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 an apparatus?
Mobile grain dryers are a small copy of the stationary counterpart. It is a mobile complex, which is often used in large and medium enterprises. The main purpose of the device is to prepare the grain before selling or storing it in storage. Units can operate from liquid or solid fuels, 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 changing 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 productivity. Some modifications can compete with stationary units on equal terms. You can install such equipment yourself in record time (2-3 days). This makes it possible to prevent loss of crop during a sharp change in climate.
Device
The equipment in question operates cyclically. Four main stages can be distinguished in the work:
- Loading grain into the receiver of the unit.
- Heating of raw materials.
- The cooling process.
- Shipment for future 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
The company "AgroTechMash" (ATM) from Voronezh is one of the largest manufacturers in the domestic market. Mobile grain dryers made in Russia, ATM have a wide range, which allows you to choose the option for both small businesses and large agricultural companies. Productivity of cars makes from 20 to 300 tons. Dryers of this brand operate on gas or diesel fuel with an average flow rate of about 60 l / cu. at one o'clock. After drying, the grain is cooled by the supplied atmospheric flow and is ready for unloading.
Another Russian manufacturer, Machine Tool Builder from Yoshkar-Ola, produces grain dryers 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 presents modifications that are powered by an electric drive or power take-off shaft. By performance, cars 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 former Soviet Union. They can work from an electrician or a tractor engine, hold 10-33 cubic meters of grain crops. The main advantage that Agrex mobile grain dryers have is the high efficiency of the heat generator (98%). Profitability is ensured by fuel consumption of about 1 liter per ton of production.
This equipment can be transported using various agricultural equipment. Some models have an automated drying control system. There is an internal separator guaranteeing uniform processing of the entire loaded batch.
Mekmar
This company produces stationary and mobile grain dryers. At the production facilities of the Italian plant under consideration, only systems made using modern technologies with the most automated control are used. Modifications of this brand are distinguished by the principle of operation (telescopic or standard cylinder), power (gas or diesel models).
The Mekmar mobile grain dryer processes raw materials by biological exposure or by processing heated air. Loading of crops into the working compartment occurs through an expansion funnel. Unloading is carried out by means of the lower grill or hinged screw. Almost all modifications from this manufacturer are equipped with an automatic unit for cleaning from extraneous pollution.
Mobile grain dryers Fratelli Pedrotti
This manufacturer is considered the leader in its segment. Units can be powered by an electric motor, and also 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:
- Diesel three-stage nozzle or gas burner.
- The mesh filter for sifting out different breeds of crops (from 0.9 to 2 millimeters in diameter).
- Automatic security system and process control.
- Separate drive unit and integrated thermostats.
- Mechanics and automation, operating at particularly low temperatures.
- Galvanized frame and fire protection system.
A plus of the considered grain dryer is the use of materials resistant to corrosion and mechanical influences, as well as a well-developed lubrication system, the use of modern technologies and high-quality materials in the working and related parts of the configuration.
DIY mobile grain dryer
It is quite realistic to make such a device for your own household with your own hands. The easiest way to choose a drum model. To do this, you need to purchase a cylindrical container and aggregate it with an electric motor, so that the products are dried by rotation inside the tank.
As a working drum, you can use a galvanized pipe of large diameter. In its core, it is necessary to arrange longitudinal ribs that are responsible for the gentle spilling of grain. In any case, the device requires equipping with a rotary 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 the fast equipment of the machine at the place of work and its transportability, which can not be said about stationary counterparts.
Machines for drying various grain crops of domestic and foreign manufacture are widely represented on the domestic market. The most popular models were reviewed above. It is worth noting that mobile grain dryers can not only be bought and quickly mounted, but also made with your own hands. This point is also noted in the review. Due to this diversity, a large agricultural supplier and a representative of individual entrepreneurship can choose a unit. Protection of the crop from unforeseen weather conditions, and the possibility of protecting it for a couple of days, often determine the profitability of the enterprise, the well-being of employees and the provision of the population with basic necessities.
