Tailor made gas mixers for protective gas atmospheres in the food and beverages industry

To prevent loss of natural freshness and quality, food are often packaged in a protective atmosphere (Modified Atmosphere Packaging – MAP). Using natural gas the quality is maintained and the durability is improved. For this different gas mixtures are needed which can be produced in LT’s gas mixers. I.e..:

  • Raw red meat or raw dark poultry:
    O2 and CO2 (Oxygen and Carbon Dioxide)
  • Raw white meat, cooked meat or sausages:
    COand N2 (Carbon Dioxide and Nitrogen)
  • Raw Fisch:
    CO2, Oand N(Carbon Dioxide , Oxygen and Nitrogen)
  • Smoked fish, boiled fish, crab/shrimp
    COand N(Carbon Dioxide and Nitrogen)
  • Hard cheese, soft cheese, yoghurt
    CO2 and N(Carbon Dioxide and Nitrogen)
  • Vegetables, salads
    O2, CO2 and N2 (Oxygen, Carbon Dioxide and Nitrogen)
  • Beer, Champagne, Sparkling Wines
    CO2 and N(Carbon Dioxide and Nitrogen)

LT GASETECHNIK’s serial gas mixers for two or three gases for the food industry have a capacity of a few liter per minute (l/min, slm or slpm) to 500 cubic meters per hour (Nm³/h or scm/h). They are optionally available

  • with or without a buffer vessel
  • with or without gas analyzer
  • as static gas mixer with manual control or
  • as dynamic gas mixer with fully automatic control with MFC (Mass-Flow-Controller)

Dynamic gas mixers typically display process data, alarms and error messages on a local operator panel and, if desired, are passed to the process control system of the customer.

Project examples

  • MFC-based gas mixer for carbon dioxide and nitrogen (beer gas); capacity: max. 150 m³/h
  • Gas mixers for three gases (N2, CO2, H2)
    for fully automatic test of the tightness of food packaging
  • Gas mixers for N2, CO2, mixing ratio 60% / 40%; Capacity about 125 m³/h
Static gas mixer for three gases with gas analyzer
Static gas mixer for three gases with gas analyzer
Static gas mixer for two gases
Static gas mixer for two gases
Static gas mixer for three gases
Static gas mixer for three gases

 

Advantages

  • Particularly high accuracy and reproducibility
  • Static or dynamic, fully automated systems with cascade ratio control
  • Control, analysis and documentation of results with tailor-made solutions
  • Connection of the equipment to existing plant PLC and / or telemetry
  • High availability incl. remote maintenance
  • Redundant versions: Switching over without pressure peaks
  • Unmatched security: Redundant measurements

….just beyond standards
