How is Chocolate Made in Factories?

The process of producing chocolate begins with the grinding of cocoa beans. The nibs are ground in a melangeur to liquefy cocoa butter. This process creates chocolate liquor or chocolate liquid. A second grinding and refining process occurs in a roll refiner or ball mill to remove impurities and reduce particle size while distributing cocoa butter evenly throughout the mass. Eventually, the cocoa mass is ready for consumption.

Milk chocolate

Factory-made milk chocolate is processed with a mixture of sugar, cocoa butter, and milk. The ingredients are blended until they reach the desired taste, texture, and color. Chocolate making machines knead and mix the mixture until it is smooth and creamy. Once the ingredients are combined, they are fed into a chocolate mold or a machine that fills it. It can be stored in an airtight container for several months or as long as one week.

The milk chocolate industry was born when Daniel Peter first developed the formula for milk chocolate. The Greek word gala, which means milk, inspired the name of the chocolate. In 1875, milk chocolate first appeared in the food market. It was wrapped in a copper-trimmed wrapper promoting its health properties and dietary benefits. The wrapper even features a map of Europe. In 1878, the universal exposition in Paris, France, praised milk chocolate. Daniel Peter received a silver medal for his efforts.

Dark chocolate

The ingredients used in dark chocolate manufacturing include sugar, cocoa butter, and a small amount of vanilla. These ingredients are then pressed between heavy steel rollers. The next step, known as “conching,” focuses on increasing the chocolate’s viscosity and smoothness. This process may take hours or even days. Once the chocolate is cooled and thickened, it is poured into molds to harden.

After arriving at the factory, cacao beans are cleaned and sorted. After this step, they are placed in huge drums and roasted for several hours. This step imparts a deep, dark color and intensifies the chocolate’s flavor. The heat from the roasting process loosens the bean’s shell, making it easy to blow off in a winnowing machine. Then, it is packed into wrappers, which are then shipped to retail stores.

Unsweetened chocolate

While unsweetened chocolate is often mistaken for bittersweet, this version is actually made with added sugar and extra fat. While some chocolate manufacturers use soy lecithin, which is GMO-free, others have opted to remove it. Still, some manufacturers prefer PGPR, an artificial emulsifying agent derived from castor oil. This allows manufacturers to reduce the amount of cocoa butter while preserving the same mouthfeel and taste. Chocolate processing also influences texture. Higher-quality chocolates are processed longer than cheaper varieties, which leads to a smoother texture.

Chocolate is a versatile ingredient for baking and cooking, and a variety of flavors can be found in unsweetened varieties. Cacao beans are harvested from different geographical locations around the world and have distinct flavors. Factory-made chocolate can be found in a variety of textures and tastes. While the cocoa butter and sugar in the raw form are identical in quality, they have different chemical compositions. The latter type is known as white chocolate.

Baking chocolate

Most chocolate is produced in factories. However, some chocolate makers still make it at home using traditional methods. In the United States, for example, baking chocolate is made at home using a single ingredient: cocoa bean. This form of chocolate is known as baking chocolate, and is the most pure form. It is made from finely ground cocoa bean and is often called chocolate liquor or Chocolate Mass. It is one of the hardest forms of chocolate.

Once the cocoa butter is extracted, the chocolate paste is mixed with the remaining cocoa butter. This process is important for the texture and flavor of chocolate, and can vary from one type to another. The conching process can take anywhere from a few hours to several days, depending on the type of bean, the desired flavor profile, and the application. Some chocolates are not conched. This is why they are so smooth and delicious.


If you’re a candy bar fanatic, you’ve probably wondered how Hershey’s chocolate is made in a factory. It’s no surprise – it’s the largest chocolate factory in the world! But where are these factories located? The Hershey Company’s Palmyra factory is home to the world’s largest chocolate production line. In fact, this plant makes approximately 70 million Hershey Kisses per day.

The West Hershey expansion is the largest portion of Hershey’s “Project Next Century” initiative to modernize the company’s global supply chain and reduce costs. The company plans to invest at least $50 million to upgrade the facilities in Hershey, Pa., including distribution centers and administrative buildings. The company has eight manufacturing sites in the U.S., including Lancaster, Hazleton, and Stuarts Draft, Va., as well as Ashland, Ore., and Reese’s in Hershey.
