Water-dispersible granules, also known as dry flowables, are like wettable powders except instead of being dustlike, they are formulated as small, easily measured granules. Water-dispersible granules must be mixed with water to be applied. Once in water, the granules break apart into fine particles similar to wettable powders. The formulation requires constant agitation to keep them suspended in water.
The percentage of active ingredient can be high, sometimes as much as 90 percent by weight. Water-dispersible granules share many of the same advantages and disadvantages of wettable powders except:
They are more easily measured and mixed Because of low dust, they cause less inhalation hazard to the applicator during handling Water dispersible granules can be made by several techniques. The most common ones include:
Extrusion – to produce cylindrical pellets UMANG PHARMATECH® offers various designs of extrusion basket extruder for low pressure extrusion, die roller extruder for high pressure extrusion. and cone extruder for moderate pressure extrusion. We tailor our needs and machines as per customer end product quality and testing parameter requirements.
API (Active Pharmaceutical Ingredients) manufacturing requires that special attention be paid to processing equipment design, hygiene and safety.
Pellet processing is accomplished with several of our products, including the Axial, cone, Radial, Die roller, mixer cum extruder, basket models.
UMANG PHARMATECH® advanced pellet technology and superior engineering provide unparalleled processing efficiency exceptional product quality
Successfully scaling up to full production means replicating your pilot results. How do you do this? The key is to use lab milling equipment that exactly
Particle size is a critical parameter in material properties. Monitoring and measurement of grain size distribution during processing is critical to successful product.
High shear granulator is the new mixer range that builds on the proven Umang technology and its benefits. Similar design of process bowl, mixer and chopper ensures that process
Twin Screw extruder is widely used for making pellets of different sizes starting from minimum 400 microns to maximum 2000 microns.
Integrated Mixer & Extruder is a compact design equipment with production capacity of 150 kgs of pellets per hour on continuous basis.
Die Roller Extruder as two rollers one is perforated and the second is knurling roller both are horizontally placed with minimum gap of 0.3mm.
The process involves the deposition of successive layers of an active compound onto nonpareil seeds resulting in the formation of uniform size pellets.
