Description
The Armfield Laboratory Drum Dryer is designed for food, chemical and pharmaceutical research.
The equipment is supplied fully assembled and ready for connection to site services.
The liquid to be dried is fed into the valley created by the two drums, where it is applied to the drums as they rotate together. The dry product is removed by a knife on each drum.
The unit is constructed from stainless steel, providing hygienic surfaces that are resistant to chemical attack.
The drums are hard chrome plated to ensure maximum heat transfer and the ability to scale up results to production-sized equipment.
The main drive is shaft mounted and its speed is adjusted by an electronic inverter in the control panel.

Optional Accessories
-T32-20 Vapour extraction system
This is fitted above the dryer and draws the vapours produced when drying away through the fan and duct assembly
-FT32-21 Feed system
The stainless steel feed tank and variable-speed pump deliver the material to be dried through a flexible pipeline to the dryer feed.
-FT32-24 Feed Roll Assembly
This assembly of 3+1 feed rolls allows you to turn the double drum into a Single Cylinder Feed Roll Dryer, representative of production scale drum dryers.
-FT32-25 Feed System Mixer
A stainless steel, paddle-type mixer mounted on the feed tank on a hinged lid. This enables any particles in the feed to remain in suspension and reduces settling within the feed tank.
-FT32-26 Pressure Reducing Valve Assembly
This comprises a pressure reducing valve to reduce the incoming pressure of the steam supply to that necessary for the dryer.
Also included is a steam safety valve for safe discharge in the event of over pressurisation. This has a manual easing valve if needed to dissipate the steam safely.
