• The feed gets distributed and thin film is formed
• Hold up and residence time is short hence liquid does not get overheated

In Falling film evaporators, feed solution forms a film in the evaporator tubes & gets evaporated. These are best suited for heat sensitive materials such as fruit juices. The hold up time is short & liquid doesn't get overheated. Falling film evaporators are not suitable for crystallizing liquids. They are not suitable for salting & severely scaling liquids or solutions.

• Useful for moderately heal sensitive product
• Compact and simple design
• Most suitable for corrosive liquids

In rising film feed solution forms a rising film in the tubes. These are unsuited to salting or severely scaling liquids. These evaporators are compact, simple in construction. They are suitable for corrosive liquids.

• Can handle salting, scaling and fouling liquids
• Best suitable for crystalline products, corrosive viscous solutions

Forced circulation evaporators can handle salting, scaling & fouling liquids. They are best suitable for crystalline products, corrosive & viscous solutions.
These evaporators have relatively high hold up or residence time thus not suitable for heat sensitive liquids.
They suffer frequently from plugging of tubes, salting in tubes & poor circulation.

• Reclusively less expensive
• Facilitate easy de-scaling
• Can be widely used in sugar industry.

Short tube evaporators are the oldest but still widely used. They are most widely used in Sugar Industry in evaporation of cane-sugar juice.
They are relatively inexpensive & easy de-scaling. This type is seldom used as a crystallizing evaporator. By installing a propeller, propeller calendria type evaporator can be used for crystalline products.
They suffer from mild scaling but can be cleaned mechanically.

We offer single effect or multi-effect evaporators according to product properties & /or clients requirement with or without thermal compression to lower temperatures & reduce residence time of product.
