DESCRIPTION
The LYOQUEST freeze-dryer is constructed as a compact desktop version. The basic unit consists of a metallic box
with lateral access doors to perform maintenance tasks. The vacuum pump is supplied separately and is optional.
The control panel is located at the front.
LYOQUEST components:
•
A two-stage vacuum pump provided with a gas ballast or a bubbler (gas purging apparatus). When the pump is
switched off a closing valve isolates the pump from the freeze-dryer, preserving the latter's vacuum while
atmospheric pressure is re-established in the interior of the vacuum pump, so backlash of oil is avoided. An
exhaust filter is also included.
•
A refrigerating system, which cools the condenser coil to the working temperature. The condensation surface
has been dimensioned ensuring the condensation of the water vapor released by the products that are being
freeze dried. This prevents vapors from entering the vacuum pump. The refrigerating system is formed by:
- Compressor:
LYOQUEST-55: one-stage hermetic compressor, condensed by air.
LYOQUEST-85: two one-stage hermetic compressors, condensed by air.
- Condenser:
Material: AISI 316L stainless steel.
LYOQUEST models:
•
PLUS: Prepared to work with all accessories and heated plates.
•
NO PLUS: Prepared to work with all accessories, but not with heated plates.
