The scale-up of wet granulation processes is commonly divided into two categories: engineering and attribute-based methods. An engineering-based scale-up approach is a strategy based on dimensional analysis and an attribute-based supported on the principles of "equifinality", where process variables are adjusted to obtain equivalent granule attributes.
Three prominent approaches towards the production of granules are dry granulation (DG), wet granulation (WG) and melt granulation (MG) [4]. DG is defined as the aggregation process of initial powders in the absence of any liquids. This process takes place at high pressures to ease the particles bonding via direct contact to achieve the desired ...
The process of granules formation by wet granulation method was explained by Ennis & lister in 1980 & it is known as the Ennis mechanism of granulation or droplet nucleation mechanism.It is explained by the following stages,
The success of a wet granulation process depends on the use of an excipient with excellent binding and compaction properties. Mannitol is frequently used for this purpose in solid dosage formulations owing to its physicochemical properties; it is chemically inert and has good compactibility and low hygroscopicity. 1
This chapter focuses on wet granulation, where a liquid is used to form wet agglomerates, which are subsequently dried. It provides an overview of the many advances in …

Alternatives to Wet Granulation. There are a few alternative processes that can be used to produce granules, such as dry granulation, spray drying, and melt granulation. However, wet granulation is the most common process used in the pharmaceutical industry because it offers a number of advantages over the other processes. Advantages of Wet ...

Coldani a, ... The key finding of the first two process techniques was a migration of paracetamol from powdered agglomerates towards the larger ...
Wet granulation (also wet blending) in the high-shear mixer is a classic process for building up granules from powder. This process is used when rapid agglomeration to form relatively compact granules is desired and the solid, pre-applied starting materials have low adhesive properties of their own. Powdered substances, such as vitamins, trace ...
impact of wet granulation process parameters on the drug product quality attributes. The following steps were performed: ñ CQAs of the product were characterized, ñ process parameters (factors) of potentially critical impact on the CQAs were typed, ñ high and low levels were assigned to each factor, ñ experimental matrix was designed,
Dry Granulation and Wet Granulation In general, compound fertilizer granulation technologies can be classified into two types: wet granulation and dry granulation. ... In wet granulation process, the first 3 most commonly-used fertilizer granulators are rotary drum granulator, disc pan granulation machine, spray granulation machine and tower ...
The amount of water as a liquid binder is critical for the wet granulation process because excessive water might result in over-wetting, which was characterized by initial sharp rise of torque and then dropped significantly as the wet granules converted to slurry. On the other hand, inadequate water may generate weak granules .
Wet granulation is a size-enlargement process applied in many industrial fields, such as pharmaceutical, nutraceutical, zootecnichal, to improve flowability and compressibility properties of powders. In this work analysis of the particle size distribution (PSD) of granules was performed to understand the phenomena involved during the granulation process and to …
The influence of enzyme liquid binder properties on wet granulation process was evaluated at both micro- and macro-scales. The micro-scale phenomena, including binder droplet spreading on and penetration into the powder bed, as well as liquid bridge shape and force, were analyzed by introducing SiO 2 nanoparticles and SDS surfactant into the liquid binder …
The wet granulation process that occurs in high-shear granulators can be divided into three main stages: wetting and nucleation, consolidation and coalescence, attrition, and breakage. When the liquid binder is added to the powder mass, particles start aggregating and form some clusters (nucleation). ...
The authors also compared how quality-by-design concepts could be applied to the MADG process, the wet-granulation process, and the drygranulation process. View. Show abstract.
The amount of water as a liquid binder is critical for the wet granulation process because excessive water might result in over-wetting, which was characterized by initial sharp rise of torque and then dropped significantly as the wet granules converted to slurry. On the other hand, inadequate water may generate weak granules [29].
MECHANISM IN WET GRANULATION . Three steps in the process of wet granulation are wetting and nucleation, coalescence and consolidation, and attrition and breakage (Figure 1). Wetting is the process of infusing liquid into dry powder and distributing it uniformly throughout the material to establish liquid bridges between particles.
This document discusses optimizing a wet granulation process using high shear mixing. The process involves dry mixing ingredients, adding a binder like water or MCC, kneading the mixture using high shear, then drying and milling the granulated particles before characterization.

Learn how to make tablets by wet granulation, a process of size enlargement in which fine powder particles are agglomerated into granules using a granulating fluid. Understand the mechanisms, steps, and recent advances of wet granulation technology.
The process parameters in the high-shear wet granulation process might significantly influence granule size. Granule size distribution might be significantly related to desired qualities in key areas, such as product uniformity, dissolution, flow, hardness, and bioavailability. Granule size is also used to optimize downstream processing as it ...
In this case, granulation produces larger and rougher particles. thus dry manufacturing process is used to increase the flow properties by decreasing the particle surface and reducing the amount of dust granulation.
