In the above-mentioned conventional one-tank vegetable washing apparatus, since all washing is performed in one tank, dirty water and fresh water are mixed in the tank, and the exchange of washing water is insufficient. ,
There is a problem that complete and clean washing cannot be performed.

In a conventional multi-tank or multi-tank vegetable washing apparatus, if the number of washing tanks is increased, the length of the main body becomes extremely long, so that a large installation space is required. Each time the food is transferred to the washing tank, it is necessary to scoop it upside down with a reversing transfer basket and throw it in again, or to scoop up the food on an oblique conveyor and drop it many times. Ingredients such as vegetables roll randomly by falling and throwing,
In addition, there is a problem that it is thrown into an adjacent tank, causing a problem such as pain or cracking, and cannot be used for fragile food such as tomato or peach or fragile food such as egg.

Further, in the multi-tank type vegetable washing apparatus, it is necessary to transfer foodstuffs to a series of adjacent washing tanks for washing (the use of a washing tank in the middle of a series of washing tanks is stopped). However, there is also a problem that it can only be used as a dedicated machine that performs almost the same series of cleaning steps.

Further, in a multi-tank or multi-tank vegetable washing apparatus, the starting position and the ending position of the washing step are specified at the end of the apparatus which is long in a straight line. There is also a problem that the transfer cooperation position to the next process is specified, and the design of the equipment arrangement in the catering system is restricted accordingly.
