Definitions

• the invention relates to a drum roaster for roasting beans, such as coffee beans, with a housing arrangement in which a roasting drum for receiving the beans is rotatably mounted, a drive device for rotating the roasting drum and a heating device for heating the beans being provided, the Housing arrangement has as operating elements at least one bean inlet arrangement and a bean outlet arrangement, at least the bean outlet arrangement being provided on a front side of the housing arrangement.
• drum roasters are well known from the prior art and are used in particular as so-called small, shop or shop roasters in smaller roasting plants or shops or cafes. Due to the appealing design and the pleasant roasted aroma, these drum roasters are placed in sales rooms or freely accessible rooms.
• An example of such a drum roaster can be found in the German utility model DE 20 2015 100 90 Ul.
• the drum roaster is operated by operating personnel or an assessment by guests takes place from the front of the drum roaster.
• the roasting drum for receiving the beans which is rotatably mounted inside the housing arrangement, is heated to up to 250 ° during the roasting process by means of a suitable heating device, such as an electric or gas heater.
• the front side in the area of the bean outlet arrangement can heat up to such an extent that it can lead to injuries to the operating staff or guests.
• the front of the housing assembly is made of cast iron. This material is known to have a high heat capacity, which means that the front side can heat up very much and the risk of injury is also increased.
• the object of the invention is therefore to avoid the above-mentioned disadvantage in a simple and inexpensive manner without unnecessarily increasing the installation space.
• the insulation means have a cavity arrangement.
• the front side can consist at least partially of a cover part on which the cavity arrangement is arranged.
• a particularly simple assembly of the drum roaster is ensured in that a bean outlet opening of the bean outlet arrangement with a rotatably mounted closure flap element is provided in the cover part.
• the cavity arrangement is essentially disk-shaped.
• the cavity arrangement can have two partial ring elements on which a plate element is arranged.
• further operating elements such as the bean inlet arrangement, a sampler arrangement and a viewing window arrangement, are at least partially provided in the cavity arrangement. This ensures in a simple manner that operating or simply touching the operating elements cannot lead to burn injuries.
• the bean inlet and bean outlet arrangements are provided in a particularly simple and thus inexpensive manner in that opening areas of the bean inlet and bean outlet arrangements are formed by the partial ring elements.
• the cavity arrangement can be filled with air for thermal insulation.
• a sheet metal part surrounding the roasting drum can advantageously be provided in the housing arrangement at a distance from the front.
• An insulated exhaust air pipe or an insulated exhaust air duct can also be provided in the housing arrangement, as a result of which a particularly compact drum roaster is provided, which also makes it impossible to damage a hot, external exhaust air pipe.
• the housing arrangement has a roasting drum space for the roasting drum and a drive space for at least the drive device, the roasting drum space and the drive space being separated from one another by a wall element with an insulating material.
• FIG. 1 shows a perspective front view of a drum roaster according to the invention
• FIG. 2 shows a perspective sectional view of a housing arrangement for the drum roaster from FIG. 1,
• FIG. 3 shows a perspective front view of a cover part of the housing arrangement from FIG. 2, and
• FIG. 4 shows a sectional view of the drum roaster from FIG. 1 without a base housing part.
• FIG 1 shows a typical drum roaster 2 as a shop roaster.
• the drum roaster 2 has a housing arrangement 4 which essentially has a drum housing part 6 and a base housing part 8.
• the drum housing part 6 is placed on the base housing part 8, the base housing part 8 having a collecting container 10 for roasted beans.
• a roasting drum 12 see Figure 2
• a drive device for rotating the roasting drum 12
• a meat device for heating the beans located in the roasting drum 12
• the view shows a bean inlet arrangement 14 with a bean inlet funnel 16, a sampler arrangement 18, a viewing window arrangement 20 and a bean outlet arrangement 22, which also includes the collecting container 10.
• All of the operating elements 14, 18, 20, 22 are arranged at least partially on a front side 24 of the drum roaster 2 shown here.
• a cavity arrangement 26 is provided on the front side 24 as an insulation means.
• the roasting drum 12 is designed here as a closed roasting drum 12, in which the heat is transferred to the beans located in the roasting drum 12 by means of convection during the roasting process.
• a shovel mechanism 27 is shown that mixes the beans during the roasting process.
• the cavity arrangement 26 essentially has two partial ring elements 28, 30 (see FIG. 3 in this regard) which are arranged on a cover part 32, the cavity arrangement 26 being closed by a plate element 34 placed on the partial ring elements 28, 30.
• the cavity arrangement 26 is essentially designed in the form of a disk.
• the viewing window arrangement 20 and part of a closing flap element 36 of the bean outlet arrangement 22 are shown in FIG. 2 as operating elements, which closes an interior 38 of the drum housing part 6 during the roasting process.
• the closure flap element 36 is rotatably mounted on the cover part 32 and can be operated via a lever arrangement 39.
• the lever arrangement 39 is pivoted and for this purpose releases an opening 40 in the cover part 32.
• the lever arrangement 39 consists essentially of a grip element 41 and a counterweight 43 connected to it via a coupling element 42, which securely closes the closure flap element 36 during the roasting process.
• the beans then reach the bean collecting container 10 via an opening area 44 (see FIG. 3 in this regard).
• FIG. 2 also shows a diaphragm element 45 that covers the opening area 44.
• FIG. 3 now shows the cover part 32 in a perspective view.
• the opening area 46 like the funnel 16 and an inlet element 48 (see FIG. 1 in this regard), is part of the bean inlet arrangement 14 through which the beans are guided via an inlet opening 50 into the roasting drum interior 38.
• the closure flap element 36, a guide member 52 of the sampler arrangement 18 and a conical viewing tunnel 54 of the viewing window arrangement 20 are also shown
• FIG. 4 now shows a sectional view of the drum roaster 2 without the base housing part 8. It can be clearly seen here that a roasting drum space 56 is provided for the roasting drum 12 and a drive space 60 separated therefrom by a wall element 58 for, among other things, a drive device 62.
• the drive device 62 acts in a known manner on a drive shaft 64, which in turn is rigidly connected to the roasting drum 12 via articulation arms 66.
• an insulation material 68 such as for example insulating material, is arranged in the wall element 58, which is essentially composed of two plate-shaped elements.
• a sheet metal part 70 surrounding the roasting drum 12 is provided in the housing arrangement 4 at a distance of approx. 25mm from the front side 24, which acts as an additional Flitzeschild opposite the front side 24.
• an exhaust air pipe 72 is provided, which is insulated in the roasting drum space 56 and in the drive space 60 parallel to the roasting drum 12 with respect to an outside and the drive space 60 of the inlet element 48 of the roasting drum 12 is in fluidic operative connection.
• reference numeral 76 only shows schematically a region of an associated heating device which can be designed in the most varied of forms in a known manner.
