Description

Technical Field

[0001] This utility model relates to the technical field of bait production equipment, and in particular to a drying device for producing bait. Background Technology

[0002] Erkuai is a traditional rice-based food from Yunnan and Guizhou provinces in China, with Yunnan being the most famous for it. During the production of Erkuai, drying equipment is usually used to reduce its moisture content and extend its shelf life. By drying Erkuai, the core issue of regional delicacies reaching a wider market is solved, which is an important step in the industrialization of traditional food.

[0003] Drying equipment is usually either conveyor-type or box-type. Conveyor-type dryers mainly consist of a conveyor assembly and a drying assembly. After the produced bait blocks are placed above the inlet of the conveyor belt, the bait blocks enter the drying assembly below and are dried. The dried bait blocks are then output from the end of the conveyor belt.

[0004] When existing conveyor-type drying equipment is used to dry cylindrical bait blocks, there is a significant problem with uniformity. Specifically, as the hot airflow generated by the equipment blows towards and comes into contact with the cylindrical bait block, the airflow mainly diffuses outwards along the top surface of the bait block due to the obstruction at the top of the bait block. This flow pattern makes it difficult for most of the hot airflow to effectively contact and circulate around the lower half and near-bottom area of ​​the bait block, resulting in a significant reduction in the heat exchange efficiency of this local area and uneven heating of the material. Utility Model Content

[0005] The purpose of this invention is to solve the problem of uneven drying of columnar bait blocks in existing transmission and conveying type drying equipment, and to propose a drying equipment for producing bait blocks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A drying device for producing bait cakes includes a conveying assembly mounted on a frame. A drying hood is fixedly mounted on the frame, and an installation box is fixedly mounted on the drying hood. Inside the installation box, from top to bottom along its vertical direction, a drying component, a flow divider, a flow equalization plate, and a flow guide plate are fixedly mounted. A flow divider zone is formed between the flow divider and the installation box. When airflow passes through the flow divider zone, the airflow is divided by the flow divider. The flow equalization plate has equidistantly arranged tapered through holes, forming a pressurization zone between the flow divider and the flow equalization plate. When airflow passes through the flow equalization plate, the airflow is squeezed by the tapered through holes. An arc-shaped guide hood is fixedly mounted at the air outlet end of the installation box. A flow guide zone is formed between the flow guide plate and the guide hood. When airflow passes through the flow guide plate, part of the airflow is guided by the flow guide plate into the flow guide zone.

[0008] To ensure the normal operation of the drying equipment, preferably, the drying components include a filter plate, a fan, and a heating wire, which are installed sequentially from top to bottom in the mounting box. The air inlet of the fan faces the filter plate, and the air outlet of the fan faces the heating wire. When the fan is running, it draws airflow from outside the equipment into the mounting box and blows it onto the heating wire.

[0009] To prevent water droplets on the drying hood from affecting the drying of the bait, preferably, the drying hood is arc-shaped, and horizontal plates are symmetrically installed at the bottom of the drying hood. Each horizontal plate is equipped with a partition, and a drain groove is opened on the side of the partition away from the conveying component to drain the liquid on the drying hood.

[0010] To prevent the flowing liquid from contacting the bait, the cross-section of the spacer is further configured as a triangle, with the side of the spacer near the conveying assembly used to guide the hot airflow, and the other side used to intercept the liquid flowing down from the drying hood.

[0011] To reduce the influence of eddies, preferably, both ends of the flow divider are provided with prismatic protrusions, and the connection between the protrusions and the flow divider is rounded to guide the airflow smoothly through the flow divider area.

[0012] To prevent excessive gas in the pressurization zone, preferably, the ratio of the area of ​​the flow equalization plate to the total area of ​​the through holes is 2:1.5.

