What is Food powder processing?
Similar to other process industries, the food industry deals with a great number of raw materials and products in powdered or particulate form. Theoretical and application principles of food powder processing will be discussed in an effort to provide basic tools to improve knowledge and understanding of this focused discipline. 2. Comminution 2.1.
What is the PF of a powder?
Typical PF for loose powders: 0.5 and 0.7 powders of various sizes vs. uniform size Compaction Pressure increases packing Porosity (P) - Ratio of the volume of the empty spaces in the powder to the bulk volume. (P+PF=1)
What are the advantages and disadvantages of powder metallurgy?
Powder Metallurgy (PM) (around 1800s) Pressing – Powders are compressed into the desired shape in a press-type machine using punch-and-die tooling designed specifically for the part. Sintering - Heating at a temperature well below melting. Advantage Near-net shape, No waste, controlled porosity,Dimension control better than casting Disadvantage
What is the bulk density density of powders in the loose state?
Bulk density density of the powders in the loose state after pouring bulk density ? true density Typical PF for loose powders: 0.5 and 0.7 powders of various sizes vs. uniform size Compaction Pressure increases packing Porosity (P) - Ratio of the volume of the empty spaces in the powder to the bulk volume.
