ABSTRACT:
A coffee vendor comprising a brewer having a horizontal relatively small-mesh screen therein dividing the brewer into upper and lower chambers, a line for delivering hot water to the upper chamber of the brewer, a line for delivering filtered brewed coffee from the brewer, an air compressor for delivering compressed air to the upper chamber of the brewer, and a sanitizing system for cleaning the brewer and the delivery line. The sanitizing system includes a programmer motor for operation of the vendor through a sanitizing cycle comprising a series of successive hot-water rinse cycles. Switches operated by cams driven by the programmer motor program the sanitizing cycle, which is initiated by closure of a manual start switch, the cycle being automatically terminated. During each hot-water rinse cycle, hot water is delivered to the upper chamber of the brewer and thence allowed to remain in the upper chamber for a time interval during which it seeps down through the screen into the lower chamber of the brewer and then into and through the delivery line. Compressed air is then delivered to the upper chamber of the brewer for a second time interval following the first time interval for forcing hot water remaining in the brewer out of the brewer through the delivery line.
