Hot air recovery system of tea drying machine

Abstract

The invention discloses a hot air recovery system of a tea drying machine. The hot air recovery system comprises a hot air stove and a drying machine; the drying machine is communicated with an air outlet of the hot air stove through a first guide pipe; the hot air recovery system further comprises a second guide pipe and a third guide pipe; the top of the drying machine is provided with an air suction hood communicated with the top of the drying machine; and the air suction hood is communicated with a green leaf tedding chamber through the second guide pipe and communicated with an air inlet of the hot air stove through the third guide pipe; Both the second guide pipe and the third guide pipe are provided with regulation valves and draught fans. According to the hot air recovery system of the tea drying machine, disclosed by the invention, when temperature in a green leaf tedding workshop cannot reach at the requirements, the hot air in the hot air hood is discharged to the green leaf tedding chamber through the second guide pipe, and the discharged hot air is used for rapidly tedding tea leaves and effectively speeding up moisture loss in fresh leaves (in particular rainwater-contained leaves), so that the tedding time of tea leaves is shortened, the number of workers is reduced, the problems such as manpower shortage during the traditional processing of tea leaves are solved, and the utilization rate of heat is improved.

Description

technical field [0001] The invention relates to a hot air recovery system of a tea drying machine. Background technique [0002] Tea is a traditional drink in our country. The tea brewed with it can not only quench your thirst, but also have the effects of promoting body fluid, relieving heat, clearing heat, and detoxifying. Regular drinking can play a very good role in health care. Usually, the processing process of tea leaves includes greening, greening, rolling, and drying. The existing drying process is completed in the drying workshop. If it is not fully utilized, it will not only cause a waste of energy and increase the cost of tea production, but also cause a high temperature in the working environment, which will affect the work efficiency of the workers; tea spreading is an important process, and currently known tea spreading is generally done by The tea leaves are spread to a certain thickness so that the water in the tea leaves will be lost naturally. During this...

Problems solved by technology

Usually, the processing process of tea leaves includes greening, greening, rolling, and drying. The existing drying process is completed in the drying workshop. If it is not fully utilized, it will not only cause a waste of energy and increase the cost of tea production, but also cause a high temperature in the working environment, which will affect the work efficiency of the workers; tea spreading is an important process, and currently known tea spreading is generally done by The tea leaves are spread to a certain thickness so that the water in the tea leaves will be lost naturally. During this process, because the water cannot be dissipated in time, the temperature in the tea leaves will gradually rise. certain level

The above method needs to be equipped with certain staff members to manually turn over time in the batch production of tea, which is labor intensive and also increases the processing cost of the product
