Description

Technical Field

[0001] This utility model relates to the field of food processing drying technology, specifically a rotary air dryer. Background Technology

[0002] Food processing refers to the processing of grains, feed, vegetable oils and sugars, slaughtering and meat processing, aquatic products, and other foods such as vegetables, fruits and nuts, as well as tuber processing, dehydrated vegetable processing, and canned vegetable processing, which are all carried out directly using agricultural, forestry, animal husbandry and fishery products as raw materials. It is a type of agricultural product processing industry in a broad sense. In the process of food processing, food needs to be dried, so rotary drying equipment is required.

[0003] In the process of rotary drying of food, the food is usually placed inside a turntable and rotated. Then, a blower blows air onto the sides of the turntable to dry the food inside. As a result, the blower can only dry food on the sides of the turntable, and the drying effect is poor for food placed inside the turntable. Therefore, it takes a long time to dry food in the middle of the turntable, resulting in low drying efficiency.

[0004] When food is placed inside the turntable for drying, the rotation of the turntable causes the food in the center to move to the side of the turntable due to rotational inertia. This causes the food to be squeezed together during rotation, resulting in poor drying of the food in the center and affecting the drying process of the food that has moved to the side of the turntable.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5This utility model provides a technical solution: a rotary air dryer, including a housing 1, with brackets 14 installed on both the left and right sides of the housing 1. The cross-section of the brackets 14 is annular. A first reduction motor 15 is bolted to the outer side of the brackets 14, causing the first reduction motor 15 to move clockwise. The output end of the first reduction motor 15 passes through the brackets 14 and is welded to a first gear 16, which drives the first gear 16 to move clockwise. A second gear 18 meshes with the outer wall of the first gear 16, driving the second gear 18 to move counterclockwise. The transmission ratio between the first gear 16 and the second gear 18 is 1:2. There are four second gears 18, which are evenly distributed around the outer wall of the first gear 16. A rotating shaft 17 is fixedly connected to the center of the second gear 18, and the left and right sides of the rotating shaft 17 are axially connected to the outer wall of the bracket 14. Next, a first blade is installed on the inner side of the first gear 16. The first gear 16 drives the first blade to move clockwise. A second blade 19 is installed on the inner side of the second gear 18. The second gear 18 drives the second blade 19 to rotate clockwise. A filter screen 6 is installed in the inner cavity of the bracket 14. A second geared motor 2 is bolted to the front side of the housing 1. The second geared motor 2 is started, causing it to rotate clockwise. A lead screw 3 is installed through the housing 1 at the output end of the second geared motor 2. The second geared motor 2 drives the lead screw 3 to rotate clockwise. The threads on the outer walls of the front and rear ends of the lead screw 3 rotate in opposite directions. A sliding plate 5 is screwed to the outer wall of the lead screw 3 through a threaded hole. The clockwise rotation of the lead screw 3 drives the two sliding plates 5 to move inward. When the two sliding plates 5 move inward to a suitable position, the second geared motor 2 stops. A clamping device is provided at the bottom end of the sliding plate 5.

[0028] As a preferred embodiment, the clamping device further includes a third geared motor 20, a rectangular block 7, a fourth geared motor 8, a third gear 9, a fourth gear 10, a fifth gear 11, a gripper 12, and a rotating rod 13.

[0029] A third reduction motor 20 is fixedly connected to the bottom end of the sliding plate 5. When the third reduction motor 20 is started, a rectangular block 7 is fixedly connected to its output end. The third reduction motor 20 drives the rectangular block 7 to rotate clockwise, thereby causing the item to rotate clockwise. A fourth reduction motor 8 is bolted to the outer bottom end of the rectangular block 7. When the fourth reduction motor 8 is started, a third gear 9 is welded through the rectangular block 7 to its output end. The clockwise rotation of the fourth reduction motor 8 drives the third gear 9 to rotate clockwise. One side of the outer wall of the third gear 9 is engaged with... The fourth gear 10 is driven by the third gear 9 to rotate counterclockwise. The fifth gear 11 meshes with the rear outer wall of the fourth gear 10, and the fourth gear 10 drives the fifth gear 11 to rotate clockwise. The front end of the fourth gear 10 and the rear end of the fifth gear 11 are both welded with grippers 12. The grippers 12 are formed by connecting a horizontal bar and a vertical bar. The inner side of the grippers 12 is pasted with a rubber pad. The grippers 12 move inward to clamp the item. The inner side of the grippers 12 is connected to one end of a rotating rod 13, and the other end of the rotating rod 13 is connected to the top outer wall of the rectangular block 7.

[0030] As a preferred option, the front and rear ends of the housing 1 are both axially connected to doors, which facilitate the placement of items inside the device.

[0031] As a preferred option, the top of the housing 1 is provided with a sliding groove 4, and there are two sliding plates 5, which are evenly and symmetrically distributed on the outer walls of the front and rear ends of the lead screw 3. The lead screw 3 rotates clockwise to drive the two sliding plates 5 to move inward. When the two sliding plates 5 move inward to the appropriate position, the second reduction motor 2 stops.

[0032] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0033] In use, start the second reduction motor 2, causing it to rotate clockwise. The second reduction motor 2 drives the lead screw 3 to rotate clockwise, which in turn moves the two sliding plates 5 inwards. When the two sliding plates 5 reach the desired position, stop the second reduction motor 2. Then, start the fourth reduction motor 8. The fourth reduction motor 8 rotates clockwise, driving the third gear 9 to rotate clockwise. The third gear 9 then drives the fourth gear 10 to rotate counter-clockwise, and the fourth gear 10 drives the fifth gear 11 to rotate clockwise. At this point, the gripper 12 moves inwards to clamp the item. When the third geared motor 20 is activated, it drives the rectangular block 7 to rotate clockwise, which in turn drives the item to rotate clockwise. This causes the first geared motor 15 to move clockwise, which in turn drives the first gear 16 to move clockwise. The first gear 16 then drives the second gear 18 to move counterclockwise, which in turn drives the first blade to move clockwise. At the same time, the second gear 18 drives the second blade 19 to rotate clockwise, effectively allowing air to circulate inside the housing 1 and effectively and quickly drying the item. This design has a simple structure, obvious beneficial effects, and strong applicability.
