HECHT – We care.
As your reliable partner for
secure bulk material handling,
our family business stands
for tailor-made and efficient
solutions.

3. SAMPLING 3
Ensuring a continuous product quality is a key issue in many
industries. Quality must be guaranteed not only for food and
medicines, but also in companies whose employees deal with
toxic or explosive substances.
Regular sampling and product analysis are essential to detect
and react to quality deviations immediately. Samples must be
taken at exactly the right place, in the right quantity and at the
right time.
HECHT samplers offer simple handling and can be easily inte­
grated into your process. All samplers are robust constructions
designed for industrial use. Easy to dismantle versions allow a
comprehensive cleaning. System integrated versions for the
most diverse places and the comprehensive adjustability of the
systems ensure the best user-friendliness and process reliability.

4. The classification according to OEB (Occupational Exposure Band) considers
the toxicity of the pure substance. As a rule of thumb it can be said that the
more toxic the substance, the higher the classification. As a reliable partner,
HECHT is always available to answer all your classification questions.

Containment
during sampling
Particularly during sampling active substances, it is important to plan the sample
handling accurately, because the process-system has inevitably to be opened.
Besides the choice of the sampling system the right choice of the sampling bin
is particularly important, because you have another opened interface. For this issue
HECHT offers a huge range of systems and bins. WIP or CIP systems

Slide Sampler
The slide sampler is our latest development in the field of samplers.
It was especially designed to meet the high quality and accuracy
requirements of the pharmaceutical, chemical and food industry.
Due to the stable mechanics and the efficient mechanism the
sampler is the first choice when it comes to cost efficiency.

Screw Sampler
Whether for installation in silos or in downpipes – the screw sampler is the ideal
solution for a representative sampling of any kind of bulk material. A pre-installed
self-cleaning function guarantees the validity of the samples. Depending on our
customers’ requirements, we offer various connections for matching sample
vessels as well as different sealing valves.

Filling
HECHT offers various filling stations
for almost all purposes when it comes
to filling of Big Bags and small bins
like drums or boxes. Also a contin­
uous liner can be used. Depending
on the bin sizes, the space conditions
given, the quantity of bins to be
filled or the respective weighing unit
needed, we offer individual solutions.
Numerous special applications or
customized versions for all require­
ments of your production can be
realised by using our solutions.
Discharging
Bulk solids are mostly transported
and warehoused in Big Bags, con-
tainers or small bins like drums or
sacks.Therefore, different dischar-
ging stations are needed for further
processing. In addition, for planning
and design, several important facts
must be considered.
Depending on the necessary filling
capacity, the respective Containment
level and implementation of an
optional weighing or dosing function,
HECHT offers individual modular
systems for wide-ranging and flexible
applications.
