Customized gas mixers for protective gases in the food and beverage industry

In order to prevent the loss of natural freshness and quality, modified atmospheres are often used in the food and beverage industry (modified atmosphere packagingMAP). With the help of natural gases, the quality of the food is preserved and its shelf life improved. A wide variety of gas mixtures are used for this purpose, which can be produced in LT gas mixers. Z. B.:

  • Raw red meat or raw dark poultry: O2 andCO2 (oxygen and carbon dioxide)
  • Raw white meat, cooked meat or sausages:CO2andN2 (carbon dioxide and nitrogen)
  • Raw fish:CO2, O2andN2( carbon dioxide, oxygen and nitrogen)
  • Smoked fish, cooked fish, crabs/shrimps:CO2andN2( carbon dioxide and nitrogen)
  • Hard cheese, soft cheese, yoghurt:CO2andN2( carbon dioxide and nitrogen)
  • Vegetables, salads: O2,CO2 and N2 (oxygen, carbon dioxide and nitrogen)
  • Beer, sparkling wine, sparkling wines:CO2andN2( carbon dioxide and nitrogen)

LT GASETECHNIK’s standard gas mixers for two or three gases for the food and beverage industry have a capacity of a few liters per minute (Nl/min) up to 500 cubic meters per hour (Nm³/h) and are optionally available as

  • with or without buffer tank
  • with or without gas analysis system
  • as static gas mixers with manual control or
  • as dynamic gas mixers with fully automatic control with MFC (mass flow controller)

executed. For dynamic gas mixers with an analysis system, the process data, alarm signals and fault messages are usually displayed on an operator panel and, if required, transferred to the customer’s process control system.

Project examples

  • MFC-based gas mixer forCO2 and N2 (carbon dioxide and nitrogen = beer gas);
    Power: Max. 150 Nm³/h
  • Gas mixer for three gases (N2,CO2, H2)
    for fully automatic leak testing of food packaging
  • Gas mixer for N2,CO2, mixing ratio approx. 60%/40%; capacity approx. 125 Nm³/h

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 systems to existing control systems and/or telemetry
  • High availability incl. remote maintenance
  • Redundant versions: Switching over without pressure peaks
  • Unmatched security: Redundant measurements
