Starch Airflow Dryer

Starch Airflow Dryer Project Overview

Starch is a high polymer of glucose, hydrolyzed to the disaccharide stage as maltose, and completely hydrolyzed to get monosaccharide (glucose). There are two types of starch: straight chain starch and branched chain starch. The former is unbranched helical structure; the latter is made of 24~30 glucose residues connected by α-1,4-glycosidic bonds, and α-1,6-glycosidic bonds at the branched chain. Straight-chain starch is blue when exposed to iodine, and branched-chain starch is purplish red when exposed to iodine. This is not the starch and iodine chemical reaction (reaction), produce interaction (interaction), but the starch helix central cavity just can accommodate the iodine molecules, through the van der Waals force, the two form a blue-black mismatch. Experimentally, iodine molecules alone can not make starch blue, actually make starch blue is iodine molecular ions (I3). Starch is a nutrient stored in the plant body, stored in the seeds and tubers, and the starch content is high in all kinds of plants.

Principle of starch airflow dryer

is a kind of large quantity drying equipment, which adopts the principle of instant drying, utilizing the rapid movement of heat-carrying air to drive the wet material, so that the wet material is suspended in the hot air, so as to strengthen the whole drying process, and to improve the rate of heat and mass transfer, and the non-combined moisture of the material after airflow drying can be almost completely removed (e.g.: starch and other materials with moisture content of feed ≤ 40% or so, and the finished output can be 13.5%, and the moisture content can be 13.5%. Finished product can be 13.5%), and the dried materials, will not produce the phenomenon of deterioration, the output can be compared with the general dryer drying has significantly improved, the user can be in a short period of time to achieve higher economic benefits.

Application scope of airflow dryer

Suitable for drying and dehumidifying powdered materials in industries such as pharmaceuticals, chemicals, food, building materials, plastics, etc., such as starch, fish meal, salt, distiller's grains, feed, gluten, plastic resin, mineral powder, coal powder, sugar chloric acid, A · S · C benzoic acid, 2.3 · acid, polyvinyl chloride, sodium sulfate, sodium metabisulfite and other materials.
