Drum Drying. The dmm or roHer dryers used for milk operate on the same principles as for other products. A thin layer or film of product is dried over an internally steam-heated dmm with steam pressures up to 620 kPa (90 psi) and 149°C. Approximately 1.2—1.3 kg of steam ate requited per kilogram of water evaporated. The dry film produced on the roHer is scraped from the surface, moved from the dryer by conveyor, and pulverized, sized, cooled, and put iato a container. 

Interestingly, the choice of LSDA is immaterial as long as its LSDR is 10 or less. The superior detergency of the above formulation using MES (TMS) as dispersant was confirmed by actual laundry bundle tests. It was also found that this type of formulation could be processed by spray-drying, drum-drying, or by various soap-drying processes. 

Because most food matrices are water soluble, many efforts were directed to the formulation of lipophilic pigments (mainly carotenoids) into water-soluble formulations (powders or gels). For hydrophilic pigments like flavonoids, polar dried microcapsules are the most popular ways to stabilize their functionality. Extracts rich in P-carotene were encapsulated using three different encapsulation techniques (spray drying, drum drying, and freeze drying)." ... 

Viscometer test. Typical crosslinked starches are obtained when the initial rise of the viscosity of the product is between 104° and 144° C, and the viscosity of the product does not rise above 200 Brabender units at temperatures less dian 130° C. The crosslinked starch slurry is then drum-dried and milled to obtain a dry product. The effectiveness of the product is checked by the API Fluid Loss Test after static aging of sample drilling fluids containing the starch at elevated temperatures. The milled dry product can then be incorporated into the oil well drilling fluid of the drill site. 

Amino Acid Content. Amino acid content of field pea products is related to protein level, method of processing, and fraction (starch or protein). The protein fraction contains fewer acidic (glu, asp) amino acids than the starch fraction and more basic (lys, his, arg) amino acids than the starch fraction. Also, there are more aromatic (tyr, phe) amino acids, leu, iso, ser, val, and pro in the protein fraction than in the starch fraction (5). An amino acid profile of pea protein concentrate shows relatively high lysine content (7.77 g aa/16 g N) but low sulfur amino acids (methionine and cystine) (1.08-2.4 g aa/16 g N). Therefore, it is recommended that air classification or ultrafiltration be used because acid precipitation results in a whey fraction which contains high levels of sulfur amino acids (12,23). Also, drum drying sodium proteinates decreases lysine content due to the Maillard reaction (33).

Vaisey et al. ( ) evaluated the performance of fababean and field pea concentrates as ground beef extenders. Sensory attributes of broiled meat patties containing the protein concentrates were more acceptable to taste panelists when these products were added as texturized flakes than as flour. The extended products had significantly less drip loss than all-meat controls but had softer textures. Texturizing the concentrates by drum-drying and flaking reduced their fat retention properties but produced patties more like the all-beef control. 

Synthetic detergents are marketed as liquids, slurries, drum-dried flakes and spray-dried beads, the latter being the form most frequently appearing in consumer packages. 

Drum dried flakes find their biggest outlet in industrial detergent mixtures where the original 30 to 90% active flakes are frequently dry-mixed with alkali builders for specific cleaning applications. 

Nonfat dry milk is produced from skim milk by condensing it with conventional equipment followed by spray or drum drying. The drum-dried product is relatively insoluble and is used principally for animal feeds. Over 95% of nonfat dry milk in the United States is used for human foods (American Dry Milk Institute 1982) and is produced by spray drying. Most instant NDM is made by rewetting the conventionally spray-dried product, allowing the particles to agglomerate, and... 

New Zealand workers have produced a crude /3-lactose from whey ultrafiltrate by roller or drum drying at a temperature greater than 93.5°C (Kavanagh 1975 Goldman and Short 1977). This product replaced up to 25% of the sucrose in a high ratio cake formula without adversely affecting cake size, tenderness, or sweetness (Goldman and Short 1977). 

HTST pasteurization cause similar losses of these vitamins, which are less than those caused by conventional sterilization and drum drying. Deaeration before heat processing stabilizes the water-soluble vitamins against heat-induced destruction and storage loss. 

Processing conditions are closely guarded trade secrets, but manufacturer s literature provides some information. The seaweed is extracted with hot water at slighdy alkaline pH. The aqueous extract is filtered and recovered by alcohol precipitation, dried, and milled. Drum-drying provides a less pure product. 

The energy requirements for doing have been studied rather intensively in recent years because the cost of a product can be markedly affected by this energy intense operation. Some researchers have observed that drying costs are much lower for air drying and drum drying than for freeze-drying. 

The ppt of CaC03 is removed by filtration, the soln of NaC102 is coned by evapn drum dried(Refs 2 3)... 

The juice vesicles, or "sacs," remaining after juice extraction and pulp-washing may be included in the portion of peel residue dried as cattle feed. However, it is feasible to recover and utilize this material as either frozen (3) or drum-dried juice sacs (44). 

After filtering oil, the calcium carbonate, the solution of sodium chlorite (NaC102) is evaporated and drum-dried.
