ABSTRACT:
A method and apparatus for cleaning articles such as pallets, totes, containers, bins, trays, carts, and other like articles. The apparatus includes a main housing having a conveyor system on which articles are transported into and through a washing chamber. The apparatus is versatile and employs adjustable guide rails to hold in place a wide variety of different sizes and configurations of a wide assortment of articles. A plurality of high pressure, jet-stream spray nozzles rotating at high speeds are supplied with a high pressure wash fluid. The spray nozzles provide rapid, powerful, knife-like jet streams of wash fluid which impact the surfaces of the articles moving through the washing chamber repeatedly to lift and blast off contaminants adhered to the articles. The apparatus is portable and includes a closed-loop water reclamation system having a plurality filter assembly and is environmentally friendly. Contaminant-entrained wash fluid is collected in a collection tank, filtered and supplied back to a clean tank for reuse. The apparatus does not require heated water nor a constant supply of fresh water for operation and has an extremely high throughput capacity to clean large quantities of articles quickly and consistently in a limited time. Optionally, but preferably, a pair of blower assemblies are provided for delivering columns of air which remove liquid on the articles as the articles leave the washing chamber and pass through the drying chamber. In an alternative preferred embodiment the apparatus includes two pairs of air knives which deliver extremely powerful columns of air to dry articles passing through the apparatus.
