Mobile grain dryers have appeared on the domestic market relatively recently. In Europe, such units have been used for more than a dozen years. Modern equipment makes it possible to reduce production costs and improve product quality. Consider the types of devices, their features and manufacturers, as well as user reviews.

What is the machine?

Mobile grain dryers are a reduced copy of a stationary counterpart. It is a mobile complex, which is often used in large and medium-sized enterprises. The main purpose of the device is the preparation of grain before selling it or storing it in storage places. The units can operate from liquid or solid fuel, depending on the type.

The main advantage of this technique is the ability to deliver it to the most remote areas of the economy. In a changeable and harsh climate, this is very important. Such a unit can save the crop from getting wet or freezing. Mobile grain dryers have a fairly high performance. Some modifications can compete on equal terms with stationary units. You can install such equipment yourselfin record time (2-3 days). This makes it possible to prevent crop loss during a sudden change in climate.

Device

The equipment in question functions cyclically. The work can be divided into four main stages:

1. Loading grain into the receiver of the unit.
2. Heating raw materials.
3. Cooling process.
4. Shipment for further use or transportation.

All stages of processing are controlled by special devices. The result is a high-quality product with minimal labor and energy costs. Mobile grain dryers can be powered by an electric, solid fuel or liquid engine. Some variations are aggregated with a tractor motor, which allows them to be used directly during urgent harvesting. The equipment can process from 40 to 300 tons of grain per day.

Domestic production

Enterprise "AgroTechMash" (ATM) from Voronezh is one of the largest manufacturers in the domestic market. Russian-made mobile grain dryers ATM have a wide range of models, which allows you to choose the option for both small businesses and large agricultural companies. The capacity of the machines ranges from 20 to 300 tons. Dryers of this brand operate on gas or diesel fuel at an average consumption of about 60 l / cu. in hour. After drying, the grain is cooled by the supplied atmospheric flow and is ready for unloading.

Another Russian manufacturer - "Machine Tool" fromYoshkar-Ola - produces dryers for grain under the name "Gulliver-3". Thanks to the use of high-quality Italian materials, the designers managed to reduce the cost of equipment without losing productivity. This series includes modifications powered by an electric drive or a power take-off shaft. By performance, machines are divided into three groups: with a capacity of 15, 19 and 25 cubic meters. m.

"Agrex" (Agrex)

Units from this Italian company are sold in almost all countries of the post-Soviet space. They can be powered by electrics or a tractor engine and can hold 10-33 cubic meters of grain crops. The main advantage that Agrex mobile grain dryers have is the high return efficiency of the heat generator (98%). Profitability is ensured by fuel consumption of about 1 liter per ton of products.

This equipment can be transported using various agricultural machinery. Some models have an automated drying control system. There is an internal separator to ensure uniform processing of the entire loaded batch.

Mekmar

This company manufactures stationary and mobile grain dryers. At the production facilities of the Italian plant in question, only systems made using modern technologies with the most automated control are used. Modifications of this brand differ in the principle of operation (telescopic or standard cylinder), power supply (gas ordiesel models).

Mekmar's mobile grain dryer processes raw materials by biological action or heated air treatment. The cultures are loaded into the working compartment through an expansion funnel. Unloading is carried out by means of the lower grate or articulated auger. Almost all modifications from this manufacturer are equipped with an automatic cleaning unit from foreign contaminants.

Fratelli Pedrotti mobile grain dryers

This manufacturer is considered the leader in its segment. The units can be powered by an electric motor, as well as equipped with a built-in burner for diesel fuel, or an analogue with a heat exchanger or gas supply.

Standard equipment of the considered brand of equipment consists of the following elements:

1. Diesel three-stage nozzle or gas burner.
2. Mesh filter for screening different types of crops (from 0.9 to 2 millimeters in diameter).
3. Automatic security system and process control.
4. Separate drive unit and integrated thermostats.
5. Mechanics and automation operating at extremely low temperatures.
6. Galvanized frame and fire protection system.

The advantage of the considered grain dryer is the use of materials resistant to corrosion and mechanical stress, as well as a well-developed lubrication system, the use of modern technologies and high-quality materials in working and related partsconfiguration.

Do-it-yourself mobile grain dryer

It is quite possible to make a similar device for your own household. The easiest way to choose a drum model. To do this, you will need to purchase a cylindrical container and aggregate it with an electric motor to ensure the drying of products by rotating inside the tank.

A large-diameter galvanized pipe can be used as a working drum. In its core, it is necessary to place longitudinal ribs responsible for the gentle pouring of grain. In any case, the device requires a rotating mechanism, which can be an electric motor and a generator with the ability to supply warm or cool air inside to speed up the processing of products.

User reviews

The owners of the devices in question note their high efficiency along with an affordable price. The advantages of mobile grain dryers include quick assembly of the machine at the place of work and its transportability, which cannot be said about stationary counterparts.

In the domestic market, machines for drying various grain crops of domestic and foreign manufacture are widely represented. The most popular models have been discussed above. It is worth noting that mobile grain dryers can not only be bought and quickly installed, but also made by hand. This point is also noted in the review. Thanks to thisdiversity, a large agricultural supplier and a sole proprietorship can choose an assembly. Protecting the crop from unforeseen weather conditions, and the ability to protect it in a couple of days, often determines the profitability of the enterprise, the well-being of employees and the provision of the population with essential products.
