Application Example:
Breakfast Cereal Mixing and Extrusion

Mixing application: Traditional vs. Modern
The traditional process of Mixing of breakfast cereals with dried fruits (e.g. raisins, apple pieces, nuts, banana slices) involves feeding all ingredients one after the other into a vessel.

The total batch is then mixed, but obtaining a homogenous mixture is difficult because the ingredients generally have large differences in particle size, shape or density. There is also the risk of destruction of shear sensitive ingredients.

Extrusion Application: Traditional vs. Modern
Cereals or a mixture of cereals are formed in a way to make their shape more attractive and more consumer-friendly.

The Traditional process involves separate weighing and feeding of liquids and dry cereal ingredients (whole grains and grits), with ingredients fed into rotary cereal cookers on an automated batch basis.

Passing steam under pressure through the cooker then gelatinizes the cereal. Because the cereals tend to agglomerate in a cooker, the cooked grains are discharged into lump breakers to break up the cereals.


Application Example:
Ice Cream Ingredient Feeding

The ice cream manufacturing industry is highly susceptible to fluctuating costs in value-added ingredient additions, as well as product quality affected by the percentage of these ingredients in the mix.

Ingredients added to the semi-frozen ice cream base mix are typically called "inclusions? Inclusions can be comprised of anything from marshmallows to chocolate chips to coconut flakes.

By closely monitoring the percentage of these high value inclusions in the mix, the manufacturer is assured of cost control and savings, as well as continued product quality.

This application example shows how to replace existing fruit feeder technology in order to achieve a higher degree of accuracy in the feeding of high quality, costly ice cream ingredients without damage to the individual ingredients. In addition, the design must meet the stringest cleanliness standards of the dairy industry, with minimal downtime for disassembly and cleaning operations.
