THE INDUSTRIAL INVENTION WITH THE TITLE: »MACHINE TOII COOK PASTA, RICE AND OTHER FOOD PRODUCTS "

Made in the name of: NILMA di Nobili Pietro, based in: PARI-IA, Via Zacconi 2k Nationality: Italy

Submitted on: July 25, 1978 under claim from Priority from Italian patent application no. 261 ^ 3 A / 77 dated July 26, 1977

The present invention relates to a machine for cooking pasta of any shape and format, as well as rice and others Food products.

It is known that so far the koclaen of noodles and of Rice was made in pots, more or less according to the amount that should be cooked at the same time were extensive. In these crocks, the cooking water was first brought to the boil and then the amount of it was added cooking product introduced, stirring means mechanical or manual devices. During the boiling process, the water gradually became rich the strength released by the product. After the end of the cooking process, the product was separated from the water, by draining the latter.

This conventional system of cooking pasta and similar products turns out to be more than just unfavorable from your point of view of rationalization and automation, but it also has various other disadvantages.

First and foremost, it is uneconomical in terms of Water consumption and the consumption of energy that is necessary for heating the water, because that water enriched with starch can no longer be used for further cooking purposes »,

In particular, when it comes to cooking large amounts of product in repeated operations, as is the case in public kitchens, hospitals, canteens , etc. , the above disadvantage turns out to be very serious and does not only involve a waste of water and energy , but also a significant loss of time.

Another disadvantage is given by the systems with which the water and the product are mixed during the cooking process. Large quantities of product can only be mixed by hand with difficulty, which is why mechanical systems are necessary that not only consume energy for their functioning, but also do not allow the product to be stirred gently, but lead to it being broken in itself and thus loses its essential advantages. On the other hand, in the absence of an effective mixing process, the product can stick together or form lumps, especially at the beginning of cooking, so that even cooking is again not guaranteed.

The purpose of the present invention is therefore to realize a machine for cooking pasta and similar products, in which the disadvantages of conventional cooking systems are eliminated and which are ideal for a rationalization and automation of the cooking process is suitable. To achieve this end, the invention provides a machine which consists of a first tub provided with a drain collector located at the bottom; is a second tub with partially perforated walls and intended to receive the product hung in the first tub so as to form a space around the submerged portion of the second tub; a circuit for supplying the upper part of said space with preheated water; a water circulation between the space and the interior of the second tub, this circuit being a pipeline for extraction of the water from the upper part of the space, which is connected to the suction part of a circulation pump is; a filter for the starch in the water, the at the inlet part with the pressure part of the mentioned circulation

Through the pressurized water circulation line and the arrangement of the nozzle or nozzles inside the second tub, that will be in it along with the water The product contained and in the boiling state is set in a rotational movement and therefore more cautious and continuously stirred without resorting to manual or mechanical stirring devices must, so that in this way the ideal temperature and heating conditions are created that a Allow cooking within short periods of time without the risk of sticking or the product leads to the formation of tubers. During the cooking process, i.e. after filling the first tub with water up to the predetermined level, after heating the water to the desired temperature and after the Entering the product to be cooked into the second tub, the machine works with a partially open circuit: in fact, there is a continuous drain of the starch infused water from the drain header intended. This water is automatically replenished from the clean and preheated inlet water. After the starch-enriched drainage water is replaced with clean water, it results in support also through the filter, a complete cleansing of the cooking water from the starch. The percentage of the Water drained away during boiling should expediently be around 10% of the contents of the first tub be.

detailed description of a preferred embodiment denormiien, with reference to the drawings is taken where:

Figure 1 shows a schematic view of the machine half in vertical longitudinal section and half in side view, and thy can be seen, the figure? a vertical (cross-section corresponding with H-II indicated in Figure 1 Verlatif. As apparent from the figures of the drawing The machine for cooking pasta and similar food products comprises a floor-standing frame, generally indicated by 10. The frame 10 holds a first pan 11 of generally rectangular horizontal shape, the bottom of which forms a drain collector 12.

