Volumetric dosing technology integrates into continuous lines

Volumetric dosing pumps the material at steady intervals. Based on the dispersion principle, volumetric dosing equipment relies on a pre-calculated timeframe to move the mixture.

For example, if a drug in a liquid phase takes 10 seconds to reach the desired concentration, your dosing system will be configured to displace the mixture at that rate. Volumetric dosing technology is suitable for continuous processes. However, the revolving screws that move the mixture may subject the ingredients to unwanted pressure or fluidization.

Use gravimetric dosing equipment when accuracy is more pressing

The gravimetric dosing technique is also known as loss-in-weight system because the feeder determines the dose based on the change in load. This mechanism is self-calibrated, and the dosing can be as accurate as the sensitivity of the check weigher unit, down to the slightest gram.

One of the drawbacks of gravimetric solutions is that the process must be stopped during refilling, so the dosing equipment typically fits batch production.

Microdosing solutions are suitable for highly-concentrated materials

Some product formulations are especially sensitive to the concentration of ingredients. Pharmaceutical formulations with high-potency API, for example, risk destabilizing the composition if not properly dosed.

The finer the particles of the material, the higher their concentration. Microdosing solutions account for these subtle changes by applying gravimetric methods to ultra-light masses counted in milligrams.

Integrate a flow meter with the dosing system for liquid materials

Dosing equipment products are set up differently from technology made for powder dosing. Besides a dosing pump that moves the liquid at pre-defined intervals, the machinery integrates a flow meter to measure the quantity of liquid dispersed.

Some liquids, like beverage mixtures or cosmetic formulations, may develop air bubbles that alter the dosing process. The sensor system in a flow meter detects these distortions before the liquid is pumped into the filling station or further processing.

Combine gravimetric and volumetric techniques to dose powders

Flowability is a primary challenge when manufacturing powder products. Dosing systems for powders must ensure that particles do not stick to the equipment and maintain a steady flow. While volumetric technology drives the material homogeneously, it lacks the self-regulating calibration of gravimetric methods.

Combining the two techniques, integrated dosing systems overcome the flowability problem without compromising dosage accuracy. At the same time, this solution allows continuous processing.
