[0002] Collagen casings are made from collagen fibers from the dermis of cattle and pigs. During the preparation of collagen casings, the wet casings are shaped through drying and modification processes to become products that meet the requirements of use.
[0003] At present, the traditional collagen casing drying device adopts a wind wheel structure. The dry air drives the wind wheel to rotate, and the casing is transported on the rotating wind wheel. At the same time, the hot dry air blows towards the casing from below to modify the casing.
[0004] Since the drying air needs to drive the wind wheel while drying the casing, the utilization efficiency of the drying air is not high. At the same time, the wind wheel maintains the set speed. On the other hand, the drying air flow required for different positions of the casing on the full drying line is not consistent. When the wind wheel speed does not match the drying air flow, the wind wheel structure is difficult to simply adjust. Therefore, it is necessary to design a casing drying device that can fully utilize the drying air. Utility Model Content

[0030] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0031] Embodiment 1:
[0032] A casing drying device, comprising: Figure 1 As shown, a bellows 1, a drying tunnel 2 is arranged inside the bellows 1;
[0033] like Figure 2 As shown, a conveying chain 3 is provided on one side of the drying tunnel 2, and the conveying chain 3 moves along the length direction of the drying tunnel 2. Figure 1 As shown, the conveying chain 3 is provided with brackets 4 extending into the drying tunnel 2, and adjacent brackets 4 are spaced apart by a set distance (in this embodiment, adjacent brackets are spaced apart by 10 cm);
[0034] The bracket 4 can move along the length direction of the drying tunnel 2 with the conveying chain 3; Figure 1 As shown, the bracket 4 is located inside the drying tunnel 2, and the bracket 4 is provided with a groove opening upward, and the groove is used to fix the position of the casing 8; Figure 1 As shown, in the drying tunnel 2, the conveying chain 3 runs in the guide rail 7, and the guide rail 7 covers the upper and lower parts of the conveying chain 3. The conveying chain 3 is connected to the bracket 4 through the side opening of the guide rail 7. The setting of the guide rail 7 prevents the conveying chain 3 from sagging inside the drying tunnel 2 due to gravity, and can ensure that the heights of the brackets 4 at different positions are consistent, so that the casing 8 can be lifted and moved smoothly.
[0035] The upper surface and the lower surface of the drying tunnel 2 are respectively provided with ventilation openings 5 .
[0036] Through the above arrangement, the wind wheel structure is eliminated, which not only reduces the size of the drying tunnel 2, but also makes the overall structure more intensive and improves the utilization efficiency of the drying wind. Therefore, a fan with a small air volume can be selected, thereby reducing equipment investment and saving energy; the bracket 4 used for transmitting the casing 8 on the conveying chain 3 is also used to make the transmission speed more stable. At the same time, the moving power of the bracket 4 comes from the mechanical driving structure of the conveying chain 3, which will not occupy the wind pressure of the drying wind, making the air volume adjustment of the drying wind more flexible.
[0037] A plurality of drying tunnels 2 are arranged in the bellows 1, and the plurality of drying tunnels 2 are horizontally distributed in the bellows 1, which can realize the one-to-two or one-to-many production of collagen casings, greatly reducing the volume of the bellows 1, thereby reducing the area of the heat dissipation surface of the bellows 1, thereby reducing heat dissipation, thereby achieving the purpose of energy saving.
[0038] like Figure 2 As shown, the conveying chain 3 is driven by a driving wheel 6, and the driving wheel 6 is arranged at the starting end of the drying tunnel 2 to avoid setting a gear transmission mechanism inside the drying tunnel 2. The driving wheel 6 can also be set at the end of the drying tunnel, or a driven wheel for supporting the conveying chain 3 can be set.
[0039] The inside of the guide rail 7 is lined with polymer material to ensure that the conveyor chain 3 moves smoothly in the guide rail 7.
[0040] The guide rail 7 is fixed on the side wall of the drying tunnel 2. Since the weight of the bracket 4 and the casing 8 is relatively small, the guide rail 7 is only provided on one side of the drying tunnel 2, that is, only one side of the bracket 4 is fixed, so that the lifting effect can be achieved.
[0041] On the other hand, the side wall of the drying tunnel 2 where the guide rail 7 is not installed can be disassembled, so that the interior of the drying tunnel 2 is exposed to the side wall of the wind box 1, which is convenient for operators to adjust the internal structure of the drying tunnel 2.
