Collo's liquid fingerprint technology offers an easy way to optimise production and cut product losses.

Rising costs from inflation and increased focus on reducing carbon dioxide emissions make product loss management more important than ever in dairy plants. One major reason these losses occur is because timings or other process parameters are set incorrectly, causing a lot of valuable dairy product to be unnecessarily washed out together with the wastewater. Collo’s unique liquid fingerprint technology addresses this problem by detecting any type of liquid in the pipes in real-time, offering an easy way to optimise production and cut product losses.

 

The rising costs of raw milk, electricity and other expenses are driving dairy plants to put more focus on reducing milk loss. The cost of raw milk risen by 64% in two years in the EU region, and in some countries significantly more. With thin profit margins, it is a strategic imperative for many plants to minimise product loss. At the same time, there is global pressure to reduce the CO2 footprint of dairy production, and here milk loss at the plant plays a key role.


The scale of the problem is huge. Considering that the EU alone had more than 12.000 milk processing and production sites handling over 161 million tons of raw milk in 2021, significant volumes of milk could be saved, translating into greatly reduced carbon footprints for dairies across the EU by prioritising reductions in production losses.

 

“But to be able to minimise wasting valuable milk products, it is essential to know where in the process the leak happens,” says Mikko Tielinen, Head of Sales at ColloidTek. “With conventional methods it is hard to meet that goal, which often results in milk products being unnecessarily flushed out with the wastewater. When a leakage then shows in the form of excess organic waste in the effluent, it is extremely difficult to determine where it is coming from.”

What makes Collo’s liquid fingerprint technology unique is its accuracy and ability to detect any type of dairy product in real-time – be it raw milk, protein concentrate, cream in water or other – even CIP chemicals.


Millions of euros down the drain

For a typical dairy plant with an intake of around 250 million litres of milk per year, a loss of just 1% of the raw material corresponds to literally throwing about one million euros down the drain.

 

Mikko Tielinen points out that current solutions are insufficient for addressing the problem. Flow rate timing is very inaccurate, and traditional sensors are unreliable and imprecise, with fouling and creep being major issues. As several types of traditional sensors are needed to detect different types of liquids, such as whey, cream, and cleaning chemicals, the optimisation systems become complicated and expensive to manage.

 

“Our solution, on the other hand, offers an easy and very accurate way to detect where exactly in the process the leakage is,” Tielinen says. “It measures the exact real-time liquid fingerprint at any desired point in the process with a single EMF-sensor. Combined with machine learning, our solution ensures that the process stays optimised and easily monitored through our cloud solution.”

Collo Analyzer helps you detect leaks to minimize product loss. In Collo’s solution, the analyzers are installed to key locations in all process stages. With continuous monitoring across the plant, the sensors can detect the source of leaks in real-time.

 

Addresses problems at the source

Usually, product losses in the process are noticed when there is an excess of organic material in the effluent. This can also be a sign of problems in the production, however, measuring just the effluent does not tell why, and from where too much milk product is getting flushed out with the wastewater.

 

“As our technology can supervise all the draining points in real-time, it can keep track of the liquids in the pipes and show exactly where the leakage is,” Mikko Tielinen says. “This makes it possible to address the problem at the point of origin, saving huge amounts of milk and money.”

 

In addition to directly improving the profitability of a dairy plant, reducing the milk waste also lowers the cost of wastewater treatment and helps dairies to achieve their environmental goals.

 

“Most of the carbon dioxide generated in a dairy production originates from the stages before the milk even arrives at the dairy,” Tielinen says. “That is why it is essential to not waste valuable milk in the dairies’ processing operations. If milk-based products are lost in a dairy, a replacement amount of milk will have to be produced and transported to the dairy, which will produce even more carbon dioxide emissions.”
