Dehydration process of sugar beet pulp

Schema Bettrave eng


From sugar beet to dehydrated sugar beet pulp

The dehydrated pulp comes from sugar beet. Dehydrated pulp consists of cell walls from the root of the beet after the sugar has been extracted.

It's a feed rich in digestible cellulose, perfectly suitable for ruminant feed.

1- Harvest and washing

The harvested beets go through powerful washers.

Once grit has been removed and the roots cleaned and washed, they are chopped into fine slices or schredded.

Obtaining overpressed pulp

These schredded sugar beet from which the sugar has been extracted by a diffusion principle (running hot water at 75°C), are then called wet pulp or fresh pulp and contain 90% humidity.

Passage through a first series of presses transform it into overpressed pulp (72% humidity).

2- Dehydration

Routed to the dehydration workshop, this pulp is dried in a rotary drum dryer.

With a current of hot air (600 to 800°C at the dryer entrance), it is reduced to 12% humidity.


3- Manufacture of pellets

This dried but not agglomerated pulp then goes into presses to be granulated into 6 or 8 mm pellets.

4- Elevation

The dehydrated sugar beet pulp is sent to our silos where it is homogenised, stored and formulated to obtain our commercial specialities.

Used to manage the variability of the qualities received (cuts and factory productions)


Consists of mixing the different qualities of alfalfa received to obtain homogeneous batches.


The homogenised batches are checked, analysed and identified, then stored in dedicated cells.


Formulation, by mixing different homogenised batches (of identified, listed qualities), leads to the manufacture of our different commercial specialities, which will be guaranteed by contract.