[0042] like Figure 2 As shown, the bracket 4 is a flat plate structure, the plane of the flat plate is perpendicular to the length direction of the drying tunnel 2, and the groove is arranged at the upper edge of the flat plate structure. The thin flat plate structure not only reduces the weight of the bracket 4, but also avoids blocking the drying wind, thereby effectively ensuring the flow rate of the drying wind.
[0043] like Figure 1 As shown, the ventilation volume of the vents 5 of the drying tunnel 2 can be adjusted. Since the casings 8 are gradually dried and modified in the drying tunnel 2, the optimal flow rate of drying air required at different positions in the drying tunnel 2 is also different. By adjusting the flow rate of drying air at different positions, high-standard casings 8 can be produced.
[0044] like Figure 1As shown, a vent cover 9 covering the vent 5 is provided on the vent 5, and the coverage range of the vent cover 9 of the vent 5 can be adjusted. By adjusting the coverage range of the vent cover 9, the size of the vent 5 is adjusted, and then the air volume of the dry wind is adjusted.
[0045] The vent cover plate 9 is slidably connected to the upper surface or the lower surface of the drying tunnel 2, and the coverage of the cover plate can be adjusted by manually moving the cover plate.
[0046] like Figure 3 As shown, multiple drying tunnels 2 in the bellows 1 are distributed vertically, and a guide wheel set 10 is provided at the end of the drying tunnel 2. The axle of the guide wheel in the guide wheel set 10 is arranged parallel to the axle of the driving wheel 6. The guide wheel set 10 is used to guide the casing 8 in the upper drying tunnel 2 to the lower drying tunnel 2, so that the same casing 8 is transported in a circular transfer manner in the multiple vertically distributed drying tunnels 2, and the drying modification is completed in the multiple drying tunnels 2.
[0047] The guide wheel set 10 is driven, so that its rotation speed is controlled by the speed of the conveying chain 3 .
[0048] The outer edge of the guide wheel in the guide wheel assembly 10 is provided with a groove having the same shape as the groove of the bracket 4 , so as to facilitate the stable transmission of the casing 8 on the guide wheel assembly 10 .
[0049] Figure 3 In the embodiment, a single guide wheel set 10 includes one guide wheel. In actual production, one guide wheel set 10 can include multiple guide wheels to reduce the volume of the guide wheel set 10 and reduce the transfer time of the casing 8 between multiple drying tunnels 2.
[0050] When the casing drying device is in operation, the casing 8 is filled with a proper amount of gas during production, so it can maintain a cylindrical shape and enter from the starting end of the drying tunnel 2, and is lifted by the bracket 4 to move forward at a constant speed, and gradually complete the drying modification process in the drying tunnel 2; the drying air in the bellows 1 is blown into the drying tunnel 2 through the vents 5 on the lower surface of the drying tunnel 2, and is blown out from the vents 5 on the upper surface of the drying tunnel 2. Inside the drying tunnel 2, the drying air blows toward the casing 8 from below. Since the bracket 4 is in the shape of a flat plate, it will not block the drying air; when it is necessary to adjust the coverage of the vent cover 9 inside the drying tunnel 2, the side wall of the drying tunnel 2 without the guide rail 7 is removed, so that the internal structure of the drying tunnel 2 can be exposed to the outside, which is convenient for the operator to adjust and inspect the guide rail 7, the conveying chain 3 and the bracket 4.
[0051] When a protein casing drying device with a wind wheel structure is used, since multiple wind wheels rotate in situ at their respective fixed positions, rolling friction occurs between the conveyed casing and the wind wheel, driving the casing to be conveyed downstream. Therefore, the operator needs to manually guide the casing to pass through all the wind wheels one by one, and adjust it appropriately during the subsequent drying process. Since there is continuous drying wind blowing at the wind wheel position, the operator needs to manually operate at the spatial position where the high-temperature drying wind blows, which has high labor intensity. When the casing drying device of the present application is used, since the bracket and the casing move synchronously, the casing is fixed to the bracket at the entrance of the drying tunnel, and the casing produced subsequently will automatically contact with other brackets on the chain without the need for the operator to adjust them one by one; at the exit of the drying tunnel, the operator guides the casing to enter the drying tunnel below through the guide wheel to realize the transfer of the casing in multiple drying tunnels. It can be seen that in the present application, the operator only needs to manually operate at the entrance and exit positions of the drying tunnel. The blowing intensity of the drying wind at this position is low, so the temperature is lower than that at the position where the drying wind blows directly, and the operation at this position greatly reduces the labor intensity.
[0052] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
