Problems solved by technology

At present, the drying technology usually uses flat plate, tunnel or hot air circulation dryers for drying. These drying methods have the following problems: First, the tea is not heated evenly, the thermal efficiency is low, and the drying time is long, which is easy to cause chlorophyll in the tea. The tea leaves are destroyed and the tea leaves turn yellow; the second is that the above-mentioned drying is to evaporate

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 [0001] The invention relates to a tea drying machine, in particular to a high-voltage electrostatic field drying machine for tea. Background technique [0002] In the tea making process, drying is a necessary process, and drying technology will have a direct impact on the yield and quality of tea. At present, the drying technology usually uses flat plate, tunnel or hot air circulation dryers for drying. These drying methods have the following problems: First, the tea is not heated evenly, the thermal efficiency is low, and the drying time is long, which is easy to cause chlorophyll in the tea. The tea leaves are destroyed and the tea leaves turn yellow; the second is that the above-mentioned drying is to evaporate the water in the tea leaves in a higher temperature environment, which will easily cause the shape of the tea leaves to change; the third is that in the above-mentioned drying process, in order to make the Water vapor discharge also must artificial...
