Problems solved by technology

[0011] A disadvantage of the known food-compatible lubricants used in the high-temperature area is that they generally have unsatisfactory, technical properties
Thus, the food-compatible lubricants used hitherto have good oxidation resistance and acceptable pour points, but their residue properties after complete evaporation do not meet the high requirements required in high-temperature applications

[0079] Preparation of the high temperature oil according to the invention for the food industry

[0080] The two trimellitates are preset in a stirred boiler. At 100° C., polyisobutene and optionally another oil are added thereto under stirring. Subsequently, the mixture was stirred for 1 h in order to obtain a homogeneous mixture. The antiwear additive and antioxidant were added to the boiler at 60°C with stirring. After about 1 hour, the finished oil can be filled into the provided containers.

[0081] Composition of high temperature oil:

[0082] Table 1 shows the composition of the high temperature oil and the resolubility of the oil residue after complete evaporation of the oil as a function of the added amount of polyisobutene.

Abstract

The invention relates to a food-grade high-temperature lubricant, in particular a high-temperature oil or a high-temperature grease comprising the following components: a) at least one oil selected from a trimellitic acid ester or a mixture of various trimellitic acid esters, alkyl aromates, preferably an aliphatically substituted naphthalene or estolidene; b) a hydrogenated or fully hydrogenated polyisobutylene or a mixture or hydrogenated or fully hydrogenated polyisobutylene; and c) additives, individually or in combination with each other. In the case of the high-temperature grease, a thickening agent is added.

Description

technical field [0001] The present invention relates to high-temperature lubricants, especially high-temperature oils, based on aromatic esters, such as one trimellitate and mixtures of different trimellitates, heteroaromatics, long-chain esters (Estoliden) and fully hydrogenated or hydrogenated Polyisobutylene or mixtures thereof. Furthermore, the high temperature lubricant may be a high temperature grease, when 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 products. Background technique [0002] In addition to the lubricating effect, the lubricants must also fulfill a number of further tasks: they must cool, reduce friction, wear and force transmission, protect against corrosion and at the same time have a sealing effect. [0003] Conventional lubricants are not suitable for high-temperature applications, since they are d...
