Due to the population’s growing needs, the pharmaceutical businesses are expanding dramatically. In this market, there has been fierce competition, thus it is imperative to produce excellent products efficiently with little downtime. State-of-the-art machinery types have aided the industry in offering services with ease, and a few machines and their operating principles are listed below:

Working Principle of Fluid Bed Dryer

The fundamental principle of fluidization, which is the process by which any material is changed from a static solid-like state to a very dynamic fluid-like state, underlies the operation of fluid bed dryers. A perforated distribution plate is used to introduce a hot gas of air into the area holding the material. The fundamental components consist of a chamber made of stainless steel and a removable perforated bottom. You put anything in the bowl that needs to dry. While the heat setters regulate the temperature within, air is allowed to enter the chamber from the bowl. Filtered air enters the room and moves through the bed. This device’s top is equipped with fans, and there is a control panel to regulate the temperature and other operational factors.

When air moves upward, it does so in a way that causes its velocity to be greater than the rate at which all of its constituent particles settle. With this mechanism and flow, the solid bed is transformed into a boiled liquid in the fluidic state, and all the particles get blown up and are suspended in the air stream. The material dries more quickly as a result of the heated air.

Working Principle of Octagonal Blender

For mixing and even lubrication of dry granules, the Octagonal Blender is a very effective and adaptable piece of blending equipment. Due to its moderate speed and octagonal form, the Octagonal Blender is only two-thirds full and produces great results. The material is evenly mixed in the top, which is polygonal and contains baffles. Its form allows it to mix huge amounts without affecting the particle structure. This blender comes with a bin charging mechanism and may also be adapted for vacuum charging. It also features replaceable baffles set on a rectangular shell. Either manually using the vacuum charger or taking material out of the bin, the substance that needs to be blended is charged. After that, the port is securely shut, and a predetermined timer is set for the blender. The product is released into the process containers by a butterfly valve.

Working Principle of Double Code Blender 

The most typical application for double cone blenders is the blending of freely moving materials. After the double cone has rotated, these solids, which belong to various densities, are blended together. This common and little design has its cone set in a thoughtful manner to completely exclude the possibility of overloading the mixture. The cone’s paddle-style barrier plans for uniform mixing inside the cone. A side-valve aids in the evacuation of the combined material. The time required for each mix depends on how challenging the item to be mixed is, but it features a polished surface for smooth operation. This equipment’s remarkable performance is due to its three-dimensional motion, which produces consistent and repeatable mixing results. A dual shell blender, which forms a V shape and can be utilised for least attrition when mixing delicate granules, can be employed.

Working Principle of Tablet Coater

The most typical function of a tablet coater is to apply a thin film of the coating material to a tablet’s exterior surface. On a moving bed and with the aid of a solvent and a hot air current, the coating material is applied. The coated tablets are placed in a drum that is continuously rotated in an orbital motion by the force of a streamlined plate. These tablets’ coating sprays as they are rotating in an orbital motion, preventing any extra coating from getting on the tablets. Air is forced into the drum by angled baffles and used as a medium to mix the tablets. The baffles also allow for the consistent coating of the tablets by turning them. Hot air from the partially finished perforated tablet bed is introduced during the spraying process, which speeds up the drying of the coating medium. For the best tablet extraction rates, the temperature and airflow are controlled.

Working Principle of Colloid Mill

Pharmaceutical businesses separate chemical compounds to reach the smallest possible state of the compounds. They do this by working with small compound particles. A colloid mill is employed in a variety of processes, including homogenising, emulsifying, mixing, and superfine grinding. The rotor-stator, which is housed in a cylindrical tank, serves as the foundational component of this mill. In order for the material to fit through this small path, the rotor and stator are positioned very near to one another. Shearing is the term used because the particles become exceedingly small and fine. The product is delivered to the space between the rotor and the stator after being loaded into a hopper. Both surfaces have metal tooth covers that can shear and cut through solids.

The Bottom Line:

Design and manufacture of equipment used in the pharmaceutical industry require specific consideration in order to prevent contamination and maintain quality in accordance with cGMP. When selecting one for the production line, the design, construction, and operating principles are all crucial.
