| Abstract: | The traditional application of small diameter multiple hydrocyclone batteries in the starch industry is the refining of maize, wheat, potato, and manioc starch by countercurrent washing in multistage operation. A new type of multiple hydrocyclone battery for these purposes is discussed. Construction details, internal flow passage, selection of construction material, and some operational characteristics of the battery are taken into consideration as well as its easy, handling. As an example of application of a small diameter hydrocyclone system, a new process alternative for manufacturing of potato starch is presented. The process has a fresh water consumption for starch extraction and refining of 300–350 l/t potatoes or ∼ 1.9 – 2.2 t of water per ton of refined DS starch, due to the unique combination of process stages by adapting a hydrocyclone system, screens, and centrifugal separators. |
