Abstract

The invention discloses a dry-method double-modified starch continuous production device which is characterized by comprising a liquor tank, an atomization device, a mixer, a powder storage tank, a speed regulating and metering powder feeder, a reactor, a heater, a screw conveyer, a continuous mixer, a lifter, a classifier, an induced draught fan, a powder collection tank, a vibrating screen, a weighing scale and a packaging machine. Continuous feeding, discharging and reacting are realized; the reaction uniformity is high; starch reaction time is controlled by regulating powder feeding speedof the speed regulating and metering powder feeder; reaction temperature is controlled by regulating flow rates of hot air and steam; and the device meets the requirements of large-scale continuous production of dry-method double-modified or single-modified starch, such as cationized-phosphoric esterified starch, acidified-cationized starch, acidified-phosphoric esterified starch, dextrin, cationic starch, phosphate starch and the like. The production device has the advantages of less investment, high reaction conversion rate, high product yield, low production cost, high adjustability of production capacity, stable product quality and obvious ecological environment friendliness and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a continuous production device for dry double-modified starch. Background technique [0002] The production methods of modified starch can be divided into wet method, solvent method, dry method and so on. The wet method has mild reaction conditions, high safety, good reaction uniformity, and high product purity. It is a production method commonly used by my country's modified starch manufacturers. However, there are also many disadvantages in wet production, such as: long reaction time, low reaction conversion rate, high production cost, large water consumption, high salt content in wastewater, and easy to cause environmental pollution. Dry production process is simple, short reaction time, high conversion rate, high yield, low energy consumption, low production cost, less pollution, in line with the development direction of green modified starch, is a promising production metho...
