The best enzymes for viscosity reduction in distilling

Even with good liquefaction and saccharification, you can end up with mashes that are too viscous. It can cause problems in production and reduce the longevity of the machinery. 

This is especially a problem with “small grains” such as rye, wheat, barley and triticale. The cause is water-binding non-starch polysaccharides (NSPs). In "small grains" these are challenging to extract and solubilize. Viscosity-reducing enzymes break down NSPs so you can run your process at a high DS level and get more flexibility in your choice of raw materials.

To find out all there is to know about how enzymes can benefit your distilling process check out the topics below.

Are all enzymes for viscosity reduction in distilling the same? 

No, the best is optimized for distilling and have the following abilities:

  • Reduce viscosity: Viscosity reduction is one of the most important processes in ethanol production.

  • High dry solids (DS): With a High Dry Solids (DS) mix you can increase production and decrease fouling, cleaning and wear of equipment, improved mash flow and higher centrifuge and evaporator efficiency. The result is a lower energy and water spend and more cost-effective operations.

  • Raw material flexibility: Can be used for many different raw materials, especially “small grains” such as rye, wheat, barley, and triticale.
  • Wide-pH range tolerance: Allows you to get more out of your mash and reduces the need to adjust the pH (less work, problems, cost and chemicals)

  • Lower viscosity: You want to have a high level of dry solids and at the same time keep a production without problems like channelling the mash through the stirred tanks and reduce ware of pumps, heat exchangers, jet cookers and agitation all run better at low viscosity.

  • More efficient conversion: You get 0,5-5% more alcohol, use 20% less CO2 with more efficient enzymes and it all adds up to less cost for the same output.

  • Thermostable: Quality enzymes still perform well at high temperatures (even at 95°C).

  • Infection: Low risk of infection because of low Ph and high temperature tolerance.

  • Faster: Work up to double as fast.

  • Better: Convert up to double as many starts.

  • Organoleptic: Increased organoleptic properties with best-in-class enzymes. 

  • Equipment: Less wear and investment in equipment.

You get less problems and use less time in the production, need less equipment, save energy and money, get a bigger output in higher quality with our innovative solutions.
