Industrial Evaporators

Falling Film Evaporator
Use of falling film evaporator with multiple effects ensures high heat transfer efficiency and is ideal for concentration of heat sensitive products, with low scaling tendency. Multi-effect falling film evaporators with TVR as well as MVR are available.

• All heat sensitive liquids.
• Milk
• Malt Extract
• Amine Acids
• Fruit Juices

Rising Film Evaporator
In a Rising Film Evaporator liquid feed enters from the bottom of steam heated tubes. The parallel movement of liquid and vapour along tube surface imparts effective water evaporation from the liquid feed. This type of evaporator is ideal for liquids which attain high viscosity or have fouling tendency.

Forced Circulation Evaporator
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
• Salt Crystallisation
• Effluent where crystallisation takes place

Scraped Surface/Thin Film Evaporator
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 Cane
• Milk

Combination Evaporator
For products which attain high viscosity during the concentration process, Combination Evaporators such as Falling Film followed by Rising Film, Scrapped Surface etc. are used.

• Effluents
• Chemicals
• Products Where meltability is a problem
