Energy-saving/Heat Pump Double-Effect Concentrator

SHINVA double-effect concentrator for vacuum concentration of liquid materials in pharmaceutical, traditional Chinese medicine, food and chemical industries. In the energy-saving version, the first-effect secondary steam is used as the heat source of the second effect, increasing energy utilization. In the heat pump version, the first-effect secondary steam is compressed and reused for second-effect heating, generating significant boiler steam savings and reducing production costs. The equipment consists of a heat pump system (or vacuum), first-effect heating chamber, first-effect evaporation chamber, second-effect heating chamber, second-effect evaporation chamber, condenser, liquid receiving tank, pipes and valves.

Key specifications

  • Principle: first-effect secondary steam reused in the second effect
  • Heat pump: compresses secondary steam for second-effect heating
  • Composition: heat pump system (or vacuum), heating and evaporation chambers of both effects, condenser, receiving tank, piping and valves
  • Live steam pressure: 0.5–0.7 MPa
  • First effect: heating at 90 °C and evaporation at 75 °C
  • Second effect: heating at 75 °C and evaporation at 55 °C
  • Energy saving index: 0.33–0.37 kg steam/kg water evaporated
  • Saving: about 34% energy and 30% water compared to double-effect without heat pump

Applications

  • Pharmaceutical industry
  • Traditional Chinese medicine
