Definitions

  • the present invention relates to a lubricant concentrate, of which the aqueous use solution is suitable for lubricating, cleaning and disinfecting of conveyor belt installations in the food industry, particularly by means of immersion or automatic belt lubricating systems.
  • the invention further relates to a process for the production of the lubricant concentrate or the aqueous use solution of the lubricant concentrate as well as the use of the lubricant concentrate and the aqueous use solution for lubricating, cleaning and disinfecting of conveyer belt installations, in particular by means of immersion lubricating or automatic belt lubricating installations, particularly in the food industry.
  • the use thereby particularly relates to the filling up with foods, especially with beverages, of glass and plastic bottles, boxes, glasses, vessels, beverage containers, paper and cardboard holders and the like.
  • the object of the invention is a process for the conveyance of beverage packings made of metal, glass, paper, cardboard and/or plastic, particularly in this case polyethylene terephthalate or polycarbonate, whereby the lubricant concentrate according to the invention, respectively its aqueous use solution, is applied.
  • the applied chain lubricants can in principle be divided into three main groups :
  • a process is disclosed in DI for the maintenance of chain shaped bottle conveyors in beverage filling works, especially in breweries, in which the chain shaped bottle conveyors are lubricated with conveyor lubricants on basis of neutralized primary fatty amines and are cleaned with cationic cleaning agents or organic acids.
  • conveyor lubricants on basis of neutralized primary fatty amines are used, which preferably show 12 to 18 C-atoms and have an unsaturated content of more than 10%.
  • aqueous lubricant solution which solution consists of (A) 0.001 to 1 wt . % on basis of the weight of the aqueous lubricant solution of at least one compound with the formula
  • R is a saturated or an unsaturated, branched or linear alkyl group with 8 to 22 carbon atoms
  • R is hydrogen, an alkyl group or hydroxyl -alkyl group with
  • A is a linear or branched alkyl group with 1 to 8 carbon atoms and A is a linear or branched alkylene group with 2 to 4 carbon atoms, which has a pH-value of 5 to 8, for the lubrication of conveyor belts .
  • Both the lubricants known from DI and D2 generally have a poor water hardness tolerance. I.e. they tend to react with compounds in the water, particularly with sulphates, bicarbonates, phosphates and carbonates, especially in alkaline water, as well as with other compounds which are present in the water, whereby the reaction products could lead to the development of waste, which block the dosing installation. This leads to the feared "nozzle-blocking" of sieves and spray nozzles of the dosing installation.
  • the lubricants on basis of fatty amines also have un unsatisfactory foam behaviour.
  • the lubricants according to D2 tend to have an intensive foam formation, which requires afterwards a cleaning of the goods conveyed on the conveyor belt.
  • Other lubricants like e.g. the composition known from DI , rather tend to a too low formation of foam, which leads to a too fast disappearing of the applied lubricating layer.
  • the lubricant systems known from D3 further exhibit the same disadvantages, which are mentioned above with respect to the lubricants known from D2.
