Evaporator Climbing-Film Series

Climbing-film plate type evaporator: Each unit is comprised of different types of two plates; materials are fed from middle section below the plate and the steam~water mixture is discharged from the large special-shape hole above the plate; steam enters from the small special-shape hole above the plate and condensate water goes out from the left and right opening below. Designed with low resistance corrugation, it guarantees even distribution of medium, low resistance, and high efficiency.

Compared to shell-tube evaporator, plate type evaporator has following advantages:

  1. Higher efficiency: in starch sugar and sugar alcohol industry, regarding trip|e-effect evaporation device, the average evaporation capacity of heat transfer area per unit may reach 30-50kg/m2-h. In juice industry, the average evaporation capacity of heat transfer area per unit may reach 30-70kg/m2-h.
  2. Small land coverage and compact structure: 20-30t/h large-sized evaporation device may be installed within places of 11*6m of height 4m.
  3. Short retention of the material: for four—effect evaporation device, it takes approximately 4 minutes for the materials to pass from first effect to the fourth effect and go out. It only stays for 2-4 seconds at the high—temperature position within the first effect, which is highly effective for the concentration of thermal materials.
  4. Low liquid holdup: due to the height of the evaporator, the static pressure of the fluid column is below 15kpa, which reduces the power of the material pump and minímizes the temperature difference of the fluid column (may be ignored).
  5. Easy installation and maintenance: installation of one four-effect concentration device may be completed within 7-12 days (depending on the evaporation capacity). The plate bundles may be taken off to be cleaned, replaced, increased, or decreased.
  6. Easy inspection: As all the equipment is usually inspected on a small planar area (such as 10*6 square plane), it is extremely convenient. Better effect may be achieved if there is PLC control available.
  7. Low investment cost for equipment: As new evaporation equipment, the price of plate type evaporator depends on the evaporation capacity. Usually for a 304 triple-effect plate evaporator with 10T evaporation capacity, the larger the evaporation capacity, more favourable the cost is.
