Drum drying is a method used for drying out liquids from raw materials with a drying drum. In the drum-drying process, pureed raw ingredients are dried at relatively low temperatures over rotating, high-capacity drums that produce sheets of drum-dried product. This product is milled to a finished flake or powder form. Modern drum drying techniques results in dried ingredients which reconstitute immediately and retain much of their original flavor, color and nutritional value.

The preparation method comprises the following steps: (1) blending a starch slurry: uniformly stirring water, an expansion inhibitor and native starch to obtain the starch slurry; (2) performing an etherification reaction: adding an etherifying agent to carry out the etherification reaction; (3) performing a crosslinking reaction: adding a crosslinking agent, and carrying out the reaction to reach a desired viscosity; (4) adjusting the pH value of a reaction solution obtained after the crosslinking reaction in step (3)with an inorganic acid solution, adding an esterification agent, carrying out a reaction for 3 h, and then terminating the reaction to obtain the composite modified starch; ad (5) washing and dehydrating the composite modified starch prepared in step (4), and carrying out drum drying to obtain the product. The composite modified starch of the invention is obtained by etherification, the crosslinking reaction and the esterification reaction of the native starch, and the single product can meet the application requirements without being combined with other starches. The preparation method of thecomposite modified starch of the invention has the advantages of easily controlled process conditions, easiness in realization of large-scale industrial production, easiness in operation, and strongpracticability.

Production process for bamboo charcoal polyester staple fibre
InactiveCN102517686ARealize resource reuseReduce manufacturing costFilament forming substance formingArtificial filament heat treatmentPolyesterPolyethylene terephthalate glycol
The invention discloses a production process for a bamboo charcoal polyester staple fibre. In the production process, regenerative PET (Polyethylene Terephthalate) material is used as the material, and the finished product is acquired by pre-treating, rotary drum drying, melt spinning, cooling and forming, winding, drafting, curling, oil applying, thermosetting and cutting-off in sequence, wherein the rotary drum drying comprises the steps of firstly drying the regenerative PET material for 5.5h-6.5h and then adding bamboo charcoal master batches with the final mass fraction of 6%-8% and including bamboo charcoal with the mass fraction of 22%-27%; and the total drying time is 9.5h-10.5h; both the screw rod and the spinning beam of a screw extruder in the melt spinning step are at the temperature from 278 DEG C to 282 DEG C; cooling forming is realized through circular air blow, the temperature of the circular air is 22 DEG C to 26 DEG C, and the air velocity of the circular air is 4.0m / s-5.0m / s; the total draft multiple is 3.1-3.3 times; and the thermosetting temperature is 162 DEG C to 168 DEG C, and the thermosetting time is 13 minutes to 17 minutes. The production process can save the cost and is helpful for environmental protection; the produced product has a better smooth and comfortable hand feeling and moisture-absorption air permeability than those of a normal polyester staple fibre.
