Optimizing liquid packaging, filling operations with inline viscosity management

Key advantages of viscosity management in liquid products filling lines:

  • Accurate and efficient packaging line operations – significant savings in material costs
  • Seamless product change-over: agility in dealing with different and new product variants and product provenance
  • Compliance with regulations
  • Optimizing CIP systems

Introduction

Packaging liquid, liquid with solid chunks, and gel like products consists of the packaging materials and packaging machines like filling lines. It includes rigid packaging formats such as bottles & containers and flexible packaging formats such as films, stand-up pouches, squeezable tubes, cartons, and bag-on-box. In many industries, packaging processes are automated using filling lines.

Liquid packaging application areas span multiple industries – food and beverage, cosmetics, household products, chemicals, medicines, FMCG products. Some examples by industry are:

  • Food and Beverages: Sauces, Dairy products, juice, carbonated beverages, soups, coffee/tea, yogurt, milk, ice-cream, gelatin desserts, honey, jelly, syrups, aseptic food, butter, ghee, beer etc.
  • Cosmetics: Creams, lotions, shampoos, facial, hair oils, sunscreens
  • Medicines: Syrups, Drops, ointments
  • FMCG: Toothpastes, sanitizers, handwashing liquids, dish washing liquids, liquid detergents
  • Chemicals: Industrial, water treatment, adhesives, mining, catalyst, lab and other application uses.

Mechanisms for filling/packaging

One of the keys to a successful liquid packaging line is efficiency. For optimizing the efficiency of a packaging line, there are multiple factors to consider. It includes viscosity of the liquid, product characteristics, specific product challenges, ease of cleaning, accuracy, ease of flexibility and changeover, and using a reliable machine vendor.

All liquids flow differently. Understanding this is of utmost importance while designing a filling machine. Viscosity is the property that gives insights into the liquid’s flow behaviour. Therefore, it’s crucial to take note of the viscosity of the product you are handling. Filling methods differ in cost, accuracy, speed and hygiene. Not all methods are suitable for all liquids, for beverages need particular hygiene, expensive cosmetics require special precision, while engine oil has a different flow characteristic to, say, mineral water. A free-flowing product such as water that is low in viscosity will flow well through a gravity filler. This is because this type of machine relies on the power of gravity to push the product through.

Some products that are higher in viscosity will need assistance to be filled into the packaging. Lotions and other high viscosity liquids work well with piston fillers and pump fillers. Piston fillers have a versatile ability to handle liquids from aerated products to icings and sauces. Pump fillers work well with liquids of all viscosities and offer variety when it comes to the pump chosen. Pump fillers can utilize progressive cavity pumps, gear pumps, lube pumps, and various valves and fittings to meet the project’s needs.

Technology for the Fully Automated Filling of Liquids

There are various principles of measuring fill quantities of liquids in industrial processes. All principles have some things in common: liquids never flow through the pipes of the bottling machine at a uniform pressure. Density can fluctuate due to air bubbles in the liquid and changes in the temperature or recipe. Therefore, the correct fill quantity cannot be determined simply on the basis of time.

  • Gravimetric filling using load cells
  • Measurement with level sensors
  • Volume measurement
  • Mass flow measurement

The various measurement methods achieve different filling speeds. When filling with a level sensor, a bottle can be filled in two to four seconds. With weighing technology or mass flow measurement, it takes around five seconds to fill a bottle. Flow rate measurement suffers the largest fluctuation in filling speed, with the time varying between two and five seconds.

Why is viscosity important?

“Viscosity is the Name of the Game in Liquid Packaging”

Regardless of the automated filling technology deployed in the factory, engineers are keen on staying in control of the viscosity of the liquid product. Viscosity is an essential factor to consider when it comes to liquid packaging since it affects the speed with which the liquid travels through the pipe, sets, and dries, and is dispensed into the packaging. That’s why it is important measure viscosity accurately for proper packaging. Viscosity will also determine the kind of product filler. It will have to supply enough force to encourage flow, but not so much that there will be overfill.

What makes viscosity automation and control so important in building an efficient packaging line for liquid products?

One of the first aspects of a packaging line that a business needs to consider is the viscosity of the liquid going through the filling and packaging processes. The thickness of the liquid will be a huge determinant when it comes to selecting the right machinery to purchase and install. If equipment is used for the wrong viscosity level, it could significantly hinder productivity, and breakdowns are more likely to occur. Consider whether the liquid is water-thin, thicker or highly viscous, which can be determined using a viscosity chart when selecting machinery.

