Description

Coffee roasting apparatus for easy roasting operation

The present invention relates to a coffee roasting apparatus for heating and roasting green coffee beans.

In general, coffee is extracted after processing and roasting green beans.

The taste of coffee may change according to the processing of green beans, but the roasting operation is important because the taste changes depending on the roasting time and temperature of the coffee.

When roasting coffee, roasting must be performed while stirring so that the coffee can be heated evenly for a preset period of time. "Coffee bean roasting apparatus" of Korean Patent Registration No. 10-2212383 (notice on Feb. 4, 2021) has been disclosed.

The conventional coffee bean roasting apparatus includes: a roasting drum member for roasting the input coffee beans; a driving member for rotating the rotating body; a heat source member including a near-infrared module located on the outer side of the rotating body, and a temperature measuring module located inside and outside the rotating body; and a control member for controlling the driving member and the heat source member, wherein the control member controls the near-infrared irradiation condition of the near-infrared module according to the temperature value measured by the temperature measurement module, thereby controlling the roasting temperature, roasting could be conveniently performed.

However, in the conventional coffee bean roasting apparatus, because the roasting drum member is located only horizontally, it is not only somewhat insufficient to roast a large amount of coffee beans, but also when it is necessary to check the roasting state of the coffee beans during the roasting process, There was a problem in that it was difficult to check the overall roasting state of the beans because it can be checked only by taking them out.

In addition, since the roasting drum member cannot be separated, it is difficult to clean the roasting drum member after roasting.

The present invention has been devised to solve the above problems, and the problem to be solved by the present invention is to rotate the roasting frame in the main frame to easily change the direction of the inlet of the rotary drum and to perform the roasting operation. An object of the present invention is to provide a coffee roasting apparatus that not only facilitates taking out beans, but also roasts a large amount of coffee beans, and facilitates a roasting operation that can easily check the overall roasting state.

An object of the present invention is to provide a coffee roasting apparatus that facilitates a roasting operation that can be easily released.

In addition, as the spanning flange part of the rotary drum is released from the support roller, the rotary drum can be coupled and separated from the barrel driving part, so it is possible not only to clean the rotary drum, but also to attach the burner to the hanger frame. An object of the present invention is to provide a coffee roasting apparatus that is installed and can maintain a horizontal state even when the roasting frame is rotated, thereby preventing a fire accident due to inclination of the burner, which is easy to roast.

A coffee roasting apparatus for easy roasting according to an embodiment of the present invention for achieving the above object is formed with an inlet into which coffee beans are inserted is opened laterally, rotates around the inlet, and a plurality of perforated holes on the periphery The formed rotary drum, a barrel driving part for rotating the rotary drum, a burner positioned under the rotary drum to heat the coffee beans, the rotary drum, the barrel driving part, and a roasting frame in which the burner is installed, the roasting frame a body frame supporting the body frame, a body hinge part rotatably coupling the roasting frame in the body frame so that the inlet opening is upward or downward, and the roasting frame in the body frame around the body hinge part to easily rotate the roasting frame It includes a handle portion protruding from the roasting frame to be gripped.

The body frame may include a position limiting part for fixing the handle part in the body frame to rotate the roasting frame to fix the position in which the inlet faces in a changed state.

The handle portion may include a handle hinge portion rotatably coupled in the roasting frame to rotate left or right in the roasting frame to span the position limiting portion, or to release the hanging.

The roasting frame may include a hanger frame installed in the form of suspending the burner on the roasting frame so that the burner remains horizontal even when the roasting frame rotates in the main frame.

The body frame may include a burner support for supporting the burner to prevent the burner from shaking while the roasting frame is rotated so that the inlet is upward.

The roasting frame includes a support roller for rotatably supporting a circumference where the inlet of the rotary drum is located, and the rotary drum is detachably shaft-joined in the axial direction of the driving shaft of the barrel driving part for rotating the rotary drum. Shaft joint, or separating the rotary drum from the drive shaft when separated from the support roller, or spanning over the support roller to prevent the rotary drum from being separated from the drive shaft by spanning the support roller. can

According to the present invention, since the roasting frame is rotatably installed in the main frame, the direction of the inlet of the rotary drum can be changed according to the roasting operation, and the roasting operation can be easily performed.

In addition, it is possible to easily fix the position of the roasting frame in a form in which the handle part spans the position limiting part, and the handle part is rotatably coupled by the handle hinge part to facilitate the fixing and releasing of the fixing in the position limiting part. can be done
