Vacuum Packaging The use of vacuum pumps in the packaging process is key to extending the shelf life of products. Vacuum pumps are responsible for evacuating air as well as removing water, vapor, fat, and granular materials before goods go to market. In the chamber packaging process, food is placed inside a vacuum bag and loaded into a packaging chamber where the air can be evacuated, and the bag heat sealed. |

Pneumatic Conveying
The use of positive displacement blowers in pneumatic conveying provides efficient transfer of dry bulk material from point to point at varying pressures and vacuum levels. Pneumatic conveying is achieved by creating a pressure differential along a pipeline and using the air that moves toward the area of lower pressure to move the dry bulk material. This process can be accomplished with a vacuum inducer or by injecting compressed air into one end of the pipeline. Unlike other air moving technologies, M-D Pneumatics’s rotary positive displacement design provides constant flow regardless of pressure. Our positive displacement blowers have been successful in pneumatic conveying applications in a variety of industries for over 60 years. |

Freeze drying The freeze-drying process has seen heightened demand due to an increase in the need for dry foods with extended shelf life, or to make perishable materials more convenient for transport. Freeze-drying is a low temperature dehydration process performed under a vacuum that involves freezing the material, placing under a deep vacuum to reduce the pressure, and adding heat to allow the frozen water to sublimate. To achieve a successful freeze-drying process, it should be repeatable with well-defined temperatures, pressure, and time parameters for each step. |

Sterilization Sterilization is a process designed to remove or destroy all viable forms of microbial life. Ethylene oxide (EtO) treatment methods have been used for decades throughout the low-moisture food industries to safely eliminate pathogens such as salmonella and e-coli. Ethylene oxide is a toxic, flammable gas that breaks down microorganisms on a chemical level. EtO sterilization is often preferred for sterilizing temperature or moisture sensitive products and requires that they be preconditioned in a controlled environment of temperature and humidity. The effectiveness of this process relies four critical factors: gas concentration, humidity, temperature, and time. Kinney’s liquid ring vacuum pump has been a preferred solution in EtO sterilization due to its water sealing and ability to handle flammable gases. |
