  • On-Line Titration

    On-Line Titration

    A fast and accurate analysis of the liming process is an important step in juice purification in a sugar factory. The on-line process analysis enables continuous process monitoring of the beet juice, enabling immediate process regulation. The automated sampling process optimizes reliability.

    The automatic value determination results in a higher analysis frequency and offers current information about the process control. It can rapidly detect variations of the pH-value. The on-line titration system allows the exact dosing of lime to improve clarification and to reduce overdosing. Determination of alkalinity can reduce the consumption of limestone and coke. The aim is to optimize process performance, avoid product losses, and control limit levels. To this end, Schmidt + Haensch instruments are designed to monitor characteristics of process streams.

    • Combination of on-line analysis and automatic control systems
    • Saving raw and auxiliary materials by more effective quality control and better compliance with process and product specifications

  • Ash Color Turbidity Analyzer

    Ash Color Turbidity Analyzer

    Schmidt + Haensch has developed this modular, computer-aided automated laboratory system, based on optoelectronic measuring instruments, which includes not only polarimeters and refractometers but also sugar colorimeters and conductometric ash determination. The system may also be upgraded with pH-determining electrodes, balances, barcode scanners, and all necessary instruments for measuring the most important values in the sugar industry. Schmidt + Haensch is proud to offer systems tailored with different degrees of automation to meet each customer’s needs.

    The Automatic Ash-Color-Turbidity Analyzer of Schmidt + Haensch measures the conductivity in accordance with the official ICUMSA method in a 28 Bx solution (ICUMSA 2002, GS2/3-17). The measuring data can be collected by a data acquisition software package, processed, stored in a data base, and exported to a LIMS system.

    The system is easy to use, delivers reliable results, and saves valuable time that the laboratory personnel can use for other, non-routine work. It is specially designed for sugar laboratories with high sample throughput. An example is the combined automatic determination of conductometric ash and color (ICUMSA) for the sugar industry. The crystalline sugar sample is manually added – no further preparation is necessary – and the sample ID can be detected with a barcode scanner. The system dissolves the sample automatically and dilutes the solution to a defined concentration (50 Brix). It automatically filters the sample and fills the specially designed flow-through tube of the Coloromat. The measurement is carried out at 420 nm according to ICUMSA (2002, GS2/3-17). In a second step, the system further dilutes the solution to 28 Brix to measure the conductometric ash. All measurements are operated continuously. Finally, the whole system is rinsed with water and is ready for the measurement of the next sample; the complete measuring sequence takes ten minutes compared to an hour if handled manually. The measuring values are transmitted to a PC that also controls the whole system, calculates the required results, and transmits all data to a LIMS or MIS system.

    • Automated quality control of crystal sugar color
    • Only one minute lead time
    • Analysis cycle takes ten minutes, including automatic cleaning of the system
    • Easy operation avoids tedious laboratory work
    • In accordance with the official ICUMSA method in a 28 Bx solution (ICUMSA 2002, GS2/3-17)

    Specifications

    Precision colour ± 1 IU ( up to 30 IU)
    Precision colour of turbidity ± 10 %
    Precision ash ± 0.001 %
    Brix liquidity ± 0.1 Brix
  • Ash On-Line Analyzer

    Ash On-Line Analyzer

    Schmidt + Haensch offers an on-line ash analyzer in order to monitor the quality of dried white sugar crystals. The device consists of an automatic sampling system which can also be used in hazardous Atex-zones using conductivity to determine the non-sugar content. The device fulfills the standard lab procedure for ash determination following ICUMSA regulations.

    The system dissolves the sample automatically and dilutes the solution to a defined concentration (28 Brix). Measurement results are immediately transferred to the control room of the sugar factory, enabling personnel to react to changes in sugar production.

    Finally, the whole system is recalibrated with distilled water and ready for the measurement of the next sample. The complete measuring sequence takes 5 minutes compared to a much longer handling time.

    The measurement data are transmitted to a PC that also controls the whole system, calculates the required results, and transmits all data to a PLC or MIS system.

    • Fully automatic ash analyzer for crystal sugars
    • Automatic, repetitive dilution, avoiding handling mistakes
    • Functioning in hazardous Atex-environments using conductivity to determine the non-sugar content
    • Easy operation avoiding tedious laboratory work
    • In accordance with the official ICUMSA method in a 28 Bx solution (ICUMSA 2002, GS2/3-17)

  • On-Line Purity Analyzer

    On-Line Purity Analyzer

    The Schmidt + Haensch automatic Purity  Analyzer is the first system worldwide capable of on-line measurements of factory juices, e.g. sugar juices. Samples are automatically taken from various selection points during processing, e.g. pipes or pans, and prepared for polarimetric and refractometric measurements. The Purity Analyzer combines refractometric concentration measurements (Brix) with near-infrared polarimetry.

    One of the most important advantages of the Schmidt + Haensch Purity Analyzer is its fine-meshed measuring grid. This results in tight process control if the data are also transmitted to the control house. The automatic Purity Analyzer opens up a wide range of innovative possibilities, adaptable to your special needs. Ask us, and together we can work to improve your production process.
