Simulation of drying process for a multi-zone belt drying process can be useful for optimizing the drying parameters,improving the drying efficiency,saving the consumed energy and ensuring the drying quality.

To belt drier, the drying effect is influenced by the material uniformity directly, so a distributor should be set between the feeding device and the drying belt of the drier.

Optimization for vacuum belt drying process of Panax notoginseng extract;

Optimization for vacuum belt drying process of Radix Salvia Miltiorrhiza extract;

A comparison was made of three drying technologies for carrot powder,including vacuum belt drying,vacuum microwave drying and air-drying.

The drying of calcium carbonate made with nano-technology is currently by the methods such as baking at baking shop,drying at rotating column,spraying baking,flash drying and band-type baking.
