Technical Data For Apd (Ref. Fig A)

These dryers give drying, mixing and breaking effects simultaneously. Wet cake or slurry is fed through charging door, while the agitator is rotating in clockwise direction, Vacuum is applied in the dryer and heating media is circulated in the jacket. Evaporation of moisture takes place under vacuum and vapors passes through the dust catcher into the condenser, where it is condensed and collected in the receiver. Dried material is discharged through discharge valve. The lump breaker rods are provided to achieve good drying effect. The unique quick opening discharge valve is operated by a hand wheel. This allows quick discharge of material and permits the dry product to be directly packed into convenient 25/50 kg bags or drums without loss of powder material.


This Machine can be provided in a single support (Cantilever) Design for Pharma, Clean room, Isolator applications. We can provide this cantilever design up to capacity of 6000 lits total volume.

be directly packed into convenient bags, drums or can be connected to powder transfer systems to discharge without loss of powder material. This machine can be completely integrated with isolation system so as to avoid and exposure of the user to the potent product thereby providing complete operator safety


Drying of granules, Powder of chemicals, Pharmaceuticals, Bulk drugs, Pigments, Dyestuffs, Fish & Sea food under vacuum. Size available from 100 liters to 25,000 liter

Salient Features

Higher thermal efficiency due to the stirring action of product. high vacuum application and greater heat transfer area
Improved product quality due to low temperature drying.
Full recovery of solvent is achieved.
Breaker bars are provided to break the lumps and disintegrate the particles size.
Stealite or S.S. Surface is provided at gland packing area of shaft for its long life.
Nitrogen purging arrangement is provided if necessary in stuffing box and at discharge point.

Dust catcher cleaning arrangement with pulsation by nitrogen jet or air jet injector is provided.
The design of paddles is such that reversal of electric motor direction is not necessary for discharging product. Hence the life of motor, gear box and equipment is increased.
Dish end design is also manufactured on request.
Sealing either stuffing box or mechanical seal with thermo-siphon arrangement.



1.Isolater Compatible
ANFD's are available in variants compatible with barrier isolation systems at the discharge. This allows handling of Cytotoxic/ Potent products with operator safety. Additionally, these can be combined with automatic packing systems further downline. Also lab scale ANFD models are available for R&D purposes.

2. Sterile Construction
Sterile application ANFD models with completely automated SIP/CIP & operation cycles, sintered cartridge filter media, metal to metal sealing are also available.


3. Special Heel removal discharge valve 2
A specially designed quick openable discharge valve which allows much closer access to interior of machine for heel removal is also available


4. Special Quick detachable designs for bottom
a) Super ‘C’ Bayonet
This design is similar to a TC clamp design but hydraulic operated. This facilitates easy and fast bottom bed detachment for filter cloth & product change over. This design is good for vacuum and very low pressure application


b) Teethed Bayonet
This desigTn has teethed body flanges, which are hydraulic operated and this is a ‘Positive Locking’ design. It facilitates easy and fast bottom bed detachment for filter cloth & product change over. This design is good for vacuum as well as high pressure applications.
