The first step in making chocolate is to roast cacao nibs, the raw ingredients. While the exact cooking time and temperature varies among manufacturers, the longer the nibs are roasted, the less cacao will be present in the finished product. Dark chocolate, for example, is roasted for a shorter time than milk chocolate. The nibs are then ground into a liquid chocolate that tastes bitter. Here’s how each step works:
Conching machine
A typical conching machine consists of a large jacketed vessel in which chocolate ingredients are tumbling. This tumbling process is a heat-generating process and can also create uneven mixing. When a large batch is processed, a heating process is required after conching. Fortunately, the time and effort involved in this process is minimal. Moreover, it requires only a small one-off investment. After all, the end result is chocolate that is rich in antioxidants, fats, and fiber.
During the chocolate production process, the conching machine breaks down the material particles and improves the flavor and texture. It also makes chocolate bars more palatable by reducing water content. In chocolate production, the quality of a bar depends on how the chocolate is conched. The more time a chocolate bar is conched, the more expensive and desirable it will be. In many cases, chocolate manufacturers install a conching machine in their factories to improve the chocolate’s taste.
Soy lecithin additive
Soy lecithin is a common additive used by chocolate manufacturers. It is actually a by-product of soy oil refining. Refining companies sell this waste to the food industry. It is neither organic nor GMO. However, some consumers do not like the taste of chocolate. Regardless of your stance on soy, you should know that soy lecithin is generally safe to eat.
Soy lecithin was first used as an additive in margarine in the mid-1920s. This was at the same time as research on therapeutic uses and industrial applications. At the time, most of this research was in Germany, but it was also done to obtain patents. In fact, the first soy lecithin patent was granted in Germany to Hermann Bollmann and Hansa Muehle. Both men were credited with developing the ingredient.
Soy lecithin is an important ingredient in the making of chocolate. It helps the chocolate to flow smoothly through a machine. Although it is not as expensive as cocoa butter, it can be a beneficial addition. Soy lecithin can be particularly helpful for chocolate manufacturers with large setups. Soy lecithin reduces the viscosity of chocolate, which makes it easier to handle and temper. It is also known to have natural antioxidants.
Refiner machine
Refiner machines in chocolate factories use raw materials like cocoa or sugar to produce the finished product. They must be convex to compensate for cylinder flexion and extension, ensuring uniform refining. The blades of the machine detach the chocolate film from its surface. The first refiner machines generally had three rollers and mass had to be processed two or three times. Now, five-roller refiners are available.
Refiner machines usually include two main parts: a buffer and a mixer. The buffer is located above the pre-refiner. The two rollers are fed by a fully automated slide gate. The rolls are driven by one frequency-controlled drive or two, which gives them more flexibility in speed differentials. Once the process is complete, the refined chocolate mass is transported to the next step. Conveyors are usually used to move the finished product.
Baking chocolate
Chocolate is a popular snack in the United States, where it is widely available. Chocolate factories use a process called chocolate enrobing. The process involves re-liquefying the chocolate powder in conches. Then, the chocolate is sent through a freezing chamber for about two hours to harden the chocolate. After the conch, the chocolate is poured into a wrapper and shipped to retail stores.
A factory-made chocolate bar contains at least 45% cocoa butter, and it has a distinct aroma. In addition, most manufacturers use non-fat milk, sugar, and other ingredients. The cocoa butter content in most products is 10 to 22 percent. To make chocolate even more palatable, the process uses alkali, which makes the chocolate appear darker and less bitter. However, this process is not ideal for all chocolate, as the result is a product with a slightly different taste.
