Description

Technical Field

[0001] The utility model relates to the technical field of rebaudioside B production, in particular to a rebaudioside B production device. Background Art

[0002] Stevia is a new natural sweetener extracted from the herb Stevia rebaudiana (also known as stevia leaf), a member of the Asteraceae family. Stevia has been used in South America for centuries as a medicinal herb and sugar substitute. International sweetener industry data indicates that steviol glycosides are widely used in food, beverages, and seasonings across Asia, North America, South America, and the European Union. China is the world's leading producer of steviol glycosides.

[0003] Among steviol glycosides, rebaudioside A has been widely used as a sweetener in food and beverages. However, its drawback is its naturally bitter or grassy aftertaste, which limits its further use as a sugar substitute. Rebaudioside B is also a sweet component of steviol glycosides. Its structure is similar to rebaudioside A, differing only by a glucose group at C19 of the aglycone. Its sweetness is comparable to rebaudioside A, but without the bitter aftertaste, resulting in a superior taste.

[0004] Currently, rebaudioside B is mainly extracted from stevia leaves, but the content of rebaudioside B in stevia leaves is very low. Obtaining it from nature is not only costly but also the output cannot meet the demand. Summary of the Invention

[0009] As an improved technical solution, the inlet of the anion exchange resin column is connected to a first purified water tank through a pipeline, the outlet of the anion exchange resin column is connected to a water washing liquid tank through a pipeline, and the outlet of the water washing liquid tank is connected to the concentration tank through a pipeline.

[0010] As an improved technical solution, the solid phase outlet of the filter is connected to a washing tank, the inlet of the washing tank is connected to a second purified water tank through a pipeline, and the outlet of the washing tank is connected to the dryer through a pipeline.

[0011] As an improved technical solution, the liquid phase outlet of the filter is connected to the regulating tank through a pipeline.

[0012] As an improved technical solution, the anion exchange resin column is a macroporous or gel-type anion exchange resin column containing hydroxyl groups.

[0013] As an improved technical solution, the outlet of the concentration tank is connected to the insulation tank through a circulation pump, and the outlet of the insulation tank is connected to the regulating tank through a feed pump.

[0014] As a preferred technical solution, the outlet of the concentration tank is connected to the inlet of the concentration tank through the circulation pump.

[0015] As a preferred technical solution, the outlet of the insulation tank is connected to the inlet of the concentration tank through a feed pump.

[0016] Due to the adoption of the above technical solution, the beneficial effects of the utility model are:
