Development in vegetable-drying technique and its study trends

Developments in vegetable drying techniques such as hot wind at normal pressure, vacuum freezing, micro wave, far infrared rays and osmosis were described in detail. Relevantly, the trends in the drying theories of balanced moisture content, dynamics, stages, speed, models, quality control and so on, as well as humid air thermodynamics, mathematics and other relevant subjects were discussed. The paper indicated that controlling the processing scientifically and effectively, promoting the quality of products, developing efficient and low energy consuming drying techniques and equipments, producing new vegetables for special purposes, should be the main directions for research on future dehydrated vegetable production.
