Abstract

본 발명은 고치환도 양성전분의 제조방법에 관한 것으로 전분을 혼합기내에 투입하고 유동층 상태로 계속 혼합시키며 3-클로로-2-하이드록시프로필트리메틸암모늄 클로라이드(3-Chloro-2-hydrowypropylammonium chloride) 또는 에폭시프로필암모늄 클로라이드(Epoxypropy1-ammonium chloride)등의 양성화제를 미세하게 분무하는데, 이때 양성화제의 균일한 분무(噴霧)를 위하여 양성화제 액을 정량 압축펌프를 이용하여 2;1로 가압한 후 노즐을 통과시켜 비산하게 하여 전분가 접촉 면적을 최대한으로 하였다. 그리고 양성화 약품이 전분에 흡착하는 순간에 강력한 전단력을 가하여 덩어리(플록)가 생기는 것을 방지하였고(제2도)에서 보는 바와같이 이를 계속 와류(渦流)시켜 약품의 확산이 전분의 표면에서 내부로 침투되게끔하여 고치환도 양성전분의 제조방법을 제공한다. 본 발명에 의한 양성전분 제조법은 종래의 방법에 비해 반응수율이 높으며 치환도가 높을 뿐만 아니라 제조공정이 간단하여 공업적으로 매우 유용한 방법이다.The present invention relates to a method for producing a high-substituted cationic starch, the starch is added to the mixer and continuously mixed in a fluidized bed, 3-chloro-2-hydroxypropyltrimethylammonium chloride (3-Chloro-2-hydrowypropylammonium chloride) or epoxy Atomizers such as propyl ammonium chloride (Epoxypropy1-ammonium chloride) are finely sprayed. At this time, in order to uniformly spray the amphoterics, the anolyte solution is pressurized to 2: 1 using a quantitative compression pump. It was made to pass through, and the starch contact area was maximized. At the moment when the protonated chemical is adsorbed on the starch, strong shearing force is applied to prevent the formation of lumps (Flock). As shown in Fig. 2, the vortex is continuously vortexed so that the diffusion of the chemical penetrates from the surface of the starch. It provides a method of producing high-substituted cationic starch. Cationic starch production method according to the present invention is a highly useful method industrially because the reaction yield is higher than the conventional method, the degree of substitution is high, and the manufacturing process is simple.
