Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) Further advantages, features and details of the invention result from the following description of preferred embodiment and from the drawing; these show in

(2) FIG. 1 an overall perspective view of a plant for the production of foodstuffs according to the invention;

(3) FIG. 2 a schematic top view of a processing station of the plant according to FIG. 1;

(4) FIG. 3 a schematic front view of a processing station in the plant as shown in FIG. 1. As shown in FIG. 1, a plant for the production of a foodstuff has various processing stations between which moulds 1 for the production of a foodstuff are transported. The transport takes place on a series of conveyor belts 2.

DETAILED DESCRIPTION

(5) First, the mould 1 is transferred to a preheating cell 3, in which the moulds 1 are preheated. For this purpose, the mould 1 is removed from the conveyor belt 2 by a robot 4 and deposited on trays 5 in the preheating cell 3. For simplicity, the preheating cell 3 has a wall 6 from which the trays 5 protrude. In the exemplary embodiment shown, the trays 5 are designed as U-shaped tubes, as described in more detail below. Above the trays 5 there is an aggregate 7 for supplying heat to the moulds 1 and the trays 5 respectively.

(6) The robot 4 takes the heated mould 1 from the trays 5 again and places it on a subsequent conveyor belt 2.1. This conveyor belt 2.1 transports the moulds to a moulding machine 8. There another robot 4.1 takes the mould from the conveyor belt 2.1 and places it in moulding machine 8. In moulding machine 8, the mould 1 or corresponding recesses/cavities in the mould 1 are filled with liquid food, for example chocolate.

(7) After filling the mould 1, the robot 4.1 takes the filled mould 1 out of the moulding machine 8 and places it on another conveyor belt 2.2. This conveyor belt 2.2 leads to a cooling cell 9 where the filled moulds 1 are cooled. For this purpose another robot 4.2 takes the moulds 1 from the conveyor belt 2.2 and places them on trays 5.1 in the cooling cell 9, as described later.

(8) After the moulds 1 have cooled appropriately, the robot 4.2 takes the moulds from the trays 5.1 and places them back on the conveyor belt 2.2, through which the moulds are transported for further processing.

(9) As shown in FIGS. 2 and 3, the cooling cell 9 is enclosed by a housing 10. The housing 10 is traversed by the conveyor belt 2.2, on which the mould 1 is located.

(10) The robot 4.2 is surrounded by three identically designed walls 6.1, 6.2 and 6.3. From each wall 6.1, 6.2 and 6.3 protrudes a number of trays 5, which are designed as curved tubes. A tempering medium, for example, can be guided in these curved tubes 5. In the case of the tray 5 in the preheating cell 3 it is a heating medium, in the case of the tray 5.1 in the cooling cell 9 it is a cooling medium.

(11) The walls 6.1, 6.2 and 6.3 are each fitted with a cooling unit 11.1, 11.2 and 11.3, from which, for example, cooling air is discharged which falls on the moulds 1 on the trays 5.1.

(12) According to the invention, however, slots 12 are also formed in the walls 6.1, 6.2 and 6.3, in particular between the trays 5.1, through which a cooling medium, especially cooling air, is applied to or under the moulds 1 on the trays 5.1.

(13) The functioning of the present invention is as follows:

(14) Empty moulds 1 are directed on the conveyor belt 2 to the preheating cell 3. The robot 4 takes the empty mould 1 from the conveyor belt 2 and places it on trays 5 in the preheating cell 3, which protrude from the wall 6. The moulds 1 are placed on the trays 5 in such a way that they are only supported at points or in lines, so that as large an area of the mould as possible is exposed to a heating medium without being shielded by a flat tray. In particular, the mould 1 is placed between two tubularly curved trays so that the mould 1 rests on a straight tubular part of each of the two adjacent trays 5. However, the trays 5 themselves can also be designed according to the geometry of the mould 1, so that a mould also rests linearly on a tray.

(15) As soon as the moulds are properly preheated, they are removed again by the robot 4 and placed on the conveyor belt 2.1, which takes the mould 1 to the moulding machine. There the corresponding foodstuff is placed in the recesses in the mould 1, so that the mould is now filled.

(16) This filled mould is removed by the robot 4.1 from the moulding machine 8 and placed on the conveyor belt 2.2. The conveyor belt 2.2 takes the filled mould to the cooling cell 9, where the robot 4.2 takes the mould from the conveyor belt 2.2 and places it on the trays 5.1. In particular FIG. 2 shows that two adjacent trays 5.1 also pick up the mould 1 with a straight piece of pipe, so that in the cold cell 9 almost the entire mould is exposed to the cooling medium without being covered. The slots 12 ensure that the mould 1 is exposed to the cooling medium not only from above but also from below. As a result, a very uniform and rapid cooling of the moulds 1 or the foodstuff in the moulds 1 respectively takes place.

(17) After sufficient cooling, the mould is removed again by the robot 4.2 from the cooling cell 9 and placed on the conveyor belt 2.2 for further processing.
