Chocolate is one of the most popular foods in the world. Its raw materials are mainly cocoa butter and cocoa powder. After the cocoa beans are fermented, roasted, and peeled, they are ground and pressed into cocoa liquor. Cocoa liquor can be separated into cocoa butter and cocoa powder, and then further processed into other types of chocolate food. With the increasing demand for chocolate in the market, the establishment of a complete chocolate production line is an indispensable step for chocolate manufacturers.
The production process of chocolate
Chocolate production mainly includes the steps of mixing, grinding, refining, tempering, casting, and forming.
- Raw material mixing: The process of uniformly mixing sugar, milk powder, cocoa mass, cocoa butter, and other auxiliary materials.
- Grinding: It is the process of grinding the uniformly mixed raw and auxiliary materials. This process can be divided into two steps according to the particle size of the obtained raw and auxiliary materials: coarse grinding and fine grinding.
- Refining: The main purpose is to remove the volatile acid, moisture, and peculiar smell of the slurry, and at the same time produce a burnt smell, highlighting the chocolate flavor.
- Tempering: The purpose of temperature adjustment is to make the cocoa butter crystals in the slurry form stable crystals and express them with a black luster. And it also aim to extend the shelf life of the product. (Temperature adjustment is the key process)
- Molding: Molding is to make the passing chocolate into various shapes. Liquid chocolate material is poured into a quantitative model plate during this process. When the material temperature drops below the melting point of cocoa butter, the stroked crystal forms are arranged according to strict crystallization laws, forming a dense texture state, resulting in obvious volume shrinks, and finally forms a variety of colorful and beautiful chocolate products.
Main components of the chocolate making machines
The chocolate production line is mainly composed of the cocoa melter, Chocolate conche, temperature holding tank, continuous tempering machine, and the final chocolate forming machine. Auxiliary equipment can also be equipped with the powder sugar machine, the decorating machine, chocolate coating pan, chocolate delivery pump, etc.
