Description

Technical Field

[0001] The present invention relates to the technical field of tsaoko drying, and in particular to drying equipment and a drying method for tsaoko. Background Art

[0002] The dried, mature fruit of the tsaoko tree can be used as a traditional Chinese medicine and a culinary condiment, adding flavor and removing fishy smells. It is widely used as a seasoning in food processing. However, if the tsaoko tree is not dried promptly after harvest, it can easily become moldy and spoil. Natural drying takes a long time and is labor-intensive, and inclement weather can also cause mold and spoilage.

[0003] Drying is a common industrial drying method that uses high temperatures to evaporate water from the tsaoko. During the drying process, the volatile components of the tsaoko are also affected. The tsaoko on the sieve rack close to the heat source is heated quickly and at a high temperature, which accelerates the evaporation of volatile components in the tsaoko near the heat source. This allows the drying process to be completed in a shorter time, but this can result in uneven heating of multiple layers of tsaoko. This can cause the tsaoko near the heat source to dry, but the tsaoko far from the heat source to not be completely dry. The tsaoko near the heat source is heated for a long time, which can lead to the decomposition and loss of some volatile components after drying, and can also easily reduce its flavor and quality. This can cause the tsaoko in different layers to have different qualities after drying, affecting its quality. Summary of the Invention

[0004] The object of the present invention is to provide a drying device and a drying method for tsaoko, which have the advantages of making the tsaoko on each mesh plate evenly contact the heat source, improving the drying uniformity, avoiding the uneven drying quality of the tsaoko due to temperature difference, improving the quality of the tsaoko after drying, and avoiding the volatile components of the tsaoko being affected, thereby reducing its flavor and quality.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] In order to better understand the drying equipment and drying method of the tsaoko provided in this embodiment, the following first briefly introduces the existing drying equipment of the tsaoko. In order to solve the problem of uneven heating of the tsaoko during the drying process in the prior art, most of the prior art heats the tsaoko in the drying box on four or six sides by adding air vents. Although the tsaoko on the outer edges can be heated evenly, the tsaoko in the middle cannot be heated in time, and the tsaoko cannot be turned over, resulting in the tsaoko being in a static state all the time, and one side cannot be heated well, resulting in slow drying efficiency. The specification aims to solve the above technical problems. The embodiment of the present application provides a drying equipment and drying method for the tsaoko.

[0036] Example 1: Reference Figure 1 - Figure 8 , which is a first embodiment of the present invention, provides a drying device for tsaoko, comprising a drying box 1 and a drying system 11 with an air outlet arranged above the drying box 1, wherein a rotary circulation driving member 2 is arranged inside the drying box 1, and a plurality of storage brackets 3 are equidistantly installed on the rotary circulation driving member 2, and a mesh disk 31 for placing tsaoko is arranged on the storage bracket 3, and the plurality of storage brackets 3 move together with the rotary circulation driving member 2 and pass under the air outlet in sequence, so that the tsaoko on each mesh disk 31 is evenly exposed to the heat source, thereby improving the uniformity of drying, avoiding that the tsaoko close to the air outlet is always heated, and avoiding that the drying quality of tsaoko is uneven due to temperature difference, and improving the quality of tsaoko after drying by turning the tsaoko over during drying, and avoiding that the volatile components of tsaoko are affected and thus reducing its flavor and quality;

[0037] A flipping part 4 is provided in the drying box 1. When each of the storage brackets 3 moves to the bottom of the air outlet, the flipping part 4 flips the cardamom placed on the mesh disk 31. It should be noted that since the cardamom needs to be cleaned before drying, when the cleaned cardamom is placed on the mesh disk 31, some water will be wrapped on the surface. During the drying and static process, the water on the surface of the cardamom will gather at the place where the cardamom contacts the mesh disk 31 below the cardamom, resulting in water accumulation under the cardamom, and when the cardamom moves to the place closest to the air outlet, the cardamom is turned over by the flipping part 4, and the hot air from the air outlet can quickly evaporate the water accumulated on the turned cardamom, avoiding the water accumulation time for too long, resulting in different drying speeds on the two sides, so that the outer surface of each cardamom can be evenly heated, accelerating the drying speed and improving the drying efficiency.

