SCHEDIO - Isolator - S30C

SCHEDIO ISOLATOR, MODEL S30C

Powder grinding and dosing system with double isolator. This type of plant is recommended when, starting from products with a particle size down to a few millimetres, the customer wants to achieve a medium fineness in the order of 300-500 microns, and subsequently dose the product into aluminium bins of different volumes.

The pneumatic conveying and powder dosing system in isolator is designed to interface with a mechanical mill for grinding dry solid powders under aseptic conditions and with an adequate degree of containment.

Composed of

1. Milling Isolator

• Containment isolator with radial edges r=20mm.
• Window sealing is ensured by means of inflatable seals. Pharmaceutical design to ensure quick and effective cleaning.
• Liquid drainage through drain fitted with automatic valve. Internal lighting by means of LED spotlights, externally mounted.

Equipped with:

a. connection for exhaust filter differential pressure measurement, HEPA filtered

b. connection for particle counter

c. connection for microbiological counter

d. connection for mechanical mill feed cone

2. Dispensing Isolator

• Dispensing isolator with rounded edges r=20mm.
• Window sealing is ensured by means of inflatable seals. Pharmaceutical design to ensure quick and effective cleaning.
• Liquid drainage through drain fitted with automatic valve. Internal lighting by means of LED spotlights, externally mounted.

Equipped with:

a. connection for differential pressure measurement, HEPA filtered

b. connection for particle counter

c. connection for microbiological counter

3. Pneumatic transport

• Pneumatic conveying works under vacuum. The product is sucked in by a cone that collects the ground product from the mill. The product is transferred through a flexible connecting pipe, complete with tri-clamp fittings, into a cyclone filter with filter cartridge.
• Side channel suction blower made of aluminium alloy for quick and flexible control of the suction pressure.
• The motor is controlled by an inverter located in the main switchboard. The fan is positioned on the dispensing isolator platform.
• Motor power l.5 kW., maximum flow rate at glove removal 210 Nm3/h.
