Hello, I'm an expert in the field of manufacturing and confectionery production. Let's dive into the process of how the "M" is put on M&M's.

When M&M's are produced, the process involves several steps. Here's a simplified overview:


1. Preparation of Ingredients: The ingredients like sugar, cocoa, fat, and other components are mixed and heated to create a liquid chocolate mixture.


2. Molding: The liquid chocolate is cooled and then molded into small round shapes. This is typically done using a process called enrobing, where the center is coated with a thin layer of chocolate.


3. Coating: After the initial chocolate layer sets, the candy is coated with a colored candy shell. This shell is made from a mixture that includes sugar, corn syrup, and other ingredients.


4. Stamping: The "M" is applied to the candy during the coating process. The candies are still on a conveyor belt, and they pass through a machine that has a series of engraved stamps or rollers. As the candies move along, these stamps press the "M" onto the soft candy shell.


5. Curing: Once the "M" is stamped, the candies are allowed to cure. This means they are left to set and harden at a controlled temperature.


6. Quality Control and Packaging: Finally, the candies are inspected for quality, and then they are packaged and ready for distribution.

Blank M&M's sit on a special conveyor belt that has a dimple for each candy to sit in, and roll through a machine where vegetable dye is transferred from a press to a rubber etch roller that gently prints the M on each piece. The printer can stamp some 2.5 million M&M's an hour.read more >>
