Little knowledge about vacuum mixer
Why vacuum mixing?
Vacuum refers to space in which pressure is lower than atmospheric pressure. In other words, it contains less gas molecules per unit volume compared to ambient air.
Vacuum environments accomplish a number of mixing goals that vary from one application to another. For some, it is a matter of aesthetics, like in the case of coatings, personal care products or molded composites. A void-free mixture also contributes to the strength and precision of specially engineered parts. In other products, vacuum is applied to remove oxygen and prevent decomposition of sensitive ingredients or thwart unwanted chemical reactions and microbial growth.
Applying vacuum also improves product handling and performance. Certain gels and pastes are mixed under vacuum to prevent defects in syringe filling or printing. Finally, vacuum mixing allows drying processes to proceed faster and at lower temperatures.
Vacuum-capable mixers
Almost all batch mixer configurations can be built for vacuum operation, from single-shaft devices such as high speed saw-tooth dispersers or rotor/stator mixers used for making low viscosity formulations to multi-agitator or planetary mixing machine used in batching high viscosity, high density compounds or even blending equipment used in drying operations.
Advantages of A Vacuum Mixing Machine:
- Low initial costs for the purchase of equipment, suitable for start-ups and for developing new formulations and the manufacturing of test batches.
- Ability to handle a wide range of liquid, pasty, viscous, and highly viscous products.
- Minimum load 15% of the volume of the container.
- High performance.
- Robust design and long trouble-free service life.
- Quick change to produce a new type of product.
- Easy to work, maintain, and clean design.
- Low operating costs and low resource consumption.
- Low noise.
