We would like to start mixing flaked cereals and dried fruits for breakfast cereals like muesli.
Does anyone have experience what is the best mixer for this purpose?
Problem is that products that should be mixed vary very much in density (corn flakes, oat flakes, raisins, candied pinneaple cubes...), also structure of corn flakes should not be damaged. For mixer, I think experience from mixing instant soups where you mix dry vegetable and powder ingredients could be useful.
So far we tried with cubical tumbler mixer and we are not happy with results.

Dear Milos,

When mixing cereals in line (not in Batch) "Horizontal motion blending systems" could be a solutions. As vibratory conveyors can damage products and structures as well as demix your blend. I have seen horizontal motion systems combined with blending drums, which are used to mix products like you described.
Using these system is depending on the production capacity and the way the raw materials are supplied.

A simple system is to use a new/clean cement mixer for small batches. You will need to conduct some trials to ensure the ingredients are added in the correct sequence and then mixed for a set time to ensure that a almost homogeneius mix is obtained. Once yoy have consistent resuklts yoyu will have a saleable product.

What was recommended to us by manufacturer of food packaging and mixing machines was to make packaging line with at least 3 feeding lines with separate scales so each component(or premix) would be measured and added according to recipe for each bag. Because of great difference in density they don't think that we will have good result in bags if we mix batch of product and then package it on single line.
