Brewing & Distilling Industry
Quality Control with FOOD Grade Mixers
The brewing process uses malted barley and/or cereals, unmalted grains and/or sugar/corn syrups (adjuncts), hops, water, and yeast to produce beer. Most brewers use malted barley as their principal raw material. Optimizing distillery processes often means balancing energy usage with quality. Distillery processes are energy intensive, especially in the brewhouses where mashing and wort boiling are the main heat consuming sources with high fuel consumption. Water consumption is another factor as it’s a substantial ingredient of beer, composing of 90-95 percent of beer or other spirits and is involved in almost every process.
Depending on the location of the brewery and incoming water quality, water is usually pre-treated with a reverse osmosis carbon filtration or other type of filtering system. The intense cleaning processes result in high variability in the acidity of the wastewater. Materials of construction must address this.Because of the above factors, processes need to be constantly optimized to reduce energy consumption, decrease ingredient usage and water waste all while still maintaining the consistency in alcohol percentage, flavours, taste and colors of the final product. These quality control steps begin with precise mixing. When mixers are correctly matched to tank size and ingredient mixture, time needed for complete uniformity can be significantly minimized during production, decreasing output wastage as well.
For example, shear control can directly affect that taste in large Mash batch mixing. Mixers with impellers of the axial flow turbine can are the beginning step of providing a low / controlled amount of shear. Providing lower and controlled shear is preferred in to maintain the delicate natural ingredients that attribute to the flavoring in wine, beer or specialty liquors. Using our approach to designing mixers the process will have greater control. For example, in large mash mixers a consequence to poor mixing can be shear damage from aggressive mixer designs and/or the misuse of baffles in mash mixers. This has two exceptions; When preparing grains or heavy starches (viscosities cps) for the mash tun, higher speed mixing with pitch-blade impellers helps ensure good wetting and sugar separation and extraction from the mixture – a high pumping action for full and rapid tank turnovers. Second, mixer speeds are increased after steeping to ensure good temperature distribution throughout the tank.
When mash mixers are used during mashing there is always a separate wort separation device, be it a lauter tun or a mash filter. The primary reason for stirring the mash is to provide uniformity when heating the mash. Brewers who employ step mashing, sometimes referred to as upward infusion mashing, double mashing and decoction mashing all use mash mixers.
Dynamix configures mixers that can withstand high and low temperature changes registered throughout the distillery processes and also address the problem of shear damage by using low shear mash agitators designed to pump the mash down to the center of the mash mixer bottom. Mixers are also used in fermentation tanks stimulate a desired yeast suspension at all times and prevents sedimentation of the yeast. Mixers in fermentation tanks increase fermentation capacity, suspends solids quickly, stabilizes emulsions, minimizes stress on the yeast enzymes and conserves more energy.
Brewery & Distillery Mixers
CONFIGURED FOR YOUR SPIRIT PROCESS
Each distillery and brewery plant uses their own starches and sugar based ingredients ranging from low to high product viscosities, solid suspension parameters and unique tank, still or vat dimensions for each application. We provide highly configurable mixers with explosion-proof motors, either top or side entry that can be equipped with optional dry running mechanical seals to eliminate product contamination and that perform at high-to-low temperatures and pressures.
The result? Uniformity, right when you need it.
