Definitions

  • the invention relates to a high-temperature lubricant, in particular a high-temperature oil based on estolides and a fully hydrogenated or hydrogenated polyisobutylene or a mixture thereof. Furthermore, the high-temperature lubricant can be a high-temperature grease if a thickener is also added to the above-mentioned components. The invention also relates to the use of these high temperature lubricants for lubricating work equipment used in the processing of food.
  • the lubricants have to fulfill a number of other tasks: They have to cool, reduce friction, wear and power transmission, protect against corrosion and at the same time have a sealing effect.
  • lubricants are not suitable for high-temperature applications because they are destroyed at high temperatures, for example via oxidation and / or thermal decomposition reactions and polymerizations, and their lubricating properties are severely restricted.
  • the lubricant becomes volatile in low molecular weight Components split. Their evaporation leads to undesirable changes in viscosity, loss of oil and excessive vapor formation. This results in a loss of the lubricating effect.
  • the lubricants also lose their lubricating effect through polymerization due to the formation of insoluble polymerization products.
  • Synthetic esters are often used as base oils for high-temperature applications because they have very good oxidative, hydrolytic and thermal stability.
  • the lubricants In order to meet the diverse requirements of high-temperature applications, the lubricants must have, among other things, high stability, low coefficients of friction and high wear resistance. In order to be able to guarantee uniform lubrication even at high temperatures, a liquid lubricating film must remain between metal parts during the entire processing process. For this reason, the lubricant must only evaporate a little at the maximum processing temperature, form few residues and form as few cracking residues as possible.
  • High processing temperatures often occur in food processing, such as cooking, baking, simmering, roasting, braising, sterilizing, roasting and steaming.
  • Various tools are used in these processes.
  • High temperature-resistant lubricants are required to lubricate these tools.
  • a food grade lubricant H1 should be suitable if the lubricant can come into direct or indirect contact with food, beverages and food.

Lubricants that are non-toxic and non-carcinogenic can achieve an "H2" classification. However, when using "H2" lubricants, any contact with the food must be ruled out.
  • the disadvantage of the known food-grade lubricants that are used in the high-temperature range is that they often have an unsatisfactory technical performance.
  • the resulting cracking residues form deposits that have to be removed after a while.
  • the operation of the system must be stopped and the residue removed or the components replaced.
