Frying machine, working under pressure, is used for cooking food (such as meat) in the tank with the use of edible oil. Food and edible oil in the frying apparatus is brought to a high temperature, the pressure support is high enough not boiled away the water contained in the apparatus. With this method of cooking food can be very hot and juicy. Frying machine, working under pressure, usually used on food plants, and it can contain fire-fighting system. In particular, the nozzles are positioned to direct the fire of the reagent on the center of the vessel, at the time when the cover is open frying apparatus operating under pressure. Although this design reduces the possibility of fire in the frying apparatus operating under pressure, it is desirable to have the best design.

These embodiments of the invention relates to fire-fighting system for the apparatus, such as deep-frying apparatus operating under pressure. Frying apparatus may contain oven capacity (which are the food and edible oil) and a lid for closing the oven capacity. Cover frying apparatus may have three positions: fully open position, a closed/unlocked p is the position (lid frying vessel is closed, and ventilation oven capacity through hole and a closed/locked position (frying container tightly closed for cooking). Fire alarm system frying apparatus includes a reservoir for fire reagent tubing connected to the reservoir, and one or more nozzles connected to the pipeline and located so as to direct the fire of the reagent in the oven capacity, when her cover is not in the fully open position (for example, when the cover is in the closed/unlocked position).

For example, when the cover is closed, between the frying tank and the inner part of the cover can be formed free space. According to one aspect of the invention, when the cover is in the closed and unlocked position (with a hole leading into the free space of the oven capacity and designed for ventilation capacity), the nozzle may be located outside of the lid and oven capacity thus to direct the fire of the reagent through the hole in the free space of the oven capacity. The nozzle may have a horizontal dispersion (e.g., fan), so that through with crack-like hole were more fire reagent. As another example, the nozzle may be featu the wife so to fire the reagent was received in another opening leading into the frying container when the cover is in the closed/unlocked position. In particular, oven capacity may have a hole for the overflow tube drainage, which leads to a drain. The nozzle may be positioned in such a way as to enter the fire reagent inside the free space of the oven capacity through the hole for the overflow tube drainage.

Further, the sprinkler system may contain one or more nozzles connected to the pipeline and thus arranged to direct fire the reagent in the frying tank when the cover is in the fully open position. One or more nozzles arranged to direct the fire of the reagent in the frying container when the cover is in the fully open position, may differ from one or more nozzles arranged to direct the fire of the reagent in the frying container when the cover is not in the fully open position, according to several parameters, including: (1) position (such as position in the direction of x, y and/or z); (2) nozzle type (for example, fan-shaped or conical); and (3) the direction of release of the reagent injectors (for example, up or down). Thus, one or more nozzles, RAS is than necessary, so to direct fire the reagent in the frying container when the cover is not in the fully open position, are designed to work either alone or in combination with one or more nozzles arranged to direct the fire of the reagent in the frying container when the cover is in the fully open position. Thus, the sprinkler system can better fight the fire into the frying apparatus operating under pressure.

In General, the preferred embodiments of the invention described below relate to the fire protection system for a cooking apparatus, such as deep-frying apparatus. Fire protection systems can be applied in many frying apparatus, including frying apparatus operating under pressure. Shows two examples frying apparatus operating under pressure: frying system containing one rail for lifting the lid, located at the center (shown in figure 1-3) and frying system containing two guides for the lifting of the lid (shown in figure 5-7). Specific examples of frying systems that can be used with sprinkler system frying apparatus include models 690, 691, 692 companies Henny Penny (frying system containing one e.g. is engaged for lifting the lid, located in the center) and model 580, 581, 852, 590, 591, 592, 680, 681, 682 the company Henny Penny (frying system containing two guides for lifting the lid). Models listed are included solely for illustrative purposes. Can also be used frying devices from other manufacturers and other structures.

In accordance with the following detailed description, sprinkler system can provide protection from fire when the cover is in the fully open position (such as the fully open position of the lid) and/or in the closed position. For example, the cover in frying system can be in one of three positions: (1) a fully open position; (2) fully closed and locked; and (3) closed and vented. The position of the cover can be fully open when charging grid and the frying basket of the apparatus are in the fully open position. As one example, the intermediate position between the fully open position and fully closed and locked position) can lead position when the cover is fully closed and the handle of the frying apparatus operating under pressure, unlocked, creating a hole or chink, through which, therefore, leaves of pairs of free space frying capacity. In this position, the load is provided for the latch may be locked in position. As already mentioned, some piece frying apparatus can be opened for ventilation oven capacity. For example, for ventilation oven capacity frying apparatus can be opened in the rear part of the frying apparatus, forming a slot of a size in 1/4 inch (0,63 cm).

Typically, fire-fighting systems are to extinguish the fire in case when the cover frying apparatus is in the fully open position. However, the risk of fire remains and then, when the lid frying apparatus is not in the fully open position. For example, when the lid frying apparatus partially opened or is in position for ventilation oven capacity frying machine, frying machine exposed to the risk of fire (e.g., due to leakage of bubbling oil through the hole or the ingress of air into the tank).

Fire system shown in figure 1-7, can be used to reduce the risk of fire when frying apparatus is in the fully open position and/or is not in the fully open position.

