3 Linked activities SIG 10 Fluid mechanics of Cleaning and Decontamination Fouling and Cleaning in Food Processing 2018 The food-water-energy challenge April 2018, Lund, Sweden 3
4 Two questions Q1 Why clean? Q2 How clean is clean? to purge to prevent cross-contamination to restore performance to inhibit microbial growth or deposit accumulation 4
5 Cleaning is all about surfaces and s Surface 3 Surface 4 Soil 1 Soil 2 5
6 Interface engineering fluid- interactions fluid/solution (usually water) - interactions 6
7 How physical scientists see cleaning fluid mechanics normal stresses liquid adhesion mass transfer heat transfer shear stresses surface chemistry surface morphology cohesion: rheology, materials 7
8 Sinner s Circle The interaction of key process parameters 8
9 Sinner-gy fluid mechanics normal stresses liquid adhesion shear stresses etc. surface chemistry rheology 9
10 Sinner s circle is about cleaning rates Think of reaction kinetics dx dt k C Let X be the extent of cleaning t X k, 0 T, V ph C dt 10
11 The big question: What is the reaction? There are many different s There are a number of cleaning mechanisms The mechanism determines the chemistry and forces to use 11

20 The science behind the matrix Mobile Immobile Dissolution solution Erosion solution Thermodynamics Mass transfer Cohesion Shear stress Roll-up solution Peeling solution Wetting Buoyancy Adhesion Shear and normal stress 20
21 Forces Roll-up, erosion and peeling mechanisms all require understanding of the forces imposed on layers the rheology chemistry Self-weight/buoyancy Fluid shear Normal forces t M g 21
22 Doing cleaning.. 1. Identify 2. Characterise 3. Identify chemistry to use 4. Apply agents 22
23 How do you apply your cleaning agent? Aqueous cleaning solutions or solvents Mode 1 duct flows Mode 2 free surface flows 23
24 Mode 1 duct flows The flow rate sets the local velocity Scale up lab/trial results if we know the mechanism (key parameters) Guidelines on mean flow velocities: main uncertainty is chemistry/rheology fluid mechanics normal stresses liquid adhesion shear stresses surface chemistry rheology 24
25 Mode 1 challenges and opportunities Monitoring Optimisation minimising resources Clever flows Overall cleaning rate /g m -2 s -1 Overall cleaning rate g/m 2 s flow pulsing steady flow Protein Coverage coverage /g 25 m g/m
