The processing of green tea is simply divided into three steps: fixation, shape and drying. Among them, fixation is a decisive role in the quality of green tea. The factors that affect the quality of the greening include the temperature of the fixation, the amount of leaves thrown, the type of the greening machine, the time of fixation, and the method of the fixation.
At present, the commonly used fixation equipment in production include pot-type machine, bay simple type, mesh belt or moving bed type steam fixation machine, microwave (light wave) fixation machine. The use of microwave fixation machine, mainly using microwave heating fast, short time, the moisture in the tea leaves quickly vaporizes, to passivate the active oxidase in the fresh leaves, prevent the serious color change in the subsequent drying process, and volatilize the smell of ayurveda in the fresh leaves. Reduce the bitterness and astringency of tea, increase the degree of harmony of tea, so that the color and fragrance of tea can be retained to the greatest extent in the process of greening.
The microwave tea fixation machine overcomes the influence the shape and color of tea leaves referring the drum fixing machine, achieve the effect of no scorch edge and explosion point. The steam fixation machine has a high water content in the steam, and the out layer of the raw material is affected by high temperature. The resulting are not conducive to dehydration, part of the chlorophyll is destroyed, the nutrients contained in the raw materials are partially lost with the condensed water, and the color and luster are greatly affected. The microwave tea fixation machine is faster and more efficient than traditional equipment such as pot type and drum type. High quality, good color, and good degree of publicity are more energy-saving and environmentally friendly. The microwave tea greening machine will be widely used.
Application: used for tea greening, drying, alcoholization, enzyme killing, sterilization and insect killing， suit on various tea leaves. Like bay leaves, herbs, moringa leaves,puer and so on.
Advantages of the equipment: The equipment is easy to operate, stable and reliable in performance, efficient and energy-saving, high-quality material selection and careful design and manufacture ensure that microwave leakage meets national standards; the conveyor belt meets food hygiene standards, not pollute tea, it is safe and hygienic; continuous producing.
The advantages of microwave tea making: microwave tea heating is rapid and uniform, so that the aroma is revealed, the grass gas is volatilized, and the flavor is enhanced; the color of the tea leaves is pure; , especially suitable for processing high-grade tea, at the same time sterilization, insecticide, mildew prevention, and prolong shelf life.
