Description

Technical Field

[0001] This utility model relates to the field of feed drying, and in particular to a Dongfeng snail feed dryer. Background Technology

[0002] The feed for *Bambusa multiplex* is mostly high in protein and nutrients. These materials are highly susceptible to the growth of mold, bacteria, and parasite eggs in humid environments. Undried feed typically has a moisture content exceeding 15%, creating ideal conditions for rapid microbial growth, leading to mold, spoilage, and the production of toxins such as aflatoxin. After ingesting this feed, *Bambusa multiplex* will experience a decrease in feed intake and stunted growth, and in severe cases, poisoning and death. Juvenile snails, in particular, are at higher risk due to their weaker immune systems.

[0003] Although current small and medium-sized drying equipment is all chamber-type structure, such as the existing technology CN218545090U equipment, it is usually an integrated equipment. It can only dry a single batch in the same chamber, and cannot form an assembly line operation, especially not a staged drying operation. The moisture extraction rate inside the feed is low, while the surface is too dry, thus affecting the drying quality of the feed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a Dongfeng snail feed dryer, which mainly solves the problem that the existing small and medium-sized drying equipment cannot form a staged drying operation and a production line operation for feed drying.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model relates to a Dongfeng snail feed dryer, comprising a chamber with a hollow interior. An open conveying mechanism is located on the bottom side of the chamber. A feed inlet is located at one end of the chamber, with its bottom positioned at one end of the conveying mechanism. The conveying mechanism moves from the feed inlet towards the other end. A primary heating chamber, a cooling chamber, and a heating chamber are sequentially arranged on the upper part of the conveying mechanism from the feed inlet to the other end. The bottom spaces of the primary heating chamber, cooling chamber, and heating chamber are interconnected. A fan and heating pipes are located on the top of the chamber. Both the primary heating chamber and the heating chamber are heated by the fan through the heating pipes. An exhaust vent is located on one side of the fan.

[0006] Preferably, the conveying mechanism includes: a conveying trough, which is located inside the bottom side of the compartment and extends through it from front to back; a through trough, which is located below the conveying trough and is separated from the conveying trough by a partition plate; a conveyor belt, which surrounds the conveying trough and the through trough and is located at the bottom of the compartment; and a drive motor, which drives the conveyor belt.

[0007] Preferably, the upper side of the interior of the compartment is provided with a perforated plate, a first partition is provided on one side of the middle of the perforated plate, a second partition is provided on the other side of the middle of the perforated plate, a preheating chamber is provided on the left side of the first partition, a heating chamber is provided on the right side of the second partition, and a cooling chamber is provided between the first partition and the second partition.

[0008] Preferably, the upper part of the perforated plate is provided with a heating pipe, the top of which is located in the middle of the top of the compartment. The heating pipe includes: a left pipe extending into the initial heating chamber, with a first heating module in the middle of the left pipe; and a right pipe extending into the heating chamber, with a second heating module in the middle of the right pipe.

[0013] Preferably, the bottom of the second partition is equipped with vertically extending grid bars, and the distance between the bottom of the grid bars and the conveyor belt does not exceed 2-4 cm.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features different chambers designed to work with the conveyor belt, allowing the fan to output power at a fixed rate within each chamber.

[0016] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0017] In the attached diagram, all identical reference numerals refer to the same components.

[0018] In the first embodiment, as Figure 1-3 As shown, this utility model provides a Dongfeng snail feed dryer, including a chamber 1. The interior of the chamber 1 has a hollow structure. An open conveying mechanism 2 is provided on the bottom side of the interior of the chamber 1. A feed inlet 3 is provided at one end of the chamber 1. The bottom of the feed inlet 3 is located at one end of the conveying mechanism 2, and the movement direction of the conveying mechanism 2 is from the feed inlet 3 to the other end. A primary heating chamber 4, a cooling chamber 5, and a heating chamber 6 are sequentially provided on the upper part of the conveying mechanism 2 from one end of the feed inlet 3 to the other end. A fan 7 and a heating pipe 8 are provided on the top of the chamber 1. The primary heating chamber 4 and the heating chamber 6 are heated by the fan 7 through the heating pipe 8. An exhaust port 9 is provided on one side of the fan 7. Its structure is shown in the reference. Figure 1-2 Because the feed for whelks is generally high in protein, it is extremely prone to bacterial growth in humid environments. However, current small and medium-sized drying equipment usually adjusts the drying degree according to the power, and the same equipment can only dry the same batch of feed. Therefore, this invention designs a chamber structure 1 that can form a stepped temperature-controlled chamber, so that the feed poured into the inlet 3 directly enters the conveying mechanism 2. Through the conveying mechanism 2, the feed passes through the primary heating chamber 4, the cooling chamber 5 and the heating chamber 6 respectively. The feed is dried and heated on the surface in the primary heating chamber 4, and then the cooling chamber 5 balances the internal moisture of the feed with the surface to prevent the surface of the pellets from forming a crust. Finally, the heating chamber 6 heats and dries the feed a second time, so that the hardness of the pellets meets the standard while minimizing the internal moisture.

