Grain Distillery Plant
Plant engineering and equipment for grain-based alcohol production. ATTOMO develops the scope around the specified grain, product grade and co-product strategy.
Process and equipment approach
Grain preparation is followed by starch conversion to fermentable sugars, fermentation, distillation and product finishing. Grain selection and composition influence equipment duties. Stillage separation, evaporation and DDGS drying should be evaluated alongside the main alcohol plant.
Applications and product requirements
Grain-based plants use starch-bearing feedstocks to produce an alcohol-containing fermented stream. Grain type, starch, moisture, fibre and contaminants affect preparation and fermentation. Fuel ethanol, neutral alcohol and characterful grain spirits have different quality objectives; the project must identify the intended product.
Equipment and operating approach
The process can include grain cleaning and milling, slurry preparation, starch conversion, fermentation, distillation and product finishing. The chosen process determines solids handling before and after distillation. In a dry-grind co-product scheme, stillage separation, concentration and drying can produce a distillers-grains stream, subject to its feed-use specification.

Materials and configuration
Milling and solids-handling interfaces, fermenters, columns, exchangers and product receivers should be defined as a connected package. Stainless-steel grade, abrasion exposure and cleanability vary by section. Multi-grain operation needs an agreed feed range and operating plan; it is not established merely by choosing a grain plant.
Utilities and operation
Heating, fermentation cooling, process water and power must be balanced with the co-product section. Specify enzyme and process-chemical responsibilities, cooling design conditions, operating days and residual-stream handling. Dried co-product moisture and feed quality need their own acceptance criteria.

Frequently asked questions
Can the same plant process maize and rice?
A multi-feed design requires an assessment of each feedstock and the intended operating cases. Interchangeability should be confirmed during engineering.
Does grain processing automatically produce rum or brandy?
No. Those product names have different raw-material and production requirements. The intended spirit and applicable product rules must guide the process.
What grain analysis is needed for an enquiry?
Provide the grain type, moisture, starch content, relevant contaminants and expected variability. Include the intended operating schedule and requirements for grain handling and co-product management.
Is a DDGS dryer mandatory?
No. Co-product handling depends on the selected process, market and moisture specification. Wet-product sale and drying have different storage, logistics and utility implications.
What capacity basis should be used?
State grain throughput, operating hours, starch and moisture basis, and required alcohol output at a defined strength. Product output cannot be derived from wet-feed tonnes alone.
