Binder addition rate and time. 5 but predicts an inverse linear dependence of the critical size on the average shear rate.
The objective is to convert the often fine and cohesive active ingredient and excipients into more uniform free-flowing granules that are optimized for downstream processing.
Critical point in granulation. LIST OF CRITICAL PARAMETERS DURING GRANULATION. Cleaning of area prior to granulation. Absence of foreign particles.
At the critical point when Stder Stee a limiting granule size is defined as def __ act – 2ryStet pp12 5 Bo 5This equation is similar in structure to Eq. 5 but predicts an inverse linear dependence of the critical size on the average shear rate. Now lets discuss each of these points.
Definition of Wet Granulation. Wet granulation is the process of binding different powder particles together using adhesives or liquid solution. As you will learn later in this section granulation is a critical procedure in pharmaceutical and food processing industries.
End-point determination at the lab-scale level in terms of power torque or any other measurement tool provides valuable input on where to stop granulation at the larger scale. Excipients in Wet Granulation. Wet granulation is a multicomponent process and the materials include the API and excipients.
Wet granulation end-point as a factor in tableting optimization Agglomeration of particles in wet granulation have been studied extensively 24 79. The optimal end-point can be thought of as the factor affecting a number of agglomerate properties Fig8. With so many variables involved in a granulation process it is no wonder that more and.
Critical control points CCPs are steps at which essential control measures designed to prevent or eliminate a food safety hazard or to reduce it to an acceptable level are applied. In other words they are specific production stages where the implementation of appropriate control measures will ensure the elimination or minimization of a specific hazard. Particle size is critical in a granulator process solution because if the particles are too large or too small they do not have the product characteristics important to produce light powders into high density free-flowing granulates.
Dry mixing takes about 3-5 minutes to mix the ingredients wet mixing takes 5-10 minutes to make the wet mass of material while the granulation process takes 5-10 minutes to make 05 mm to 15 mm sized granules. Mixing time consumed in processing is depends. Spray Granulation FBE 1.

Inlet air flow rate volume temperature and dew point. Thus with high-shear granulation it is extremely important to determine and control the end-point of the granulation process to achieve critical granule properties such as size and density. A disadvantage of both low- and high-shear granulation is that water can encounter the components for a significant time leading to changes in the drug andor excipients.
Dry GranulationThe Definitive Guide Do you want to be an expert in dry granulation process. If yes then this is the BEST guide for you. I am going to take you through an in-depth analysis of critical aspects about dry granulation techniques.
From the definition basic principles advantages disadvantages machines practical applications to factors. The purpose of the first part of the study was to determine the end point for granulations with continuous binder addition by evaluating granule properties. The amperage curve was used to monitor the agglomeration process.
The strength and the size distribution of dry granules were measured at various time points. It was found that the weight percentage of granules within the size range from. Blended and used for granulation experiments.
In this dissertation parameters such as liquid-solid LS ratio wet-massing time and chopper speed were varied to produce granules in a face-centered DoE augmented with 3 center points. Granules produced were analyzed for granule size distribution porosity aspect ratio and Hausner ratio. Dry granulation is a great choice to produce solid oral dosage forms if cost and process efficiency are essiential.
BASF offers the most effective dry binders available along with all other functional materials and expertise required to help you develop your process successfully. One important and critical point to remember in this stage is that Lubricants are mixed at the end of the mixing process and after completion of mixing product is discharged from the mixer in containers and final yield is calculated and is mentioned in batch manufacturing record. This study has also investigated the possibility of adjusting the tableting parameters in order to account for an inherent variability of a wet granulation process.
Granulation and mixing scale-up was specifically addressed in numerous recent publications 29 17 49 83 84 97 130. How to Identify Critical Quality Attributes and Critical Process Parameters Jennifer Maguire PhD. Office of Process and Facility OPF OPQCDERFDA.
1 FDAPQRI 2nd Conference. North Bethesda Maryland. October 6 2015.
Opinions expressed in this presentation are those of the speakers and. Wet granulation is a process frequently employed during the manufacture of oral solid dosage forms. The objective is to convert the often fine and cohesive active ingredient and excipients into more uniform free-flowing granules that are optimized for downstream processing.
Granules that possess ideal properties result in efficient process function including high throughput and tablets of the desired critical.
