Renin Angiotensin Mechanism.

Cyclone Separator.

 Cyclone Separator.

Principle:

  • It uses centrifugal force to separate solids from fluids. 

  • The separation process depends on particle size and particle density. 

Construction:

  • It is made up of a short vertical, cylindrical vessel with a conical base. 

  • The upper part of the vessel is fitted with a tangential inlet. 

  • The solid outlet is at the base. 

  • Fluid outlet is provided at the center of the top portion, which extends inwardly into the separator. 

  • Such an arrangement prevents the air short-circuiting directly from the inlet to the outlet of the fluid.

Working:

  • The solids to be separated are suspended in a stream of fluid (usually air or water). 

  • Such feed is introduced tangentially at a very high velocity, so that rotary movement takes place within the vessel. 

  • The centrifugal force throws the particles to the wall of the vessel. 

  • As the speed of the fluid (air) diminishes, the particles fall to the base and are collected at the solid outlet. 

  • The fluid (air) can escape from the central outlet at the top.

Uses:

  •  Cyclone separators are used to separate solid particles from gases.

  •  It is also used for size separation of solids in liquids.

  • It is used to separate the heavy and coarse fraction from fine dust.

Variants : 

  • Cyclone separators are also used for size separation of solids suspended in a liquid such as water. 

  • Such separators are known  as wet or liquid cyclones.

  • One such apparatus used for this purpose Is : dorrclone.

Rate of Drying Curve.

  Definition Drying is defined as the removal of liquid from a product usually with application of heat. Rate of Drying Curve. Drying process can be divided into three periods Initial Adjustment Period. Constant drying rate period. First falling drying rate period. Second falling rate period. Initial Adjustment Period (A-B): Also called the “ Heating up” period . In this period the substance gets heat and increases in temperature. Drying has not yet started. Constant drying rate period (B-C): During this period the temperature of the solid and the rate of drying remain constant. The moisture evaporating from the surface is replaced by water diffusing from the interior of the solid at a rate equal t o the rate of evaporation.  The moisture content at the end of constant rate (point C) is referred to as the critical moisture content (CMC).  At CMC, dry spots start appearing and drying rate starts falling . First falling drying rate period (C-D): This period is also called the period of

Heat Exchangers and Heat Interchangers.

  In pharmaceutical industries many types of equipments are used for transfer of heat, they can be classified as follows, Heat Exchangers. Heat Interchangers. Heat Exchangers: These devices are used for transferring heat from a fluid (Hot Gas or Steam) to another fluid (Liquid) through a metal wall. Heat Interchangers: These devices are used for transferring heat from a One liquid to another liquid or one gas to another gas through a metal wall. HEAT EXCHANGERS; The equipment used for heat transferring are known as heat exchangers. Some of the processes that involves heat transfer in pharmaceutical industries are: Preparation of starch paste (in steam jacketed kettle). Crystallization. Evaporation. Distillation.  Classification of heat exchangers On the basis of transfer of heat, heat exchangers are classified as: Direct transfer type:  The hot and cold fluids are separated by a metal wall through which the heat is transferred from hot fluid to cold fluid. E.g. shell and tube heater,

Flash Distillation.

  Principle: When a hot mixture is allowed to enter from a high-pressure zone into a low pressure zone, the entire liquid mixture is suddenly vaporized. This process is known as flash vaporization .  During this process, the chamber is cooled.  The less volatile fraction is condensed and the more volatile component remains in the vapor phase .  This process requires time, hence liquid and vapor are kept in intimate contact until equilibrium is achieved. Flash distillation is also called equilibrium distillation because separation of two liquids takes place when liquid and vapor phases are at equilibrium. Equipment used for Flash Distillation: Construction: It consists of a pump, which is connected to a feed reservoir.  Pumps help in pumping the feed into the heating chamber.  The heating chamber is heat supplied by steam.  The other end of the pipe is directly introduced into the vapor-liquid separator through a reducing valve.  The vapor outlet is provided at the top of the separato
