Isolation of Active Pharmaceutical Ingredients (APIs): Extracting and purifying APIs from raw materials or fermentation broths.

Principles of Centrifugation

Centrifugation operates on the principle of centrifugal force, which is generated by rotating a sample at high speeds. This force causes particles in the sample to move outward, away from the axis of rotation, at a rate dependent on their size, shape, density, and the viscosity of the medium. The key principles of centrifugation include:

Centrifugal Force

The force exerted on particles moving in a circular path, directed outward from the center of rotation. The magnitude of this force is given by the equation:

Fc=m⋅r⋅ω2

where ( F_c ) is the centrifugal force, ( m ) is the mass of the particle, ( r ) is the radius of rotation, and ( \omega ) is the angular velocity.

Sedimentation

The process by which particles settle to the bottom of a container under the influence of gravity or centrifugal force. In centrifugation, sedimentation is accelerated by the application of centrifugal force, allowing for the rapid separation of particles.

Relative Centrifugal Force (RCF): A measure of the effective force exerted on particles in a centrifuge, relative to the force of gravity. RCF is calculated using the equation:

RCF=1.118×10⁻⁵⋅r⋅(RPM)²

where ( r ) is the radius of rotation in centimeters and ( RPM ) is the rotational speed in revolutions per minute.

Isopycnic Centrifugation: A technique in which particles are separated based on their density. The sample is layered over a density gradient, and particles migrate to the position where their density matches that of the surrounding medium.

Differential Centrifugation: A method used to separate particles of different sizes and densities by subjecting the sample to successive centrifugation steps at increasing speeds. Larger and denser particles sediment first, followed by smaller and lighter particles.

Principle of Perforated Basket Centrifuge

The perforated basket centrifuge operates on the principle of centrifugal force and filtration. It is designed to separate solid particles from liquids based on the difference in their densities. The centrifuge consists of a perforated basket that rotates at high speeds, generating a centrifugal force that drives the liquid phase through the perforations while retaining the solid particles within the basket. This process is particularly effective for separating crystalline substances from their mother liquor.

Construction of Perforated Basket Centrifuge

The construction of a perforated basket centrifuge includes the following key components:

Perforated Basket: The core component of the centrifuge, the basket is made from corrosion-resistant materials such as stainless steel, copper, or monel. The basket has a perforated sidewall that allows the liquid phase to pass through while retaining the solid phase. The size of the perforations is selected based on the size of the particles to be separated. If the perforations are larger than the particles, a filter cloth is used to line the basket.
Support Structure: The basket is mounted on a vertical shaft, which is driven by a motor. The support structure ensures the stability and alignment of the basket during operation. The shaft can be either under-driven (mounted below the basket) or over-driven (suspended from above).
Motor and Drive System: The motor provides the necessary power to rotate the basket at high speeds. The drive system can include belt pulleys, water turbines, or electric motors. The power requirements vary, with higher power needed for starting the centrifuge and lower power for maintaining operation.
Casing: A stationary casing surrounds the basket to collect the filtrate and direct it to the outlet. The casing also serves as a safety enclosure, preventing any spillage or contamination.
Inlet and Outlet Ports: The inlet port allows the feed material to enter the basket, while the outlet port collects the filtrate after it passes through the perforated wall.

Working of Perforated Basket Centrifuge

The working process of a perforated basket centrifuge involves several steps:

Loading: The feed material, which contains both solid and liquid phases, is introduced into the basket while it is stationary. The amount of material loaded should be optimal to avoid excessive strain on the basket during centrifugation.
Centrifugation: The motor is activated, and the basket begins to rotate at high speeds, typically around 1000 revolutions per minute (RPM). The centrifugal force generated causes the liquid phase to pass through the perforated wall, while the solid particles are retained within the basket.
Filtration: As the liquid passes through the perforations, it is collected in the casing and directed to the outlet port. The solid particles form a cake on the inner surface of the basket.
Drying: The basket continues to spin, allowing the solid cake to dry as much as possible. Higher speeds may be used to enhance the drying process.
Unloading: Once the centrifugation process is complete, the motor is turned off, and the basket is brought to a stop. The solid cake is then removed manually using a blade or scraper.
