1. Receipt of milk
The effectiveness of subsequent processes can only be evaluated correctly if the initial measurement was correct. Following transport, degassing has the important task of ensuring that subsequent sensors can operate correctly. Optimally operating systems ensure accurate measurement results, quick cooling, and safe further processing of the milk.
Overflow protection against milk and milk foam
CleverLevel®
One of the main tasks inside vacuum-supported degassing containers is protecting the vacuum system from milk or milk foam. To optimally operate the system, the CleverLevel® can be precisely adjusted to the process. This way, it can react to either foam or milk. In the version with sliding connection, the height can additionally be matched to the tank. The extremely robust stainless steel housing features all-round LEDs that indicate the switching state.
Quick level measurement
LSP
In small containers with little content and high throughput, keeping the filling level constant is a challenging task. Thanks to its quick response time, the LSP level sensor is the appropriate solution for such applica- tions. Adhesions such as grease, protein, or lactose on the sensor do not affect the measurement performance.
Treatment of raw milk
CombiPress® PFMH, CleverLevel® PL20H
During its collection and transport, milk can absorb up to 30% air. This prohibits the use of many sensors. Run-time processes hardly have the signal strength to measure the filling level as precisely as the Combi- Press® PFMH hydrostatic level sensor. When it comes to overflow and empty messages in particular, the advantages of the flexible frequency sweep technology of the CleverLevel® PL20H come into play. The level switch reliably detects either the liquid phase or the foam. This also applies if cream, protein, or lactose collects on the sensor.
Temperature measurement in the storage tank
TER8
Temperature measurement in a tank with a stirring unit is difficult because the milk should receive as little resistance as possible. At the same time, it is advantageous if a sensor that is flush in the front can be reliably cleaned with the standard CIP process. The PEEK surface of the TER8 temperature sensor reduces the effect of the ambient temperature and offers mechanical and cleaning advantages compared to protective pipe installations.
Receipt of milk and quantity measurement
CombiFlow® PF75H
Following the degassing, the milk is well prepared for its volume to be measured by a CombiFlow® PF75H magnetic inductive flow sensor. This offers superior accuracy of up to 0.2%, a robust design, and temperature stability. The compact, fully stainless steel sensor provides reliable base data for the subsequent processes. The graphical DFON display with touch function ensures that the information is clearly visible even from a distance.
2. Milk storage tanks
Precision and hygienically clean operations are the key to the successful implementation of the subsequent milk processing steps.
Hydrostatic level measurement
CombiPress® PFMH Long Shell
Planning of the milk quantity to be available for subsequent processes requires precise measurement of the existing quantity. Inside the tank, this is optimally carried out by the CombiPress® PFMH hydrostatic level sensor. The long housing was developed for insulated tanks. The sensor is perfectly suited for the cold environment with condensation precipi- tation. It provides precise measurement values even during hot cleaning processes. In the CombiPress® PBMH variant, the sensor is also available without a DFON display.
Empty tank notification
CleverLevel® PL20H
The application options for a level switch go far beyond the reliable empty notification. The CleverLevel® PL20H protects the tank dome from milk and milk foam, and the pump from dry runs. With its flexible foam detection or blanking, it allows the complete draining of the tank. Thanks to its compact design and small process-contact surface, it can be integrated into the process in a very flexible and hygienic manner. Deposits do not affect its performance. Drops that wash over the sensor during the CIP process, for example, do not result in switching.
3. Thermal treatment
Heat exchange systems combine all requirements for precise measurement. The process should be reliable, ef- fective against microorganisms, yet gentle without affecting product quality and as energy-efficient as possible. Critical control points meet operational excellence.
Monitoring the pasteurization temperature
PT20H
A quick temperature sensor has the greatest effect on the reliability and performance of a heat exchanger. A very quick t90 time as pro- vided by the PT20H allows the safety reserves of the heating to be reduced without risking falling below the PE. This prevents negative effects on the taste and energy consumption due to unnecessarily high temperatures.
Energy monitoring and process safety
FlexFlow® PF20H
Measuring the quantity and temperature of the heating water in the input to the system with the FlexFlow® PF20H makes it possible to determine the use of resources batch by batch. An increased energy requirement is a sign that either the product side must be cleaned or the media side must be descaled in the system.
Pressure gradient
PP20H
After the successful thermal treatment, it must be ensured that the treated milk is not exposed to untreated milk or even the cooling medium. The PP20H pressure sensors measure reliably whether the required pressure gradient is pres- ent. The evaluation of the pressure situation in the system allows optimization of the cleaning cycles. The sensor performance is neither affect- ed by high nor changing temperatures nor by condensation formation in cold areas
4. Filtration
Filtration and membrane filtration systems are used for removing coarse particles or as an alternative to ther- mal treatment. Ensuring the required pressures and flow rates requires the consumption of energy, which can be optimally used with the help of the right sensors.
