Definitions
- the invention relates to an airtight device close a vessel with a lid and Vessel sealing by creating a vacuum according to Preamble of claim 1.
- the sealing ability of the vessel seal is least in this phase pronounced because of the pressure difference between the Outside air and the inside of the mason jar least is.
- the higher the pressure difference the better the vessel seal seals. It is coming so it depends on the beginning of the cooling phase to ensure an airtight seal which is not the case with this conventional method is always given.
- Another disadvantage is that the food often over that for the actual preparation necessary measure must be heated so by subsequently cooling the for preservation necessary vacuum is reached. Thereby the content of the food is reduced, because important components through the strong heating of the food (e.g. vitamins) destroyed will.
- FR-A-1013066 is the use of a two-part Chamber known that over a membrane are separated, the one chamber for receiving of the vessel to be closed is formed and both chambers independently of one another with an evacuation device or with the atmosphere in Can be connected.
- the dimensioning takes place in such a way that the evacuation of the closing chamber to accommodate the membrane due to the prevailing pressure difference against the lid and this in turn against the vessel seal and squeezes the vessel itself and upon completion the evacuation of the lid from the Membrane is released.
- the membrane from above and across the front and extending the edge area.
- the invention is based on the problem to design a generic device so that at the beginning of the ventilation process, also a vessel of smaller diameter is reliably sealed.
- the object is achieved by that the vascular chamber contains a pressing device, which consists of an essentially cylindrical There is a bolt, part of the cylinder jacket the bolt of one on the wall of the vacuum space fixed guide is enclosed and the Bolt is movable along its axis of rotation, by a spring with one attached to one end Disc is pressed against the membrane and a pressure head at its opposite end having.
- a pressing device which consists of an essentially cylindrical
- the bolt of one on the wall of the vacuum space fixed guide is enclosed and the Bolt is movable along its axis of rotation, by a spring with one attached to one end Disc is pressed against the membrane and a pressure head at its opposite end having.
- the vacuum space consists of two chambers, which are separated by an airtight and stretchable membrane are, the vascular chamber for receiving the Vessel is determined and the pressure chamber for generation of a pressure drop in the vacuum space between Pressure chamber and vascular chamber, which serves is achieved that the pressure in the two chambers can be set independently. So can both the pressure chamber and the vascular chamber either with the outside air or with the vacuum pump get connected. Because of the pressure drop the membrane bulges and presses the lid open the container. Before ventilating the vascular chamber the pressure chamber is brought to external pressure, which ensures because of the pressure on the lid will that even in the initial stages of ventilation the vessel is sealed airtight and the vacuum is maintained.
- valves are expediently as three-way valves executed, each with a valve in the supply to the vascular chamber and the pressure chamber located. They can be switched in each case that either the connection from the chamber to the outside air or opened from the chamber to the vacuum pump is.
- valves happen control of the valves automatically.
- both the vascular chamber and the Pressure chamber is connected to the vacuum pump.
- After reaching a certain negative pressure or after a certain period of time first pressurized the pressure chamber, causing because of the pressure differential between the the diaphragm bulges in both chambers and the lid of the Presses the vessel. Once this is done, too the valve to the vascular chamber is connected to the outside air and thus also ventilated this chamber.
- the stuffed with food Vessel with seal and lid in the vessel chamber is used so that the contact pressure on the Cover can act, so not too far from the pressing device removed and essentially vertical to the direction of action of the contact pressure.
- the Favorable position can optionally be by means of distance inserts can be set. Then the Vacuum space sealed and a vacuum in both Chambers created.
- the pressure chamber becomes a time limit ventilated, which is due to the emerging Pressure difference the membrane bulges and force on the cover of the Exerts vessel. This makes the vessel reliable sealed, even if there is no pressure difference between its interior and the vascular chamber.
- the vascular chamber can finally be ventilated.
- the pressure between the two chambers is the same thereby again, the membrane relaxes and the pressing device is in by the spring brought the starting position and gives the lid free.
- the vessel can now be removed from the vacuum chamber will.
- the drawing shows a schematic Longitudinal section of the device.
- the vessel (1) with lid (2) and vessel seal (3) stands on a distance insert (4) in a vacuum room (5), which appears rectangular in longitudinal section and in reality preferably a circular cylinder is.
- the vacuum chamber (5) has a horizontal one Cutting plane (6), creating the upper part lifted from the bottom and the vessel (1) removed can be.
- the cutting plane (6) is through a Seal (7) sealed.
- the membrane (8) is bulged drawn. It is close to the inner side wall of the vacuum space attached to the upper inner wall.
- the pressure chamber is located above it (9) and below it the vessel chamber containing the vessel (1) (10), which also has a pressing device has, with its disc (12) on the Diaphragm (8) is applied.
- the pressure chamber (9) has a hose connection (17).
- the one for the vascular chamber (10) is the outermost left edge of this top wall attached.
- Both hose connections (17) are via connecting hoses (18) connected to the vacuum pump (19), the connecting hose (18) to the vascular chamber (10) as well as the connecting hose (18) to the pressure chamber (9) contains a valve (20), which makes the two chambers (9, 10) independent from each other either with the vacuum pump (19) or can be connected to the outside air. Between the valves (20) and the vacuum pump (19) are the Connecting hoses (18) brought together into a single.
