Abstract
The invention relates to tea leaf dryers, and specifically relates to a tea leaf high-voltage electrostatic field dryer. Drying technology brings direct influence for output and quality of tea leaf, present drying technology usually employs flat type, tunnel type or hot-air circulating type dryers for drying, and the flat type, tunnel type or hot-air circulating type dryers respectively have problems of influencing quality, appearance and output of tea leaf. The high-voltage electrostatic field dryer comprise a baking oven, an evaporating chamber, an air inlet, an air outlet, an air exhaust device and a high-voltage electrostatic field generating assembly; and the high-voltage electrostatic field generating assembly mainly consists of a power supply, a pressure regulating rectifier, an upper pole plate, a lower pole plate and a controller. The tea leaf drying process is performed at a normal temperature when the high-voltage electrostatic field dryer is employed, so that the compositions of tea leaf are effectively protected, and dried tea leaf is small in color and shape variation; the broken rate of tea leaf is low, the quality and the beauty of tea leaf are effectively guaranteed, the output is improved, and especially quality guarantee is provided for production of high-grade tea leaf.
Description
Technical field
The present invention relates to a kind of tea drier, particularly relate to a kind of tealeaves high-voltage electrostatic field dryer.
Background technology
In tealeaves production process, oven dry is a procedure that must carry out, and drying technology will bring direct impact to the yield and quality of tealeaves.At present drying technology adopts flat, tunnel type or heated air circulation type dryer to dry conventionally, there is following problem in these drying mode: the one, and that tealeaves is heated is inhomogeneous, the thermal efficiency is low, drying time is long, easily cause tealeaves chlorophyll destroyed, make tealeaves jaundice; The 2nd, due to above-mentioned oven dry be all under the environment of a higher temperature by the water evaporates in tealeaves out, easily cause the shape of tealeaves to change; The 3rd, in above-mentioned drying course, also must manually ceaselessly stir tealeaves in order to allow steam discharge, thereby cause tealeaves percentage of damage higher.The quality of tealeaves, attractive in appearance and output are directly destroyed or affected to the problems referred to above.
Summary of the invention
For addressing the above problem, improve tea yield, ensure product quality, the invention provides a kind of high-voltage electrostatic field dryer.
High-voltage electrostatic field of the present invention dryer, the energy difference that adopts electric charge to produce due to electromotive force difference in high-voltage electrostatic field, makes the principle that in material, moisture evaporation rate is accelerated solve above-mentioned technical problem, and its technical scheme adopting is as follows:
A kind of tealeaves of the present invention high-voltage electrostatic field dryer, comprises baking oven, vaporization chamber, air inlet, air outlet, air exhausting device and high-voltage electrostatic field generating assembly; Wherein: high-voltage electrostatic field generating assembly is mainly made up of power supply, variable voltage rectifier, top crown, bottom crown, controller; Power supply is civil power, and variable voltage rectifier is connected with power supply, and top crown is installed on vaporization chamber top, and bottom crown is installed on vaporization chamber bottom, and top crown is connected with the negative pole of variable voltage rectifier output, and bottom crown is connected with the positive pole of variable voltage rectifier output.
Described variable voltage rectifier output voltage 10kV.
Described top crown is that pin electrode is fixed at a certain distance on copper sheet material and is formed, the spacing 4cm of each pin electrode.
Top electrode adopts in the situation of single-needle electrodes, under electric field evaporation of water speed with become conic section relation taking the radius as the center of circle under needle point.Top electrode adopts in the situation of multiple pin electrodes, and evaporation of water speed adopts in single-needle electrodes situation fast than top electrode, but is not along with the multiple of pin electrode increases and growth at double.The in the situation that of multiple pin electrode, in the time that the distance between pin electrode becomes large, under electric field, evaporation of water speed also becomes large.
Described bottom crown is the reticular lamina of being made up of aluminum material.It is the circulation of air ensureing in vaporization chamber that bottom crown adopts reticular lamina design, is convenient to aqueous vapor and discharges.
Distance between pin electrode free end and bottom crown on top crown is between 12-16cm.
The invention has the beneficial effects as follows, because tea-drying process is to carry out under normal temperature, effectively protected the composition of tealeaves, and dry after tealeaves color, change of shape little; Tealeaves percentage of damage is low, effectively ensures the quality, attractive in appearance of tealeaves, has improved output, provides quality assurance in particular for producing high-grade tealeaves.
