The invention discloses an air-drying method and equipment for ingot maple leaves, and relates to the technical field of tea processing. The mature green leaves of ingot maple leaves that are free from diseases and insect pests, mildew and rot, and miscellaneous leaves and branches are picked from August to October, rinsed with water to remove dust, Sediment, after draining the water, put it into an electrochemical device, using carbon nanotubes as anode, copper mesh as cathode, pole plate spacing of 3-4cm, chlorophyll copper sodium salt solution as electrolyte, at voltage 4-5V, Under the condition of current density of 100-200A/cm 2 , the treatment time is 10-20min; then immersed in edible sterilization solution, soaked for 5-10min, taken out and drained; then snap-frozen in liquid nitrogen for 10min at -198℃, and then wake up at room temperature Freeze for 5 hours; put it in an air-drying device to air dry. The invention can form very stable chlorophyll copper in the chlorophyll of Yuanbao maple leaves through electrolysis, can stably maintain the fresh green of the leaves, and can increase the protein, carbohydrate hydrolysis, increase of small molecular substances, and partial aromatic substances in the fresh leaves of Yuanbao maple. , and can continue to effectively inhibit the growth of microorganisms. |
