Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cleaning equipment, specifically a processing system for dehydrated food. 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 processing system for dehydrated food that can improve the cleaning effect.
[0005] To achieve the above objectives, the present invention employs a processing system for dehydrated food, comprising a washing cylinder open at both ends with drainage holes on its side walls. A screw, co-oriented with the cylinder, rotates around its axis inside the washing cylinder. An elongated hole is provided on the side wall of the washing cylinder, within which a rotating shaft, also co-oriented with the cylinder, rotates around its axis. A drive unit is located on the side wall of the rotating shaft. A spray nozzle is also provided on the side wall of the washing cylinder. The inner wall of the washing cylinder and the screw define a channel for a single layer of fruit to pass through, thus preventing longitudinal stacking of the fruit and ensuring an orderly arrangement of the fruit along the screw's thread direction, reducing cleaning dead zones. Simultaneously, the rotating shaft drives the drive unit to rotate, propelling the fruit inside the washing cylinder. This causes the fruit to tumble irregularly under the combined effects of the screw's propulsion, the drive unit's push, and gravity, increasing the contact frequency between the fruit's surfaces and the sprayed water flow, further eliminating cleaning dead zones and improving cleaning cleanliness.
[0006] Furthermore, the outer wall of the screw is provided with bristles. The flexible bristles replace the rigid metal screw and make direct contact with the fruit, reducing the phenomenon of fruit peel scratches. The bristles form a flexible contact with the fruit skin, increasing friction and causing the fruit to rotate during the screw's advancement, thereby improving the rinsing coverage. At the same time, the bristles scrub the fruit to improve the cleaning effect.
[0007] Furthermore, the cleaning cylinder is mounted on the housing, the drain holes are located inside the housing, and a drain outlet is provided at the bottom of the housing. The housing encloses all the drain holes, thus preventing water and impurities generated during rinsing from leaking out and maintaining a clean working environment.
[0008] Furthermore, a filter screen is installed inside the housing below the cleaning cylinder. Water filtered by the filter screen flows to a water source, realizing water recycling.
[0009] The beneficial effects of this invention are as follows: The inner wall of the washing cylinder and the screw define a channel for only a single layer of fruit to pass through, thereby preventing fruit from piling up and ensuring that the fruit is arranged in an orderly manner along the screw thread direction, reducing blind spots during rinsing. At the same time, the rotating shaft drives the drive unit to rotate, which in turn pushes the fruit inside the washing cylinder to rotate. Under the action of screw propulsion, drive unit pushing, and gravity, the fruit tumbles irregularly, thereby increasing the contact frequency between the fruit surfaces and the sprayed water flow, further eliminating blind spots during rinsing and improving the cleanliness of the washing process.

[0013] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. 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.
[0014] Example 1, such as Figures 1-2As shown, the specific structure of this embodiment is a processing system for dehydrated food. It includes a washing cylinder 1, which is open at both ends. One end serves as the inlet and the other end as the outlet. The washing cylinder 1 is horizontally or inclined. When inclined, the inlet is higher than the outlet. Drain holes 2 and nozzles 7 are spaced apart on the side wall of the washing cylinder 1. The outlet of the nozzle 7 is located inside the washing cylinder 1, and the outlet face of the nozzle 7 is flush with or lower than the inner wall of the washing cylinder 1. The outer end of the nozzle 7 is connected to a water source through a water pipe so that water from the water source can be sprayed into the washing cylinder through the nozzle 7 under the action of a water pump, thereby washing the fruit inside the washing cylinder 1. The cleaning cylinder 1 is installed on the mounting hole of the housing 8, so that both ends of the cleaning cylinder 1 are open. All the drain holes 2 are located inside the housing 8. A drain outlet 9 is provided at the lower part of the housing 8. A filter screen 10 is provided inside the housing 8 below the cleaning cylinder 1. The filter screen 10 is located above the drain outlet 9. An openable door is provided on the side wall of the housing 8 to facilitate the maintenance of the filter screen 10.
[0015] The cleaning cylinder 1 contains a screw 3 aligned with it. The distance between the outer diameter of the screw 3 and the inner wall of the cleaning cylinder 1 is smaller than the outer diameter of a single fruit, and the distance between the inner diameter of the screw 3 and the inner wall of the cleaning cylinder 1 is less than twice the outer diameter of a single fruit. Brush bristles are provided on the outer wall of the screw 3. Rotating shafts are located at both ends of the screw 3, and these shafts are connected to a support frame. The support frame is fixedly mounted on the housing 8, and one end of the rotating shaft is connected to a main motor on the support frame.
[0016] The cleaning cylinder 1 has an elongated hole 4 on its side wall. In this embodiment, the elongated hole 4 is located below the screw 3. A rotating shaft 5 in the same direction as the screw 3 is installed in the elongated hole 4. An auxiliary motor is installed on the outer wall of the cleaning cylinder 1 or the housing 8. The output shaft of the auxiliary motor is connected to the rotating shaft 5 through gears, belts, etc. The rotating shaft 5 rotates around its axis under the drive of the auxiliary motor. A drive unit 6 is installed on the side wall of the rotating shaft 5.
[0017] The specific cleaning process is as follows: The fruit enters the cleaning cylinder 1 through the feed inlet; the screw 3 has tapered ends, and the fruit enters between the screw 3 and the cleaning cylinder 1. As the screw 3 rotates, the fruit moves towards the discharge outlet in a single layer under the action of the screw threads. During the movement of the fruit, the drive unit 6 rotates with the rotating shaft 5; when the drive unit 6 is above the rotating shaft 5, the upper part of the drive unit 6 extends out of the cleaning cylinder 1 and contacts the surface of the fruit. As the drive unit 6 continues to rotate, it pushes the fruit to tumble irregularly inside the cleaning cylinder 1; at the same time, water from the water source is pumped to the nozzle 7, and the nozzle 7 sprays a water curtain to rinse the fruit from all directions.
[0018] After rinsing, the water enters the housing 8 through the drain hole 2, is filtered by the filter screen 10, and is discharged through the drain outlet 9.
[0019] The present invention has been described in detail above with reference to the embodiments. However, the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of implementation of the present invention. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the protection scope of the present invention.
