efficient process for the production of permeate powders

Jun 01, 2017 · During the production of permeate and whey powders, spray drying is used to convert a concentrate into a powder. A new process based on (1) overconcentration of the concentrate from 60 to 80% w/w DM, (2) granulation of the paste with recycled powder at 97% w/w DM to obtain granules at 88% w/w DM, and (3) final drying from 88 to 97% w/w DM has been developed to replace this energy …

powder production technologies - powder metallurgy review

Finally, there is a range of chemical conversion processes, with the leading example being the carbonyl process for the production of fine nickel or iron powders. In this process, the crude metal is reacted with CO under pressure to form the carbonyl, which is gaseous at reaction temperature, but decomposes to deposit the metal on raising temperature and lowering pressure

fundamentals of ceramic powder processing and synthesis

fundamentals of ceramic powder processing and synthesis

In most cases, ceramic powder precursors (that is, sulfates, carbonates, oxalates, hydroxides, etc.) are produced by precipitation. These powders must be thermally decomposed to their oxides in a separate step that frequently maintains their precipitated particle morphology, although some degree of particle sticking often occurs

innovations in dairy processing and milk powder processing

innovations in dairy processing and milk powder processing

Milk powder production involves many thermal processes, making it highly energy-consuming. In the past decades, the current production process is optimized to a high extent. The introduction of new milk powder technology will be the key. Optimization of single process units will have an influence on up- and downstream process units

wo1995014644a1 - a process for production of ceramic

A process for spray drying of ceramic suspensions for the production of a powder which is dust free, sufficiently stable for storage and with good flow characteristics. The ceramic suspension is spray dried in a chamber (1) to a powder with a water content which is 0.1-10 % higher than required in the final powder and hereafter fluidized in a fluid bed (6) with ambient air for an evaporative

a review on influence of spray drying process parameters

a review on influence of spray drying process parameters

The dried dosage forms of medicinal plants are preferred than liquid presentations because of their higher stability. The spray drying technology is the most employed process to produce dried extracts from medicinal plant liquid extracts. These powders need to meet certain physicochemical (e.g., moisture content, hygroscopicity, particle size, density, the concentration of active ingredients) and mechanical …
