In existing steam fixation equipment, the tea leaves do not come into sufficient contact with the steam, resulting in low fixation efficiency.
A novel steam-based tea fixing device was designed, which uses a fixing drum and a drive mechanism. The inner wall of the drum is equipped with raised strips and is set at an angle. The drive mechanism causes the tea leaves to tumble inside the drum. Combined with a steam distributor and a recovery device, it ensures that the tea leaves and steam are in uniform contact.
This improves the contact efficiency between tea leaves and steam, enhances the withering efficiency, avoids the stacking of tea leaves, and ensures that the appearance of the tea leaves is not damaged.
