DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food washing apparatus used for sterilizing, desalting, and washing foods such as vegetables, seaweeds and seafood.

[0002]

2. Description of the Related Art Conventionally, as a food cleaning apparatus, a cleaning tank for containing cleaning water is provided therein, and a transport cleaning path from a food input section on one end to a food removal section on the other end is provided in the cleaning tank. At the same time, a transport air ejection device that attaches a take-out conveyor to the food take-out section and that blows air from the food input section toward the food take-out section in the transport wash path below the transport washing path is provided. It is provided.

Therefore, in this food cleaning device, a water flow is generated from the food input section toward the food extraction section in the transport cleaning path by the force of the air ejected from the conveying air jetting apparatus. Is washed by blowing air bubbles from below, and while moving up and down repeatedly, the water is sent to the food take-out section by the water flow, and the food conveyed to the food take-out section is washed by the take-out conveyor. Is taken off the outside of the

[0004]

However, in the conventional food cleaning apparatus, since the force of the air ejected from the conveying air jetting apparatus is constant, the conveying cleaning path is lengthened in order to enhance the cleaning effect. Therefore, there is a problem that the device becomes large and the installation space becomes large.

[0005] When the force of air is strongly adjusted by an air adjusting valve, the cleaning power by air bubbles is improved, but the cleaning time is shortened because the transport speed by water flow is increased.
The cleaning effect as a whole cannot be improved. Conversely, if the force of the air is weakly adjusted by the air adjustment valve, the cleaning time becomes longer because the transport speed by the water flow becomes slower, but the cleaning power due to the bubbles is reduced, so that the overall cleaning effect cannot be improved. .

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and it is an object of the present invention to improve the overall cleaning effect by increasing the transport time while maintaining the cleaning power by air bubbles. It is therefore an object of the present invention to provide a food cleaning apparatus which can reduce the size of the apparatus.

In order to solve the above-mentioned problems, a food washing apparatus according to the present invention (Claim 1) is provided with a washing tank containing washing water therein, and this washing tank has A transport cleaning path is formed from a food loading section on one end side to a food removal section on the other end, and a take-out conveyor is attached to the food removal section. In a food washing apparatus provided with a conveying air jetting device for jetting air so as to generate a water flow toward a food take-out portion from the food washing device, braking is applied to the water flow in the conveying washing route in the middle of the conveying washing route. A configuration is provided in which a braking air ejection device for ejecting air is provided.

In the food washing apparatus of the present invention, a water flow is generated from the food input section toward the food take-out section in the transport washing path by the force of the air ejected from the transport air ejection apparatus.
The food introduced into the food introduction section is washed by blowing air bubbles from below, and is repeatedly sent up and down to be sent to the food takeout section by the water flow by the water flow. Further, since a braking air ejection device is provided in the middle of the transport cleaning path, braking (brake) is applied to the water flow in the transport cleaning path by air ejected from the braking air ejection device. The transport speed of the food is reduced by the braking. As described above, when the transport speed of the food decreases in the middle of the transport cleaning path, the subsequent foods start to be congested one after another, so that the cleaning time can be increased.
