Peanut butter production: from nut to treat
Peanut butter is a delicious and nutritious treat that is loved by many people around the world. It is widely used in cooking, including sandwiches, pastries, sauces, and even in some traditional dishes from different cultures. But how is this delicious pasta made? Let's take a look at the peanut butter production process.
The process begins with the selection of high-quality raw materials - peanuts. They can be used as whole nuts, or pre-roasted and peeled. The shelled nuts are dried to remove excess moisture and increase their shelf life.
The next step is roasting the nuts. Nuts are placed in special ovens where they are roasted at a certain temperature and time. Roasting gives the nuts a deep aroma and enhances their flavor.
After roasting, the nuts cool down and then go through a cleaning process. They undergo mechanical removal of husks and other undesirable impurities in order to obtain pure peanut grain.
The shelled nuts are sent to a colloid mill, where the nuts are ground to a thick cream. As the nuts are processed, they release oil, which helps to achieve a smooth paste texture.
Depending on preference and recipe, additional ingredients may be added during the production of peanut butter. It can be salt, sugar, honey, vegetable oil, or other natural additives to add flavor and texture to the paste.
The finished nut butter can be packaged in glass jars, plastic containers or tubes. Hermetic packaging guarantees the preservation of freshness and quality of the product.
Working principle of colloid mill
The principle of operation of a colloid mill is based on the process of colloidal grinding, which makes it possible to obtain very fine particles of a substance and create colloidal dispersions. The colloid mill consists of two main components - the stator and the rotor.
The process of operation of a colloid mill begins with the receipt of raw materials, which are fed into the zone between the stator and the rotor. When the rotor rotates, intensive mixing and grinding of raw materials takes place. The rotor rotates at high speed, which creates shear and compression forces that allow the particles of raw materials to be distributed along the channels or grooves of the stator.
As a result of this process, the raw material is subjected to intense friction and shear forces, which leads to the destruction of the particles and obtaining very small sizes. The shape and dimensions of the channels or slots in the stator determine the final texture and consistency of the resulting product.
One of the key advantages of the colloid mill is the ability to obtain stable colloidal dispersions without the need for additional stabilisers or emulsifiers. This is done through intensive mixing and grinding of the raw materials, which allows you to create a stable mixture of water-oil or oil-water.
Colloidal mills are widely used in the food industry for the production of various products, such as peanut butter, chocolate, sauces, oils, mayonnaise, ketchup and other products. Also widely used in the cosmetic, pharmaceutical and chemical industries.
