A Brief Guide To Freeze Drying

Freeze-drying—technically known as lyophilisation, lyophilization, or cryodesiccation—is a dehydration process typically used to preserve a perishable material or make the material more convenient for transport. Freeze-drying works by freezing the material and then reducing the surrounding pressure to allow the frozen water in the material to sublimate directly from the solid phase to the gas phase.

Properties of freeze-dried products:

If a freeze-dried substance is sealed to prevent the reabsorption of moisture, the substance may be stored at room temperature without refrigeration, and be protected against spoilage for many years. Preservation is possible because the greatly reduced water content inhibits the action of microorganisms and enzymes that would normally spoil or degrade the substance.

Freeze-drying also causes less damage to the substance than other dehydration methods using higher temperatures. Freeze-drying does not usually cause shrinkage or toughening of the material being dried. In addition, flavours, smells and nutritional content generally remain unchanged, making the process popular for preserving food. However, water is not the only chemical capable of sublimation, and the loss of other volatile compounds such as acetic acid (vinegar) and alcohols can yield undesirable results.

Freeze-dried products can be rehydrated (reconstituted) much more quickly and easily because the process leaves microscopic pores. The pores are created by the ice crystals that sublimate, leaving gaps or pores in their place. This is especially important when it comes to pharmaceutical uses. Freeze-drying can also be used to increase the shelf life of some pharmaceuticals for many years.

Pharmaceutical and biotechnology:

Pharmaceutical companies often use food freeze dryer to increase the shelf life of the products, such as vaccines and other injectables. By removing the water from the material and sealing the material in a vial, the material can be easily stored, shipped, and later reconstituted to its original form for injection. Another example from the pharmaceutical industry is the use of freeze drying to produce tablets or wafers, the advantage of which is less excipient as well as a rapidly absorbed and easily administered dosage form.

Freeze drying equipment:

There are essentially three categories of freeze-dryers: the manifold freeze-dryer, the rotary freeze-dryer and the tray style freeze-dryer. Two components are common to all types of freeze-dryers: a vacuum pump to reduce the ambient gas pressure in a vessel containing the substance to be dried and a condenser to remove the moisture by condensation on a surface cooled to −40 to −80 °C (−40 to −112 °F). The manifold, rotary and tray type freeze-dryers differ in the method by which the dried substance is interfaced with a condenser. In manifold freeze-dryers a short usually circular tube is used to connect multiple containers with the dried product to a condenser. The rotary and tray freeze-dryers have a single large reservoir for the dried substance.

A Brief Guide to The Tablet Coating Procedure

A lot of solid pharma dosage mediums are manufactured with coverings, either on the outer surface of the capsules, or on substances distributes within gelatin pills. Tablet coating caters a great deal of purposes:

• Safeguards the capsule form abdomen acids

• Safeguards the abdomen lining from volatile drugs like enteric covered aspirin.

• Offers a delayed discharge of the drug

• Assist sustain the shape of the capsule

Preferably, the capsule must discharge the substance steadily and the medication must be accessible for digestion beyond the abdomen. The covering can be formulated specially to control how quickly the capsule melts and where the accessible medications are to be immersed into the body following eating.

Several aspects can influence the end-use properties of pharma capsules:

• Coating procedure

• Chemical composition

• Storage & environmental monitoring

• Drying period

Coating procedure design and control:

Tablet film coating system happens in a regulated ambiance within a punctured revolving drum. Slanting baffled slotted into the drum & airflow within the drum offer modes of blending the capsule bed. Consequently, the capsules are raised and turned from the sides into the hub of the drum, revealing each capsule surface to a constant volume of deposited coating.

Then the liquid spray covering is dried onto the capsules by heated air driven via the capsule bed from an inlet fan. The flow of air is controlled for heat and volume to offer controlled drying & extracting tempos, and at the same time, sustaining the drum pressure a little negative relation to the room to offer an absolutely isolated ambiance to the operator.

Tablet coating tools may comprise coating pan, cartooning machine, polishing pans. Blenders & mixtures, mills, fans, steam jackets, homogenizers, exhaust & heating pipes, filters and scales. Table coating practice may comprise sugar coating or film coating.

The coating practice is generally a batch impelled job including the below mentioned phases:

• Batch identification & recipe selection

• Loading or dispensing

• Warming

• Spraying

• Drying

• Cooling

• Unloading

A control unit should thus offer adaptability in the way in which precise & recurring regulation of the coating ambiance is accomplished and will comprise the below mentioned features:

• Accurate loop control with set point profile programming

• Chronological control for complicated control strategies

• Recipe management system for simple parameterization

• Safe accumulation of online data from the coating unit for analysis & evidence.

• Local operator display with apparent graphics & controlled access to limitations.
