Abstract
Description
Technical Field
[0001] This utility model relates to the field of shrimp processing technology, and more specifically, to a low-temperature drying device for shrimp. Background Technology
[0002] Skewered shrimp typically refers to shrimp that are threaded onto skewers for use in various dishes, especially barbecue dishes. Before skewering, the shrimp need to be dried to remove surface moisture.
[0003] Currently, traditional shrimp drying typically uses hot air drying. While hot air drying can quickly remove surface moisture, the high temperature causes the proteins in the shrimp meat to denature and coagulate rapidly, and the muscle fibers to contract severely, quickly removing moisture. This results in dried shrimp that is hard, tough, and sometimes even rubbery, making it difficult to chew and virtually impossible to recreate the texture of fresh shrimp when eaten. Ordinary low-temperature drying or ambient-temperature drying equipment generally includes a conveyor belt and a fan positioned above it. Due to the lower temperature, the side of the shrimp that is attached to the conveyor belt does not dry easily, requiring the conveyor belt to be lengthened, extending the drying time, or the shrimp to be turned over, which makes the process cumbersome. Utility Model Content
[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a low-temperature drying device that can simultaneously transfer and air dry shrimp from both the top and bottom.
[0005] To solve the above problems, the present invention adopts the following technical solution.
[0006] A low-temperature drying device for shrimp, comprising: frame; A transmission mechanism is mounted on the frame; the transmission mechanism has a transmission belt for transporting shrimp, and the transmission belt has several through holes. A plurality of first fans are spaced apart on the frame along the conveyor belt's transport direction and located above the conveyor belt, with their airflow direction facing the conveyor belt; and Several second fans are spaced apart on the frame along the conveyor belt's transmission direction and located below the conveyor belt, with their airflow direction facing the conveyor belt.
[0007] Compared with the prior art, the present invention has at least the following beneficial effects: The first and second fans use ambient temperature air drying, which only removes moisture from the surface of the shrimp without cooking the shrimp meat, thus ensuring the fresh taste of the shrimp. By setting the first and second fans vertically, as well as the through holes on the conveyor belt, the upper and lower surfaces of the shrimp can be dried simultaneously, thereby shortening the drying process, avoiding the tedious process of turning the shrimp over, and ensuring the drying effect.
[0008] In some embodiments, the first fan and the second fan are arranged alternately, one above the other.
[0009] In some embodiments, the blowing directions of the first fan and the second fan are both inclined to the surface of the conveyor belt and are not arranged opposite each other.
[0010] In some embodiments, the transmission mechanism further includes: Two drive rollers, rotatably mounted at both ends on the frame, and horizontally spaced apart; and A drive unit is mounted on the frame and its output end is connected to one of the transmission rollers for driving the transmission roller to rotate. The conveyor belt is driven on two drive rollers, so that the conveyor belt has two layers, one above the other; the second fan is located between the two layers of the conveyor belt.
[0011] In some embodiments, the transmission mechanism further includes at least one limiting roller rotatably disposed at both ends on the frame and located below the two transmission rollers; the limiting roller is driven in conjunction with the transmission belt, thereby increasing the distance between the upper and lower layers of the transmission belt.
[0012] In some embodiments, the first fan is mounted on the frame via a support member.
[0013] In some embodiments, the frame has two spaced-apart mounting plates; the second fan is mounted on the side wall of the mounting plates via a connector. Attached Figure Description

[0016] 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.
[0017] refer to Figure 1-2 A low-temperature drying device for shrimp includes: a frame 1, a conveying mechanism 2, several first fans 3, and several second fans 4. The conveying mechanism 2 is mounted on the frame 1; the conveying mechanism 2 has a conveyor belt 21 for conveying shrimp, and the conveyor belt 21 has several through holes 211. The several first fans 3 are spaced apart on the frame 1 along the conveying direction of the conveyor belt 21, located above the conveyor belt 21, and blowing air towards the conveyor belt 21. The several second fans 4 are spaced apart on the frame 1 along the conveying direction of the conveyor belt 21, located below the conveyor belt 21, and blowing air towards the conveyor belt 21.
