Freeze Drier

INTRODUCTION

Freeze drying has been used in a number of applications for many years, most commonly in the food

and pharmaceutical industries. There are, however, many other uses for the process including heat-sensitive sample preparation, plant material research, the stabilization of living materials such as microbial cultures, long term storage of HPLC samples, preservation of whole animal specimens for museum display, restoration of books and other items damaged by water, and the concentration and recovery of reaction products.

Specialized equipment is required to create the conditions conducive to the freeze drying process. This equipment is currently available and can accommodate freeze drying of materials from laboratory scale projects to industrial production.

APPLICATIONS

Freeze Drying, or lyophilization as it is referred to in the Pharmaceutical and Diagnostic Industries, is a dehydration technique, which enables liquid or slurry products, which have previously been frozen to be dried under a vacuum. The applications of freeze drying are numerous, but is generally employed when the requirements demand:

• Preservation of temperature sensitive products, particularly those of biological origin, 
  such as enzymes, blood plasma, vaccines, etc.
• To achieve a chemical balance, such as for biological reagents.
• To provide a practical solution for certain delivery problems, for example, the packaging of constituents that cannot be mixed in the liquid state, but which are solidified in successive stages and then freeze dried.

• To implement an important stage of a product (such as concentration).
• To improve storage life and improved marketing of the end product.
• To resolve certain filling problems. It may be difficult, for instance, to divide several milligrams of powder into precise vial dosages, due to the difficulty of measuring tiny amounts, homogeneity, granulation, static electricity etc.. The distribution of the product from the liquid state eliminates such production problems.
• Product temperature sensitivity, and its relation to taste.
