Abstract

This invention discloses a microwave coffee bean roasting device, comprising: a metal housing; a microwave heating cavity disposed in the upper half of the interior of the metal housing, the surface of the microwave heating cavity having a plurality of microwave power sources, and a spiral stirring mechanism and a temperature sensor disposed within the microwave heating cavity; a conical feed hopper disposed in the upper surface of the interior of the metal housing, the bottom of the conical feed hopper being connected to the microwave heating cavity; a discharge module disposed within the metal housing, located below the microwave heating cavity; an electronic control module disposed in the lower half of the interior of the metal housing, electrically connected to the microwave power sources; and a human-machine interface module disposed on the surface or exterior of the metal housing, electrically connected to the electronic control module. The microwave coffee bean roasting device according to this invention can rapidly heat large quantities of granular material, achieving rapid and uniform heating.

Claims

1. A microwave coffee bean roasting device, comprising: A metal casing; A microwave heating cavity is disposed in the upper part of the interior of the metal housing. The microwave heating cavity includes an air inlet and an air outlet. A plurality of microwave power sources are disposed on the surface of the microwave heating cavity to provide microwave power. A spiral stirring mechanism is disposed inside the microwave heating cavity to agitate the granular material to be heated for uniform heating. A temperature sensor is disposed above the microwave heating cavity to sense the temperature of the batch of granular material. A conical feed hopper is disposed on the upper surface of the interior of the metal housing. The bottom of the conical feed hopper is connected to the microwave heating cavity for feeding a batch of granular material. The material is fed into the microwave heating cavity for microwave heating. A movable metal plate is located above the conical feed hopper to close the conical feed hopper. A discharge module is located inside the metal housing, below the microwave heating cavity, to receive the batch of granular material heated by the microwave heating cavity. An electronic control module is located in the lower half of the metal housing. A human-machine interface module is located on the surface or outside of the metal housing and is electrically connected to the electronic control module to provide the operator with process parameters such as microwave power, microwave time, and heating temperature to notify the electronic control module to control the switching of the microwave power sources.

2. The microwave coffee bean roasting apparatus as described in claim 1, wherein, These microwave power sources are two sets of 1kW microwave power sources.

3. The microwave coffee bean roasting apparatus as described in claim 1, wherein, The discharge module is a removable support plate.

4. The microwave coffee bean roasting apparatus as described in claim 1, wherein, An electric heater is installed in the lower half of the metal casing to generate hot air, which enters the microwave heating cavity through the air inlet.

5. The microwave coffee bean roasting apparatus as described in claim 1, wherein, The lower half of the metal casing is equipped with a blower connected to the air outlet of the microwave heating cavity, which is used to extract waste byproducts inside the microwave heating cavity.

6. The microwave coffee bean roasting apparatus as described in claim 1, wherein, The microwave heating cavity is further equipped with a sound sensor, which is electrically connected to the electronic control module. The sensor is used to detect the popping sound generated when the batch of granular materials is microwave heated in the microwave heating cavity, and transmit the popping sound information to the electronic control module.
