TH23643U - Smokeless coffee bean roasting machine - Google Patents

Abstract

The coffee bean roasting machine using a smokeless clay jar according to the present invention consists of an outer jar of 90 liters that serves as a drying chamber. By installing an infrared burner set as a heat source. with sensor Automatic heat control. Inner jar, size 8 liters, is rotary. Equipped with a rotating mechanism to control speed, using a motor to transmit rotational force and an automatic pouring system to roast coffee beans and having a smoke removal and heat circulation system. By observing the ripening of the coffee beans from the lid of the jar. Until the coffee beans are the color you want. Open the lid to pour the coffee beans onto the tray. which is equipped with a cooling kit using a motor as a drive Keep rotating to cool the coffee beans. It has a control system for all operations using a microcontroller and Sensor system And the bottom part of the smokeless clay pot coffee roaster is the base and wheels for moving.

Claims (1)

1. Smokeless coffee bean roasting machine It consists of an outer jar (1) placed on a machine stand (14), a closed rectangular shape with wheels mounted on it. The raised upper part of the base is used to support the inner jar (2) and the outer jar (1). The inner jar (2) is installed inside the outer jar (1) with stainless steel fins (3). Installed inside the inner jar (2). The inner jar protection part (2) is connected to the motor (4) for roasting coffee beans, which uses 200 watts of direct current, which penetrates the sides of the two said jars. The direction of rotation of the inner jar (2) works with the stainless steel fin plate (3) to allow the coffee beans to receive evenly heated and helps in pouring coffee beans out of the jar The inner clay jar (2) rotates clockwise while roasting coffee beans. and counterclockwise When taking coffee beans out of the jar by controlling the rotation and speed of the motor (4) roast coffee beans From the control box (5) which uses a microcontroller to command operations. The unique feature is that the control box (5) is installed on the left side of the said structure and looks like a rectangular box. Control the rotation and adjust the speed of the motor. (4) Roast coffee beans and can control the operation of Lighting and extinguishing from an infrared burner (8) to control the temperature of coffee roasting. which can be set The temperature value is obtained from the control box (5) with a temperature sensor installed on the inside side of the outer jar (1) to check the temperature as set. The control box (5) also commands the motor (12) to operate. Receiving tray (6) When coffee beans come out of the jar, the motor (12) receiving tray (6) is installed at the front of the outer jar (1) connected to the spatula (13) to stir the temperature inside the coffee beans. To cool down, the outer jar (1) which is located on the base of the machine (14) serves as a heat source for the inner jar (2). On one side of the said outer jar, there is a hole (7). To allow the heat from the infrared burner (8) to spread the heat. The top of the outer jar (1) also has a pipe (9) connected to the heating chamber for heat transfer. It is a renewable energy. And also burn the smoke to reduce the amount of smoke. And it is also more complete combustion which has a valve to control the amount of smoke entering the combustion chamber The moisture drainage pipe (10) which is connected to the back of the outer jar (1) and has a jar cover (11) is assembled in front of the said outer jar (1).
