FORCED CIRCUL. EVAPORATOR

The forced circulation evaporator uses a pump to circulate liquid through steam-jacketed tubes at high pressure created to prevent boiling.

WORKING PRINCIPLE

The liquid is circulated through the calandria by means of a circulation pump, where it is superheated at an elevated pressure, higher than its normal boiling pressure. By entering the separator, the pressure in the liquid is rapidly reduced, resulting in some of the liquid being flashed or rapidly boiled off.

MAIN DESIGN FEATURES

Concentrate on quality and yield of high-viscosity, heat-sensitive products at low temperature and high heat transfer efficiency.


  • Preserves the quality of highly viscous, heat-sensitive products

  • Boiling/evaporation does not take place on the heating surfaces but in the separator. 

  • Fouling due to incrustation and precipitation in the calandria is therefore minimized.

  • More uptime due to reliable, robust, self-cleaning construction

  • Versatile, modular design makes it easy to process various products with similar physical properties and adapt capacity as needed

  • High yields due to long running times – ideal for uninterrupted processing of fresh produce during harvest season

PROPERLY DESIGNED EVAPORATOR
PROPERLY DESIGNED EVAPORATOR

A properly designed evaporator must, at a minimum:


  • Be designed to effectively transfer heat at a high rate with minimum surface area to be cost-effective for installation,operations and maintenance

  • Effectively separate the vapor from the liquid concentrate

  • Meet the conditions required by the product being processed

  • Produce a product that meets the required quality

  • Be energy efficient, where possible making effective use of steam with multiple-effect evaporation or vapor recompression

  • Minimize fouling of heat transfer surfaces

  • Be constructed of materials that are adequate to minimize corrosion

APPLICATIONS
  •  Designed for products with high levels of solid material content and/or high viscosity.

  •  Tomato juice concentrate.

  •  Fruit concentrate.

  •  Tropical fruit concentrate (mango, papaya, etc.).

  •  Red berries concentrate (strawberries, cranberries, etc.).

  •  Useful in all food industry processes where extraction of some water from raw materials is necessary at the same time maintain ing the product’s organoleptic properties.
