Dryer for processing selenium-enriched chicken feed Technical Field
[0001] This utility model relates to the field of feed processing equipment technology, and in particular to a dryer for processing selenium-enriched chicken feed. Background Technology
[0002] In the selenium-enriched chicken feed production industry, the drying process plays a crucial role in product quality. Traditional drying equipment mostly uses stirring to dry the feed.
[0003] In traditional drying equipment, the constant friction and collision between feed particles and the mixing components during the mixing process can easily damage the physical structure of the feed, such as causing it to crumble or break. This not only affects the appearance of the feed but may also destroy its nutrients, reducing its quality. Furthermore, mixing-type drying makes it difficult to ensure even heat transfer to every single grain, often resulting in some parts of the feed being over-dried and losing nutrients, while other parts are under-dried, affecting product consistency and overall quality. Summary of the Invention

[0005] A dryer for processing selenium-enriched chicken feed includes a drying drum, a feeding assembly, a drying assembly, and a controller. The feeding assembly is located at the top of the drying drum to guide the material into the interior of the drying drum. The drying assembly includes multiple drying units arranged axially toward the drying drum. Each drying unit includes two sets of air outlet pipes installed facing each other inside the drying drum, and a hot air blower connected to the air outlet pipes. The controller is used to control the wind speed of the hot air blower.
[0006] As an improvement to the above technical solution: the drying components are provided in three groups, which are arranged sequentially in the upper, middle and lower parts of the drying cylinder. When drying materials, the controller controls the air speed of the hot air blowers located in the upper, middle and lower parts of the drying cylinder to increase sequentially.

[0008] As an improvement to the above technical solution: the inner wall of the drying cylinder and below the main air outlet is connected to an inclined downward guide plate.
[0009] As an improvement to the above technical solution, it also includes an external frame, on which both the drying cylinder and the hot air blower are mounted.
[0010] As an improvement to the above technical solution: the feeding assembly includes a storage box installed on the top of the outer frame, the bottom of the storage box is connected to a discharge hopper, the bottom of the discharge hopper has a discharge port, and the discharge port extends to the top of the inside of the drying cylinder.
[0011] As an improvement to the above technical solution: the bottom surface of the discharge port is in contact with a material distribution plate, and an electric telescopic rod is installed on the side of the discharge port. The output rod of the electric telescopic rod is connected to the material distribution plate, and the electric telescopic rod is used to drive the material distribution plate to block, not block, or partially block the discharge port.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0020] Example
[0021] Referring to Figures 1-3, the dryer for processing selenium-enriched chicken feed provided by this utility model includes a drying cylinder 2, a feeding assembly, a drying assembly, and a controller. The feeding assembly is located at the top of the drying cylinder 2 and is responsible for conveying the selenium-enriched chicken feed to be dried into the drying cylinder 2. The drying assembly is distributed along the axial direction of the drying cylinder 2 and consists of multiple drying units. Each drying unit includes two sets of air outlet pipes 31 installed opposite to each other inside the drying cylinder 2 and a hot air blower 3 connected to them. The controller is used to precisely control the air speed of the hot air blower 3 to meet different drying requirements.
[0022] The drying assembly consists of three sets, installed at the top, middle, and bottom of the drying drum 2, respectively. During actual drying operations, the controller will control the airflow speed of the hot air blowers 3 located at the top, middle, and bottom of the drying drum 2 to increase sequentially according to a preset program. This gradient airflow design fully considers the weight differences of the feed pellets. Lighter feed pellets can be suspended in the air under the action of lower airflow speed at the top, achieving efficient drying; medium-weight feed pellets float and dry under slightly higher airflow speed in the middle; and heavier feed pellets rely on higher airflow speed at the bottom to complete the drying process, thereby significantly improving drying efficiency and quality.
[0023] The air outlet duct 31 is located at the inner end of the drying cylinder 2 and is connected to the arc-shaped main air outlet duct 32. Several branch air outlet ducts 33 are evenly distributed inside the main air outlet duct 32. The arc-shaped main air outlet duct 32 allows hot air to be more evenly distributed into the drying cylinder 2. Combined with multiple branch air outlet ducts 33, it effectively expands the contact area between hot air and feed, ensuring the uniformity of the drying process and further improving the drying effect.
[0024] An inclined guide plate 4 is connected to the inner wall of the drying drum 2, below the main air outlet duct 32. After drying is completed, the hot air fan 3 is turned off, and the dried feed slides smoothly down the guide plate 4 under gravity into the receiving box 7 below. Meanwhile, to ensure the stability and reliability of the equipment, an external frame 1 is installed, and the drying drum 2 and hot air fan 3 are both securely mounted on the external frame 1. The external frame 1 not only provides solid support for each component but also enhances the overall stability of the equipment and reduces vibration and noise during operation.
[0025] The feeding assembly mainly consists of a storage bin 5 installed on the top of the outer frame 1 and a discharge hopper 6 connected to its bottom. The discharge port 60 at the bottom of the discharge hopper 6 extends to the top of the inside of the drying cylinder 2, ensuring that the feed can fall directly into the drying cylinder 2, thus achieving efficient feeding.
