Abstract
A blending scale for dosing and blending two products. The blending scale includes an auxiliary product dosing device, and an auxiliary product dispenser receiving the auxiliary product from the auxiliary product dosing device and releasing the auxiliary product within a dynamic unconstrained stream of the main product to produce and maximize a blend of the auxiliary and main products. A blend collector measures a quantity of the blend of the auxiliary and main products. A controller controls release of the auxiliary product in a synchronized manner with the dynamic unconstrained stream of the main product, based on the defined quantity of the auxiliary product measured by the auxiliary product dosing device. The dynamic stream of the main product is terminated once a targeted quantity of the blend measured by the blend collector is obtained. A method for accurately dosing and homogeneously blending two products is also disclosed.