[0019] Furthermore, please refer to the description of the conveying mechanism 2. Figure 1-3The conveyor belt 24 mainly surrounds the conveying trough 21 and the through trough 22. The drive shafts at both ends of the conveyor belt 24 are located at the front and rear ends of the box body 1 and are installed on the support 11 through the external two-sided fixed brackets, so that the drive motor can continuously drive the conveyor belt 24 to rotate inside the conveying trough 21 through the drive shaft. After the feed enters through the feed inlet 3, it will fall onto the conveyor belt 24, and the conveyor belt 24 will drive the feed to move at the bottom of different chambers.

[0020] Furthermore, to ensure that the internal temperatures of the initial heating chamber 4, cooling chamber 5, and heating chamber 6 are different, the different chambers are separated by a perforated plate 10 and a first partition 101 and a second partition 102 at the bottom. Both the first partition 101 and the second partition 102 are made of heat-insulating material. The bottom spaces are interconnected and heated by a motor and heating pipes 8. The heated and evaporated water will evaporate upwards from the vertical perforations on the surface of the perforated plate 10 to the upper part of the perforated plate 10 and be discharged from the exhaust port 9. If necessary, the exhaust port 9 can be extended upwards by a certain distance to avoid affecting the air intake space of the fan 7.

[0021] Furthermore, the blower 7 mainly transmits external airflow to the heating pipe 8. The heating pipe 8 is equipped with a first heating module 82 and a second heating module 84 on both the left and right sides. Controlled by the PLC controller, the heating temperature of the resistance temperature detector is sensed by the RTD module, so that the first heating module 82 and the second heating module 84 are respectively in the range of 50-60 degrees Celsius and 60-70 degrees Celsius. The air blown in by the blower 7 will be heated by the first heating module 82 and the second heating module 84 respectively, and output to the internal primary heating chamber 4 and heating chamber 6, so as to achieve the effect of different temperatures in the internal chambers. Although there is no airflow output from the pipe in the middle cooling chamber 5, the primary heating chamber 4 and the heating chamber 6 on both sides have a high temperature. As the heat source at both ends, the temperature in the middle will be kept below 40-50 degrees Celsius, so that the feed can be appropriately cooled in the middle without condensation due to excessive temperature difference.

[0022] Working principle: The operator mainly adjusts the first heating module 82 and the second heating module 84 through the PLC controller of the system host, and starts the fan 7 and drive motor. The system host includes an MCU control chip, which is connected to the above-mentioned electrical equipment to realize the control circuit system. Feed can then be poured into the feed inlet 3 and slowly conveyed by the conveyor belt 24. The system operates according to the control scheme inside the host computer. For example, the feed poured into the conveyor belt 24 first enters the heating chamber 6. The high temperature inside the heating chamber 6 causes the surface moisture of the feed to evaporate continuously. After 10 minutes, the feed on the conveyor belt 24 arrives at the cooling chamber 5. After 10 minutes, the feed is cooled in the cooling chamber 5 and then moves to the heating chamber 6. After 10 minutes, the feed is heated and then conveyed directly from the tail conveyor trough 21 to the outside storage by the conveyor belt 24, thus achieving a production line drying effect. When different time segments need to be adjusted, the dwell time can be changed according to the different lengths of the internal initial heating chamber 4, cooling chamber 5, and heating chamber 6. This is achieved by adjusting the installation positions of the first partition 101 and the second partition 102 on the perforated plate 10, which can be done by setting different timing sequences at both ends of the chamber. Figure 2 As shown: After the feed is poured into the right side of the initial heating chamber 4 for 5 minutes, it is poured into the left side of the initial heating chamber 4 again, forming two different piles of feed. This continues until the feed on the right side meets the 10-minute requirement, at which point it is moved to the cooling chamber 5 and cooled for 5 minutes. At this time, the feed on the left side of the initial heating chamber 4 will move to the right side, and then feed can be poured in again, and this cycle is repeated. The feed that has been cooled in the cooling chamber 5 can then enter the heating chamber 6 again for a secondary drying operation, which can also form the same pattern as the initial heating chamber 4 to dry the two piles of feed simultaneously.

[0023] In another embodiment, such as Figure 2 and 4 As shown, when the feed pile inside the initial heating chamber 4 moves into the cooling chamber 5, the higher feed pile will be blocked by the first partition 101, so that the piled feed is spread flat on the conveyor belt 24. Due to the temperature difference between the cooling chamber 5 and the initial heating chamber 4, i.e., the principle of hot air rising in the initial heating chamber 4 and the heating chamber 6, the internal temperature of the cooling chamber 5 remains within a certain range and does not change. Once the internal moisture of the feed in the cooling chamber 5 slowly migrates to the surface, it is easy for them to stick together. Therefore, a grid 1021 is provided at the bottom of the second partition 102, so that the grid 1021 can move into the heating chamber 6 in a flat and separated manner when the feed passes through, thereby increasing the drying efficiency inside the heating chamber 6 and reducing the time required for the conveyor belt 24 to stop.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
