Dried Products Processing

Dried Foods & General Dried Product Processing

Dry product, like baby cereal, dried fruit or vegetables, is produced by drying on the steam heated drums of a drum dryer is usually conveyed, cooled, sized, screened, accumulated and stored for packaging, and finally filled into a commercial package for sale. Our DDR basic dry product processing and packaging system technical bulletin describes the elements of the equipment and operations dedicated to accomplish this objective after the drum drying process.

Drum Dryer Food Product Processing

The dry product leaves the drum dryer  as a hot material due to the drying process. It also leaves the dryer in random sized pieces since the product is scraped from the drying rolls into an accumulating conveyor.

Product specifications usually call for a uniformly sized product flake, particle, or powder form and cooled to ambient temperature for proper storage and packaging. Also, variations in the final product characteristics due to the formulation and processing of the product slurry may occur. This requires the accumulation and blending of various segments of the dryer production to yield a more uniform final product. Read more in our DDR16 Technical Bulletin click here.

Drum Dryers & Room Ventilation

Optimum Operating Conditions for Drum Dryers

Optimum operating conditions for your food or pharmaceutical drum dryers, or any other type of drum drying process, is important.

Humidity in the dryer room can cause undesirable condensation on ceilings and walls. The walls and ceilings should have an insulating valve, high enough to insulate the interior room surfaces from cooler outside temperatures and prevent the water vapors from condensing. Each dryer room should be evaluated and designed to specifications which take into account the physical operating conditions of the drum dryer, the product being produced, the interior room environmental conditions, and the exterior plant environmental conditions.

The drum dryer must operate in a uniform controlled environment in order to produce a uniform controlled product. Variations in humidity, temperature, and air currents in the dryer room can affect the overall productivity of the drying process, the stability of the gap between the dryer drums, the percent of moisture in the final product, and other factors related to the drying process. A qualified ventilation engineer should establish the dryer room ventilation conditions and specifications for a particular production installation.

Drum Drying Resources can provide data and review the recommendations for conformance to proper conditions for drum drying. Drum Drying Resources supplies new, rebuilt, and retrofitted Double Drum Dryers to the drying industry. Each dryer is configured to specific designs, specifications, and systems to produce your product at maximum quality, sanitation, and productivity levels.

Dry Product Processing

How is Dry Product Processing Done on A Drum Dryer?

Dry product produced by drying on the steam heated drums of a drum dryer is usually conveyed, cooled, sized, screened, accumulated and stored for packaging, and finally filled into a commercial package for sale.
