Strain the oil using a special filter (it is a funnel of dense non-woven cloth or paper) or fabric. This way you can remove the excess cake, seeds and other impurities. Do not use either during production of the oil, during filtration metal containers; give preference to inert materials such as stainless steel, mild steel and aluminium with epoxy coating, glass, food grade plastic.
Cedite oil immediately, because the impurities contribute to the rapid deterioration of the product. Please note that many Housewives instead of filtering using a technique of defending the oil. Close the tank with oil tight lid and leave for a day. During this time, the oil may stratify, light particles will rise to the surface, and at the bottom appears muddy sediment. Remove all the peel and carefully pour product into a clean container. You got unrefined oil.
Keep this oil only in the dark. Do not place in the refrigerator and never cook on it, as formed at high temperature toxic compounds.
However, strain the oil enough; it is important to understand that in obtaining oil from seeds pressed into it, in addition to the main group triglitseridov pass structural lipids, which determine the characteristic color, smell and taste, as well as water, paraffins, waxes, polycyclic aromatic hydrocarbons, residues of herbicides and pesticides. It is important to clean the oil from these components.
For deep cleaning use methods of deodorizing and refining of oils. Both these processes are difficult for home reproduction and require significant knowledge of chemistry substances. Ropinirole oil with alkali. Deodorize, dry steam treating at a temperature of 170-230 ° C in vacuum conditions. To do this, use a custom installation, in the VAT where you pour the oil and the tank has the desired amount of water. Deodorized oil is completely ready in 3-5 hours.
Keep vegetable oil at a temperature not above 18 degrees; refined - 4 months, whether oil - 2 month.
Advice 2: How to clean aluminium
In everyday life we often have to deal with aluminium products. It can be door and window frames, kitchen utensils, hardware furniture, aluminium paneling. Occasionally have to clear the aluminum items from contamination. In order to clean more effectively, use some tips.
You will need
- All-purpose detergent, trisodium phosphate, washing powder, liquid WD-40, sponge, water container, rags, a sponge made of thin steel wire
For cleaning aluminium door and window frames, use a universal detergent, for example, Domestos. Problems with cleaning does not arise, since these products are provided with durable corrosion-resistant coating, white, brown or stylized bronze. Also to remove dirt from the frames use means for washing of glasses.
Exterior aluminum paneling walls clean at least once a year. Otherwise, the lining starts to cover the RAID, similar to chalk, and then it appears dark, no reduced spots. Clean plating trisodium phosphate, which can be purchased at a hardware store. Mix trisodium phosphate with warm water in the proportions specified in the instructions for use. The treatment of aluminum surfaces need rubber gloves and protective glasses.
For the second method of cleaning the aluminum exterior, use a washing detergent (for example Tide). Dissolve a quarter Cup of detergent without bleach in a bucket with 8 litres of warm water. Moisten a sponge with the solution and wipe the aluminum. After that, rinse the surface with water from a garden hose.
The third method for cleaning aluminum surfaces exposed to the sky will require the use of special liquid WD-40. Apply the liquid to the aluminum with a rag or by spraying. After a few minutes wipe the surface with sponge made of thin steel wire. Do not push hard on the surface there are no scratches. Then wipe oily liquid with a rag. Metal with this method of cleaning becomes lighter and starts to Shine.
