Studies on production examples of vacuum belt drying technology in Chinese traditional medicine extract to promote the application of the new equipment vacuum belt drier in traditional Chinese medicine industry. With consulting 23 references from journals database

comparing with conventional technologies and investigating the development status of belt-drying technology at home and abroad

we summarize the optimal craft condition

including crawler speed

heating temperature

water content of the extract and feed rate by mathematical modeling

quadrature analysis and comprehensive analysis in criterion of product moisture

drying rate and drug content

and thereby lay the foundation for technology standards in this field. Vacuum belt drying technology is the most advanced drying methods which has the advantage of saving energy and achieving a higher active ingredient content. However

a generally accepted technical standard has not yet been formed. Therefore

development of computer analysis software and building up of automatic monitoring technology and on-line measuring technology are needed to be combined with to simplify the process optimization and expand the scope of application.
