Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a frozen dessert manufacturing machine that manufactures frozen desserts such as ice cream shakes and soft serve ice creams, and particularly relates to a frozen dessert manufacturing machine that is rotatably installed in a cooling cylinder. This invention relates to a stirring device.

(b) Conventional technology Publication of Utility Model Publication No. 59-8550 describes a front plate, a rear plate,
A stirring device is disclosed that includes a spiral dasher installed between a front plate and a rear plate, and a stirring rod and a blade eccentrically mounted between the front plate and the rear plate.

(c) Problems to be Solved by the Invention In such a prior art stirring device, the raw material mix supplied from the rear of the cylinder is smoothly pushed forward along the spiral dusher by the action of the helical dusher. This new mix was extracted with almost no mixing with the finished frozen desserts, which caused the problem that poor quality products were removed faster than the actual extraction capacity, especially when continuously removing frozen desserts.

(d) Means for Solving the Problems In order to solve the above-mentioned problems, the present invention includes a front plate, A stirring device is rotatably installed, which includes a rear plate, a blade, a spiral blade extending from the front plate to the rear plate, and an annular partition plate fixed to the spiral blade between the front plate and the rear plate in front of the inlet. be.

(e) Effect In the above configuration, when the frozen dessert finished in the cooling chamber is taken out to the outside by the extractor, new mix is replenished from the inlet into the cooling chamber to compensate for the shortage caused by this removal. Due to the action of the spiral blades, this mix is not immediately sent to the extractor in front, but is temporarily received by the partition plate and its flow direction is changed toward the center of the cooling chamber.
As a result, it is mixed well with the frozen dessert at the front of the cooling chamber, and the extraction of frozen desserts with extremely uneven temperature distribution is prevented.

(f) Example Fig. 1 is a perspective view of the stirring device of the present invention, and Fig. 2 is a sectional view of a cooling cylinder in which the stirring device of Fig. 1 is rotatably installed. It is equipped with a frozen dessert extractor 2 having an inlet 1A at the rear through which mixes, which are the so-called stock solutions of frozen desserts such as cream, flow, and an extraction passage 2A formed on the surface thereof, and furthermore, a freezing system evaporation pipe 3 is wound around the outer circumferential surface. It is a cooling cylinder with an adiabatic structure.

Next, the structure of the stirring device 4 disposed in the cooling chamber 1 for stirring and delivering the mix supplied to the cooling cylinder 1 will be explained. 5 is a front plate facing closely to the rear surface of the extractor 2; 6 is a cooling cylinder 1;
A rear plate 6 is located close to and opposite to the rear face, and a rotary shaft 7 passing through the rear face of the cooling cylinder 1 is connected to the plate 6 . 8 is a spiral blade arranged from the front plate 5 to the rear plate 6; 9 is located forward of the inlet 1A, and the peripheral edge is welded to the spiral blade 8 approximately in the middle of the front plate 5 and the rear plate 6. It is an annular partition plate,
Its outer diameter is slightly smaller than the inner diameter of the cooling cylinder 1. 10A is a swingable front blade with one end supported by the peripheral edge of the front plate 5 and the other end supported by the peripheral edge of the partition plate 9; 10B is 180° shifted from the front blade 10A; Rear blades 11A and 1 that are swingable with one end supported by the peripheral edge of the partition plate 9 and the other end supported by the peripheral edge of the rear plate 6;
1B is a reinforcing rod installed from the front plate to the middle partition plate 9 and then to the rear plate 6; 12 is a reinforcing rod extending inward from the cooling cylinder 1 from a support 13 screwed onto the extractor 2; Bearing 1 fixed at the center of rotation of face plate 6
The first fixing rod 12A inserted and supported by the first fixing rod 12A also extends from the support 13 in parallel with the first fixing rod 12A, and the rear end is bent near the rear plate 6 and welded to the first fixing rod 12A. The stirring fixing member 15 consisting of the eccentric second fixing rod 12B is a collar that is press-fitted into the outer surface of the support 13 and supports the front plate 5.

Next, the operation of the stirring device configured as above will be explained. First, mix is pumped from a mix supply source and is supplied in a fixed amount to the cooling cylinder 1 from the inlet 1A. Thereafter, when the cooling operation is started and the stirring device 4 is rotated, the mix is cooled and stirred, gradually increasing its viscosity and being finished into a frozen dessert. As the viscosity of the mix increases, the frozen dessert that tends to rotate together with the spiral blades 8 and blades 10A and 10B hits the first and second fixing rods 12A and 12B at fixed positions and is prevented from rotating together. It is sent forward by the spiral blade 8 while being efficiently stirred.

When the finished frozen dessert in the cooling cylinder 1 is extracted from the extractor 2, the missing amount is replenished as mix into the cooling cylinder 1 from the inlet 1A. Unlike the case described above, this mix is mixed into the frozen dessert, but while being sent forward by the spiral blade 8 that has a sending action, it hits the partition plate 9 and its moving direction is directed to the cooling cylinder 1. After being mixed well with the frozen dessert in the center, it moves forward. In this way, the mixing of the already existing frozen dessert and the newly supplied mix is ensured by the action of the partition plate 9, and the extremely uneven temperature distribution caused by the supply of the new mix is eliminated.

(G) Effects of the Invention As described above, the present invention has an annular partition plate in the stirring device, so that when the insufficient amount of extracted frozen dessert is replenished as mix into the cooling cylinder, this mix is already It is reliably mixed with existing frozen desserts, eliminates the extreme unevenness of temperature distribution caused by mix replenishment, and has the excellent advantage of being able to exhibit the ability to extract frozen desserts close to the cylinder volume even in continuous extraction of frozen desserts. .
