Description

{A Roasting pan for coffee bean}

The present invention relates to a coffee roaster used for roasting coffee beans by hand, and more particularly, in a roaster with a conventional openable cover, it is necessary to open a cover opened during roasting to check the roasting state. However, A semi-open type ring-shaped cover is attached to the outside to effectively prevent the coffee beans from popping out during the roasting while allowing easy visual confirmation of the roasting condition of the coffee beans through the open part of the inside.

Generally, a manual coffee roaster is used for roasting coffee beans (green beans) of less than 1 kilogram (kilogram), making a net in the form of a frying pan (sometimes with a lid) .

On the other hand, in the conventional hand-operated coffee roaster described above, when there is no lid (cover), there is a problem that coffee beans are frequently outwardly caused by shaking operation during roasting, and when there is a lid, There is a problem that it is difficult to observe the subtle color change of the coffee beans during roasting, and since the lid is opened during the roasting to observe the color of the coffee beans, there is a fear that the heated ring may be caught by hand while being handled.

Conventional hand roasted coffee roasters are difficult to form irregular boundaries when the bottom of the pan is flat or the roots are formed in one direction (horizontal or vertical) so that the coffee beans are shaken for uniform roasting Or to shake only in a certain direction, so that the hands are clumped and the uniformity of the roasting is lowered.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a coffee bean which is easy to visually observe a subtle color change without causing a burning phenomenon during roasting of coffee beans, And to provide a coffee home roaster with an improved structure.

In order to achieve the above object, the present invention is characterized in that a semi-open type ring cover is attached to the outer side of a fan-shaped netting to effectively prevent the coffee beans from popping out during roasting, And a coffee roaster is provided.

In a specific embodiment, the coffee home roaster has a generally flat bottom surface and a side extending upwardly from the outer perimeter of the bottom surface, the top including an open net, a handle attached to a side of the net, And a ring-shaped cover formed along the outer periphery of the net so as to prevent the coffee beans from being lost to the outside of the net during the roasting.

In a preferred embodiment, the ring-shaped cover is made of a stainless steel plate or a stainless steel rim, and the ring-shaped cover is convex toward an intermediate upper portion.

In a preferred embodiment, a plurality of protrusions projecting to the top or bottom of the bottom surface are formed on the bottom surface of the net so that irregular bounds are formed on the coffee beans during roasting, and the protrusions are rotationally symmetric along the radial direction of the net So that uniform roasting can be achieved regardless of the shaking in any direction.

The present invention provides a semi-open type cover at the outer periphery of the netting to facilitate visual observation of the subtle color change of coffee beans while preventing the coffee beans from protruding without fear of opening and closing the cover during roasting and burning Therefore, it is possible to efficiently roast coffee beans, and even if the rotors are rotated in a rotationally symmetrical state on the bottom surface of the netting, the roasting is performed uniformly in any direction so that the fatigue to the hands can be minimized And the like.

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

1 to 6, the coffee roaster 100 according to the present embodiment includes a net 110, a handle 120 attached to the side of the net 110, And a ring-shaped cover 130 formed along the outer periphery of the net 110 so as to surround the upper periphery and preventing the coffee beans from being lost to the outside of the net 110 during roasting.

In the present embodiment, the net 110 is made of a stainless steel perforated plate, but the present invention is not limited thereto. The net 110 may be formed by forming a net into a pan and surrounding the net with a rim to be.

The net 110 has a generally flat bottom surface 112 and a generally upwardly extending side surface 114 at the outer perimeter of the bottom surface 112 and a top generally open pan in the form of a kitchen pan.

The bottom surface 112 of the net 110 has a middle portion protruding upward to a predetermined height in order to prevent the deformation of the bottom surface 112 (such as a sagging phenomenon or a twisting phenomenon due to the load of the contents) A plurality of protrusions 113 protruding to a lower portion of the bottom surface 112 are formed at an outer periphery of the intermediate protrusion 111. The protrusion 113 is formed by roasting When the floor surface 112 is flat, a large number of coffee beans flow together with respect to each other, so that irregular bounds are formed on the bottom surface 112 by the projections 113 protruding downward as in the present embodiment This allows the coffee beans inside the roaster to move outwards and the ones outside to move inward, thus allowing a uniform roasting of the coffee beans.

The protrusion 113 is formed to protrude downward from the bottom surface 112 of the net 110. However, the present invention is not limited to this, and the protrusion 113 may be formed in the same manner as the protrusion 111 on the inner side It may be formed to protrude from the top of the bottom surface 112.

In addition, the protrusions 13 may be formed by mixing protrusions that are downwardly and upwardly protruded. The protrusions 13 may also be formed in a garden or other various shapes in addition to a long oval shape as shown in the drawings. Of course it is.

Since the protrusion 113 is disposed in a rotationally symmetric state along the radial direction of the bottom surface 112, the protrusion 113 can be easily rotated by gripping the knob 120, shaking the roaster rightward or leftward, The same irregular bounding of the coffee beans produced by the same makes it possible to roast uniformly regardless of the skill or habit of the worker.

Also, in this embodiment, the ring-shaped cover 130 is made of a thin stainless steel plate as shown in the figure, but the present invention is not limited to this, and the ring-shaped cover 130 may be made of a stainless steel perforated plate or a stainless steel to be.

In the present embodiment, the ring-shaped cover 130 is not a flat ring shape as seen in the front view of FIG. 2 and the sectional view of FIG. 4, but a convex inclined surface 134 from the rim 132 of the outer periphery toward the intermediate upper portion (Roasted coffee beans, roasted coffee beans, roasted roasted roasted roasted roasted roasted roasted roasted roasted coffee beans, Shaped cover 130 to protrude toward the middle portion of the cover 110 and to be dropped toward the center of the cover 110. In addition, So that the coffee beans B move from the central portion of the net 110 to the outer portion and then collide with the ring-shaped cover 130 to return to the central portion of the net 110 so that uniform roasting is possible It is good.

On the other hand, in the present embodiment, the ring-shaped cover 130 has an opening 136 whose middle portion is opened upward, which allows the roaster to accurately confirm the roasting condition (color) of the coffee bean directly through this opened portion The existing roaster must be opened during roasting or visible through the mesh of the cover net so that there is a risk that the cover will be exposed when the cover is opened, There is a problem that the roasting is failed due to a confirmation or an excessive time is required for roasting.

In the present embodiment, the inner diameter of the opening 136 inside the ring-shaped cover 130 is formed to be substantially the same as the diameter of the bottom surface 112 of the net 110, When the inner diameter of the opening of the ring-shaped cover 130 is made larger than the upper limit, the upper limit of the parabola formed by the coffee beans bound to the upper portion of the ring-shaped cover 130 substantially coincides with the diameter of the bottom surface 112 of the net 110. In this case, If the inner diameter of the opening is made smaller than this, the coffee beans will not be shed, but it may become inconvenient to pour out the roasted coffee beans.

Meanwhile, in the present embodiment, the ring-shaped cover 130 is manufactured separately from the net 110 and is integrally coupled to the net 110 by spot welding or seam folding on the outside of the net. However, It is needless to say that the net 110 and the ring-shaped cover 130 may be integrally formed from a single perforated plate.
