  2. Portable oxygen concentrator - Wikipedia

    en.wikipedia.org/wiki/Portable_oxygen_concentrator

    Portable oxygen concentrator used with bottle humidifier. POCs operate on the same principle as a home concentrator, pressure swing adsorption. [6] The basic set up of a POC is a miniaturized air compressor, a cylinder filled containing the sieve, a pressure equalizing reservoir and valves and tubes.

  3. Oxygen scavenger - Wikipedia

    en.wikipedia.org/wiki/Oxygen_scavenger

    An oxygen absorber The contents of an oxygen absorber from a packet of beef jerky. Oxygen scavengers or oxygen absorbers are added to enclosed packaging to help remove or decrease the level of oxygen in the package. They are used to help maintain product safety and extend shelf life. [1] There are many types of oxygen absorbers available to ...

  4. Silica gel - Wikipedia

    en.wikipedia.org/wiki/Silica_gel

    Colloidal silica gel with light opalescence. Silica gel is an amorphous and porous form of silicon dioxide (silica), consisting of an irregular tridimensional framework of alternating silicon and oxygen atoms with nanometer-scale voids and pores. The voids may contain water or some other liquids, or may be filled by gas or vacuum.

  5. Oxygen concentrator - Wikipedia

    en.wikipedia.org/wiki/Oxygen_concentrator

    An oxygen concentrator takes in air and removes nitrogen from it, leaving an oxygen-enriched gas for use by people requiring medical oxygen due to low oxygen levels in their blood. [4] Oxygen concentrators provide an economical source of oxygen in industrial processes, where they are also known as oxygen gas generators or oxygen generation plants.

    Packaging machines may be of the following general types: Accumulating and collating machines; Blister packs, skin packs and vacuum packaging machines; Bottle caps equipment, over-capping, lidding, closing, seaming and sealing machines; Box, case, tray, and carrier forming, packing, unpacking, closing, and sealing machines; Cartoning machines

  7. Chemical oxygen generator - Wikipedia

    en.wikipedia.org/wiki/Chemical_oxygen_generator

    A chlorate candle, or an oxygen candle, is a cylindrical chemical oxygen generator that contains a mix of sodium chlorate and iron powder, which when ignited smolders at about 600 °C (1,100 °F), producing sodium chloride, iron oxide, and oxygen at a fixed rate of about 6.5 man-hours per kilogram of the mixture. The mixture has an indefinite ...

    5A small oxygen-enriched: 5: 0.4–0.8: ≥23: Specially designed for medical or healthy oxygen generator [citation needed] 5A: A-5, Ca-A: 5: 0.60–0.65: 20–21: 0.3–0.5: Desiccation and purification of air; dehydration and desulfurization of natural gas and liquid petroleum gas; oxygen and hydrogen production by pressure swing adsorption ...

  9. Modified atmosphere - Wikipedia

    en.wikipedia.org/wiki/Modified_atmosphere

    These types of machines are typically called pillow-wrap, which horizontally or vertically form, fill and seal the product. [5] Form-fill-seal packaging machines are usually used for large scale operations. In contrast, chamber machines are used for batch processes. A filled pre-formed wrap is filled with the product and introduced into a cavity.
