Description

Continuous cleaning and degreasing procedure of kitchen extraction and odor neutralization circuits to the external outlet of the corresponding ducts and appliances.

The present invention refers to a device for cleaning and degreasing continuously, without manual intervention, circuits and ventilation ducts and extraction of stale air by cooking and then aspirated by cooker hoods, as well as susceptible ducts or pipes of getting dirty by organic materials. It also allows neutralize odors at the outside (or inside) of the extraction and ventilation pipes of kitchen or any other air outlet from smelly gaseous bodies.

The device according to the invention consists in creating a drizzle of extremely fine water to which it is mixed, in various proportions, a product or products that contain mainly bacteria and enzymes selected for the biodegradation and digestion of fats and organic materials, thus preserving the continuous cleaning of the pipes and tubes to the time that contributes to the elimination of odors avoiding fat deposits inside said ducts, tubes and any other places likely to get dirty (engines of extraction, etc.); essential oils and natural essences for neutralize odors as well as any other product that may Contribute to improve health or hygiene.

The current techniques used to degrease and clean the inside of the extraction and ventilation ducts Cooking are essentially manual or mechanical. They are extremely heavy, expensive and uncomfortable since it is necessary to stop the kitchen operation or other industrial functions during the time necessary to carry out for such cleaning. Be exposes one of these devices in the patent DE-A-19.626.898.

The configuration of the ducts, their route in frequently inaccessible places that may have important lengths makes it virtually impossible clean them, while it is almost always impossible perform some checks, both to assess your degree of dirt to verify the cleaning action traditional.

The possibility of doing so by studying remote control robots inside the ducts with television, cleaning devices and tracks to advance inside dirty ducts, but the prototypes reach employment prices that they are completely impossible to take into account on farms commercial.

The techniques used to eliminate odors they are also heavy, expensive, uncomfortable, cumbersome, sometimes of realization and dangerous use (active carbons, ozone, washing of air, pyrolysis ...).

The invention aims to solve these inconveniences for safety, environment and hygiene, both in the interior as for the neighborhood. It is characterized by different associated technologies:

-

creation of a machine that has for function mix water and products in certain doses, subject said mixture to high pressure while heating it, spread the drizzle mixture, often the finest possible, within the extraction ducts, or of various sizes according to job specifications to perform;

-

water treatment acting on Calcium and magnesium carbonate crystals, microorganisms, the different minerals contained in the water so that the contact at the molecular level of the product and water transformed into extremely fine drizzle be accelerated and achieved as soon as possible the transport state and is distributed in a homogeneous way to everything length of the ducts and surfaces to be treated;

-

selection of biological products emulsifiers and / or biodegradants as well as essential oils, natural essences, aseptic products and others that have beneficial effects for the neutralization of odors, health, Hygiene and several other applications.

The attached principle schemes show the invention with reference to the different principles before cited.

Figure 1 - With feed tank of the mixture.

Figure 2 - Without power supply tank mixture.

The machine (figures 1/2) is composed of water mixing devices of the urban network with the product selected mixed in a tank (9) by pumps dosing (2) proportional, peristaltic or per system venturi Their number will vary depending on the character of the place to treat (1 to 3 in general). A variant of the machine (figure 2/2) consists in performing the direct mixing at the arrival of the tube to the water that directly feeds the high pressure pump (without Deposit). The pump (3) thus fed will put the mixture under pressure (between 25 and 100 bar according to specific needs) and the will transport by means of flexible high pressure ducts (4) with a nozzle or several special nozzles (5) that will adapt to the specific needs of the installation to be treated and will vary in number, flow rate per hour (also depending on the pressure used) and the size of the droplets produced (from 2 to 15 microns up to 50 to 100 microns). The application of water pressure will raise your temperature, favoring the performance of bacteria given the use through the nozzles (5) of a lower flow rate than the one exerted by the pump (3) and to be carried out by means of water recycling not used in the tank keeping the mixture at the temperature of battery performance.

Flexible high pressure ducts (4) they will allow more sinuous routes, without limit of distance, with possibility of placing the nozzles (5) in the most appropriate places, whose quantity and choice will be determined by the power, the Extraction volume, travel and length of the ducts. A programmable control unit (6) allows, through a system of solenoid valves and timers integrated by several circuits, All adjustment possibilities:

-

Product dissolution percentage in water, operating the pump or dosing pumps.

-

7-day watches over 7, 24 hours over 24 that allow to program the operation of the machine and of its different circuits at the selected hours.

-

Adaptation of the operation of the feeding circuits of the nozzles (5) according to the periods in that the procedure needs more power.

All such elements are enclosed in a protection and safety cabinet.

The water treatment device (1) of food is intended to obtain a favorable contact water from the active components of the product to the water, to the transformation of the sprayed mixture, then distribute evenly these active component media to fats and other organic materials to all along ducts as well as stale air. For it we will use a procedure that will act on carbonates of calcium or magnesium contained in the water, making forms subnanic calcareous by saturation of calcium ions. Such forms they will form a substrate of expanded flake crystals, very numerous and very light, octagonal that serve as the basis for effectively transport neutralizing elements, bacteria and enzymes, increasing the contact surface. This equals delay the propagation velocity of transported water vapor by extracting the air that contains the active products and Give you more time in contact with the air and the materials to be treated. This phenomenon is amplified due to the decrease in density of the bodies which still gives more contact possibilities so much in the air transported and swirled to be distributed over the inner surfaces of the ducts. This is obtained by running the water through cartridges containing two materials of opposite signs in order to create an electromagnetic field (iron and catalyzed magnesium).

The selection of active biological products, essential oils, natural essences (or others depending on the required applications) is performed by its capabilities degradation of fats, digestion of fats and organic materials, odor neutralization, environment aseptization by effect natural (essential oils).

The procedure will also allow dispersion. of products that benefit health and hygiene in the circuits Indoor ventilation Product development Biotechnology guarantees a constant evolution in the possibility to adapt our selection to the specifications of the problems to treat
