Description

[Detailed Description of the Invention] The present invention relates to a cotton candy manufacturing apparatus that manufactures cotton candy using a cotton candy discharge rotating body that rotates heated and melted raw materials in the form of fibers and discharges them.

Conventionally, the cotton candy dispensing rotating body of cotton candy manufacturing equipment was heated by gas, so the gas was combusted and decomposed into carbon dioxide and water, and the water adhered to the cotton candy, causing its fibrous It was difficult to maintain the shape for a long period of time.

In addition, there is also a device in which a large number of circular or slit-shaped through holes are bored in the peripheral side wall of the cotton candy dispensing rotary body, and a nichrome wire heater is attached to the inner periphery of the peripheral side wall. In order to prevent electrical leakage or short circuits from occurring, the parts surrounding the nichrome wire heater are treated with a hollow finish or the like to form heat-resistant insulating parts. However, it is difficult to completely finish the hollow finish, which is an insulating part, and it is extremely dangerous as some parts are not insulated, and there are pinholes, etc., which can easily become dangerous after long-term use. Hollow finishing itself is also not suitable for mass production. In addition, in order to supply power to the nichrome wire heater in the rotating cotton candy dispensing body, it is necessary to add a slip ring that can withstand high pressure, a rotary transducer, etc. to the rotating shaft of the cotton candy dispensing body, which increases the size of the equipment itself. .

There is also a device (Utility Model Publication No. 44-30718) in which the cotton candy dispensing rotor is heated by radiant heat from a fixed nichrome wire heater, but this type of device heats the cotton candy dispensing rotor to the desired temperature. It takes time to heat up to 100%, and the heating temperature fluctuates as the heat load changes depending on the amount of raw materials supplied.

Furthermore, if the cotton candy raw material used is only a single sugar, these conventional devices can produce continuous cotton candy fibers by predetermining the number and diameter of the molten raw material discharge holes. can. However, even in this case, cotton candy fibers are produced by rotating the cotton candy dispensing rotary body at high speed, but if the rotation speed is too fast or too slow, good cotton candy fibers cannot be obtained, and the rotation The number is difficult to determine. Further, there is a problem in that it is difficult to adapt the method to the use of raw materials mixed with disaccharides or mixtures thereof or other chewing gum bases.

The present invention was developed in view of the above-mentioned problems, and its purpose is to solve the hygroscopic phenomenon caused by the moisture produced by the decomposition of combustion gas on cotton candy, and the electric heating of the cotton candy dispensing rotating body. To provide a cotton candy manufacturing device which solves problems such as electric leakage and slow temperature rise, and which can easily produce good cotton candy even when the cotton candy contains a single substance or a mixture of disaccharides, etc., and other raw materials such as chewing gum base. There is a particular thing.

Therefore, the configuration of the present invention to achieve this purpose is to provide a cotton candy material having a material melting chamber into which raw materials for cotton candy such as sugars can be freely input and in which a through hole for discharging the melted material is formed in the peripheral wall. In a cotton candy manufacturing apparatus having a confectionery discharging rotary body and a heating means for heating the raw material melting chamber of the cotton candy dispensing rotary body, the cotton candy dispensing rotary body is formed of a magnetic material, and one end thereof is made of a magnetic material. A jacket having a cylindrical part extending concentrically with the center line of rotation of the cotton candy dispensing rotating body, extending from the cylindrical part to the raw material melting chamber over the entire circumferential direction, and enclosing a heat medium therein. A fixed cylindrical body is provided inside the cylindrical part and is arranged concentrically with the cylindrical part, a notch is formed at a part of the circumferential direction of the fixed cylindrical body and is continuous in the axial direction, an excitation coil supported by the cotton candy dispensing rotor and facing the inner surface of the cylindrical portion of the cotton candy dispensing rotor, and by supplying an alternating current power to the excitation coil, the cotton candy dispensing rotor is heated and the cotton candy dispensing rotor is heated. One or more layers of mesh are replaceable and movable with respect to the cotton candy discharging rotary body at positions outside and/or inside of the molten raw material discharge holes on the outer circumference and/or inner circumference of the confectionery discharging rotary body. This is due to the fact that it was installed in

Next, an example of implementation of the present invention will be described with reference to the drawings.

FIGS. 1 and 2 show a cotton candy discharge rotating body for melting the cotton candy raw material used in the present invention and discharging it in the form of fibers.

The cotton candy dispensing rotating body 1 is formed in a cylindrical shape, and a rotating shaft 2 is inserted into the center thereof, and is fixed to the rotating shaft 2 by tightening a nut 3.

