Sieve Shaker

One of the crucial phases of the pharma production process is sieving or segregating particles of varied sizes. Sieving is a widely used analytical technique adopted by labs and manufacturers to determine the particle sizes ranging from micro to macro units, from coarse to fine powders. Sievers or Sieve shakers aid in segregating and eliminating any unwanted by-products that could mix up into the drug production.

How does a Siever work and look like?

Sieve Shaker: Automated Sieve machines are fine wires of stainless steel, brass or copper materials without any coating to prevent contamination of the particles. Sieve meshes are arranged in a stack with each mesh varying its pore size to allow the particles to pass through them to the next chamber. This allows the fine sized powders to collect at the bottom chamber leaving the bigger coarse powders in the upper meshes. The segregation is achieved by agitating the sieve machine – horizontal and vertical sieving are majorly used.

As chemical compounds and powders vary in density and sizes, it is required to analyze the particle nature based on their characteristics like shape, surface and size. Some labs use image processing to analyze the contaminants or particle size distribution which demands additional cost and time. Sieving is a cost-effective method to separate particles based on sizes. The major purpose of sieving technique is to extract information about any possible by-products, contaminants.

Types of Sieve shakers or Sieving machines

Depending upon the particle nature from granules to coarse and fine, and depending on the particle size determination, most pharmaceutical and research /analytical labs embrace using three varieties of Sievers – Mechanical, Vibratory and Sonic sieve shakers. These are highly capable to sieve and segregate particles ranging 50mm to 20 micrometers. Some sieving machines are also installed for wet and dry samples.
