Chinese Herbal Medicine Extract Spray Dryer

  Chinese herbal medicine extract is refined from root,stem and leaves of plants,and contains high sugar especially from alcoholization process,which is easy melted at high temperature,Normal centrifugal sprying cannot meet its drying requirement.For this reason,our company organized,a group of technicians to develop such a dryer especially used for Chinese herbal medicine extract after repeated calculations and countless tests on the basis of our experiences to make spraying dryer and collect advantages of same kind of dryers from oth domestic and abroad.It has been popularized and used by some famous medicine manufacturers such as Changjia Pharmaceutical Factory,Huiren Medicine Industry Co.in Jiangxi.Nanjing Tongrentang Pharnaceutical Co.etc.,and most safactory results have been received.

Modifications have been made when designing Chinese Herbal Medicien Extract Spray Dryer:
1.The diameter and height of the tower have be modified to ensure that powder cnnot reach at the wall of the tower before drying,and ensure that powder will have dwelling time in hot air to complete low-temperature drying.The wall of the tower ahs sandwich cooling device to ensure liquid materials not to be softened,melt or coked when they are stuck on the wall which will have partial high-temperature.There are air shocker on the cone body which has larger taper and can pulsate the tube by compressed air to shake down powder which is stuck on the tube.
2.All contact place inside the dryer have plain or round surface,and is ground and polished(fine polish over 10 )to avoid sand hole and dead angle etc.The contact surface is made of stainless steel to ensure materials free of pollution.The dreiving parts have good sealing to prevent water and avoid air leaking.Discharge pipes are connected flexibly for easy dismantling in order to meet GMP requirement.
3.There-stage air filters are used on air pretreatment system and air can be purified up to 100 thousand level.
4.PLC program control system circuit is used and cartonns of contact screen displays technological process.Variable data carries out automatic trace and regulation by fuzzy technique,the atomizer is adjusted stably by frequency converter,temperature of incoming air is adjusted by the power-regulator,precision can reach plus and minus two so as to largely reduce energy consumption.Incoming and outoing temperature as well as pressure inside the tower can be set up precisely.
