Lyophilization process and products obtained thereby

A lyophilization process which comprises dissolving a material in one or more solvents for said material to form a solution; forcing said material at least partially out of solution by combining the solution and a non-solvent for the material, which non-solvent is miscible with the solvent or solvents used and wherein said non-solvent is volatilizable under freeze-drying conditions. In addition, for hydrophobic and / or lipophilic materials, the anti-solvent can be omitted, and the solution of the material in the solvent can be subjected directly to freeze drying. The lyophilizates can then be reconstituted with typical aqueous diluent in the case of hydrophilic materials. Hydrophobic and or lipophilic materials can be initially reconstituted with propylene glycol and / or polyethyleneglycol to form a high concentration solution therein and this is further diluted for use with a diluent of Intralipid, plasma, serum, or even whole blood.

Method and apparatus for making crystalline PET pellets

A method and apparatus for underwater pelletizing and subsequent drying of polyethylene terephthalate (PET) polymers and other high temperature crystallizing polymeric materials to crystallize the polymer pellets without subsequent heating. High velocity air or other inert gas is injected into the water and pellet slurry line to the dryer near the pelletizer exit. Air is injected into the slurry line at a velocity of from about 100 to about 175 m3 / hour, or more. Such high-speed air movement forms a vapor mist with the water and significantly increases the speed of the pellets into and out of the dryer such that the PET polymer pellets leave the dryer at a temperature sufficient to self-initiate crystallization within the pellets. A valve mechanism in the slurry line after the gas injection further regulates the pellet residence time and a vibrating conveyor after the dryer helps the pellets to achieve the desired level of crystallinity and to avoid agglomeration.

Preservation by Vaporization

Significant research is being done to develop and improve delivery mechanisms for biopharmaceuticals and vaccines, including pulmonary (inhalation), nasal, transdermal, and oral alternatives. Market projections indicate that the delivery of proteins and vaccines by inhalation and oral formulation has become and will continue to be increasingly important. These delivery mechanisms, to be effective, will require better stabilization of the biologicals so that they can maintain potency and effectiveness at ambient temperatures for extended periods of time. The novel Preservation by Vaporization (PBV) Technology described herein provides cost-effective and efficient industrial scale stabilization of proteins, viruses, bacteria, and other sensitive biologicals, thereby allowing a production of products that are not possible to be produced by existing methods. The suggested new PBV process comprises primary drying under vacuum from a partially frozen state (i.e. slush) at near subzero temperatures followed by stability drying at elevated temperatures (i.e., above 40 degrees Celsius). The new suggested method can be performed aseptically in unit doze format (in vials) and / or in bulk format (in trays, bags, or other containers). The drying can be performed as a continuous load process in a manifold vacuum dryer comprising a plurality (e.g., 30) of vacuum chambers attached to a condenser during the drying.
