Continuous Tray Dryer

Home / Products / Continuous Tray Dryer


A revolutionary concept in drying of powder, granules, pellets & tablets in a continuous, cost effective, efficient manner with minimum human interference.

In a Continuous Tray Dryer material charging is from top and from 01 plate to another plate it keeps on tumbling thereby all the portions of the material is subjected to hot air and dried product is disposed from bottom with no human interference thereby avoiding problem of contamination.

Continuous output can be achieved from continuous Tray Dryer enhancing overall production. The working principle of continuous Tray Dryer is a mixed system of tray dryer and conveyor dryer. The system has continuous trolleys. Products can be dried by using different air sections (bottom - top - right - left). Each trolleys stay at all of air sections by using continuous trolley system.

    Our expertise in formulation development extends to the development of all conventional dosage forms. Our strategic alliances broaden the scope to consider many Novel Drug Delivery Systems (NDDS), including transdermal & liposomal delivery systems. We consider multiple approaches to improve the bioavailability of drugs. We have expertise in improving delivery of poorly soluble/ permeable drugs and the capability to screen potentially innovative drugs based on pharmacokinetic properties. We possess pelletization, drug-layering, particle-coating and other technologies to achieve extended release profiles for tablets or capsules.


    Our analytical development services include assay and RS method development and validation, dissolution method development and validation, stability studies as per ICH guidelines, polymorphic form characterization (DSC/TGA/XRD/Microscopy), cleaning validation studies and HPLC to UPLC method conversions.
