Description

Technical Field

[0001] The utility model belongs to the technical field of food processing equipment, in particular to a continuous centrifugal dehydration device for dried fruits and preserved fruits. Background Art

[0002] During the processing of dried fruits, such as raisins, various dried plums, and various nuts, the finished dried fruits have impurities such as dust because they are not cleaned or contaminated by dust during the drying process. Therefore, they need to be cleaned to clean the dust on the surface and make the dried fruits more hygienic. The existing method of washing with running water will cause serious water accumulation on the surface of the dried fruits, especially some dried fruits with many wrinkles are prone to water accumulation. The natural drying or drying method is very inefficient.

[0003] Dehydration before drying can greatly reduce the drying time. The centrifugal device used for dehydration is a vertically installed centrifugal barrel with an open side on the upper side, which is used as both a feeding port and a discharging port. After the product is dehydrated once, it is necessary to take out the centrifugal barrel to pour out the internal material, and then add new dried fruits to be dehydrated. This repetition results in very low processing efficiency. At the same time, the continuous dumping process is likely to cause scratches on the surface of the dried fruits, which will accelerate deterioration in the later stage.

[0004] Therefore, the utility model mainly improves the discharge structure according to the working principle of the existing centrifugal dehydration device, automatically outputs the dried fruits after dehydration, realizes the continuous working process, and improves the working efficiency.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] A device for continuous centrifugal dehydration of dried fruits and preserved fruits, comprising a centrifugal barrel with an upper opening for adding the preserved fruits to be dehydrated;

[0008] The centrifugal bucket has a vertical axis and a detachable tray installed at the bottom. A motor for driving the axis of the tray to rotate is installed below the centrifugal bucket. A lifting device is installed at the bottom of the motor to control the lifting of the motor so that the tray overlaps or separates with the bottom of the centrifugal bucket.

[0009] The bottom side of the centrifugal bucket and the overlapping side of the tray are both provided with bevel teeth, and the bevel teeth corresponding to the centrifugal bucket and the bevel teeth corresponding to the tray mesh with each other for transmission when they overlap.

[0010] Furthermore, the tray is a conical structure with conical teeth on the circumferential side, and the lower opening side of the centrifugal bucket has a flared edge outwards and corresponding conical teeth.

[0011] Furthermore, the centrifugal bucket has a water leakage hole at a position corresponding to the bottom thereof, for draining the water after centrifugation.

[0012] Furthermore, it comprises a shell, the centrifugal barrel is installed with the shell, a bearing is arranged between the centrifugal barrel and the shell, and the bearing comprises inner and outer bearing rings and balls arranged inside.

[0013] A guide plate is installed at a position of the separation side of the shell corresponding to the tray and the centrifugal bucket. The guide plate is installed obliquely and is used to receive and guide the unloaded materials.

[0014] Furthermore, the lifting device includes a support plate for supporting the motor, including a cylinder assembly, the cylinder assembly is located at the lower side of the support plate and is used to drive the support plate to move up and down. A positioning rod is fixed to the circumferential side of the cylinder assembly, and the support plate has a rod sleeve for the positioning rod to pass through and telescopically cooperate with, so as to stabilize the up and down movement of the support plate.

[0015] The utility model has the following beneficial effects: the tray in the utility model serves as the bottom of the centrifugal barrel to support the preserved fruits, and the tray can rotate axially under the drive of a motor. The centrifugal barrel rotates synchronously through the meshing action of the tray and the lower side of the centrifugal barrel, so that the moisture on the surface of the preserved fruits is separated by centrifugal action.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] The centrifugal bucket 1 has a vertical axis and a detachable tray 2 is installed at the bottom. A motor 3 for driving the tray 2 to rotate is installed below the centrifugal bucket 1. A lifting device is installed at the bottom of the motor 3 to control the lifting of the motor 3 so that the tray 2 overlaps or separates with the bottom of the centrifugal bucket 1.

[0025] The bottom side of the centrifugal bucket 1 and the overlapping side of the tray are both provided with bevel teeth 21, and the bevel teeth corresponding to the centrifugal bucket 1 and the bevel teeth corresponding to the tray 2 mesh with each other for transmission when they overlap.

[0026] In the utility model, the tray serves as the bottom of the centrifugal barrel and is used to support the preserved fruits. At the same time, the tray can rotate along its axis under the drive of a motor. Through the meshing action of the tray and the lower side of the centrifugal barrel, the centrifugal barrel rotates synchronously, so that the moisture on the surface of the preserved fruits is separated by the centrifugal action. The tray and the lower side of the centrifugal barrel are designed to be detachable. When the surface of the preserved fruits is dehydrated, the tray is lowered by a lifting device and is separated from the bottom of the centrifugal barrel. The separation area is used for unloading, releasing the preserved fruits inside, preparing for the next stage of dehydration, and realizing a continuous dehydration process.

[0027] The device avoids the traditional working mode of feeding and discharging from the opening side of the centrifugal barrel at the same time, saves the tedious operation of discharging after dehydration, and improves work efficiency.

The conical teeth corresponding to the tray are meshed and installed with the conical teeth corresponding to the flared edge to improve the meshing force of synchronous rotation. The conical teeth are installed facing each other, and it is easier for the conical teeth to mesh with each other when the tray contacts the lower side of the centrifugal bucket.

[0029] The centrifugal bucket 1 has a leakage hole 12 at the corresponding bottom position, which is used to discharge the water after centrifugation. The leakage holes are opened at the bottom of the side wall of the centrifugal bucket and are arranged in a circle. It includes an outer shell 5, and the centrifugal bucket 1 is installed on the outer shell 5. There is a bearing 51 between the centrifugal bucket 1 and the outer shell 5. The bearing 51 is composed of inner and outer bearing rings and balls arranged inside. The bearing is located between the outer wall of the centrifugal bucket and the inner wall of the outer shell, and there are two of them arranged up and down. The outer shell is a square shell structure, which is used to provide support for the centrifugal bucket and provide rotation. A guide plate is installed on the outer shell 5 corresponding to the separation side of the tray 2 and the centrifugal bucket 1. The guide plate 52 is installed at an angle to receive the unloading and export it. The guide plate has a guide wall, and the guide plate is located directly below the tray.

[0030] like Figure 3 As shown: the lifting device includes a support plate 4 for supporting the motor 3, including a cylinder assembly 41, which is located at the lower side of the support plate 4 and is used to drive the support plate 4 to move up and down. A positioning rod 43 is fixed to the circumferential side of the cylinder assembly 41, and the support plate 4 has a rod sleeve 42 for the positioning rod 43 to pass through and telescopically cooperate with, which is used to stabilize the upward and downward movement of the support plate 4. The support plate movement limit is provided, and the supporting performance of the support plate is improved.
