Tea dynamic drying machine

Abstract

The invention provides a tea dynamic dryer, the structure includes machine rack, drum, outer cover shell, tea inlet bucket, the drum upon the machine rack is placed on the friction wheel and supporting wheel, the lower part of the tea inlet bucket is adapted to one end of the drum tea inlet dynamic-static interval, which is characterized in that: the other end of the air inlet pipe is connected to the hot air transmitting pipe through the floating pipe; the cross sectional area of the central air pipe is gradually reduced from the air inlet end; outer ring surface of the drum is longitudinally equipped with many bar shaped plates; the machine rack is equipped on the machine rack through the swivel-pin, the machine rack horizontal angle modulation mechanism is equipped between the machine base and the machine rack. Under the conditions that the tea is in dynamic, suspending state and is desiccated, the machine has the advantages as follows: the utilization rate of equal diameter drum useful space is high, the waste hot wind is not easy to resort around the drum, the hot efficiency is high, the running time of tea in the drum can be effectively controlled according to the processing demand.

Description

【Technical field】 [0001] The invention relates to the field of tea processing machinery, and is especially suitable for a tea dynamic drying machine used as the primary drying after tea leaves are rolled. 【Background technique】 [0002] The key to making green tea is color retention, and the primary drying machine after the tea leaves are rolled is the key to color retention. Existing dryers such as louver type and mesh belt type have the defects of dehydration, uneven color, inconsistent dryness and wetness, and poor quality because the tea leaves to be baked are spread on the drying net (board) and hot air is used for static drying. . Patent No. 01233806.0 "A Tea Dryer" discloses a machine that uses hot air to dry the tea leaves to be baked in a dynamic and suspended state. It is composed of a feed hopper, a heat source device and its hot air input pipe, and a transmission variable speed regulating mechanism. The perforated drum is in the shape of a hollow horizontal cy...

Problems solved by technology

[0003] However, the above-mentioned machinery still has the following deficiencies in actual use: the effective space utilization rate of the inner cavity of the drum is low, the waste hot air is easy to stay on the periphery of the drum, thereby affecting the drying effect, the waste hot air is directly discharged to the atmosphere, and the thermal efficiency is low. The walking time in the drum cannot be effectively controlled according to the process requirements, thus affecting the further improvement of tea quality
