The Role in Food Production
They play a vital role for many food producers by providing a controlled environment for the fermentation process. Fermentation is a process where microorganisms like bacteria or yeast interact with ingredients like fruits, vegetables, grains or dairy to produce everything from bread, wine and beer to kimchi, sauerkraut and yogurt. They allow producers to carefully control various factors like temperature, pH level, oxygen levels and mixing to achieve the desired results.
For example, many dairy producers use large Fermenter steel fermentation tanks that allow them to precisely control the fermentation of milk into yogurt. They maintain an optimal temperature around 110-115°F for the lactic acid bacteria to adequately multiply and cause milk to thicken into yogurt within around 4-7 hours. Proper agitation during this process results in a creamy consistency.
In the brewing industry, fermenters are integral for transforming wort (unfermented beer) into actual beer. Large cylindrical tanks controlled at around 60-70°F allow yeast to consume the sugars in wort and produce the desired alcoholic beverages along with other flavors over the course of 1-3 weeks. Proper aeration and mixing is important to facilitate the fermentation process.
Economic Benefits of Large-Scale Fermenters
Larger food producers have benefited tremendously from investments in large industrial scale that can process massive volumes of ingredients on a continuous basis. This allows for significant economies of scale that reduce production costs.
For example, a large dairy may have fermenters that can hold up to 50,000 gallons of milk or more at once. Running almost non-stop, such can produce truckloads of yogurt daily in an extremely cost-effective manner compared to smaller batches.
Similarly, major breweries rely on towering cylindrical fermentation tanks that can hold hundreds of thousands of gallons each. With advanced controls, these automated systems can maintain a perpetual fermentation process to pump out railcars full of beer. The savings in labor and overall efficiency allows them to profitably sell at lower price points than craft brewers.
Flexible Fermenters for Variety
While large standardized types are great for mass production, some industries require versatility. Breweries specializing in small batch beers may utilize modular designed for quick changes in recipe and flavor profiles.
Wineries as well have adopted specialized fermentation systems tailored for individual grape varietals and styles. These can be reconfigured efficiently to shift between white, red or sparkling wines. Temperature controls may also be more granular.
Even for large scale yogurts, ice creams or cheese, producers have implemented networked fermentation suites with standardized connections but removable internal components. This allows continuous fermentation while seamlessly switching between different cultures, probiotics or specific milk/cream batches with minimal downtime.
Sustainable Designs
As environmental regulations tighten, new designs increasingly focus on sustainability. Many utilize cogeneration systems that capture waste heat from fermentation to help power other plant operations or facilities.
Advanced controls also optimize aspects like aeration to reduce energy costs. Systems with modular tanks allow running just the optimal footprint needed rather than vacant space. More feature CIP (clean-in-place) fittings eliminating time-consuming manual cleaning.
With food tech innovation, new formats include single-use flexible bags for applications like natural health beverages that eliminate vessel cleaning completely. Overall, sustainable features lower operating expenses while reducing environmental footprint.
Future of Fermentation Technology
Ongoing R&D is expanding fermentation applications into novel areas. Rather than just converting compounds, fermenters show promise synthesizing materials like bio-plastics, fabrics or even cultured meat directly.
Advanced sensors now monitor nearly every parameter in real-time for predictive maintenance and process control. Analytics reveal inefficiencies to further automate operations. Some operations even deploy automated robots for tasks like sample collection.
Blockchain integration ties together global supply chains by digitally tracing the entire fermentation history and certifying quality. Soon, Internet of Things (IoT) sensors embedded in fermenters themselves may proactively detect and remedy issues like temperature deviations.
As fermentation expertise converges with various sciences, the industrial applications and economic potential continue to grow exponentially. They will remain a crucial production technology transforming the global food and beverage landscape for decades ahead.
