Scrapped Surface / Thin Film Evaporator

Scrapped Surface/Thin Film Evaporator 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.

• Tomato Paste
• Honey
• Solvent Recovery
• Milk concentrate (Khoa)
• Jam/Jelly.

The vapour is compressed to higher condensation pressure by means of either Thermal Vapour Recompressor (TVR) or Mechanical Vapour Recompressor (MVR), which results in steam economy. In TVR portion of vapour discharged from one effect is sucked and compressed using motive steam and the resulting mixture is used as a heating medium to bring down the specific steam consumption. In MVR the vapour is recompressed by using two stage compressor with mechanical seals. A typical five effect plant with TVR over three effect has a sp. Steam consumption of 0.12. & a seven effect plant with TVR having vapour suction from 4th effect has a specific steam consumption of 0.09.

SSP is capable of not only designing new evaporators but also enhancing the capacity of the existing ones. This results in improved operating conditions, increased capacity, lower specific steam consumption and saving in capital investment as well as operating cost. The capacity is enhanced by adding effects, thermo-compressors, etc. as the case may be.
