The device according to the invention consists of a tunnel 1, in which different products, in particular food, by means of heat, cold, smoke or any other, are treatable in the following agent generally referred to as treatment agent. The tunnel 1 is against Insulated and designed so that there is no loss of heat of treatment agent occurs. The tunnel 1 has a treatment agent supply channel 3 by hand or automatically adjustable throughput and dosing devices. In the upper part of the tunnel there is an air heater H with two fans 5, by means of which the treatment agent such as smoke is circulated inside the tunnel. the The circulation of the treatment agent is carried out by means of arranged at appropriate points and designed in a precisely coordinated manner Guide surfaces 6 favored, so that the capacity of the Treatment agent is optimally used. Only that much treatment agent is fed through the feed channel as in the treatment it is lost, whereby it is

409810/106 4

are extremely small amounts, or as is necessary due to the exhaustion of the treatment agent. Within of the air heater U are tube bundles 7, through which a heat exchanger can be circulated, which the Treatment agent supplies or withdraws heat. There are also additional ones for feeding in treatment agents Auxiliary supply channels 8 are provided, by means of which the efficiency the facility can be increased.

Inside the tunnel 1, the through a loading opening 9 treated products. For this purpose, the products within the tunnel 1 are on moved in a circular path, and leave this in turn through a discharge opening 32. The products are treated on grids 10, which move on several floors will. The number of floors is not subject to any restriction. In the drawing are for example nine floors 11-19 are shown. The products pass through the various floors of tunnel 1 from below upwards in alternately opposite directions on the different floors. The reversal of direction takes place at the end of each floor simultaneously with the transfer of the grate 10 to the next higher floor. To that end is a floor switch 21 on the side of each floor facing the discharge opening 32 and on that of the loading opening 9 of the tunnel 1 facing the side of each floor a differently designed floor switch 2 2 is provided.

to

It is obvious that the products with the / treated occupied grids 10 must be moved in a perfectly horizontal position so that the products do not falling off. This applies to all points of the circular route, on which the grids 10 are covered with a product to be treated. Therefore, the grids 10 become parallel moved to itself. It is especially important here

409 810/1064

pointed out that the grids 10 in the drawing only for the sake of clarity, each under a small Angle inclined to the direction of movement are shown. In practice, the grids are perfectly horizontal Position moved as long as they are covered with a product whose treatment has not yet been completed.

As soon as the product located on the grids 10 has reached the end point 20 on the top floor 19, the Treatment fully completed. . Behind this end point 20, the grids 10 are arranged at this point by means of a Turning switch 60 is brought into continuously more inclined positions and finally into vertical alignment. By means of brushes 30 indicated schematically in FIG. 1, the products that may have adhered to the grates are thrown off and then fall onto a conveyor belt 31, which these the discharge opening 32 on the tunnel 1.

The grids 10 freed from the finished products are further closed in a vertical direction down to the bottom a downward endpoint 34, at which they turn in the horizontal orientation to receive a new load of products to be treated for the treatment circulation path to be brought. For this purpose there is an erecting device between the lowering point 33 and the lowering end point 3U 35, by means of which the grids 10 are brought into the position required for covering with products.

Subsequent to the downward end point 34, the are used for recording new products in the aligned on their circulation path through the tunnel 1 grids 10 on a horizontal Return path fed to the end point 53. A cleaning device is located on this horizontal return path with brushes 58, by means of which the grids are subjected to a thorough and effective cleaning. At the end

409810/1064

- ft -

point of the horizontal return path 53 is a Lifting device 59, by means of which the grids 10 are fed to a front end point 61, which is in a certain horizontal distance in front of the loading opening

9 of tunnel 1 is located. One at that front end point 61 arranged and used for aligning the grids 10 in the horizontal position deflection device 54 guides the grids

10 along a horizontal loading path 62, on which they are again covered with products to be treated, the loading opening 9 to.

Also behind the loading opening 9 of the tunnel 1 will be the grids 10 moved in an exactly horizontal orientation. The grates are therefore in continuous use in one self-contained circulation path.

As can be seen from FIG. 2, one according to the invention laid grate 10 has a shaft arranged at the front end and a shaft arranged at its rear end on. The shaft M-I is solid with two parallel to each other Chains 42 connected, which by means of chain rollers along rails 146 over the grids 10 in all Move around the floors covered. the Chains 42 are guided in a manner known per se over chain wheels 43, for example at the two ends of each horizontal path of movement at the floor switches and 2 2 can be arranged. The chain wheels 43 are driven by a transmission, not shown here, see above that the grids 10 are moved by means of the chains 42 along the closed circuit path. The sprockets 43 are mounted on shafts 43a that are fixedly connected to the machine frame.

