History of Juicer

Screw Juicers

At present it is difficult to find a house where there would not be a juicer in the number of household appliances. This simple device allows you to get fresh juice from berries, fruits, vegetables. Such a drink contains useful substances, a significant part of which are deprived of juices sold in packages or in any other container. History of Juicer

To get the juice knew how to go back to antiquity. The process was not complicated, although everything was done in several stages. In the beginning, if it was a question of large fruits, they were cut into small parts. Then an ordinary press was used. This made it possible to obtain a mass similar to mashed potatoes. If necessary, it could be filtered or strained through a sieve.


As time went. Technologies have improved. This also affected the process of obtaining juice. Instead of the usual press began to be used screw. In the device equipped with a screw, the fruits were crushed by cutting against the wall of the body, then these particles moved forward through the rotation of the screw. The screw itself had a conical shape, which provided an increase in pressure on the crushed parts of the fruit. They continued to decrease in size, and at the final stage, where the top of the cone was, the resulting mass was filtered through an existing grid. However, in this case, a significant amount of juice was present in its residues.

The next step was the use of a centrifuge to produce juice. After several such attempts, in the middle of the twentieth century, juicers with centrifuges began to make companies in several countries at once. Initially, such devices were rather cumbersome, creating a strong noise during operation. Their centrifuge was similar to a round vessel having high walls. This capacity was propelled by the engine. Electric motors were usually used. The performance of the devices left much to be desired. Much time was spent on removing the oil-cake. As the centrifuge rotated at high speed, as well as to prevent losses due to splashing, the rotating parts were closed with dense lids. Because of this, when removing the cake, it was necessary to disassemble the juicer almost every time. Special difficulties occurred when obtaining juice from fruits that had a thin skin. And when it was required that in the juice there was a fibrous structure, for example, when making tomato juice, the work was very labor-consuming.

However, the producers of juicers continued to improve production. Before them there were two tasks: to relieve the device of vibration and noise, and also to make the unloading of the cake easy. Of course, competition played a role. Consumers preferred to purchase devices more compact, easy to use, reliable.

The greatest difficulty was represented by vibration. It appeared literally right after putting the fruit in the device. They were pressed unevenly to the walls of the centrifuge. There was a shift in the center of gravity. The vibration was so strong that the juicer had to be held on the table. The way out was found. By reducing the weight of the electric motor and determining the most suitable place and method of loading, the load mass was distributed evenly.
