INSIGHTS ON SOLID DOSE MANUFACTURING

SOLID DOSE MANUFACTURING SOLUTIONS

  • Flexible Containment Isolators provide containment standards better than can be achieved with Downflow Booth technology, and often compare favorably with a Rigid Isolator system.

  • Isotube is an effective option for the safe loading and charging of multiple drums of HPAPIs.  Compared to the DCS® Drum Containment System for safely discharging drums, it is the preferred choice when charging lumpy and agglomerated products as a lump breaker system can be included in the lower part of the discharge hopper.

  • Dec excels in providing comprehensive technical solutions for packing powders into bags and drums from process equipment discharge such as a dryer or a mixer, milling and dispensing to the final packing of the product.

  • Used GEA Mobile Minor Spray Dryer, Model MM-PSR, stainless steel construction, 0.8 meter diameter chamber, GEA Niro nozzle atomixer, cone bottom, with top expansion chamber, with inlet HEPA filter housing, cyclone fines collector, discharge filter housing, and .95 kw blower, control panel with Allen Bradley Panelview1500 HMI, project# 1093-2412, built 2017.

  • 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.
