Abstract
A roaster for roasting coffee beans includes a roasting chamber having a top and a bottom. A cover is seated on the top of the roasting chamber and a bottom of the roasting chamber is seated on a base. A hot air supply is provided in the base for supplying hot airflow into the roasting chamber for heating the coffee beans. At least one air opening is formed on the bottom for enabling the airflow to enter the roasting chamber. A wind tunnel is provided over the air opening for increasing the speed of the airflow in the roasting chamber as the airflow passes through the wind tunnel.
