Continuous Solid-State Ethanol Separation Device

The patent implements continuous solid-state fermentation by replacing traditional intermittent batch processes with a continuous flow system. Fermentation materials continuously move through the reactor while maintaining steady-state operation, eliminating idle times between batches and ensuring constant ethanol production. This continuous operation significantly improves production efficiency and prevents alcohol volatility by maintaining consistent fermentation conditions.

The patent introduces dynamic elements to handle the intertwining crushed straw material. A rotating distributor with radial distributing plates continuously rotates to break up material clumps and distribute them uniformly. Additionally, a stirring device with rotating blades continuously agitates the fermentation material, preventing entanglement and ensuring smooth continuous flow through the reactor while maintaining the simplicity of using crushed straw.

The patent introduces an indirect heating system using a heat exchange medium (thermal oil or molten salt) as an intermediary between the heat source and fermentation material. This intermediary fluid circulates through heating channels in the reactor wall, providing efficient heat transfer to the material without direct contact with the heating element. This approach maintains high heat transfer efficiency while reducing energy consumption and producing drier residues suitable for fuel use.

The patent implements a feedback control system with sensors that continuously monitor material flow rate, temperature, and pressure parameters throughout the continuous fermentation process. These sensors provide real-time data to a control system that adjusts operating parameters to maintain optimal conditions. The feedback mechanism enables precise monitoring of material movement despite the continuous flow nature, ensuring stable and efficient production.
