Promas Engineers Pvt. Ltd

 

The dryer cabinet is designed in such a way that the airflow inside the dryer has minimum resistance. Internal surfaces of the dryer are made with well-rounded corners with maximum angle so as to offer least resistance to airflow, resulting in less pressure drop across the corners. The outer body is also fabricated with rounded edges without steps from outside to have smooth finish. The inside fan & radiator / heaters are covered with SS / GI mesh to have safety in operation. The drying oven model having MS body from outside & SS body inside is provided with 150 mm SS collar around the door.

 

 

The shafts of circulation fan, the inlets & outlets of the radiator coil are sealed by food grade sealing pads which stops the leakage of hot air from the drying cabinet.

 

Leakages increase drying time of the product inside the trays of the dryer & in some cases cause the air contamination of air inside the dryer. Thus sealing helps to save the energy of drying process.

 

The inlet (suction) of the dryer is provided with 10 micron filter to avoid air contamination. The exhaust of the dryer is provided with either manual or motorized operated damper and can be operated precisely for various positions of the damper from the main control panel board.

 

The outer body is also polished to 180-220 grit finish with step-less body for GMP model tray dryers.

 

We offer both economy models and GMP models.

 

Economy models of Tray Dryer the inside SS sheets are of 18-swg, AISI 304/316, tag welded & mirror finished, while for the GMP models the inside of the dryers are made of either 14-16 swg thick sheet fully welded from inside and polished to mirror finish. Material of Construction.

 

The dryer are manufactured in various combinations according to the requirement & the products to be dried. For example:

The doors of the dyers are provided with groove & with hollow “D” shaped food grade Silicon / Neoprene gasket to have leakage proof door. The locks are either ball catch or bolt type lock arrangement.

 

All the dryers are provided with necessary control panel boards. The dyers are supplied with either FLP or NON-FLP controls & drives.

 

 

Air in the dryer is circulated by means of fan fitted on the side of the dryer. The fans are made out of AISI 304 / 316 or MS with SS / MS / EN8 shafts driven by suitable motors. The shafts are well balanced dynamically & are provided with balancing test certificates.

 

 

Tray sizes of 32” X 16” X 11/4” or 32” X 16” X 2” are manufactured out of 16/18/19 swg., AISI 304 / 316 or PP material. All the corners are rounded without any gap. The 18- swg trays are with bidding from the top, while 16- swg trays come without bidding, and are used for all GMP model tray dryers. The trays are polished to mirror finish. The trays with perforation are also supplied for bottle or vial dryers.

 

 

These are manufactured from heavy gauge rectangular pipes & SS angle with cross supports from at the back. The trolleys are provided with SS brackets & wheels, or PU wheels with S.S. brackets or CI castors as required. The front of the trolley is provided with pulling handles. The wheels are 2 nos. fixed & 2 nos. swivel type. The trolleys are also supplied in MS with heat resistant paint.

 

We supply the dryers with following sizes, which are standard model while the non-standard dryers are also designed and supplied as per requirement.

 

 

PromasTM has its own continuous R & D program to supply better-designed drying system. Our clients in pharmaceutical industries in particular have experienced in the recent past various problems while drying specific products, as per US-FDA requirements. The standard tray dryers have circulation fans, mesh guards, partitions etc inside the drying cabinet itself, which are cumbersome in maintaining the clean operation & avoid contamination.

 

Promas has, therefore, designed a dryer suitable for cGMP requirement wherein main body of the dryer is generally mounted on the floor while the heating arrangement with HEPA filter and other pre-filters are mounted on the top floor or the adjacent room. The hot air inlet pipe is brought in the room with insulation & cladding & fixed on the dryer from the top-side of the drying unit. The hot air pipe is connected in such a way that the air gets equally distributed all over the chamber and the same is exhausted from the opposite side, but from the top of the dryer.

 

The body of the dryer is designed is such a way that the side wall of the dryer on which the air from the pipe hits, is tapered towards bottom with specific angle & same is on the opposite side. Thus the uniform distribution of the air inside the chamber is maintained by adjusting the damper of the exhaust. The exhaust of the dryer is also provided with a fine filter, which prevents any foreign particles entering from outside atmosphere at low pressure.  The exhaust pipe is fixed at the top of dryer & in the opposite side of the inlet pipe & is insulated with SS cladding. The temperature is controlled by pneumatically or electrically actuated,  steam controlled valve with I/P converter & PID controller.

 

Promas also supplies dryer with force circulation for the standard tray by providing blower at the inlet. The dryer is supplied with electrical as well as steam heating arrangement in the same dryer according to the requirement.

It all began in the year 2001. Like an energetic toddler, we first learnt to stand erect, and then to walk steadily.  

Now it`s time to run and try to beat the pace of the world.

Built on an area of 10,000 sq ft, the Promas office and factory are located in a `state-of-the-art` facility at Navi Mumbai in the MIDC (Maharashtra Industrial Development Corporation (MIDC) area.
