    Continuous Dosing Liquids

    Continuous Dosing Liquids

    Mass or flow controlled

    Correct weighing of ingredients is essential for reaching the required product quality. If the various raw materials are not dispensed in the correct quantities to begin with, it will never be possible to produce a correct product. Therefore, Sobatech dedicated decades of time and effort in developing the most accurate feeding technologies available. As a result, the production process can reach accuracies that are only achievable on a system-controlled production environment.

    MEASURING EQUIPMENT

    For dosing the liquid ingredients of low, medium and high viscosity – Sobatech uses state-of-the art measurement equipment such as magnetic and Coriolis flow meters. These technologies are used to continuously regulate the correct quantity of liquid ingredients entering the continuous mixing system. Which measuring equipment is used depends on the visocosity and type of ingredient to be dosed.

    THE CORIOLIS FLOWMETER

    In the Coriolis principle, the flow rate is calculated by measuring the amount of mass of a substance passing through a device for a given amount of time. As soon as the liquid starts to flow into the measuring tube, this oscillation creates additional rotation caused by the liquid passing through. Two sensors detect this change in the tube’s vibration over time and this “phase difference” is a direct measurement of the mass flow.  This principle automatically corrects for changes in product temperature or density. This measuring technology is used for non-water based liquids like butter, shortening and oil.

    THE MAGFLOW METER

    In the Magflow principle, the flow is calculated by measuring the volume of a substance through a device over a given period. The magnetic flow meter’s sensor is placed inline and measures an induced voltage generated by the fluid as it flows through a pipe. With this type of flowmeter, you enter the fluids density upfront in the HMI – it does not automatically corrects for changes in density or temperature of the product. This measuring technology is used to dose water based liquids.
