Producing sugar used to be easier. But today, in addition to the fluctuations in the quality of the raw material

which continually have to be compensated for, there are additional challenges: soaring costs for the raw

material, be it cane, beet or cane sugar, high energy costs, along with growing requirements for more

consistent quality of the finished product. In addition, there is increased pressure resulting from the global-

ization of the sector, with demands for levels of efficiency and transparency that were previously unheard

of. But you just have to take some things as they come and try to make the best of them. That is exactly

where we can support you. Regardless of the challenges you have to face in the future.

High product quality throughcontinuous monitoringThe demands for consistent sugar quality, especiallywith regard to crystal size and color, are equally hightoday among both sugar consumers and end users.Meeting this demand is no easy undertaking: youhave to take the raw material as it grows, whether itis cane or beet.

Nevertheless, in order to achieve a perfect result atthe end of the manufacturing process, we offer spe-cific solutions for sugar production from the mo-ment the raw materials are delivered to the factoryto the time the finished goods leave the factory.Whether in the optimum crystallization process orthe regulation of the juice preparation based on theraw materials, our integrated solutions provide con-tinuous control and precise handling of all stages ofthe process and ensure constant quality all the wayto the finished product.

Maximum profit with integrated automationGiven the different process steps in sugar refineries,it is absolutely essential to keep an eye on the entireworkflow, at both process and plant management

level, if production is to be optimized. Our automa-tion systems based on Totally Integrated Automationsupport this integrated approach, as they allow end-to-end automation of all the process stages fromgoods-in to goods-out. With its end-to-end integra-tion, Totally Integrated Automation plays a big partin keeping production costs down, while at the sametime improving transparency, quality and the avail-ability of your production in the long term.

Reduced costs due to lower use of energyOne of the major cost factors in sugar production isthe energy required. The best example is starting upand stopping the centrifuges.

Controlled crystallization for crystal-clearadvantages all the wayNAHMAT Pan Control automates the entire crystal-lization process from drawing in the viscous juiceto discharging the massecuite. The system recordsall the required readings such as juice level, viscosity,steam pressure, vacuum in the juice chamber, tem-perature or status of the drive and control units andconverts them into control pulses according to theprogress of crystallization.

At the same time, NAHMAT Pan Control monitors thenonlinear characteristic of the viscosity measure-ment. The required value for the juice control outputis taken from the boiling graph, which is assigned tothe corresponding product and pan. Since the auto-matic pan boiling system of a crystallization pan can

The ingredients for maximum productivity:automation and control technology

If you want to produce sugar with maximum efficiency,

you must look at the overall picture: the entire process

chain from the incoming raw materials to the outgo-

ing goods. Because the more integrated the workflow

is, the greater your competitive edge. We can offer

you the appropriate ingredients in the form of Totally

Integrated Automation and the NAHMAT PCS 7 process

control system that perfectly combines all stages of

the process, thereby ensuring productivity along the

entire line.

store several boiling curves, one pan can seamlesslycrystallize different products in succession. WithNAHMAT Pan Control you can either implement asingle automation process or integrate the entirecrystallization process into a higher-level processcontrol system such as NAHMAT PCS 7.

Perfect process control all through the factoryNAHMAT PCS 7 is suitable for the automation of com-plex plants and process cells. Even in its minimumconfiguration, the process control system can auto-mate a variety of operations, including, for example,10 to 12 crystallization units, an evaporation stationor a juice purification system. Complete automation ofan entire sugar product plant requires that a wide ar-ray of automation and HMI systems all work togethersmoothly. The networking of these systems ensures

that the data from all readings is available to all busstations. Smaller distributed systems such as NAHMATPan Control or control units for centrifuges, scales,filters and other machines, for example, are connectedto the entire system.

Our process control system has the option of beingintegrated via an innovative PROFIBUS network orconventionally wired for example in the course of aplant modernization project.

Power and efficiency at once:drive technology

Drives keep production running in all sectors of industry. As a leading vendor, we offer a vast range of

different drive systems. From motors and converters to gearboxes, supplemented by our special range of

solutions for the sugar industry, ranging from small drives for servomotors and standard drives for pumps

to special drives for centrifuges.

