Agitated Filter is a closed vessel designed to separate solid and liquid by filtration under pressure or vacuum. The closed operation ensures odorless, contamination free and nonpolluting working conditions maintaining product purity and hygiene. The advanced technology of agitation and hydraulics used in the equipment makes it versatile and user friendly. The resulting wet cake can be reslurried and washed thoroughly with water or solvents unlike in” NUTSCHE” type filters or centrifuges. Wash liquid quantity can be controlled and recycled, reducing effluent load. The discharge of wet cake is automatic. If the process demands filtration in chilled or hot condition, it is also possible. Drying of wet cake is also possible when drying features are incorporated.
The equipment is functionally safe and easy to operate. It can carry out various phase of process operations, viz: Crystallization , filtration, extraction, Discoloration, Washing and drying. The number of conventional machines employed for filtration process are also reduced. It has multi- functional utility, saves on power, labor, floor space, material wastage and time.
The filter/filter dryer has wide field of applications in chemical, pharmaceutical, Agro chemicals, fine chemicals, and food industries. Sterilizable pharma versions are available for aseptic requirements.
CONSTRUCTION: Agitated Filter is a Cylindrical, Vertical closed vessel made as per pressure vessel codes. The vessel is fitted with plane filter media, either metallic or synthetic at the lower end of the vessel. Specially designed slow speed, robust Agitator assembly is mounted on vessel. The Agitator design adopted is advanced and unique to this system .The “ S” Type self centering blades are made from heavy sections to handle liquid as well as solids. It has four movement; each movement, either single or in combination is designed to carry out specific operations.
The movements of agitator are:
1. Clock wise rotation: For smoothing cake surface and compacting it during filtration.
2. Anticlock wise rotation: F or stirring near filter media to keep it clear of sedimentation, reslurring while washing and atomized discharging.
3. Upward movements: Operated by hydraulic cylinders at constant speed to assist mixing.
4. Down ward movement: Operated by hydraulic cylinders with variable speed to assist squeezing and discharge.
OPERATION/PROCESS:
CHARGING: Slurry is charged into filter preferably by gravity flow from Reaction installed above the filter or by slurry pump.
FILTRATION: While charging the slurry into the filter, filtrate will start passing through filter cloth by gravity. To enhance filtration rate and to keep filter media clean from initial sedimentation, the agitator can be brought down most position and keep on rotating in forward direction. The cake height can be built up in successive steps.
CAKE WASHING: Wash liquids is sprayed into the chamber on cake through a spray ring. The stirrer blades are lowered to agitated the slurry to obtain good cake washing. The wash liquid is sprayed repeatedly though the filter cake by the same driving force as used during the first stage filtration.
SMOOTHING AND COMPRESSION: At the closing stage of the filtration process described above, the stirrer blades are lowered on the cake surface. The specially designed hydraulic system, takes over to perform a systematic, efficient and productive smoothing of the cracks which appear in the cake, leaving behind low residual moisture 10to 20% less as compared to other conventional filters. This results in energy saving in drying process at least by40%.
FILTER CAKE DRYING: After the final wash, filtration and compression, the heating medium is fed into the limpet/jacket and the chamber below filter plate as well as Hollow shaft and Hallow Blade .The stirrer blades are lowered and the cake mass is agitated during the drying stage. The vapour can be removed under vacuum applied to the filter. Drying can be enhanced by purging a hot gas through cake.
PRODUCT DISCHARGE: The stirrer blades are rotated and lowered to cut away the upper surface off the filter cake. As the blades descend into the cake mass, the discharge value is opened and a controlled discharge of the cake is achieved.

Rotary vacuum paddle Dryer or Paddle Dryer is used to obtain dry Powder from wet cake or solutions. The efficiency is very high and the operating costs are low compared to other types of dryers. It is a closed system in which hot water ,steam, or hot fluid is used as a heating medium in the jacket, in the hollow paddle and in the hallow shaft. Dust collector, condenser, receiver and vacuum pump are part of the system. The continuous agitation by means of heated rotating paddles and minimum clearance between scrapers and heated walls provide a good heat transfer to the wet feed. This results in the solvent/moisture evaporating off and renders the wet material dry, to the required degree. The vapors formed are removed by means of vacuum. Absence of large air flows virtually eliminates dust problems and also the energy consumption remains low. Some of the salient features of a Rotary vacuum paddle Dryer made by us are described below

The Micronising Mill has many advantages over conventional comminuting equipment.
Temperature Accuracy : _+ 2 to 30C
FINISH : Internal 320 Grit Mirror Polish and Outer 180 Grit Mat Finish.
Description:
Micronising is a process extensively used by the pharmaceutical, chemical, agro-chemical, pigment and cosmetic industries for the production offline powders.
The MEPL Micronising Mill is suitable for virtually any materials requiting ultra fine grinding, whether in campaign or continuous production. Special linings are available for cohesive and for abrasive materials. This is best suited for heat sensitive materials, because the cooling effect of grinding fluid as it expands at the jets and material remains cool.
It is possible to produce powders that are predominantly below 5micron for use in.
The Micronising Mill has many advantages over conventional comminuting equipment.
Feed material is inspirited by venture into the cylindrical grinding chamber of the mill. Compressed gas jets, arranged tangentially around the grinding chamber, accelerate the particles, causing omter-particulate impact in the extremely turbulent zone close to the chamber wall. Intense velocity of the jets and the fluid energy is rapidly dissipated to the particles. Larger particles are retained within the outer circulating mass by centrifugal forces, while fine particles outgoing gas stream. The combination of centrifugal and drag forces operating within the grinding chamber provides an efficient classifying mechanism. An adjustable guard ring at the center of the chamber further restricts the passage of oversize particles before material and gas pass from the chamber, either to an integral cyclone or to a separate collector.
An Example of one product which is micronised in microniser model MEM 200G practical distributor.
90% < 5 micron
99% < 7 micron
100% < 10 micron
Max particle size = 9 micron in general input feed size of 100 mesh with air pressure of 7.5 kg/cm2, adequate quantity of air and controlled feed gives better results. Setting of microniser also plays an important role.
However, final results can be delivered by trail. Fineness and out put depend upon material characteristics and other factors.
Isolation technology has shown tremendous potential due to various technological development such as transfer, filtration, granulation, ventilation systems etc. Isolator means a physical barrier between a process and its operator. An isolator is closed system whose size and features very according to the type of application. With in this environment simple and complex operation can be carried out, either manually or automatically. These operations can be conducted in controlled atmospheres, at particle or microbiological levels. Control system, quality of air and type of gases used inside the isolator those are importance things for the successful implementation of isolation system.
