Integrated Distillation & Filtration System for High-Purity Neutral Spirit & Premium Vodka
LENO TANK provides a complete, precision-engineered equipment solution for the industrial-scale production of high-purity neutral spirit and premium vodka. Our systems are designed to master the core challenge of vodka production: efficiently stripping away all congeners, flavors, and impurities from the fermented wash to achieve a clean, neutral base of exceptional purity (up to 96% ABV), which can then be polished and tailored to create a super-premium product.
Core Production Stages & LENO TANK Equipment Integration:
| Production Stage | Critical Process Requirement | Recommended LENO TANK Equipment | Key Value & Advantage |
|---|---|---|---|
| 1. Fermentation & Wash Preparation | Producing a consistent, high-yield fermented wash (beer) from grain, potato, or molasses. | Stainless Steel Fermenters, Temperature Control Systems, CIP | Hygienic Fermenters prevent bacterial contamination that creates off-flavors. Precise temperature control maximizes ethanol yield. CIP systems ensure cleaning between batches. |
| 2. Primary Stripping / Beer Distillation | Removing water and non-volatile solids, and concentrating the alcohol and congeners from the high-volume, low-ABV wash. | Stripping Column, Energy-Efficient Evaporators | A dedicated stripping column or multi-effect evaporator efficiently removes bulk water, reducing energy load on the primary distillation system and increasing throughput. |
| 3. High-Rectification / Neutral Spirit Production | The Most Critical Stage: Precisely separating ethanol from methanol, fusel oils, aldehydes, and esters through fractional distillation to achieve neutrality. | Multi-Column Continuous Distillation System, Hybrid Pot Still with Reflux Column | Multi-column systems are the industry standard for high-volume, high-purity spirit. They use linked columns (analyzer, rectifier) with precise temperature and reflux control to isolate pure ethanol vapor. Our Hybrid Pot Still with a tall reflux column is ideal for craft producers seeking a batch method with superior control over cuts. |
| 4. Filtration & Polishing (Vodka Specific) | Removing trace impurities and smoothing the spirit's mouthfeel after distillation. This defines premium vodka character. | Activated Carbon Filter Housings, Mechanical Filtration Systems | Activated Carbon Filtration is essential for adsorbing remaining trace congeners and achieving crystal clarity. Additional precision cartridge filtration (down to 0.5 micron) provides final polish and mouthfeel refinement. |
| 5. Blending, Dilution & Finishing | Reducing the high-proof spirit to bottling strength with ultra-pure water and ensuring perfect consistency. | High-Precision Blending Tanks, Deionized Water Systems, Bright Tanks | Automated blending tanks ensure accurate, repeatable dilution. Integration with a deionized or reverse osmosis water system is critical to prevent introducing flavors. Bright Tanks provide a holding vessel for final quality checks before bottling. |
| 6. Bottling Preparation | Ensuring the finished vodka is crystal clear and stable before packaging. | Final Polish Filters, Mobile CIP Carts | A final sterile membrane filter guarantees microbiological stability. Mobile CIP Carts maintain hygiene in all transfer lines and bottling equipment. |
Why Choose LENO TANK’s Vodka Production Solution?
Engineered for Purity & Efficiency: Our multi-column distillation systems are designed for maximum theoretical plate efficiency, delivering the highest possible purity and separation to create a truly neutral spirit base with minimal energy consumption per liter of alcohol.
Total Process Integration: We provide more than just a still. From fermentation management to final filtration and blending, our integrated approach ensures each stage is optimized for the next, guaranteeing final product quality and streamlining operations.
Scalable from Craft to Industrial: Whether you are a craft distillery focusing on small batches of ultra-premium vodka or a large-scale neutral spirit producer, LENO TANK offers scalable technology—from advanced hybrid pot stills to fully automated continuous distillation plants.
Hygiene & Material Integrity: All product-contact surfaces are AISI 304/316L Stainless Steel. This prevents flavor pickup and corrosion, ensuring the spirit’s neutrality is protected throughout the entire process, from fermentation to filtration.