Energy-efficient drivesFor maximum energy efficiency, we can help youto select the appropriate drive. Within our completerange of standard drives we offer you a whole va-riety of highly ef ficient motors and frequency con-verters. Especially in the field of flow control, thesedemonstrate their value as an economical alterna-tive to mechanical controllers, thanks to their throt-tle flaps, as they consume up to 50% less energy.

Ultrafast and powerful centrifugal drivesSiemens has already installed over 1,000 converter-powered AC drives for centrifuges worldwide, in newfacilities as well as for upgrades. The unique sellingpoint: high hourly cycle counts and fill masses thatcan exceed 2,000 kg per batch.

Whether based on SIMOVERT MASTERDRIVES or theSINAMICS series of drives, we offer you a reliablesolution for batch centrifugal drives from a singlesource: from motor and converter, through control-ler and command unit to the software itself.

All our AC drives are designed and manufactured tothe highest technical standards. The use of activefront end (AFE) minimizes line reactions and opti-mizes plant reliability, especially when it comes tofluctuations in voltage and power outages. To imple-ment the technological parameters, our drives canbe integrated into the higher-level control system

without difficulty. In addition, a command unit withan operator panel or multipanel facilitates extensiveon-site operation, diagnostics and troubleshootingdirectly at the centrifuge.

Towering performance from tower drivesThe integration of the extraction tower into theprocess control system with all key values and pa-rameters is now standard procedure in many sugarplants. The tower drive consists of several motors,as many as ten. Steps must be taken to ensure thatthe total torque is evenly distributed among the indi-vidual motors. Siemens offers two different drivesolutions: either with a group converter for all mo-tors or with individual converters for each motor.

Electrically driven sugar cane millsInstead of steam turbines, electrical drives are beingused in a growing number of sugar cane mills thesedays. They operate at a significantly higher level ofefficiency, can be integrated perfectly into the con-trol concept and, of course, do not require any steamnetwork.

As a response to the demand for maximum avail-ability with minimum maintenance expenditure,sugar factories are now generally opting for modernconverter drives for their mills. The same applies tothe drives of cutters and shredders in the sugar caneindustry.

Refined control:instrumentation and MIS

What is the point of the best automation system if you do not have the necessary

instrumentation? Sensors and actuators are the senses of the system. Our exten-

sive range of measurement and analysis equipment offers you the right solutions

for every requirement.

Precise recording of measured values for acomplete overviewThe quantity of data that are exchanged and pro-cessed on a daily basis in modern factories neverstops growing. Not only do many of the analogvalues have to be recorded quickly and comprehen-sively, but the operator should also be able to checkthe process reliably at all times. To ensure that theright action can be taken if need be, our advancedmeasurement and analysis units provide all availabledata with a hierarchical structure where necessary,with relevant details as well.

In combination with NAHMAT MIS, our managementinformation system for the sugar industry, all ourautomation packages offer perfectly graded func-tionalities that keep the essential factors in focus:the process and the operator who has to control it.

Integrated networking via PROFIBUSExchanging information is a decisive success factor,even in process automation. One crucial aspect isthe optimum interaction of all automation com-ponents: from measurement transducers or limitswitches via the analysis system or the converter tothe engineering system on the upper level of theprocess pyramid.

These days instrumentation engineers in a sugar fac-tory must act faster than ever before: fault analyseshave to be performed within the shortest possibletime, new transducers must be capable of imme-diate calibration in the field. And the maintenancedepartment must be informed of which maintenanceprocedures are to be carried out and when. None ofthis could be done without the universal networkingof all components via PROFIBUS.

The management information system for thesugar industryWhat the operator panel is for the plant operator,the management information system (MIS) is forthe management of a sugar factory the window tothe process. Laborious manual calculations are nowa thing of the past, because electronic informationsystems such as our tried-and-tested NAHMAT MISprovide information at all times about the overallperformance of your factory. With specific tailoredcalculations and presentations or balance sheetsthat show how much sugar is present in your plantin soluble form, or how much auxiliary material iscurrently being used.

As an integrated system partner, we offer everythingrequired for a modern management informationsystem: from assembly and service, to spare partsand maintenance, to teleservice and training.
