Product Description

What is Maltodextrin

Maltodextrin (MD) is a polysaccharide food raw material and a low-conversion product between starch and starch sugar. It is a white or slightly yellowish amorphous powder with no visible impurities, a special smell, and a non-sweet or slightly sweet taste.

Working principle

This machine is a novel horizontal intermittent type vacuum drying equipment. The wet material is conductively evaporated. The scraper stirrer continuously removes the material on the hot surface and forms a circulating flow in the container. After the water evaporates, Vacuum pump out.
Performance characteristics
This machine uses a large area of sandwich heating, heat transfer surface, high thermal efficiency.
The machine is set to stir, so that the material in the cylinder to form a continuous cycle of state, to further improve the uniformity of the material heated.
The machine is set to stir, so that the slurry, paste, paste material can be dried smoothly.
Adaptable materials
Medicine, food, chemical and other industries conduct the following materials drying:
Suitable for paste, paste, powder materials;
Heat-sensitive materials that require low temperature drying;
Easily oxidized, explosive, strong stimulation, highly toxic materials;
Material recovery requires an organic solvent.

Note: The amount of water evaporation is related to the characteristics of the material and the hot air inlet and outlet temperatures. When the outlet temperature is 90 o C, the water evaporation curve is shown in the above figure (for selection reference). As the product is continuously updated, the relevant parameters are changed without prior notice.