[0038] The rotating circulation drive member 2 includes a walking track 21, a moving chain belt 22 and a driver 23. The walking track 21 is symmetrically opened on the inner walls of both sides of the drying box 1. A circulating rotating moving chain belt 22 is arranged in the walking track 21. The drying box 1 is provided with a driver 23 that drives the moving chain belt 22 to rotate. The driver 23 drives the moving chain belt 22 to rotate, and the moving chain belt 22 drives several storage racks 3 to rotate accordingly.

[0039] The storage bracket 3 is ring-shaped, and the outer wall of the storage bracket 3 is sleeved with an outer bearing 32. The arrangement of the outer bearing 32 does not affect the rotation of the storage bracket 3. Connecting rods 33 are symmetrically arranged on the outer walls on both sides of the outer bearing 32. One end of the two connecting rods 33 is connected to a limit plate 34. The limit plate 34 is connected to the movable chain belt 22 through an axle rod. A limit block 341 is provided at two corners on one side of the limit plate 34. A limit groove 12 matching the limit block 341 is provided on the inner wall of the drying box 1. When the storage bracket 3 moves with the movable chain belt 22, the limit plate 34 moves together. When the limit plate 34 moves, the limit blocks 341 at both ends of one side are limited and moved in the limit groove 12. The limit groove 12 and the limit block 341 slide in cooperation, thereby increasing the stability of the storage bracket 3 during the overall movement, reducing the pressure at the connection between the limit plate 34 and the movable chain belt 22, and improving the smoothness of movement.

[0040] The outer ring of the mesh disk 31 is provided with a circle of clamping ring 311, and the mesh disk 31 is clamped on the top of the storage bracket 3 through the clamping ring 311. There are several clamping columns in a circular array below the clamping ring 311. The upper end surface of the mesh disk 31 is provided with holes and grooves corresponding to the clamping columns. The mesh disk 31 is placed on the storage bracket 3 by being placed up and down. The entire mesh disk 31 can be removed, which is convenient for placing and taking materials. When placed, the clamping columns are inserted into the holes and grooves, so that the storage bracket 3 can rotate while driving the mesh disk 31 to rotate.

[0041] The flipping member 4 includes a flipping plate 41, a connecting seat 42, a mounting bracket 43 and a driving assembly 44. The flipping plate 41 is connected to the connecting seat 42 through a rod body. A driving shaft 421 is provided at both ends of the connecting seat 42. The driving shaft 421 is connected to the mounting bracket 43. A driving assembly 44 is installed on the side end of the mounting bracket 43. The driving assembly 44 is used to drive the storage bracket 3 to rotate. The driving assembly 44 includes a rotating rod 441, a driving gear 442 and an output shaft 443. The output shaft 443 is connected to one end of the rotating rod 441 by a universal joint. The other end of the rotating rod 441 is sleeved with a driving gear 442. It is sleeved with a linkage gear ring, which is movably engaged with the driving gear 442. When the storage bracket 3 moves to the bottom of the air outlet, the linkage gear ring on its surface abuts against the driving gear 442, and the linkage gear ring engages with the driving gear 442. The output shaft 443 rotates, driving the storage bracket 3 to rotate, and then driving the net disk 31 to rotate. The flipping plate 41 contacts the grass fruit on the net disk 31. During the rotation of the net disk 31, the flipping plate 41 relies on friction to turn the grass fruit on the net disk 31 separately, so that multiple sides of the grass fruit can be evenly heated, accelerating the drying speed, preventing moisture from remaining on the bottom side, and ensuring the quality of the dried licorice.

