Problems solved by technology

[0003] The determination of stevioside glycosides generally adopts high-performance liquid chromatography, which has high accuracy. However, the purity of the stevioside extract is high. If there are many impurities in the sugar solution, it is difficult to run a stable baseline during the measurement operation. It is difficult to accurately identify the peaks of each glycoside, which affects the accuracy of the determination and calculation of the content of each glycoside, so the impurities contained in the sugar solution should be removed as much as possible during the extraction of the sugar solution

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] 1. A structure of a stevia sugar liquid extraction device:

[0021] (1) A stevia sugar solution extraction device, which is composed of an "h"-shaped siphon, a liquid storage tank 1, a liquid storage ball chromatography column 14, a control conduit 6, and a liquid outlet conduit 13. It is characterized in that the siphon It is an "h" shaped three-way glass tube with an air bag 8 at the top and an inclined density switch 12 in the middle. The front section has a piston valve 9 and is connected to the liquid outlet 7 of the liquid storage tank, and the rear section is connected to the liquid outlet conduit 13 leading to In the liquid storage ball chromatography column 14, the outlet height of the rear section is lower than the entrance height of the front section; the density switch 12 is a glass tube connecting the front and rear sections of the "h" shaped siphon...

Abstract

The invention discloses a use method of a stevia sugar liquid extraction apparatus. When washing with an acid, an alkali and distilled water is needed in a process of extracting a stevia sugar liquid, the stevia sugar liquid extraction apparatus can be used to automatically supplement a liquid and control a height of a supply liquid level in a washing process. The method can relatively well realize automatic washing with the acid, the alkali and distilled water in the process of extracting the stevia sugar liquid, guarding and liquid supplement are not needed for an operator, time is saved, and work efficiency is improved.

Description

technical field [0001] A method for using a stevia sugar liquid extraction device, relating to the technical field of experimental equipment, more specifically, a method for using a device for automatically adding liquid to perform chromatography column washing during the stevia sugar liquid extraction process, which can effectively control The height of the liquid level in the chromatography column saves the operator's experiment time and improves the operation efficiency. Background technique [0002] The sweetness of steviol glycosides contained in stevia leaves is 250-300 times that of sucrose, but the calories contained are only 1 / 300 of sucrose. It is the sweetest natural sweetener known so far. There are ten main sweet components contained in stevia leaves: steviol glycoside (STV), steviol biglycoside (STB), rebaudioside A, B, C, D, F, M (RA, RB, RC, RD, RF, RM), dulcoside A (DA) and rubusoside (RUB). The taste and sweetness of different steviol glycosides are diffe...
