Renin Angiotensin Mechanism.

Non-Perforated Basket Centrifuge.

 

Centrifuge:

  • The equipment used for the process of centrifugation is called a Centrifuge.

  • The centrifuges are of two types as following,

  1. Sedimentation centrifuge:L

  • It is a centrifuge that produces sedimentation of solids based on the difference in the densities of two or more phases of the mixture. 

  1. Filtration centrifuge:

  •  It is a centrifuge in which solids pass through the porous medium based on the difference in the densities of the solid and liquid phases.

Non-Perforated Basket Centrifuge.

Principle:  

  • This is a sedimentation centrifuge. 

  • The separation is based on the difference in the densities of solid and liquid phases without a porous barrier. 

  • The bowl contains a non-perforated side-wall. 

  • During centrifugation, solid phase is retained on the sides of the basket, while the  liquid remains at the top, which is removed by a skimming tube.

Construction:  

  • It consists of a basket, which may be made of steel or any other suitable metal. 

  • The basket is suspended on a vertical shaft and is driven by a motor using a suitable power system. 

Working:  

  • The suspension is fed continuously into the basket. 

  • During centrifugation, the solid phase is retained on the sides of the basket, while liquid remains on the top. 

  • The liquid is removed over a weir or through a skimming tube. 

  • When a suitable depth of solids has been deposited on the walls of the basket, the operation is stopped. 

  • The solids are then scraped off by hand or using a scraper blade.   

Uses:  

  1. Non-perforated basket centrifuge is useful when the deposited solids offer high resistance to the flow of liquid.

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
