Abstract
The present invention discloses preparation technology for preparing cation starch by a dry method, which is characterized in that the new preparation technology utilizes the mixed solution of alcohol and water to dissolve sodium hydroxide; the sodium hydroxide can not cause the pasting of starch in the mixed solution of alcohol and water at high concentration, and meanwhile, the reaction is loose after the sodium hydroxide is added into the mixed solution; no starch granules appear, and the water of the reaction phase can enable the water of the reaction phase to reach the optimal requirement required by the reaction by adjusting the proportion of the water and the alcohol. The prepared cation starch has the advantages of high reaction efficiency, low cost, good whiteness and fineness, and low content and good viscosity stability of soluble starch, and can be widely applied to the technical field of starch processing.
Description
Technical field
The present invention relates to food processing technology field, the production technique of definite a kind of dry production cationic starch of saying so
Background technology
The dry production cationic starch has two kinds in the form that adds caustic soda at present:
1, directly adds sheet alkali to the starch the inside
Though this mode is can amyloplastic gelatinization, but because adding is solid alkali, solid alkali can not fully be penetrated into starch molecule inside, thereby starch can not farthest be activated, cause the reaction efficiency of cationic starch lower, the cost of product improves greatly.And solid mixes with solid, want to reach very uniform degree of mixing and be difficult to, thereby reaction is also inhomogeneous, causes unstable product quality.
2, in starch, add the rarer alkali (2% left and right sides concentration) of concentration ratio
Though this mode can make alkali fully be penetrated into the starch molecule the inside and go, but, be easy to amyloplastic gelatinization, and have a lot of small-particles generations, thereby influence the quality of product, and, if it is excessive to add alkali number, can cause the water content of reacting phase quite high, be not suitable for carrying out dry process reaction, must carry out predrying, thereby increased production cost.
Summary of the invention
Purpose of the present invention, it is the deficiency that exists at traditional mode of production cationic starch production technique, and provide a kind of new dry process to produce the cationic starch production technique, with the cationic starch of this explained hereafter reaction efficiency height not only, cost is low, and have good whiteness and fineness, the content of Zulkovsky starch is lower, viscosity and good stability.
For reaching above-mentioned technical purpose, the present invention has taked following technical scheme: a kind of production technique of dry production cationic starch is characterized in that: used starting material are as follows: starch, trichlorine dihydroxypropyl trimethyl ammonium chloride (quaternary amine type etherifying agent), caustic soda, alcohol
Its technology and fill a prescription as follows
The add-on of etherifying agent is decided (reaction efficiency calculates by 85%) according to the substitution value of requirement cationic starch.Etherifying agent and caustic soda mol ratio between the two is: 1: 1.5-2 is made into 1 mole caustic soda wherein the caustic soda solution of 10-15% left and right sides concentration.Pour into then in the etherifying agent its first epoxidation.(alcohol accounts for 50-60% with alcohol and water with the caustic soda of remainder, water accounts for 40-50%) be made into 8% solution, epoxidised etherifying agent and caustic soda solution are added in the starch, the predrying equipment that starts on the dry method starch reactor is dried to about water content≤16-20%, enter the main reactor of new dry process starch reactor, be warming up to the 60-80 degree, reacted 4-6 hour, be cooled to 50 degree, add the hydrochloric acid of over dry amount of starch 10% concentration in reactor, the pH value of adjusting reacting phase is between the 4-6, mixes about half an hour, start the discharging equipment of reactor, the beginning discharging, packing.
Owing to take technique scheme, according to the cationic starch of this explained hereafter reaction efficiency height not only, cost is low, and has good whiteness and fineness, and the content of Zulkovsky starch is lower, and viscosity stability is good.Can be widely used in the interior toughener of slurry and the retention filtration adjuvant of paper industry, the fluid loss agent of petroleum industry has the sewage flocculant of negative charge etc.
Embodiment
The invention will be further described below in conjunction with embodiment
Production formula is as follows:
Over dry starch 500Kg, etherifying agent 29.7kg (69%), caustic soda 26.2kg (30%), alcohol 20kg
Require the quality index of the cationic starch of producing as follows:
Moisture content≤12%, phosphorus content 0.2521%DS=0.03, whiteness 〉=88, fineness 〉=95, viscosity 〉=50-150CP, pH value 5.0-7.0
Should fill a prescription and produce, can obtain the desired cationic starch of above quality index according to the above technology.
