Heat-Transfer Needs in Sugar Процессes
In beet and cane sugar factories, теплообменники and испарительs are critical equipment that directly affect energy consumption. Different температура profiles, viscosities and загрязнение levels are assessed along the процесс line.

Процесс Points and Equipment Matching
Recommended heat-transfer equipment for typical sugar-factory процесс steps:
| Процесс step | Heat-transfer duty | Рекомендуемое оборудование |
|---|---|---|
| Diffusion / slicing | Juice heating, процесс-water heat recovery | Разборный пластинчатый теплообменник |
| Carbonatation / liming | Condensate and процесс-water heating | Разборный пластинчатый теплообменник |
| Evaporation (multi-effect) | Juice concentration, vapour generation | Испаритель |
| Crystallization | Massecuite cooling / heating control | Разборный пластинчатый теплообменник |
| Ethanol plant | Distillation preheating, condensate recovery | Разборный пластинчатый теплообменник / испаритель |
For material selection on juice and condensate lines, AISI 316 stainless steel is typical; in aggressive environments titanium or specialty-alloy plates are assessed. Gasket material is determined as EPDM, NBR or Viton according to процесс температура.

Часто задаваемые вопросы
Which теплообменник types are used in a sugar plant?
Juice heating, condensate and general процесс circuits typically use gasketed plate теплообменники; evaporation and concentration lines use испарительs. The Tanpera engineering team recommends the best configuration from fluid viscosity, загрязнение and давление class.
Is there an equipment difference between beet and cane процессes?
The core heat-transfer principles are similar; cane процессes often see higher температураs and different juice viscosity profiles. Расчёт is done separately from the проект data.
How is an испаритель selected for evaporation circuits?
Effect count, steam давление, juice concentration and target steam economy are the core inputs. Tanpera TES-series испарительs are sized to the проект specification.
How often is plate очистка required in sugar процессes?
Scale and organic deposits reduce plate производительность. Depending on the juice line, CIP or mechanical очистка every 6–12 months should be assessed. Rising перепад давления is an early signal that очистка is needed.
Which data are required for расчёт?
Flow rate, inlet–outlet температураs, fluid properties (viscosity, density), design давление, загрязнение profile and existing plant connection details form the minimum input set.