On the other hand, a raw material melting chamber 4 is provided at one end of the cotton candy discharge rotating body 1. This raw material melting chamber 4 has an opening 4a on the end face of the cotton candy discharging rotary body 1 whose diameter is smaller than that inside, and a large number of through holes 5 for discharging the molten raw material made of small diameter holes in the peripheral wall. is formed,
A fine wire mesh 6 is stretched over the outer surface of the portion where the through hole 5 for discharging the molten raw material is formed. It is also possible to extend it on the inner surface if necessary.

The mesh of the wire mesh 6 and the number of stacked sheets can be changed depending on the cotton candy raw material used, thereby allowing the through holes 5 to be substantially changed.

Further, on the other end side of the cotton candy dispensing rotary body 1, a cylindrical portion 7 is integrally extended in the form of a skirt and arranged concentrically with the rotation center of the cotton candy dispensing rotary body 1. The cotton candy dispensing rotary body 1, including the cylindrical portion 7, is entirely made of a magnetic material. This magnetic material includes, for example, silicon steel and iron materials, such as carbon steel for machine structures and rolled steel for general structures as defined in the Japanese Industrial Standards.

A fixed cylindrical body 8 is inserted inside the cylindrical part 7 in a concentric arrangement therewith. The fixed cylindrical body 8 is made of the same magnetic material as the cotton candy dispensing rotor 1 described above, and an excitation coil 9 is wound around its outer circumferential surface. It faces the inner surface of the cylindrical portion 7 of No. 1 with a slight distance therebetween.

An AC power source is connected to the excitation coil 9, and the broken line A in FIG.
As shown, a closed magnetic circuit is formed between the cylindrical portion 7 and the fixed cylindrical body 8, and an alternating magnetic flux is generated in the circuit. At the same time, a short circuit current flows through the cylindrical portion 7 as shown by the broken line B in FIG. 2 due to the electromagnetic induction effect of the coil. The cotton candy dispensing rotating body 1 is heated by the heat generated by the hysteresis loss of the cotton candy dispensing rotating body 1 itself due to the passage of this alternating magnetic flux and by Joule heat due to the short circuit current.

Note that 8a in the figure is a notch that is located at a part of the circumferential direction of the fixed cylindrical body 8 and is continuously formed along the axial direction. Even if the circumferential direction short-circuit current does not flow, generation of Joule heat is prevented, and the excitation coil 9 is reliably prevented from being damaged by heat.

10 in the figure is a jacket chamber that extends from the cylindrical portion 7 to the raw material melting chamber 4 and is disposed over the entire circumferential direction, and has a heating medium sealed inside.The heating medium sealed in this jacket chamber 10 has a heat of evaporation The larger the temperature distribution, the more effective it is to improve the overall temperature distribution of the cylindrical body 1, and the jacket chamber 10 is sealed while leaving an evaporation space for the heat medium. When the cotton candy dispensing rotary body 1 rotates while generating heat due to electromagnetic induction, water, which is a heat medium, is heated to a high temperature portion of the cotton candy dispensing rotary body 1, that is, the cylindrical portion 7 facing the excitation coil 9. The water evaporates and removes heat from that area, and the peripheral wall portion of the raw material melting chamber 4 having the through holes 5 for discharging the molten raw material gives heat by condensation. The temperature of the cotton candy dispensing rotor 1 is made uniform by the heat conduction effect of the magnetic material of the cotton candy dispensing rotor 1 and the heat flow through evaporation and condensation.

By heating the cotton candy discharging rotary body 1 in this way, the cotton candy raw material introduced into the raw material melting chamber 4 is melted, and the high speed rotation of the cotton candy discharging rotary body 1 causes the through holes 5 for discharging the molten raw material to melt. It is discharged in a more fibrous form.

Next, an example of a device using a cotton candy rotating body as described above will be explained with reference to FIGS. 3 and 4. This cotton candy discharging rotating body 1 is fixed to a horizontal rotating shaft 2. The bearings 14, 14 are mounted on the frame 13.

The head of the cotton candy discharge rotating body 1 supported in this way is inserted through the opening 12a of one side wall 11a of the cotton candy recovery chamber 11, and the opening of the raw material melting chamber 4 at the tip is inserted into the opening 12b of the other side wall 11b. The through hole 5 portion for discharging the molten raw material is located within both side walls 11a and 11b. Then, the raw material input pipe 1 passes through the opening 12b.
The tip of 7 is inserted into the raw material melting chamber 4 of the cotton candy discharge rotating body 1. This raw material input pipe 17 is connected to the lower end of a raw material tank 19 supported on a pedestal 18, so that a fixed amount of cotton candy raw material is flowed down by a feeder 20.