[0013] Compared with the prior art, this utility model provides a drying device for producing bait cakes, which has the following beneficial effects:

[0014] 1. The drying equipment for producing bait blocks uses a combination of a diversion grid, a flow equalization plate, and a flow guide plate. On the one hand, it makes the airflow more evenly blown onto the bait blocks. On the other hand, the flow guide plate, together with the guide hood, allows some airflow to blow onto the columnar bait blocks from the side, increasing the area that the hot air can cover on the bait blocks, thereby improving the drying effect and avoiding the problem that the lower half of the side of the columnar bait blocks will not be dried well due to the diversion of the gas after contact with the columnar bait blocks.

[0015] 2. The drying equipment for producing bait blocks uses a pressurization zone formed between the diversion grid and the flow equalization plate. This allows the hot airflow to be continuously pressurized by the subsequent airflow pressure and flow downwards towards the flow equalization plate. At the same time, when the hot airflow passes through the flow equalization plate, the gradually narrowing through holes further increase the flow velocity of the airflow, thereby improving the penetration effect of the hot airflow.

[0016] The parts not mentioned in this device are the same as or can be implemented using existing technology. This utility model uses a combination of a flow divider, a flow equalization plate and a flow guide plate to effectively improve the drying effect while avoiding the problem of airflow being diverted after contacting the surface of the bait block, resulting in poor drying effect in the lower half of the side of the columnar bait block.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0025] Example:

[0026] Reference Figures 1-5A drying device for producing bait cakes includes a conveying assembly 1 mounted on a frame. A drying hood 2 is fixedly mounted on the frame, and an installation box 3 is fixedly mounted on the drying hood 2. Inside the installation box 3, from top to bottom along its vertical direction, a drying component, a flow divider 4, a flow equalization plate 5, and a guide plate 6 are sequentially fixedly mounted. A flow divider zone is formed between the flow divider 4 and the installation box 3. Both ends of the flow divider 4 are provided with prismatic protrusions, and the connection between the protrusions and the flow divider 4 is rounded to guide the airflow smoothly through the flow divider zone and reduce the influence of eddies on the airflow. When the airflow passes through the flow divider zone, the airflow is divided by the flow divider 4, forming multiple smaller airflow streams, thereby increasing the stability of the airflow. The flow equalization plate 5 has equidistant rows of... The gradually narrowing through-holes of the cloth form a pressurization zone between the flow distribution grid plate 4 and the flow equalization plate 5. When the airflow passes through the flow equalization plate 5, the airflow is squeezed by the gradually narrowing through-holes, thereby accelerating the airflow through the gradually narrowing through-holes and improving the airflow penetration effect, thus improving the drying effect. An arc-shaped guide hood 31 is fixedly installed at the air outlet of the mounting box 3. A guide zone is formed between the guide plate 6 and the guide hood 31. When the airflow passes through the guide plate 6, part of the airflow is guided by the guide plate 6 to the guide zone. The airflow in the guide zone is affected by the guide hood 31, causing the airflow to be blown out along the tangential direction of the guide hood 31 and blown towards the lower half of the side of the columnar bait block, thereby improving the drying effect and avoiding the problem of uneven drying caused by poor drying effect in some areas.

[0027] Specifically, through the combined use of the diversion grid plate 4, the flow equalization plate 5, and the flow guide plate 6, the airflow is more evenly distributed to the bait block. On the other hand, the flow guide plate 6, in conjunction with the guide cover 31, allows some airflow to be blown from the side onto the columnar bait block, increasing the area that the hot air can cover, thereby improving the drying effect and avoiding the problem of poor drying effect on the lower half of the side of the columnar bait block due to the diversion of gas after contact with it. Through the pressurization zone formed between the diversion grid plate 4 and the flow equalization plate 5, the hot airflow is continuously subjected to the pressure of the subsequent airflow in the pressurization zone and is pressurized to flow downwards towards the flow equalization plate 5. At the same time, when the hot airflow passes through the flow equalization plate 5, the gradually narrowing through-hole further increases the flow velocity of the airflow, thereby improving the penetration effect of the hot airflow.

