Frequently Asked Questions

DDGS (Dried Distillers Grain with Solubles) – what is it and what is it used for?

The distillation residue after ethanol distillation is a valuable source of nutrients that can be used in pig feeding. In this direction, we are developing distillery systems in combination with a residue treatment station in which we use devices such as evaporators. These serve to compact the thin effluent, which is one of the fractions of the centrifuged residue.
Our proposed technological arrangement of the evaporation station enables high compression of the medium with comparatively low energy consumption. The feedstock for the evaporation station connected to the distillery is the thin effluent and the main product is a compacted concentrate. The condensate steam is completely returned to the technological heating system. The system is fully automated and features automatic start and stop, resulting in relatively low operating costs. The liquid compression process is carried out continuously.
Compared to devices with periodic operation, continuously operating devices are thermally more economical, as there are no losses due to the periodic consumption of heat for heating and starting the device. We use evaporator batteries in which the evaporating solution gradually flows through several individual devices. In each subsequent evaporation, the concentration of the solution is higher than in the previous one.

What equipment is used to produce Distillers Dried Grain with Solubles (DDGS) after ethanol distillation?

The production line associated with the distillery for the production of DDGS (Dried Distillers Grain with Solubles), used as animal feed, requires the use of drying equipment in which the desiccant, after absorbing moisture, is artificially released into the atmosphere using fans, exhaust pipes and other devices is derived. In most cases, hot air is used for artificial drying. After distillation, the distillation residue can be used as animal feed. The spent grain obtained through the centrifuge and the syrup from the evaporators are fed into a steam-heated drying chamber. The dried material is moved from the inlet to the outlet using blades. The evaporated water is removed by a fan, while the condensate is fed into the boiler room via the condenser. A cyclone is installed between the dryer and the fan, which serves to separate entrained particles. The final product after the drying process is DDGS with low moisture content, which allows for easy storage and use as animal feed.

What advantages arise from combined heat and power between a distillery and a biogas plant?

Ethanol production requires high energy expenditure, which is associated with high production costs. To reduce this, there is the possibility of cogeneration of heat and power between a distillery and a biogas plant. The distillery can supply raw materials in the form of distillation residues for biogas production, which is a waste product from ethanol production. In return, the biogas plant can supply the distillery with thermal energy or electrical energy. This technology facilitates the profitability of both plants.
