Abstract

Device for continuously and quickly cooking foodstuffs with horizontal and vertical transfer, and automatic loading and unloading. It consists of the combination firstly of a perforated volume-loading upper area 1 with carrying edges by endlessly translating cables or belts 5, then of an intermediate vertical- transfer chamber 2, 3 arranged at each end and finally of a lower heating cooking area 29 with horizontal transfer via endless carrying cables or belt 8. It is intended to allow the continuous and rapid cooking of any foodstuffs in large quantity, either by frying, steaming or boiling with vertical and horizontal loading translations and automatic unloading.

Description

 Device for continuous and rapid cooking of foodstuffs with horizontal and vertical transfer, automatic loading and unloading.

 I1 is intended to allow continuous and rapid cooking of all foodstuffs in large quantities, either by frying, steaming or boiling with loading horizontal and vertical translations and automatic unloading.

 Until now, cooking devices use a particular agent such as oil or water with a fryer or kettle. It was not possible with a single device to obtain either fried foods or cooked by steam or boiling, in addition the quantities of processed foods was limited and large quantities of continuous cooking could not be obtained.

 The device according to the invention eliminates these drawbacks and allows continuous and unlimited quantity cooking of food ready for consumption or for deferred consumption with loading, horizontal translation of loading, vertical translation of distribution and horizontal translation in the enclosure of cooking with extraction at the end of the operation.

 I1 is constituted by the combination first of an upper loading area of perforated capacity with carrying edges by cables or belts without end of translation, then of an airlock of vertical transfers arranged at each end and finally of a lower sector baking heater with horizontal transfer by cables or endless carrying belts.

In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
Figure 1 shows the device seen in elevation and in longitudinal section in the loading position.

 FIG. 2 represents the same object under the same conditions seen in the cooking position.

 Figure 3 is a perspective view of the vertical elevator with horizontal translational movement.

 FIG. 4 shows an application of the device combined with a refrigerating or other unit based on the same operating principle.

 FIG. 5 represents a perforated basket with carrying handles.

 The device, FIGS. 1, 2, 3, is constituted by a treatment surface 1 with horizontal transfer situated between two airlocks 2, 3 with vertical transfer.

 The cooking tanks 4 are formed by perforated capacities with overhanging peripheral edges to be supported by the horizontal and parallel transfer belts 5 formed by endless cables driven by pulleys 6, 7.

 When a bin reaches the. vertical transfer airlock 2, it is deposited on the horizontal transfer cables 8 located in the lower oil or water cooking capacity 9 heated by the ramps 10, 11 and others.

 At the end of the race, it reaches the vertical transfer airlock 3 which brings it towards the extraction ramp 12.

 The vertical transfer airlocks comprise sliding shutters 13, 14 to avoid the loss of vapor and will be synchronized with a running speed and an elevator assembly 15 formed by two guide columns 16, 17 and a threaded rod 18 driven by the motor 19.

 The mobile gantry consists of two telescopic arms 20, 21 sliding in bearings 22, 23 secured to the driving spacer 24 and driven by the motor 25 driving a threaded rod 26 moving the spacer 27 secured to the arms 20, 21 ensuring a horizontal transfer taking the capacities 4 at the exit of the transporter 5.

 The downward movement brings the basket 4 to the height of the lower transfer 8 and the arms 20, 21 deposit it on the cable 8 located in the cooking sector 29.

 The exit airlock 3 is constituted by the same apparatus (fig 3) and takes the capacity 4 to position it on the extraction chain 12.

 The cooking appliance 30 can be positioned next to a refrigeration unit 31 or any other complementary appliance for storing cooked foodstuffs.

 These refrigeration devices being based on the same functional principles of horizontal transfers with vertical elevators.

 Baskets 4 and others can be perforated or not, depending on the cooking method used.

 Finally, a set of controls 32 makes it possible to automate the speed of transfer feed by belts 5 and 8, the vertical and horizontal transfer times of the elevator 15.

 The speed of the belts 8 varies according to the cooking times and the temperatures of the ramps 10, 11 as well as the nature of the agent used, water or oil or steam.

 It is possible to add a washing machine to the entrance and to automate the positioning of the trays on the power transfer. Chimneys for evacuating hot or burnt gases (33) are provided at the top.

 All cooking modes can be used, gas, electricity, microwave, etc ... for refrigeration: CO2 nitrogen compressor cold.

 These same horizontal transfers in superimposed or even juxtaposed capacities depending on the applications can be used for the manufacture of preserves or the like.

 The machine being equipped with armored resistors with a tangential turbine to heat the vapors and the enclosure to avoid condensation.

 The tunnel and the loading area of the baking trays are very tightly insulated to prevent the waiting products from being reheated, which would harden the vegetables, etc.

 The machine is connected to the water network with a constant level.

 The oil in the fryer will be continuously filtered and recycled. An oil reserve will compensate for the losses and will be at constant level.

 However, the shapes, dimensions and arrangements of the various elements may vary within the limit of the equivalents, like the materials used for their manufacture, without changing the general conception of the invention which has just been described.
