Full-automatic tea leaf drying device

Abstract

The invention provides a full-automatic tea leaf drying device, and belongs to the field of tea leaf processing mechanical equipment. The full-automatic tea leaf drying device comprises a fuel storage bin, a first draught fan, a boiler, a drying box, a feeding device and a leaf storage bin. The fuel storage bin and the first draught fan are connected with the boiler, and the boiler is then connected with the drying box. The leaf storage bin is sequentially connected with the feeding device and the drying box. A heat exchange pipe is arranged on the inner wall of the boiler and provided with a heat exchange pipe opening end and a heat exchange pipe outlet end which are connected with the first draught fan and the drying box correspondingly. The drying box is provided with a hot air inlet end and a hot air outlet end which are connected with each other through a hot air circulation pipe. The hot air circulation pipe is provided with a second draught fan and a hot air extension pipe which is provided with a first electromagnetic valve in a penetrating manner. The full-automatic tea leaf drying device can achieve automatic feeding, drying, discharging and cooling of the tea leaf drying process and can accurately control the drying degree of tea leaves and improve the tea leaf drying quality and drying efficiency, and the device is easy and convenient to operate.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of tea processing machinery and equipment, in particular to a fully automatic tea drying device. [0003] 【Background technique】 [0004] 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 fr...

Problems solved by technology

Among them, firewood and coal-fired equipment are relatively serious in environmental pollution, and it is easy to contaminate the tea with the smell of firewood and coal, seriously affecting the original taste of tea; the current drying effect of gas, oil and electric heating equipment is better, and the obtained tea leaves However, gas and oil-fired equipment have disadvantages such as high initial investment and poor temperature control stability, while electric heating drying equipment has low thermal efficiency and high operating costs.