A perforated net, a net made of threads coated with fluororesin and woven together, etc. can be used. The mesh can be appropriately selected as long as it has a size that prevents the cotton candy fibers discharged from the cotton candy discharge rotor from falling downward.

A gas suction chamber 22 is provided below the cotton candy collection chamber 11 and below the endless mesh belt conveyor 21.

On the other hand, the cotton candy dispensing rotating body 1 is rotated at high speed by a motor 16 and heated by applying AC power to the excitation coil 9.

The temperature of the cotton candy dispensing rotating body 1 is controlled by adjusting the electric power applied to the excitation coil 9 using a slider, a thyristor, a saturable reactor, etc.

In the case of cotton candy raw materials containing chewing gum base, the cotton candy discharge rotating body 1 is heated by induction heating.
Heat to around 150℃ to melt, sugar, glucose,
In the case of raw materials for cotton candy made of sugars such as maltose and lactose, either singly or as a mixture, the cotton candy discharge rotating body 1 is heated to about 180 to 200° C. by induction heating to melt the cotton candy.

The cotton candy raw material is subjected to centrifugal force while being induction heated in the cotton candy discharge rotating body 1, and is passed through the molten raw material discharge through hole 5.
It is expelled as a more continuous cotton candy fiber.

The wire mesh 6 on the outside of the through hole 5 for discharging molten raw material is a double layer of mesh of about 100 mesh (Japanese Industrial Standards) or punched metal of the same size in the case of raw materials for manufacturing cotton candy containing only sugars. By doing so, it is possible to produce continuous fibrous cotton candy P, and in the case of cotton candy raw materials containing chewing gum base, it is possible to produce 50 to 100 mesh (Japanese Industrial Standards).

The strip-shaped cotton candy P that has been lightly pressed by the pressing roller 24 is evenly and lightly pressed by the two side rollers 26, 26 on the forming conveyor 25, and is further lightly pressed by the second pressing roller 27. The surface is made uniform by pressing, and cut and formed between the conveyors 25 and 28 by a cutter 29.

The cotton candy manufacturing apparatus of the present invention is constructed as described above, and since the cotton candy discharging rotor is made of magnetic material, the internal electrical resistance as an inductive load under room temperature or low temperature conditions is small, and AC power is applied to the excitation coil. In this case, at the initial stage of temperature rise, a commensurately large short-circuit current is induced, and the amount of heat generated transiently reaches a maximum, and as the temperature rises, the rated current gradually decreases due to the relationship with the resistance coefficient of the magnetic material of the cotton candy dispensing rotor. It decreases to

Therefore, the temperature rise time is short, and the temperature is 3/3 compared to a cotton candy dispensing rotor using a normal nichrome wire heater of the same capacity.
It will be shortened by about 4 to 2/3.

Further, as mentioned above, the cotton candy dispensing rotary body is provided with a jacket chamber which is heated by electromagnetic induction and is disposed over the entire circumferential direction from the cylindrical portion to the raw material melting chamber, and in which a heating medium is sealed. Therefore, the cotton candy dispensing rotary body directly becomes a heat generation source, so there is no need to select a material such as copper or aluminum with high thermal conductivity as in the conventional cotton candy dispensing rotary body, and any magnetic material may be used.

Furthermore, since the cotton candy dispensing rotating body does not have a heat source such as a nichrome wire heater, additional equipment such as a slip ring or rotating transducer to supply power to the rotating part is generally not required, and there is no need for electrical leakage or leakage.
There are extremely few sparks and other malfunctions, making it highly safe.

Furthermore, when the heat load fluctuates due to changes in the supply amount of cotton candy raw materials, the temperature of the heated cotton candy dispensing rotor decreases, the resistance coefficient of the magnetic material changes, and a large short-circuit current flows, causing an immediate rise in temperature. Start heating. Therefore, even if the supply amount of the cotton candy raw material changes, the thermal fluctuation of the cotton candy discharging rotor itself is small, thereby making it possible to produce cotton candy with uniform cotton candy fiber thickness and weight.

Furthermore, one or more meshes can be freely replaced on the outer and/or inner periphery of the rotating discharge body for forming cotton candy fibers, and on the outside and/or inside of the molten raw material discharge holes, and the mesh can be replaced. Therefore, by substantially changing the pore size and number of the pores, it is possible to produce not only short saccharides but also disaccharides, etc. singly or as a mixture, or as a mixture of these saccharides or candy and chewing gum base. It has become possible to easily obtain good cotton candy fibers only when various materials such as those mentioned above are used as raw materials.
