Abstract

Lubricant concentrate for conveyors containing at least one alcohol component not containing nitrogen, selected from monohydroxy, dihydroxy and trihydroxy compounds as well as their esters and ethers, and in addition at least one further component selected from a) nitrogen-containing, organic, preferably aliphatic compounds with fewer than 14 C atoms in the molecule and fewer than 8 C atoms in the molecule directly joined to one another, and/or b) an organic acid with 1 to 18, preferably 1 to 10 C atoms in the molecule.

Claims (39)

1. A foodstuff conveyor lubricant concentrate composition comprising:

a. at least about 50 wt. % glycerol;

b. at least one nitrogen compound having the formula

wherein R 1 , R 2 , and R 3 are selected from the group consisting of H and (CH 2 ) n —OH where n may be 1 or 2 and wherein not all of R 1 , R 2 , and R 3 are H; and

c. at least one organic acid having from 1 to 10 carbon atoms;

wherein the composition is free of an alkylpolyglycoside or a fatty acid in the form of a water soluble alkali metal or alkanolamine salt.

2. The composition of claim 1 , wherein the nitrogen compound is present from about 0.1 wt. % to about 20 wt. %.

3. The composition of claim 1 , wherein the organic acid is present from about 0.1 wt. % to about 20 wt. %.

4. The composition of claim 1 , wherein the nitrogen compound is selected from the group consisting of monoethanolamine, triethanolamine, and mixtures thereof.

5. The composition of claim 1 , wherein the organic acid is selected from the group consisting of acetic acid, caproic acid, and mixtures thereof.

6. The composition of claim 1 , wherein the composition is a liquid, a gel, an emulsion, a paste, or a dispersion.

7. The composition of claim 1 , further comprising an antimicrobial agent.

8. The composition of claim 7 , wherein the antimicrobial agent is selected from the group consisting of alcohols, aldehydes, antimicrobial acids, carboxylic acid esters, acid amides, phenols, phenol derivatives, diphenyls, diphenylalkanes, urea derivatives, oxygen-nitrogen acetals, oxygen-nitrogen formals, benzamidines, isothiazolines, phthalimide derivatives, pyridine derivatives, antimicrobial surfactants, guanidines, antimicrobial amphoteric compounds, quinolines, 1,2-dibromo-2,4-dicyanobutane, iodo-2-propynlbutyl carbamate, iodine, iodophores, peroxides, peracids, and mixtures thereof.

9. The composition of claim 1 , wherein the composition is diluted with water to form a dilute solution.

10. The composition of claim 9 , wherein the dilution factor is below 10,000.

11. The composition of claim 10 , wherein the dilution factor is from 0 to 10.

12. A method of lubricating a conveyor for conveying beverage containers comprising:

a. providing a lubricant concentrate comprising:

i. at least about 50 wt. % glycerol;

ii. at least one nitrogen compound having the formula

wherein R 1 , R 2 , and R 3 are selected from the group consisting of H and (CH 2 ) n —OH where n may be 1 or 2 and wherein not all of R 1 , R 2 , and R 3 are H; and

iii. at least one organic acid having from 1 to 10 carbon atoms;

wherein the concentrate is free of an alkylpolyglycoside or fatty acid the form of a water soluble alkali metal or alkanolamine salt;

b. diluting the concentrate to form a dilute solution; and

c. applying the dilute solution to the conveyor.

13. The method of claim 12 , wherein the nitrogen compound is present from about 0.1 wt. % to about 20 wt. %.

14. The method of claim 12 , wherein the organic acid is present from about 0.1 wt. % to about 20 wt. %.

15. The method of claim 12 , wherein the nitrogen compound is selected from the group consisting of monoethanolamine, triethanolamine, and mixtures thereof.

16. The method of claim 12 , wherein the organic acid is selected from the group consisting of acetic acid, caproic acid, and mixtures thereof.

17. The method of claim 12 , wherein the lubricant concentrate is a liquid, a gel, an emulsion, a paste, or a dispersion.

18. The method of claim 12 , further comprising an antimicrobial agent.

19. The method of claim 18 , wherein the antimicrobial agent is selected from the group consisting of alcohols, aldehydes, antimicrobial acids, carboxylic acid esters, acid amides, phenols, phenol derivatives, diphenyls, diphenylalkanes, urea derivatives, oxygen-nitrogen acetals, oxygen-nitrogen formals, benzamidines, isothiazolines, phthalimide derivatives, pyridine derivatives, antimicrobial surfactants, guanidines, antimicrobial amphoteric compounds, quinolines, 1,2-dibromo-2,4-dicyanobutane, iodo-2-propynlbutyl carbamate, iodine, iodophores, peroxides, peracids, and mixtures thereof.

20. The method of claim 12 , wherein the concentrate is diluted to a dilution factor below 10,000.

21. The method of claim 20 , wherein the dilution factor is from 0 to 10.

22. The method of claim 12 , wherein the dilute solution is applied to the beverage containers.

23. The method of claim 12 , wherein the applying step is controlled using a computer.

24. The method of claim 12 , wherein the lubricant concentrate is diluted using water.

25. The method of claim 12 , further comprising the step of cleaning the conveyor with a cleaning agent.

26. The method of claim 12 , wherein the dilute solution is applied using a nozzle.
