How motors and variable speed drives can help food and beverage plants reach sustainability goals

Strong demand for convenient, healthier foods and beverages – produced and packaged in the most environmentally friendly way possible – is placing critical importance on sustainability at every stage of the value chain. Variable speed drives (VSDs) and high-efficiency motors can help the industry address two key sustainability challenges – energy efficiency and water conservation.







Increasing energy efficiency


In a world where corporate responsibility includes environmental consciousness, focusing on energy efficiency can help companies position themselves in a more favourable light with their stakeholders. At the same time, saving energy also contributes directly to greater profitability and meeting minimum energy efficiency legislation.




The first step is to pinpoint the most significant sources of energy usage. Look at where, when, and how much energy is used in various applications. Electric motors usually make up the bulk of a plant’s energy consumption. The good news is that there is a significant opportunity to reduce electricity usage by upgrading from inefficient motors to ultra-premium motors, like IE5 synchronous reluctance motors (SynRM).




Adding variable speed drives can also have a significant impact on energy savings. Companies can even use ABB’s EnergySave calculator to explore how much energy and money they could save by installing drives.  Traditionally, the majority of motors in factories run at full speed when they don’t always need to, wasting energy. Using VSDs allows for more control over a motor and adjusts the speed or torque according to the actual needs. This means the motor only draws the power needed to perform the task, cutting waste. Replacing throttle valves with VSDs on pump control is another way to save energy.  Adding VSDs can unlock energy savings to its full potential – with a strong chance to reduce energy consumption between 20 to 60 percent. 


添加变频器也会对节能产生重大影响。企业可以使用ABB的EnergySave 计算器来计算安装变频器后可以节约多少的能量和成本。传统意义上,工厂中大多数电机在不需要时仍会全速运转,这也导致了能源的浪费。使用变频器可以更好地控制电机,并根据实际需求调整转速或转矩。这意味着电机只在需要的时候工作,这样可以减少能源浪费。在水泵应用控制上用变频器代替节流阀是另一种节省能源的方法。添加变频器可以充分释放节能的潜力,极有可能帮助企业降低20%到60%的能耗。





ABB Ability Smart Sensors for either pumps and/ or motors can help spot energy saving opportunities. Data collected from the smart sensors, combined with information collected from VSDs' inbuilt sensors and loggers, can be collated, stored, and further accessed via cloud technology. The ability to gather and analyse this data can reveal information that can be used to make performance improvements that will increase efficiency.


适用于泵和电机的ABB Ability智能传感器可以帮助客户发现潜在的节能机会。智能传感器收集的数据,和变频器内置传感器和记录器收集的信息,可以通过云技术进行整理,储存和进一步访问。收集和分析数据的能力可以帮助企业改进设备性能,从而提高生产效率。




Optimizing water usage



High-pressure cleaning consumes vast quantities of water. Activities such as cutting, dicing, slicing, and filleting also generate a large volume of wastewater. Minimizing the water used for process equipment and pipeline cleaning presents another challenge for food manufacturers.





One solution is to implement efficient pumping by using VSD pump controls to help optimize water usage. These controls offer several critical software functions such as regulating the pressure and flow rate for pipe clean and fill functions in Clean-In-Place (CIP) equipment. This reduces the cleaning time, resulting in less water and cleaning materials being used. Anti-cavitation software can also detect and prevent cavitation to ensure the optimal flow of water throughout the plant an extending the pump’s lifetime. Another way to save water is to choose products that are very easy to clean – taking less time and requiring less water such as hygienic, stainless-steel washdown motors designed with smooth, crevice-free surfaces.


一种解决方案是通过使用变频器泵控制来优化用水,实现高效泵送。这些控件提供了一些重要的软件功能,例如调节就地清洁(CIP)设备中管道清洁和填充功能的压力和流速。 该方案减少了清洁时间,从而减少了水资源和清洁材料的使用。防气蚀软件还可以检测和防止气蚀,以确保整个工厂中最佳的水流量,从而延长了泵的使用寿命。节约用水的另外一种方案是选择易于清洁的产品,这意味着企业只需要花费更少的时间和水量来进行设备清洁。例如设计成具有光滑无裂缝表面的卫生型不锈钢冲洗电机。


Sustainability is everyone’s responsibility



Running a more sustainable, energy-efficient food and beverage manufacturing plant takes work and needs both clear decisions from senior management and commitment from all levels of the organization. By prioritizing energy and water conservation, identifying the areas that need the most attention, and committing to energy and water saving initiatives, manufacturers can have a positive impact on sustainability, as well as reducing costs.
