To achieve year-round cultivation, farmers can implement crop rotation and use season-extending techniques like greenhouses and polytunnels. Choosing varieties that are suited to different growing seasons also helps maintain continuous production. In warmer climates, beetroot can be grown during cooler months, while in temperate regions, successive planting ensures a continuous supply.
Technology for Converting Beetroot to Ethanol
The process of converting beetroot to ethanol involves several key steps:
1. Harvesting and Processing:
Beets are harvested and cleaned to remove soil and debris.
The cleaned beets are then sliced into thin strips to facilitate sugar extraction.
2. Extraction:
The sliced beets are subjected to a diffusion process where hot water extracts the sugars.
3. Fermentation:
The sugar rich juice is fermented using yeast, which converts the sugars into ethanol and carbon dioxide.
4. Distillation:
The fermented mixture is distilled to separate ethanol from the residual water and other by products.
5. Purification:
The ethanol is further purified to achieve the desired concentration, typically 99% or higher for fuel grade ethanol.
