Slurry Systems

 

Slurry systems are used to apply oil and seasoning mixtures or water-based mixtures on the base product. Using a mono-layer system as with the VLPS design, we can provide better application control, more uniform coverage and less breakage than tumbling drums.

These systems vary greatly based on the application requirements, ingredients and local conditions. GOE has experience with numerous different mixtures and conditions and there is no substitute for some testing to determine the required system elements. All aspects of a slurry system are critical as a failure in any area will lead to a full system shutdown very quickly.

Keeping the slurry in suspension is often the most important criterion and we typically make slurry systems shorter overall length to collect overspray rapidly. Reservoir mixing and body flushing are common features to minimize solids from separating. Jacketing for heating or cooling is another common option as ingredient sensitivity to temperature is often overlooked.

Slurry systems will have to address the mixing and buffer capacity to allow the system to run when a new batch is made. Determining the amount of time between mixing and the maximum time that a mixture can be held before application are key criteria in the tank sizing. Mixing, transfer and circulation are all important. In some cases, different components are required for different mixtures.
