Variable frequency drive: the operating speeds of the centrifuge are controlled by a variable frequency drive. The standard braking system for this model is dynamic braking
Taper lock pulleys: these pulleys are easier to mount and dismount
Cake washing nozzles: special spray nozzles with defined conical pattern spray are provided so that the entire surface of the cake is covered uniformly with minimal quantity while maintaining repeatable washing performance
Shaft protection sleeve: a stainless steel sleeve is mounted on the exposed part of the shaft to protect it from corrosion
Proximity sensor: to prevent the machine from being started while the lid is open a proximity sensor is installed
Gas tight design: the machine is constructed to retain a positive pressure of 400mm water column
Easy maintenance: the machine design affords minimal maintenance. Greasing points enable easy lubrication of the bearings

AGITATED NUTSCHE FILTER DRYER (ANFD)

Agitated Nutsche Filter Dryer (ANFD) are designed for operation where maximum percentage of liquid in a slurry is separated through mechanical means. The filter works as a completely closed system preventing cross-contamination, possibility of atmospheric pollution from toxic fumes/obnoxious smell generated from the slurry for processes in API, Herbal Extractions, Chemicals and Food Industry.

ADVANTAGES OF AGITATED NUTSCHE FILTER DRYER (ANFD)

Very high solvent recovery.
Eliminates Explosion/fire hazard from spillage due to closed system.
Drying under vacuum
Optimization of Manpower. All operations can be handled by a single trained person.
Very effective washing of cake due to re-slurring resulting in thorough particulate washing.
Reduces number of washes, and volume of wash liquor.
Possibility of doing reaction, filtration, washing and distillation in the same equipment
Available in special construction for sterile applications with high standard of particulate purity.

NOTE

Sizing, selection of configuration, M.O.C’s, methodology of filtration etc. are based on material characteristics and these are used for proper selection and design based on specific application requirements. Magtech has vast experience and Pilot Plant facilities which are offered.

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.

ROTARY VACUUM PADDLE DYER (RVPD)

Rotary vacuum paddle dryer is a jacketed / limpet coil cylindrical vessel with a large diameter hollow shaft. Attached to the shaft are hollow paddles 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 periods 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 also be done by 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 is provided in the area of gland packing or trunnions. Arrangements for nitrogen purging is provided. Bag cleaning arrangement with pulsation by Nitrogen jet injector is provided. Heavy duty trunnions and bearing support the hollow shaft (agitator) and the drive is provided by means of a hollow output gearbox. Provision has also been made to insert four breaker bars inside the dryer shell for particle size reduction. In special cases, stationary scraper blade can be provided to scrap 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 vapor 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.

SALIENT FEATURES

Almost 100 percent recovery of solvent
Low energy consumption

VACUUM TRAY DRYER (VTD)

VTD is suitable for drying of thermal sensitive materials easily dissolved polymerized or deteriorated under higher temperature. Sterilization can be conducted prior to the drying process during which no matter is allowed to enter the product. Static vacuum dryer eliminates the configuration damage of the drying materials, therefore widely used in pharmaceutical, chemicals and food industries etc.