There are several advantages of inline, real-time viscosity monitoring and control in packaging line for fluid/liquid products:

Accurate and efficient packaging line operations – significant savings in material costs. Viscosity control makes liquid packaging lines more ‘accurate’ by ensuring consistent product and thus enables tighter control for right level of product to be dispensed. Viscosity quality control in production and transportation stages, preceding the filling operations can ensure that the exact quantity of liquid is dispensed, with minimal amount of process variabilities which can possibly arise from the packaging line equipment such as nozzles and valves.  This results in significant material savings for the company, considering the scale of operations.

In order to comply with regulations penalizing underfilling, during production manufacturers often exceed the minimum quantity in packaging. However, such safety overfilling can be costly. For example, a mid sized milk producer fills around 100,000 bottles of coconut milk per day. By reducing the overfill in individual bottles by a few grams, the company could potentially save several million euros a year. Manufacturers of complete bottling plants should therefore offer systems that measure the fill quantities with high precision and keep overfilling to an absolute minimum.

Seamless product change-over: agility in dealing with different and new product variants and product provenance. Factory engineers get a more accurate picture of how the new formulations or recipe changes will react and how they might need to adjust current systems and control parameters. Real-time monitoring facilitates transition of a batch-based process to continuous operation, saving significant operational and capital costs through re-use of the same lines for multiple products. The packaging line engineers can respond quickly to ever-changing consumer demands, optimise output and reduce system costs.

Viscosity data helps the packaging line engineers adjust the parameters to ensure they maintain tight control of the dispensing process unaffected by change in product properties, especially the flowability which is dependent on the viscosity. Additionally, the decisions of adapting the machine parameters and variables (nozzles, pumps, valves controls) can be reliably driven and automated by the viscosity data, hence ensuring changeover time is restricted to the minimum.

Compliance with regulations. When it comes to food and beverage products, quality, safety and confidence are absolutely critical. Accuracy and repeatability of the dispensing process needs to be tightly controlled, since EU, WHO norms and other GMP guidelines state permissible tolerance levels depending on product/industry types. The challenge for all these processes is the same: the packaging must contain the stated quantity of product. If the fill quantity in bottles is too low, for example, this contravenes EU Pre-packaging Directive 76/211/EEC and German Pre-packaged Product Act (§22 FPackV). These stipulate the percentage by which a production batch may fall short of the specified minimum fill quantity. Here, “misconduct” can lead to penalties that include the shutdown of production.

This means viscosity automation is critical to ensure the filling process stays efficient to avert risks of scraps, rejects and penalties – which can be significantly high in continuous liquid filling factories packaging tonnes of materials every hour!

Other Considerations for efficiency of a liquid packaging line

Ease of cleaning. Another important aspect is the ability to clean the equipment easily and without issue. The easier machinery is to clean, the less time is needed to spend cleaning parts and machines, and the faster it can be up and running again. Machinery that’s easy to disassemble will help keep the cleaning process efficient. One example of this is for the customer to purchase equipment that offers either a manual or automatic clean in place (CIP), which is the most efficient way to clean a filler. CIP will cycle the cleaning solution through the machine to ensure that all wetted parts are clean.

Ease of flexibility, changeover and scalability. The machinery’s ease of changeover and flexibility are also integral to an efficient packaging system. This means that equipment should be able to accommodate multiple types of containers or liquids without the need to change parts. Some manufacturers have machinery that’s capable of handling multiple bottle sizes through the use of a single piece of equipment as long as the liquids’ viscosity is consistent. Machinery should also be easy to upgrade, which is particularly important as business grows.

The broad and significant factors which make viscosity management important in virtually every filling application:

