matic press-out system, whereby the
mill base is pressed out to ensure that
the dispersed product can be almost
completely regained with minimal wastage.
The product sample is conveyed
through the horizontal milling chamber
with minimal clearance volume by a
spiral conveyor, which is connected to
the milling rotor, while the separation
of the mill base is made by a dynamic
gap. The mill features a wear-resistant
stainless-steel milling chamber and a
milling rotor made of hardened nitride
steel. Shaft sealing is provided by a
mechanical seal with integrated pressure
system and cooling. An explosionproof,
ATEX-approved version is also
available. - Fullbrook Systems Ltd.,

New online configuration tool
for ATEX conveyors
Until now, ATEX gas-and-dust certified
versions of this company's vacuum
conveyors were only available by
special order. Now, users can visit the
company's website and configure the
most suitable version of its piFLOWp
(photo) or piFLOWt conveyors online.
With these ATEX-certified conveyors,
all plastic and rubber parts - including
the filters and seals used between
sheet-metal parts - are made of
dissipative (antistatic) materials. All
complete modules or units are fitted
with seals of synthetic rubber (nitrile
butadiene rubber), which have antistatic
properties. Over 300 different
configuration options for complete
conveyors are possible. - Piab AB,

The first tube connection with
Hoerbiger Safety Solutions

a consistent hygienic design
The new stainless-steel connector
of the CleanLine series (photo)
fulfills all of the important criteria for
use in the food processing industry,
and is constructed entirely according
to the regulations of the European
Hygienic Engineering & Design
Group (EHEDG). On the outside and
top, it is completely sealed by FDAcompliant
seals made of ethylene
propylene diene monomer (EPDM).
The outer contour is rounded and
micro-machined to minimal roughness
(Ra <0.8 µm) to prevent any
accumulation of impurities and also
to facilitate cleaning of the connection.
The same applies to the inside
of the connection, which is manufactured
from stainless steel 1.4404. It
is completely free of dead zones and
can be cleaned simply by flushing.
The inside is hermetically sealed by
two seals so that no liquid can penetrate
the connector from outside. -

Heat exchangers for
demanding hygienic applications
With a design pressure of up to 21
bars (305 psi), the FrontLine gasketed
plate heat exchanger (photo) allows a
flexible design with plates tailor-made
for demanding hygienic applications.
The plate pattern, the channel depth
and the overall dimensions are designed
for gentle, uniform heat transfer
for sensitive dairy, food, beverage
and personal-care products. The
FrontLine can be configured with different
sections, using plate and gaskets
in different materials with several
types of connections making the final
unit suited to users' specific processing
tasks. A unique herringbone
plate pattern with optimized pressing
depth and plate material provides
gentle, uniform heat transfer of sensitive
hygienic products. FrontLine
is also designed with a wide stream
plate for product containing particles
or fibers, such as fruit juices. - Alfa

Lowering operating costs with
active grounding protection
To ground and monitor multiple pieces
of equipment, such as loading and
mixing stations for tanks or railway
cars, a large number of conventional
static ground systems would normally
be required to provide adequate protection
against incendive electrostatic
sparks. In addition to these flammable
liquid and gas applications, powder
processing equipment, such as fluidbed
dryers and micronizers, typically
require multiple grounding systems to
adequately protect potentially explosive
dust atmospheres. The EarthRite
Multipoint II (photo) allows up to
eight individual pieces of equipment
