Evaporators

Falling Film Evaporator is a shell and tube type heat-exchanger, widely used in industries for evaporating heat sensitive liquids such as juices. In this evaporator, the hold up and residence time is short and thus, the liquid does not get overheated.
Operation:

• The feed entering from tubes flows downwards due to gravity
• While the heat is provided through a medium in order to create a high heat-transfer coefficient
• The feed then gets distributed resulting in formation of a thin film
• Usp:
  • High efficiency
  • Maximum heat transfer in the least time
  • Feed transfer is free of clump-formation
  • Short hold up and residence time
  • No overheating of liquid
  • Uniform wetting
  • Unique distributor head design ensures no crusting
  • Robust construction for enduring performance
  • Customization facility for meeting the feed-properties and characteristic behavior in process
  • Application:
    • Food and beverage industry
    • Pharmaceutical industry
    • Paper industry
    • Dairy industry

Incorporated with advanced technology, this Forced Circulation Evaporator is designed as a tubular heat exchanger that concentrates the feed. It is specifically designed for handling corrosive viscous solutions. This system follows a very simple operation in which an external mechanical agent is used to pump certain portion of concentrate at the point where feed enters the evaporator.
Usp:

• Highly suitable for crystalline feeds or those containing solids
• Ensures high concentrate-to-feed ratio
• Easy to maintain systems

• Zero-scaling
• Increased heat transfer rate
• Can handle salting and fouling liquids
• Applcation:
• Effluent treatment
• Chemical industry

Hybrid Evaporators are specially designed for applications where combination of stages is required. In this system, steam is normally the heating media, however, thermic fluid and other sources can be also used.
Usp:

• No scaling and foul odor
• Robust construction

• Easy installation and operation
• Excellent heat transfer rate
• Application:
  • Dairy industry
  • Herbal extract industry
  • Beverage industry
  • Waste water treatment plant

This Agitated Thin Film Evaporator is specially designed for handling high sensitivity and viscous products. This is designed using highly robust materials to ensure high end performance even in hazardous applications.
Operation:

• The liquid fed into the chamber is distributed as a thin film on the heated wall before starting the heat transfer process
• A rotor encapsulated inside the heating shell wipes the fluid film from the walls
• An entrainment separator is used to clean the vapors generated due to concurrent heating flow in the evaporator
• Usp:
  • Customized design is capable of handling different products under varying operating conditions
  • Ensures lower product wastage
  • Heat transfer achieved through turbulence
  • Processing of entire mass, resulting in high yields
  • 30% to 80% concentration is possible in a single pass
  • Low residence time
  • Suitable for heat sensitive and viscous products
  • No requirement of product re- circulation
  • Less risk of possible product degradation
  • No scale formation on the heat transfer surface
  • Excellent turn down capability
  • Low product hold up
  • Ideal for hazaroud applications
  • Application:
    • Paint industry
    • Organic chemical industry
    • Pharmaceutical industry
    • Tea industry
    • Citrus manufacturing industry
