Pumps are used to deliver varying quantities of liquid components into the liquid scales above the mixer. The liquid components are weighed precisely according to the recipe and then discharged into the mixer. Depending on the viscosity, the liquids are weighed using additive or lossin-weight feeders. For loss-in-weight feeders, the highly viscose liquids are partially discharged from the hopper with pressure support while the amount removed is weighed.

Key Points for Selecting a Mixer

Nowadays, cutting carbon dioxide emissions is an important issue in all sectors. When it comes to investments in automatic material handling systems for mixer feeding, criteria that were virtually insignificant years ago have suddenly gained importance. Energy efficiency has become significant in mixer feeding as well.

The type of mixing processes, i.e., continuous or batch, and whether the batches are fed as partial batches are key in selecting an efficient feeding method for raw materials. Cross contamination must be avoided at all costs, especially in a plant manufacturing products that contain allergens or are allergy-free, halal or kosher.

Mixer Design – What to Keep in Mind

Additionally, when designing the mixer, the output and batch size are important factors for planning. Another key criterion to consider while choosing the type of mixer is its use—is it going to be used purely for powder mixes, which need to be mixed sparingly and intensively, or powder and liquid mixes. The mixing process itself is also of crucial importance. The type of mixing function has a decisive effect on mixing times. The same applies to the mixing cycle time, which determines the type of mixer and the subsequent processes.
