Structure characteristics and advantages of heated vacuum evaporator May 26, 2018

At present, the heated vacuum evaporator is mainly used in evaporation of water or organic solvent solution in the pharmaceutical, food, chemical and light industry industries. In particular, some heat-sensitive materials, using a heated vacuum evaporator for continuous condensation at low temperatures under vacuum conditions, will ensure product quality.

 

Heating the vacuum evaporator In the process of evaporation, according to different specifications, the user can select the evaporation device that the device is versatile. It can not only evaporate the aqueous solution, but also can be used to recover the organic solvent solution evaporation; it can be operated under vacuum. , It can also be operated under normal pressure. For example, water produced in Chinese medicine, alcohol extracts, antibiotic alcohol solutions, milk, fruit juices, etc., can be used to complete the evaporation and condensation.

 

The heating vacuum evaporator has several features in terms of structure: 1. In order to avoid contamination of the material, high-quality stainless steel is used for all parts in contact with the material; 2. To improve the vapor-liquid separation effect, both defoaming and anti-entrainment are provided. The role of the use of two-stage separation, in order to achieve a satisfactory separation effect; 3, for ease of cleaning, in the top of the heater is set to a quick-opening top cover and thus in the evaporation tank in the upper part of the air filter type filter set a special ring Spray cleaning water pipes.

 

At the same time, a manhole is specially set on the evaporation tank of the heated vacuum evaporator to facilitate cleaning. In addition, lamp holes and sight glasses are also provided on the top of the heater and the evaporation tank to facilitate observation in real time during operation. The advantage of this equipment is that it not only can evaporate and concentrate a variety of materials, but also the concentration ratio of the feed liquid is large, and the scale inside the tube is not easy to scale.

 

In a heated vacuum evaporator, the main components included are: a tubular heater, an evaporation tank, a circulation pipe, and other components, and the material liquid is heated to a boiling point in the heater tube, and partially vaporized to convert the heat energy. Kinetic energy for upward movement. Heating the vacuum evaporator The liquid in the evaporation tank will return to the lower part of the heater along the outer circulation pipe under the action of the centrifugal force, and will be heated and vaporized by recirculation. When the required concentration is reached, the material will be discharged.