[0018] Understandably, the frame 1 is the supporting base component of the entire drying device, and can be, for example, a frame structure, a structure with two spaced-apart fixed plates 11, etc., but is not limited to these. The conveyor belt 21 can be a belt with through holes 211, or it can be a chain-type or mesh-type conveyor belt 21, etc., but is not limited to these. The first fan 3 and the second fan 4 are both components for blowing air onto the shrimp, and can be, for example, centrifugal fans, axial flow fans, etc., but are not limited to these.
[0019] With this setup, the first fan 3 and the second fan 4 use ambient temperature air drying, which only removes moisture from the surface of the shrimp without cooking the shrimp meat, thus ensuring the freshness of the shrimp. By positioning the first fan 3 and the second fan 4 vertically, and by using the through holes 211 on the conveyor belt 21, the upper and lower surfaces of the shrimp can be dried simultaneously. This shortens the drying process, avoids the tedious process of turning the shrimp over, and ensures the drying effect.
[0020] In some embodiments, the first fan 3 and the second fan 4 are arranged vertically alternately. This staggered arrangement means they are not positioned opposite each other; that is, the second fan 4 is positioned below the two adjacent first fans 3. In this way, the air blown by the first fans 3 and the second fans 4 will not blow against each other, thus preventing a reduction in airflow force.
[0021] In some embodiments, reference Figure 3 The air blowing direction of the first fan 3 and the second fan 4 is inclined to the surface of the conveyor belt 21 and is not set opposite to each other.
[0022] Understandably, "not relative setting" means that the airflow is not directed at each other. For example, if the first fan 3 blows air in a downward-left direction, the second fan 4 blows air in a upward-left direction. Similarly, if it blows air in a downward-right direction, it blows air in a corresponding upward-right direction.
[0023] This setup can mitigate the weakening effect of opposing wind forces to some extent.
[0024] In some embodiments, reference Figure 2 The transmission mechanism 2 further includes two drive rollers 22 and a drive unit 23. The two drive rollers 22 are rotatably mounted on the frame 1 at both ends and are horizontally spaced apart. The drive unit 23 is mounted on the frame 1 and its output end is connected to one of the drive rollers 22 to drive the drive roller 22 to rotate. The transmission belt 21 is driven onto the two drive rollers 22, so that the transmission belt 21 has two layers, one above the other. The second fan 4 is located between the two layers of the transmission belt 21.
[0025] Understandably, the transmission configuration between the drive roller 22 and the transmission belt 21 can be a gear and rack meshing transmission, or a tension friction engagement between the drive roller 22 and the transmission belt 21, etc., but is not limited to these. The drive unit 23 can be driven by a motor directly connected to the shaft end of the drive roller 22, or by a combination of a motor and a reducer, transmission gear set, etc., but is not limited to these.
[0026] With this configuration, the drive unit 23 drives the transmission roller 22 to rotate, which in turn drives the entire conveyor belt 21 for transmission. The second fan 4 is located between the upper and lower conveyor belts 21, so that the air blown by the second fan 4 can directly pass through one layer of conveyor belt 21 to dry the shrimp on the conveyor belt 21, reducing airflow loss.
[0027] In some embodiments, the transmission mechanism 2 further includes at least one limiting roller 24 rotatably disposed on the frame 1 at both ends and located below the two transmission rollers 22; the limiting roller 24 is driven to cooperate with the transmission belt 21, thereby increasing the distance between the upper and lower layers of the transmission belt 21.
[0028] Understandably, if only one limiting roller 24 is set, the entire conveyor belt 21 will be inverted triangular in shape. If two limiting rollers 24 are set, the conveyor belt 21 can be set into an inverted trapezoid or square shape, etc., but is not limited to these.
[0029] This setup can greatly increase the distance between the upper and lower conveyor belts 21, ensuring sufficient space to accommodate the installation of the second fan 4.
[0030] In some embodiments, the first fan 3 is mounted on the frame 1 via a support member 31. Here, the support member 31 is a component used to install and support the first fan 3, and may be, for example, a bridge frame structure, a bent arm structure, etc., but is not limited thereto. In this way, the first fan 3 can be stably fixed above the conveyor belt 21.
[0031] In some embodiments, the frame 1 has two spaced-apart fixing plates 11; the second fan 4 is mounted on the side wall of the fixing plate 11 via a connector. Here, the connector can be a plate or a rod, etc., and can be connected to one or both side walls of the fixing plate 11. This ensures stable mounting of the second fan 4.
[0032] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
