History

Although there is not much information about this ingenious invention, it is usually attributed to Stephen J. Poplawski, a North American of Polish origin who created a glass mixer, initially known as a vibrator. Based in the American state of Wisconsin , from his childhood he showed an obsession with inventing devices for mixing drinks and in 1922 , after 7 years of experimentation, Poplawski patented a glass mixer, and noted that it was the first device mixer that had a stirrer element mounted on the bottom of a cup, and that mixed malted drinks when the cup was placed in a cavity at the base of the apparatus, although years later, in 1953, was involved in patent litigation, since in 1922 he did not think of the blender for the maceration of fruits and vegetables, but he did as a food grinder, which ultimately earned him the autonomy of the invention. On the other hand, three years earlier in 1950 a Swiss named Roger Perrinjaquet patented the idea of ​​a hand blender and called his creation bamix ,, a portmanteau de “bat et mixe” (bat and mix).

In its origins the Blender was mainly used in hospitals where a medium was needed to crush and mix different medicines and foods. Subsequently, with the massive diffusion of concentrated pills, medical use was reduced and massively spread in homes.

Appearance

Its shape is usually varied but in general it has a container to pour the products, blades or pallets that are in charge of crushing or mixing and an electric motor in charge of providing the necessary mechanical energy to carry out the work, all this united in a plastic casing or metal with electronic switches or contacts that are in charge of programming the speed or operating time according to the operator’s demands.

Types

Basically two fundamental types are recognized, the glass blenders and the hand blenders, commonly known as a hand blender.

In the first group there is a wide range of models, there are small size and small capacity or capacity for large quantities of products on an industrial scale, their shape usually varies greatly, they generally have the motor at the bottom and the glass or container on top attached to the blades or blades, but there are many cases in which the motor also appears on top or to the side and the blades, blades and other devices in charge of mixing are introduced from the top.

In the case of hand blenders, although various models can be found, its principle of operation is based on the fact that the operator directly supports the equipment with freedom to insert it into the container where the food is prepared, not depending on one specific for its function and it can also change the blades or devices that mix the products, adapting the machine for various functions, within which crushing is generally ruled out.
