Description

Technical Field

[0001] The invention relates to the technical field of cleaning machines, and in particular to a cleaning machine specially used for dehydrated vegetables. Background Art

[0002] Kelp is a common raw material for dehydrated vegetables, and it can maintain its unique flavor and nutrients after dehydration. Kelp is a seaweed rich in minerals, vitamins and dietary fiber, and is often used as a seasoning, soup and health food. Since kelp contains a lot of water, it is easy to store and transport for a long time after dehydration.

[0003] Traditional dehydrated vegetable washing machines can remove surface dirt and impurities to a certain extent when washing kelp, but there are still many problems and shortcomings, which are mainly manifested in the following aspects:

[0004] Uneven cleaning: When traditional dehydrated vegetable cleaning equipment processes kelp, a large amount of kelp is often stacked together, resulting in uneven cleaning.

[0005] Damage to vegetables: When processing kelp, traditional dehydrated vegetable washing equipment uses high-pressure water flow to rinse and scrub, which may cause mechanical damage to the surface of the kelp and even destroy the nutritional content and appearance of the kelp, resulting in a decline in its quality.

[0037] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0038] A washing machine specifically for dehydrated vegetables according to a preferred embodiment of the present invention will be described in detail below.

In the initial state, the axis angle between the first bracket 33 and the second bracket 35 is sixty degrees and is located on the left side of the jet pipe 31. In the working state, the first scrubbing tube 34 and the second scrubbing tube 36 are located on the right side of the jet pipe 31. Each group of cleaning devices 3 is provided with two groups of rotating devices 4 for rotating the jet pipe 31 and the sleeve 32. Two groups of fixing devices 5 for fixing kelp ropes are provided at the top of each group of cleaning devices 3. Two groups of translation devices 6 for moving the fixing devices 5 are provided on every two groups of cleaning devices 3.

[0040] During operation, when it is necessary to clean the kelp, water is injected into the cleaning box 1, and the kelp on the kelp rope is placed between the first scrubbing tube 34, the second scrubbing tube 36 and the jet tube 31, so that it is located on the right side of the first scrubbing tube 34 and the second scrubbing tube 36 and on the left side of the jet tube 31, and the two ends of the kelp rope are fixed on the fixing device 5, and the first bracket 33 and the second bracket 35 are controlled by the rotating device 4 to make the axis angle of 60 degrees and be located on the right side of the jet tube 31, and the first scrubbing tube 34 and the second scrubbing tube 36 are located on the right side of the jet tube 31, so that the kelp will change from a vertical state to an S shape, and the first scrubbing tube 34 and the second scrubbing tube 36 are similar to using two large The thumb cleans the kelp from the center to both sides. This method is gentler than brushing back and forth with a comb or rubbing with a cleaning block. In this process, the high-pressure air pump 2 works and can spray bubbles through the jet hole 37. It is easier to remove stains by breaking the bubbles, which is more uniform than flushing with high-pressure water. Subsequently, the fixing device 5 is moved by the translation device 6, and the kelp rope on the fixing device will also move accordingly.
