Claims (1)

1. Smokeless clay pot coffee roaster consisting of an outer pot (1) placed on a closed rectangular base with wheels mounted on it. The raised top of this base supports the inner pot (2) and the outer pot (1). The inner pot (2) is installed inside the outer pot (1), with stainless steel fins (3) installed inside the inner pot (2). The inner pot (2) is connected to a 200-watt DC motor (4) which is drilled through the sides of both pots. The rotation direction of the inner pot (2) works in conjunction with the stainless steel fins (3) to distribute the coffee beans evenly and to assist in pouring the coffee beans out of the pot. The inner clay pot (2) rotates clockwise while roasting the coffee beans and counterclockwise when removing the coffee beans, controlled by the rotation and speed of the coffee bean roasting motor (4). From the control box (5), which uses a microcontroller to control the operation, the specific characteristics are that the control box (5) is installed on the left side of the structure and is a rectangular box. It controls the rotation and speed of the coffee bean roasting motor (4) and can control the ignition and extinguishing of the infrared burner (8) to control the temperature of the coffee bean roasting. The temperature can be set from the control box (5), with a temperature sensor installed on the side inside the outer pot (1) to check the set temperature. The control box (5) also commands the motor (12) on the receiving tray (6) when coffee beans come out of the pot. The motor (12) on the receiving tray (6) is installed in front of the outer pot (1) and connected to a paddle (13) to stir and cool the temperature inside the coffee beans. The outer pot (1), which is placed on the base of the machine (14), acts as a heat source for the inner pot (2). One side of the outer pot is cut with a vent (7) to allow heat from the infrared burner (8) to spread into it. The top of the outer pot (1) is connected to a pipe (9) that leads to a heating chamber to transfer heat as renewable energy and also burn the resulting smoke to reduce the amount of smoke and to achieve more complete combustion. A valve controls the amount of smoke entering the combustion chamber. A moisture drain pipe (10) is connected to the back of the outer pot (1), and a pot cover (11) is attached to the front of the outer pot (1).
