Description

Technical Field

[0001] The utility model relates to the technical field of food processing equipment, in particular to a centrifugal drying device. Background Art

[0002] When freeze-dried foods are processed, the ice sublimation method is mostly used to obtain the freeze-dried foods. However, when processing some fruit and vegetable foods, it is very difficult to sublimate water molecules. Therefore, a centrifuge is needed to assist in dehydrating and drying the foods.

[0003] For example, the patent with the application number 202220627350.0 discloses a centrifugal drying device for a food freeze dryer. In order to facilitate the removal of the dehydrated and dried foods outwards, the rotating cylinder of the above centrifuge is set to be a structure that can be flipped. However, because the centrifugal force during the operation of the rotating cylinder is relatively large, the flipping structure is very prone to looseness, causing damage to the centrifuge. Moreover, when the rotating cylinder is flipped and the foods are poured outwards, some foods will also adhere to the inner wall of the rotating cylinder, and the cleaning is not thorough, and manual cleaning is still required. Summary of the Invention

[0004] The utility model provides a centrifugal drying device, which is more stable and not easily damaged during use, and can also push the foods on the inner wall of the centrifugal cylinder upwards when pushing out the foods, without manual cleaning of the inner wall of the centrifugal cylinder.

[0005] In the first aspect of the present disclosure, a centrifugal drying device is provided, which specifically includes: a dryer housing;

[0006] Two centrifugal cylinder supports are arranged inside the dryer housing; a centrifugal cylinder is rotatably installed inside the two centrifugal cylinder supports; an inner support plate is slidably installed inside the centrifugal cylinder; a multi-stage electric cylinder is installed at the middle position of the inner bottom of the dryer housing; a motor is also installed at the inner bottom of the dryer housing, and the gear at the top end of the motor spindle meshes with the toothed ring on the outer side of the centrifugal cylinder; a discharge baffle is welded to the top of the dryer housing; a pushing plate is slidably installed inside the discharge baffle.

[0007] In at least some embodiments, the top surface of the centrifugal cylinder is in the same plane as the top surface of the dryer housing. When the inner support plate moves up to the topmost position, the top surface of the inner support plate will also be in the same plane as the top surface of the dryer housing.

[0008] In at least some embodiments, two annular protrusions are provided on the outer wall of the centrifugal cylinder, and an annular groove corresponding to the size of the annular protrusion on the outer wall of the centrifugal cylinder is also provided inside each of the centrifugal cylinder supports.

[0009] In at least some embodiments, an L-shaped plate is provided on the front and rear sides of the top of the push plate, and a long strip opening is provided on the front and rear sides of the discharge baffle. The L-shaped plates on the front and rear sides of the top of the push plate can slide left and right in the long strip openings on the front and rear sides of the discharge baffle, and the bottom outer wall of the push plate is also tightly attached to the top outer wall of the dryer casing.

[0010] In at least some embodiments, the outer wall of the centrifuge barrel is provided with a plurality of vertical open grooves extending inside and outside in a circular arrangement, the outer diameter of the inner support plate is equal to the inner diameter of the centrifuge barrel, and the outer side of the inner support plate is also provided with a plurality of rectangular raised blocks arranged in a circular arrangement, and the rectangular raised blocks on the outer side of the inner support plate can also slide up and down in the vertical open grooves on the outer wall of the centrifuge barrel.

[0011] In at least some embodiments, the discharge baffle is a U-shaped plate with an opening on the right side, and the top and bottom of the vertical opening groove on the outer wall of the centrifuge cylinder are both closed structures.

[0012] In at least some embodiments, a circular plate is disposed at the top of the multi-section electric cylinder.

[0013] The utility model provides a centrifugal drying device, which has the following beneficial effects:

[0014] An inner supporting plate for supporting food is installed on the inner side of the centrifugal drum in the utility model. When the food is dehydrated and dried, the inner supporting plate is located on the inner side of the bottom of the centrifugal drum. When the dehydration and drying is completed and the food needs to be taken out, the inner supporting plate can be pushed to the top by a multi-section electric cylinder, and then the food can be pushed out upward. The drying equipment is more stable and not easy to be damaged during use, and when the food is pushed out, the food on the inner wall of the centrifugal drum can also be pushed upward at the same time, without the need to manually clean the inner wall of the centrifugal drum.

Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Embodiment 1: Please refer to Figures 1 to 6 :

[0028] The present utility model provides a centrifugal drying device, comprising: a dryer housing 1;

[0029] Inside the dryer housing 1, there are two centrifuge cylinder support frames 2. The dryer housing 1 is used to support the structures inside and on top of it, and the centrifuge cylinder support frame 2 is used to rotationally support the centrifuge cylinder 3. Inside the two centrifuge cylinder support frames 2, a centrifuge cylinder 3 is rotatably installed. The centrifuge cylinder 3 is used to hold the food that needs to be dehydrated and dried. Inside the centrifuge cylinder 3, an inner support plate 4 is slidably installed. The inner support plate 4 is used to support the food that needs to be dehydrated and dried, and when the inner support plate 4 slides upward, it can push the dried food in the centrifuge cylinder 3 upward. In the middle position of the inner bottom of the dryer housing 1, a multi-stage electric cylinder 5 is installed. The multi-stage electric cylinder 5 is used to push the inner support plate 4 upward. Inside the bottom of the dryer housing 1, a motor 6 is also installed, and the gear at the top of the main shaft of the motor 6 meshes with the toothed ring on the outer side of the centrifuge cylinder 3. When the motor 6 rotates, it will drive the centrifuge cylinder 3 to rotate at high speed under the support of the centrifuge cylinder support frame 2 through the gear at the top of its main shaft. A discharge baffle 7 is welded to the top of the dryer housing 1. The discharge baffle 7 is used to support the push plate 8. Inside the discharge baffle 7, a push plate 8 is slidably installed. When the inner support plate 4 moves up to the top, all the food will be above the top surface of the dryer housing 1. At this time, the push plate 8 can be pushed to the right inside the discharge baffle 7, and then the dried food can be pushed out through the opening on the right side of the discharge baffle 7.

[0030] In the embodiment of the present disclosure, as Figure 2 and Figure 4 shown, the top surface of the centrifuge cylinder 3 is on the same plane as the top surface of the dryer housing 1. When the inner support plate 4 moves up to the top, the top surface of the inner support plate 4 will also be on the same plane as the top surface of the dryer housing 1. When the inner support plate 4 moves up to the top, all the food will be above the top surface of the dryer housing 1. At this time, the push plate 8 can be pushed to the right inside the discharge baffle 7, and then the dried food can be pushed out through the opening on the right side of the discharge baffle 7.

[0031] In the embodiment of the present disclosure, as Figures 3 to 6 shown, there are two annular protrusions on the outer wall of the centrifuge cylinder 3, and there is also an annular groove corresponding to the annular protrusion on the outer wall of the centrifuge cylinder 3 on the inner side of the centrifuge cylinder support frame 2. When the motor 6 rotates, it will drive the centrifuge cylinder 3 to rotate at high speed under the support of the centrifuge cylinder support frame 2 through the gear at the top of its main shaft. At this time, the moisture on the food in the centrifuge cylinder 3 will be thrown out through the vertical opening grooves on the outer wall of the centrifuge cylinder 3 due to the centrifugal force and enter the cavity inside the dryer housing 1.

[0032] In the embodiment of the present disclosure, as Figures 1 to 4As shown, an L-shaped plate is provided on the front and rear sides of the top of the push plate 8, and a long strip opening is provided on the front and rear sides of the discharge baffle 7. The L-shaped plates on the front and rear sides of the top of the push plate 8 can slide left and right in the long strip openings on the front and rear sides of the discharge baffle 7, and the bottom outer wall of the push plate 8 is also tightly attached to the top outer wall of the dryer housing 1, thereby ensuring the stability of the push plate 8 when sliding left and right.

