Reclamation of whey on the example of the dairy plant

Celem pracy przedstawionej w artykule była analiza możliwości zagospodarowania serwatki w przemyśle spożywczym. Ponadto przedstawiono technologię produkcji i zagospodarowanie wstępnie zagęszczonej serwatki na przykładzie wybranego zakładu mleczarskiego. Wykorzystanie serwatki w proszku daje szereg możliwości w projektowaniu nowych produktów spożywczych na skalę przemysłową.The aim of the paper was the analysis of possibilities of the reclamation of whey in the food industry. In addition, the whey transformation technology and the utilization of preconcentrated whey has been presented on the example of a specific dairy plant. In addition, use of whey powder provides a range of opportunities in design of new food products on an industrial scale

Roughness Parameters Calculation By Means Of On-Line Vibration Monitoring Emerging From AWJ Interaction With Material

The paper deals with a study of relations between the measured Ra, Rq, Rz surface roughness parameters, the traverse speed of cutting head v and the vibration parameters, PtP, RMS, vRa, generated during abrasive water jet cutting of the AISI 309 stainless steel. Equations for prediction of the surface roughness parameters were derived according to the vibration parameter and the traverse speed of cutting head. Accuracy of the equations is described according to the Euclidean distances. The results are suitable for an on-line control model simulating abrasive water jet cutting and machining using an accompanying physical phenomenon for the process control which eliminates intervention of the operator
