DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0002]

2. Description of the Related Art Conventionally, as an apparatus for producing ice cream for home use, an apparatus having the structure shown in FIG. 3 has been proposed.

[0003] This ice cream manufacturing apparatus comprises a material container 31 for accommodating an ice cream material 35 and a material container 3.
1, a cold insulator layer 33 stored between the material container 31 and the external container 32, and an external container 32.
And a heat insulating material layer surrounding the outer surface of the heat insulating material.

[0004] When the ice cream manufacturing apparatus of this configuration is employed, an ice cream can be manufactured in each household as follows.

First, only the cold insulator layer 33 is taken out, put in a freezer and sufficiently cooled, and then the sufficiently cooled cold insulator layer 33 is stored between the material container 31 and the outer container 32. The ice cream material can be manufactured by storing the ice cream material 35 in the 31 and stirring the ice cream material by the stirring device 36.

[0006]

The ice cream manufacturing apparatus having the above structure uses the cold insulator layer 33 for cooling the ice cream material. Therefore, the cold insulator layer 33 is considerably formed every time ice cream is manufactured. It has to be kept in a freezer for a long time, and there is a disadvantage that the time required for producing ice cream becomes longer as a whole.

When the shape of the cold insulator layer 33 changes,
Since it cannot be accommodated between the material container 31 and the external container 32, special consideration is required during the cooling period. In order to eliminate such consideration in cooling the cold insulator layer 33, the entire ice cream manufacturing apparatus or the cold insulator layer 33 and the material container 3 may be used.
1. It is conceivable that the external container 32 is housed in a freezer in an integrated state, but in this case, not only the occupied space becomes large but also the heat capacity becomes large, so that the cooling time becomes long.

[0008]
