In food and beverage production, every litre matters. Many plants already use optical sensors to improve Clean-in-Place, or CIP, processes. However, valuable product is still often lost during product-to-water, water-to-product, and product-to-product transitions.
The reason is simple: many process lines still rely on time-based or volume-based phase separation. These methods are safe, but not always accurate. If the transition is delayed, good product may be sent to drain. If the transition is too short, water or another product may enter the final product stream.
Real-time optical measurement gives production teams a clearer view of what is actually happening inside the pipe. Instead of estimating the changeover point, the process can be controlled based on the real composition of the liquid.
The hidden cost of the mixed phase
During process transitions, operators must manage the mixed phase between two liquids. This can happen when pushing product with water, changing from one recipe to another, or preparing a line for packaging.
Without real-time visibility, automation systems often use conservative delays to avoid contamination or dilution. These delays may seem small, but they can create continuous losses over time. Product loss, higher wastewater volumes, increased effluent treatment costs, and unnecessary reprocessing can all affect profitability.
For dairy processors, breweries, beverage producers, and other hygienic process industries, even small improvements in phase separation can make a measurable difference.
How real-time turbidity measurement improves phase separation
Optical turbidity measurement helps detect changes in liquid properties directly in the process line. This makes it possible to identify the interface between product and water, or between two different products, much more accurately than with a fixed timer.
In practice, this supports several key production stages:
Product-to-water and water-to-product transitions
Optical sensors detect when the product phase changes to water, or when water changes back to product. This allows valves to switch at the right moment, helping plants recover more usable product and reduce unnecessary losses to drain.
Product-to-product changeovers
In plants running multiple recipes, such as dairy, brewery, or beverage production, optical measurement helps detect changes between products. This supports faster changeovers, reduces cross-contamination risk, and improves process consistency.
Packing line protection
Before filling, it is essential that only the correct product reaches the packaging line. Real-time measurement helps prevent diluted or mixed product from entering the filling machine, supporting consistent quality and reducing the risk of customer complaints.
Beyond CIP optimisation
CIP optimisation is an important application for optical sensors, but it is not the only one. The same measurement principle can support product recovery, phase separation, quality control, wastewater monitoring, and process efficiency.
By replacing guesswork with real-time data, food and beverage manufacturers can improve both sustainability and profitability. Less product is wasted, less water is sent to wastewater treatment, and production teams gain better control over every transition.
Look Closer™ with Satron LUMINA™
The Satron LUMINA™ range of optical transmitters is designed for demanding food and beverage applications where reliable, real-time process information is essential.
LUMINA™ sensors help production and automation teams detect changes in liquid properties and optimise phase separation based on actual process conditions. The sensors are available with several hygienic process connection options, making them suitable for a wide range of food and beverage applications. Combined with their robust hygienic design, maintenance-free operation, and real-time measurement capabilities, they help manufacturers achieve reliable process control, maximum uptime, and consistent product quality.
A smarter way to reduce product loss
Reducing product loss is not only a sustainability goal. It is a direct driver of operational performance.
With real-time optical measurement, food and beverage manufacturers can move from estimated transitions to accurate, data-based control. The result is better product recovery, improved quality, lower wastewater load, and more efficient production.
Satron helps food and beverage producers look closer at their process and find value where it is often lost, in the transition.
