Vacuum evaporator Evapor

centrifugalthin-filmprocess

Product overview
Evapor is NTE Process’ centrifugal-flow thin-film vacuum evaporator (powered by Okawara MFG Ltd), engineered for concentration of heat-sensitive, viscous and high-value products. The unit uses a rotating cone to form an ultra-thin film (> 0.1 mm), preventing foam and minimising product residence time on the heated surface. Evaporation can be performed at reduced temperature (up to 35°C) to limit thermal impact and preserve active compounds.

Advantages

• Low-temperature evaporation with extremely short residence time, suitable for heat-sensitive products
• High overall heat transfer coefficient enabling high evaporation capacity per unit
• Foam formation minimised by centrifugal action
• Reduced product deterioration and superior concentrate quality (higher soluble solids and viscosity) compared with plate or tubular evaporators
• Evaporation surface can be monitored during operation
• Hygienic design with easy-to-clean evaporation surface; CIP version available
• Compact, skid-mounted design for straightforward installation

Components included
Evapor is supplied as a compact unit with feed pump, discharge pump, distillate pump, vacuum pumps, condenser, control panel and other necessary auxiliaries mounted on a common base, ready for integration into production lines.

Applications

• Enzymes and antibiotics
• Protein solutions and fermentation broths
• Chinese herbal extracts
• Various extracts (meat, fish, mushroom, etc.)
• Flavourings and seasonings
• Tea and coffee
• Fruit and vegetable juices and extracts
• Oils and fats
• Vitamins
• Synthetic resin

Suitable industries
Food, pharmaceutical, chemical, biochemical and other sectors where conventional evaporators face limitations.