In the tub 11, a second tub 13 is held hanging, which is intended to contain the product to be cooked. This second tub 13 has essentially an oval-cylindrical cross-section (see Figure 2) with a longitudinal wall 14 which extends vertically upwards extended and with another longitudinal wall 15, the one forms towards the inside of the tub facing edge. The head-side walls of the tub 13, as well as the wall IG and finally an elongated median of the At the bottom of the trough 13, perforated areas are indicated schematically by 17 and 18, respectively. The diameter of the holes is chosen in such a way that the food product to be cooked cannot pass through, but possible fractions of it can, such as' small pieces of broken pasta and debris that may be in the product. The total number the holes is not important, it is sufficient that there is an effective flow of water with the impurities through them and with that of the product from inside the tub 13 into the entire immersed part of the tub Penetrate gap 19 separated starch can.

The tub 13 is fixed in the tub 11 by means of arms 20 which are connected to a rotatable shaft 21 in the frame 10 are connected, held in a floating state.

There is also an outer edge. 22, the one with the tub 13 is firmly connected, frame on a part 23 of the frame when the tub 13 is in the submerged position in the tub 11. When you get the wave 21 set in rotation by means of suitable aids, not shown here, it is possible to use the tub 13 in a tilted position (as in the Figure 2 shown by a broken line), so as to remove the cooked product and to ensure any dripping through the holes in the tub.

A likewise tiltable cover 2k, which is carried by brackets 25 fastened to part 23 of the frame structure, can cover the tub I3 on the upper side (see FIG. 2, whole lines).

At the upper edge of the tub 11 and inside the space 19, a feed collector 26 is arranged all around, the holes and slot of which are directed towards the underside of the space for the outlet of the water. This connection 26 is connected by means of a level control valve 27 (for example a float valve) to a line 28, which in turn is connected to the water supply network via a water heater 29 and a salt dispenser 30. A pipe 31 extends from the top of the intermediate space 19 and is connected to the suction pipe of a circulation pump 32 fastened to the frame 10. The outlet of this pump is connected to the inlet of a three-way valve 33 of which one outlet is connected to the inlet of a filter, which is generally indicated by 3%, while at the other outlet a pipe 35 is attached into which the outlet line of the filter opens . The tube 35 leads via a control valve 36 to a terminal with a quick-action coupling 37 x> in which the end portion of a ik in the interior of the tub 13 and that on the vertical wall thereof (see Figure 2) nozzle mounted automatically engages when the trough 13 is in the immersion position. On the same wall Ik could also have more than just one nozzle, in parallel

Way to the terminal 37 arranged to be provided. The nozzle 38 is towards the lower cylindrical part of the Trough 13 directed towards and the jet of water emerging from it (pressurized by pump 32) causes a rotation of the water contained in the tub 13 and the boiling water contained in this water Food product, creating a continuous and gentle mixing process of the product itself is effected.

The filter 3k (see FIG. 1) consists of a cylindrical container and a lower conical part which forms a clarification chamber 39. The inlet line of the filter coming from the three-way valve 33 opens tangentially only a little above this clarification chamber.

In the middle part of the cylindrical container is the filter element kO , which rests on an annular plate kl. The cylindrical filter insert kO separates the central area, which is connected to the lower clarifying chamber 39 i * ¹ , from the annular peripheral area, from which the outlet line connected to the pipe 35 extends. A lid k2 closes the cylindrical container under the action of pressure at the top. In order to keep the surface of the filter element kO clean, suitable scraping devices can be provided (which are not shown in the drawing).

The filter insert is made of a material that is suitable for retaining the starch suspended in the circulating water. This strength collects in the lower conical chamber 39 to which a valve kj is connected, which leads directly to a drain kk .

In addition, a pipe 45 coming from the drain collector 12 of the tub 11 and an overflow drain pipe k6 coming from the intermediate space I9 are connected to this drain kk. The pipeline k5 is connected to the outflow kk by means of a valve k7 which regulates the outflow.

