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.

Drum Drying – What is it?

Potato Flakes & More With Drum Drying 101

Drum dryers were developed in the early 1900s. They were used in drying almost all liquid food materials before spray drying came into use. Nowadays, drum dryers are used in the food industry for drying a variety of products, such as milk product, baby foods, breakfast cereal, fruit and vegetable pulp, mashed potatoes, cooked starch and spent yeast.

A couple of very well known examples of the type of product produced in this type of machinery is baby cereal in the form of flakes or mashed potatoes in the form of flakes. I read an article recently that said Potato Flakes are considered a comfort food!  (Visit the blog for www.movethefood.org – a non-profit organization feeding the hungry in Iowa)

Drum drying is one of the most energy efficient drying methods, and is particularly effective for drying high viscous liquid or pureed foods.

In a drying operation, liquid, slurry, or puree material is applied as a thin layer onto the outer surface of revolving drums that are internally heated by steam. After about three-quarters of a revolution from the point of feeding, the product is dried and removed with a static scraper. The dry product is collected and is transferred (usually pneumatically) to a rotary hammer mill, reduced to the desired particle size and packaged. In order to ensure that the product is consistent and that it meets customer specifications, a delicate balance between feed rate, roll speed, steam pressure and roll gap must be achieved.

SYSTEM DESCRIPTION

A drum dryer consists of one or two horizontally mounted hollow cylinder(s) made of high grade cast iron, fabricated steel or stainless steel, a supporting frame, a product feeding system, a scraper, and auxiliaries. A typical drum dryer may have either a single drum with smaller applicator rolls or double drums. The diameter of typical food drums ranges from 24” (60 cms.) to 60” (152 cms.) and lengths that go from 24” (60 cms.) to 144” (365 cms.).

THE ADVANTAGES OF DRUM DRYING ARE:

• Products have good porosity and hence good rehydration due to boiling evaporation.
• Drum dryers can dry very viscous foods, such as pastes and gelatinized or cooked starch, which cannot be easily dried with other methods.
• Drum dryers normally have high energy efficiency
• Drum drying can be clean and hygienic.
• Drum dryers are easy to operate and maintain.
• The dryers are flexible and suitable for multiple but small quantity production

What Does a Drum Dryer do?

Operating Principle of a Single or Double Drum Dryer

A drum dryer is basically a conduction dryer. A wet feed film (in liquid or paste form) is applied to a rotating metal cylinder or a pair of metallic cylinders, that are heated inside with steam. Material film dries to the final moisture level and is scraped off the drums via a set of knife-blades.

Special Features of a Drum Dryer:
  • Suitable for handling liquid or pasty feeds.
  • Product in powdery, flaky form.
  • Uniform drying due to uniform application of film.
  • Medium range capacities.
  • Very High thermal efficiency.
  • Minimum Thermal degradation.
  • Continuous operation.
  • Accomplishment of drying in single step, eliminating need for any intermediate concentration processes.
Applications:

Paraffin wax, Clay, fire clay, plaster slag, incinerating and composing refuse, waste products, residue and sewage sludge, agricultural products , greenstuffs, grain, root vegetables, etc.
