Compositions for an methods of lubricating carcass conveyor
An improved method for applying an electrically charged lubricant on an oppositely charged carcass trolley in a meat packing plant meeting the requirements of (1) adequate lubricity, (2) “drip-resistance,” (3) safety, (4) rust resistance, (5) economy of manufacture and use, and (6) the ability to be removed by cleaning methods is provided by preparing a mixture of mineral oil, a fatty acid, a silicone oil, and a polybutene, each being acceptable for incidental contact with food.
1. A method of applying a lubricant on conveyor machinery used in a meat packing plant, wherein such lubricant is electrically charged and safe for incidental contact with food; comprising:
selecting the lubricant components from a mineral oil, at least one fatty acid, at least one H1 silicone oil, and a polybutene, each component being acceptable for incidental contact with food;
mixing such mineral oil, at least one fatty acid, at least one H1 silicone oil, and polybutene in at least the following minimum percentages by weight:
Fatty Acid
2.5%
Mineral Oil
50%
Polybutene
3%
H1 Silicone Oil
1%;
applying an electrical charge to one or more portions of a carcass trolley;
applying an opposite electrical charge to the lubricant to form an electrostatically charged lubricant; and
applying the electrostatically charged lubricant to one or more portions of the carcass trolley.
2. The method of claim 1 , wherein applying an opposite electrical charge to the lubricant to form an electrostatically charged lubricant comprises applying an electrical charge to the lubricant in a container.
3. The method of claim 1 , wherein applying an opposite electrical charge to the lubricant to form an electrostatically charged lubricant comprises applying an electrical charge to a sprayer or nozzle capable of electrically charging the lubricant.
4. The method of claim 1 , wherein applying an electrical charge or an opposite electrical charge comprises contact charging, corona charging, inductive charging, and/or ionization.
5. The method of claim 1 , further comprising mixing a rust inhibitor to said mineral oil, at least one fatty acid, at least one H1 silicone oil, and polybutene.
6. The method of claim 1 , wherein at least 65% to 90% by weight of mineral oil is added to said mixture.
7. The method of claim 1 , wherein said at least one fatty acid comprises stearic acid and oleic acid.
8. The method of claim 1 , wherein at least 2.5% to 15% by weight of at least one fatty acid is added to said mixture.
9. The method of claim 1 , further comprising increasing the percentage by weight of said mineral oil, at least one fatty acid, silicone oil, and polybutene to form a lubricant mixture having a viscosity in the range of 20-160 cp.
10. The method of claim 1 , wherein said mixture comprises:
about 85% by weight of mineral oil;
about 8% by weight of at least one fatty acid;
about 2% by weight of at least one H1 silicone oil; and
about 4% by weight of polybutene.
11. The method of claim 1 , further comprising increasing the percentage by weight of said mineral oil, at least one fatty acid, silicone oil, and polybutene to form a lubricant mixture having a viscosity in the range of 20-160 cp.
12. The method of claim 11 , wherein applying an opposite electrical charge to the lubricant to form an electrostatically charged lubricant comprises applying an electrical charge to the lubricant in a container.
13. The method of claim 11 , wherein applying an opposite electrical charge to the lubricant to form an electrostatically charged lubricant comprises applying an electrical charge to a sprayer or nozzle capable of electrically charging the lubricant.
14. The method of claim 11 , wherein applying an electrical charge or an opposite electrical charge comprises contact charging, corona charging, inductive charging, and/or ionization.
15. The method of claim 11 , further comprising mixing a rust inhibitor to said mineral oil, at least one fatty acid, at least one H1 silicone oil, and polybutene.
16. The method of claim 11 , wherein at least 65% to 90% by weight of mineral oil is added to said mixture.
17. The method of claim 11 , wherein said at least one fatty acid comprises stearic acid and oleic acid.
18. The method of claim 11 , wherein at least 2.5% to 15% by weight of at least one fatty acid is added to said mixture.
19. The method of claim 11 , wherein said mixture comprises:
about 85% by weight of mineral oil;
about 8% by weight of at least one fatty acid;
about 2% by weight of at least one H1 silicone oil; and
about 4% by weight of polybutene.
