Abstract
A dip tank and recycling system for applying antimicrobial solution to food items, including a dip tank having a bottom and sides, and holding a liquid antimicrobial solution. A conveyor to convey food items through the tank passes through the liquid antimicrobial solution held in the tank such that food items conveyed on the conveyor are dipped in the liquid antimicrobial solution. At least two discharge nozzles spray fresh antimicrobial solution into the tank. The discharge nozzles are located in the sides of the tank, and are positioned above the level of the conveyor but below an expected top level of the liquid antimicrobial solution contained within the tank such that food items conveyed on the conveyor are agitated by the force of the spray from the discharge nozzles. The spray from the discharge nozzles causes unstacking of items on the conveyor, producing an even application of the antimicrobial solution.
