Baker using electromagnetic mode to heat coffee bean

Abstract

The invention discloses a baker using an electromagnetic mode to heat coffee beans; the baker comprises a machine body (1), a roller (2) and a cooling device (3); a motor (11) and a controller (12) are arranged in the machine body (1); the roller (2) is connected with the motor (11), and comprises a roller body (22), a heater (21) and a case (24); the heater (21) comprises electromagnetic bodies (23) uniformly arranged on an outer periphery of the roller body (22) in a circumference direction; the roller body (22) is made of magnetic conductive metal material; the surface, contacting with the roller (2), of the electromagnetic body (23) is made of microcrystalline glass material. Heat can be generated by electromagnetic between the electromagnetic body (23) and the roller body (22) so as to heat the coffee beans in the roller; the baker is simple in structure, high in thermal efficiency, and the temperature in the roller can be easily controlled.

Description

technical field [0001] The invention relates to a roasting device for coffee beans, in particular to a roaster for heating coffee beans in an electromagnetic manner. Background technique [0002] Coffee beans contain a variety of nutrients and have a unique flavor. In the process of making coffee, the coffee beans need to be roasted through a roasting device. The high temperature generated during roasting evaporates the water contained in the raw coffee beans, so that the coffee beans Gradually caramelizes during the dehydration process, enhancing the flavor and mouthfeel of the coffee. [0003] The coffee bean roasting machine in the prior art generally includes a combustion chamber, which is provided with a drum for placing coffee beans and a stove for heating the drum. Generally, the stove is heated by heating elements such as gas combustion or resistance wire, and the gas is heated. There are potential safety hazards. Heating elements such as resistance wires heat the d...

[0003] The coffee bean roasting machine in the prior art generally includes a combustion chamber, which is provided with a drum for placing coffee beans and a stove for heating the drum. Generally, the stove is heated by heating elements such as gas combustion or resistance wire, and the gas is heated. There are potential safety hazards, heating elements such as resistance wires heat the drum, and the heat dissipation and heating are slow, the thermal efficiency is low, and the temperature is not easy to control
