1. It should be ensured that the drier is clean and ,fit for use (see document entitled "Cleaning of Fluid Bed Drier).
2. The cleaned bags should be examined to ensure that they are free from holes and other defects.
3. The finger sleeves of the bag should be fixed to the respective hooks on the holding ring. The bag support frame should be inserted and the filter bag unit should be clipped to the retaining strap.
4. The cleaned bowl of the drier should be examined to ensure that the inner surface is clean and that there is no damage to the wire mesh sieve at the bottom. The bowl should be labeled with the name and batch number of the product being processed.
5. The wet material (to be dilled) should be loaded into the bowl and the mass spread uniformly. The trolley carrying the bowl should then be wheeled in and positioned beneath the sealing ring in such a way that the sight glass is in the front and the bowl raising lever on the base is accessible.
6. The earthling should be clamped on to one of the legs of the bowl trolley or alternately, it should be ensured that the bowl comes in contact with the eat1hing strap when pushed into position.
7. The bowl should be raised with the help of the lever. Where a pneumatic device is provided on the machine, it should be ensured that the bowl gets locked in position . and the bags are also held in place.
8. The heater should be switched on and the temperature setting on the thermostat adjusted to the required inlet air temperature. Where a time switch is provided the drying time should be set by turning the knob clockwise to the extent required.
9. The dampers should be adjusted to the required level and the locking nuts tightened to keep the dampers in place.

In the final stages of manufacture of bulk drugs, it is necessary to clarify the reaction mixture to remove extraneous and other suspended matter which may be present. This is done by means of filtration of the reaction mixture. This document gives the procedure for clarification of reaction mixtures by filtration through horizontal plate filters.
a) It is advisable to use freshly boiled and cooled purified water .
b) The suitability of the filter paper and filter cloth used for filtration must be ascertained before use.
c) It must be ensured that flexible tubings used in the filter asembly have been cleaned. Where they have been stored away after cleaning, the open ends should have been covered with polythene sheets. If this has not been done or there is evidence of dust on the tubings, they should be cleaned and dried before use.
a) All the removable parts of the filter assembly should be cleaned with hot water and steam. Hot water should be passed through flexible tubings followed by steam. The water should then be drained out.
b) The filter plates should then be assembled with the cloth filters or papers in place. The battery of filters should then be positioned in the filter chamber and the lid should be fitted.
c) The required lengths of flexible tubing should then be attached to both ends of the filter assembly.
d) The required quantity of filter aid or clarifying agent should be suspended in a suitable quantity of purified water. After it is uniformly mixed it should be pumped into the filter and circulated through the filter unit until a uniform bed is formed on the filter and the water coming out of the outlet end of the assembly is clear .
e) The bed should be washed with fresh quantities of purified water until the pH of the water from the outlet is the same as that of the feed water (range 5.5 to 6.5)
f) The pump should be stopped and the water in the filter assembly should be drained out.
4.1 The inlet tubing should be dipped into the product to be filtered. The outlet tubing should be placed in a clean container and the pump should be started.
4.2 The air vent should be closed after air is removed from the assembly and the liquid starts flowing thorough the outlet tube.
4.3 The first few liters of liquid should be discarded as it normally consists of the product diluted with water trapped in the filter assembly.
4.4 The clarity of the first few litres should be checked and if found satisfactory, the filtered liquid should be returned to the main product tank.
4.5 Filtration should continue and the clear product should be collected in a clean dry tank. During filtration the clarity of the liquid should be checked at suitable intervals.
4.6 If the clarity is not satisfactory at any stage, the collection of filtered liquid should be stopped and the liquid in the assembly should be returned to the main tank.
4.7 The filter should be re-set as described
4.8 After filtration is over, the inlet valve should be closed and the pump stopped immediately. Pressure should be applied through the air vent and the filtrate should be collected and added to the main filtered bulk.
4.9 When air starts coming out, the outlet value should be closed and the trapped liquid in the assembly should be collected through the scavenger outlet.
4.10 Liquid coming through the scavenger outlet should be checked for clarity before adding it to the main filtered bulk.
4.1 The electrical connections should be removed and the tubings and filter assembly should be taken away for washing.

1.0 Procedures

a) Before Starting the Engine ,ensure the generator is set up for the correct voltage, Check owners operation manuals and wiring diagrams for the correct hook ups prior to starting the generators.

b) Ensure the generator output breaker is in the OPEN position.

c) Never start or stop a generator with the output breaker in the CLOSED position.

d) Check all liquid levels of the diesel engine: water, oil, fuel. Add any fluid if required.

e) Ensure the generator, radiator, and control cabinet louvers are open for proper air flow across the engine and generator.

f) While performing the generator checks, wear work gloves and safety shoes. When checking the battery, or adding water to it wear acid resistant gloves and safety goggles. Check Generator Voltage and Phase Rotation

g) Start the generator and check the generator voltage(all phases), cycles, and phase rotation. Adjust voltage with "Voltage Adjustment Knob", located on the control cabinet. d) If required, check phase rotation of generator and load.

h) Secure the generator.

i) Connect the generator to the load. Observe the phase rotation. Use proper bending and lifting techniques when handling cables.

Wear safety shoes and work gloves. Put on hearing protection when generator is running. When checking phase rotations if the voltage is greater than 300 volts, then personnel doing the checks will wear coveralls, hood,insulating rubber gloves and sleeves, safety glasses, safety shoes, and hard hat.

Close the generator output breaker in accordance with generator operation manuals.:

SOP :Basket Centrifuge


Filterable products are separated in a perforated basket. The liquid/solid slurry is introduced into the rotating body of the centrifuge via a feed pipe. The centrifugal force pushes the slurry to the side, forcing the liquid through the perforations in the basket while the solids are retained within by means of a fine screen or cloth.

The remaining solids (cake) can then be washed and spun at higher Cs to achieve a relatively dry cake. The resultant cake is then discharged through the bottom of the basket by means of a single motion plow mechanism.

  1. Install a clean filter bag
  2. Securing the lid
  3. Connect the three process lines on the cover,
  4. Start the centrifuge.
  5. Adjust the machine speed via the speed controller.
  6. When the tachometer indicates that the machine is at feed speed, the process slurry is introduced into the rotating bowl.
  1. Solid particulate accumulates in a uniform ring on the bowl’s inside diameter while liquid filters through the porous solid cake and exits the centrifuge discharge outlet.
  2. When the solids holding space is completely full, the feed is stopped, the washing cycle is started and adjusted to a higher speed to obtain the dryest cake possible.
  3. At the end of the cycle, the centrifuge is stopped and the filter bag with the solids is removed.


Use interchangeable solid or perforated baskets appropriately.
