Centribone
A continuous wet rendering method for processing meat by-products
Alfa Laval Centribone plants provide the most versatile and
efficient way to process meat by-products. The continuous wet
rendering process can handle any raw material, from purely
fatty tissues to the best gelatin bones. The low-temperature
process is a totally closed system, especially suitable for
processing edible products. With Centribone’s state-of-the-art
processing, you can now move into more profitable segments
in the market of end products.
High quality end products
To obtain the highest quality end products, the temperatures of
fats, proteins and collagens must be kept as low as possible
while processing.
Centribone enables the production of high-quality fats, with
outstanding colour, and no increase in free fatty acids (FFA) or
peroxide value(s) and with very low moisture content. In the
processing of pet foods or edible proteins, Centribone retains
the highest possible nutritional values. The amino acid spectrum
is virtually unaffected. This is due to the optimized heating
programme – with the colour of the proteins and fats confirming
its value.
Centribone’s continuous processing makes it easy to maintain
uniform quality. Producers benefit in terms of ease of operation
– and customers appreciate the difference.
Flexible production planning
In reducing start-up and shutdown times, Centribone not only
makes production more flexible and more efficient, but also
allows more time in any production schedule. In a Centribone
plant, for example, processing different raw materials such as
fatty tissues and bone is possible in successive cycles, if
required. Whether you are a large-scale operator or a small
one, your productivity is improved.
Short-time melting process
The minced material fed to the inlet of the raw material heater
is led through the heater by a variable-speed conveyor. The
holding time in the heater can be as short as five minutes,
where the temperature is carefully controlled at 65–90°C
(150–195°F), depending on the raw materials used and the
end product desired. Rapid heating is achieved by injecting
live steam directly into the raw material. Fully automatic
control of the temperature profile can be obtained through
built-in temperature sensors, available as optional
instrumentation.
Low energy consumption
With Centribone, energy consumption is reduced by as much
as 30%, compared with dry rendering methods. This is
because the decanter and separator remove most of the
process water mechanically. And, unlike conventional
processes, Centribone becomes more economical to use as
the water content of the raw material increases.
Flexible throughputs and layouts
Centribone plants can process a variety of raw materials at
rated throughputs ranging from 3 to10 t/h. At higher throughputs,
flexible twin-lines are normally recommended.
Because of its logical, compact design, a Centribone plant
requires minimum space. It can be easily fitted into existing
buildings. In addition, it is easy to operate and maintain.
Automation
Full automation – ensuring optimum processing conditions at
all times – is a readily available option with Centribone. The
