How to choose evaporators

  • In the cbd industry, evaporators are widely used in alcohol | ethanol recovery and solvent removal. There are many types of evaporators on the market, and each has its own advantages, mainly including rising film evaporator, scraped film evaporator, falling film evaporator, rotary evaporator. Which evaporator should we choose to meet our actual needs?

    • Rising film evaporator

    High evaporation efficiency, low equipment height, for effective space saving. So if you want to do cbd concentration for alcohol recovery after hemp crude oil extraction process, TOPTION engineers first recommend that you consider a rising film evaporator.

    Simple working principle – The feed liquid is preheated to the boiling point, is added from the bottom of the heating chamber, and is vigorously vaporized in the heating tube, so that the generated steam drives the feed liquid to rise in an evaporator in a film shape along the wall of the tube. The solution only needs to pass through the heating tube once to achieve the required concentration. Rising film evaporator is suitable for dilute solutions and heat-sensitive materials with low concentration.

    • Wiped film evaporator

    Wiped film evaporator is a kind of high efficient evaporators, if the viscosity of the fluid exceeds 100 Pa.s, TOPTION engineers recommend wiped film scraper evaporator.

    Use wiped film evaporator, alcohol collection rate is high, almost no waste, 95% are collected. You could achieve higher purity in both light and heavy phases after separation.

    • Rotary evaporator

    The advantages of rotary evaporator is its economical cost,compared with wiped film evaporator, the premise investment cost is slightly lower. Good acid resistance. TOPTION rotary evaporator 1L ~ 100L wide capacity range flexible design. Dual condenser, explosion proof design, professional customization.
