Sugar and food industry

Precoat filtration of molasses

Precoat filtration of molasses

Molasses is the residual sugar syrup that can no longer crystallize, remaining after several stages of crystallization and centrifugation in the production of sugar from sugar beets or sugar cane.

Molasses still contains approximately 50–60% residual sugar, as well as other substances that prevent further crystallization.

To optimize yield, the molasses is separated into its sugar and non-sugar components using chromatography columns. This requires efficient removal of the undissolved solids.

This process is carried out year-round, regardless of the seasonality of the raw materials (sugar beets or sugar cane).

Blocking of chromatography.

Chromatography columns are high-quality pieces of equipment that are highly susceptible to clogging by solids. To prevent this, pre-coating filters that use filter aids are often used.

However, traditional systems such as plate filters or conventional cartridge pre-coating filters are often prone to leaks and/or solid-particle breakthrough, which in turn cause the chromatography columns to become blocked.

Reliable design for a reliable barrier.

The use of a patented candle filter design tailored to the sugar industry can increase process reliability and prevent breakthroughs.

At the same time, using such a system enables dry discharge, which increases yield and eliminates the need for additional slurry-processing equipment.
