Butter- its production, types, and uses

 Butter is made from the fat in milk by Butter Production Lines. It is a highly caloric product due to its high-fat content, which also provides significant vitamins A and D.

Butter is a widely consumed food that shows great versatility in the kitchen.

The butter is the product obtained from milk by mechanical means or by whipping cream pasteurized. The term butter designates only the product made with milk or cream from cow's milk.

How is butter made?

Butter production consists of several stages:     

1st. The cream is separated from the milk (skimming). It can be done either by leaving the milk at rest for several hours or skimming machines designed for this purpose.

2nd. Then the cream will be transformed into Butter Silos through a series of operations. They include pasteurization of the cream, deodorizing it, eliminating compounds, subsequent refrigeration, and maturation.

3rd. The maturation of the cream is the last step in preparing cream and butter to make it one of the key processes. At this stage, the cream had no aroma after the processes to which it had been subjected and is inoculated with lactic acid bacteria. In industries, Butter Making Machines are in use extremely.

Types of butter

Different types of butter receive their name based on several criteria:

By its origin

Butter is called the product as such obtained from cow's milk or cream. Butter can be obtained from the milk of other animal species such as sheep, goat or buffalo. In this case, its name must refer to the species from which it comes. Sheep or goat butter has a lighter color and a higher fat content than that of the cow.

By the manufacturing process

a) Sweet cream butter is produced from fresh cream matured without acidification. The sour cream butter is obtained from cream that has been matured with acidification.

b) Whipped butter, into which air is blown during its production process, reaching a content of 30 percent air. This facilitates its smoothness or ability to spread, being a lighter butter, which melts better than ordinary butter. Butter Packing Machines pack this type of butter.

By its composition

a) Light or low-calorie butter with a lower fat content than usual, with values between 41 and 65 g / 100 g.

b) Butter with non-dairy ingredients added, for example, garlic, aromatic herbs, etc.

c) Butter with salt or salted butter, to which sodium chloride (common salt) is added in its preparation.

Use in kitchen

Butter is a widely consumed food in many countries. Its ease of melting and spreading, as well as its delicate flavor and aroma, facilitate and extend its culinary uses. From the traditional bread and butter toast for breakfast to the sauces seasoned with aromatic herbs that accompany dishes with the most varied ingredients, butter shows great versatility.

It is widely used in confectionery, one of the most used ingredients in the preparation of cakes, pastries, etc. However, butter is not suitable for cooking at high temperatures.

Helpful tips

It is necessary to take care of conservation's ideal conditions to preserve its sensory qualities and nutritional value. Due to its fatty nature, butter can easily spoil if the storage conditions are not adequate. The main alterations are those caused by rancidity and oxidation of fat.

Know a little about butter production line and centrifuges

 Dr. Fritz invented the continuous butter making the machine in 1941. Many companies have developed and innovated this principle. In the beginning, it was only possible to process small amounts of cream to produce butter. The subsequent generations of machinery, up to the current BUE type, are designed for large-scale industrial production. The company process lines are designed as a complete solution. In addition to the butter machine, including all the components necessary to produce high-quality butter. They include from the tanks to the pasteurization unit, with all the control elements and the pipes. This means fewer interfaces. The industries use Bottle Loaders to load the butter products when they need to deliver it to a far place.

The production base: the butter machine

The manufacture of butter, that is, the transformation of cream into butter, is carried out by reversing the oil-in-water emulsion into a water-in-oil emulsion. To achieve this phase inversion, it is necessary to mechanically break down the fat globules by incorporating air using Churns.

The fat globules are surrounded by a membrane made up of phospholipids, proteins, enzymes, water, and copper and iron ions. These elements prevent the fat from melting in raw milk.

By destroying this membrane using Bottle Unloaders, fat is released, made up of liquid and crystalline fractions. The liquid fractions combine to form fatty agglomerates, which are the butter granules. These granules, in turn, float on top of the aqueous phase, the buttermilk. These are separated and cooled by the machine and used as a valuable by-product.

The ideal process for butter

Industrial process lines can be utilized to make sweet or sour butter, ready from sweet or sour salve. Integrating additional ingredients also enables mass production of low-fat mixed fats, adding fat vegetable additives, and even low-solids non-fat (SNF) additives. More and more consumers are on a low-fat diet, so these modified mixed fats' commercial importance will continue to grow.

Many production companies' process lines, both traditional and modified, allow all types to be manufactured with high quality. The complete solution can incorporate a CIP (clean in place) system to clean the system easily and reliably. This CIP system includes a hot water tank and Crate Washers, a tank for the special caustic solution and the valves, and the necessary heating system with their corresponding pumps.

What is a centrifuge?

A centrifuge is a machine that rotates a sample to separate its components or phases by centrifugal force, based on their density.

There are several types of Centrifuges, commonly for specific purposes.

A typical application is to accelerate the sedimentation process using Churns, dividing the plasma, and serum in the laboratory analysis process.

It is also used to determine the blood group by taking a capillary sample. In this case, the machine used is called a microcentrifuge.

It is widely used in quality control laboratories in factories that make citrus-based juices. They are used to control the level of the fine pulp of these, separating the fine pulp from the squeezed juice.

Another application of Centrifuges is the elaboration of olive oil. In it, the olives once ground and beaten, are introduced into a horizontal centrifuge. In this, the oil, which is the least heavy fraction from the rest of the olive components, are separated; water, bone, pulp, etc.
