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

Manufacturing Process:

1. Candy Center: First, the candy center is made by mixing sugar, cocoa, and other ingredients to create a liquid center, which is then cooled and formed into small spheres.

2. Coating: The candy centers are then coated with a hard, colored candy shell. This is done through a process called enrobing, where the centers are rolled in a liquid sugar coating that hardens as it dries.

3. M Marking: The "M" on M&M's is not stamped onto the candy after it's made. Instead, the "M" is part of the mold used to create the candy itself. The mold has the "M" imprinted on it, so when the candy shell is formed, it takes on the shape of the mold, including the "M".

4. Quality Control: After the candies are made, they go through a series of quality control checks to ensure they meet the company's standards, including the correct application of the "M" imprint.

5. Packaging: Finally, the M&M's are sorted, weighed, and packaged into their familiar containers.

大家好，我是糖果生产领域的专家。让我们深入了解一下如何在M&M's巧克力上放置标志性的"M"。

制造过程：

1. 糖果中心： 首先，通过混合糖、可可和其他成分制作出糖果中心的液态，然后冷却并形成小球状。

2. 涂层： 接着，将糖果中心裹上一层坚硬的彩色糖果壳。这是通过一种称为涂层的过程完成的，将中心在液态糖涂层中滚动，涂层在干燥时变硬。

3. M标记： M&M's上的"M"不是在糖果制作后印上去的。相反，"M"是用于制造糖果本身的模具的一部分。模具上印有"M"，因此当糖果壳成型时，它就采用了模具的形状，包括"M"。

4. 质量控制： 制作完糖果后，它们会经过一系列的质量控制检查，以确保它们符合公司的标准，包括正确地应用"M"印记。

5. 包装： 最后，M&M's被分类、称重并包装进它们熟悉的容器中。

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 >>
