Introduction and Cultural Context

  • Chocolate coins = symbolic edible money in various cultures
  • Christmas stockings: stuffed with chocolate coins celebrating Saint Nicholas charity
  • Hanukkah: given to Jewish children to teach money value
  • No purchasing power but generate appreciative smiles from kids

Raw Material Preparation

  • Process starts with giant chocolate bars
  • Workers transfer bars to kettle (double boiler system)
  • Hot water bubbles/steams inside sleeve shell to melt chocolate
  • Kettle contains 2.5 tons liquid chocolate

Tempering Process

  • Machine pumps chocolate through long pipe with cooling zones
  • Chocolate thickens but doesn't solidify
  • Tempering creates precise crystal structure for proper texture/taste

Sheet Formation

  • Thick liquid chocolate flows onto conveyor
  • Broad blade levels chocolate to specific thickness
  • Creates long, evenly spread chocolate sheet
  • Chocolate begins coagulating/hardening

Cooling Process

  • Travels through refrigeration tunnel ~15 yards long
  • Journey transforms liquid chocolate to solid state

Die Cutting Operation

  • Clean/prepare spring-loaded die (cookie cutter style)
  • Punches out round blanks
  • Key difference: cutters are long/tubular
  • Blanks stack up as they're punched out
  • Lattice work leftovers re-melted back into process
  • Zero chocolate waste

Magazine Collection

  • Dozens of coin blanks stack in each magazine
  • Leftover chocolate accumulates in bin
  • Transferred back to melting pot for reuse

Wrapping and Embossing

  • Wrap chocolate first, then emboss wrap + blank simultaneously
  • Glossy gold foil sheets travel between rollers for even tension
  • Forked arm moves 2 chocolate blanks between foil sheets
  • Piston-like knives wrap, cut, fold foil around blanks
  • Forked arm delivers foil-wrapped blanks to die press

Die Press Operation

  • Stamps designs on both sides of coins
  • Makes impression on foil through to chocolate
  • Chocolate still warm enough to receive image
  • Die heads used for embossing (example: American penny markings)
  • Foil discards collected in bin for recycling

Production Capacity

  • 150,000 foil-wrapped coins per day
  • Change currency type by switching die heads
  • Multiple sizes with range of different illustrations available

Final Processing

  • Coins spill onto conveyor to collection bin
  • Packaging in traditional mesh bags
  • Start to finish: <1 hour per chocolate coin
  • Product varieties: gold dollars, $5 poker chips

Factory Output

  • Daily jackpot of chocolate money production
  • Never shortage of edible cash
  • Product decision options: poker chip vs chocolate penny
