Mobile grain dryers: overview, manufacturers, types and reviews

In the domestic market, mobile grain dryers appeared relatively recently. In Europe, such units have been used for several decades. 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 device?

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

The main advantage of this technique is the possibility of delivering it to the most remote areas of the economy. With a changeable and harsh climate - this is very important. Such an aggregate can save the crop from wetting or frost. Mobile grain dryers have a fairly high productivity. Some modifications can compete on an equal footing with stationary units. You can install such equipment yourself in record time (2-3 days). This makes it possible to prevent the loss of crops during a sharp change in climate.

Device

The equipment under consideration functions cyclically. There are four main stages in the work:

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

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

Domestic production

Enterprise "AgroTechMash" (ATM) from Voronezh is one of the largest manufacturers in the domestic market. Mobile grain dryers of Russian production ATM have a wide range of models, which makes it possible to choose an option for small business as well as for a large agricultural company. The productivity of machines is from 20 to 300 tons. Dryers of this brand operate on gas or diesel fuel with an average flow of about 60 l / cu. at one o'clock. After drying, the grain is cooled by the supplied atmospheric flux and is ready for unloading.

Another Russian manufacturer - "Stankostroitel" from Yoshkar-Ola - produces grain drying machines under the name "Gulliver-3". Thanks to the use of high-quality Italian materials, designers have been able to reduce the cost of equipment without loss of productivity. In this series, modifications are provided that operate from an electric drive or a power take-off shaft. In terms of productivity, the machines are divided into three groups: a capacity of 15.19 and 25 cubic meters. M.

Agrex

Units from this Italian company are sold in almost all countries of the post-Soviet space. They can work from an electrician or a tractor engine, they can accommodate 10-33 cubic meters of grain crops. The main advantage that Agrex mobile grain dryers have is a high efficiency of the heat generator output (98%). The economy is provided by fuel consumption of about 1 liter per ton of products.

Transportation of this equipment is possible with the help of various agricultural machinery. Some models have an automated drying control system. There is an internal separator, which guarantees uniform processing of the entire loaded batch.

Mekmar

This company produces stationary and mobile grain dryers. At the production facilities of the Italian plant in question, only systems that are modernized with the most automated control are used. Modifications of this brand differ in the principle of operation (telescopic or standard cylinder), power (gas or diesel models).

The mobile grain dryer "Mekmar" processes the raw material by biological action or by treatment of heated air. Loading of cultures into the working compartment occurs through the expansion funnel. Unloading is performed by means of a lower grate or a swivel auger. Virtually 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, and also equipped with an integrated burner for diesel fuel, or an analogue with a heat exchanger or a gas feed.

The standard equipment of the equipment brand in question consists of the following elements:

1. A diesel three-stage injector or gas burner.
2. A grid filter for screening different types of cultures (from 0.9 to 2 millimeters in diameter).
3. Automatic security system and control of the process.
4. Separate knot of drives and built-in thermostats.
5. Mechanics and automation, working under extremely low temperatures.
6. Galvanized frame and fire protection system.

The advantage of the grain dryer in question is the use of materials resistant to corrosive and mechanical influences, as well as a well-developed lubrication system, the use of modern technologies and high-quality materials in the working and associated parts of the assembly.

Mobile grain dryers with own hands

Such a device for their own farming can be produced by own hands. 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 the product by rotating inside the tank.

As a working drum, a galvanized large diameter pipe can be used. In its core, it is necessary to arrange longitudinal ribs, which are responsible for sparing grain spillage. In any case, the device requires a rotary mechanism, which can be an electric motor and generator with the ability to supply warm or cool air inward to accelerate the processing of products.

User Reviews

Owners of the considered devices note their high efficiency along with an acceptable price. To the advantages of mobile grain dryers, users attribute a fast machine configuration to the workplace and its transportability, which can not be said for stationary analogues.

In the domestic market, machines for drying various grain crops of domestic and foreign manufacture are widely represented. The most popular models were discussed above. It is worth noting that mobile grain dryers can not only be bought and quickly mounted, but also made by themselves. This point is also noted in the review. Due to this variety, a large agrarian supplier and a representative of individual entrepreneurship can choose the unit. Protecting the crop from unforeseen weather conditions, and the possibility of protecting it in a couple of days, often determine the profitability of the enterprise, the welfare of employees and the provision of basic necessities to the population.
