1: Introduction
Congratulations on the purchase of a Labconco Extraction Freeze Dry system. The
Extraction Freeze Dryer is designed to aid in the production of bubble hash following a
solventless extraction of plant material. The refrigerant used in the refrigeration system
is HCRC-free so it will not endanger the environment. The unit is easy to install and
maintain. Proper care and maintenance of this product will result in many years of
dependable service. It is the result of years of experience in manufacturing laboratory
equipment, and users like you suggested many of its features to us.
This Extraction Freeze Dryer offers many unique features. To take full advantage of
them, please acquaint yourself with this manual and keep it handy for future reference.
Intended Use
The Extraction Freeze Dryer described in this manual is intended for use to facilitate the
lyophilization process.
Freeze Dry Process
Freeze drying is a process whereby water or other solvent is removed from frozen
material by converting the frozen water directly into vapor without the intermediate
formation of liquid water. The basis for this sublimation process involves the absorption
of heat by the frozen sample in order to vaporize the ice; the use of a vacuum pump to
enhance the removal of water vapor from the surface of the sample; the transfer of
water vapor to a collector; and the removal of heat by the collector in order to condense
the water vapor. In essence, the freeze dry process is a balance between the heat
absorbed by the sample to vaporize the ice and the heat removed from the collector to
convert the water vapor into ice.
Freeze Dry Rates
The efficiency of the freeze-drying process is dependent upon the surface area and the
thickness of the sample, the collector temperature and vacuum obtained, the eutectic
point and solute concentration of the sample. It is important to remember these factors
when trying to obtain efficient utilization of your Cannabis Freeze Dryer.
Up to the point of overloading the system, the greater the surface area of the sample,
the faster the rate of freeze drying. By contrast, for a given surface area, the thicker the
sample the slower the rate of freeze drying. This is because the heat of sublimation is
