Multi-effect system TC-MES-DDGS
Designed for concentrate stillage (fermented liquid after the distillation process) in order to increase the dry solids content before drying in the production of DDGS at bioethanol plants.
Structural features
Optimization of the evaporation process through the use of a four-body evaporator (EV) operating under vacuum with sequential utilization of secondary steam;
Use of falling-film and forced-circulation type evaporators for uniform product heating;
Possibility of integrating a steam-jet compressor to enhance energy efficiency;
Efficient system for removal of non-condensable gases and condensate from steam chambers;
Modular design that simplifies transportation, installation, and maintenance;
Complete thermal insulation of bodies to minimize energy losses.
Quality
Stable product concentration at the outlet (35–40% dry solids) ensured by precise control of temperature and hydraulic regimes;
Preservation of protein nutritional properties due to operation at reduced temperatures;
Uniform evaporation without scale formation or product overheating.
Economy
Low steam consumption — 0.25–0.3 t of heating steam per 1 t of evaporated water from the EV bodies; Possibility of utilizing heat from the dryer;
Reduction of energy consumption and operating costs compared to traditional systems;
Decreased load on drying equipment due to pre-concentration of stillage.
Reliability
Main components made of stainless steel AISI 304/316 resistant to corrosion and organic acids;
High operational reliability during long production cycles without cleaning;
Absence of stagnant zones in heat exchange sections;
Easy maintenance access through inspection windows and manholes.
Automation
Fully automated process control — monitoring of temperature, level, pressure, and dry solids concentration;
Instant response system to parameter changes ensuring stable product quality;
Integration with the plant’s central process control system (PCS);
Remote monitoring capability and storage of technological data archives.
