I. Principle of the Co-current Flow Method in Multi-effect Vacuum Concentration Equipment
The co-current flow method in multi‑effect vacuum concentration equipment employs a series of evaporators, with the feed liquid sprayed into the heating tubes of the first effect. Subsequent effects operate at progressively lower vacuum levels, gradually reducing the water content and concentrating the material. The principle of the co‑current flow process is to introduce the feed from an effect operating at low vacuum into an effect operating at higher vacuum, thereby increasing the evaporation driving force in each stage and enhancing the overall efficiency of the evaporation process.
II. Characteristics of the Co-current Flow Method in Multi-effect Vacuum Concentration Equipment
1. High concentration efficiency
The multi-effect vacuum concentration equipment employs a co-current process. Compared with the conventional counter-current process, it operates at higher and lower evaporation temperatures, enabling faster evaporation and more thorough concentration, thereby enhancing overall concentration efficiency.
2. Low production costs
The multi-effect vacuum concentration equipment employs a co-current process, which boosts production capacity while reducing energy and raw material consumption, thereby lowering production costs.
3. Wide range of applicability
The co-current flow method of multi-effect vacuum concentration equipment can be applied to a wide range of concentration processes, including those in the juice, dairy, beverage, and chemical industries, and thus holds significant practical value.
4. Easy to operate
The multi-effect vacuum concentration equipment is equipped with a computer‑based automatic control system, enabling automated and intelligent operation, reducing manual intervention, and ensuring more stable and convenient operation.
5. Environmental Protection and Energy Conservation
The co-current flow multi-effect vacuum concentration system employs vacuum evaporation technology, which is environmentally friendly. Moreover, thanks to its high energy efficiency, it consumes relatively little energy, delivering significant energy-saving and environmental benefits.
