Manufacturing kamairicha has proven difficult due to its low production capacity. To improve its capacity, a primary tea rolling dryer that has been used in the manufacturing of sencha was introduced. Based on the sencha process, an initial method for manufacturing kamairicha was developed: parching → primary tea rolling dryer → tea roller → secondary tea rolling dryer. Unlike steaming of sencha, parching is the first step of the kamairicha process for inactivation of enzymes in the tea leaves. In this case, falling rate drying period is apt to occur. To allow the moisture in the leaves to be uniformly distributed, we proposed a new kamairicha manufacturing process: parching → tea roller → primary tea rolling dryer → secondary tea rolling dryer. This new method allows the
