Description

  The present invention relates to a food washing apparatus used for washing (including sterilization and rinsing) foods such as vegetables, seaweed, and seafood.

  Conventionally, as a food washing apparatus, a washing water tank for containing washing water is provided inside, and in the washing water tank, from a food input part on one end side provided with a running water inlet to a food take-out part on the other end side provided with a running water outlet. In addition to forming a transport cleaning path to the front, a take-out conveyor is attached to the food take-out section, an air ejection device is provided below the transport cleaning path, and the momentum of the cleaning water flowing in from the flowing water inlet and the air momentum from the air ejection device Is known to generate a water flow from the food input part to the food take-out part (see Patent Document 1).

  In this food cleaning device, the food to be cleaned that has been input to the food input unit is washed with the air bubbles from below, and the food cleaning unit is moved along the transport cleaning path by the water flow generated from the food input unit toward the food output unit. The to-be-cleaned food that has been sent to the side and conveyed to the food take-out section is taken out of the washing water tank by the take-out conveyor.

In such a food cleaning apparatus, foreign matters such as insects, hair, warax and food waste are generated during the cleaning, and removal of the foreign matters becomes an important problem.
Foreign substances having a specific gravity smaller than that of water float on the surface of the water, heavier ones float in the water, and those having a higher specific gravity settle on the bottom of the washing tank.

  Conventionally, as a device for removing foreign substances with low specific gravity floating on the water surface, a net conveyor for dust removal has been provided in front of the take-out conveyor, and the food to be cleaned is forcibly submerged in front of the take-out conveyor by the net conveyor for dust removal. It is known that foreign matter is discharged from an overflow hole (see Patent Document 1).

  However, this dust removal net conveyor can certainly remove foreign substances with low specific gravity floating on the water surface in the middle of the transport cleaning path, but the foreign matter removal efficiency is not 100%. Foreign matter that has passed through the conveyor is taken out from the takeout conveyor together with the food to be washed while adhering to the food to be washed, or stays on the water surface at the rear end of the washing water tank through the mesh of the takeout conveyor. End up.

In addition, as a device for removing foreign substances drifting in the water, a running water outlet is provided in the middle of the inclined rear wall of the washing water tank so that it opens to the middle of the water, and the water flowing out of this running water outlet is passed through the filtered water tank to the running water inlet. A washing water filtration / circulation device for returning is known (see Patent Document 2).
This washing water filtration / circulation device is intended to remove foreign substances drifting in the water, and for that purpose, the outlet of the running water is provided in the middle of the inclined rear wall so that it opens to the middle of the water. It was unsuitable for removing light foreign matter.
