Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment, specifically a dehydrated food raw material processing device. Background Technology

[0002] When processing spherical or oblong fruits such as monk fruit into dehydrated foods, the fruits need to be washed to remove impurities such as mud and sand adhering to the surface of the fruit, so as to provide clean raw materials for subsequent dehydration, packaging and other processes.

[0003] One existing cleaning method involves placing the fruit into a drum, which is arranged horizontally or slightly inclined, with an inlet and an outlet at each end. The inner wall of the drum is lined with spiral blades, and a spray device is installed inside. As the drum rotates, the fruit moves along the spiral blades from the inlet to the outlet, and water is sprayed onto the fruit during this movement. However, in this process, the fruit is limited by the propulsion of the spiral blades and basically rolls forward along a regular spiral trajectory. The tumbling frequency is low, and the angle change is small, making it difficult to achieve all-around washing, resulting in a decreased cleaning effect. Utility Model Content

[0004] The purpose of this invention is to address the above problems by providing a dehydrated food raw material processing device that can improve the cleaning effect.

[0005] To achieve the above objectives, the present invention employs a dehydrated food raw material processing device, comprising a rotating drum with concentric spiral blades on its inner wall. The drum is open at both ends, serving as an inlet and outlet, respectively. The drum is housed within a casing, with drainage holes spaced apart on its inner wall and a drain hole at the bottom of the casing. A cover extends into the drum along its length, with an elongated hole at its lower part aligned with the drum's axis. A rotating shaft, also aligned with the drum's axis, rotates within this hole. A drive unit is located on the side wall of the rotating shaft, and nozzles are spaced apart on the cover, connected to a water pipe via a connecting pipe. The cover extends into the drum axially, and the outer wall of the cover defines a channel between the outer wall of the cover and the inner wall of the drum, allowing only a single layer of fruit to pass through. This inhibits longitudinal stacking of the fruit, ensuring the fruit is arranged orderly along the spiral blades and reducing rinsing dead zones. At the same time, the rotating shaft drives the drive unit to rotate, which in turn pushes the fruit inside the drum to rotate. Under the action of the rotating drum, the spiral blades, and gravity, the fruit tumbles irregularly, thereby increasing the frequency of contact between the fruit's various surfaces and the spray water flow, further eliminating cleaning dead corners and improving cleaning cleanliness.

[0006] Furthermore, a filter screen is installed inside the housing below the drum. Mud, sand, broken leaves, and other impurities falling through the drum's drainage holes are trapped by the filter screen, preventing them from clogging the drainage holes and subsequent pipelines, thus reducing maintenance frequency. It also facilitates the recycling of subsequent cleaning water.

[0007] Furthermore, the lower part of the cover at one end of the feed inlet is set as an arc-shaped section to facilitate the fruit entering between the roller and the cover.

[0008] Furthermore, the water pipe is connected to the cleaning pipe via a branch pipe, and the outlet of the cleaning pipe is located above the rotating shaft. A valve is installed on the branch pipe or the cleaning pipe; when the valve is open, cleaning water directly flushes the rotating shaft and drive unit through the outlet of the cleaning pipe to ensure effective cleaning.

[0009] Furthermore, the cover has an arc-shaped cross-section, and its smooth arc transition surface eliminates sharp edges, thus making it less likely for the fruit to get stuck during single transport and preventing damage to the fruit due to collisions with sharp edges under low speed conditions.

[0010] Furthermore, the rotation direction of the rotating shaft is opposite to the rotation direction of the drum, thus ensuring that the fruit tumbles irregularly inside the drum.

[0011] The beneficial effects of this invention are as follows: A channel is defined between the outer wall of the cover and the inner wall of the drum, allowing only a single layer of fruit to pass through. This inhibits longitudinal stacking of the fruit, ensuring that the fruit is arranged orderly along the spiral direction of the blades and reducing blind spots during rinsing. Simultaneously, the rotating shaft drives the drive unit to rotate, propelling the fruit inside the drum. This causes the fruit to tumble irregularly under the combined effects of drum rotation, spiral blade propulsion, and gravity, increasing the frequency of contact between the fruit surfaces and the sprayed water flow, further eliminating blind spots and improving the cleaning effect.

