Abstract

The invention discloses a drying method of a propolis ethanol extract. The drying method comprises the step of drying the propolis ethanol extract in a spray drying tower, so as to obtain a propolis ethanol extract with the ethanol content of 0-1%, wherein the inlet air temperature of the spray drying tower is 150-165 DEG C, the outlet air temperature is 95-100 DEG C, the atomization frequency is 250Hz-280Hz, the charging frequency is 4Hz-6.5Hz, and the air induction frequency is 20Hz-40Hz. Compared with traditional drying methods, the drying method has the advantages that the production cycle of the same batch of products is shortened by 4-5 times, and inherent aromatic substances and heat-sensitive active ingredients of propolis are preserved better.

Description

technical field [0001] The invention relates to the technical field of extraction and drying of plant components, in particular to a drying method of propolis ethanol extract. Background technique [0002] Propolis is a viscous gelatinous substance made by honeybees collecting the young shoots or callus of glue source plants and secreting them, and mixing them with secretions of their own glands, pollen and beeswax. Propolis is rich in a variety of biologically active substances, especially flavonoids, which have a variety of health care effects and are known as "purple gold". [0003] Different extraction methods of propolis have different active ingredients. At present, the commonly used extraction methods are: ethanol extraction, water extraction, supercritical extraction, ultrasonic-assisted extraction, enzyme extraction, boron polymer electrolyte method, and microwave-assisted extraction. Wait. Among them, the equipment required for the ethanol extraction method is si...
