[0035] The working principle of this specific implementation method:

[0036] 1. The washed vegetables are conveyed to the top of the cylinder 1 by a conveyor, and are placed in the dehydration cylinder 5-6 by the space between the top plate 5-1 and the upper end of the cylinder 1 fixed by a motor. The vegetables are then put into the dehydration cylinder 5-6, and the dehydration motor 5-2 is started. The dehydration motor 5-2 drives the dehydration cylinder 5-6 to rotate, and the water entrained in the vegetables in the dehydration cylinder 5-6 is thrown out by the net cylinder 5-6-1, and slides down along the inner wall of the cylinder 1 to the space formed between the outer wall of the conical plate cylinder 5-6-2 and the inner wall of the conical lower end of the lower end of the cylinder 1. The liquid level controller 5-10 senses the liquid level of the accumulated water in the space. When the liquid level exceeds the set value, the liquid drain valve 5-9 is controlled to open to discharge the accumulated water.

[0037] 2. After dehydration, the discharge valve 5-7 is in an open state. After dehydration, the vegetables enter the discharge barrel 1-1 through the discharge valve 5-7, and are diverted to the inner ports of the two feeder housings 4-1 by the conical guide plate 6 in the discharge barrel 1-1, and are transported to the outer port of the feeder housing 4-1 by the started and running feeder mesh belt 4-4 to enter the next process. During transportation, due to the presence of the mesh holes in the feeder mesh belt 4-4, the moisture remaining on the vegetables is drained due to gravity.

[0038] After adopting the above structure, the beneficial effects of this specific implementation are:

[0039] 1. The dehydration cylinder can be used to dehydrate the vegetables after washing, so as to avoid excessive water from entering the next process and improve the work efficiency of the next process;

[0040] 2. The discharge valves 5-7 are selectively opened and closed according to the required dehydration requirements. When in the normally open state, the vegetables are dehydrated and transported at the same time, and the dehydration degree is low. When in the closed state, the dehydration degree is high, and the vegetables are transported after dehydration, which increases its application range;

[0041] 3. The conveying mesh belt 4 can be used to drain the residual water in the vegetables again. If the washed vegetables do not need to be dehydrated, the dehydration motor 5-2 can be turned off, and the vegetables can be directly conveyed to the conveying mechanism 4 through the cylinder 1, and the conveying mesh belt 4-4 in the conveying mechanism 4 will drain the water; increase the scope of application;

[0042] 4. The setting of the ventilation mechanism 9 can further ventilate and naturally dry the vegetables during the transportation process to remove moisture, thereby effectively increasing the moisture removal efficiency.

[0043] The above description is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
