This technical drawing details a complete industrial vacuum tray dryer system designed for pharmaceutical applications, with a 96-tray capacity and 5 sq.m heating area. The assembly features a vacuum chamber constructed of 10mm thick SS316 stainless steel with vacuum-tight design rated for full vacuum to 1 kg/sq.cm working pressure and 3 kg/sq.cm hydrostatic test pressure.
Main Components:
- Vacuum Chamber: Fabricated from 10mm thick SS316 plates including side plates, back plate, and top/bottom plates with all internal surfaces mirror polished
- Heating System: 17 heating plates (1250mm × 1650mm × 29mm) made of SS316, with top heating plates at 4mm thickness and bottom heating plates at 3mm thickness
- Insulation: Chamber features external stiffeners (ISMC 100 × 50) and insulation stiffener covers (SS304, 2mm thickness)
- Door Assembly: Vacuum-tight door with silicon rubber gasket and SS304 construction
- Auxiliary Equipment: 150-liter capacity receiver, heat exchanger with 5 sq.m heat transfer area (shell side SS316, tube side SS304)
The system includes multiple process connections (designated N1-N16) for services including hot water inlet/outlet, vacuum line, validation port, vapor line, receiver vent, chamber drain, sight glass, and nitrogen purging. All nozzle flanges are designed to ASA#150 standards.
The heat exchanger specifications include a shell ID of 245mm × 1500mm length × 4mm thickness, 56 seamless tubes (19.05mm OD, 14G), and 5 baffles. The unit is designed for thermal circulation with steam/water at pressures up to 5 kg/sq.cm.
External surfaces are matt finished while all measurements follow metric standards with dimensions specified in millimeters. The design accommodates 6 trays per heating plate with a total system capacity for pharmaceutical drying operations.
