A heating mechanism of a coffee roaster and a processing process thereof

Abstract

The invention relates to a heating mechanism of a coffee roaster and a processing process thereof. The heating mechanism of a coffee roaster comprises more than one arc-shaped heating base arranged on the outer periphery side of a roasting oven. A U-shaped notch extending inward is formed in each of the two ends of each heating base; an arc-shaped vertical base used for supporting heating tubes is welded to the inner wall of each heating base and is close to each U-shaped notch; a plurality of transverse heating tubes are arranged in the circumferential direction in each heating base at intervals; the two ends of each heating tube are put on the vertical bases; the distance between the two vertical bases is less than or equal to the length of each heating tube; each vertical base is circumferentially provided with through holes in a matching penetration relationship with the heating tubes. The heating mechanism also comprises guide wires arranged at the ends of the heating tubes and electrically connected with the heating tubes. The guide wires penetrate through the through holes and extend to the outsides of the vertical bases. The roasting oven and the guide wires are arranged on the inner space and the outer space of the heating bases and are isolated, so that the probability of burnout of the guide wires is reduced and the service life of the heating tubes is prolonged.

Description

technical field [0001] The invention relates to the field of coffee roasting, in particular to a heating mechanism of a coffee roaster and a processing technology thereof. Background technique [0002] The heating mechanism of the existing coffee roaster is generally by setting the heating pipe on the inner wall of the heating seat, and the heating seat is sleeved with a baking furnace, and a part of the wire of the heating pipe is also located on the inner wall, and the other part passes through the heating seat wall. The through hole leads to the outside to connect to the power supply part. However, this structure causes the heating mechanism to produce a high temperature of 800-1000°C due to the heating tube, and the wire can only withstand a temperature of 100-300°C. Therefore, the existing heating mechanism causes the wire and the heating object (baking furnace ) in the same space, the temperature of the inner wall of the heating tube is too high, and the wire is easy ...

However, this structure causes the heating mechanism to produce a high temperature of 800-1000°C due to the heating tube, and the wire can only withstand a temperature of 100-300°C. Therefore, the existing heating mechanism causes the wire and the heating object (baking furnace ) in the same space, the temperature of the inner wall of the heating tube is too high, and the wire is easy to burn when the temperature exceeds 200 °C

Since many of the existing heating tubes are formed by integrally processing the heating tube, the stand and the heating tube wire, if the heating tube wire is blown out, the entire heating tube needs to be replaced
