Dosing is a key stage in technological processes, involving the precise delivery of a defined amount of raw material or product, which is then directed to further processing, mixing, granulation, or packaging.
The purpose of dosing is to ensure repeatability, accuracy, and full control over the quantity of materials introduced into the process, which directly affects product quality and production stability.
Industrial dosing systems allow regulation of feed intensity.
The process can be carried out in both continuous and batch mode – crucial in applications requiring strict maintenance of component ratios. Depending on technological requirements and material characteristics, different types of dosing systems are used.
Types of Dosing
Volumetric Dosing
- Based on delivering material according to a defined volume.
- Implemented using screw feeders or rotary (cell) feeders.
- Used where a stable material flow is important and a certain volumetric error tolerance is acceptable.
- Key advantages: simple design, low cost, and fast high-capacity dosing.
Gravimetric Dosing
- Based on precise dosing by weight (e.g., kilograms), using scales or weighing systems.
- Can be carried out in batch mode (batch weighing) or continuously (measuring mass change over time).
- Ideal for applications requiring high accuracy and material accounting.
- Key advantages: highest precision, full control, and recording of dosed quantities.
Main Advantages of Dosing
Accuracy and repeatability
- Ensures consistent final product quality.
Optimization of raw material usage
- Minimizes material losses.
Increased production line efficiency
- Thanks to automation and process stability.
Reduction of operator errors
- Eliminates manual weighing or feeding.
Full integration capability
- With control and automation systems (e.g., SCADA, PLC).
