"Arrangement for spraying flowable material" 5

The innovation concerns an arrangement according to the preamble of claim 1.

Arrangements of this type are known, for example, from the applicant's company brochure "Sprühboy 15/16".

Pressure vessels that can be filled with fat by the user serve as material storage containers. The pressure vessels have two connections, one of which is used to introduce a pressurized fluid, such as compressed air, into the vessel and the other serves as the material outlet, so that the flowable fat pressurized inside the vessel is led through the material outlet and a hose to the spray gun where it can be sprayed. In the baking industry, such fat spray arrangements are used to apply a baking release agent to baking trays.

The disadvantage of the known arrangement is that the pressure vessel is opened and refilled by the users themselves. When the pressure vessel is opened, unwanted contamination of the inside of the container can occur, for example

by flour, crumbs or similar. Handling the filling canisters is another disadvantage because a special filling is not always guaranteed. Spilling material is both a hygienic and an economic disadvantage. Disposing of the canisters is an ecological

ical and also economic disadvantage.

The innovation is based on the task of improving a generic arrangement so that it provides an economically, ecologically and hygienically improved operating

wise possible.

This problem underlying the innovation is solved by the design of an arrangement according to the features of claim 1.

In other words, the innovation proposes using the familiar keg barrels, such as those used in the brewery industry, as reusable containers and spraying the fat directly from these barrels.

In comparison to the refill canisters used previously, the container in which the grease is delivered to the user can also be used directly as a pressure vessel! so that additional containers that have to be disposed of are superfluous. In addition, there is no need to transfer the grease, so that contamination

during this transfer. This applies to contamination that can get into the interior of the pressure vessel as well as contamination caused by spilling fat.

The keg closure of the barrel ensures that the barrel is always closed without the coupling attached. Manipulation of the container contents by the user is therefore impossible. This ensures that the hygienic standard that is required in the manufacturing and filling plants of the barrels

water is maintained until the grease is sprayed.

As soon as the storage container is empty, it cannot be used by the user or refilled by the user. To do this, the container is taken as a reusable container to a filling station where the container can first be cleaned and then refilled. This ensures that the container is cleaned thoroughly on a regular basis, thus ensuring a high level of hygiene.

A pressure relief valve can advantageously be provided on the otherwise known coupling piece for keg closures, on the one hand as a safety function, and on the other hand to ensure the most uniform spray operation possible and to avoid inadmissible operating pressures.

Furthermore, the coupling piece can advantageously have a pressure gauge so that the optimal operating pressure can be set and monitored depending on the material to be sprayed.

Compressed air can be used advantageously as a pressure fluid, which can be used as a pressure fluid for many materials and is inexpensive. A diaphragm compressor can advantageously generate the compressed air. The diaphragm compressor is

Its design ensures that no oil or water components can get into the compressed air, so that, particularly when used in the food sector, any hygienic and/or taste impairment of the material to be sprayed can be ruled out.

The entry of water and/or rust particles into the material to be sprayed could also clog the spray head and thereby cause operational disruptions or attack the inside of the barrel and cause material damage there, so that the

The operational reliability of the arrangement is improved by using a diaphragm compressor.

An embodiment of an arrangement according to the innovation is explained in more detail below with reference to the drawing.

In this case, 1 designates a barrel known per se with a so-called keg closure 2, whereby the barrel 1 serves as a storage container e.g. for fat, which is to be sprayed onto baking sheets as a release agent. The liquid applied to the keg closure 2 of the

Barrel 1 attachable coupling piece is shown in the drawing as

Coupling 3 is shown. The coupling 3 can be handled with the help of a handle 4 and has an outlet 5 which leads the material from the barrel 1 through a flexible line 6 to a spray head 7. The spray head 7 is designed as part of a spray gun 8.

The coupling 3 further comprises an inlet 9, whereby compressed air can be fed into the interior of the barrel 1 through the inlet 9 by means of a compressed air line 10. A connecting piece 12, which is provided at the inlet 9 and via which the

Compressed air line 10 connects to the inlet 9, also accommodates a pressure relief valve 11, which is only indicated schematically and opens when a permissible operating pressure of, for example, 7 or 8 bar is exceeded. On the connector 12 or, as indicated schematically, on another

A pressure gauge 14 is provided at the inlet 9, with the aid of which the correct operating pressure can be set and monitored.