[0026] The bottom surface of the discharge port 60 is in close contact with the distribution plate. An electric telescopic rod 8 is installed on the side of the discharge port 60, and its output rod is connected to the distribution plate. By controlling the extension and retraction of the electric telescopic rod 8, the position of the distribution plate can be flexibly adjusted to achieve complete sealing, partial opening or complete opening of the discharge port 60, thereby precisely controlling the flow rate of feed in the storage box 5 into the drying cylinder 2 to meet different production process requirements.
[0027] A receiving box 7 is installed at the bottom of the drying drum 2 to collect the feed that slides down through the guide plate 4 after drying. The design of the receiving box 7 realizes the integrated operation of drying and collection, simplifies the production process, and improves production efficiency.
[0028] When drying feed, connect the power supply to the equipment, start the controller, and initialize the equipment. Based on the characteristics of the selenium-enriched chicken feed to be dried, such as particle size and moisture content, set the airflow parameters of the hot air blower 3 on the controller. Pour the feed to be dried into the storage bin 5.
[0029] The electric telescopic rod 8 is activated by the controller to adjust the position of the feed distribution plate, allowing the feed in the storage bin 5 to enter the top of the drying cylinder 2 from the discharge port 60 at an appropriate flow rate. For example, for feed with high moisture content and large particle size, the opening degree of the feed distribution plate can be appropriately increased to improve the feeding speed; for feed with low moisture content and small particle size, the opening degree of the feed distribution plate can be decreased to control the feeding speed.
[0030] When the hot air blower 3 is turned on, the hot air generated by the hot air blower 3 enters the drying cylinder 2 through the air outlet duct 31, the main air outlet duct 32, and the branch air outlet duct 33. At this time, feed particles of different weights are suspended and dried under the action of corresponding air speeds. That is, the lighter feed particles will float in the air under the action of the upward airflow generated by the opposing air speeds of the two sets of air outlet ducts 31 at the top. The hot air comes into full contact with these suspended feed particles, and the moisture in the feed is removed through heat transfer, achieving effective drying.
[0031] Medium-weight feed pellets will fall a certain distance under the influence of gravity. At this point, the hotter air with a higher wind speed discharged from the two sets of central air outlets 32 will counteract the weight and float the pellets in the air, thus drying them. Similarly, heavier feed pellets, after passing through the top and middle airflow areas, will eventually float up under the influence of the hotter air with the highest wind speed discharged from the two sets of bottom air outlets 32, completing the drying process.
[0032] During the drying process, hot air is evenly distributed within the drying drum 2 by the arc-shaped main exhaust pipe 32 and multiple branch exhaust pipes 33, ensuring uniform heating of all parts of the feed. After a period of drying, once the moisture content of the feed reaches the expected standard, the hot air blower 3 is turned off. At this point, the dried feed slides down the inclined guide plate 4 along the inner wall of the drying drum 2 under gravity, finally falling into the receiving box 7 at the bottom of the drying drum 2, completing the entire drying process.
[0033] During the drying process, the extension and retraction of the electric telescopic rod 8 can be adjusted in real time via the controller according to the actual situation to precisely control the feed flow rate and ensure the stability and continuity of the drying process. Simultaneously, the drying status can be observed, and the air speed of the hot air blower 3 can be adjusted if necessary.
[0034] After the preset drying time, the hot air blower 3 is turned off. At this time, the dried feed slides down the guide plate 4 into the receiving box 7 under the action of gravity. After the receiving box 7 has collected a certain amount of feed, it can be centrally processed, such as packaged or stored. After one batch of feed has been dried, the next batch can be dried as needed.
[0035] In some optional embodiments of this application, temperature or humidity sensors connected to a controller are installed in the upper, middle, and lower layers inside the drying drum 2 to monitor the temperature inside the drying drum 2 in real time. The temperature of the hot air blown out by the hot air blower 3 can be precisely adjusted according to the type and humidity of the feed to avoid damaging the nutritional components of the feed due to excessively high temperatures or resulting in low drying efficiency due to excessively low temperatures. For example, for heat-sensitive selenium-enriched chicken feed, the temperature can be controlled within a suitable range.
[0036] A humidity sensor installed inside the drying drum 2 provides real-time feedback on the feed's moisture level. Based on this humidity data, parameters such as the feeding speed, hot air fan 3's speed, and temperature are automatically adjusted to achieve more precise drying control. When low feed moisture is detected, the hot air fan 3's speed and temperature can be appropriately reduced, and the feed rate decreased to prevent over-drying.
[0037] Furthermore, the existing discharge hopper 6 only controls the feed flow rate through the distribution plate. This application can add a stirring or dispersing device inside the discharge hopper 6. This prevents the feed from clumping or clogging at the outlet of the storage bin 5, ensuring that the feed enters the drying cylinder 2 evenly and smoothly, and improving the consistency of drying.
[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
