Crossflow

The CROSSFLOW® cooker is suitable for all sugar-glucose syrup mixtures and can be used as a pre-cooker and ready-made cooker. This cooker has now almost completely replaced the traditional snake cooker, as it has undisputed advantages.

The size of the cooker varies from 8 - 4,000 kg / h, whereby the space advantages compared to snake cookers or other systems are considerable, especially with large throughputs.

The CROSSFLOW® cooker is a tube bundle heat exchanger in which the product is fed in countercurrent to the steam. Special deflection plates on the product side enable a defined, dead space-free flow through the product. Due to the very good heat transfer properties, it is possible to work with a relatively low vapor pressure, since the temperature differences required for heat transfer are comparatively small.

It is also possible to operate the CROSSFLOW® cooker as a pressure dissolver. Here, with an initial dry matter of 90 DM, the sugar crystals can be loosened gently and in a way that saves energy.

The advantages of the CROSSFLOW® cooker compared to conventional cooking systems are:

• space-saving installation,
• stable, very precise cooking temperature (+ / 0.1 K),
• even discharge into the vapor separation chamber,
• high product quality,
• short residence times,
• gentle process,
• optimal start and stop behavior,
• short response times,
• fully automated start-up, shutdown and cleaning process possible.
