    摘要: A sealing device for sealing a cover on a mouth of a container, includes a main machine including a housing, a vacuum pump, an air extraction channel, an air inlet channel and a control valve for controlling open and close of the air inlet channel. The housing includes a sleeve joint part defining a first accommodating space adapted to the mouth. The vacuum pump is arranged in the housing and includes an air extraction port. The air extraction channel communicates the air extraction port with the first accommodating space and the air inlet channel communicates the first accommodating space with ambient air. The sealing device further includes an air duct which may be selectively connected to the housing and is respectively communicated with the air inlet channel and the air extraction channel. The sealing device can not only vacuum and seal jars, but also creates a vacuum in compression bags.

    摘要: A heated portable vacuum slurry box for efficiently storing and transporting material including drill cuttings from gas and oil well sites. The slurry box generally includes a vacuum tank, a structure attached to the tank, a mechanical bay, a vertical tailgate, and a hook for pulling the slurry box onto a vehicle. The features allow for the slurry box to be meet space restriction requirements at a well site while as well as function within the environmental conditions of winter and summer seasons. Jacketed openings, stack mount systems, and a removable power unit allow for efficient use of the slurry box.

    摘要: A system, apparatus, and method of storing food including a storage container having a base; a resilient liner nesting in the base, and a lid that interlockingly engages with the liner and/or base to close off access to foodstuffs retained in a compartment defined by the liner. A valve assembly in the lid is actuated by a pump to evacuate air from the liner's compartment and create a vacuum or near-vacuum condition therein. Apertures defined in the wall of the base allow air to flow into a compartment of the base as the resilient liner shrinks around the food. The closed storage container may be placed in a freezer to freeze the food therein. For defrosting, the base of the closed storage container is placed in a volume of water, some of which flows through the apertures in the base's wall and comes into direct contact with the liner.
