The article talks about what an elevator is, how the work of a grain elevator works, and what other meanings this word carries.
Equipment
Probably the most important plant crop is the cereal variety. And especially wheat, barley and rye. Our ancestors began to cultivate and grow them tens of thousands of years ago. They quickly realized that it was far more profitable and productive to breed them themselves than to be content with rare finds of wild wheat and more. That is how the first agriculture appeared.
Cereals remained the most important food resource throughout human history. But gradually, with the growth of the population and the beginning of the era of industrialization, new methods of collection, processing and storage were required. And the most common technical complexes that do this are called elevators. True, this word has several more meanings, but about everything in order. So what is an elevator? We’ll talk about this.
Definition
If you look into the encyclopedia, it will become clear that the elevator is a special technological construction, designed to serve for storing large quantities of various grains, primary processing or bringing to a certain condition. Simply put, this is a mechanized silo-type grain storage . So now we know what an elevator is. But consider the device of such complexes in more detail.
Device
Most often, such complexes include silos, special devices for loading and unloading (which are also called elevators, but arranged a little differently), work buildings, grain drying shops, and so on. Separately, it is worth mentioning the silo tanks of an impressive volume - from 11 to 48 thousand tons. But unlike silos, where tops or grass for animals are stored, grain elevators are equipped with disinfection devices for the stored grain, good ventilation, in a word, all that will preserve its presentation.
Currently, all such complexes, in addition to storage and service devices, also have points of automobile or railway unloading and loading. Simply put, now this is done by automation, a special conveyor, which is also called an elevator and serves for the continuous loading of bulk or small-sized cargo in a vertical or inclined surface. So we figured out what an elevator is.
History
The first elevators began to appear in the mid-end of the XIX century. It was then that technologists began to develop more productive methods for storing and primary processing of grain (drying, cleaning from debris, insects, etc.). This was due to the fact that in connection with the constantly growing population of the earth, grain, as well as other products, was required more and more, and it was impossible to use ancient methods for its harvesting and harvesting, and the work of the elevator accelerated grain harvesting. True, at the first such complexes loading was carried out manually. Something similar can be seen in some old films, where workers throw grain on a moving belt with shovels. Now we know what an elevator is.
Cost
According to average estimates, the cost of a grain elevator is calculated at the rate of $ 200 per ton of raw materials for all other costs. Simply put, the turnkey price varies greatly and directly depends on how much grain the complex can store and process. Grain elevators can also be equipped with various auxiliary equipment at the request of the customer. Naturally, then the price increases greatly.
Other values
In every language that is alive, and people actively communicate in it, there are words that have several meanings at once. And usually the older they are, the more actions or things they indicate. And the word "elevator" is one of them. We discussed its grain variety, but now we will consider other meanings.
An elevator is also called a special medical tool that is used in maxillofacial surgery and dentistry.
This word includes many automated devices whose purpose is the continuous loading of a load in a vertical or inclined direction. For example, an artillery elevator on warships provides the supply of shells to guns. And on aircraft carriers - this is a special lifting device that transports aircraft to the take-off deck.
But most often when mentioning this word, of course, they mean the grain storage complex. And the older generation perfectly remembers those times when in the years of the USSR students and schoolchildren were involved in public work at such a grain storage as an elevator. Photos of them are almost always shown by large silo containers or loading summer, along which the grain moves.
