4 Dry Hopping with IMXD Alyce Hartvigsen

5 Problem: Efficient Dry Hopping Alfa Laval Slide 5

6 Problem: Dry Hopping Process Issues Slugs of hop solids Blockages of lines, HEX, filters Carry-over of solids Product losses Unplanned down-time/outages Increased waste streams Alfa Laval

7 Solution: Dynamic Dry Hopping More effective dispersion of hops into beer Faster and more efficient aroma/flavour extraction Shorter hop residence times in beer Homogenization of hop particles during transfer Efficient separation of hops from beer Reduction of beer losses Reduction of process times Alfa Laval Slide 7

8 Iso-Mix External Drive (IMXD) Motor-driven Rotary Jet Mixer Tolerates high particulate loads Flexible hops introduction method Fast dispersion and flavour extraction Homogenization of feed to centrifuge Reduced hop residence time Reduced beer losses More efficient aroma/flavour extraction Alfa Laval Slide 8

22 Center to Center Summary Smooth acceleration of the feed minimizes yeast micronization (particlle splitting) increasing exponentially sedimentation velocity. No product Oxidation, No aroma / hop oil stripping and virtually No Oxigen Pick up. Significant reduction in power consumption. Up to 70% reduction compared to traditional top feed bowl design. Bowl design capable to operate in a wide range of flows without any further adjustment.

23 edrive (patented innovation) Mechanical simplicity: rotor is an integral part of the bowl spindle. Fewer parts: No motor bearings, motor shaft or flat belts. Less moving parts, less energy loss, less heat generation, less need for cooling. Extended service intervals.

33 UniDiscs Boosting Separation Performance to new boundaries

34 UniDiscs Theory Lambda Flow pattern between rotating discs. Radial-tangential velocities Substancial efficiency optimisation possible by reducing lambda factor. h sin

35 UniDiscs Technology Radical production technology innovation. No welding. Micro-caulks as distance/spacers between discs Discs are thinner and caulk height lower. Disc stack can hold more discs increasing efficiency.

36 UniDiscs Benefits Equidistant space between discs. Separation area is used more efficienctly. Optimal disc stack flow pattern. Significant improvement of Flow between discs. No maldistribution (unequal resistances from flow) which greately improves separation efficiency. Better cleanability. Formed from one single element. Less risk of contamination. 30% Flowrate increase with equivalent separation performance.

37 Top Stream Improved yeast handling in disc stack centrifuges for breweries using continuous solids discharge design

38 Traditional Mechanical separation liquid/solids 5000 g Liquid Solids 0,5 mm Flow between the discs

39 Top Stream Process Continuous solids stream Clarified beer stream Conventional solids discharge stream Feed stream

40 Top Stream process flows Continuous Solids stream Clarified beer stream Intermittent solids discharge stream Feed stream

41 Top Stream: Continous Yeast flow in pipes over top disc Yeast concentrate flow velocity v G = d2 ( ρ p ρ l ) rω 2 18 μ Particle settling velocity ~ flow rate ~ (rotation speed) 2

42 Top Stream Technology Hermetic Separator with continous concentrate flow sectors over top disc Fully hermetic design. No Oxygen pick up Hybrid separator. It can operate in continious discharge mode or intermittent discharge. Higher solids handling capacity than conventional self cleaning separators. Increase of beer yields. Beer recovery out of tank bottoms in continous mode. Minimum temperature pick up. No need of beer recirculation. Absence of low flow transitions. Centrifuge solids space is no longer a process constraint.

43 Top Stream Summary Not limited by solids content at the inlet. Bowl solids space is not longer a limitation to reach high flows with superior clarification performance High flexibility in feed concentrations of solids Full control characteristics of effluent and/or yeast concentration Low power consumption Yeast Outlet. It is not contaminated with operating/flushing water High yeast viability ( > 95% vital yeast viability) Air/foam free design allows a continuous measurement of solids concentration from outlet, for process control
