Complete falling film vacuum evaporator, previously used for infant
milk, consisting of 5 bi-thermal effect TVR Evaporator with a direct
steam injection (DSI) pasteurizer and an expansion chamber. Still
mounted in the Danone plant in France till end of March 2026. The
product feed rates in the installation can vary between 14 and 23 t/h
with a comparative temperature between 78 and 54°C from the 1st to
the 5th effect. The system is heated primarily by injecting steam into
the thermo-compressor. The preheating of the incoming product is
achieved via tubular heaters supplied by vapours drawn from the beams.
A direct steam injection pasteurizer and expansion chamber is provided
to pasteurize the product in a range of 118 to 133 °C., Line modified
in 2000 to replace the mixing condenser with a tubular condenser and
installing the heat treatment with direct steam injection., The
evaporator is used to concentrate 4 product categories:, - Lean
hydrolyzed products pasteurized at 125°C., - Lean or fat fermented
products pasteurized at 118°C., - Pre-organic products pasteurized at
118°C., - Compact products pasteurized at 133°C., Processing rates
used by the current dairy:, - Skim / whole milk - infeed flow 15.500
kg/h - evaporation 11.400 kg/h - outfeed flow 4.100 kg/h., - Skim /
whole milk - infeed flow 17.000 kg/h - evaporation 12.300 kg/h -
outfeed flow 4.700 kg/h., - Skim / whole milk - infeed flow 21.000
kg/h - evaporation 13.800 kg/h - outfeed flow 7.200 kg/h., - Cleaning:
flow 23.000 kg/h, Production times vary between 14,5 and 15 hours, and
monitoring is carried out on samples taken from the output of beams 3
and 5b for thermophilic bacteria. The pH of the concentrate is also
monitored. The results of the bacteriological monitoring can also be
used as criteria H6353732 for shortening processing times.,
Additional features:, - Dismantling possible from 01-04-2026 (line in
production till this date)., - Dismantling and loading in
containers/trucks will be taken care of by Hamburg Machinery and is
included in the price., - Big set of spare parts included (purchase
value EUR 90.000,-), list can be presented on request., - Software and
PLC program is excluded (integrated in the complete system of the
dairy of Danone)., Type of Machine: Evaporator, Stages: 5x Bi-thermal,
