Big and intelligent: the yeast separator

Yeast has Culture

Yeast – the unknown being. This used to be the case. Today, saccharomyces with

around 40 species and more than 500 types is probably the best-known and most

investigated micro-organism. There are virtually no limits to its use in the food,

pharmaceuticals, biotechnology and cosmetics industries. A yeast cell has a size of

only 5 –10 micrometers, but contains an unbelievable variety of valuable constitu-

ents. Westfalia Separator’s modern separation technology means that it is now pos-

sible for yeast cells to be broken down and processed.

Westfalia Separator VISCON®

The last few years have seen a great deal of progress being made in the field of

concentration centrifuging with nozzle separators. The development of the viscos-

ity-controlled nozzles (VISCON®) signalled the end of annoying adjustments to the

separators’ parameters in response to changes in the feed conditions, with the

result that the solids concentration in the discharge is now constant. The HF series

of nozzle separators represents state-of-the-art technology in the production of

baker’s yeast and yeast extract.

Discharge with Westfalia Separator

HydroStop

With the HydroStop system, Westfalia Separator has developed a discharge system

for molasses clarification that can be adjusted precisely and reproducibly to the spe-

cific solids concentration requirements of the process. This patented discharge sys-

tem enables the discharge process to be optimised extremely quickly. The Westfalia

Separator HydroStop system reduces the actual discharge time to less than 1/10 of a

second and also permits reproducible partial discharges.

GEA

Discharge with Metering Piston

In the newer HF generation of nozzle separators, the solids are discharged by means

of metering pistons. The basic idea of this control system is for metering devices to

supply an accurately metered quantity of opening water to the bowl during partial

ejections. Thus, precise discharge volumes can be achieved which can, in addition, be

adjusted flexibly from the outside. Therefore, if partial ejections are desired with par-

ticular products, these can be carried out efficiently and with minimum product losses

with the metering piston system.
