Auto discharging system for preparing light-coloured transparent alkyl glycoside

Abstract

The invention discloses an automatic discharging system which is used to prepare light-colored transparent alkyl glucoside and comprises a plate evaporator for evaporating the alkyl glucoside mixture, a discharging pump for outputting high-viscosity alkyl glucoside, a direction control valve for controlling the output of the high-viscosity alkyl glucoside, and a color drifting kettle for drifting the color of the high-viscosity alkyl glucoside. The technical proposal of the invention is that the invention has a discharging pump which can timely and directly outputs the high-viscosity alkyl glucoside inputted by the plate evaporator through the direction control valve to the color drifting kettle for color drifting so as to ensure continuous and automatic production to improve the production efficiency and save manpower and resources; besides, the discharging pump runs at all times so as to avoid the color deepening caused by local high temperature due to the large accumulation of alkyl glucoside; moreover, the discharging system is a closed system, so that the external air can not easily enter the system to avoid the alkyl glucoside color deepening as a result of air oxidation.

Description

technical field [0001] The invention relates to the field of preparation and processing of sugar derivatives, and more specifically relates to an automatic discharge system for preparing light-colored transparent alkyl glycosides. Background technique [0002] The current advanced technology for the production of alkyl glycosides is the "direct method" technology, which is to make medium and long chain C8-18 fatty alcohols and glucose directly carry out solid / liquid reaction under certain temperature, vacuum (pressure) and acid catalyst. Alkyl glycosides are prepared by the corresponding reaction, and the reaction principle is the acetalization process of the hemiacetal hydroxyl group on the glucose ring and the fatty alcohol hydroxyl group. In the preparation process of alkyl glucoside, in order to obtain the suitable alkyl glycoside product of sugar polymerization degree, fatty alcohol is often used in excess, so that the alkyl glycoside prepared after the reaction finishe...

Problems solved by technology

[0009] Aiming at the defects that the existing light-colored alkyl glycoside discharge system has the disadvantages that the production is easily interrupted and the color of the alkyl glycoside is easily further deepened, the purpose of the present invention is to provide an automatic discharge system for preparing light-colored transparent alkyl glycosides. system, the equipment can ensure the continuity of production, and can realize that the color of alkyl glycosides in production will not be further deepened