Filter loading
CombiFlow® PF75H
An accurate measurement of the pump and module performance requires a precise sensor, such as the CombiFlow® PF75H magnetic inductive flow sensor. Monitoring the flow quantity allows conclusions about the load that the modules must bear as well as their current performance capacity. Breakdowns and the need for cleaning can all be detected. The sensor provides an excellent flow signal for both cold production and hot cleaning.
Phase separation
CombiLyz® AFI
The optimum phase separation of water and milk as well as the cleaning media significantly influences the effectiveness of the operation. This applies even more so to filtration systems due to their large surface area. The CombiLyz® AFI conductivity sensor offers the fastest response time even in the case of temperature changes. This reduces losses and increases the system availability.
Monitoring the filter performance
CombiPress® PFMH
Highest precision makes the CombiPress® PFMH pressure sensor predestined to mon- itoring pressure changes in filters. The early response to changes increases the holding time and thus the entire flow quantity. The uniform supply of milk to all membrane sections im- proves the performance of the overall system.
5. Milk standardization
Separators are used for the removal of undesired particles as well as skimming in standardization. Stable input and output processes contribute to optimum operation.
Cream dosage in standardization
CombiFlow® PF75H
The precise dosage of cream is worth every penny. The CombiFlow® PF75H magnetic inductive flow sensor measures with high accuracy in both the cream and the skimmed milk. Its compact, fully stainless steel design facilitates its installation in narrow systems. With the DFON display, the current situation can be monitored any time from a distance as well.
Pressure monitoring of the separator
PP20H
Stable pressure in the input and output to the separator is a basic requirement for the optimum operation of the separator and the return dosage. With its robust stainless steel housing and electronics that are fully secured by socketing, the PP20H pressure sensor provides long- term stable measurement performance. The sensor is not affected by condensation.
6. Homogenization
The high energy consumption of a homogenizer pays off in the form of a more intense milk color and a better feeling in the mouth especially when the process conditions in the surroundings, flow rate, temperature, and pressure conditions are stable.
Energy monitoring
FlexFlow® PF20H
In addition to the electricity needed to operate the huge motor, cooling water can have a significant effect on the operating costs. With the FlexFlow® PF20 calorimetric flow sensor, measurement of the quantity and output tem- perature opens up possibilities for determining consumption and evaluating changes for pre- ventive maintenance. The compact and robust sensor can be easily integrated into the pipe.
Measurement of the input temperature
PT20H
Very precise and very fast temperature mea- surement allows the homogenizer to provide the medium at an optimum temperature. The compact PT20H temperature sensor with its short t90 time allows an early reaction to pre- vent the milk from arriving at the homogenizer too cold.
Homogenization pressure
MEX5
As the pressure on the homogenization valve makes a difference to both quality and energy consumption, the dampened manometer MEX5 shows this pressure reliably at all times. Unaffected by vibrations or high pressure fluctuations, it is a robust everyday tool from Baumer Bourdon.
7. CIP system
Cleaning is one of the most important processes. This is not only due to its effect on product safety and quality but also due to the associated costs that need to be optimized: for water, energy, cleaning agents, and above all the loss of production time. Of course, this starts with hygienically designed systems.
Quality measurement point concentration and phase separation – CombiLyz® AFI
The fast, temperature-compensated conduc- tivity measurement is the prerequisite for the optimal use of cleaning agents and very precise phase changes. In this way, the CombiLyz® AFI conductivity sensor supports the CIP process. The robust sensor body, fully made of PEEK with integrated temperature compensation, provides the measurement values faster than
Quality measurement point flow velocity
CombiFlow® PF75H
With its precision of 0.2%, the CombiFlow® PF75H electromagnetic flow sensor provides precisely the information that is required to ensure cleaning success with the desired flow velocity in the return flow. Temperature changes do not affect the measurement performance. Not only the sensor but also the housing with the DFON touch screen display are fully made of stainless steel and very robust and compact.
Quality measurement point temperature
CombiTemp®
As the temperature plays a key role in reliable cleaning, the CombiTemp® TFRH tempera- ture sensor with its high precision and DFON display ensures compliance with threshold values and their clearly legible display. Similar
to the CombiLyz® and CombiFlow®, the display changes its color if the measured value is outside of the set threshold values.
