Description

Technical Field

[0001] This invention relates to the field of stevia purification technology, and in particular to a bio-enzymatic assisted purification device for stevia. Background Technology

[0002] In processing stevia, the stevia raw material needs to be cleaned, crushed, and soaked first. Then, specific enzymes are added, and the stevia is enzymatically hydrolyzed under suitable temperature and pH conditions to break down the cell wall structure and release stevia. The stevia in the hydrolysate is then separated from other impurities using techniques such as centrifugation, filtration, or membrane separation. The separated hydrolysate is then passed into a purification tank, where the stevia is further purified using adsorption, desorption, and ion exchange techniques to improve its purity and quality. Finally, the purified stevia is dried.

[0003] However, existing purification tanks require aligning the upper connecting tube with the lower tank body before assembly, and then holding the connecting tube in place before proceeding with the assembly. This is inconvenient, and the connecting tube is prone to displacement due to operational errors during assembly, requiring readjustment and taking a considerable amount of time, thus affecting the assembly efficiency of the purification tank. Summary of the Invention

[0004] In view of this, the present invention provides a stevia bio-enzymatic auxiliary purification device, which can effectively reduce leakage of the enzymatic hydrolysate, ensure the effectiveness of the auxiliary purification tank, and promptly alert the staff to repair when leakage occurs at the connection port of the auxiliary purification tank, avoiding excessive leakage of the enzymatic hydrolysate and waste.
