Description

Title of Invention: HANDHELD FRY OIL FILTRATION MACHINE

Disclosure of the invention:

• Background of the invention and prior art:

The vegetable oils filtration technology used in frying process is of the most important technologies used in different food entities which mainly depend on frying oil in their production. This technology is of great demand due to its positive effect in maintaining the quality of oil during the many times re-uses of the oil for frying. Such technologies include the handheld small machines which are placed inside the frying pan sink in the oil. However, such machines are of weak demand due to their inability to solve many problems such as their direct contact with the electrical power, electrical wires installation, and their inability to make Micro Filtration for the oxidized oil. Removing the tarnish seen by the eye is done by pushing the oil from the frying pan and passing it through filter paper or metal grid and returning it directly to the frying pan basin.

• Problem or deficiencies of the prior art:

The handheld portable frying oil filtration machine in prior arts filtrates the oil by adding filtration paper or without filtration paper. It depends on a zigzag metal grid similar to the saw teeth. The machine pushes the oil from the frying pan and passes it on the paper or the zigzag grid to purify it from the suspended tarnish apparent to the naked eye and is returned directly to the frying pan. The machine does not perform an accurate filtration to the oil (Micro Filtration) in terms of minimizing the Free Fat Acids (FFA) resulting from the oxidation processes during the frying or the Total Polar Materials (TPM).

The handheld portable frying oil machine in prior arts, which are designed to be placed inside the frying pan sink (soaked in the oil) at high temperature, operate at 110 or 220 volt and directly connected with the power source by an electrical wire installed over the frying pan , which is full of the very hot oil necessary to filtrate the oil. This imposes a danger threat to the public safety during the process of operating this machine and may cause catastrophic mistakes such as fires that could not be controlled.

The handheld portable frying oil filtration machine in prior arts operates at 110 and 220 volt is not a power saver.

The handheld portable frying oil machine in prior arts only operates if the frying pan bottom surface is flat and this is not suitable for most types of frying pans in the markets which their sinks, depths and heating systems differ. The heating system might be flat or concave or anchored to the sides of the frying pan sink from inside.

The handheld portable frying oil machine in prior arts operates by the system of sucking the oil in the frying pan from the bottom only where the oil suction is performed through the bottom suction fan in the prior arts, i.e., the cold zone, and this takes longer time to complete the filtration of the total oil quantity in the frying pan. The handheld portable frying oil machine in prior arts depends on pushing the oil from the frying pan to internal filtration sink containing a zigzag grid or zigzag filter paper in form of small pyramids with sharp corners of very narrow areas similar to the similar to the saw teeth (Fig.8-B), and cannot comprehend the tarnish, food leftovers and flour .... Etc. from the frying pan oil, especially the big size or big capacity frying pan.

The handheld portable frying oil filtration machine in prior arts does not operate efficiently in case of using additives powder such as magnesium silicates which is used to filtrate the frying oils from the Free Fat Acids (FFA) and minimizing the Total Polar Materials (TPM) which increases the efficiency of the frying oil operation and prolongs its life and minimize its pollution of the environment, which is used by most fast food restaurants as basic material in the oil filtration process.

• What is new in the invention

This invention overcomes all deficiencies and problems in prior arts in terms of saving power by equipping the new machine with l2-volts rechargeable battery that operates for long hours without need to be connected to power supply of 110 or 220 volt; cancels the direct installation of electrical wires over the high temperature frying pan; and avoids the risks of fire and hard wires installation. In addition, the said machine is characterized in that it has built-in cooling system to maintain the electrical units and operate them efficiently. The machine also has two suction system, upper and lower, to push the oil from upward to downward towards the filtration box to save the time and effort in the process of filtering the oil as fast as possible especially when used in filtering big size deep frying pans, in addition to the extinct design of the flat sink which could be anchored to the sink of different types of frying pans of different sizes more stable than the prior arts. Furthermore, this machine is characterized in that lateral arms could be added to give more stability during operation and to work with all types frying pans of different sizes and designs. In addition, the new design of the filtration paper base was developed to add the powder dietary additives, the magnesium silicates used in filtering the vegetable oils in most fast food restaurants all over the world. This machine does not require the user to pour the powder dietary additives in the frying pan sink as this distinct design keeps the powder inside the machine upon addition inside the filtration box which is designed for this purpose and prevents the return of what is picked up to the frying pan again. Also, the distinct design of the zigzag grid filter base in form of cubic chambers can comprehend all tarnish picked up from the oil This machine also has magnetic rulers to withdraw the electrical charges in the oil resulting from the oxidation processes, called the Total Polar Materials (TPM).

The capabilities of this machine to filter the frying oil paramount the prior arts in many aspects in terms of saving power, accurate filtration and speedy performance. It is more specialized in filtering the vegetable oils and withdrawing the oxidation resultants accurately and prolongs the age of the oil in a healthy and sound manner. B. Detailed description of the inventions

This invention is characterized in that it solves the electrical consumption problem by equipping it with light-weight small-size rechargeable 12- volts battery (Fig. 1- 1). It also does not need external electrical connections.

This machine has a charging base designed separately to charge the battery (Fig. 1 - 14). It is also characterized in adding very small air-cooling unit (Fig. 1-5) designed to keep the electrical internal parts (battery, motor, and other internal wires and connections) from the heat transfer from the machine body made of the dietary stainless steel upon soaking it in the hot oil to be filtered where the cooling unit is connected with the machine head lid beneath the filtration openings (Fig. 1-6).

