Description
Technical field
The invention belongs to technical field of modified starch, relate to continuous production method of dual-modified starch through dry process.
Background technology
The production method of modified starch can be divided into wet method, solvent method, dry method etc.The Wet Method Reaction mild condition, safe, reaction good uniformity, product purity is high, is the production method that China modified starch manufacturer generally adopts.But also there are many drawbacks in wet production, as: long reaction time, reaction conversion ratio is low, production cost is high, water loss is large, the waste water saltiness is high, very easily causes environmental pollution.Dry technology for production is simple, the reaction times is short, transformation efficiency is high, yield is high, energy consumption is low, production cost is low, it is little to pollute, and meets green modified starch developing direction, is a kind of rising production method.But at present the present situation of China's Dry process Starch Production is: intermittently produce, kind is single, small scale, the quality product fluctuation is large, the product promotion application surface is narrow.And solvent method is high due to production cost, poor stability, harsher to equipment requirements, is difficult to scale operation.
As execute the Jianping, TGBD type modified starch dry process reaction production line and production technique, " chemical science and technology market " 2004 the 8th phases.Introducing this production-line technique flow process is: and ative starch → breaing up, broken arch → interpolation reaction solvent, mixing → drying and dehydrating → reaction → wind be cooling → and secondary adds the single solvent dry production of solvent, mixing → pulverizing → screening → finished product.The document is pointed out: processing requirement: output: 500kg/h; Temperature of reaction: 105～120 ℃; Reaction times: 2～3h; Whiteness, pH value, viscosity meet product standard.Modified starch controlling of production process: because of material characteristic and the user difference to product requirement, need regulate the equipment operating parameter in production line, to obtain customer satisfaction system product.Note following condition: (1) regulates pneumatic dryer vapor pressure and induced draft fan aperture, controls water ratio and material recovery rate that material advances reactor; (2) regulate belt reactor vapor pressure and induced draft fan aperture, control material reaction temperature and the finished product water ratio; (3) regulate the cloth bucket flashboard, control bed thickness in reactor; (4) regulate feeder and reactor main transmission speed, can control output and reaction times; (5) regulate volume pump, the reagent flow that enters high-speed mixer is controlled; (6) regulate quenching system induced draft fan aperture, control product recovery rate.
