Method for producing crystalline fructose from sucrose

Номер: CN104673942A
Автор: DENG HECHAO, XU WEIXIONG
Принадлежит:

The invention provides a method for producing crystalline fructose from sucrose. The method sequentially comprises the following five main steps: sucrose hydrolysis, decoloration and hybridization, chromatographic separation, evaporative concentration and crystal drying. According to the method, sucrose is processed into crystalline fructose with the sugar content above 99%; by reasonably setting procedure parameters including heating and pressurizing in a sucrose dehydration process, setting a simulated moving bed in a chromatographic separation process and selecting crystal seeds in a crystallization process, the problems of high production cost and energy consumption and low production efficiency caused by defects of an existing production process are overcome; industrial mass production proves that the purity of a crystalline fructose product reaches above 99%, the average output rate of crystalline fructose prepared from the sucrose is above 42%, and a secondary product, namely high ...

The invention discloses a fiber-gluing compound centering process. The process sequentially comprises a feeding procedure, an atomization-fiber gluing procedure, a centering-compounding procedure and a winding procedure, wherein a flange splitting procedure can be added between the centering-compounding procedure and the winding procedure. The process is characterized in that glue materials are subjected to data integration by an encoder, enter a spray gun through a glue pipe according to the injection amount of a gear pump, are uniformly sprayed to a membrane material through a gun hole structure, and are centered and compounded with a non-woven fabric so as to obtain a product. According to the process, the materials can be saved, and the cost can be lowered; furthermore, the sprayed glue materials are rapidly cooled, are unlikely to permeate and can be compounded to the ultrathin non-woven fabric, so that the product has good flexibility and a high comfortable degree.
