ABSTRACT:
A self-contained and integrated multi-process power spray washer apparatus to be used to clean articles placed therein, the washer apparatus including a central washing chamber which is large enough to enclose and rotate an article to be cleaned therein. A primary filter removes contaminants from a cleaning solution immediately after it has been used, and a solution reservoir receives and holds filtered cleaning solution from the primary filter. A fan forced electronic burner heats the cleaning solution contained in the reservoir, and provides a heat source for contaminant incineration. An oil skimmer removes oil and grease from an upper surface of the cleansing solution held in the reservoir, and a secondary centrifugal filter through which cleansing solution is pumped from the reservoir additionally filters the solution. A high power sprayer sprays the recycled and clean cleansing solution into the washing chamber at a substantially high volume and pressure so as to substantially clean the item contained within the washing chamber. A fresh water rinse cycle provides for a final fresh water rinse of the article being cleaned and the recycling of the contaminated water prior to reuse or proper drainage. Accordingly, three steps of a cleaning process associated with the present invention include spray washing, recycling and disposal which are fully integrated in the self contained power spray washer apparatus.
