  1. 6. Real time estimations of kLa and viscosity in a fermentation pilot plant

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Arvid Norberg; [2022]
    Keywords : Oxygen transfer; Viscosity; Fermentation; Biotechnology; Direct method; kLa; OUR; DO; Online monitoring; Soft sensor; Fungus; Fungal fermentation; A. oryzae; A. niger; Herschel-Bulkley; Power law; Shear thinning; Novozymes; Enzymes; Technology and Engineering;

    Abstract : Fermentation is a process that utilizes live microorganisms to produce different biological products such as enzymes. The oxygen mass transfer rate is often the limiting factor in aerobic fermentations and thereby an important process parameter. READ MORE

  3. 7. Development of a Semisolid Baobab-based Protein Snack

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : David Bergman; Olle Wikner; [2022]
    Keywords : Baobab; Protein; Plant protein; Oat; Pea; Rheology; Development; Innovation; PDCAAS; Gel; Protein solubility; Food technology; Agriculture and Food Sciences;

    Abstract : This thesis was done in collaboration with the department of Food Technology at LTH, Aventure AB, and Arwa Foodtech AB. The aim of the project was to develop the base for a baobab based, spoonable protein snack, comparable to quarg but free from ingredients of animal origin. READ MORE

  4. 8. Temperature dependency of rheological properites of different dispersions containing microfibrillated cellulose

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Johanna Swanelius; [2022]
    Keywords : Microfibrillated cellulose; MFC; waxy maize starch; rheology; temperature; viscosity; complex viscosity; stready shear viscosity curve; amplitude sweep; dry content; dynamic rotational rheometer; Mikrofibrillerad cellulosa; MFC; vaxartad majsstärkelse; reologi; temperatur; viskositet; komplex viskositet; flödeskurva; amplitudsvep; torrhalt; dynamisk reometer;

    Abstract : Today, the focus lies on the state of the environment and how we can choose more sustainable alternatives to oil based materials. One material of interest is microfibrillated cellulose (MFC). READ MORE

  5. 9. DURABILITY STUDY OF REJUVENATED RAP BINDERS

    University essay from KTH/Kemiteknik

    Author : An Na Lay; [2022]
    Keywords : RAP reclaimed asphalt pavement ; rejuvenator; bitumen; rheology; ageing; RAP; bitumen; föryngringsmedel; reologi; åldring;

    Abstract : När priset på naturtillgångar ökar samt att industrier måste ställa om till en mer hållbar verksamhet innebär detta även en omställning för asfaltsindustrin. Ett sätt för att använda mer återvunnet material i asfaltsindustri är att använda bindemedlet från gammal asfaltsmassa (eng.: reclaimed asphalt pavement, RAP). READ MORE

  6. 10. Powder Rheology within AM production : Evaluating Compressibility, Permability, & Aeration for 316L Powders Within SLM Processes

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : André Leo; [2022]
    Keywords : Powder rheology; AM; Additive manufacturing; BPF; Powder bed fusion; SLM; Selective laser melting; FT4 powder rheometer; Compressibility; Permeability; Aeration; Pulver reologi; AM; Additiv tillverkning; BPF; Pulver bed fusion; SLM; Selektiv lasersmältning; FT4 pulver reometer; kompressibilitet; permeabilitet; luftning;

    Abstract : Additive manufacturing with the use of metals have been a steadily increasing field, being able to create products with a higher degree of complexity than traditional processing techniques. SLM is a popular AM process that uses metal powder as feedstock, and one of the key components of this process is the powder rheology. READ MORE
