Abstract
A system for dispensing flowable foodstuffs such as chili and the like. The system comprises a food-containing reservoir which is at least partially surrounded by a container filled with warm water or the like in order that the foodstuffs be kept in a warm and servable condition. The food reservoir is fitted with a valve generally of the plug or portion control type so that individual servings may be drawn from the reservoir. The dispenser is also fitted with a vacuum source such that a vacuum may be drawn at the upper levels of the food reservoir. An air inlet is provided into the reservoir preferably through the valve itself so that as the vacuum is being drawn on the reservoir, the valve simultaneously will be cleaned by the air flowing through it even when the valve is in its closed position. This air flow, in turn, agitates the flowable or chunky material so that it remains relatively homogenous and so that the chunky or suspended particles in the foodstuff do not settle to the bottom of the reservoir.
