The best enzymes for distilling

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

Adding enzymes in your ethanol distilling process can improve the result and reduce the number of problems. If you don’t use quality enzymes in your distillery you risk missing out on the following benefits:

  • Higher ethanol yield: The best enzymes for liquefaction and saccharification maximizes starch and dextrins conversion to sugars for yeast fermentation to ethanol. The result is higher ethanol yield, the reason is optimizing the whole production process and solving problems that might arrive.

  • Lower viscosity: You want to have a high level of dry solids and at the same time maintain a production without problems like channelling the mash through the stirred tanks and reduce ware on pumps, heat exchangers, jet cookers and agitation since they all run better at low viscosity. This is made possible with our best-in-class products. 

  • No-jet-cooking: No problem, with aggressive enzymes you still get hydrolysis and high viscosity reduction.

  • 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.

  • The Maillard reaction: With lower pH you lose less sugar to the Maillard reaction hence experience a higher alcohol output.

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

  • Reduce bacterial infection: Bacteria reproduces much faster than yeast and will consume sugar. By increasing the temperature and lowering pH you can inhibit bacterial reproduction. Whereas enzymes will work effectively.

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

  • Equipment: Less wear and investment in equipment.

  • Fast fermentation rates: Faster ethanol production early in fermentation means you get a higher production capacity from the same facility.

  • Effective on varying types and quality of raw materials: The best enzymes for liquefaction and saccharification have been successfully tested on a wide range of raw materials, in different conditions and have provided reliable top performance.

  • Wider pH range tolerance: Allows you to get more out of your mash and reduces the need to adjust the pH (less work, problems, cost, chemicals and wider pH range).

  • Foam: Reduce foam and the associated problems. Get full use from your equipment and reduce the usage of chemicals with our biological anti- foam agent solutions (enzyme).

Using high-quality enzymes means cost reduction from less energy used, less wear on machinery and a reduction in man hours used and qualifications needed to handle the production. The benefit is not only larger ethanol output, but also faster production and higher quality.

When you improve output and reduce cost at the same time, you become more profitable. Our customers say enzymes make the difference between operating in the red and doing very well.

How do enzymes make those benefits?

While enzymes solve many problems, it is still a craft to apply them in an optimal way. Therefore, unlocking all benefits from using enzymes come both from using the best products, experimenting, and getting advice from experts.

Enzymes for liquefaction

Optimized alpha amylase enzymes help cut the complex carbon structure into smaller pieces and thereby making it a liquid ready for further processing. Making it a liquid not only makes it easier to pump around and leaves less residuals, but also reduce the need for adding water and thereby reduce the energy need and procedure more output because the mash is more concentrated and is easier available for yeast.

Enzymes for saccharification

For your input, you want more ethanol. Enzymes for saccharification convert dextrins and oligosaccharides into sugars, to let the yeast develop as much alcohol as possible. Distillers have traditionally been heating up starch to decompose it into sugars. You can improve this process by adding optimized enzymes or heat less and still get more ethanol.

Enzymes for viscosity reduction

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. You can read about it in more detail here
