    • The invention relates to a process for preparing a randomly-bonded polysaccharide, comprising as ingredients a saccharide, a polyol and an acid serving as a catalyst, the process comprising the steps of feeding the ingredients into a reactor in order to dehydrate the fed ingredients to an essentially anhydrous syrup, polycondensating the essentially anhydrous syrup at elevated temperatures in the said reactor while removing the reaction water, wherein the reactor is a mixing kneader device with counter-acting blades, wherein during the feeding step the saccharide, the polyol and the acid serving as catalyst are simultaneously or consecutively fed to the reactor, and in that during the dehydratation and polycondensation step the free water and reaction water is removed from the mixing kneader device by kneading and mixing the fed ingredients and the subsequent essentially anhydrous syrup under reduced pressure in the reactor, and during the polycondensation the essentially anhydrous syrup is continuously kneaded in the kneader reactor until the required degree of polymerisation is obtained.
    • 本发明涉及一种制备随机结合的多糖的方法,其包括作为成分的糖,多元醇和用作催化剂的酸,该方法包括以下步骤:将成分进料到反应器中以将进料成分脱水至 基本上无水的糖浆,在升高的温度下在所述反应器中将基本上无水的糖浆缩聚,同时除去反应水,其中反应器是具有反作用叶片的混合捏合机装置,其中在进料步骤期间,糖,多元醇和酸 作为催化剂同时或连续地供给到反应器中,并且在脱水缩聚步骤中,通过在进料成分和随后的基本上无水的糖浆中减压混合混合,从混合捏合机中除去游离水和反应水 在反应器中,在缩聚过程中,基本上是无水的syr 在捏合机反应器中连续捏合,直到获得所需的聚合度。
