Chocolate Production Process

After treatment they were subjected to the cocoa beans in the collection areas, these are sent to different chocolate factories. Upon arrival, the beans are thoroughly examined and classified.

The first thing to realize is the washing and roasting of cocoa beansThen roast is done remove moisture and acidity, while favoring the development of aromas.After cooling, the beans, take a husking and sieving machine, which opens the roasted beans and separates the skins, light, of the edible part.

The shells and skins are recycled as compost for gardens, or to make low-quality fats commercially called Cocoa.

The Cocoa has a relatively perfume and taste similar to chocolate powder, but it lacks the original characteristics of the chocolate made from cocoa. Is largely done so industrialized and is dark brown.

Then grind the cacao beans. Mashed beans go through a battery of mills and subjected to a shake at a constant temperature of 60-80 °, the duration of this treatment can range from 18 to 72 hours.

The duration influences the texture of the resulting chocolate: a less beaten more harshly. As a result of crushing, the cellular tissue of beans, containing 50 to 60% of cocoa butter, allowing the release of this fat, which is then liquefied by heat generated by friction.

The result is a smooth but thick paste, cocoa paste: a suspension of substances with cocoa cocoa butter.For use in different products, this paste is homogenized and heated to 100 º, later to be propelled in hydraulic presses. Is extracted and the maximum amount of cocoa butter, which is filtered and packed into large blocks.

The cocoa paste, with a reduced fat percentage between 8 and 22%, is in the form of bread or loaf. The solid part is tough, it solidifies to 600 atmospheres.The characteristic crack and the delicate glow of good chocolate is due to the crystalline structure of cocoa butter.

The final flavor of chocolate depends on the selection and mixing of different types of cocoa beans. These types of cocoa beans can be divided between strong and soft varieties, which are usually mixed in proportion.The preparation of the chocolate goes through its final phase with a careful blend of pasta and cocoa butter with sugar, refining the resulting composition through crushers, refiners that produce a very thin pasta.

The shell is an additional kneading troughs that originally were shaped shell. The paste is beaten and stretched into the trough of rollers, with a slow rocking motion, over a period of time and a temperature that varies depending on the product to be obtained. All these operations are performed at a temperature above the melting point of cocoa butter, therefore, remains liquid.

The last step is the tempering, which is completely melted chocolate to 50 ° C to rupture the crystal structures of cocoa butter, cool to 30 º to restore the structure, and ultimately, increase temperature slightly for crystals are grouped into smaller again.Typically, the chocolate has added vanilla (or some derivative such as vanillin) as flavoring, and soy lecithin as an emulsifier and stabilizer to improve the texture and keeping qualities of chocolate, in total, both products do not exceed 1% of chocolate.

Production Process, Injection Molding

Injection molding is a process that involves injecting semi polymer or ceramic in the molten state (or rubberized) in a closed mold under pressure and cold, through a small hole called a gate. In that mold material solidifies, beginning to crystallize in semicrystalline polymers.

The final piece or part is obtained by opening the mold and remove from the casting cavity.

Polymers have succeeded in substituting other materials such as wood, metals, natural fibers, ceramics and even precious stones injection molding is a more environmentally friendly process compared to paper manufacturing, logging or chrome. It does not pollute the environment directly, does not emit gases or aqueous wastes with low levels of noise. However, not all plastics can be recycled and some that can be recycled are deposited in the environment, causing environmental damage.

The popularity of this method is explained with the versatility of parts that can be made, speed of manufacture, design scalable from rapid prototyping processes, high levels of production and low costs, high or low based on cost automation of the part geometries very difficult that would be impossible by other techniques, castings require little or no finish as they are finished with the desired surface roughness, color and transparency or opacity, good dimensional tolerances of castings with or without inserts and with different colors.
