Description
Technical Field
The utility model relates to a tea processing equipment technical field, concretely relates to black tea rolling device.
Background
Black tea belongs to the category of fully fermented tea, and is refined by taking the buds and leaves of tea trees as raw materials through typical processes of withering, rolling, fermentation, drying and the like, wherein the rolling is a primary shaping process of black tea, a bent appearance is formed by the rolling, and the improvement of the internal quality is also influenced. In the rolling process, rolled tea leaves are subjected to two effects of flat pressure and curved pressure in a rolling barrel to enable a tea ball to roll, leaves in the tea ball are subjected to extrusion force to generate wrinkles, the wrinkles of the leaves are basically parallel to main veins and are close to the main veins to be curled into strips due to the fact that the main veins are high in hardness, partial leaf cells are twisted and broken when the rolled leaves pass through a maximum pressure area of rolling quantity in turn, extruded tea juice is attached to the surface, the cohesiveness of the leaves is increased, and water-soluble substances form tea soup concentration.
In the field of black tea production and processing, the rolling procedure is mostly finished manually, under the normal condition, a rolling barrel is placed on a hot air port, and the deformation of the rolled leaves is accelerated by means of heat provided by hot air exhausted from the hot air port. In the prior art, the hot air discharged from the hot air outlet is constant, namely the heat quantity provided by the hot air outlet is constant, and the required heat quantity of the hot air outlet needs to be adjusted immediately by observing the change of the rolling leaves as the rolling is continuously carried out, otherwise, the final state of the rolling leaves does not reach the ideal state, thereby affecting the quality of the black tea.
For this reason, chinese patent publication No. CN203467588U discloses a black tea rolling mechanism, which utilizes the rotation of the air outlet to install a baffle, the end of the bending rod is fixedly connected to the rotation shaft of the baffle, the bending rod is utilized to drive the baffle to rotate to adjust the air output, but only the inclination of the baffle in the air outlet can be adjusted, so that the baffle can block the middle of the air outlet, only the gap between the baffle and the wall of the air outlet can be used for outputting hot air, and the center of the air outlet cannot be used for outputting hot air, thus, the problem of uneven heating when rolling black tea is caused.
SUMMERY OF THE UTILITY MODEL
The utility model provides a black tea rolling device to be heated inhomogeneous problem when solving among the prior art black tea rolling.
In order to achieve the above object, the present invention provides the following technical solutions: the utility model provides a black tea rolling device, is including rolling a section of thick bamboo and hot-blast way, it is provided with the layer board to roll a section of thick bamboo internal fixation, the layer board equipartition has a plurality of holes of airing exhaust, the bottom coaxial rotation of rolling a section of thick bamboo is connected with the sleeve, telescopic one side coaxial rotation of keeping away from to roll a section of thick bamboo is connected with the ventilation pipe, ventilation pipe and hot-blast way intercommunication, the mouth of pipe of ventilation pipe is provided with the closing plate, the closing plate is provided with a plurality of first exhaust vents at even interval on the circumferencial direction, be provided with the regulating plate with closing plate top butt in the sleeve, the regulating plate is provided with the second.
The utility model discloses a theory of operation: drive the regulating plate through rotating the sleeve and rotate, because regulating plate and closing plate butt, and be located the second exhaust vent on the regulating plate and the first exhaust vent one-to-one on the closing plate, consequently, rotation through the regulating plate, make first exhaust vent and the crisscross stagger of second exhaust vent, make the regulating plate part shelter from first exhaust vent, reach the purpose of adjusting the amount of wind, because first exhaust vent and second exhaust vent all are provided with the multiturn from inside to outside, consequently when adjusting the amount of wind, hot-blast still can blow off through first exhaust vent and second exhaust vent, hot-blast hole discharge is also even to the heating of tealeaves through airing exhaust.
The utility model has the advantages that: because a plurality of first exhaust vents evenly spaced setting on the circumferencial direction of closing plate, when consequently adjusting the amount of wind, the regulating plate part shelters from first exhaust vent, and hot-blast all can blow out behind first exhaust vent and the second exhaust vent, and tealeaves is kneaded and is heated more evenly.
Furthermore, the outer wall of the sleeve is coaxially and fixedly sleeved with a gear, and the gear is meshed with a rotating handle. Because the temperature of the sleeve is raised due to hot air, the gear is driven to rotate by rotating the rotating handle, and then the gear drives the sleeve to rotate to realize the adjustment of the air quantity.
Further, the twisting cylinder is connected with a support frame. In order to prevent the twisting cylinder from being affected when the sleeve is adjusted, a support frame is provided to support the twisting cylinder.
Further, the outer diameters of the twisting cylinder and the ventilation pipe are the same. When hot air is exhausted through the exhaust hole at the bottom of the rolling barrel, the bottom of the whole rolling barrel is provided with the hot air because the outer diameters of the rolling barrel and the ventilation pipe are the same, and the tea leaves are heated more fully.
Furthermore, a filter screen is arranged in the air exhaust hole. In order to prevent the scraps of the tea from falling into the ventilation pipe through the air exhaust hole when the tea is kneaded, the filter screen is arranged to block the scraps of the tea.
Further, the supporting plate is in threaded connection with the inner wall of the twisting barrel. Through rotating the layer board, take out the layer board from rolling in the section of thick bamboo, do benefit to and wash the airing to the layer board.
