Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a stirring machine for ice cream, etc., which stirs ice cream and other confectionery materials such as tiocolate and kutsky, or fruits such as bananas and strawberries. It can be used as a stirrer for mixing, and also as a stirrer for other dairy products, paste products, etc.

2. Description of the Related Art An extrusion spiral is rotated within an extrusion cylinder, and the material is transferred from a supply hopper side toward an extrusion hole at the tip of the extrusion cylinder, agitated, and extruded from the extrusion hole.

Problems to be Solved by the Invention In a stirring mode where a small amount of ingredients are stirred for each serving such as ice cream and taken out into a small-capacity ice cream cup or middle cup, an extrusion spiral is incorporated. Increasing the capacity of the extrusion tube increases the amount of material remaining, which is uneconomical as excess material must be supplied.

Means for Solving the Problems This invention provides a cup 3 having an extrusion hole 1 at the bottom and receiving material such as ice cream, which is rotated in the opposite direction and then rotated in the forward direction while being fitted relative to the cup 3. The stirrer for ice cream or the like is provided with an extrusion spiral 5 for stirring the material in the cup 3 and extruding it from the extrusion hole 1.

Effect of the Invention When the extrusion spiral 5 and the cup 3 are in a vertically spaced apart position, for example, an ingredient such as ice cream or fruit is supplied to the lower cup 3, and while the extrusion spiral 5 is rotated and transmitted, When the cup 3 is inserted into the cup 3 from the spaced apart position, the ice cream and the fruit mixture in the cup 3 are stirred, and the fruit-mixed ice cream is inserted into the cup 3.
It is extruded from the extrusion hole 1 at the bottom. The lower side of the extrusion hole 1 receives a predetermined amount with an ice cone cup or the like.

During the initial stroke when this extrusion spiral 5 is inserted into the cup 3, this extrusion spiral 5 is reversely rotated to stir the material upwardly, and when it is further inserted into the cup 3, this extrusion spiral 5 is switched to normal rotation, and the material in the cup 3 is further stirred and extruded toward the extrusion hole 1. When the ice cream in the cup 3 runs out, the extrusion spiral 5 and the cup are separated.

Effect of the invention The extruded spiral 5 that fits into the cup 3 in this way
However, at the beginning of this insertion, the material is stirred by rotating in the opposite direction, so the material is once raised inside the cup 3 so that no extrusion pressure is applied to the extrusion hole 1, so that the material is not stirred. The ice cream is prevented from being extruded as it is, and the ice cream is rotated in the forward direction as it is inserted deeper than in the reverse direction, thereby increasing the stirring effect and extruding the ice cream from the extrusion hole 1 after stirring.

Embodiment In FIGS. 1 to 6, the cylindrical body 2 is provided with an opening 7 on the lower front surface through which a cup 3, etc. can be taken in and out, and a cleaning hole 8 is provided in the center of the bottom of the body 2.

In FIG. 7, a notch 37 is provided in the extrusion spiral 5 to enhance the stirring effect; one thread forms a continuous spiral edge 35, and the other thread forms an intermittent spiral edge 36 with a cutout 37. At the same time as the intermittent spiral edge 36 has a stirring effect, the continuous spiral edge 35 can extrude and guide the ice cream that escapes upward through the notch 37 so that the extrusion function does not deteriorate.

FIG. 8 shows an intermittent screw rim 36 with a notch 37.
is provided in two strips, and the phases of the notches 37 between these two strips are shifted so that the notches 37 are not continuous at the same axial position, and the purpose is the same as that in the case of Fig. 7. This is to achieve the following.

These various types of extrusion spirals 5 can be attached to and detached from the lower end of the shaft 4 using mounting bolts 38.

FIG. 9 shows the contacts of the motor 13 that are turned on and off by turning the handle 24. A cam 40 is provided on the shaft 39 of the handle 24 so as to rotate together with the cam 40. Contact points 41 and 42 of a motor 13 consisting of a micro switch are arranged in the rotation area, and when the contact point 41 is turned on by a cam 40, the motor 13 is reversed and the extrusion spiral 5 is directed in the direction of extruding the material downward. is rotated in the opposite direction, contact 4
2 is turned on, the motor 13 switches to normal rotation, and the extrusion spiral 5 is rotated in the direction of extruding the material downward. These forward and reverse switching rotations of the extrusion spiral 5 are related to the operating angle of the handle 24, and in the initial stroke (FIG. 5) when the extrusion spiral 5 is inserted into the cup 3, the cam 40 enters the contact point 41. In the process of reverse rotation and lowering and fitting (FIG. 6), the contact 42 is brought into contact to transmit forward rotation. Further, when the extrusion spiral 5 descends and rises with the return of the handle 24, the contact 41 is momentarily turned on and the motor 13 does not rotate in the reverse direction. or,
When this extrusion spiral 5 rises, the contact point 41 or 4
It may be configured to cut 2.

In the position where the handle 24 is rotated to the upper end as shown in FIG. 1, the extrusion spiral 5 escapes upward from the cup 3 and is housed in the lower end of the guide tube 6. In this state, from the opening 7 into the cup 3,
Materials such as ice cream and fruit are supplied in predetermined amounts, and the handle 24 is rotated downward.

When the extrusion helix 5 is inserted into the cup 3, during this initial stroke the contact 41 is turned on and the motor 1 is turned on.
3 is reversely rotated and rotated in the opposite direction via the belt 15, inner shaft 16, outer shaft 17, etc. (Figs.
Figure 5). The material in the cup 3 is scraped upward by the reverse rotation of the extrusion spiral 5, starting a stirring action.

When the extrusion spiral 5 is further lowered by operating the handle 24, the contact 42 is turned on and the direction of rotation by the motor 13 is switched to the normal rotation direction, working in the direction of extruding the material in the cup 3 downward. At this time, the stirring effect of material A is good. In this way, when the extrusion spiral 5 is lowered by forward rotation, the extrusion spiral 5 extrudes the ice cream from the extrusion hole 1.
If a cup such as an ice cream cone is held under the extrusion hole 1 by hand, the ice cream can be filled into the ice cream cone.

When the material A in the cup 3 is extruded, the extrusion spiral 5 is raised by rotating the handle 24 upward, and the guide tube 6 above the cup 3 is raised.
inserted inside. Further, the transmission of this extrusion spiral 5 is also stopped.

When using the extrusion spiral 5 having a notch 37 as shown in FIG. 7 or 8, the stirring effect is enhanced, but the material that escapes upward through this notch 37 is located above this notch 37. The material is extruded downward by the helical edge, and therefore does not significantly reduce the extrusion rate during material extrusion.
