The liquid feed is pumped into the steam heated tubes at an entering velocity of 2-6 m/s from the bottom. The liquid is superheated as the static head is reduced during flow from the heater to the vapour separator and it flashes into a mixture of vapour and liquid. Liquid returns to the Pump inlet, where it is recirculated. Vapour leaves from the top of the effects. This type of evaporator is ideal for concentration of viscous liquids with high specific gravity or that tend to form scaling.

• Tamato Paste
• Mango Pulp
• Sodium Chloride
• Effluents where Crystallisation takes place
• Guava Pulp

Scrapped Surface / Thin Film Evaporators are designed for evaporation of highly viscous and sticky products, which cannot be otherwise evaporated. This type of evaporators have been specially designed to provide high degree of agitation, effecting heat transfer as well as scrapping the walls of the evaporator to prevent deposition and subsequent charring of the product.

• Honey
• Khoa
• High Concentration many products

This is type of evaporators are combinations of falling film, forced circulation & thin film evaporators. The application depands upon the nature of product its mitial and finalconeentration and crystallisation properties.
