Description

Tea-drying method

Technical field

The present invention relates to tea machinery manufacturing technology field, especially a kind of method for the tea-drying after fermenting.

Background technology

Existing is all generally adopt tea-drying equipment to complete for the fresh tea leaf in its dry method that completes, and tea-drying equipment generally comprises hot gas input pipe and is linked in a cylindrical shell, and cylindrical shell is square or circular, and hot-wind inlet is located at cylindrical shell top.Cylindrical shell put into by tealeaves, hot gas enters cylindrical shell from hot-wind inlet and carries out drying to tealeaves, but tealeaves is heated uneven in cylindrical shell, the tealeaves overdrying on upper strata, and the tealeaves of lower floor is also very wet, thus needed certain hour to stir tealeaves, not only troublesome poeration, the uniformity of tea-drying is appointed so very low.Some enterprise is provided with the stirring vane of driven by motor in cylindrical shell, although solve the uneven problem of tea-drying like this, make drying drum structure complicated, and increase the consumption of electric energy, processing cost is high.Thus need a kind of can evenly and effect Canon consumes the needs that low drying means meets market.

Summary of the invention

Problem to be solved by this invention is to provide a kind of tea-drying method, to solve existing tea-drying method uneven drying, the problem that drying effect is not good.

In order to solve the problem, technical scheme of the present invention is: this tea-drying method comprises a kind of tea-leaf withering machine of use and carries out drying to tealeaves, described tea-leaf withering machine includes the cylindrical shell that top has hot-wind inlet, described cylindrical shell side has the opening for putting tealeaves, lid is hinged with outside opening, one hot gas input pipe accesses described cylindrical shell by described hot-wind inlet, at least two bending downward heating pipes are extended from described hot-wind inlet, described heating pipe end gas outlet is outwards dispersed in horn-like, described heating pipe end gas outlet is towards the barrel of described cylindrical shell, the lowest part of described heating pipe is the lowest part of described gas outlet, at least two described heating pipes are evenly distributed in described cylindrical shell, described cylindrical shell has at least two and is symmetrically set on a platform, has leg under described platform, the bottom angled of described cylindrical shell, the sidewall of described cylinder body bottom lowest part has tea outlet, and described tea outlet is also provided with lid outward,

Its drying steps comprises: put into from the opening of tea-leaf withering machine by the tealeaves after fermentation, put into that tea amount is cylindrical shell volume 1/1 to five/4th, open hot gas input pipe input hot gas, tealeaves is overturn in cylindrical shell dance in the air, from tea outlet tea delivery after temperature in cylindrical shell reaches 5 minutes ~ 8 minutes of 80 ° of C, the tealeaves constantly gone out from tea outlet puts into cylindrical shell from opening again, so continues after 3 minutes ~ 5 minutes, the tealeaves gone out from tea outlet gathers, and no longer puts into cylindrical shell inner drying; Again put into next group tealeaves and carry out drying.

Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:

The special drying machine of this tea-drying method carries out drying to tealeaves, by least two heating pipes of particular design, the hot gas of hot-wind inlet is blowed to barrel at cylindrical shell, and produce outside blowing force by horn mouth, hot gas is rotated in cylindrical shell, tealeaves is overturn in cylindrical shell, is heated evenly; Horn mouth produces outside blowing force makes the interior wind close to barrel surrounding of cylindrical shell to barrel corner, makes not leave heating and the mixed dynamic dead angle of tealeaves in cylindrical shell.This tea-drying method is dispersed due to tealeaves, thus without the need to too high baking temperature and drying time, saves the energy; Twice dry, and effect is very good, and namely water content arrives 5%; Without the need to using other electric energy, just can realize the automatic stirring of tealeaves in cylindrical shell, both solved tealeaves and to be heated uneven problem, in turn save heating energy source, easy to use, homogeneous heating, heating cost is low.

Detailed description of the invention

Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail:

This tea-drying method comprises a kind of tea-leaf withering machine of use and carries out drying to tealeaves, tea-leaf withering machine shown in Fig. 1, Fig. 2 as, include the cylindrical shell 1 that top has hot-wind inlet 2, one hot gas input pipe logical 9 is crossed hot-wind inlet 3 and is accessed cylindrical shell 1, cylindrical shell 1 side has the opening 4 for putting tealeaves, be hinged with lid 6 outside opening 4, lid 6 have lock and button.At least two bending downward heating pipes 3 are extended from hot-wind inlet 2, here four heating pipes 3 are had, divide equally and be distributed in cylindrical shell 1, the hot gas of hot-wind inlet 2 is blowed to barrel at cylindrical shell 1, and produce outside blowing force by heating pipe 3 end gas outlet, hot gas is rotated in cylindrical shell 1, tealeaves is overturn in cylindrical shell 1, is heated evenly.Heating pipe 3 end gas outlet is outwards dispersed in horn-like, heating pipe 3 end gas outlet is towards the barrel of cylindrical shell 1, the lowest part of heating pipe 3 is the lowest part of heating pipe 3 gas outlet, heating pipe 3 horn mouth produces outside blowing force, make the interior wind close to barrel surrounding of cylindrical shell 1 to barrel corner, make in cylindrical shell, not leave heating and the mixed dynamic dead angle of tealeaves.The bottom angled of cylindrical shell 1, bottom cylindrical shell 1 lowest part sidewall on have tea outlet 5, tea outlet 5 is outer is also provided with lid 6, facilitates tea delivery.This tea-drying method, without the need to using other electric energy, just can realize the automatic stirring of tealeaves in cylindrical shell, and both solved tealeaves and to be heated uneven problem, in turn save heating energy source, easy to use, homogeneous heating, heating cost is low.Cylindrical shell 1 has two, and is symmetrically set on a platform 7, and platform has leg 87 times.

Its drying steps comprises: put into from the opening of tea-leaf withering machine by the tealeaves after fermentation, put into that tea amount is cylindrical shell volume 1/1 to five/4th, open hot gas input pipe input hot gas, tealeaves is overturn in cylindrical shell dance in the air, from tea outlet tea delivery after temperature in cylindrical shell reaches 5 minutes ~ 8 minutes of 80 ° of C, the tealeaves constantly gone out from tea outlet puts into cylindrical shell from opening again, so continue after 3 minutes ~ 5 minutes, the tealeaves gone out from tea outlet gathers, no longer put into cylindrical shell inner drying, namely water content arrives 5%; Again put into next group tealeaves and carry out drying.
