A dosing machine is the core of any process that requires precision ingredient addition. It is engineered to deliver a precise, repeatable quantity of material, either by volume (volumetric) or by weight (gravimetric). We design and build standalone dosing stations or fully integrated modules for applications ranging from final product filling to in-process batching and continuous feeding.

The consistency of your final product is directly determined by the accuracy of your dosing system. We provide the technological solution that matches your accuracy and material requirements. For powders, auger dosers offer excellent volumetric control, while gravimetric loss-in-weight feeders provide the ultimate weight-based accuracy for critical ingredients. For liquids, we utilize everything from piston dosers for pastes to peristaltic pumps for sterile fluids and flowmeters for bulk liquids. Each system is engineered not just to dose, but to integrate seamlessly into your control architecture for full process automation

For Powders: Volumetric Auger Dosing, Gravimetric Loss-in-Weight Feeders, Vibratory Feeders

FAQ -

Q1: What is the main difference between volumetric and gravimetric dosing?
A1: Volumetric dosing dispenses a set volume (e.g., via auger rotations or piston stroke). It is fast and cost-effective, but its weight accuracy can be affected by changes in the material's bulk density. Gravimetric dosing dispenses a set weight. It is more accurate as it continuously measures weight, making it the standard for high-value or critical ingredients.
Q2: What exactly is a "Loss-in-Weight" feeder?
A2: A Loss-in-Weight feeder is a highly accurate gravimetric system. The entire feeder and its hopper are placed on load cells (scales). To dose, the system controls the speed of the screw or pump to make the entire assembly "lose weight" at a precise, controlled rate. It provides exceptional accuracy for both continuous and batch dosing.
Q3: Our powder's density changes from batch to batch. How do we ensure accurate dosing?
A3: This is precisely the problem that a gravimetric (weight-based) dosing system solves. Since it measures and controls based on weight, it is immune to variations in bulk density. It will automatically speed up or slow down the dosing screw to ensure the target weight is always achieved.
Q4: Can you provide a system that doses multiple ingredients into one mixer?
A4: Yes. We build multi-ingredient batching systems. This typically involves a station with several individual dosing machines (one for each material), each controlled by a central batching controller. The controller runs a recipe, calling for the precise amount of each ingredient in the correct sequence.
Q5: How do you handle materials that are difficult to feed, like sticky powders or interlocking parts?
A5: This requires specialized design. For sticky powders, we might use special auger designs, flexible hopper walls, or mechanical agitators. For interlocking parts, a standard vibratory bowl might not work, and a more advanced centrifugal feeder or a step feeder might be required. We analyze the material first to select the right feeding technology.
