Device for cooking (sterilizing) food cans. Patented in Deutseben Reiche on June 21, 1919.

The invention relates to a device for sterilizing food cans.

The invention solves the problem, a known for uninterrupted Established in operation, closed on all sides

Cooking vessel in which guide tracks are arranged for the cans rolling through the vessel, and which is provided with a jointly driven inlet and outlet device at the ends of the guide tracks

is to first load with cans in the desired number, after the cooking vessel has been filled with cans, the removal and, if necessary, the simultaneous further introduction of the cans to be regulated and to effectively prevent bulging (crowning) of the cans when leaving the cooking device. This is achieved in that an engageable clutch is switched on in the drive of the outlet device, which in the engaged state allows a common rotation of the inlet device with the outlet device, in the disengaged state, however, a rotation of the inlet device alone. As a result of the arrangement of this coupling, the cooking vessel, which is provided in a known manner with a fixed guideway for the cans, can be filled with the cans to be sterilized in the time sufficient for cooking, expediently moderately controllable, whereupon one is already finished through the outlet device cooked can is discharged, while at the same time a new can is introduced through the insertion device into the cooking vessel. It is expedient to attach an automatically engaging clutch in such a way that after a certain number of revolutions of the insertion device, which are required to fill the cooking vessel, the outlet device is automatically set into rotation, whereby the uninterrupted operation of the device is initiated The multi-chamber tap of the outlet device can be provided with so many recesses, known per se, for: receiving the cans to be discharged, 1 that each can has enough time to cool down from the exit from the cooking space to leaving the outlet device during uninterrupted operation in order to reduce the harmful internal pressure in the can has This is prevented, 'that the can itself after cooking at the' bulge leaving the device (cambered) to support or mitigate the cooling is arranged in the housing of _the. multichamber cock of the exhaust inlet nozzle for introducing a coolant. - or '■ heating means through which each passed, a can-containing recess of the faucet is charged with the required means j in each case. The same device can: also be used with the insertion device! when you want to preheat the cans to be brought in.

In the drawing, an exemplary embodiment of the invention is shown in FIG. Fig. Ι and 2 shown in vertical section and in i side view. Fig. 3 shows a | Detail to AbTj. 1. '

One in a manner known per se with steam; ' let in and water drains provided cooking chamber c in rectangular or any other shape has slightly inclined, superimposed roller tracks d, which together with transition pieces e and cover walls 5 in a known manner a channel-like, from the 'upper to the lower chamber parts reaching slide for the cans to be cooked h form. At the top of this slide or roller track d is a sealing introduction device, also known per se, eg a six-chamber tap f, and at the bottom an outlet device g of the same type is connected, so that the cans h introduced above, as shown in Fig. 1, are automatic, due to its own weight, the. Cooking chamber c; pass through and fall into the outlet device g, which discharges them. The walls δ prevent the cans from climbing on top of one another as they pass through.

The taps f ¹ and g ^{1 of} the multi-chamber introduction and outlet devices f and g are driven in the version shown by a back gear i , the shaft i ¹ of which is coaxial with the rotating shaft g ² of ^{the tap g 1} and with the shaft f ² of the cock f ^{l is} connected by two bevel gear sets m and I and a spindle k . As the intermediate gear i revolves, the insertion device f is continuously moved with it, inserting six cans into the cooking chamber c during each full rotation. The outlet device g, however, is connected by an engageable and disengageable coupling with the back gear i or the insertion device f, so that the cans can be removed from the chamber c within certain limits independently of the introduction of the cans into the chamber and thus the Can regulate the cooking time. This coupling is designed as follows:

The rotary shaft f ^{2 of} the six- ^{chamber valve f 1} carries a worm s (Fig. 2), which ^{engages in a worm wheel s 1} , with which a graduated disk t is connected in a known manner. This index disk has twelve insertion holes distributed around the circumference for a stop pin t ¹ , furthermore the transmission ratio of the worm gear s, s ¹ is chosen so that the index disk makes one full revolution in one hour, which forms the normal cooking time. Accordingly, by inserting the pin t ^1, the cooking time can be regulated in steps of 5 to 5 minutes as follows. A lug n ^{x of} a bolt η protrudes into the path of the insert pin t ¹ rotating with the index plate t and locks a weight bar ο in its raised position (Fig. 2). One arm of an angle lever q rotatable about a fixed horizontal pin q ^{1 is} connected to this rod 0 , the other arm of which is connected

—-Τ-

engages on the displaceable claw r ^{1 of} a claw clutch r. Through this coupling the rotating shaft ² may g of Sechskammefhahnes g ¹ coupled to the countershaft i ¹

'5 or be switched off by it. The Kup. pein and thus the turning of the outlet device g takes place when the insert pin t ^{1 of} the partial disk t hits the bolt η and removes it from its blocking position, that is to say in the

ίο Moments when the predetermined number of doses is introduced into the cooking chamber c or the predetermined cooking time has been reached. From this point on, the insertion and discharge devices f and g work together in such a way that each insertion of a can h corresponds to a removal.

At the beginning of the can removal there is, as the still cold or only a little; warmed outlet device g immediately precipitates the steam that gives the hot can in the faucet chambers, the risk of the cans bulging. On the other hand, it is to be expected that after the outlet device g has been warmed up in the company, the cans in the chamber tap g ^{1 will} not cool down sufficiently quickly, so that the crowning can also take place at the moment when the can is exposed to the outside air (outlet nozzle g ³ in Fig. 1) comes into contact. These dangers can be countered by heating and cooling the cans. To achieve this, a line u is arranged, which is connected to the steam space of the cooking chamber c (or a special steam source) as well as to a cooling water line ν with the inclusion of shut-off devices u ¹ , u ² (Fig. 1). The common heating and cooling line u is also connected by short pipelines w ¹ , w ^z , w ³ to that side of the chamber which the hot cans h coat when they are removed. The same device can also have the insertion device f .

It is expedient to relieve the outlet device g by a slide which regulates the falling of the respective bottom can h and which absorbs the pressure of the can column. In the exemplary embodiment shown, this slide consists of two plates χ (Fig. 1 and 3) suspended from a two-armed rocking lever x ¹ , which are guided vertically and whose clearance corresponds to the can diameter. By means of a crank y, which is rotated by the shaft g ^{2 of} the six- ^{chamber valve g 1} with a six-fold ratio, the two slide plates χ are alternately raised and lowered, whereby , as the valve g ¹ continues to rotate by one chamber division, they first let a can fall down and at the same time block the other cans and only then, with reverse movement, allow the entire can column to roll by one can diameter. The chamber cock g ¹ is completely relieved.
