Vrieco-Nauta™ Vakuum Dryers |
The Vrieco-Nauta conical mixer can be operated easily as a contact dryer making this advanced maschine very suitable for drying and allied processes. Heat energi is basically transferred into the product through a jacketed vessel wall causing solvents or moisture residues to evaporate. A rotating screw orbits along the vessel wall and helps the vapors to escape to the surface providing at the same time a frequent exchange of particles in contact with the heated surface. A vakuum system keeps the vessel under constant vakuum and removes the vapors from the the vessel having separated dust particles from the vapors first in a dustfilter on the top of the vessel. The vakuum conditions within the vessel also reduce the saturated vapor pressure of the solvent and this makes drying at much lower temperature possible. For recovery of solvents a condensor can be installed together with a collection vessel.

 CT Dryer |
Drying time and progress of the drying process are dependent on the heat
conduction of solid particles and solvents, pressure and temperature conditions
as well as speeds of screw and arm.

In 1996, a new infrared heater was
introduced by Hosokawa Bepex to incorporate state-of -the art technology and add
a new dimension to the company's existing line of polyester crystallizers.
Using infrared lamps as its heat source, the heater offers minimum gas flow
demands and does not require a heat transfer medium for product heat-up.
The heaters are designed to provide focused radiation for high heat transfer rates while allowing the polymer chip to be agitated and conveyed at low RPMs to minimize fines generation. The precise control capability of the infrared heater provides superior response times and allows an immediate stop to the heat source during power failures.
The exceptional versatility of these
units results in a number of advantages, including the ability to segregate the
heating to allow for stepped temperature increases followed by annealing zones,
if desired. Employing such approaches may yield desirable chemical and physical
effects of polyester polymer that leads to improved product quality. Hosokawa
Bepex has two models available for testing at its Minneapolis facility. One unit
is capable of production capacities up to 400 lbs. per hour and the other up to
1,000 lbs. per hour.

Torusdisc® Dryer/Cooler |
 Torus Dryer/Cooler |
The Torusdisc®
Dryer / Cooler is a continuous thermal system that combines high heat transfer
rates with extended residence times. It is designed to gently process
powders,
pellets, cakes and slurries without buildup of sticky materials.

 Continuator Dryer/Reactor |
This
efficient piece of equipment is our customers' choice for processing products
requiring extended residence times coupled with low thermal input. The
Continuator®
Dryer / Reactor is typically used downstream of a Torusdisc® or
Solidaire® as a second stage dryer / reactor.Til toppen af siden |

Thermascrew® Dryer/Cooler |
 Therma Screw Dryer/Cooler |
The
Thermascrew®
is a hollow screw, jacketed trough dryer / cooler with 3 to 4 times more heat
transfer area than simple jacketed screw conveyors. Its twin screw design
provides excellent backmixing and recycle rates for sticky products.

This type of dryer is commonly referred to as a “gap” type
mill. It is
called a “long” gap mill because of the long annular gap path the process
material takes from the inlet to the discharge. By combining several operations
such as flash drying, de-agglomeration and surface coating into one operation, a
Mikro-LGM™ long gap mill eliminates the need for multiple material handling
systems which subsequently increases process efficiencies. |
| Typical Applications
Include: |
|
|
|
Mineral Fillers |

Pigments |

Cryogenic grinding of rubber and elastomers |
The Mikro-LGM™ long gap mill has
demonstrated superior performance over all other mechanical mills in reducing
grit from pre-sized and agglomerated powders. Typical results are less than 1
part per million (ppm) residue on a 44 micron sieve starting from a feed stock
with a residue of 120ppm.
This performance is
achieved with a powerful grinding mechanism coupled with a precision internal
air classifier. The air classifier is designed for a theoretical cut point of
2-5 microns, depending on the particle density. Rejected particles are forced
away from the classifier wheel and redirected outside of the mill back to the
material inlet using a patented re-circulation system.
