A tea drying device

Abstract

The invention provides a tea leaf drying device and belongs to the field of mechanical equipment for tea processing. The tea leaf drying device comprises a fuel storage bin, a first air blower, a boiler, a drying box, a charging device and a leaf storage bin; the first air blower is connected with a dehumidifying device, then, the dehumidifying device and the fuel storage bin are separately connected with the boiler, and the boiler is connected with the drying box; the leaf storage bin is sequentially connected with the charging device and the drying box; a heat exchange pipe is arranged on the internal wall of the boiler and is provided with a heat exchange pipe open end and a heat exchange pipe outlet end, and the heat exchange pipe open end and the heat exchange pipe outlet end are separately connected with the dehumidifying device and the drying box; the drying box is provided with a hot air inlet end and a hot air outlet end, and the hot air inlet end and the hot air outlet end are connected with each other through a hot air circulating pipe; a second air blower is arranged on the hot air circulating pipe. According to the tea leaf drying device, the influence on a fuel combustion process and a tea leaf baking process caused by air moisture can be eliminated, the fuel combustion efficiency and tea leaf baking efficiency are increased, and energy is saved.

Description

【Technical field】 [0001] The invention relates to the field of tea processing machinery and equipment, in particular to a tea drying device. 【Background technique】 [0002] In the tea production process, the tea leaves need to be thoroughly dried and dehydrated to ensure that the taste of the tea leaves will not be lost, and at the same time, the storage time of the tea leaves can be extended. The drying methods currently used in production mainly include drying, frying, drying, etc., and the mechanical equipment used includes dryers, frying machines and drying auxiliary equipment. Among the above methods, the drying operation has the longest application history, but it has been gradually eliminated due to the shortcomings of obvious environmental constraints and poor product flavor quality, while the drying and frying operations are the most widely used in existing production. The flavor quality has its own characteristics. Among them, the frying and drying process is cond...

AI Technical Summary

Problems solved by technology

The higher the air humidity, the more heat required for fuel combustion, the slower the tea drying speed, and the lower the fuel combustion utilization rate, the more fuel is required for the tea drying process, which will seriously affect Operating cost of tea drying equipment
