Across Ukraine, grain producers are accelerating the switch from conventional gas- or grid-powered dryers to units that run on alternative fuels—primarily wood chips, sunflower husks, straw pellets, and other agricultural biomass. The driver is simple: lower and more predictable operating costs during autumn drying peaks, plus resilience against grid constraints and price spikes.
What’s changing on farms
-
Fuel mix. Modern burners are being fitted to existing dryers to accept biomass or multi-fuel (biomass/LPG/diesel) inputs. Many sites keep a dual-fuel setup to hedge risks.
-
Cost control. Biomass prices are often contracted locally and track agri-residue supply, delivering materially lower UAH/ton of evaporated water versus natural gas in peak months.
-
Throughput & quality. Current-generation heat generators provide stable inlet temperatures, enabling gentle drying curves that preserve test weight and reduce cracking.
-
Power resilience. Sites add PTO-driven or diesel generators for controls and fans, letting dryers run during outages; thermal energy comes from biomass combustion.
Typical upgrade path
-
Audit the dryer (capacity, air volume, temperature ranges).
-
Install a compatible biomass heat generator with cyclones and spark arrestors.
-
Add fuel handling (chip bunker, screw feeders, safety interlocks).
-
Tune drying programs for different grains and target moistures.
Economics in brief
-
Capex is recouped through fuel savings and fewer stoppages in wet seasons.
-
Locally sourced residues (husks, chips, straw pellets) reduce logistics and FX exposure.
-
Carbon intensity drops versus fossil fuels, supporting ESG goals and export narratives.
Risks & mitigations
-
Moisture variability of biomass: solved by covered storage and screening.
-
Ash and particulates: managed with multicyclones/filters and proper maintenance.
-
Compliance & safety: certified burners, flame-control, and fire-watch procedures around bunkers and ducts.
Who benefits
-
Medium and large grain farms drying corn, wheat, and barley at scale.
-
Cooperatives that centralize drying services for member farms.
-
Processors (e.g., feed and oilseed plants) seeking energy cost stability.
Bottom line for investors and operators
Alternative-fuel dryers convert farm residues into reliable heat, cutting drying costs, increasing uptime, and improving post-harvest quality. With modular burners and dual-fuel flexibility, upgrades can be staged with limited downtime—making this one of the fastest-payback efficiency projects in Ukraine’s agriculture.