[0042] The rotating rod 441 is inserted into the limit seat 444, and a limit bracket 445 is provided on the outside of the limit seat 444 for limiting the sliding of the limit seat 444. The limit seat 444 and the limit bracket 445 are connected by a spring. One end of the drive shaft 421 is extended and connected to a vertical rod. One end of the vertical rod is connected to the mounting bracket 43 through a spring. The storage bracket 3 is movably connected to the extension rod of the connecting seat 42 through a linkage 5. When the storage bracket 3 is moved away from under the air outlet, the storage bracket 3 squeezes the driving gear 442 to rotate the rod 441 and the limiting seat 444 move upward along the limiting bracket 445 to prevent the driving gear 442 from blocking the movement of the storage bracket 3. During the movement of the storage bracket 3, the connecting rod 33 abuts against one end of the linkage member 5, squeezing one end of the linkage member 5 to tilt the linkage member 5, and the other end of the linkage member 5 squeezes the extension rod of the connecting seat 42 to make the flipping plate 41 tilt up without affecting the movement of the storage bracket 3. When the previous storage bracket 3 moves away, the flipping plate 41 and the driving gear 442 are reset under the action of the spring and are aligned with the next storage bracket 3 again.

[0043] The linkage part 5 is a combination of a bent plate 51 and a rotating shaft rod 52. The bent plate 51 can rotate around the rotating shaft rod 52, and one bent end of the bent plate 51 rests on the top of the extension rod of the connecting seat 42. When the storage bracket 3 moves to the bottom of the air outlet, the other end of the bent plate 51 is aligned with one side of the connecting rod 33.

[0044] The present invention provides a method for drying tsaoko, comprising the following steps:

[0045] S1: Place the tsaoko to be dried flat on the net plate 31, and then place the net plate 31 with the tsaoko in the storage rack 3 in sequence;

[0046] S2: After the tsaoko is placed, the drying box 1 is closed and the drying system 11 is started to dry the tsaoko;

[0047] S3: During the drying process, the driver 23 drives the movable chain belt 22 to rotate, and the movable chain belt 22 moves together, so that the plurality of storage racks 3 are sequentially close to the air outlet and pass under the air outlet;

[0048] S4: When the storage bracket 3 moves to below the air outlet, the linkage gear ring on the storage bracket 3 is aligned with the driving gear 442, and the output shaft 443 drives the rotating rod 441 to rotate through the universal joint, thereby driving the storage bracket 3 and the network disk 31 to rotate together;

[0049] S5: When the storage bracket 3 moves to the bottom of the air outlet, the turning surface of the turning plate 41 contacts the tsaoko on the mesh disk 31 . When the mesh disk 31 rotates, the turning plate 41 turns over the tsaoko on the mesh disk 31 .

[0050] S6: When the storage bracket 3 moves away from under the air outlet, the storage bracket 3 squeezes the driving gear 442, causing the rotating rod 441 and the limiting seat 444 to move upward along the limiting bracket 445, preventing the driving gear 442 from blocking the movement of the storage bracket 3. In addition, during the movement of the storage bracket 3, the connecting rod 33 abuts against one end of the linkage member 5, squeezing the one end of the linkage member 5 to tilt the linkage member 5, and the other end of the linkage member 5 squeezes the extension rod of the connecting seat 42, causing the flip plate 41 to tilt, without affecting the movement of the storage bracket 3.

[0051] S7: When the previous storage bracket 3 is removed, the turning plate 41 and the driving gear 442 are reset under the action of the spring and aligned with the next storage bracket 3 again to form a cyclic drying.

[0052] Embodiment 2:

[0053] The second embodiment is different from the first embodiment in that the driver 23 is a combination of a motor and a ratchet assembly. The motor output shaft is connected to the movable chain belt 22 through the ratchet assembly. The output end of the motor output shaft is connected to the output shaft 443 by a belt. When the motor rotates counterclockwise, it can drive the movable chain belt 22 to rotate, driving the storage bracket 3 to move in a circle. When the storage bracket 3 moves to the bottom of the air outlet, the motor rotates clockwise, and then drives the output shaft 443 to rotate, driving the storage bracket 3 to rotate on its own to turn the grass fruit over, thereby achieving drive continuity and saving the company's drive costs through a set of drives.

[0054] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
