AB MG ASTRA has produced and
delivered yeast propagation unit
In June AB MG Astra produced and succesfully tested the yeast
propagation unit manufactured under the Ukrainian client order. The
specialists of AB MG Astra took participation in all phases of the
project management: designing technological scheme, preparing the
specification and conducting purchasing activities of required
equipment, projecting automatic control system (ACS), ACS assembly,
tanks and piping engineering, manufacturing and montage. The yeast
propagation in this unit is executed in the specially designated for
this purpose two tanks – the propagators, in which wort is beeng
circulated and injected with filtered and sterile air. The yeast
propagation unit is comprised of dry yeast intake tank,
sterilization tank, enzyme dosing unit and two propagators. All the
tanks and piping are fully higienic. Depending upon the yeast type,
the propagation rate during one cycle starts from initial 5 mln
yeast cells/ml and reaches up to 80-130 mln yeast cells/ ml. The
duration of one cycle – 48-70 hours. The wort in the propagation
unit designed by AB MG ASTRA is mixed in more effective way: not by
means of mixer, but by recirculiation of the wort. All the
technological process is thouroughly automatised. The automatic
control system contains controllers and sensors of the renowned
producers in this field - "NEGELE", "E&H","Siemens, the system is
managed by logical controller SIMATIC S7-300, which has been
programmed with STEP7 computer programme. The ACS is capable to
communicate with other modules of the manufacturing process, for
example CIP station, via speedy PROFIBUS-DP or Ethernet conections.
The system is equipped with complete process visualization (HMI)
tool on the basis of the WinCC programme.

Machinery plant "ASTRA" produced and
dispatched for the customer in Russia 8
pcs of beer fermentation tanks of 77 cubic meters
volume.

During 5 days
machinery plant „ASTRA“ AB loaded and sent to Russia 35 pressure
vessels for alcohol industry There were 18 railway platforms.
Diameter of sent vessels was in a range from 1m3 (yeast vessel) to 52m3 (cognac vessel). It is the
biggest shipment of vessels made in Alytus
during all machinery plant history.

On the 22nd of April 2009 in Machinery plant „ASTRA“ was opened new
workshop of stainless steel tanks production, which is worth about 4
mln. Eur. Equipment was brought from Italy, Germany, France,
Slovakia, Switzerland and USA. It is first time in Baltic States to
use such modern stainless steel automatic welding (PLASMA+TIG), wich
makes welding 10 times more effective compare to previous methods.
We are equiped by unique dimple jacket welding technology, wich
allows to reduce the cost of dimple jacket material 2 times. That
will influence prices, higher level of quality, shorter producing
process time and our company will be more competitive. Modern and
efficient machinery for grinding and planishing of spherical and
conical surfaces is also a big step forward. Today these
technologies allows to produce stainless steel tank, pressure
vessels and reactors for pharmaceutical, food, biofuel, nuclear,
chemical and other industries making all operations in one place.

In brand new stainless steel vessels production plant
of Machinery plant "ASTRA" is installed and already started up new
line for production of stainless steel vessels layouts. This new
line consist 4m large guillotine scissors, automatic welding
machine, automatic planisher and rolling machines. Also new machine
for automatic welding of dimple jacket is installed and successfully
started up. All new equipment is already in use and permits to enjoy
increased productivity and high quality of produced stainless steel
vessels.

Mounting works of new equipments are
going on in our new 3600 m2 workshop for stainless steel tanks. The
mounting works now is going for new welding equipments (Plasma+TIG)
that consist of a 4 m. seamer and in another new workshop in the
same building a vertical boom with turning table for circular and
vertical weldings also with Plasma+TIG. Some enhancement are being
made as well for
the existing TIG/MIG boom (adding oscilation, control and video
monitoring). New equipments will offer us capability to weld metal
sheets up to 15 mm without edge preparation in one pass. the same
line will consist of refurbished 4 m. Promecame geliotine, new
planisher (rolling and grinding of welds) near to the seamer. New
automatic grinding and polishing machine for dished heads, cylinders
and tanks. A new automatic TIG machine for manufacturing of cooling
dimple jackets. Stay tuned for more photos, detailed information and
estimation of the openning date.
