Tea hot air water-removing machine

Abstract

The invention provides a tea hot-air green removing machine, including drum and tea inlet bucket, the machine rack is placed on a stand which can adjust the horizontal angle of the machine rack. The inner cavity of the drum is divided into three functional areas of leaf pushing section, green removing section and desiccation section, the leaf pushing section is provided with guide-leaf plate and helix guide-leaf plate, and longitudinal central wind pipe. Part of the rampart of the central wind pipe and the closed surface are provided with small intensive hole; the green removing section is equipped with guide-leaf gluten, the centre shaft passage is equipped with wind cap; the desiccation section is equipped with guide-leaf gluten and many groups of spiral laminas, the drum wall on the tea inlet end is equipped with intensive air holes; interval dynamic-static connected wind wheel cover is equipped along radial direction on the tea outlet end, the upper part of the wind wheel cover is adapted to one end of return vent pipe, the other end of the return vent pipe is adapted to the inlet opening of the heat source device. The machine uses hot air to do the jobs of green removing and parching, the product has the merits of high thermal efficiency, sturdy leaves, good desiccation effect, and the green removing time of tea in the drum can be effectively controlled according to the tea producing methods.

Description

【Technical field】 [0001] The invention belongs to a tea making machine, in particular to a tea hot air degreening machine which uses hot air as a heat source and integrates degreening and drying into one. 【Background technique】 [0002] In the existing tea-making process, green-fixing machines mainly include wet and dry methods. Wet degreening uses water or steam as the medium, and the heat is transferred to the tea leaves for degreening, such as steam heat degreening machine, steam degreening machine, rinsing machine, etc. Dry deenzyming is to use the heated pot, cylinder, etc. as the medium, so that the fresh leaves can directly contact with the wall of the pot and cylinder to obtain heat to achieve the purpose of deenzyming. The above two methods have corresponding defects in practical application: the wet method can easily increase the water content of fresh leaves, and the next step can only be carried out after dehydration, which is not only troublesome but also incre...

Problems solved by technology

The above two methods have corresponding defects in practical application: the wet method can easily increase the water content of fresh leaves, and the next step can only be carried out after dehydration, which is not only troublesome but also increases production costs, and improper control will also affect the quality of tea leaves ; Dry greening fresh leaves are easy to scorched edges and bursting points, resulting in smoke burnt smell and affecting the quality of tea

However, through continuous practice and exploration, the applicant found that the machine also has shortcomings: first, the thermal efficiency is low, and the heat is directly discharged to the atmosphere, thereby causing thermal energy loss and reducing thermal efficiency

The second is to install a leaf pusher in the hopper to push the tea into the drum forcibly, which will easily break the tea and the quality of the tea cannot be effectively guaranteed.

The third is that the greening time of tea leaves in the drum cannot be effectively controlled according to the tea making process, which affects the greening effect
