SMOOTHER PROCESSING

In the production of fish for human consumption, as well as in the industrial production of fish meal, there is an abundance
of by-products which can be re-defined as
valuable resources with the use of HILLER
decanters.

In industrial fish meal production the quality of the raw material, control of the cooker (temperature, retention time), and the
quality of the press water are showing a
significant element of feed-back on the entire process.

Some examples are the direct recovery of
protein from pumping water, fish meal and
oil production from off-cuts, frames and
viscera, and the on-board processing of
whole by-catch.

With the use of HILLER decanter technology in lieu of the screw press this vicious
cycle is eliminated, allowing smooth processing and stable processing with all raw
material qualities.

IMPROVED QUALITY

Aside of control of process temperature
and retention time as generally important
factors for the quality of fish meal and fish
oil, efficient oil removal from the protein is
required for the production of top quality
fish meal, as is minimal contact time between water and oil for top quality fish oil.
HILLER decanters are offering unique advantages here over the conventionally used
technologies, in conjunction with increased
flexibility and robustness of the process.
