Our infrastructure is well-connected to the nearby transportation modes.

AGITATED NUTSCHE FILTER

Agitated Nutsche filters offer an economic operation

where the maximum percentage of liquid in a slurry

is separated through mechanical means. The remaining

moisture can be removed by evaporation to obtain dry

products.

It consists of a cylindrical shell with welded dished end at the

top and either a flanged and bolted dished end or a welded

dished end / flat welded end at the bottom depending on

process/customer’s requirements. The vessel is divided

into two compartment by means of a perforated plate, provided

with suitable filter cloth or porous tiles. An agitator of unique

can perform multifarious activities by manipulating its movement of vertical and rotational directions

simultaneously, by push buttons switches/PLC. The filter is

capable of operating under either pressure or vacuum or a combination of both.

OPERATION

Slurry is fed into the top compartment from where filtrate passes into the lower chamber en route to receiver. Solids

are deposited on the filtering media in the top compartment and take the shape of cake of a uniform thickness.

The agitator pushes the solid content in the slurry upwards by keeping it under suspension till maximum possible

filtrate passes through the filter bed. This reduces time and increases productivity. It then seals the cracks in the

cake, which develop after most of the filtrate has passed through, by smoothing the top surface of the cake. It also

squeezes out some of the moisture in the cake by slightly pressing the cake uniformly with the help of specially

designed blades.

After the initial solvent/mother liquor has been separated, sometimes it is necessary to wash the cake. The agitator

has been designed in such a way that after adding wash liquor on the cake, the entire cake can be re-slurried and

agitated, so that all the particles forming the cake can be exposed to wash liquor and be thoroughly washed. This

improves the quality of the finished products.

After washing and removal of wash liquor, the cake can be discharged through a quick opening side discharge door,

by rotating and lowering agitator in the discharge direction. No manual handling is required.

ADVANTAGE OF AGITATED NUTSCHE FILTERS

The filter works as a completely closed system, eliminating any possibility of atmospheric pollution from toxic fumes /

obnoxious smell generated from slurry.

• Very high solvent recovery is possible.

• Explosion or fire hazard on account of spillage is eliminated.

• Manpower saving. All operations can be handled by a single unskilled person with a little training.

• Very effective washing of cakes due to re – slurring resulting in thorough particulate washing and reduces number

of washes, and volume of wash liquor.

• Possibility of doing reaction filtration, washing and distillation in the same equipment. In some cases drying

operation can also be carried out in the same equipment. Heat transfer surface can be provided by means of a

jacket or limpet coils on the vessel walls. Indirect heating can be provided on the filter base and agitator.

• Available in special construction for sterile application with high standard of particulate purity

Rotary Vacuum Paddle Dryer

Rotary Vacuum Paddle Dryer is a jacketed cylindrical

vessel with a large diameter hollow shaft (Agitator).

Attached to the shaft are hollow paddle provided with

specially designed scraper blades, which scrape the

entire internal surface of the dryer and continuously

move and rotate the material thereby precluding the

possibility of material remaining in contact with hot

surface for protracted period of time.

The jacket and hollow shaft with paddles can be heated

with hot water, steam or any other thermal fluid capable

of providing a large indirect heat transfer area. Cooling

can be also be done by cold water, brine or any other

refrigerant through the jacket and hollow shaft.

Limpet coil can be provided in lieu of jacket, if liquid

heating medium is used. Hard facing of shaft provided in

way of gland packing areas of trunions. Arrangements for

nitrogen purging provided. Bag cleaning arrangements with pulsation by

nitrogen jet injector provided.

Heavy duty trunions and bearing support the hollow shaft (agitator) and

The drive is provided by means of a motor through reduction gears chain

and sprocket.

Provision has also been made to insert four breaker bars inside the dryer shell for particles size reduction.

In special case, stationary scrapper blade can be provided to scrape the rotating agitator, for highly sticky materials.

OPERATION

Slurry / wet cake is charged through the charging door while keeping rotation of the agitator on. Vacuum is then

applied to the Dryer along with dust Catcher (mounted on the dryer) Condenser and receiver. Heating medium is

passed through the jacket and agitator. Vigorous evaporation of moisture takes place under vacuum. The vapour

passes through the bag filters of the dust catcher, goes into the condenser and the condensate is collected in the

receiver. Evaporation under high vacuum and low temperature results in faster recovery of maximum solvents.

Adequate provision has been provided to cater for fluctuations in steam pressure / temperature, in condenser

cooling water temperature, moisture content of feed etc.

Dry product is discharged via the discharge valve by reversing the agitator rotational direction to “discharge”

direction.