The charged battery is place in its suitable place on the electrical socket (input - +, and output - +) in the machine head lid (Fig. 1-2), then closing the battery lid by the ad-hoc lock (Fig. 1-3). The user opens the filtration box connected with the machine body at the front at 90° downward (Fig. 1-9) and pulls the filtration box lid outwards (Fig. 1- 10). After that, the user anchors the filtration paper to the zigzag grid base (Fig. 2- 1.2) and enters the anchor frame over the filtration paper to anchor it (Fig. 1 - 3). The anchoring frame has magnetic rulers to pick up the polar materials from the oil (Fig. 1-4) to minimize the Total Polar Materials (TPM) resulting from the continuous use of oil. The anchoring frame with the grid base (male and female) form cubic chambers enabling the user to add filtration powder such as magnesium silicates, magnesol, and miracle powder (Fig. 2-5). The user places (the grid base, the filter, and the anchoring frame) as one unit inside the filtration box. Such unit could be carried very easily by a foldable grab handle on each side anchored to the grid base, and installs the lid again over the box and closes it (Fig. 1-9, 10).

After that, the user carries the machine by the grab handles anchored to the sides of the machine body and insulated by thermal Teflon (Fig. 1 - 15) then transfer and put them in the oil in the frying pan sink. The machine is characterized in that it has two arms on both sides (if necessary) removable at 90° to support the machine and be hanged on the sides of the frying pan (Fig. 3- 1, 2). The machine surface is soaked in the oil and it could be placed on the flat frying pan surface. The machine surface has flat frame to reinforce anchoring the machine inside the frying pan (Fig. 1- 16) where the oil level in the frying pan must be at the minimum and maximum level printed on the filtration box cover (Fig, 1- 17, 18).

From the above, the machine has flat lower surface and moveable foldable arms to anchor the machine on the frying pan sides to suite all types of frying pans of different lower and upper designs, sizes and depths.

The user operates the machine by pressing the ON/OFF button (Fig. 1 -4) from the machine face to open the electrical power from the battery to the remaining electrical parts. To start the filtration process, the user presses the FILTER button (Fig. 1 -4). The third button is to operate the battery digital indictor which displays the percentage of the battery charging and the power consumption consummation in the filtration process (Fig. 1-4). Upon starting the filtration process, the 12- volt motor (Fig. 5- 12) rotates at 2200 revolutions per minute (RPM) counterclockwise. The motor is connected with blades rotation shaft by a coupler (Fig. 5- 10) insulated at its middle by thermal Teflon (Fig. 5- 11) to prevent the heat transfer to the motor (Fig. 5- 13). At the end of the rotation shaft there is upper blade having eight blades that sucks the oil from the upper (hot) area in the frying pan into the upper cavity and pushes it towards the filtration box through the upper opening at the front (Fig. 1 -20). The rotation shaft penetrates the layer separating the upper cavity and the lower cavity where it is connected from its end with another lower blade having the same measurement and number of blades of the upper blade but directing downward. It sucks the oil from the lower (cold) zone in the frying pan inside the lower cavity and pushes it towards the filtration box through the lower opening at the front (Fig. 1- 19). It addition, it has two cavities at the base, upper and lower, to minimize the normal filtration time and filtrate the total quantity of oil as fast as possible better than the prior arts.

When sucking the oil from the upper and lower areas into the cavity (Fig. 6) through the rotation of the eight blades counterclockwise, the oil is pushed to the filtration box at the front and the box is moveable at 90° upon opening and closing (Fig. 1 -21).

The filtration box is characterized upon opening that it is in the shape of rectangle when moved downwards (Fig. 1-9) where the filtration unit is anchored inside it. The bottom of this box consists of rectangle openings (Fig. 1- 12) to take out the filtered oil which goes through the filtration unit (Fig. 2) outside the machine and returns it to the frying pan sink.

The filtration box is vertically supported by the machine body from the front when closed and pulled upward (Fig. 1-22), so it is well sealed (Fig. 3-3). When pushing the oil to the filtration box and being filled in full, the machine body (the separator) which supports the filtration box contains upper openings (Fig. 1-8) allowing the return of the oil exceeding the filtration box capacity to the frying pan and reducing the pressure on the filtration unit.

The oil passes through the filtration unit which consists of the following:

Filter base: It is characterized in that its sides are designed in form of digital wave with perforated grid ground having big openings and carrying the filter paper (Fig. 2- 1), (Fig. 4- 1) and having two grabs to facilitate holding it.

Filter paper anchoring frame: It has the same design of the filter base in form of digital wave but it is of slightly smaller size. It does not have grid. It anchors the filter paper (Fig. 4-2) and closes with the base where the frame sides are transversely connected with each other with slices forming baffle to collect the tarnish on the filter paper (Fig. 4-3) and prevent its return backward.

The slices in the anchoring frame are characterized in that they have strong high-heat resistant magnetic rulers encapsulated inside a rod of dietary stainless steel anchored to the frame slices from inside as in (Fig. 2-4) and (Fig. 8, A- l) where these rulers pick up the positive and negative charges and decrease the Total Polar Materials (TPM) reading spoiling the oil and increase the oil quality by reducing the percentage of such materials which form the main factor of spoiling the frying oil. The filtration unit is designed to use the dietary additives powder which is complied with by most restaurants in the filtration processes such as the magnesium silicates, commercially known as "Magnesol" or "Miracle Powder" and others where the filtration unit could be easily filled with this material without need to be added in the frying pan (Fig. 2-5) and (Fig. 8, A- 2) which reduces the Free Fat Acids (FFA) and absorbs the water leaking into the oil. The user also can add additional filtration paper of the active carbon above the main filtration paper to increase the oil purity (Fig. 4-

4).

Upon completion of the filtration process, the user presses again on the FILTER button (Fig. 1-4) and disconnect the power from the battery be pressing on the ON/OFF button (Fig. 1-4) from the machine side.

The conformation of the machine with its all parts and details (Fig. 1) and (Fig. 6).
