FERMENTER

To optimize the growth rate of the product in a fermenter, you must control the concentration of the feed; too low a concentration and the microbes starve, too high a concentration and they burst.

Production Challenge:

In a batch process, a prism wash cannot be done in situ (or within the fermenting tank) since wash liquid would accumulate in the solution.

 Solution: 

An Exner probe housing is used, where the probe tip is withdrawn into a separate chamber for prism washing. This preserves the process concentration without adding any contaminants.

Prism wash is required in a fermenter. 

CRYSTALLIZER

In a crystallizer, supersaturation is driving the crystal production. Too low supersaturation slows down the growth, too high supersaturation makes the crystals stick together forming conglomerates.

Supersaturation is a function of concentration and temperature. By utilizing ThinProbe you get a fast, accurate measurement of both. Moreover, both temperature and concentration are measured at the exact same point, which increases the accuracy of the supersaturation determination.

IN-LINE FEEDBACK CONTROL

Supersaturation is a function of concentration and temperature. By utilizing ThinProbe you get a fast, accurate measurement of both. Moreover, both temperature and concentration are measured at the exact same point, which increases the accuracy of the supersaturation determination.
