Description

technical field [0001] The invention relates to the technical field of food machinery, in particular to an alloy connector for food machinery and a preparation process thereof. Background technique [0002] Food machinery refers to the mechanical equipment and devices used in the process of processing food raw materials into food. Food machinery can be mainly divided into two categories: food processing machinery and packaging equipment. Food processing machinery includes screening and cleaning machinery, crushing and cutting machinery, Stirring and homogenization machinery, molding machinery, separation machinery, evaporation and concentration machinery, drying machinery, baking machinery, refrigeration machinery, extrusion machinery, conveying machinery, etc. [0003] Alloy connectors are one of the essential parts in food machinery. Therefore, the performance of alloy connectors affects the use and service life of food machinery. However, the poor performance of existing ...
