Ideal Requirement of best Coating Facility

Spray Gun	Bullose 230, Pilot Type 59
Stand	for fixing spray gun
Air Compressor	with pressure gauge and air filters. Air pressure available should be 3 - 6 kg/cm2
Peristaltic Pump	Electrolab PP 20IV - with 4 - 6 mm ID silicon tube this ensure uniform spray through out process
Weighing Balance	Solution to be kept on balance for calculating spray rate/min

Process Variables to Control During Coating

¤ Revolution Per Minute (RPM) of Pan
¤ Spray Rate
¤ Spray pattern and distance between spray gun and tablet bed
¤ Inlet, Outlet and Bed Temperature
¤ Air Pressure

Important Hints

¤ Provide gentle stirring to the coating solution during spraying to prevent settling of some heavy pigments present in the solution.
¤ While using PROCOAT WT (white), prepare the solution 24 hrs. advance to get best whiteness.
¤ Some time grayish spots develops on tablet during coating due to friction between pan and tablets. In such condition coat the internal surface of pan by the same solution, dry the pan and then load the tablet for coating.
¤ PROCOAT can be used in any coating machines such as Conventional Coating Pan, Autocoater (like Ganson, Neocoat, Accella Coata etc.) & Fluid Bed Coater.
