FROZEN DESSERT FEEDING DEVICE

PROBLEM TO BE SOLVED: To provide a frozen dessert feeding device preventing a piston position thereof from moving at the time of exchanging frozen dessert or in waiting extraction of frozen dessert. SOLUTION: This frozen dessert feeding device drives a pressure pump 11 to bring a piston 16 back to the lowest point through detecting the operation condition of at least one selected from a cylinder bottom float switch 23 detecting the lowest point of the piston and a tank upper float switch 25 after the piston 16 falls down to the lowest point. It is all right to set parallel solenoid valves opening and closing passages or non-return valves circulating in a direction opposite to each other between a brine tank 12 and an extraction cylinder 14 so as to block the circulation of brine 13 between the brine tank 12 and the extraction cylinder 14 while the pressure pump 11 stops.
