Description

Technical Field

[0001] This utility model relates to the technical field of forage pellet processing equipment, specifically to a drying device for forage pellet production. Background Technology

[0002] With the continuous development of animal husbandry, forage pellets have been widely used as a high-quality form of feed. Forage pellets have advantages such as small size, high density, and ease of storage and transportation, effectively reducing nutrient loss during storage and improving forage utilization. Drying is a crucial step in the production of forage pellets, directly affecting their quality and shelf life.

[0003] Traditional forage pellet drying equipment mainly includes ovens and tunnel dryers. Oven drying involves placing forage pellets in a sealed chamber and evaporating moisture from the pellets by heating air. However, because the forage pellets are stationary during the drying process, the hot air cannot evenly reach each pellet, resulting in uneven drying. Some pellets may be over-dried, leading to significant nutrient loss, while others may be under-dried and prone to mold and spoilage. Furthermore, ovens have limited space, allowing for small batches and low drying efficiency, making them unsuitable for large-scale production.

[0004] Tunnel dryers, on the other hand, allow forage pellets to move slowly on a conveyor belt and be dried by hot air inside a tunnel. While this method addresses the issue of small drying capacity in ovens to some extent, the accumulation of forage pellets on the conveyor belt leads to uneven heat distribution as the hot air penetrates the pellet layer. Pellets near the hot air inlet dry quickly, while those at the interior and bottom dry slowly, resulting in uneven drying.

[0005] In summary, traditional forage pellet drying equipment has significant shortcomings in terms of drying uniformity and efficiency, making it difficult to meet the requirements of modern animal husbandry for efficient and high-quality forage pellet production. Therefore, it is necessary to develop a new type of drying device for forage pellet production to overcome the deficiencies of existing technologies. Utility Model Content

[0009] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a drying device for the production of grass pellets, including a shell with an open top, an arc-shaped groove inside the shell, a roller rotating inside the arc-shaped groove, a plurality of evenly distributed air holes on the side of the roller, a drive mechanism for driving the roller to rotate fixedly on the outside of the shell, a plurality of lifting plates fixedly on the inner wall of the roller, a hot air fan fixedly on the side of the shell, a first hot air outlet fixedly on the inner wall of the arc-shaped groove, the hot air fan being connected to the first hot air outlet, and a pipe being connected to the outlet of the hot air fan, the other end of the pipe extending into the inside of the roller and fixedly connected to a second hot air outlet.

[0010] Furthermore, the roller has a feed inlet on its side and a discharge outlet on its arc surface, with a sealing door on the discharge outlet.

[0011] Furthermore, the second hot air outlet faces downwards and its upper surface is arc-shaped.

[0012] Furthermore, the drive mechanism includes a motor fixedly mounted on the side of the housing, a drive wheel fixedly mounted on the drive shaft of the motor, and a driven wheel fixedly mounted on the end of the roller shaft. A belt connects the drive wheel and the driven wheel.

[0013] Furthermore, a discharge channel is provided between the side of the housing and the bottom of the arc-shaped groove.

[0014] Furthermore, a protective cover is fixedly provided on the upper end face of the housing, and a cover plate is hinged to the front of the protective cover.

[0015] Furthermore, the rotating shaft ends of the rollers all adopt a hollow tubular structure, and the pipes are galvanized pipes that extend into the rollers through the hollow rotating shaft ends.

[0016] (III) Technical Effects

[0017] Compared with existing technologies, the advantages of this invention are as follows: This device features an arc-shaped groove inside the casing, within which a rotating drum with ventilation holes is installed. The drum contains lifting plates. During drum rotation, the forage pellets are continuously lifted and agitated. Simultaneously, hot air generated by a hot air blower through a first hot air outlet on the inner wall of the arc-shaped groove and a second hot air outlet inside the drum, ensuring even contact between the hot air and each pellet. This effectively avoids the uneven drying caused by stationary or accumulated pellets in traditional drying equipment, ensuring stable drying quality of the forage pellets. The combined effect of the drum rotation and hot air accelerates the evaporation rate of moisture inside the forage pellets, improving drying efficiency. Attached Figure Description

[0032] The working principle of this drying device for grass pellet production is as follows: This device mainly utilizes a hot air blower 6 to generate hot air, which, combined with the rotation of the drum 3 and the tumbling action of the internal lifting plates 5, ensures that the grass pellets are in full contact with the hot air during the dynamic process, achieving efficient and uniform drying. Part of the hot air generated by the hot air blower 6 is transported through pipe 8 to the second hot air outlet 19 inside the drum 3, blowing the grass pellets from inside the drum 3; another part of the hot air is heated from the outside of the drum 3 through the first hot air outlet 7 on the inner wall of the arc-shaped groove 2, with both internal and external action accelerating the evaporation of moisture from the grass pellets. Simultaneously, the drum 3 continues to rotate under the drive mechanism, and the lifting plates 5 inside the drum 3 continuously lift and tumble the grass pellets, ensuring that the grass pellets are in full contact with the hot air inside the drum, guaranteeing uniform drying.

[0033] In this embodiment, as a preferred technical solution, the driving mechanism includes a motor 12 fixedly mounted on the side of the housing 1, a drive wheel 13 fixedly mounted on the drive shaft of the motor 12, and a driven wheel 14 fixedly mounted on the end of the rotating shaft of the roller 3. A belt 15 is connected between the drive wheel 13 and the driven wheel 14. The rotating shaft end of the roller 3 adopts a hollow tubular structure, and the pipe 8 adopts a galvanized pipe and extends into the roller 3 through the hollow rotating shaft end.

[0034] The working process of the drying device for grass pellet production according to this utility model is as follows:

[0035] 1. Open the cover plate 18, feed the feed pellets to be dried into the drum 3 through the feed inlet 9, and then close the cover plate 18, with the sealing door 11 in the closed state.

[0036] 2. Start the motor 12. The drive shaft of the motor 12 drives the drive wheel 13 to rotate. The drive wheel 13 drives the driven wheel 14 to rotate through the belt 15, so that the roller 3 starts to rotate in the arc groove 2.

[0037] 3. Start the hot air blower 6. Part of the hot air generated by the hot air blower 6 enters the inside of the drum 3 through the pipe 8 and the hollow shaft end of the drum 3. It blows out downward from the second hot air outlet 19 to heat and dry the feed particles inside the drum 3. The other part of the hot air blows out of the drum 3 through the first hot air outlet 7 and enters the drum 3 through the vent 4 to heat the feed particles inside the drum 3.

[0038] 4. During the rotation of the drum 3, the lifting plates 5 on its inner wall continuously lift and turn the feed pellets, so that the feed pellets come into even contact with the hot air and the moisture in the feed pellets gradually evaporates.

[0039] 5. After drying is complete, open the sealing door 11 on the discharge port 10. The drum 3 continues to rotate, and the dried feed pellets are discharged from the shell 1 through the discharge channel 16 under the action of the drum 3 rotation.

[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
