Tea drying machine

Abstract

The invention relates to the technical field of tea production equipment, in particular to a tea drying machine. The tea drying machine comprises a drying oven. Multiple groups of tea drying mechanisms are mounted in the drying oven of the tea drying machine. A tea conveying mechanism is arranged on each tea drying mechanism so that continuous circulating conveying of tea can be achieved. A rotating mechanism is mounted on one side of each tea conveying mechanism so that conveying pipelines can be rotated while the tea is conveyed. In this way, uniform turning and mixing of the tea are achieved; each conveying pipeline is sleeved with multiple heating rings, and the tea can be heated and dried in the tea conveying process; through continuous conveying, the tea is turned in the conveying process and is heated and dried in the turning process, and high efficiency and high uniformity drying effects can be achieved; and layered drying is adopted for the device, the drying temperature of each layer is not consistent, the tea is gradually dehydrated through different conveying layers, the quality of the obtained tea is higher than that of tea dried in a constant temperature state, and the tea drying machine has the extremely high practicability.

Description

technical field [0001] The invention relates to the technical field of tea production equipment, in particular to a tea drying machine. Background technique [0002] Drying is the last process of raw tea processing, and it is also one of several key processes. The main purpose of drying is to lose the moisture of the tea, shape the tea and increase the aroma of the tea, etc. The quality of the drying directly affects the quality of the tea. The drying equipment and methods used for drying different teas are different. For example, the traditional red tea is roasted and dried, which can be roasted in a baking cage or dryer; the traditional black tea is dried in a seven-star stove; The tea baking process is very meticulous, mainly including manual baking and mechanical baking. But no matter what kind of tea is made, which drying equipment and method is used, temperature is the main factor affecting the quality of drying; and development play an important role. Drying is no...

Problems solved by technology

The cold air blown by the fan enters the oven after being heated by the hot air equipment, and the hot air dries the tea leaves and directly discharges them out of the oven. During the drying process, the temperature of each part in the oven is basically kept the same. The drying quality of the continuous incoming tea leaves is average. In view of this defect, the Chinese invention patent application number 201610792152.9 proposes a layered temperature-controlled tea dryer. The dryer adopts multi-layer continuous drying. The drying mechanism is set, and a hot air generator is installed inside the device, which is transported to each drying layer through multiple hot air channels, and the drying temperature of each layer is controlled by the air volume valve, so as to achieve the drying effect layer by layer. Layers are gradually dehydrated, and the aroma components produced in the state of layered drying of tea leaves are higher than those produced in the state of constant temperature drying, thereby improving the quality of tea leaves. However, there are still certain defects in the design process of the device. The hot air channels on each layer are placed horizontally, parallel to the tea conveying layer, and the tea leaves are stationary when conveyed on the conveying layer, which leads to the inability of the tea to achieve a high drying rate during the drying process. Uniformity, there may be agglomeration of tea leaves during the drying process, which will affect the quality of tea leaves
