PROBLEM TO BE SOLVED: To provide an ice cream maker where a mix is charged directly to a chilling cylinder from a material bag without depending on gravity and transferring the mix to a hopper to make ice cream. SOLUTION: The ice cream maker comprises the followings: a cold insulation storage 2 refrigerating a mix material bag 5 comprising a flexible bag body 21 where the mix is stored, and a flexible outer layer body 23 provided at the outside of the bag body so as to form a sealed space between the bag body and the layer body; a chilling cylinder 8; an air pump 27; a mix material tube 34 for making the inside of the mix material bag and the inside of the chilling cylinder communicate; a bag pressure pipe 7 for supplying the pressurized air to the space between the outer layer body and the bag body respectively of the mix material bag; an air circuit 51 for supplying the pressurized air to the inside of the chilling cylinder; and a sensor 47 provided in the air circuit. The mix material tube and the air circuit are joined together to maintain the pressure between the outer layer body and the bag body. COPYRIGHT: (C)2004,JPO
