First, the term'food ingredient' used throughout the specification refers to various food ingredients that can be cooked or pre-cooked by heating, and is not limited thereto, but is not limited to pork, beef, chicken, duck, potato, corn, Ingredients such as beans, chestnuts, spinach, bracken, bean sprouts, bean sprouts, bean sprouts, bellflower, millet, rice cake, etc.

In addition, although the term'heating means' used throughout this specification describes cooking utensils using gas for the sake of concreteness and convenience of description of the invention, the same inventive idea is also applied to cooking utensils using electricity or other fossil fuels. As it can be applied as a method, it does not exclude cookware using other fuels.

In addition, the term "heating device" is defined to mean a device capable of heating cooking or pre-heating in various ways, such as baking, blanching, roasting, boiling, or frying, depending on the kind.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is an overall configuration diagram of a food material heating device 1 according to the present invention, FIG. 2 is a view showing a driving unit 10 of the food material heating device 1 of FIG. 1, and FIG. 3 is a food material heating device of FIG. It is a figure showing the discharge guide 50 of (1), and FIG. 4 is an exemplary longitudinal sectional view showing the internal structure of the drum 20 of the food material heating device 1 of FIG. 1, and will be referred to together for convenience of description.

The basic configuration of the food material heating device 1 according to the present invention is a drive unit 10, a rotatable drum 20, a screw 30 located inside the drum 20, a hopper 40, and a discharge guide ( 50), and a heating means 60 for heating the drum 20.

The above-described drive unit 10 includes a drive shaft 14 and a drive gear 15 connected to the motor 11 and the reducer 12, and a driven gear 17 linked by the drive gear 15 and the chain 18. It includes a set of pulleys 23 installed at both ends of the driven shaft 16 to which the is connected, and another set of pulleys 23 installed at spaced positions facing each other with the set of pulleys 23 described above.

On the other hand, the drum 20 has food material introduction ports 24 and discharge ports 25 formed at the centers of both sides of the main body 21, and flanges 22 are formed at both ends of the main body 21.

The drum 20 is rotatably supported by the four pulleys 23, which are fixed to the bottom frame (not provided with reference numerals) by the flange 22.

In addition, a screw 30 for stirring and transporting food ingredients is located inside the drum 20, and one end of the screw 30 is connected to the drive shaft 14 of the driving unit 10. do.

Therefore, when the drive shaft 14 rotates by the motor 11, the screw 30 connected to the drive shaft 14 rotates in the same direction, while the drive gear 15 connected to the drive shaft 14 The driven gear 17 also rotates in the same direction by the chain 18, and a set of pulleys 23 installed therein also rotates in the same direction as the driven shaft 16 connected to the driven gear 17 rotates. , The flange 22 engaged with the pulley 23 rotates in the opposite direction, and as a result, the drum 20 rotates in the opposite direction unlike the rotation direction of the screw 30, 20) The ingredients inside are uniformly and efficiently stirred and mixed.

A set of pulleys 23 connected to the driven shaft 16 and the other set of pulleys 23 installed at a spaced position opposite to each other are driven by the rotation of the flange 22 of the drum 20 in the opposite direction. It rotates in the same direction as a set of pulleys 23 connected to (16).

As a result, the drum 20 rotates by the rotation of a set of pulleys 23 installed on the driven shaft 16 described above.

A heating means 60 is positioned below the drum 20 to heat the food materials inside the drum 20, and the heating means 60 may be a multi-heat flat gas burner, but an electric heater Or, of course, it may be a burner using a far-infrared ray heater or other fossil fuel.

In addition, depending on the cooking method, water or cooking oil may be added to the inside of the drum 20 within a range that does not overflow through the discharge port 25, and then ingredients to be boiled or fried may be added.

On the other hand, the hopper 40 is detachably installed in the inlet 24 of the drum 20, and a discharge guide 50 is installed in the outlet 25.

The discharge guide 50 may be formed as a cylindrical network or a linear body for rapid air cooling of the heated food material.

Therefore, after the food ingredients introduced into the hopper 40 are introduced into the rotating drum 20 in a heated state by the heating means 60 through the introduction port 24, the rotation of the screw 30 Accordingly, it is continuously conveyed while being continuously heated toward the discharge guide 50.

At this time, the rotation directions of the drum 20 and the screw 30 are configured to be opposite to each other for uniform stirring, mixing and heating of the food materials in the drum 20.

Next, referring to FIG. 4, the configuration of the screw 30 inside the drum 20 will be described in more detail.

The screw 30 has a hollow shaft 32 and a continuous screw blade 31 of a wave shape integrally formed with the hollow shaft 32.

In the present invention, by selectively forming a plurality of scrapers 32 at predetermined intervals on the screw blades 31 described above, the food ingredients located under the drum 20 can be more efficiently pumped upwards. , It is effective to install the scraper 32 so as to form an angle of about 30 degrees with respect to the edge surface of the screw wing 31.

On the other hand, a plurality of nozzle holes 34 are formed in the hollow shaft 32 of the screw 30, and the drum 20 inlet 24 side of the hollow shaft 32 is in the drive shaft 14 It is coupled and closed, and a steam injection cap 33 and a temperature gauge 35 are installed at the discharge port 25 of the drum 20, and a probe 36 for temperature sensing is provided at the temperature gauge 35. Along one hollow shaft 32, it extends long toward the inlet 24 of the drum 20.

Therefore, when the ingredients in the drum 20 are boiled using steam or the inside of the drum 20 and the screw blades 31 are cleaned or cleaned, a steam hose (not shown) is connected to the above steam injection cap and then steam The high-pressure steam passing through the hollow shaft 32 of the screw 30 can be injected through the nozzle hole 34 by injecting it at high pressure.

Here, the nozzle hole 34 is formed to have a distribution that gradually increases in number from the discharge port 25 side of the drum 20 toward the inlet port 24, so that the drum 20 toward the inlet port 24 It is possible to effectively clean the part.

In addition, washing or washing of the drum 20 may be performed by rotating the screw 30 while injecting washing water through the hopper 40 or the inlet 24.

The food material heating device 1 according to the present invention may be installed in a rectangular frame (not provided with a drawing number) and configured as a box-type device to which an outer skin finish is attached, and a single or double door can be installed in a hinge structure on the front, (10) A control panel (not shown) may be installed on the outer shell of the side, a hood (not shown) may be installed on the upper part of the frame, and a caster may be installed under the frame to improve the convenience of moving the position. Yes, of course.

In addition to the present invention, depending on the type of food to be heated and the cooking method, the heating power of the heating means 60 is adjusted by the temperature gauge 35 to select a predetermined temperature, and rotation of the screw 30 By controlling the speed, by adjusting the retention time of the food ingredients in the drum 20, it is possible to provide a large amount of food ingredients continuously, effectively and efficiently, in a short time in a restaurant or in-house or on-campus cafeteria.

Although the present invention has been described in detail above, the present invention is not limited thereto, and various changes and modifications can be made therefrom by those skilled in the art, but this is also within the scope of the present invention.