The grate 10 carries at the end facing away from the shaft 41 a further shaft 44, which carries two rollers 4 5 at its ends, which over the entire circulation path on a parallel and

409810/1064

Roll the pair of rails 46 running within the rails 146. The grids 10 are therefore perfectly horizontal Alignment held and can also be pivoted about the shaft 41, since üie rollers 45 only unroll the rails 46. This training allows the grids to be transferred from one floor to the next with unchanged horizontal alignment of the grids.

The chains 42, which are connected to the shafts 41 of the grids 10, are used to move the grates and transfer the same from one to the next higher floor by means of the chain wheels 43 arranged in pairs, from ■ each of which is assigned to a chain 42 and guided on the shaft 43a (FIG. 2). The sprockets 43 the chains 42 lead on an arc of a circle as indicated schematically in FIG. 3 by the arrow 23.

The rollers 45 rolling on the rails 46 of the lowest floor 11 are also moved to the next higher Floor transferred without the grate 10, which must be held horizontally and parallel to itself, is tilted. For this purpose, the rails 46 (Fig. 3) are guided in the horizontal direction up to a point, at which the rollers 45 are when the lifting of the shaft 41 begins. Since from this point on the The grate 10 would be tilted if the shaft 44 were not raised in the same way, the rails 46 are extended at this point by circular arc-shaped rail sections 49. The rollers rolling on the rails 46 4 5 are arranged in extension of the rails 46 at the ends of each horizontal path of travel Gears 47 raised to the next higher floor. The gears 47 have a kinematic such as median a chain not shown here with the shaft 43a connected to the shaft 47a, the connection of the two shafts is such that sprocket 43 and gear 47 are with

409810/1064

rotate at the same speed. On the circumference of the gears 47 is a series of incisions 48 in which the rollers 45 engage when the shaft 41 from one to the next higher floor is raised. Between the lower rail 46 and the upper rail 46b is the circular arc-shaped one Rail section 49 is interrupted and allows the rollers 45 to pass through.

The fixed rail 46b prevents the transfer of the shaft 41 to the next higher floor and is therefore with a Provided about a pivot 52 pivotably mounted, adjustable element 51, which for the passage of the shaft 41 accordingly the arrow 24 can be pivoted to the side, after the shaft 41 has passed through it again into its closed position falls back and allows the subsequent rolling of the roller 45 over the element 51.

On the side of the loading opening 9 at each floor end arranged floor switch 22, the grids 10 are fed in such a way that the shaft 41 is at the front end, and the shaft 44 with the rollers 45 at the rear end of the Grate, seen in the direction of movement, is located. The floor switch 22 has a pair of sprockets 43 that a driven or only serving for guidance shaft 43a is mounted. Here, too, the chains 42 and the shafts 41 are raised from one floor to the next. A gear 47 guided on a shaft 47a has on its periphery a series of incisions 48 in which the roller 45 engages at the moment the shaft 41 begins to move upward. The gear 47 lifts the rollers 45 at this moment. the the two shafts 47a and 43a are also kinematically coupled to one another, so that the shafts 44 and 41 of the grate 10 can be raised simultaneously and evenly. The rails 46 are curved around the gears 47 Rail sections 46a extended, but not fixed

409810/1064

can be arranged upright, since they otherwise hinder the passage of the shaft U1 connected to the chain U2 would. The rails therefore have an interruption 2 5 through which the shaft U1 is passed. the Interruption 2 5 is with a normally folded back and allowing the free passage of the shaft Ul Flap 2 6 provided. As soon as the shaft Ul the sprocket U3 reached, a pedal 27 is actuated, which is connected to the flap 26 via a rod 28 and a joint 29. the As it passes, the shaft depresses the pedal 27, causing the flap 26 to move into the dashed lines in FIG. 5 position shown is raised. The curved section 46a of the rail U6 is thus closed, and the roller U5 is picked up by gear U7. The two waves Ul and UU will therefore be exactly like the one on the side of the Discharge opening 32 arranged floor switch 21 at the same time and evenly from one to the next higher floor raised.

