UNDERSTANDING ON WORKING PRINCIPLES OF SIFTER (VIBRATORY SIFTER):

VIBRO SIFTER, VIBRO SCREEN: Vibro separators are circular gyratory screens used to separate solids from solids and liquid from solid. Vibro Sifter consists of Specially Designed Motor mounted vertically at the center of the base plate of the Screen. The Screen is in between feeding hopper and bowl. The material is fed on to the … Read more

COMPRESSION PROCESS IN PHARMACEUTICAL MANUFACTURING

TABLET COMPRESSION: Reducing the bulk volume of a powder by applying mechanical force so as to form a defined shape of desired weight and strength is called ‘Compression’. Tablet compression is the process of squeezing powders together and driving out the air between the particles, resulting in a compressed Tablet. WHY COMPRESSION? TABLET PRESS OR … Read more

BLENDING PROCESS IN PHARMACEUTICAL MANUFACTURING:

BLENDING PROCESS: Blending of solid particles refers to mixing of solids with the aim of attaining a uniform composition throughout the mix. In powder blending two or more dissimilar particulate solids are blended to give a random mix. Objective of blending is to form a homogeneous final product from two or more dissimilar raw materials. … Read more

MILLING PROCESS IN PHARMACEUTICAL MANUFACTURING:

MILLING PROCESS: Milling process is also called as ‘screening’ and ‘sizing’ process. Milling is employed between RMG and Blending to crush the larger particles from granulation into uniform small particles which meets the process requirement. Milling isperformed to remove lumps, improve flow, reduce segregation and to control the particle size. Milling is performed by using … Read more

GRANULATION PROCESS IN PHARMACEUTICAL MANUFACTURING:

Granulation is required to improve the flow of powder mixtures and mechanical properties of Tablet. Granulation is the act or process in which primary powder particles are made to adhere to form larger, multiparticle entities called granules. It is the process of collecting particles together by creating bonds between them. Bonds are formed by compression … Read more

Unit Operations during manufacture of Tablets:

Unit Operations: The manufacture of Tablets is a complex multi-stage process under which the starting materials change their physical characteristics a number of times before the final dosage form is produced. Numerous unit operations are involved in making Tablets including sifting, mixing, granulation, drying, sizing, blending, lubrication, compression and coating. DISPENSING OF RAW MATERIALS (API … Read more

DETERMINATION OF CAPSULE SIZE FOR FORMULATION:

Formulation of Capsules includes active ingredient and excipients (Fillers, Disintegrant and Glidant / Lubricant). Particle size distribution (PSD) and bulk density (BD/TD) of API/Excipients is important parameter in the selection of capsule size. Determination of appropriate capsule size for formulation: Blend with BD 0.4 g/cc and fill weight 200 mg to filled D= M/V     0.4 … Read more

Solid Dosage Form – Capsules:

CAPSULES: Capsules are solid dosage forms in which medicinal agents are enclosed within hard or soft soluble shell of gelatin. The capsules are regarded as container drug delivery system that provides a tasteless/odorless dosage form without need for secondary coating step. Advantages of Capsules: Disadvantages of Capsules: TYPES OF CAPSULES: Capsules can be broadly classified … Read more

Solid Dosage Form – Tablets

TABLETS: Tablets are the solid pharmaceutical dosage forms containing drug substances with or without suitable diluents and prepared either by compression or molding methods. Advantages of Tablets: Disadvantages of Tablets: EXCIPIENTS USED IN THE MANUFACTURE OF TABLETS: In addition to the active ingredient, solid dosage forms will also contain a range of substances called excipients. … Read more
