Highly flexible moulding/packaging line,
new machine series
Chr. Bock & Sohn, a long-established
supplier of moulding
and packaging lines for
food fats from Norderstedt,
Germany, reports growing
sales of its machines to butter manufacturers.
Numerous suppliers to the
bakeing industry are turning to recombined
butter, as it offers technological
advantages in further processing.
For Uelzena, a completely new machine
has been developed that can
form and package textured butter in
sheets and blocks. The BFW 15 (the
designation stands for Bock Flexible
Wrapper for a product weight of up to
15 kg) has already been sold to other
butterfat producers since the pilot project
at Uelzena. Its output is up to 8
t/h. The BFW 15 achieves its flexibility
through the consistent use of servo
drives. Packages from 2 to 15 kg can
be produced. Virtually all products that
come from a scrape heat exchanger
can be processed. "The development
of the BFW15 is based on a patent that
we took over from Gerstenberg & Agger
in 2007," explains sales manager
Gerd Ketterer. "We were able to keep
the machine very small in terms of
floor space; this benefits the production
plants just as much as the modern
control system, which makes work
much easier for the plant operator with
its contemporary design based on pictograms.

3000 series
There is also news from Chr. Bock &
Sohn regarding the further machine programme.
This year, a complete relaunch
is taking place, which finds its expression
in the 3000 series. Included in the revision
are the block packaging machines
DKS and SAB as well as the plate packaging
machine BPM. These are equipped
with new features, such as Siemens S7
1500 control or more sensors in the dosing
system, so that temperature and
flow rate can be precisely determined
and critical conditions detected. In addition,
the machines can regulate their
own speed, with the rework rate as an
additional parameter. Like the BFW 15,
the new 3000 series features the new
HMI. Externally, the 3000 series also differs
from its predecessors by the particularly
solid constructed frames and the
so-called "Mood Line", an LED band that
runs around the top of the machine and
visualises the operating status.
However, the classic design with cam
discs is retained. "It is possible to automate
machines too much," says Sales
Manager Heiko Berndt. "This always requires
appropriately qualified personnel
on the part of the user, and servo technology
is not so durable that it will last
the average service life of our machines
of 30 to 40 years."
According to Ketterer, the market for
butter blocks in the 2 to 10 kg range is
becoming increasingly interesting, espe-