The turning point 60 for grids 10, which have passed the end point of the top floor 19, is designed as follows: The chains 42 running horizontally up to the end point 20 run at this point over two sprockets 43 and are deflected downwards by them. The chains then run along a path inclined towards the interior of the tunnel 1 as far as a downward end point 34 and thus provide the path of movement for the waves U1 of the grates 10. The grids are thus turned behind the end point 20 for the delivery of the finished product. Upon arrival at this end point 20, the shaft 44 with the rollers 45 is in the direction of advance in relation to the shaft 41 held by chains 42 (FIG. 6). The rail 46 is provided with a curved rail portion 46c on which the lowering of the rollers U5 is initiated. The rollers U5 then come into engagement with the outsides U6d of rail elements

409810/1064

which the roles are deflected downwards. An interruption 5 5a in the rails 46 allows passage of the rollers 45 to the inside of the rails. The shaft Ul of the grate 10 firmly connected to the chains 4 2, which reaches the turning point after the shaft UU, is guided by the chain rollers 1U2 rolling on the rails 146.

The grids 10 are in this way in a vertical orientation transferred, with the loading side of the grids facing the side of the conveyor belt 31 (Fig. 1), and the Grates both under the influence of gravity acting on the products and by the brushes 30 of the product are exempt. The brushes 30 are supported against the grids 10 and cause the detachment, for example products still adhering to them. At a lowering point 33, the grids are deflected so that they are at the downward end point 3 4 are again aligned horizontally and are on a horizontal path of travel to the end of the loading process, of the tunnel 1 move (Fig. 7). For this purpose, an erecting device 35 is provided which has two chain wheels U3 guided by a driven shaft or only used for guiding shaft U3a, which Divert the chains U2 in the horizontal direction. the Rails U6 are provided at this point with an interruption 56 through which the shaft UU of the rollers U5 is carried out will. The rollers U5 are then taken up by a rail element U6c, with them on the outside thereof unroll and remove from the outside of the U2 rail. There is one on the rails 46 further interruption 57 through which the shaft 44 of the rollers 45 is carried out. The rollers 45 are then taken up by a rail element U6f of the rails U6, brought into horizontal alignment and roll then on the rails U6 to an end point 53 of the horizontal Return path. The rollers U5 move with it along the U6 rail, then along the outside of the

409810/1064

Channel elements 46e and finally along the rail reduction 4Cf. The chain rollers 142 roll on the rail 146 (FIG. 7). This device thus allows the grids 10 to be returned to the orientation required at the loading opening 0. The grate surface held by the frame of the grate protrudes from the frame to improve the treatment and faces upwards. At the loading opening 9, the shaft 41 is located at the front in the direction of movement. A cleaning device with brushes 58 (FIG. 1) is located on the return path.

Arrived at the end point 53 of the horizontal return path, put the grids 10 back an upward path of travel, through which they to the front end point 61 of the circulation path with respect to the path of movement within the tunnel 1.

At the end point 53 of the horizontal return path is a lifting device 59 arranged (Fig. 8). This device has two pairs of sprockets 43b and 43c, on which the chains 42 and thus the shafts 41 initially slightly downwards and then obliquely upwards in the direction of the front end point to get distracted. The rails 46 are at the location of the sprocket 43b with one for passing the shaft 41 through Serving interruption 63 is provided and behind this with respect to those moving along the rail 146 Chains 4 2 continued at a greater height. The interruption 63 is periodic and exactly at the time of The passage of the rollers 45 is filled by a cam 64 which rotates at a corresponding angular velocity and is connected to the shaft 43a carrying the sprockets 43. The sprockets 43 move the chains 42, with at the same time the shafts 44 with the rollers 45 from the lower section of the rails 46 to an upper section 4 6ß, which the grids 10 are raised from the end point

409810/1064

53 the horizontal path of circulation to the front end point 61 feeds.

A grate 10 that has arrived at the front end point 61 (Fig. 9) will convey a deflection device 54 serving to align the grids in a horizontal position to one horizontal loading path 62 brought. The deflection device has a pair of sprockets 43, through which the chains 42 and thus the shafts 41 on the horizontal path of travel be redirected. The rails 46 are extended by circular arc-shaped rail sections 46h. in the The center of curvature of these circular arc-shaped rail sections 46h is a shaft 47a with a pair of gearwheels 47, the gears 47 likewise having incisions on v / iron in which the rollers 45 engage. The rail element 46a has an interruption 64a for the passage of the rollers 45, which are on a horizontal rail 46b are deposited. The shafts 47a and 43a are coupled together so that the sprockets 43 and the gears 47 are driven at the same rotational speed and thus a grate 10 is raised parallel to itself and is diverted.

The grids 10 move along the horizontal loading path 62 (Fig. 1) to the loading opening 9 of the tunnel 1 and enter this with a new one The load is occupied again in the treatment cycle, i.e. it covers a closed circuit.

The device proposed according to the invention can be largely modified; for example, instead of the grates moving within the tunnel also in other ways trained receiving or holding devices be provided for products to be treated. The products can be attached to hanging brackets or hooks, for example be hung up or carried on skewers.
