Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates in particular to a stirring blade for an apparatus for producing frozen desserts such as ice cream.

2. Description of the Related Art As shown in FIG. 2, a conventional frozen dessert manufacturing apparatus of this type has a concave receiver formed on the upper surface of a main body case 1, and a cooling heat exchanger 4 is provided in an opening 3 of a seat 2. A container 5 with an open top is detachably provided in the cooling heat exchanger 4. Furthermore, the concave receiver seat 2 has teeth on the outer periphery, a blade insertion hole 6 in the center, and a guide hole 8 provided with an arm 7 connecting the blade insertion hole 6 and the outer periphery. A stirring gear 9 and a driving gear 10 are provided in mesh with the stirring gear 9. Furthermore, a motor 11 is connected to the drive gear 10. Further, inside the container 5, there is a blade shaft 12 located vertically at the center and a blade plate 13 extending in the circumferential direction from the blade shaft 12. A stirring blade 14 to be inserted and connected to 6 was housed.

Then, the material in the container 5 is cooled by the cooling heat exchanger 4, and the motor 11 is driven to rotate the drive gear 10 and further rotate the stirring gear 9. Since the stirring blade 14 is inserted and connected to the stirring gear 9, it rotates in the same manner. There, the ingredients are melted and cooled to make ice cream.

Problems to be Solved by the Invention However, in the above-described configuration, in order to observe the finished state of the ice cream during production, the observation must be made through the guide hole 8 of the stirring gear 9. However, the rotation of the arm 7 becomes an obstacle, making it difficult to observe. Furthermore, depending on the type of ice cream, it may be necessary to add confectionery or the like midway through the ice cream after it has been frozen to a certain extent, but in this case as well, it is difficult to add confectionery etc. due to the area of the guide hole 8 being limited. moreover,
When the ice cream is completed and the ice cream is to be taken out from the container 5, the stirring gear 9 is removed and the stirring blade 14 is left in the container 5 when taken out.
The vane shaft 12 was located in the center and was in the way. Furthermore, during stirring, due to the shape of the stirring blades 14, a large rotational moment is applied to the joint between the blade plate 13 and the blade shaft 12, so it is necessary to provide sufficient reinforcement to prevent breakage. had.

The present invention solves these conventional problems, and aims to provide a stirring blade shape that facilitates loading of ingredients, observation and removal of ice cream, and sufficiently withstands rotational moment during stirring.

Means for Solving the Problems In order to solve the above problems, the frozen dessert manufacturing apparatus of the present invention includes:
A stirring gear with a circular hole in the center and a plurality of blade connecting parts in the remaining annular part, and a plurality of gear connecting parts that connect with the blade connecting parts, and a continuous container from the blade connecting part. A side wall blade is provided that descends to the bottom along the side wall of the side wall, and a bottom blade is provided from the outer periphery of the bottom toward the center, continuing from the side wall blade, and connected to the bottom blade that extends from the other side at the center. It is equipped with stirring blades.

Effect of the present invention Due to the above-described configuration, the stirring gear has only a hole in the center, and the stirring blades do not have blade shafts in the center, so there is no obstacle to loading, observing, and taking out materials. It can be done smoothly. Furthermore, since the blades are connected to each other, there is no rotational moment concentrated on the blade shaft, and it can withstand sufficient strength.
Breakage can also be prevented.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

Note that the same members as in FIG. 2 are given the same numbers.

In Fig. 1, 9' is a stirring gear, which has a circular guide hole 8" in the center and an annular outer circumference. 15 is a blade connecting part, which is provided in plural numbers. .14゛ A side wall blade 17 is provided with a gear connecting part 16 that connects with the blade connecting part 15, and is connected to the gear connecting part 16 and descends along the side wall of the container 5 to the bottom surface. A bottom blade 18 is provided which continues from the side wall blade 17 and extends from the outer periphery of the bottom surface toward the center, and the bottom blades 18 extending from the other side are connected to each other at the center.

In the above configuration, since the gear connecting portion 16 of the stirring blade 14' and the blade connecting portion 15 of the stirring gear 9'' are engaged with each other, when the motor 11 is driven,
The agitator gear 9'' rotates via the drive gear 10, and the stirring blade 14' also rotates. Also, since the container 5 is cooled by the cooling heat exchanger 4, ice cream can be made by stirring while cooling. .Also, the stirring gear 9
゛ has an annular shape with an 8° circular guide hole in the center.
The Gakuhan blade 14" does not have the conventional blade shaft 12 in the center, so it is easy to add ingredients, observe and take out the ice cream. Also, the moment applied to the blade is not concentrated on the shaft. There is an effect.

Effects of the Invention As described above, the frozen dessert manufacturing apparatus of the present invention has a stirring gear provided with a guide hole in the center portion and a plurality of blade connecting portions in the remaining annular portion, and a blade connecting portion of the stirring gear. A gear connecting part is provided that meshes with the outer part of the container, and the blades are connected from this part and descend along the side wall of the container to form the side wall blades. By providing a stirring blade which is connected to the bottom blade coming from the other side at the center,
When the motor is driven, the stirring gear rotates via the driving gear, and the stirring blades also rotate. Once the container is cooled, ice cream is created by stirring while cooling.

Additionally, there is only a guide hole in the center of the stirring gear, and there is no blade shaft in the center of the stirring blades, so when observing the finished state of the ice cream, there are no obstacles and the inside can be clearly observed.

Also, depending on the type of ice cream, fruits or the like may be added during the process, but this can also be done easily without any obstacles. Furthermore, the ice cream can be easily removed from the container after it is completed, with the stirring blade remaining in the container, since it does not become an obstacle. Even during agitation, the moment applied to the blades is received by the blades, thereby increasing the bonding strength between the blade shaft and the blade plate and preventing breakage, unlike in the conventional case.
