[0002] Stevioside is a new type of sugar source that is extracted and refined from the leaves of the perennial herbaceous plant of the Asteraceae family, Stevia rebaudiana, using high-tech technology. It is a natural, safe, health-care and functional new sugar source. It appears as a white powder or crystal, with a sweetness 200 to 300 times that of sucrose and 1 / 300 of the calories of sucrose. It is widely used in industries such as food, beverages, condiments, pickled products, tobacco, medicine, brewing and daily chemical products. At the same time, it is also the most ideal sugar substitute for patients with diabetes, obesity, cardiovascular and cerebrovascular diseases, hypertension and dental caries, as well as people who advocate nature and pursue health and beauty.

[0003] At present, the equipment for producing stevioside usually adopts the resin exchange method to extract and produce stevioside. The main processes are crushing, extraction, flocculation, filtration, decolorization, adsorption, refining, sterilization filtration, spray drying and metering packaging. In the adsorption resin stage, alcohol is used to analyze (elute) stevioside, and a large amount of low-alcohol analysis liquid is produced during the analysis process.

[0004] For example, Chinese patent CN204307394U discloses an automatic stevioside distillation device, which is easy to operate, has an intelligent control system that improves evaporation efficiency, reduces alcohol loss, and utilizes membrane separation technology to achieve a high purity of recovered alcohol.
