Introduction
Solvents are widely used in natural plant extraction processes, such as ethanol extraction, hexane extraction, and water extraction. However, it is necessary to separate the solvent from the product to make it usable. This is achieved using a solvent evaporation machine or solvent concentration device. The following diagram illustrates a spherical solvent evaporation device, which operates under vacuum.
Structure
This spherical evaporator consists of a spherical evaporation chamber, a separator, a condenser, a cooler, a receiver, a vacuum system, as well as pipes and valves.

How does it work?
The spherical evaporator operates under vacuum. Heating is provided by steam or thermal oil, depending on the customer's requirements. The temperature is controlled to evaporate the solvent, which has a low boiling point. The vaporized solvent passes through a gas-liquid separator and is then condensed by a condenser and cooler. The liquefied solvent is collected in the receiver. The equipment is equipped with an agitation system to prevent material from adhering to the pan. Additional liquid material can be added during operation to enable continuous processing.
Applications
This spherical evaporator is suitable for concentrating high-viscosity, high-concentration, and crystallization-prone products across various industries, including:
1.Pharmaceutical Industry: Concentration of herbal extracts, purification of active pharmaceutical ingredients (APIs), and recovery of solvents from synthesis processes.
2.Food Industry: Extraction and concentration of plant-based oils, flavors, and nutrients; production of syrups and natural colorants.
3.Chemical Industry: Recovery of solvents from chemical reactions, purification of intermediates, and treatment of high-viscosity solutions.
4.Biotechnology and Bioengineering: Downstream processing of fermentation broths, enzyme concentration, and preparation of biomolecules.
