In the preparation process of the alkyl glycoside, the alkyl glycoside is prepared by mixing glucose and fatty alcohol, gelling, dehydrating and catalyzing. Alkyl glycoside is generally dark in color and needs to be decolorized and bleached, and because of high viscosity and poor flowability of the high-concentration alkyl glycoside, a certain stirring speed is needed in a general bleaching device, however, a lot of foam is easily generated at an excessive speed, so that the decolorizing efficiency is reduced, and therefore, an antifoaming device is needed for auxiliary production.
The most widely used defoaming method is a thermal defoaming method at present, but in the existing thermal defoaming method, serious scaling in a heater is easy to cause, so that the defoaming efficiency is greatly reduced, the energy consumption is increased, the decoloring efficiency is further influenced, and the preparation efficiency of alkyl glycoside is reduced.
