Furthermore, when the engagement between the engagement protrusion 21a and the engagement hole 29d and between the engagement protrusion 21b and the engagement groove 29f are released, the lid 29 is removed from the drive unit 5.

When the container body 27 is pushed downward after loosening the mounting screw 14, the engagement of the claw portion 11a with the engagement recess 3b is released due to the elastic deformation of the elastic piece 11b, as shown in FIG. After that, the support column 3c is inserted into the hollow part of the attachment part 27d. As a result, the mounting position of the container body 27 with respect to the support stand 3 is lowered so that the storage capacity of the frozen dessert manufacturing apparatus 1 is reduced.

In this way, in this embodiment, after the cylinder 33 is inserted through the packing 45 into the openings 35 and 41 of the locking piece 26a and the boss portion 28b which are overlapped with each other via the packing 43, the cylinder 33 is By screwing with a nut 47, it is possible to integrate the metal inner container 26 whose upper end is fixed with the synthetic resin outer container 28, thereby preventing leakage of the cool storage agent 32 sealed inside. be done.
Thereby, it is possible to efficiently cool the frozen dessert material and produce frozen desserts in a short time while preventing a decrease in cooling efficiency due to the cold storage agent 32.
