Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food washing apparatus for washing vegetables, marine products, seafood and the like, and a food washing and sterilizing apparatus for washing and sterilizing food at the same time.

[0002]

2. Description of the Related Art Conventionally, as a food cleaning device, for example,
There is a type in which an object to be cleaned is cleaned by air bubbles ejected from an air outlet of an air delivery pipe and the object to be cleaned is transferred from an inlet side to an outlet side by a flow of cleaning water generated by the air bubbles. Conventionally, food is washed and sterilized by first washing it with a washing device and then transferring it to the sterilizing device.

[0003]

However, since the former food cleaning apparatus cannot control the transfer speed of the object to be cleaned, it is possible to perform cleaning according to the type and purpose of the object to be cleaned. There was a problem that I could not.
Further, in the conventional food cleaning apparatus, the object to be cleaned stays in the cleaning tank and does not flow smoothly due to the generation of vortices and the like, so that there is a problem that many kinds of food cannot be continuously cleaned. In the latter cleaning and sterilizing method, first, the food is washed by the cleaning device and then transferred to the sterilizing device for sterilization, so it takes manpower to transfer the cleaned food to the sterilizing device. There was a problem that workability was poor.
Also, in the past, since the food stored in the basket was simply immersed in high temperature water in the sterilizer, uneven sterilization occurred between the surface and the center of the basket, and uniform sterilization was performed. There was a problem that it could not be done in a short time.
In order to uniformly sterilize the food in the basket, the worker manually stirs it, but in this case, there is a safety problem such as the worker being burned by hot water. The present invention is invented in view of the above-mentioned circumstances, and an object thereof is to efficiently perform cleaning according to the type of food, and to continuously produce many kinds of food with one machine. To provide a food cleaning device capable of performing uniform cleaning, and to perform uniform sterilization and cleaning of food in a short time and sterilization and cleaning of various kinds of food continuously. To provide a device.
