MAJA ESM Derinding and Defatting Skinners

Comfortable operation for better skinning performance

  • Combined derinding and defatting solution
  • Optimized process
  • Product-specific work tables
  • Ideal ergonomics at work


The MAJA ESM 5550 is designed for open-top derinding of round-shaped pork cuts, e.g. ham and shoulder, with and without bones.

With its extra-wide cutting width, the MAJA ESM 5800 is the appropriate solution for processing large pork loins.

To allow the simultaneous removal of rind and fat, the MAJA ESM 5550/1 is equipped with a twin knife holder, so that boneless cuts can be derinded and defatted in any thickness in one step. The removed rind and fat leave the machine separately and do not need to be sorted, which saves labor.


  • Operator-friendly machine structure with ergonomic machine design for maximum operator efficiency and productivity
  • Specially designed work tables facilitate the handling of each type of cut
  • Geometry of the defatting knife holder allows power-saving defatting, even with big and heavy meat cuts.
  • Flexible machine positioning in different deboning lines
  • Height-adjustable outlet table
  • Ergonomic, flat foot pedal design (flat material), thus more comfort for the operator
  • Tool-free changeover of the machine to another type of cut: The work tables, work table support and the MAJA ESM 5550/1 's defatting knife holder can be quickly exchanged without tools and dismounted for cleaning.
  • No removal for cleaning and changing of the derinding knife holder: It remains in the machine and is only put into cleaning position. Advantage: This sensitive key part of the machine cannot be damaged by accident. Thus, the derinding quality is always good,maintenance costs are reduced and operational safety is increased.
  • Fast and easy changing and adjustment of the derinding knife, tool-free with quick-locking device
