Basic Powder Flow Characterization [USP <1174>]:

A powder flow analysis is an indicator of how well formulation will release from the hopper during the tableting. It is important to know that the developed formulation is showing ‘Mass Flow’ or ‘Funnel Flow’ or ‘Rat Holing’.

Powder blend shows ‘Mass Flow’ when the entire solid bed is in motion during the discharge of material from the outlet. This is a ‘First-in-First-Out’ process. Hoppers offering ‘Mass Flow’ have steep and/or low-friction walls. This flow offers ‘No-Arching’, ‘Less Segregation’, and ‘Stable Powder Flow’.

When the hopper is not sufficiently steep and smooth enough to ensure sliding along its wall, the powder blend exhibit ‘Funnel Flow’. Such hoppers are sensitive to arching and ratholing. In this case, powder discharge from the hopper is not predictable.

Send a test sample of your powder to Natoli Scientific to get your formula characterized following USP <1062> Guidelines (Tablet Characterization Methods) that we have been practicing for over 25 years.

Natoli Engineering’s NP-P20A single-station hydraulic tablet press is a favorite for the production of injectable micropellets and for marginal formulations requiring deep-fill. The NP-P20A meets the FDA’s requirements for batch reporting and secure data management under CFR 21 Part 11 compliance.

Natoli Engineering is quickly becoming the leader in R&D tablet presses with this next-generation rotary tablet press. Designed to help solve formulation and scale-up challenges, the NP-RD30 rotary R&D tablet press replicates the design and functionality of a production press. The turret velocity of the NP-RD30 can reach that of production presses, meaning dwell time can be more accurately established during research and development.

Natoli Quick-Release Tablet Tooling allows researchers to test different dwell times during the tablet R&D process without the expense of buying several different sets of tools or the time needed to change complete sets of tooling or turret speed.

Through our Carlisle Precision Encapsulation Parts subsidiary, Natoli Engineering manufactures premium change and spare parts for most major brands of pharmaceutical encapsulation or capsule filling machines.

Natoli Engineering now offers AIM™ Data Acquisition & Analytical Software for the Natoli NP-RD10A research and development tablet press. The combination of AIM™ Software and this R&D tablet press enables the researcher to evaluate formulation properties and identify potential tableting issues—including capping, lamination, sticking/picking, and tablet robustness—during the tablet development process. Plus, the software can optimize tablet tensile strength and lubrication for successful large-scale manufacturing production.
