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
Polyphase system is also known as?
multiphase or multiparticulate system
T/F: Continuous shaking DO NOT BREAK the phase to be dispersed and the dispersion medium.
F: Continuous shaking tends to break up not only the phase to be dispersed but also the dispersion medium, thus impairing the ease of emulsification
It has a number of blades that may be straight or curved, with or without a pitch, mounted on a shaft.
Turbine mixer
Its principle is the passage of the mixed phases of an emulsion formula between a stator and high-speed rotor revolving at speeds of 2,000 to 18,000 rpm.
2,000-18,000rpm
Colloid mill
MFR meaning
Master formula record
BMR meaning
Batch Manufacturing record
Twin shell blender in other word is?
Tumble blender
takes the form of a cylinder that has been cut in half, (45-degrees) then rejoined to form a ‘V’ shape”
Twin shell blender
It consist of horizontal cylindrical tank usually opening at the top and fitted with helical blades
Ribbon blender
T/F: tube mills grinds more finely than ball mills
T
It is commonly found in domestic kitchen and in the industry
Planetary mixers
SEMISOLID: This mixer deals with stiff paste and ointments
Sigma blade mixer
Suppository: This is designed for in-package molding of suppositories
Sarong SpA Semiautomatic Equipment
