Definitions

  • the invention relates to a high-temperature lubricant, more particularly a high-temperature oil based on an aromatic ester, such as a trimellitic ester and mixtures of different trimellitic esters, heteroaromatics, estolides, and a fully hydrogenated or hydrogenated polyisobutylene or a mixture thereof.
  • the high-temperature lubricant may, furthermore, be a high-temperature grease, if a thickener is added to the components stated above.
  • the invention further relates to the use of these high-temperature lubricants for lubricating equipment used in the processing of foods.
  • the lubricants are required to fulfill a great many other functions: they must cool, reduce friction, wear, and force transmission, protect against corrosion, and at the same exhibit a sealing effect.
  • Base oils used for high-temperature applications are often synthetic esters, since these esters possess very good oxidative, hydrolytic, and thermal stability.
  • the lubricants are required to exhibit qualities including high stability, low coefficients of friction, and high wear resistances.
  • the lubricant In order to be able to ensure uniform lubrication even at high temperatures, there must be a liquid lubricating film maintained between metal parts throughout the processing operation. At the maximum processing temperature, therefore, the lubricant must undergo little evaporation, form little residue, and form cracking residues to as small an extent as possible.
  • the base oils for lubricating equipment for the processing of foods are subject to particular requirements in relation to their environmental compatibility and toxicity. Fundamentally, a food-grade lubricant ought to have H1 suitability if the lubricant can come into contact, directly or indirectly, with foods, beverages, and comestibles.
  • the preferred areas of application in the food industry include chains in baking ovens, and other high-temperature applications, and also ancillary transport means, more particularly trolleys and their bearings.
  • H1 The grading “H1” is to be met by lubricants which are in “incidental food contact”, meaning that they are in occasional, technically unavoidable contact with foods. Intended or lasting contact, however, must be ruled out even in the case where “H1” lubricants are used.
  • An “H2” classification can be achieved by lubricants which are not toxic and not carcinogenic. With the use of “H2” lubricants, nevertheless, any contact with the food must be ruled out.
  • a disadvantage of the known food-grade lubricants which are used in the high-temperature sector is that they often lack satisfactory technical performance.
  • the food-grade lubricants used to date do possess good oxidation resistance and an acceptable pour point, their residue behavior after full evaporation does not conform to the exacting requirements required in high-temperature applications.
