Definitions
- the invention relates to a method for filling containers with a liquid and a device for performing the method.
- oxygen-free gas spaces head spaces above the foods in the filling containers (e.g. bottles) are desired. So far, this has been achieved either by purging the head space with inert gases (nitrogen or CO 2 ) or by introducing a drop of liquid nitrogen, the nitrogen gas formed displacing the vapor during its evaporation. Both methods have the disadvantage that they are technically complex. Especially when filling the food in bottles, a device must be provided that introduces nitrogen through the bottle neck. Especially at high filling speeds or small neck openings, it becomes more and more difficult to introduce the inert gas through the opening into the headspace of the container.
- inert gases nitrogen or CO 2
- the invention has for its object to eliminate the disadvantages mentioned inerting the head spaces when filling liquid food in bottles or containers.
- the object is achieved in that fine gas bubbles of the inert gas are generated in the liquid food and the container is completely filled with the inert gas-laden liquid food and then sealed. After filling and closing the container, the inert gas separates from the liquid and forms a head space above the liquid that is largely oxygen-free.
- the invention thus relates to a method for filling containers with a liquid, a dispersion being produced from the liquid and an inert gas, the containers being filled with the dispersion and the filled containers then be closed.
- Another object of the invention is a device for filling liquids into containers, which is characterized in that the device contains a gassing device for producing a dispersion of the liquid and an inert gas.
- the device is preferably a filling system for liquids, in particular liquid foods such as cooking oil or syrup, equipped with a gassing device.
- the liquid containing inert gas and containing inert gas bubbles is referred to as dispersion.
- the liquid is usually a liquid food, e.g. B. cooking oil.
- the liquid preferably has a viscosity like edible oil. A high viscosity facilitates the production of the dispersion. A high viscosity leads to a higher stability of the dispersion and slows down the separation of inert gas and liquid.
- the liquid is preferably lipophilic.
- Inert gases are, for example, nitrogen, oxygen-depleted air, noble gases such as helium or argon, carbon dioxide. Mixtures of inert gases are also referred to as inert gases, e.g. B. a nitrogen-carbon dioxide gas mixture.
- Inert gases with a low fat solubility e.g. B. nitrogen.
- the dispersion is preferably produced by introducing the inert gas through fine openings of a gas inlet into the liquid.
- a gas injector is a device with at least one opening for introducing the inert gas, e.g. B. a gas nozzle, a gassing membrane (membrane with openings or pores), a porous body such as ceramic, glass or metal sintered body.
- the inert gas is in usually introduced into the liquid under pressure.
- the pressure is generally in the range from 1.5 to 50 bar absolute, preferably 2 to 20 bar absolute and particularly preferably 2 to 10 bar absolute.
- Containers into which the dispersion is filled are, for example, glass bottles, plastic bottles, cans, canisters, barrels, bags, beverage cartons or cups.
- the containers can be closed.
- a simple device (gassing device) for producing the dispersion is, for example, a chamber into which the liquid is conveyed by means of a pump and the inert gas is supplied via a gas inlet.
- the supply of the inert gas into the chamber is advantageously carried out so that the gas bubbles lead to a good mixing with the liquid.
- the quantitative ratio of inert gas to liquid in the dispersion is determined by the delivery rate of the liquid pump and / or the amount of inert gas supplied, which can be regulated, for example, by means of a manual valve.
- FIG. 1 shows a diagram of a device according to the invention for filling liquids into containers.
- a gassing device 1 is arranged in the feed line to the filling device 8 for filling edible oil.
- the edible oil is transported by pump 12 from a liquid source 13 into the gassing device 1.
- the nitrogen is taken from a gas source 7 (pressurized gas bottle) and passes through a gas line with pressure regulator 6, solenoid valve 5, flow meter 4, adjusting valve 3 and check valve 2 into the gassing device 1, where the nitrogen is finely divided into the cooking oil by means of a porous body is entered.
- the fine bubbles can only rise slowly in the viscous cooking oil.
- a dispersion is formed.
- the introduction of nitrogen increases the specific Volume of liquid.
- the dispersion enters the filling device 8 and is weighed into the containers 10 (bottles) provided, e.g. B.
- the weighing device is set so that the containers 10 are filled to a certain level.
- the filling weight is such that the containers 10 are almost completely filled with the dispersion.
- a gas bubble-free or gas bubble-free liquid zone a, a gas bubble-rich liquid zone b and a gas zone c are formed.
- the liquid level of the cooking oil drops to the desired and previously set level in the container 10.
- the inert gas forms the largely oxygen-free head space c in container 10 (shown as the last container, on the right in the figure).
- Liquid source a liquid b liquid with inert gas bubbles c gas space with inert gas
