Common Models (By Evaporation Capacity & Daily Processing Capacity)

1. Small Type (Laboratory & Pilot Test)

   0.5–1 t/h (12–24 t/d): Skid-mounted, mainly falling film type, 304/316L stainless steel, for food and pharmaceutical lab tests

   2–3 t/h (48–72 t/d): Small-scale production, traditional Chinese medicine extraction and fruit juice concentration
2. Medium Type (Most Popular, accounting for 60% market share)

   5 t/h (120 t/d): Standard MVR evaporator, 316L stainless steel / titanium material, applied in chemical, pharmaceutical and high-salt wastewater treatment

   10 t/h (240 t/d): Mainstream model, mostly forced circulation type, for high-salt wastewater and crystallization process

   15–18 t/h (360–432 t/d): Large-scale production, new energy lithium battery, coal chemical industry and zero-discharge wastewater treatment
3. Large Industrial Type

   25–30 t/h (600–720 t/d): Combined multi-effect and MVR structure, for high-salt, electroplating and printing & dyeing wastewater

   Above 50 t/h: Customized equipment for large-scale environmental protection, coal chemical and salt chemical industries

3. Material Selection (Material Contact Parts)

   Working Principle of Used MVR Evaporator

   MVR refers to Mechanical Vapor Recompression Evaporator. It recycles heat energy of secondary vapor by mechanical compression to cut energy consumption.

   1. Raw material is heated and boiled inside the chamber, generating low-temperature and low-pressure secondary vapor.
   2. The vapor compressor sucks in secondary vapor, raising its pressure and temperature through compression.
   3. Heated vapor flows back into the evaporator and serves as heat source to heat raw liquid again.
   4. Vapor condenses into clean water after heat release, while the liquid material gets concentrated continuously. Concentrated material will be discharged when reaching required density.
   5. The whole system runs in closed cycle. It barely needs fresh steam supply, and only consumes electric power to maintain evaporation.
