Spherical vacuum concentration tank is a widely used equipment in the pharmaceutical, food, chemical and other industries, mainly used for the concentration, distillation and recovery of organic solvents in feed liquids. Its core design combines the advantages of vacuum negative pressure technology and spherical structure, ensuring an efficient and gentle concentration process, especially suitable for heat sensitive material processing.
1、 Structural composition
The device is mainly composed of the following components, which are connected in a closed manner to ensure that the material completes the concentration process under reduced pressure:
1Concentrator bodySpherical design, using a jacket structure, with stainless steel material (such as SUS304/316L) in contact with the inner layer, meeting hygiene standards; Heating medium (such as steam) is introduced into the interlayer for uniform heat transfer. The spherical structure optimizes the heating area and fluid dynamics, reducing material residue.
2condenserUsually designed in a tubular manner, located at the top of the tank, it is used to condense and evaporate water vapor or organic solvent vapor to prevent material loss.
3Vapor-liquid separatorImmediately after the condenser, the gaseous and liquid components are separated by flow separation or centrifugation to ensure that pure steam enters the condensation stage and improve the concentration purity.
4Liquid receiving bucketCollect condensed liquid for subsequent processing or solvent recovery. The system supports fully sealed operation to reduce environmental pollution.
5vacuum systemIncluding hydraulic jets or vacuum pumps, used to maintain a low-pressure environment inside the tank, reduce the boiling point of liquids, and achieve low-temperature evaporation.
2、 Working principle
1Feeding and HeatingThe material is drawn into the tank by gravity or vacuum, and the interlayer heating medium raises the temperature of the material liquid. Under vacuum negative pressure conditions, the boiling point of the liquid significantly decreases, accelerating the evaporation process.
2Evaporation and Separation: The feed liquid generates steam after boiling, and then enters the vapor liquid separator after the foam is eliminated by the demister. The separator efficiently intercepts liquid droplets, and pure steam is introduced into the condenser.
3Condensation and CollectionSteam is cooled into liquid in the condenser, and the efficiency is enhanced by external circulating cooling water before finally flowing into the receiving tank. The solvent recovery rate is high and suitable for the reuse of industrial solvents such as alcohol.
4environmental controlThe vacuum system continuously adjusts the pressure to avoid high-temperature damage to the thermosensitive components, while reducing oxidation reactions and maintaining material color and activity.
3、 Application advantages
1Efficient concentrationSpherical design optimizes heat transfer, shortens processing time, and achieves a concentration ratio of 1.3, significantly improving production efficiency.
2Material protectionLow temperature vacuum environment to avoid degradation of heat sensitive components, suitable for traditional Chinese medicine extracts, fruit juice, dairy products, etc.
3environmental protection and energy conservationThe fully sealed process reduces solvent loss (less than 5%), reduces dust and exhaust emissions, and meets green production requirements.
4Easy to operateThe modular structure is easy to install and maintain, supports production needs with small batches and multiple varieties, and is widely used in the pharmaceutical and food industries.
Through the above structural principles, the spherical vacuum concentration tank has achieved a mild and efficient concentration process, becoming an important equipment in modern industry.
