Introduction: Descriptions♦ The machine adopts full close structure with primary middle and high effect air filter to fit one hundred thousand grade requirement, the tower body is provided cool air jacket to make wall temperature less than80 C ,when the material s…
traditional Chinese medicine is an application of centrifuge atomizing technique.It also uses high-speed atomizer to make liquid material into foggy droplet to contact with hot air fully to finish instant drying and get final powder product.♦ The HESDChinese herb extract spray dryer is specially designed to solved the problems which previous LPG spray dryer meets duringdrying herb extract and plant extract product as followings:
4.Low in output:RWSD-150 type dryer can only process 50-60kg/h of raw material liquid.
♦In view of above situation,according to properties and process requirements of traditional Chinese herb extract,our factory has researched and designed the special spray dryer for the extract liquid and got patents.It solves the historical difficult problems in drying the extract and product color after drying is good.The dried raw materialdoes not degenerate too.It raises the economic benefit for user greatly.
There are special features as below compared to ordinary LPG type spray dryer:
1.Adopt three-grade air filter,the inlet air reaches one hundred thousand grade.
2.Adopt wall cooling device,the temperature of inner wall will be less than80℃.Even if raw material stays on inner wall surface,it will not be burnt and softened.
3.Its whole volume is 3.5 times of standard LPG high-speed spray dryer.
4.Adopt quick-open washing device,it can meet requirements for varieties production,the CIP auto cleaning device can also equip if needed.
5..Adopt wet duster and no powder dust leak out.It is in conformity with the requirements of environment protection.
6.Air sweeping device is optional,the clean effect is satisfied for some product.
7.Adopt PLC control and touch screen system to display system processing.
8.Dehumidifier and centralized collect system can be used to avoid product re-wetting and softening.
1.The tower body is equipped with cool air jacket to reduce
inside tower temperature and eliminate product preheating and softening phenomenon.
2.The atomizer on top of tower is equipped with cooling device to reduce atomizer temperature,at the same time effectively eliminate material return to the top in eddy current and avoid
preheat coking phenomenon.
3.Tower body and pipeline is equipped with manual quick-open cleaning hole and drain hole,CIP automatic cleaning device can also equipped if needed.
4.A automatic control constant temperature feeding tank can be equipped.
5.Manual high pressure washing tools can be offered as accessories together with spray dryer.
6.All product contact parts are made with stainless steel (or whole parts with stainless steel)
7.Product collect way adopts two grade cyclones and water film duster.
8.Air inlet temperature is automatic and continuous control which is interlocked with feeding.
9.An air sweeping device can be optional for some product.
10.It can equip primary,middle and high efficient air filter to get one hundred thousand grade clean air.
