first pulley assembly 55 and the second pulley assembly 56.

[0024] In a preferred embodiment, the storage mesh frame 3, the perforated partition 32, and the cover plate 31 allow the long strips of yak jerky to be dried and placed separately, preventing multiple strips from sticking together. The insertable storage mesh frame 3 facilitates quick and easy retrieval. Three sets of drive shafts 53 are arranged vertically and are connected to three sets of flipping discs 5. The drive shafts 53 (sealed at the connection between the drive shafts 53 and the yak jerky dryer 1 using gaskets or similar methods) are driven by the main and driven pulleys (coated with an anti-slip coating) of the first pulley assembly 55 and the second pulley assembly 56, and the belts, causing them to rotate synchronously. This rotates and flips the storage mesh frame 3 inside the yak jerky dryer 1, preventing the yak jerky from sticking to the mesh surface and making it difficult to peel off, thus ensuring the integrity of the yak jerky after low-temperature drying.

[0025] This utility model's low-temperature drying equipment for yak jerky processing effectively solves the problem in existing technologies where the heating wire is located at the bottom of the tray, resulting in the highest drying temperature at the bottom of the material. When stirring the material in the tray, this often leads to insufficient drying and multiple pieces of jerky sticking together. It facilitates real-time turning of the yak jerky during low-temperature drying, enhancing the uniformity of heating and drying, preventing the jerky from sticking to the mesh frame and becoming difficult to peel, ensuring the integrity of the yak jerky after low-temperature drying, and improving the production quality of the low-temperature drying equipment. This equipment is suitable for low-temperature drying of yak jerky.
