Abstract: Automatic food frying and dispensing apparatus is disclosed which is housed in a supporting cabinet and includes a device for holding a supply of cooking oil and a heating device for maintaining the temperature of the cooking oil at a predetermined temperature. A fan assembly exhausts air through the top of the cabinet. A derated precipitator, a flame arrester and a charcoal filter are positioned upstream of the fan assembly and in the path of air flow. A switch device is positioned in the path of air flow and shuts off the heating device if the air flow drops below a predetermined value. Food handling apparatus automatically lowers the food to be cooked into the cooking oil when a customer selects a desired cooking time and automatically raises the food from the cooking oil and dumps the food into a container positioned at the food collection station at the end of the preselected cooking time.

Abstract: Food frying and dispensing apparatus is disclosed which is housed in a supporting cabinet and includes a device for holding a supply of cooking oil and a heating device for maintaining the temperature of the cooking oil sufficiently high for cooking successive batches of food products introduced into the oil by a food support basket. A fan assembly exhausts air through the top of the cabinet. A derated precipitator, a charcoal filter, a fragrance holding apparatus and an ozone generator are positioned upstream of the fan assembly and in the path of air flow to eliminate any smoke or odor produced within the apparatus prior to discharge of the air from the cabinet. Food handling apparatus pivotally positions the food support basket in three separate and distinct positions with the three positions being in the cooking oil in a "cook" position, out of the oil in a food product "dispense" position and out of the oil in a "ready" position.

Abstract: A portable electronic precipitator includes a two-stage type electrostatic percipitator mechanism mounted in a portable cabinet such as a wheel-mounted cabinet. The two stage type electrostatic percipitator is mounted in a vertical position with the inlet for the precipitator, containing the ionizer unit at the lower end of the precipitator with the collecting cell being mounted above the ionizer unit. A suitable fan is contained within the cabinet to pull air through the ionizer unit and then through the collector cell. The electrostatic precipitator mechanism is mounted above a particle fallout chamber. A freestanding arm, which is moveable in any desired direction is also mounted on the cabinet with a flexible hose surrounding and supported by the adjustable freestanding arm.