[0033] In the present disclosure, Figures 1 to 4 and Figure 6 As shown, a plurality of vertical opening grooves penetrating inside and outside are arranged in a ring shape on the outer wall of the centrifugal cylinder 3, the outer diameter of the inner support plate 4 is equal to the inner diameter of the centrifugal cylinder 3, and a plurality of rectangular protrusions are also arranged in a ring shape on the outer side of the inner support plate 4, and the rectangular protrusions on the outer side of the inner support plate 4 can also slide up and down in the vertical opening grooves on the outer wall of the centrifugal cylinder 3. When drying, the moisture on the food in the centrifugal cylinder 3 will be thrown outward through the vertical opening grooves on the outer wall of the centrifugal cylinder 3 due to the centrifugal force and enter the cavity inside the dryer housing 1, and the inner support plate 4 can slide upward to push the dried food in the centrifugal cylinder 3 upward, and the rectangular protrusions on the outer side of the inner support plate 4 can also clean the vertical opening grooves on the outer wall of the centrifugal cylinder 3.

[0034] In the present disclosure, Figure 3 As shown, a circular plate is provided at the top of the multi-section electric cylinder 5. When the multi-section electric cylinder 5 is retracted to its shortest state and the inner support plate 4 is moved down to the bottom, the circular plate at the top of the multi-section electric cylinder 5 will be located below the inner support plate 4. When the device is needed to dehydrate and dry food, the multi-section electric cylinder 5 is first controlled to retract to the shortest state, and then the inner support plate 4 can be pressed down to the bottom. Moreover, after the inner support plate 4 is moved down to the bottom, it will not contact the circular plate at the top of the multi-section electric cylinder 5. Therefore, when the centrifugal cylinder 3 and the inner support plate 4 rotate, no friction will be generated with the circular plate at the top of the multi-section electric cylinder 5.

[0035] Embodiment 2, based on embodiment 1, as Figures 1 to 6 As shown, the discharge baffle 7 is a U-shaped plate with an opening on the right side, and the top and bottom of the vertical opening groove on the outer wall of the centrifugal cylinder 3 are both closed structures. When the inner support plate 4 moves to the top, all the food will be located above the top surface of the dryer housing 1. At this time, the push plate 8 can be pushed to the right on the inner side of the discharge baffle 7, and then the dried food can be pushed out through the opening on the right side of the discharge baffle 7, and the inner support plate 4 will not be separated from the centrifugal cylinder 3 when sliding up and down.

[0036] Working principle of this embodiment: When it is necessary to use this device to dehydrate and dry food, first control the multi-stage electric cylinder 5 to contract to the shortest state, and then the inner support plate 4 can be pressed down to the bottom. Moreover, after the inner support plate 4 moves down to the bottom, it will not contact the circular plate at the top of the multi-stage electric cylinder 5. Therefore, when the centrifugal cylinder 3 and the inner support plate 4 rotate, they will not rub against the circular plate at the top of the multi-stage electric cylinder 5. Then, put the food to be dehydrated into the inside of the centrifugal cylinder 3 through the opening at the top of the centrifugal cylinder 3. After placing the food, control the motor 6 to rotate. When the motor 6 rotates, it will drive the centrifugal cylinder 3 to rotate at high speed under the support of the centrifugal cylinder support frame 2 through the gear at the top of its main shaft. At this time, the moisture on the food in the centrifugal cylinder 3 will be thrown outwards through the vertical opening grooves on the outer wall of the centrifugal cylinder 3 due to centrifugal force and enter the cavity inside the dryer housing 1. Finally, this water will be discharged outwards through the opening at the bottom left of the dryer housing 1. After the food is dehydrated and dried, stop the rotation of the motor 6, and then control the multi-stage electric cylinder 5 to extend to push the circular plate at its top upwards. During this process, the circular plate will contact the bottom surface of the inner support plate 4 and push the inner support plate 4 to slide upwards. When the inner support plate 4 slides upwards, it will push the dried food in the centrifugal cylinder 3 upwards. Moreover, the rectangular raised blocks on the outside of the inner support plate 4 can also clean the vertical opening grooves on the outer wall of the centrifugal cylinder 3. When the inner support plate 4 moves up to the top, all the food will be above the top surface of the dryer housing 1. At this time, the push plate 8 can be pushed to the right inside the discharge baffle 7, and then the dried food can be pushed outwards through the opening on the right side of the discharge baffle 7.
