Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a frozen dessert making machine that manufactures frozen desserts by cooling and stirring raw material mixes such as soft serve ice cream in a cooling cylinder. This relates to an installed stirring device.

(b) Prior art Japanese Utility Model Publication No. 58-20143 discloses a stirring device that stirs raw material mix for soft serve ice cream, etc. using a spiral dossier and a stirring rod that are rotatably installed in the cylinder of the main body of a frozen dessert making machine. is disclosed. The blade of such a stirring device is fitted so as to be able to swing between a convex portion protruding from one end of the front plate and a locking groove formed at one end of the rear plate.

(c) Problems to be solved by the invention By the way, the cutting edge of the blade of the stirring device wears out because it scrapes off ice crystals frozen on the inner wall of the cooling cylinder. Blade wear reduces cooling capacity,
Since it causes a deterioration in the quality of frozen desserts, it is necessary to replace it periodically.

In the conventional blade, the entire blade was made of a single component, so even if the cutting edge wore out, the entire blade had to be replaced, making it very expensive.

Therefore, in view of the problems of the prior art, the present invention provides an inexpensive blade in which the blade is composed of two parts and only the cutting edge portion can be replaced.

(d) Means for solving the problems In order to solve the problems of the above-mentioned conventional technology, the present invention provides a rigid structure with a frozen dessert dispenser on the front and an inlet for raw material mixes such as soft serve ice cream on the rear. A frozen dessert manufacturing machine in which a stirring device consisting of a cooling cylinder for raw material, a front plate, a rear plate, a spiral blade and a blade extending from the front plate to the rear plate is rotatably installed in the cylinder, the blade has an end portion a holding part made of a rigid material that is detachably supported on the front plate and the rear plate, respectively; and a cutting edge part made of resin that is detachably fitted into the holding part; Both ends are provided with abutting portions for regulating the axial position of the cutting edge.

(E) Effect The present invention consists of the blade 10 consisting of two parts, the holding part 11 and the cutting edge part 12, and the convex part 11C of the holding part 11.
By inserting and fitting the recessed groove 12B formed in the axial direction of the cutting edge part 12 into the blade edge part 12, only the cutting edge part 12 can be replaced.

(f) Examples Examples of the present invention will be described below based on the drawings. 1 has an inlet 1A at the rear through which mixes, which are undiluted solutions for frozen desserts such as soft serve ice cream and ice cream shakes, flow in, and a frozen dessert dispenser 2 at the front.
A cooling cylinder made of a rigid material made of stainless steel and further having a frozen dessert evaporation pipe 3 wound around its outer circumferential surface,
Reference numeral 4 indicates a mix tank for storing raw material mix supplied to the cooling cylinder 1 via a mix supply pipe 5 inserted into the inlet 1A; 6 indicates the cooling cylinder 1;
The stirring device of the present invention is rotatably installed inside a front plate 7, a rear plate 8, a spiral blade 9 extending from the front plate 7 to the rear plate 8, and a blade 10 composed of two parts that can be disassembled. It is mainly composed of

To be more specific, the blade 10 has shaft parts 11A provided at both ends that are removably supported by the front plate 7 and the rear plate 8, respectively, and are rotatable holding parts made of a rigid stainless steel material. 11 and a cutting edge portion 12 made of resin such as Diuracon. Furthermore, the holding part 11 is attached to the shaft part 1.
1A is inserted between the bases 11B at both ends.
A right-angled stepped portion 1 for positioning and position regulation is formed at the intersection of the convex portion 11C and the base portion 11B.
It forms 1D. On the other hand, the cutting edge portion 12 has a cutting edge 12A formed on one side in the axial direction, a groove 12B that fits into the insertion convex portion 11C on the other side in the axial direction, and abuts the right angle step portion 11D at both ends. A right-angled abutment portion 12C that is in contact with or in close proximity to the abutment portion 12C is formed.

Therefore, by inserting and fitting the concave groove 12B into the convex part 11C and aligning the abutting part 12C with the right-angled step part 11D, the attachment of the cutting edge part 12 to the holding part 11 is completed, and moreover, during stirring, The cutting edge portion 12 can stably scrape off frozen desserts from the inner wall of the cooling cylinder 1 without being displaced in the axial and radial directions.

In addition, the blade 10 due to wear of the cutting edge 12A, etc.
When replacing the blade, the blade edge part 12 can be removed from the holding part 11 and only the blade edge part 12 can be replaced.

(g) Effects of the invention As described above, the present invention consists of a blade consisting of two parts, a holder and a cutting edge part, and the cutting edge part is removably fitted into the holding part, thereby eliminating the need for blade replacement due to wear of the cutting edge. This can be done by removing only the cutting edge from the holding part, which has the practical advantage of reducing the cost of replacing the blade, and also allows the holding part to be made of the same material as the cooling cylinder or a material stronger than the cylinder. This has the added advantage of increasing the strength of the blade. Furthermore, by forming the cutting edge part with resin and providing abutting parts for regulating the position of the cutting edge part in the axial direction at both ends of the cutting edge part, the cutting edge part is made of resin, so that the cooling cylinder surface can be No more damage is caused, this cylinder surface is maintained smoothly, and the position of the cutting edge is regulated in the axial direction with respect to this smooth cylinder surface, so that it can stably contact without positional deviation. The ability of the blade to scrape off frozen confectionery from the cylinder surface can be maintained well.
