The falling film evaporator with multi-effects designed by RITEK has excellent reliability and gentleness in product treatment. As the plant is working under vacuum conditions, the boiling temperatures are low and the stress of the product is reduced to minimum. The use of several effects reduces the steam consumption. And the short holding time is good for the heat- sensitive product’s color.
The whole plant is CIP-able. Under normal running conditions, all parts in contact with the product are cleanable without dismantling any parts of the plant.
Aroma recover system can recover the volatile aromatic substances during the evaporation process with a separate aroma column via condensation and distillation from evaporated product vapours and stored as aroma concentrated.
It is possible to integrate the juice pasteurizes with evaporator.
RITEK utilizes a series of multiple effect evaporators for fruit puree and tomato paste with forced circulation in tube nest heater in all the effects. Each effect basically includes: tube-nest, liquid vapor separation chamber and circulation pump. The pump pushes the product internally to guarantee that the heat exchange is always hot and minimizes the risk of burning, untill the brix value in each stage reach the requested by the next effect.
The evaporator operates under vacuum, which is maintained by a condenser connected to the evaporator’s last effect and to vacuum pump, in order to lower the boiling point of the concentrate and preserve the organoleptic properties. The full washing cycle CIP and PRODUCTION of the evaporators is managed through PLC.