[0028] The drying components include a filter plate 7, a fan 8, and a heating wire 9, which are installed sequentially from top to bottom in the mounting box 3. The air inlet of the fan 8 faces the filter plate 7, and the air outlet of the fan 8 faces the heating wire 9. When the fan 8 is running, it draws the airflow from outside the equipment into the mounting box 3 and blows it toward the heating wire 9. By placing the heating wire 9 inside the mounting box 3, the distance between the heating wire 9 and the surface of the conveyor belt is reduced, thereby reducing the heat loss during the flow of hot air.

[0029] The drying hood 2 is designed to be arc-shaped, and horizontal plates are symmetrically installed at the bottom of the drying hood 2. Each horizontal plate is equipped with a partition strip 21. A drain trough 22 is opened on the side of the partition strip 21 away from the conveying component 1. The drain trough 22 is inclined and is used to drain the liquid on the drying hood 2. Some of the hot air blown towards the bait will rise to the surface. At this time, affected by the hot air blown out of the installation box 3, some hot air will remain in the drying hood 2 and undergo heat exchange to form water droplets that adhere to the drying hood 2. At this time, the water droplets are affected by the arc-shaped drying hood 2 and flow along the inner wall of the drying hood 2 to the horizontal plate, and then flow out through the drain trough 22. This effectively avoids the problem of condensed liquid dripping onto the bait, which would reduce the drying effect.

[0030] The cross-section of the partition 21 is set as a triangle. The side of the partition 21 near the conveying component 1 is used to guide the hot airflow, while the other side is used to intercept the liquid flowing down from the drying hood 2. The hot airflow flows into the drying hood 2 through the partition 21, and the water droplets that have completed heat exchange and condensation are affected by their own gravity and the curved drying hood 2, causing the water droplets to flow along the inner wall of the drying hood 2. At the same time, the partition 21 can prevent the water droplets from flowing to the vicinity of the conveyor belt, avoiding contact between the liquid and the bait, thereby affecting the drying effect.

[0031] The ratio of the area of ​​the flow equalization plate 5 to the total area of ​​the through holes is 2:1.5. On the one hand, it intercepts part of the hot airflow, causing the hot airflow to stay in the pressurization zone and pressurize the airflow. On the other hand, it compresses the airflow passing through the flow equalization plate 5, thereby increasing the speed of the airflow after passing through the flow equalization plate 5.

[0032] In this invention, the bait block is placed at the inlet end of the conveyor belt. When the conveyor belt in the conveyor assembly 1 is working, the bait block is moved into the drying hood 2. At this time, the fan 8 and the heating wire 9 are started. The fan 8 draws outside air into the installation box 3. Then the airflow completes heat exchange through the heating wire 9. After further heating, the airflow passes through the diversion grid plate 4, which divides the hot air into multiple streams and makes the airflow flow stably. Then the airflow enters the pressurization zone. After part of the airflow is blocked by the flow equalization plate 5, the airflow in the pressurization zone is compressed. The airflow through the flow equalization plate 5 is compressed by the gradually narrowing through holes. Combined with the airflow compression in the pressurization zone, the airflow speed through the flow equalization plate 5 is increased. Then the airflow is intercepted by the guide plate 6, which diverts the airflow again. Part of the airflow enters the guide zone and flows along the guide hood 31. The sprayed gas contacts the side of the bait block, while another part of the airflow blows directly downward and contacts the top of the bait block, thereby realizing the contact area between the hot air and the bait block, improving the drying effect, and avoiding the problem of poor drying effect in the lower half of the side of the columnar bait block.

[0033] When some of the hot air rises, it enters the space between the drying hood 2 and the mounting box 3. When the hot air comes into contact with the drying hood 2, a heat exchange reaction occurs and it condenses into water droplets. The liquid is affected by the arc-shaped drying hood 2 and its own gravity, causing the water droplets to flow onto the horizontal plate and be discharged through the drain trough 22. This effectively avoids the liquid from coming into contact with the bait blocks, thus preventing the drying effect from being reduced.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
