Description

The useful model belongs to the equipment of the food industry, namely to the devices used for the production and sale of air corn - popcorn.

There are known devices for making popcorn, in the bottom of which an electric or induction heating element is mounted. Such devices have a body and a container installed with the possibility of turning relative to the body, in which the grain and fat are heated, if necessary, ingredients are added to it to form popcorn. For this, usually, a bent tubular heating element of resistive heating (patent 05 Mo 4649263) or an induction winding (patent OA Mo 96992) is placed inside the case between the inner and outer bottom.

At the same time, the container is located in the upper part of the case or on the supporting support (industrial machines) and is connected to the source of electrical energy (socket) by a conductive cable, which constantly bends during operation (emptying the container), as a result of which it becomes unusable and needs to be replaced. The heating element, which is located in the body of the container, does not allow the use of running water (immersion) during cleaning, as a result of which it is impossible to completely remove the remains of fats and soot. The patent (SHA Mo 76188, AI231/18) implements the possibility of using a heating element (electric and gas) separately from the container.

Patented devices are taken as analogs: "Popcorn-STARLINE universal device for making popcorn, which contains a body, a container for loading and mixing the components of the product and forming popcorn, a work table, a bottom, a heating system independent of the container (electric and gas heater ), and the control unit (patent of Ukraine

Mo 76188, Ag23II 11/18, 12/25/2012); "Apparatus for the production of popcorn with induction heating", which contains a body, a container placed in it for loading and mixing the components of the product and the formation of popcorn, a bottom on which the induction heating system is raised under a rotating container, and a control unit (patent Sho Mo 5928550,

A23I 11/18, 07/27/1999); "Apparatus for the production of popcorn with induction heating", which contains a housing, a container placed in it for loading and mixing the components of the product and forming popcorn, while for emptying, the container is made with the possibility of rotation relative to the housing, as well as a bottom, an induction heating system and a block management (patent of Ukraine Mo 96992, A23ZI. 1/18, 26.12.2011) - prototype.

The disadvantage of the apparatus according to the patent of Ukraine Mo 76188 is that the resistive heater, like others, requires preliminary heating of the element, for this it takes more time and electricity consumption to heat the container to the working state. A positive thing is the absence of heaters in the container, which makes it possible to immerse it in water to clean it of fat and soot.

The disadvantage of the design of another analogue (patent OB Mo 5928550) is that the round base of induction heating takes up a lot of space at the bottom of the device, which is provided for receiving popcorn, and makes it difficult to remove the finished product from the device, in addition to ensuring the ability to rotate the container in the upper part housing in the emptying position, a large distance is required between the bottom of the container and the induction heater, which weakens the alternating magnetic field created by the induction winding, and this requires a lot of current and time to heat the container to its working state. A positive thing is the absence of heaters in the container, which makes it possible to immerse it in water to clean it of fat and soot.

The disadvantage of the design of the device with induction heating according to the patent of Ukraine Mo 96992 is that the induction winding is located in the body of the container between the inner and outer bottom. In the device with a suspended capacity, which is located in the upper part of the structure, it is not possible to apply forced air cooling of the induction winding (such as a fan, which is necessary) and this does not ensure the effective use of induction heating, as well as a frequency converter (generator) located stationary in the case of the apparatus for making popcorn, is at a certain distance from the container for preparing the finished product and requires the connection of a special (protected) electrical power supply system, which complicates the design. At the same time, the container is located in the upper part of the device body and is connected to the source of electrical energy (socket) by a conductive cable, which constantly bends during operation (emptying the container), as a result of which it becomes unusable and requires replacement. The placement of the induction coil inside the container between the inner and outer bottom does not allow the use of running water (immersion) during cleaning, as a result of which it is impossible to completely remove the remains of fat and soot. In the container, the outer bottom to prevent heating consists of an electrical insulator with dia- or paramagnetic properties, which also complicates the design. The mixer is located in the upper part of the structure above the container.

In large popcorn machines with a container mounted above the receiving tub, on a supporting support, the induction coil is located inside the container, which has partial, one-sided, forced blowing (cooling) by a fan, as well as a frequency converter (generator) located stationary in the body of the device at a certain distance from the induction coil. The container is also connected to the source of electrical energy (socket) by a conductive cable, which in the process of operation (emptying the container) constantly bends, as a result of which it becomes unusable and requires replacement. In the container, the outer bottom to prevent heating consists of an electrical insulator with paramagnetic properties.

