Laboratory beverage analysers

A complete range of modular laboratory sensors for beverage analysis

Modular Analysis for Brix, Diet, CO2 and O2 in Beverages

Maselli LP Series – At Line and Laboratory Beverage Analysers

The LP series is a complete range of optical sensors studied for the beer industry. We provide modules for the analysis of Refractive Index, Brix, % Diet , Carbon Dioxide, Oxygen PH and Conductivity.

The design is modular: the system can be composed of different analysis modules based on the applications needs and all connected by a single touch screen control panel that can also be connected to a network via Ethernet, and to a PC running our Multilab software for historical data collection.

The system is fully upgradable so the initial configuration can be expanded with additional analysis modules at any time. The system can be used as a bench top analyser, and a fully automatic sampler is available for sampling directly from beverage containers under pressure operating with cans, PET and Glass Bottles.

The system is user friendly and ergonomically designed skilled operators are not required to operate the system. The system is solid state optical technology which means the maintenance is minimal. The system is calibrated using certified solutions provided by Maselli.

Beverage Analysers

Maselli have been manufacturing liquid concentration analysers since 1948. Beverage manufacturers require analysis of many parameters during the beverage making process. From the measurement of the Syrup to the Final Beverage there are many applications for the Maselli Inline beverage analyser. With its unique modular construction the Beverage analyser can be designed with the required analysis modules to build a system meeting each applications needs. We provide modules for the analysis of Refractive Index, Brix, % Diet, Oxygen, Carbon Dioxide, PH and Conductivity.

The Maselli Beverage Analyser range IB07 is the only 100% inline system for continuous analysis of Soft Drink. Because the system was designed to be installed directly into the process line with Tri-Clamp fittings, there is no bypass loops or pumps. This design guarantees the best sanitary conditions eliminating any risk of contamination and this also reduces installation cost. 

The IB08 version of the beverage analyser can be located and connected directly to the line or the buffer tank. With this installation the analyser can be used at the beginning of production when the line is being primed. This saves time at start up and also allowing for the “pump and run” concept where the line can be started automatically. Time is money in beverage production so the Maselli range helps the decerning bottler get a fast return on investmnent.

The sensors connect directly to our user-friendly controllers that display results locally for the operator and can be connected to the plant control system via various output protocols including, Ethernet, Profibus and Devicenet for process control. The system is fully networkable and can be connected to a PC running our Multilab software for data collection. 

The Maselli system is a true inline beverage analyser providing rapid and reliable analysis results for process and quality control. The analysers are all solid state with no moving parts making them robust and practically maintenance free.

Laboratory beverage analyser questions answered by our experts

Laboratory beverage analysers are normally used to test carbonated and non carbonated beverages. These can be regular beverage products as well as dairy and plant based beverages. There are various types of laboratory beverage analysers and the selection of the appropriate system will be dependent upon the beverage portfolio the manufacturing facility produces..

A laboratory beverage analyser will consist of different modules, each module will make a specific analysis. These modules use various technologies depending upon the parameters to be measured.

Typical parameters are the sugar concentration or the Brix of the beverage for this analysis a refractometer or densitometer would be used.

Diet products using artificial sweeteners like Aspartame can be analysed using a high precision refractometer. This technology utilizes light to measure liquid concentration extremely precisely.

CO2 analysis is conducted in the laboratory using a pressure and temperature CO2 unit that will capture a fixed volume sample of beverage, agitate it to get equilibrium and then measure the pressure and temperature and using Henry’s law calculate the dissolved CO2.

Other common modules are dissolved Oxygen, PH and conductivity of the beverage.

Carbonated beverages need to be sampled under pressure so the integrity of the sample is not compromised. In order to sample from a packaged beverage an automatic sampler is used. The package (PET, Glass or Can) is inserted into the sampler. The sampler then pierces the cap of the bottle or the bottom of the can and removes the sample under pressure and presents that sample to the analysis modules.

If the product is non carbonated a sample pump can be used to extract the sample and present it to the analysis module, or samples can be placed in the analysers manually for some models.

An LED sends the light into a sapphire or balf prism. The prism is in contact with the liquid and the light from the LED is reflected back from the liquid surface like a mirror. The angle of the reflected light will change depending upon the liquid concentration. This reflected angle is called the angle of refraction. A refractometer uses a CCD to capture the returned light from the liquid. A shadow will be cast on the CCD and this shadow will move based on the angle of refraction. A refractometer uses the output from the CCD to precisely calculate the liquid concentration based upon the CCD image.

The Maselli Laboratory beverage analyser comes with a connection box. This connection box acts as the interface for the system's piping. 6mm PTFE tubing is used to plumb the system together via the connection box. Each port of the connection box is marked to make the installation very easy.

The laboratory beverage analyser can communicate using an Ethernet connection to a PC or network. The data is available in standard formats that are used in the beverage industry and the data can be easily exported into the clients software platform.

Yes the laboratory system is a primary standard and can be used to benchmark against the in line analysers used in the plant. Typically samples are taken close to the in line analyser measuring point, then analysed in the laboratory. If there is a difference the in line analysers are calibrated or adjusted to match the laboratory values. With Maselli systems this is a seamless process as the technologies from the line and laboratory are the same. However Maselli laboratory beverage analysers can also be used to calibrate other manufacturers equipment.
