Next, the structural features and operations of the first embodiment of the present invention will be described in detail in the following manner with reference to the drawings.
First, please refer to FIGS. The present invention is a structure of a kind of coffee bean roasting machine, which includes the following.

  There is a roasting chamber 10 surrounded by a single hollow wall plate, and there is a storage space in the roasting chamber 10, and a drawer type chaff box 11 that receives a thin skin of one material at the bottom of the storage space. In order to make it easier to pull out the chaff box 11 at the outer end of the chaff box 11, a handle 111 is provided, and the chaff box at the bottom of the front and rear side walls is provided inside the roasting chamber 10. A pair of heating pipes 12 are provided at locations close to 11, a vent hole 13 is provided on the side wall near the heating pipe 12, and a movable lid is provided at a location close to the vent hole 13. Since the plate 131 is provided, the air holes 13 can be sealed or opened for air by adjustment, and the reflector 121 is provided at the bottom of the heating pipe 12, so that the hot air can be easily guided upward. In addition to this, after the opening end of the roasting chamber 10 respectively A flip-up top lid 14 is pivoted on the edge of the filter side, and a pull button 141 is fixedly attached to the front end of the top lid 14, making it easy to open the top lid 14; symmetrical on both sides of the roasting chamber 10 The large and small U-shaped retaining grooves 15 and 16 are provided, and the symmetrical sliding rollers 17 are provided between the hollow wall plates of the large and small U-shaped retaining grooves 15 and 16, respectively. The symmetrical sliding roller 17 protrudes from the bottom edge of the retaining grooves 15 and 16 at the opposite upper oblique angle, so that it rotates more smoothly when the roasting cylinder 20 is rotated. In it, there is a gas guide hole 151 in the outer wall corresponding to the larger U-shaped retaining groove 15 of the roasting chamber 10, and when the roasting cylinder 20 is placed and fixed, the material is taken in and out The mouth of the pipe 22 can be just aligned with the gas guide hole 151, which generally seals two-thirds of its bottom. Presented in a circular hole that is chained, it mainly functions as heat dissipation, and has the function of closing the mouth of the material take-in and pipe 22 half, while the material in the roasting cylinder 20 rotates, It can be prevented from falling.

  A roasting cylinder 20 having a large number of one minute hole 21 is placed in symmetrical stop grooves 15 and 16 of the roasting chamber 10, and one end in the axial direction of the roasting cylinder 20 has a slightly U-shaped stop groove. It is converged to a material take-in / pipe 22 smaller than a width of 15 so that a material such as coffee beans can be filled or taken out of the roasting cylinder 20 from the material take-out / pipe 22 and the support shaft 23 extends in the axial direction of the other end. The support shaft has an umbrella gear 24 at the end of the support shaft, and one grip bar 25 can be extended from the shaft end of the umbrella gear 24 so that it can be gripped by hand. 20 can be removed from the roasting chamber 10.

One electric chamber 30 is provided on the outer side of the roasting chamber 10, one fan 31 and one transmission mechanism 32 are attached inside the electric chamber 30, and one electric chamber 30 is provided on the outer side of the electric chamber 30. There are two power sockets 33; among them, the transmission mechanism 32 is formed by connecting one umbrella gear 322 to the end of the transmission shaft of one reduction motor 321, and the umbrella gear 322 The roasting cylinder 20 can be connected to the rotation because the umbrella-shaped gear 24 of the roasting cylinder 20 is engaged with each other vertically.
There is one controller 40, which can be connected to the power socket 33 through the power connection line 41, and also has a power switch 42, a fan power switch 43, a heating pipe temperature setting button 44, and a transmission mechanism switch setting button 45. .

  The above parts assemble a home-style coffee bean roaster that is compact in volume.

  When carrying out the structure of the present invention, since the roasting cylinder 20 can be taken out from the roasting chamber 10 alone, further materials such as coffee beans or peanuts are put into the roasting cylinder 20 from the material take-in / out pipe 22 of the roasting cylinder 20. When it is easy to fill and the roasting cylinder 20 is placed again on the two stop grooves 15 and 16 that are symmetrical to the roasting chamber 10 to restrict the position, the roasting cylinders 20 in the symmetrical stop grooves 15 and 16 become opposite to each other. The sliding roller 17 can be stopped by coming into contact with the peripheral surfaces of the material take-in / out pipe 22 and the support shaft 23, respectively. A roasting cylinder is provided with a ring groove 231 in which the sliding roller 17 can be hooked and the side of the concave ring groove 231 is stopped outside the small U-shaped stop groove 16. 20 positions can be limited Also, the transverse umbrella type 24 and the umbrella type gear 322 of the transmission mechanism 32 can be engaged with each other by vertically intersecting, and then the power switch 42, the fan power switch 43, the temperature setting button of the heating pipe 44 and the switch setting button 45 of the transmission mechanism 32 can be sequentially activated, and the temperature of the heating pipe 12 and the rotation speed of the transmission mechanism 32 are set, and the roasting cylinder 20 is fixed by the transmission mechanism 32. The coffee beans put in the roasting cylinder 20 can receive heat uniformly, and air is introduced into the electric chamber 30 to dissipate the heat by the fan 31. When sent from the chamber 31 through the vent hole 13 into the roasting chamber 10, a circular circulating airflow is formed in the roasting chamber 10, and the temperature inside the roasting chamber 10 is maintained at a constant constant temperature. Effectively shortening roasting time Reached thereby proceeds.

  Also, while materials such as coffee beans or peanuts continually roll and collide in the cylinder 20, fine debris such as thin skins, embryos, or ruptured fruits always fall out of the micropores 21 in the cylinder 20, further When collected together by the chaff box 11 at the bottom of the roasting room 10, it becomes convenient for cleaning and the effect of simplifying the maintenance is contained.

  As shown in FIGS. 5 and 6, the roasting cylinder 20 according to the second embodiment of the present invention has a large number of fine holes 21 distributed in the hollow body and is provided with inclined notches 26 that are parallel to both sides. In addition, both the notches 26 converge outwardly to a conical cover 27 having a small diameter in the direction of the central axis, and one material inlet / outlet pipe 22 extends and is connected to one end of both conical covers 27. One end of the support shaft 23 is connected to the other end, and one end of the support shaft 23 is similarly provided with an umbrella gear 24 and a grip bar 25 in sequence.

  When the roasting cylinder 20 in the second embodiment is operated, the oblique angle and the length formed at all angles are different due to the rotation of the symmetrical cone-shaped cover 27, so that the roasting material itself rolls. The effect with automatic stirring.

  However, since what has been described above is only a better feasible example of the present invention, the structural scope of the present invention is not limited, so any structural changes that achieve the same effect are within the technical scope of the present invention. And should be guaranteed within the scope of the utility model registration request.

  In summary, the implementation of the structure according to the present invention certainly has a new creation and improvement of the actual effect, so it matched the gist of the establishment of the new patent. I would be pleased if the establishment of
