Stainless steel spherical concentrator is an evaporative concentration equipment widely used in chemical, pharmaceutical, food processing, and environmental protection fields. Its unique design and materials give it an advantage in material handling processes.

1. Structural characteristics

The main body of the device is a spherical container, usually equipped with heating jackets or coils inside, providing heat sources through steam, electric heating, and other methods. The spherical design not only optimizes the force distribution (reducing stress concentration), but also expands the effective volume to surface area ratio, improving heat transfer efficiency. In addition, there is a feed inlet at the top, a discharge device at the bottom, and a vacuum system to reduce the boiling point temperature.

2. Evaporation process

After the concentrated liquid enters from the top, it rapidly vaporizes upon heating in a vacuum environment. Due to the smooth and symmetrical inner wall of the sphere, the material liquid forms a uniform thin film and slides down along the inner wall, increasing the contact area with the heating surface and accelerating the evaporation of moisture or other solvents. The secondary steam generated can be discharged through the top conduit for recycling and reuse; The concentrated material is deposited at the bottom and discharged. This dynamic cycle ensures high purity separation efficiency.

3. Vacuum assisted mechanism

When used in conjunction with a vacuum pump, the pressure inside the system can be reduced to a lower level (such as -0.1 MPa), causing the solution to boil at low temperatures and effectively protecting heat sensitive components from damage. For example, in traditional Chinese medicine extraction, this feature can prevent the effective ingredients from decomposing due to high temperature.

Precautions for using stainless steel spherical concentrator:

1. Parameter monitoring and adjustment: During operation, close attention should be paid to the changes in key parameters such as pressure and temperature of the spherical concentrator. Once abnormalities are detected, timely adjustments should be made to ensure the safe and stable operation of the equipment as well as the stability of the concentration quality.

2. Material characteristic considerations: Different types, concentrations, viscosities, and other properties of concentrated liquids may vary, which can affect the operational effectiveness of spherical concentrators. Therefore, when using, the operating parameters and methods should be adjusted reasonably according to the characteristics of the actual materials.

3. Cleaning and maintenance standards: Neutral aqueous solution should be used during cleaning to avoid using brushes or other hard objects to scrub the surface of the spherical concentrator, in order to prevent scratching the equipment surface and affecting its appearance and performance.

4. Requirements for seal replacement: When it is necessary to replace the seal, it is necessary to choose the corresponding model of product and ensure that its performance meets the requirements of the equipment to ensure the sealing and normal operation of the equipment.

5. Regular inspection and maintenance: During the maintenance period of the equipment, it is necessary to regularly inspect the various parameters, components, and sealing of the spherical concentrator, timely discover and solve potential problems, and extend the service life of the equipment.

6. Jacket liquid level management: The jacket should be submerged below the liquid level to ensure good heat transfer efficiency; At the same time, it should be noted that the concentrated liquid should not be parked overnight or left in the equipment for a long time to avoid affecting product quality and equipment lifespan.

7. Material liquid level control: The material liquid level should not be too high, otherwise it may cause material overflow or other adverse consequences, affecting the normal operation of the concentration process.

8. Maintenance of mechanical seal water blocking ring: During operation, the mechanical seal water blocking ring should always be filled with an appropriate amount of water to ensure the good performance of the mechanical seal and the normal operation of the equipment.

9. Safety protection measures: As spherical concentrators usually operate under high temperature and high pressure, operators must strictly follow safety operating procedures, wear necessary protective equipment, and prevent safety accidents such as burns and electric shocks.

10. Comply with GMP standards: The equipment and material contact parts are made of stainless steel material, which meets the requirements of GMP standards. During use, it is necessary to strictly follow GMP standards for operation and management to ensure the quality and safety of the product.
