WZ type outer circulation type vacuum evaporation device mainly consists of a tube type heater, evaporator, circulating pipe and other ancillary equipment.
Liquid in the heater is heated to the boiling point of the pipe, water vaporization, heat energy is converted to the upward movement of the kinetic energy; at the same time because the heating tube liquid vapor mixture and the circulation tube without boiling liquid between the serious difference, in the expansion of kinetic energy and the serious difference induction, produce a material liquid natural circulating ( liquid heated in the tube within the circulation velocity of less than 1m/s ), the liquid material by heat, boiling the better, the circulation velocity is larger. Because it is in under the action of vacuum evaporation, the liquid evaporating temperature can be controlled in some way below 50 ℃. Evaporation of two steam wire net demister and liquid trap trapping, is the hydraulic jet pump water condensation. Evaporation tank liquid by centrifugal rotation, along the outer circulation pipe is recycled back to the heater, heating evaporation, so the cycle heating evaporation ( about 15-20 minutes ), when meet the requirement when the concentration of continuous discharge, start, at the same time also continuous feeding, thereby forming a continuous vacuum concentrating operation.

- In order to improve the effect of gas liquid separation, and both defoaming, prevent entrainment effect, using three stage separation, trapping: one is the vapor-liquid tangent into the evaporation tank using centrifugal force and tank sedimentation; two is the top of the high efficiency air filter evaporator type filtering net layer; three is the addition of impact type liquid trap, thereby preventing the material liquid is two steam entrainment loss, even for generating foam liquid ( e.g. soap containing Chinese medicine liquid ) can achieve the good separation effect.
- For ease of cleaning, in the top of the heater set quick open cover. In the evaporation tank air filter filter net is arranged at the upper part of the annular spray cleaning pipe. In the evaporation tank and is arranged on the manhole for tank cleaning.
- For convenience in operation of observation, in the top of the heater and the evaporation tank are arranged on the lamp hole and mirror.
- WZ type evaporator with the commonly used film type, falling film type, L - falling film evaporator, type WZ is a circulating type evaporator, liquid concentrate ratio, and the tube is not easy to scale. For example for the decocted liquid concentration proportion of up to d=1.25 and pipe scaling.

| WZ type evaporator can be widely used in medicine, food, chemical industry, light industry, industries such as water or organic solvent evaporation. Especially suitable for heat-sensitive materials ( such as traditional Chinese medicine production of water, alcohol extract, antibiotic fermentation liquid, milk, fruit juice, in the condition of vacuum low-temperature continuous concentration, can ensure the product quality.