  1. Quality: Viscosity monitoring of the liquid product in the processing and transportation stages preceding the filling operation can ensure that prior to filling, the product quality/consistency is adequate.
  2. Repeatability across batches: To ensure consistency from batch to batch, and to maintain a consistent level/weight, viscosity control is essential.
  3. Reduced waste and cost savings: Accurate filling operations means that the exact amount of product is delivered during packaging, saving tonnes of extra materials which could potentially be additionally used up otherwise. It also means reduced scraps and rejects, even in the tightest regulations, thus minimizing costs.
  4. Efficiency: Hassle free, real time monitoring of viscosity can save a lot of time and effort which is involved in offline analysis of the sample and making process decisions based on that analysis.
  5. Environment: Viscosity automation can optimize the CIP/SIP processes. Lowering the amount of use of cleaning fluids/materials is good for the environment.
  6. Smart factory – digitalization and automation benefits: The process data acquired by the sensors can be used in multitude of other ways – machine maintenance scheduling, QC diagnosis, root cause analysis, information exchange across facilities for decentralizing decisions and much more.  The ability to load different jobs/models for different fluids by using viscosity information transforms into benefits of paramount importance, enabling companies reap benefits of Industry 4.0 and automation technologies. They become more adaptable to ever changing consumer needs. Learn more using the link below.

Leak Detection and Power Consumption Optimization with continuous online viscosity measurements

Viscosity is one of the crucial fluid properties whose measurement can affect the accuracy and the performance of a Computational Pipeline Monitoring (CPM) system, especially those CPM systems that rely upon a Real-Time Transient Model(RTTM/E-RTTM) based solution to deliver leak alerts, leak rates and leak positions.

Leak Detection System (Real Time Transient Model based methods) significantly benefit from online viscosity monitoring devices. Viscosity data enables a more accurate calculation of pressure profiles and fluid property tracking. This is particularly true for factories which manage different product lines, where the fluid properties can significantly differ from one run to another. Continuous viscosity data tracking can also aid in the improvement of pump selection for optimized performance and management of power consumption. Similarly, in blending operations, having online viscosity measurement will enhance system operations by providing more up-to-date and accurate information for the calculation of pump power consumption.

Viscosity measurement and process challenges

Engineers and plant operators in packaging lines realize the need to make viscosity measurements and to intervene through appropriate corrective actions for achieving high-quality and consistent, predictable flowability of the liquid/semi-liquid product. However, making these measurements have challenged them over the years.

Offline grab-samples are simply unreliable and not suited for liquid packaging operations

Monitoring the viscosity of a fluid in a process often means taking a sample of the fluid from a tank or pipeline, and bringing the sample to a laboratory where its flow and rheological properties are measured on a laboratory viscometer or rheometer. Based on the findings, the process operator must be informed whether the fluid is at the desired viscosity, or if further action is required then new measurements must be made after intervention. This system is called off-line or manual control, with several obvious disadvantages – it is time-consuming and often inaccurate even with experienced operators. Most often the results are too late to save a batch.

The alternative is to use an in-line viscometer that will continuously monitor the viscosity of the process fluid throughout the process. This instrument gives an output signal which, if displayed, provides the operator with the necessary information to control the process. Alternatively, viscometer outputs are connected to a PLC (Programmable Logic controller) / DCS (Digital Control System) for automatic process control.

Issues with conventional viscometers for inline installation

Traditional process viscometers encounter problems related to the fluid flow in pipeline and tank-mixing installations. In general, these older generation viscometers do not function properly in turbulent flow. Rotational instruments will only operate up to a certain maximum flow rate. The flow has to be controlled for pressure drop viscometers. Flow related problems for these types are avoided by installing the viscometer on by-pass line and conditioning the sample flow to suit the instrument. Instrument response time is then related to the flow conditions, as an adequate sample renewal rate is required for effective control. Furthermore, instruments used in a process environment have to be robust and able to resist any corrosive materials that they may encounter, especially during cleaning.

Inline probe-style density meters have an edge in weight-based automated filling

For precise automated filling (for example – Volumetric method), it can be especially important to monitor and control density. Density can fluctuate due to air bubbles in the liquid and changes in the temperature or recipe.

Coriolis flow meters give mass flow measurements but they have certain disadvantages such as:

  • Time consuming calibration procedures and difficult installation
  • Difficulty in cleaning: Coriolis flow meters are difficult to clean, especially when the fluid has considerable solids content. It makes them unsuitable to meet the hygienic standards inside factories.
  • Longer filling times: With weighing technology or mass flow measurement, it takes around five seconds to fill a bottle. Flow rate measurement suffers the largest fluctuation in filling speed, with the time varying between two and five seconds.

On the other hand, Rheonics SRD are designed and built for the easiest integration in a continuous production environment. They have no special chambers and can be easily removed for cleaning or inspection. SRD probes are hermetically sealed for Clean-in-place (CIP) and supports high pressure wash with IP69K M12 connectors. SRD is a unique product that replaces three different instruments for viscosity, density and temperature measurements.
