Optimise fermentation in alcoholic beverage manufacturing through proper valve selection

February 2021 Valves, Actuators & Pump Control

The alcohol business is booming. The explosion of craft beers, demand for new wine blends and rise of international distilleries means consumers have more choices than ever. Whether you’re a small-town brewer, boutique winemaker or global brand, you need to make sure your products maintain the same high levels of quality and taste to keep up with demand, despite such variability.

The key lies in the fermentation process, which requires precise temperature control to ensure quality and consistency across various beverage styles and flavours. Optimum temperature control requires the right valve system to control heating and cooling parameters. Too often, valves experience short service lives and other performance issues that can cause temperature fluctuations – compromising beverage quality and costing precious time and money.

The challenges of upgrading fermentation systems

Alcoholic beverage producers typically control tank temperatures using glycol or ammonia systems. A common medium used today is propylene glycol, which flows through thermal jackets surrounding the fermentation tanks. In a closed circuit, the glycol is pumped through a chiller, where it is cooled, and then flows back through the jackets. Not only does temperature affect the speed of the fermentation process, but it also affects the taste and quality of the final beverage.

Because fermentation is such a vital process, it is no surprise beverage makers are increasingly looking to install or upgrade their tank cooling and heating systems. But these modifications do not come cheap, nor are they without their challenges. Many facilities, particularly smaller operations, have limited physical space. As a result, tank systems need to be positioned as close as possible to each other to maximise floor space and remain accessible during maintenance – making innovative yet costly tank designs a necessity. Other challenges include the high cost of energy, lengthy piping processes and potentially unreliable yields.

How choosing the right valve can help

In addition to ensuring precise temperature control, proper valve selection can address the challenges associated with installing, maintaining and upgrading fermentation heating and cooling systems, saving equipment space, conserving energy and optimising productivity. Depending on the system, it is also important to select valves that are rated to handle glycol or ammonia.

Whether you’re spending too much time on piping or you’re a startup operation with limited resources and space, Emerson can help you select the right fluid automation product to meet your unique needs. Choose from the following valve solutions, all of which are suitable for systems using glycol or ammonia:

• Two-way valves: two-way valves are a traditional, tried-and-true valve type for fermentation heating and cooling systems. These high-flow solenoid valves come in a range of pressure ratings, sizes and resilient materials like brass or stainless steel, providing long service life and low internal leakage.

• Solenoid valves: these include several electrical enhancements to achieve energy savings and longer service life. Look for valves that incorporate power management circuits, as well as electrical surge suppression to both the solenoid and electronic controls.

• Angle seat body valves: air-operated, direct-acting angle body seat valves are ideal for aggressive and high-viscosity fluids. Many models feature a straight-through design and wide range of advanced options, including a signalling box, compact positioner for proportional control, and stroke limiter. These valves are the preferred alternative to diaphragm and ball valves.

Controlling temperature automatically

In addition to proper valve selection, it is important to consider automating fermentation heating and cooling systems to achieve even greater thermal precision. For example, the G3 electronic fieldbus platform makes this process quick, simple and painless. G3 integrates communication interfaces and I/O capabilities into pneumatic valve manifolds, allowing the PLC to turn valves on and off, as well as channel temperature data from resistance temperature detector (RTD) sensors. Compact and modular, G3 includes a range of innovative features to enhance fermentation operations, including a graphics display for easy commissioning and fault diagnosis, as well as compatibility with a range of industrial communication protocols, including Ethernet, Profinet, DeviceNet and many others.

Valves, along with the G3 automation platform, provide a single solution that overcomes many of the challenges preventing alcoholic beverage makers from installing, expanding or upgrading their fermentation systems. In addition to saving space, conserving energy and improving critical uptime, this combination delivers the peace of mind that comes with knowing that all beverage products are achieving the highest levels of quality, consistency and taste.