The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0016] Example 1, such as Figures 1-2As shown, the specific structure of this embodiment is a dehydrated food raw material processing device, which includes a rotating drum 1. In this embodiment, the drum 1 is horizontally arranged. The outer wall of the drum 1 is connected to the mounting hole on the housing 5 through a bearing. The housing 5 is equipped with a main motor, which is connected to the drum 1 through gears and chains. The inner wall of the drum 1 is provided with concentric spiral blades 2. The two ends of the drum 1 are open to serve as a feed inlet 3 and a discharge outlet 4, respectively. A feed guide plate is provided at the feed inlet 3, and the end of the feed guide plate that extends into the drum 1 is inclined downward.

[0017] The inner wall of the roller 1 is provided with drainage holes 6 at intervals, and all drainage holes 6 are located inside the housing 5. The lower part of the housing 5 is provided with a drain hole 7. The housing 5 is provided with a filter screen 14 below the roller, and the filter screen 14 is located above the drain hole 7. The side wall of the housing 5 is provided with an openable door to facilitate the maintenance of the filter screen 14.

[0018] The top plate of the housing 5 is provided with brackets 17 at both ends of the roller 1 along its length. The brackets 17 on both sides are fixedly connected to both ends of the cover 8 along its length. The cover 8 is located inside the roller 1. The cross-section of the cover 8 is arc-shaped. The lower part of the cover 8 at the feed inlet end is set as an arc-shaped segment 15. The cover 8 is arranged along the length of the roller 1. A gap is left between the outer wall of the cover 8 and the inner wall of the roller 1. The gap distance between the lower part of the cover and the lower part of the roller and the pitch of the spiral blade 2 are greater than the maximum outer diameter of a single fruit to be cleaned and less than twice the maximum outer diameter. The thread height of the spiral blade 2 is less than the outer diameter of a single fruit to be cleaned. The lower part of the cover 8 is provided with an elongated hole 9 in the same direction as the cover. A rotating shaft 10 in the same direction is provided in the elongated hole 9. The rotating shaft 10 is connected to an auxiliary motor through gears, etc. The auxiliary motor is located inside the cover 8. The auxiliary motor drives the rotating shaft 10 to rotate around its axis. The rotation direction of the rotating shaft 10 is opposite to the rotation direction of the roller 1. A drive part 11 is provided on the side wall of the rotating shaft 10. The drive part 11 is made of flexible materials such as silicone. Multiple nozzles 12 are provided on the cover 8. The nozzles 12 are arranged along the length of the roller 1. The nozzles 12 are connected to a water pipe 13 through a connecting pipe. One end of the water pipe 13 extends out of the cover 8 and is connected to a water source.

[0019] The water pipe 13 is connected to the cleaning pipe 16 via a branch pipe, and a valve is installed on the branch pipe. The outlet of the cleaning pipe 16 is located above the rotating shaft 10.

[0020] The specific cleaning process is as follows: The fruit enters the drum 1 through the feed inlet 3; the lower front end of the cover 8 is arc-shaped, and the fruit slides along this arc-shaped section between the cover 8 and the inner wall of the drum 1. As the drum 1 rotates, the fruit is arranged in a single layer along the spiral direction of the spiral blades 2 under the action of the spiral blades 2 and moves towards the discharge port 4. During the movement of the fruit, the drive unit 11 rotates with the rotating shaft 10; when the drive unit 11 is below the rotating shaft 10, the lower part of the drive unit 11 contacts the upper surface of the fruit. As the drive unit 11 continues to rotate, it pushes the fruit to tumble irregularly inside the drum 1; at the same time, water from the water source is pumped through the water pipe 13 to the nozzle 12, and the nozzle 12 sprays a water curtain to rinse the fruit from all directions.

[0021] After rinsing, the water enters the housing 5 through the drain hole 6, is filtered by the filter screen 14, and is discharged through the drain hole 7. When the drive unit 11 needs to be cleaned, the valve on the branch pipe is opened, and the water in the water pipe 13 directly rinses the rotating shaft 10 and the drive unit 11 through the outlet of the cleaning pipe 16. The rinsing water is also filtered by the filter screen 14 and then discharged.