Finally, it should be noted that this is in the tub

contained water very quickly by means of heating elements 48, which are shown in Figure 1 only scheraatiscli and which can work with gas, electricity or steam, to the desired temperature (Boiling state) brought and can also be kept on this.

The functioning of the machine described results as follows.

With the drain valve 47 closed and the circulation pump 32 at a standstill, the tub 11 is preheated with and suitably salted water, which by means of the pipeline 28 and the valve 27 from the water supply network comes, filled until the predetermined level is reached, at which point the valve 27 is automatic prevents the inflow of further water. After the tub 13 through the holes 17, l8 with the space 19 is connected, also arises inside the tub 13 is the same level.

With the help of the heating elements 48, the water is now brought to the boil very quickly and is then connected to it into the tub I3 the too. boiling amount of product introduced, the cover 24 is closed and the circulation pump 32 is now put into operation, the three-way valve 33 must be in the position shown in Figure 1 and adjust the valve 36 in this way is that a suitable intensity of the output from the nozzle 38 escaping water jet is reached. At the same time, the drain valve 47 is also partially opened continuous water drainage from the drain collector 12 to achieve, whereby automatically a continuous flow of a corresponding amount of pure Water is effected through the valve 27, the clean water flows into the space I9 des Collector 27 and pushes the solid impurities of the product in the boiling state in the direction to the drain collector 12, which through the holes 17 and 18 get from the tub I3 into the space 19. Together with some of the strength, these arrive Impurities through the valve 47 to the drain and the drained water is replaced with other clean water.

The water returned by means of the circulation pump 32 is cleaned in the filter 34, which is a further part retains starch, so that there is an almost complete elimination of starch from the cooking water comes.

The percentage emptied during the cooking process Water is expediently adjusted to approximately 10% of the contents of the tub 11.

In the filter 34, more precisely in its lower clarification chamber 39, the starch separated from the circulating water collects after the valve 43 is normally closed. For the periodic cleaning of the filter and the removal of the collected starch, an operation which can also be carried out during the cooking of the product without having to interrupt the movement in the tub, it is sufficient to open the valve 43 and the three-way valve 33 in that position in which the water coming from the pump 32 flows directly into the pipe 35. Under this condition, a part of the TJmlaufwassers emerges from the tube 35 to the filter 34 and flows through the filter cartridge 40 in the opposite direction to that normal, and then exit through the valve 43 and the strength of the chamber 39 ^to remove "

The water jet that flows through the nozzle 38 (or through the nozzles, in the event that several are provided) Entering tub 1-3 causes a vortex-like rotational movement of that contained in the tub itself and the water and product masses that are in the boiling state and thus a continuous, homogeneous and at the same time careful stirring process of the product, without having to resort to mechanical aids. After the cooking process is finished, the The lid 24 is lifted up and the tub 13 with the cooked product is removed from the tub 11. Now one lets drain the water through holes 17 and 18 of the tub. Subsequently, by acting on the shaft 21 using suitable aids a further lifting and tilting of the tub 13 causes

(See the position indicated by the dashed line in FIG. 2 ) in order to be able to remove the product.

The Koclivasser remaining in the tub 11, which is practical Once the starch has been removed and the temperature is still high, another amount of product can be cooked can be used without having to drain it from the tub 11.

The machine according to the present invention has no Doubt any merit around the cooking process of food products to streamline and automate.

In fact, thermostats can be used for automatic regulation the cooking water temperature can be provided, there can be timers for controlling the cooking process built in and all operations programmed and aligned in an appropriate manner. All of these options undoubtedly have their importance when you consider that this machine is used in large kitchens, canteens and similar establishments should be used in which it is very important that the work is carried out to the maximum To rationalize the extent and make it economical, without affecting the quality of the cooked product delivered.

But even if one disregards such a programming of the operations performed by the machine, In any case, the basic advantages achieved must not be overlooked, namely the continuous cleaning of kocli water of starch and the automatic homogeneous Stirring process of the product in the boiling state.