The mixer is located in the lower part of the supporting support, the drive shaft of which protrudes into the container from below, through the bottom, passing through the induction winding. Therefore, the shaft in the place of influence of the alternating magnetic field, as well as between the induction winding and the bottom of the container, must be surrounded by a shell of dia- or paramagnetic material, which adds complexity and additional costs to the design. Also, as the practice of operation has shown, the capacity for making popcorn with the drive shaft of the stirrer passing through the bottom of the container, in the further process of operation, causes oil to flow into the container between the inner and outer bottom at the place where the shaft passes, which in the future requires repair and replacement of parts in containers

The useful model is based on the task of making the well-known design of the apparatus for making popcorn with induction heating more economical and more convenient in service due to structural improvements of the installation and the use of an induction heating element, independent, separate from the container in which popcorn is made, with the location of a motor-reducer angular transmission of the stirrer on the side of the container, unlike those that use stirrers in other designs from above or below it.

The task is solved by the fact that in the apparatus with induction heating for the production of popcorn "WINGED POPCORN", which contains a casing, a container is placed in it for loading and mixing the components of the product and the formation of popcorn, while for emptying, the container is made with the possibility of turning relative to the casing, as well as a bottom, a work table, a heating system with an induction winding, a high-frequency generator and a control unit, according to a useful model, the heating system contains an induction heating element (induction coil), made independently, separately from the container and located under it on the work table. Or in an apparatus for making popcorn with a container mounted above the receiving bath on a supporting support (industrial machines), for emptying the container is made

With the possibility of turning relative to the body of the support, and the induction heating system, generator and control unit, the heating system contains an induction heating element (induction coil), made independently, separately from the container and located under it on the supporting support.

At the same time, the induction winding (coil) has radially located ferrite plates on the back side, a forced cooling fan, which is located below the winding in a paramagnetic material.

In addition, a high-frequency 20-60 kHz converter (generator) is located directly next to the winding and has an independent forced cooling fan.

In turn, the temperature sensor is located in the induction unit and passes through the induction winding, glass ceramic and protrudes above it in an air layer, touching the center of the multi-layer bottom of the container, with the possibility of setting the exact temperature regime for cooking popcorn with an adjustable control unit.

In addition, the container with a multilayer bottom is above the induction heating element and has an air gap between them without touching.

Also, the heating system control unit provides automatic power off of the induction heating element when emptying the container and automatic switching on when the container is returned to the working position for continued work.

In addition, the heating control system and design of the loading container allows loading and mixing of corn kernels, fat and food additives with the ability to make salted or caramel popcorn in the same machine.

And finally, the container for mixing grain, fat and other components is equipped with a stirrer, which has an angular drive from a motor-reducer located on the side of the container.

In the container for making popcorn, the multilayer bottom consists of a steel disk of magnetic steel, an aluminum or copper disk and placed in a capsule of stainless steel of ferrite class.

To prevent damage to the integrity of the multi-layer bottom of the container, an angular transmission of the stirrer rotation was applied.

In turn, as shown by the practice of operating the heating system of machines for the production of popcorn with induction heating "WINGED POPCORN", the time for preparing one load of popcorn was reduced by 3095 and the consumption of electrical energy by 35 95, compared to analogues with a resistive heating system.

The new features are listed above (the induction heating element is made independently, separately from the container and is located under it, a multi-layer, heat-accumulating bottom of the container, the motor-reducer of the angular transmission of the stirrer from the side of the container, forced cooling of the induction winding and frequency converter, work table), when interacting with known features (body, bearing support, heat-insulating bottom, container, agitator of upper or lower feed into the container, heating system, generator and control unit) ensure the detection of new technical properties of the useful model and increase the convenience in service, improved consumer properties, and namely: reliability and increase in the service life of the devices, ease of use, unlimited time of the continuous process of popcorn preparation, reduction of time for the production of one load and reduction of electricity consumption, the possibility of immersing the container in running water to clean it of fat and soot, operation in unstable conditions and the voltage of the electrical network, which does not affect the quality of the devices, the absence of the effect of heating the surrounding air, as with resistive or gas heating.

The drawings show the structural and technological diagrams of "WINGED POPCORN" popcorn machines with a view of two versions of their constructive implementation: in fig. 1 - a view of the device with induction heating in the case; in fig. 2 - a view of the device with induction heating on a supporting support; in fig. C - a method of emptying the container from ready popcorn; in fig. 4 - sectional view of parts and mechanisms of devices with induction heating.

The device consists of a body 1, the lower heat-insulating part (bottom) 2, the control unit C (Fig. 1) is placed in it, in the devices on the supporting support, the control unit is located on the side 3-a (Fig. 2), the work table 4 or supporting support 5, container 6, which has the shape of a pan for making popcorn with a multilayer bottom 20, induction heating unit 7, frequency converter (generator) 8, induction winding (coil) 9, glass ceramics 10, forced cooling fan 11, motor-reducer 12 , stirrer 13, angular transmission of rotation of the stirrer 14, container rotation mechanism 15, air layer 16 and 18, outlet air vents 17, temperature sensor 19.

