INTRODUCTION

PRESS :

It is a machine by which we can do

cutting and non cutting process byapplying force without removing chip onmetallic or non metallic sheet.

So we can give final shape to the job.

CLASSIFICATION1. Manual Press:

foot press, arbor press & fly press

2. Power Press:crank press, eccentric press, cam press,toggle press, screw press, rack & pinion

press, hydraulic press, pneumatic press

FLY PRESS

A Fly Press is amachine tool usedto shape sheetmetal by deformingit or cutting it with

punches and dies.

GAP FRAME PRESS

A type of press with a C-shaped frame suspendingthe crown over the bedand an open portion in thefront. The open front of

the gap-frame press offerseasy access to the die set.

Boilers


10/18

Boiler is a closed vessel in which

the heat produced by the

combustion of fuel is transferred

to water for its conversion into

steam at the desired temperatureand pressure.

Broadly speaking, a boiler is a

device used for generating :-

a) Steam for power generation

b) Hot water for heating purpose

The Boilers may be classified as under:

Horizontal boiler, vertical or inclined boilers

Fire tube and water tube boilers

Externally fired and internally fired boilers

Forced circulation and natural circulation boilers

High, medium and low pressure boilers

Stationary boiler and portable boiler

Single tube boilers and multi tube boilers

Feed pump

Injector

Economiser

Air pre-heater

Superheater

Steam separator

15/18

The primary requirements of steam generators or

boilers are:

a) The water must be contained safely

b) The steam must be delivered safely in desired conditions

as regards its pressure, temperature, quality and

required rate

Drying

*- Drying is commonly the last stagein a manufacture process.

*- Dryingis the final removal of waterfrom material (usually by heat)

.Non

thermal drying* 1- As Squeezing wetted sponge2*-Adsorption by desiccant (desiccation) 3*-Extraction.

Purposes of drying

- In pharmaceutical technology, drying is carried out for one or more of

the following reasons:

1-To avoid or eliminate moisture which may lead to corrosionanddecrease the product or drug stability.

2-To improveor keep the good propertiesof a material, e.g. flowability,compressibility.

3-To reduce the cost of transportationof largevolumematerials (liquids)

4-To make the material easyor more suitable for handling.

5-Preservative.

6- The final step in: Evaporation- Filtration- Crystallization.

Classification of dryers

Based on solid handling(static bed dryer-moving bed-fluidized

bed).

Based on heat transfer(direct dryers-Indirect-IR or radiant heat).

Dryers for Dilute Solutions and Suspensions

The objective of these dryersis tospread the liquidto a large

surface areafor heatand mass transfer for collecting the dry

solid.

Twomain typesare used:

The first, spreadingthe liquid to a thin film.

The second, dispersing the liquid to a sprayof small droplets.
