FREEZE DRYER
FREEZE DRYER-STI-240
FREEZE DRYER

PRODUCT APPRAISAL/APPLICATION

Freeze Drying is a process of removing the moisture content from a biological sample while ensuring that the structural integrity of the biological product & its structure is preserved. Freeze Drier is designed & conceptualized particularly for removal of moisture from a biological sample without causing any change in its original characteristics. Apart from this, Freeze Drier has a variety of usages in the Food Conservation, Chemistry Lab & Pharmaceutical Research Institutes.

USEFULNESS OF FREEZE DRYING

  • Freeze drying process is used to stabilize samples for storage, preservation, or shipping.
  • It is particularity useful for heat sensitive samples.
  • Compared to other types of dehydration, lyophilisation causes less damage and allows for retention of structure and some activity or viability
  • Lyophilisation is appropriate for many biological samples including microorganisms, vaccines, pharmaceuticals etc

BASIC CONSTRUCTION

All purpose lab freeze dryer is a floor standing model mounted on swivel Castors for easy mobility. Outer body of the Freeze Drier is constructed out of thick Mild Steel Sheet/ PCRC sheet duly pre-treated with primers for rust proofing and painted with long lasting powder coating paint & housed in super steel structure frame. 

VACUUM DRUM

Vacuum Drum/Drying Manifold is made of Non Magnetic Heavy Gauge Non Magnetic Stainless Steel with Perspex top cover for 6 or 12 drying port manifold. Complete with Perspex / acrylic sheet see through top Lid for Drying manifold. Size of the Vacuum Drum is 22.5 x 25.4 cm (Dia x ht) & is made up of non-magnetic S.S. duly argon welded. Complete with 6/8/12 Quick seal valves/ports for manifold Drying.

VACUUM PUMP

Vacuum is achieved by means of a Direct drive Rotary Vane type Vacuum pump of double stage of 100 litres/ min with Gas Ballast having an ultimate vacuum 1x10 torr on pump head.

VACUUM INDICATOR

An efficient & highly reliable PIRANI Gauge/Electronic Indicator is incorporated in the unit for Vacuum indication/measurements.

CONDENSOR TRAP

For complete effluent removal a condenser trap all non-magnetic Stainless Steel duly argon welded & dished at bottom is provided in the unit.
For safety & to avoid damage to cooling line & also for utmost efficiency Refrigeration coils are bonded outside of condenser. Temperature up to (-) 40 deg C at ambient temperature of 20 Deg C is maintained through an Electronic Solid State DIGITAL TEMPERATURE INDICATOR - CUM - CONTROLLER. Complete with Perspex / acrylic sheet see through Lid for condenser.

TEMPERATURE COOLING (ECO FRIENDLY CFC FREE REFRIGERANT)

An energy efficient cooling unit using hermetically sealed powerful compressor is installed in the Freeze Drier. We use high end CFC free Quality Kirloskar/Equivalent make compressors conforming to latest international standards and guidelines. The entire refrigeration system is housed at the bottom for easy maintenance. 

Temperature  up to (-) 40 Deg C at ambient temperature of 20 Deg C is maintained through an Electronic Solid State DIGITAL TEMPERATURE INDICATOR - CUM - CONTROLLER.
