P1 Flashcards
The movement of a relatively large portion of the material being mixed from one location in the system to another.
Bulk transport
characterized by random fluctuation of the fluid velocity at any given point within the system.
Turbulent mixing
distinguished by the shape and pitch of the blades or by the type of flow pattern they produce
Impellers
What are the 2 primary components for batch mixing?
- A tank
- A means of supplying energy to the system
What are the three types of impellers?
Propeller, Turbine, Paddle
A circular disc with several short blades attached
Turbine
what is the maximum viscosity and slurry a turbine can take ?
7 pascals. second and slurry up to 60% solids
SAS 3: what type of flow is having the fluid or gas flowing parallel to the axis.
Axial flow
SAS 3: What type of flow is the ______ ____ impeller discharges the fluid radially at 90° to the shaft axis.
radial flow
are used in the manufacture of antacid suspensions, agar and pectin-related purgatives, and antidiarrheal mixtures such as bismuth-kaolin.
Paddles
this type of mixing equipment bring the fluid in mixing vessel in all parts including the jet itself.
Airjets
behave somewhat like propellers in that they generate turbulent flow in the direction of their axes.
cannot apply tangential flow
Fluidjets
For bulk fluid flow to be most effective, an intermingling must occur between materials from remote regions to mixer.
Baffles
what are the factors to consider in choosing mixer?
the materials to be mixed
viscosity
particle size
compatability
_______________ ___________ play a significant role in pharmaceutical manufacturing, particularly in the formulation and production of liquid dosage forms such as syrups, solutions, suspensions, and emulsions. A
Monophase system
