The equipment can be used in pharmaceutical, food, chemical industry and other industries for the concentration and distillation of small batch of liquid materials and the recovery of organic solvents, as well as the evaporation recovery of production waste water. It is mainly applicable to the pilot production or laboratory Test Research of enterprises with small production capacity. The equipment can be operated under negative pressure or atmospheric pressure, and can also be used for continuous or intermittent production. It can be applied to a variety of materials and has strong versatility.Spherical concentration tank is mainly composed of the main body, condenser, vapor-liquid separator and liquid receiving barrel. It can be used for concentration and distillation of feed liquid and recovery of organic solvent in pharmaceutical, food and chemical industries. Due to the use of vacuum concentration, the concentration time is short and the effective components of heat sensitive materials will not be damaged. The equipment and material contact parts are made of stainless steel, with good corrosion resistance and durability.
