Description

  INDUSTRIAL APPLICABILITY The present invention is used in an operator's hand washing process in final washing or the like performed before packaging and shipment of food such as vegetables and fruits, or in other electronic, mechanical parts, industrial parts, industrial equipment washing processes, etc. It relates to a washing machine by hand washing.

  Vegetables, fruits and other foods are taken directly into the human body, and therefore strict food hygiene management is required, and various devices have been proposed for cleaning them. Yes. As a general vegetable cleaning device, a conveyor for transportation is placed in the water tank, and a cleaning mechanism such as a wiping cloth, a plate brush, or a rotating brush is installed above the transport surface of the conveyor. There are some that remove dirt and deposits attached to the surface.

Conventional devices are designed to remove foreign substances attached to the surface of the object to be cleaned by rising air by placing a dedicated conveyor line in the water in order to process a large amount of vegetables, etc., aerating from the bottom of the tank. Most of them are large and expensive, and are used for primary cleaning in a state where soil or wrapping paper after harvesting is attached to the surface. On the other hand, for example, in Japanese Patent Application Laid-Open No. 2003-9834, the applicant has proposed an apparatus that can reliably remove hair or foreign matters by paying attention to the arrangement and driving direction of the conveyor.

However, in this device, in the case of so-called roots such as radish, eggplant, cucumber and block-like items of a certain size, continuous washing is possible by conveyor transport, but leaves such as Nozawana, Takana and Chinese cabbage There is a possibility that effective cleaning cannot be expected even if this apparatus is used. Moreover, the apparatus of this patent document is equipped with a conveyor and is expensive to some extent. In addition, leafy vegetables, etc., sometimes have sand or soil bitten between the leaves, and when they are packaged and shipped, they are discovered during the consumption process and all lots are returned. The impact on corporate life can be seen in recent examples. Further, when human hair or the like is pinched and attached, it is extremely difficult to remove the hair, and in a large-scale treatment apparatus, there is a possibility that the attached hair is once separated and the floating hair or the like is attached again. Furthermore, there is an apparatus for effectively washing leaves and the like in fruit vegetables, which has never been low-cost equipment that can be easily obtained by a small-scale producer or processor. The emergence of such a device was awaited.

The present invention has been made in view of the above-described conventional problems, and one object of the present invention is to reliably clean fruit vegetables such as leaves, which have been difficult in the past, while being low in cost. It is an object of the present invention to provide a hand-washing machine for fruit and vegetable foods that can reliably remove foreign substances in the final cleaning in the cleaning process immediately before packaging.
