Description

Technical Field

[0001] This utility model relates to the field of equipment for extracting collagen from pig skin, and in particular to a low-temperature rotary drum. Background Technology

[0002] In the process of preparing collagen extraction from pigskin, the pigskin needs to be cleaned and degreased. Currently, this process is usually carried out using a rotary drum machine. During the degreasing process, a low temperature needs to be maintained to avoid the pigskin being unusable for subsequent processes and collagen extraction. However, the existing rotary drum technology has some shortcomings in temperature control, making it difficult to maintain a suitable temperature. In addition, after degreasing, a certain amount of moisture remains on the surface of the pigskin, which will affect subsequent processing. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this invention provides a low-temperature drum that can effectively maintain the temperature inside the drum and ensure the degreasing effect.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a low-temperature rotating drum, including a fixed outer cylinder, in which an inner rotating cylinder is provided; the fixed outer cylinder is provided with symmetrically arranged outer cylinder windows, and an outer cylinder cover plate is provided on the outer cylinder windows; a drain outlet is provided at the bottom of the fixed outer cylinder; the inner rotating cylinder is provided with an inner layer window, and an inner layer cover plate is provided on the inner layer window; the inner rotating cylinder is also provided with several neatly arranged through holes; a drive shaft and a hollow shaft are respectively provided on both sides of the inner rotating cylinder; three sets of flipping ribs and three flaps are evenly arranged inside the inner rotating cylinder; the flipping ribs and flaps are staggered; and a refrigeration pipe is provided in the flipping ribs.

[0005] Preferably, the outer cylinder cover includes a sliding cover and a fixed slide rail. The fixed slide rail is disposed on the fixed outer cylinder, and the sliding cover is disposed on the fixed outer cylinder via the fixed slide rail. L-shaped limiting plates are provided at both ends of the sliding cover, and limiting strips that cooperate with the limiting plates are provided on the fixed slide rail. Several drainage holes are also provided at one end of the sliding cover. The outer cylinder cover has the same structure as the inner cover.

[0006] Preferably, the outer cylinder window and the inner layer window are provided with sealing strips along their edges.

[0007] Preferably, the inner rotating cylinder has transparent observation plates on both sides, and the fixed outer cylinder has multiple observation windows on both sides.

[0008] The beneficial effects of this invention are that by fixing the outer cylinder and the inner rotating cylinder in layers, the temperature exchange between the internal low-temperature water and the outside can be reduced, the heating rate of the water in the inner rotating cylinder can be reduced, and the water temperature can be continuously and stably reduced through the setting of the cooling pipe, which can effectively control the temperature during the degreasing process of pigskin; after degreasing, the rotation of the inner rotating cylinder and the through holes can effectively remove the moisture from the surface of the pigskin, which provides convenience for subsequent processing and improves the overall production efficiency.

[0017] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0018] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0019] according to Figures 1-6As shown, a low-temperature rotating drum includes a fixed outer cylinder 1, which provides insulation and reduces temperature exchange between the internal low-temperature water and the outside environment. An inner rotating cylinder 2 is disposed within the fixed outer cylinder 1 to hold pigskin for degreasing. Symmetrically arranged outer cylinder windows 3 are provided on the fixed outer cylinder 1, allowing users to easily locate and open the corresponding outer cylinder window 3 before or after degreasing, regardless of the orientation of the inner rotating cylinder 21, for placing and removing the pigskin. An outer cylinder cover plate 4 is provided on each outer cylinder window 3. A drain outlet 5 is provided at the bottom of the fixed outer cylinder 1, which, when opened, drains water from the fixed outer cylinder 1. An inner rotating cylinder 2 has an inner window 21, and an inner cover plate 22 is provided on each inner window 21. The inner rotating drum 2 is also provided with several neatly arranged through holes 23 for connecting and fixing the outer drum 1 and the inner rotating drum 2. The inner rotating drum 2 is also provided with a drive shaft 28 and a hollow shaft 29 on both sides respectively. Three sets of turning ribs 24 and three flip plates 25 are evenly arranged inside the inner rotating drum 2. The turning ribs 24 and flip plates 25 are arranged alternately. The turning ribs 24 and flip plates 25 can turn the pigskin placed in the inner rotating drum 2 during the degreasing process to ensure the degreasing effect. The turning ribs 24 are provided with a cooling pipe 26, which can cool the water in the inner rotating drum 2 to ensure the temperature stability during the degreasing process. The cooling pipe 26 is arranged in the inner rotating drum 2. The refrigerant in the cooling pipe 26 is connected to the outside at the position of the hollow shaft 29 for exchange.

[0020] The outer cylinder cover 4 includes a sliding cover 41 and a fixed slide rail 42. The fixed slide rail 42 is mounted on the fixed outer cylinder 1, and the sliding cover 41 is mounted on the fixed outer cylinder 1 via the fixed slide rail 42. The sliding cover 41 can slide along the fixed slide rail 42, allowing the user to easily open or close the cover for easy insertion and removal of pigskin. L-shaped limiting plates 43 are provided at both ends of the sliding cover 41, and limiting strips 44 that cooperate with the limiting plates 43 are provided on the fixed slide rail 42. The limiting plates 43 and the limiting strips 44 cooperate with each other to limit the extreme positions of the opening and closing of the cover. Several drainage holes 45 are also provided at one end of the sliding cover 41. The outer cylinder cover 4 has the same structure as the inner cover 22.

[0021] The outer cylinder window 3 and the inner layer window 21 are provided with sealing strips 6. The sealing strips 6 can ensure the sealing of the outer cylinder 1 after the outer cylinder cover plate 4 is closed.

[0022] The inner rotating cylinder 2 has transparent observation plates 46 on both sides, and the fixed outer cylinder 1 has multiple observation windows 7 on both sides. The interior of the inner rotating cylinder 2 can be observed during the degreasing process through the observation windows 7 and the observation plates 46.

[0023] In practical use, the fixed outer cylinder 1 and the inner rotating cylinder 2 are fixed to the support base by the drive shaft 28 and the hollow shaft 29. The drive shaft 28 is connected to the drive motor to drive the rotation of the inner rotating cylinder 2, while the hollow shaft 29 is connected to the water inlet pipe and the cooling pipe 26 to inject water into the inner rotating cylinder 2. When in use, first open the outer cylinder cover plate 4 and the inner cover plate 22, place the pigskin to be degreased in the inner rotating cylinder 2, then close the outer cylinder cover plate 4 and the inner cover plate 22, start the drive motor to make the inner rotating cylinder 2 start to rotate. During the degreasing process, the cooling pipe 26 in the flipping rib 24 cools the water, while the fixed outer cylinder 1 effectively reduces heat exchange, thereby ensuring the temperature stability during the degreasing process. After degreasing is completed, open the drain hole 45 to drain the water in the inner rotating cylinder 2. Then, the inner rotating cylinder 2 continues to rotate, using centrifugal force to throw the water attached to the pigskin into the fixed outer cylinder 1 and drain it through the drain hole 45.

[0024] This design is ingenious. By using a fixed outer cylinder and an inner rotating cylinder in a layered configuration, it reduces the temperature exchange between the internal low-temperature water and the outside environment, thus slowing down the temperature rise of the water in the inner rotating cylinder 2. The water temperature is continuously and stably reduced through the setting of the refrigeration pipe, which can effectively control the temperature during the degreasing process of pigskin. After degreasing, the rotation of the inner rotating cylinder and the through holes can effectively remove moisture from the surface of the pigskin, providing convenience for subsequent processing steps and improving overall production efficiency.

[0025] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
