PATENT OFFICE.

In roasters for coffee and the like, it was difficult to produce powdery or granular additives, such as sugar, shellac and the like, to the roasted food for the purpose of glazing, candying etc., to be added during or immediately after roasting in an appropriate manner.

You had to rely on the additives simply through the opening of the roasting container

ίο to throw in. For this it was necessary to use the roasting drum take off the fire, remove the lid, add the additives, close the opening again and the roasting container to bring it back on the fire. The additive that is thrown in at once is of course only slowly distributed over the roasted food, often it clumps together with part of the roasted food, so that lumps are formed when it is emptied come out.

Just by adding the glazing agent in small portions and turning the roasting container better mixing can be achieved after each addition. But this requires an even more laborious, because often too Repeated removal and insertion of the roasting container, opening and closing same.

In the case of roasting containers with a fixed top wall, it is not necessary to remove them,

if you provide the head wall with an opening for pouring in and the additives pouring through this. However, this method also has considerable disadvantages. That Poured glazing agent does not get into immediate mixing with the roasted food, it does melts, runs down the head wall, smears it, as well as that of the head wall first lying part of the drum and lingers too long on the side. It depends on the smeared areas Roasted food, and there is again a cause for inconveniences, consisting in the formation of lumps and delayed mixing of the additive with the roast, hanging beans, smearing the top wall as well of the roasting container.

The present invention makes it possible to supply the additive to the roasted material in such a way that it ^{comes into immediate direct contact with it without opening 4 of} the roasting container, and secondly, while the roasting container is rotating, it is, as it were, scattered over the roasted material.

The method consists in that the additive is carried out by a screw conveyor if possible conveyed far into the roasting container and spread over the roasted material in a fine distribution becomes, while the roasting container is rotating and the roasted food is lively Movement is located.

The apparatus used for this consists of a funnel A, which receives the glazing agent, and in an adjoining tube B in which a screw conveyor C is mounted (FIG. 1).

The tube is inserted into the hollow axis of the roasting container D (Fig. 2) or, in the case of roasting containers with a fixed head wall, into the opening of this wall and leads to approximately the middle of the roasting container.

If you now turn the screw with the crank, it will convey the glazing

medium into the roasting container and gradually sprinkles it in as quickly or slowly as you like fine distribution directly onto the by turning the roasting container in lively motion roasted food. It is evident that this results in all of the abovementioned evils be eliminated.

There are roasters known, which with screw conveyors for

ίο inserting the roasted food are firmly connected; The latter, however, cannot be used to introduce the glazing agent because they are natural must be chosen so large that the roasted material is transported quickly into the roasting drum will. Their size therefore makes them suitable for introducing glazing agents that only come in small portions (around 1 kilo on 100 kilos of roasted food) are unsuitable because this small amount of one large snail can not be sprinkled in fine distribution, but all at once is thrown in, which brings back the abovementioned evils, which just now are to be avoided, so that such roasters are still after all would have to receive a special glazing apparatus. But it would also be permanent Connection of the screw conveyor with the roasting apparatus is very cumbersome because it is connected to their body protruding into the interior of the roasting drum and then attach the roasted food to them and then spoil would. It follows that the apparatus described, in that it can be pulled out is, has a particularly important property for glazing. The facility that the apparatus is not firmly connected to the roaster, but is constructed as a whole for itself and with each one Roasting apparatus can be used by putting it in the otherwise for the pattern maker Inserting a serving or another opening and putting it away after use gives him another new technical one Characteristic.

The device described can also be set up so that the screw, instead of using a crank by hand, rotated automatically by the rotating roasting container in which you connect the screw with the rotating axis of the roasting container or with the rotating roasting container itself couples in an appropriate manner.
