Description
Technical Field
The utility model relates to the technical field of chemical equipment, in particular to a low-bath-ratio high-substitution hydroxypropyl starch ether production device.
Background
Hydroxypropyl starch ether is one of modified starches, and is etherified starch obtained by carrying out etherification reaction on starch and propylene oxide to replace hydroxyl in a starch macromolecular structure. The hydroxypropyl starch can be widely applied to the fields of food, medicine, building materials, petroleum drilling, textile and the like. Two production processes are mostly adopted for producing domestic hydroxypropyl starch ether. The first method is dry method: putting water, a catalyst and starch into a reaction kettle in proportion, soaking for a certain time at normal temperature, centrifuging, drying, putting the dried starch into the reaction kettle again, heating to the reaction temperature, adding an etherifying agent, and keeping the temperature for a certain time to generate hydroxypropyl starch ether, wherein the hydroxypropyl content of the product produced by the process is low; secondly, a solvent method: putting a solvent, a catalyst and starch into a reaction kettle in proportion, stirring into uniform starch slurry, sealing the reaction kettle, adjusting the temperature to the reaction temperature, adding an etherifying agent, keeping the temperature for a certain time, cooling, neutralizing, centrifuging, drying and crushing to obtain the hydroxypropyl starch ether. The production process has the advantages of high solvent consumption and high product cost, and in addition, the temperature needs to be changed for several times and the heat preservation needs to be carried out for a long time in the production process of the hydroxypropyl starch ether, so that the prior art has no particularly good implementation scheme for the production process.
