Device for fully baking tea leaves and baking process thereof

Abstract

The invention relates to the technical field of tea leaf baking treatment processes, and particularly relates to a device for fully baking tea leaves and a baking process thereof. The device comprises an outer cylinder for heating, wherein a conical heating inner cylinder is reversely and rotationally arranged in the outer cylinder; a rotating turning part is arranged between the outer cylinder and the inner cylinder; the inner cylinder and the turning part synchronously rotate; a screw rod is rotationally arranged in a position, near the bottom, of the inner wall of the inner cylinder; and the turning part drives the screw rod to rotate around the self axis of the screw rod through a bevel gear set. The device performs primary preheating treatment on the tea leaves through the rotating inner cylinder and the screw rod having rotating direction opposite to the rotating direction of the inner cylinder in the inner cylinder, performs turning baking by means of the rotating turning part in the outer cylinder, meanwhile, adopts cooperation between first scraping teeth and second scraping teeth on turning blades to realize lifting, turning and lateral pushing of the tea leaves. Therefore, a traditional conveying belt type conveying structure is replaced, and high space utilization rate is achieved.

Description

technical field [0001] The invention relates to the technical field of tea roasting treatment technology, in particular to a device for fully roasting tea leaves and a roasting process thereof. Background technique [0002] Tea is a traditional drink in my country. The production of tea mainly includes processes such as spreading, drying, kneading, rolling, sieving and drying. The temperature can be as high as 250-270°C. Existing tea roasting machines only rotate and roast the tea leaves once, that is, complete the roasting of the tea leaves, resulting in the fact that some tea leaves have not been completely roasted, and need to be re-heated and roasted again; The long-line body baking method is adopted, and most of them are linear body structures. After this kind of equipment is put into operation, it will occupy a long space in the factory area, and the cost of the equipment is relatively large, so the application of the equipment is also limited.
