Continuous frying leaf device and pot stir tea production facility

摘要

PROBLEM TO BE SOLVED: To enhance tea making quality by again roasting leaves at a high temperature in a leaf re-roasting cylinder by utilizing the remaining heat of the combustion gas of a cylinder for carrying out oxidase deactivation and by incorporating the continuous rough rubbing device effectively utilizing the combustion gas from a leaf roasting process to enhance not only heat efficiency but also leaf roasting processing capacity.;SOLUTION: A continuous leaf roasting apparatus is constituted so that the leaf re-roasting cylinder 10 is arranged above a cylinder 8 for carrying out oxidase deactivation in the heating chamber 14; a plurality of gun type burners 15 for heating the cylinder 8 for carrying out oxidase deactivation from below are arranged to the lower part of the heating chamber 14 so as to leave an interval; the heating chamber 14 and the continuous rough rubbing device 9 are allowed to internally communicate with each other by a communication duct 16 so as to be capable of introducing the hot air in the heating chamber 14 into the continuous rough rubbing device 9; the cylinder 8 for carrying out oxidase deactivation and the continuous rough rubbing device 9 are connected by a first vertical bucket conveyor 12 for feeding the roasted leaves, which are subjected to oxidase deactivation in the cylinder 8, to the continuous rough rubbing device 9; and the continuous rough rubbing device 9 and the leaf re-roasting cylinder 10 are connected by a second vertical bucket conveyor 13 for feeding the roughly rubbed leaves in the continuous rough robbing device 9 to the leaf re-roasting cylinder 10.;COPYRIGHT: (C)2012,JPO&INPIT