Figure 1 shows a front view of the frying system containing one rail for lifting the lid, placed in the centre, with cover 110 in the open position and one guide, depicted as element 130. Op the food frying apparatus and fire system indicated by the element 100. Figure 2 shows a side view of the frying system, shown in figure 1, with the cover shown in the fully open position and in the ventilation position (the position of the ventilation cover are shown by dashed lines). Figure 3 presents a top view of frying system, shown in figure 1.

Figure 1 shows the "ground block 120, which can be installed on the frying apparatus. For example, the branch unit 120 may be installed, for example, on the rear parcel frying apparatus. The branch unit 120 depicted in FIGU-B. Nozzles can be attached to the frying apparatus using set to set of nozzles, which may include nozzles, adapters for swivel nozzles, air caps, nozzles, ground block with fasteners, locking nipple, stainless steel pipes of different lengths and elbows. Nozzles can be located in many places ground unit to direct fire reagent on different parts of the frying apparatus. Fire reagent may be any substance that can be used for containment of fire or decrease its action.

Figure 2 and 3 shows two nozzles 210 and 220 used in fire protection system. Figure 2 and 3 shows two nozzles 210 and 220, for illustrative purposes only; may the be used more or fewer nozzles, as will be discussed in more detail below. At least two nozzles in the system can differ from each other by several criteria, including: position (e.g. the position in the direction of x, y and/or z); the type of nozzle and the direction of release of the reagent (for example, the direction up or down). As shown in figure 2, two nozzles 210 and 220 are in different positions (positions vary in the z-direction) and have opposite directions of release reagent (up and down). More specifically, the nozzle 210 tee block can be placed so that its tip is located at 16 inches (40,6 cm) above the surface of the base frying apparatus and 5 inches (12.7 cm) inward from the right side of the rear casing of the device. The nozzle 210 may be directed down and to one side, for example, an angle of about 45° down (shown in figure 2) and at 45° inside (shown in figure 3)to release the reagent into the center of oven capacity. In another example, the tip of the nozzle 220, operating in a downward direction from the ground block to the base of the frying apparatus may be located within 2 inches (5.1 cm) from the rear side of the oven capacity and 8 inches (20.3 cm) inward from the right side of the rear casing of the device. The nozzle 220 may be directed upward, as shown in figure 2. Thus, in the case when the cover 110 frying up the Arata is partially closed, as when frying tank 140 is vented through the opening 240 in the back, fire the reagent may be directed through the opening 240 in the back, which is not closed and is under the cover 110. Thus, fire reagent may be introduced into the free space frying vessel 140. Although figure 2 shows that the aperture 240 is located in the back, it can be positioned along one or more sides of the oven capacity.

Further, the first nozzle 210 and the second nozzle 220 may belong to different types. For example, the first nozzle 210 may have a narrow shape, for example conical. The second nozzle 220 may differ flat spray, for example a fan. As mentioned above, the nozzle 220 may be flat spray, and the spray can be horizontal relative to the rear edge of the cover frying capacity.

Each frying apparatus may be provided with a reservoir (not shown)containing at least a 3.0 gallon (0.01 m³) fire reagent ANSULEX® low pH. To connect with the tank, producing a release of the reagent through two single jet nozzle, use the pipeline. As an example of the pipeline shows the element 230. Two nozzles 210 and 220 can operate simultaneously, synchronously releasing fire reagent.

On figa and 4B, the image which are a top view and a side view (respectively) of the area of the branch unit 120. The branch unit can be attached to a frying apparatus using is shown in figure 4A holes 410 under the screws. Additional holes can be used as the inlet holes (inlet fire reagent through a pipeline in the ground block 120), and as the outlet openings of the nozzles. The branch unit 120 may also contain a pipe, shown in figa and 4B dashed lines. For example, on FIGU shows the connection to the pipeline with a normal pipe thread (American standard) 3/8 inch (0.95 cm).

Figure 5 shows a front view of the frying system containing two guides for lifting the lid, the lid is in the open position. The combination of a frying apparatus and fire fighting systems are depicted as element 500 with a ground unit 510 and oven with a capacity of 520. Figure 6 shows a side view of the frying system, depicted in figure 5, with the cover shown in the fully open position and in the ventilation position. 7 depicts a top view of the frying system, presented in figure 5.

Similarly, the nozzle 210, the first nozzle 610 on 6 and 7 may have a narrow shape (e.g., conical) and be in the top position. Similarly, the nozzle 220, the second nozzle 620 may be a type of flat spray (e.g., fan) and is the bottom position. As shown in Fig.6, the nozzle 610 and 620 can be located in different places of the frying apparatus.

For example, the nozzle 610 in the upper position can be located such that its tip is 16 inches (40,6 cm) up from the surface of the base frying apparatus and 5 inches (12.7 cm) inward from the left side of the rear casing of the device (as opposed to the right side, as shown in figure 3). The nozzle 610 may be directed downward to release the reagent into the center of oven capacity. As another example, the tip of the nozzle 620 in the lower position, producing reagent down the tee block 510 through a pipeline 630 on the basis of the frying apparatus may be located within 2 inches (5.1 cm) from the rear side of the oven capacity and 8 inches (20.3 cm) from the left side of the rear casing of the device (as opposed to the right side, as shown in figure 3). As mentioned above, the nozzle 620 may be a type of flat spray, and spraying can be done horizontally relative to the rear edge of the cover oven capacity. The nozzle 620 may be directed upward, as shown in Fig.6.