In the "WINGED POPCORN" popcorn maker, the induction winding 9 contains

A spirally wound conductor made of copper wire, covered with a heat-resistant insulating varnish and located in the plane of the coil 9 on the base, which is located in the body of the work table 4 or the supporting support 5, above which a glass ceramic 10 is installed at a distance of 8 mm to protect the winding, which does not interfere with the passage through it, the alternating magnetic field and between them there is an air layer 16 with outlet ventilation holes 17, as well as forced cooling 11, which is located directly under the coil 9. To prevent the downward action of the alternating magnetic field on the metal parts of the case, the winding 9 has on the back side radially located plates of ferrite (not shown), therefore, to limit the effect of a weak, scattered magnetic field, the coil 9 and the fan 11, which is located below the winding 9 at a distance of 50 mm, are imprisoned in the paramagnetic material 7. The induction heating system 7, together with the control unit C (3-a), contains a high-frequency converter of 20-60 kHz connected to the induction coil 9 (generator) 8, located directly near the winding 9 and forcibly cooled by a fan 11. A mixer 13 is installed in container b for mixing grain, fat, and other components, which has an angle drive 14 from a motor-reducer 12. And the container itself has a multilayer bottom 20 and is located above the glass ceramic 10 at a distance of 8 mm and has an air layer 18. Thus, the container 6 is located at a distance of 20 mm above the induction coil 9, at the most permissible 30 mm for work, which provides stable, uniform heating of the multilayer bottom 20 of the container 6. For in order to prevent overheating of corn grain, fat and food additives in the container 6, the design of the "WINGED POPCORN" device is equipped with a temperature sensor 19, which is best installed in the center of the induction heating unit 7, the sensor 19 passes through the induction coil 9, air gap 16, glass ceramics 10, protruding in the air gap 18 and in contact in the center with the multilayer bottom 20 of the container 6 and connected to the block control C (3-a), for more accurate temperature setting (190 "C-195 "C - caramel or 210 "C-215 "C - salty popcorn) heating of the multilayer bottom of 20 containers b and keeping it within the specified limits. To make salted or caramel popcorn, the temperature is set separately on the control unit

З (З-а), in contrast to other designs, where the setting is set directly in the container itself (in specialized workshops), which cannot be done by the consumer himself during operation. The glass ceramic 10 does not heat up during the operation of the device, since the electric current passing through the coil 9 is transformed into an alternating electromagnetic field bo (eddy alternating induction current), which passes through the glass ceramic and affects the electrons of the ferromagnetic materials of the multilayer bottom 20 of the capacity b, which leads to the release of thermal energy directly in the bottom 20 of container 6.

The apparatus for making popcorn with induction heating "WINGED POPCORN" is used as follows.

Corn grains, fat, and food additives are loaded into the container b due to the existing stirrer 13, with the help of which the contents of the container 6 are mixed during heating, and thereby uniform heating of the corn grain and components is achieved to a state in which ready-made popcorn is formed, which under the influence of the stirrer 13 is transported to the top of the container 6 and falls down to the bottom of the heat-insulating part 2 of the apparatus (the receiving bath is not shown). At the end of the process, the finished popcorn is removed from the container b by turning (emptying) the container 6 (the rotary mechanism 15 is used) and the process is repeated again. During the rotation (emptying) of the capacity 6, the power supply of the induction coil 9 is automatically turned off and it does not work until the capacity b is returned to its working position, after which the power supply of the induction coil 9 is automatically turned on and the process is repeated.

During the production of caramel popcorn in container b, fat and food additives form a foam-like mass in which, when the grain is opened, the popcorn is covered with a thin layer of melted caramel and further, when it is unloaded onto the heat-insulating bottom of the 2 apparatus (receiving bath), it cools and forms caramel popcorn that does not contain moisture (as in the production of popcorn in caramelizers).

The practical use of the machine for making popcorn due to its design feature allows the consumer to work more comfortably to achieve his goal, to make salted or caramel popcorn at his discretion in the same machine, reducing the time for making one load of popcorn by 3095 and the consumption of electricity by 35 95.

The container for cooking popcorn, which is made independently of the heating element (induction coil) and is made of food-grade stainless steel with a multi-layered bottom, which gives an even distribution of the set temperature inside the container for the best quality of cooking products. Thus, the consumer has the opportunity to clean and wash the container with

With immersion under running water, which is not possible when using analogues.
