Description
Technical field
The present invention relates to a kind of preparation technology of mono-glycerides, particularly a kind of production method of mono-glycerides particulate.
Background technology
Mono-glycerides, the sour glycerine ester of formal name used at school list 18 (alkane), its Industrial products are micro-yellow wax print shape conventionally, and in the fields such as food-processing, makeup, mono-glycerides Chang Zuowei emulsifying agent, thickening material, stablizer etc. are used.In addition, mono-glycerides also can be widely used in plastics industry, can be used as static inhibitor, dust-proofing agent, inside and outside lubricant agent, releasing agent use, significantly improves the performance of plastic prod.
At present, the production method of mono-glycerides adopts conventionally with lipid acid or stearic acid and direct synthetic the obtaining of glycerine both at home and abroad, and many improvement have been made on this basis, but the mono-glycerides of producing is mainly with spherical, semisphere, sheet is main, particle is larger, mobility, homogeneity, solvability are all poor, cannot adapt to industrial demand.Particularly, in plastics industry field, mono-glycerides Chang Zuowei lubricant is used, and higher to the mobility of mono-glycerides particle and oilness requirement, mono-glycerides prepared by existing production technique cannot meet more.
For the problems referred to above, some enterprises of recent domestic and research and development institution attempt preparing mono-glycerides particulate, so that it is applicable to high-end plastic industry, but result is all undesirable, and complex process, and cost is higher.In addition, existing mono-glycerides color and luster turns to be yellow and is deep, can affect the color and luster of product itself while using as foodstuff additive or as other additives.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the invention provides a kind of production method of mono-glycerides particulate, little, the light good luster of mono-glycerides diameter of particle of producing by the method, cost is low, technique is succinctly efficient.
The production method of a kind of mono-glycerides particulate provided by the invention, carry out as follows successively:
(1) hydrogenated palm kernel oil and glycerine mixing are carried out to mono-glycerides building-up reactions;
(2) then add alkaline matter to regulate acidity;
(3) add again the atlapulgite processing of decolouring;
(4) the mono-glycerides liquid through decolouring is transported in sponging granulator, by the spray gun in sponging granulator by mono-glycerides liquid with vaporific ejection, the vaporific mono-glycerides liquid of ejection is carried out to wind cooling simultaneously, obtain mono-glycerides particulate after cooling.
The particle diameter of the mono-glycerides particulate making is as stated above 0.8-1 micron.
The temperature of reaction of the synthetic mono-glycerides of described hydrogenated palm kernel oil and glycerine is controlled at 50-60 ℃.
The cooling temperature of described wind is 10-15 ℃.
The mass ratio of described hydrogenated palm kernel oil, glycerine, atlapulgite is: hydrogenated palm kernel oil: glycerine: carclazyte=80-90:9.5-18:0.5-2.
Adjusting acidity in described step (2) is that pH value is controlled between 2～3.
The alkaline matter that above-mentioned adjusting acidity is used is caustic soda or soda ash.
The production method of a kind of mono-glycerides particulate provided by the invention, has following beneficial effect:
(1) production process only needs 4 steps, rapidly and efficiently, is convenient to the scale operation of mono-glycerides particulate;
(2) under the condition of building-up reactions, pH regulator, decolouring, mono-glycerides liquid is carried out to spray cooling, obtain particle diameter at the Tegin 55G particulate of 08-1.0 micron, make it have good mobility and oilness, the lubricant that can be used as especially high-end plastics industry is used.
(3) adopt atlapulgite to decolour, make Tegin 55G particulate there is oyster white gloss, overcome the disadvantageous effect that existing mono-glycerides brings because of jaundice obfuscation.
