In industrial mango processing (puree, pulp, canned slices, mango leather/amchur):

• Pulper machines extract smooth pulp by separating peel and fibrous seed stones.
• Retort machines provide pressurized thermal sterilization for canned mango products.
• Dryer machines (tray dryers, spray dryers) produce dehydrated mango flakes, powder, and fruit bars.
• 'Roser Machine' is not an equipment used in food/mango processing.
  
  Option analysis:
• Pulper Machine: Indispensable core equipment for mango pulp extraction.
• Retort Machine: Essential canning autoclave for microbiological shelf stability.
• Roser Machine: Correct answer, non-existent or irrelevant equipment in mango processing.
• Dryer Machine: Standard unit operation for dehydrated mango products.
