Description

TECHNICAL FIELD

[0001] The utility model relates to the field of stevioside production technology, and specifically relates to a system for stevioside production. BACKGROUND

[0002] Stevioside is a natural sweetener extracted from the leaves of stevia rebaudiana, which belongs to glycosides. The sweetness of stevioside is very high, usually 200-300 times that of sucrose, but the heat is extremely low and can be ignored, so it is an ideal sucrose substitute and is widely used in the food industry, pharmaceutical industry, daily chemical products and pet food fields.

[0003] In the production process of stevioside, especially in the extraction process of stevioside, a reaction kettle is needed for processing. When the reaction kettle is used to extract stevioside, it needs to be added and heated. The current adding process uses a direct current pump to pump the raw liquid into the reaction kettle. However, the reaction kettle is integrally formed and opaque, so the amount of raw liquid entering the reaction kettle cannot be known. During the heating process, the raw liquid produces steam when heated. The accumulation of steam in the reaction kettle will increase the pressure in the reaction kettle. If the pressure cannot be discharged in time, it will cause damage to the reaction kettle. In summary, the current reaction kettle used for stevioside production cannot control the adding, temperature control and pressure control uniformly, which increases the difficulty of using the reaction kettle and reduces the production efficiency of stevioside.
