GRONO grain dryers of the Agroteplo Group company belong to the category of mobile modular grain dryers. Structurally, they are made of modules and columns, the number of which depends on the performance declared by the consumer. When designing this dryer, all the advantages and disadvantages of similar analogues were taken into account. Therefore, these grain dryers are reliable, economical and easy to operate and maintain.
Productivity of GRONO grain dryers from 50 to 1000 tons per day.
WORKING PRINCIPLE:
GRONO brand grain dryers are single-module and multi-module, with the number of burners from 1 to 6, and the number of
grains columns from 4 to 13.
The fan injects a flow of air from the environment into the chamber. The air stream is heated by passing through the burner. Next, the heated air passes through an inner chamber 1 m long, ensuring the uniformity of the temperature of the drying reagent at any point of the chamber. The inner chamber is a cylinder with a length of 1 meter, which allows you to place the burner near the very entrance to the grain dryer and prevents the direct flame from hitting the grain columns.
The grain enters the upper hopper, and the auger located there gradually fills the columns. The columns form a jacket around the mine, on which hot air is forced. When all columns are fully loaded, the grain loading auger automatically turns off.
The inner and outer walls of the columns are made in the form of sieves with appropriate perforation, which allows to effectively blow the grain layer (36 cm), maintaining the temperature set by the operator.

In the lower part of the dryer there are dosing rollers, the speed of rotation of which regulates the time the grain stays in the columns. This is what ensures certain drying modes. Dosing rollers feed the dried grain to the lower discharge auger, which transports the grain to the transport systems for further feeding into transport or storage.
CONSTRUCTIVE PERFORMANCE
1. External and internal grates
grain columns are made of AISI430 stainless steel with a thickness of 1 mm, which significantly increases the service life of the unit. The standard drying equipment includes grates with universal perforation of 1.2x20 mm.
2. The supporting chassis is made of galvanized frame. The chassis ensures the rigidity of the dryer structure and the balanced operation of the screws. In the standard configuration, the grain dryer is equipped with support legs, which allows you to install it on a flat concrete base without additional structures.
3. The burner and fan cylinder are painted with high-quality industrial paint and protect the grain dryer from corrosion, thereby extending the service life of the main components of the equipment. All metal parts are galvanized or painted, which guarantees you a long service life of the grain dryer with proper operation, timely cleaning, maintenance and repair.
4. Efficient combustion system: an outer chamber with a length of 1500 mm provides stable air supply to the burner, which is located in an inner chamber with a length of 1000 mm. Thus, the outer chamber does not heat up and all the heat output goes to the dryer. Increased productivity due to an increase in the diameter of the lower burner chamber to 1000 mm.
5. Effective gas burners of our own production are made of heat-resistant stainless steel grade 310 (Chrome) ¦thickness 2 mm with the use of argon welding and contribute to saving gas with high efficiency. The electronic system of ignition and flame control of the burner ensures stable operation of the burner in two-stage mode. The use of burners of this type allows you to save up to 20 percent of gas consumption.
6. Use of highly efficient fans of the Multi-Wing brand manufactured in Denmark.
7. Reinforced fastening of screws made of cast iron with kestamid (Kestamid - tr, a type of wear-resistant polyamide) bushing ensures reliable fixation of the screw and minimal friction in the bearings. Also, in our dryers, the intermediate suspensions of the unloading auger are attached to the structure of the dryer itself, which ensures balanced operation of the unloading auger.
8. The thickness of the auger blade is 3 mm at the base for a longer service life.
9. Dosing rollers are made of hot-drawn aluminum, which is resistant to shocks and breakage.
10. The thickness of the lower screw body is 2 mm.
11. Improved system of attachment of auger pulleys. The bushings are easily mounted on the shaft, then the pulley is just as easily put on them and fixed with two bolts, and dismantled with one bolt.
12. The reinforced transverse frame prevents deformation of the dryer and vibration of the auger. The reinforced design of the chassis allows the dryer to work for many years without deformation of the body and moving parts.
MANAGEMENT AND SECURITY SYSTEM
1. GRONO grain dryers are equipped with a manual and automated control and safety system, which allows you to monitor all parameters of the equipment. The presence of two independent grain dryer control channels significantly increases the reliability of the equipment. In this regard, the failure of the equipment due to the failure of the control system is practically impossible.
2. Measurement of the temperature of the grain and the drying agent is carried out from 6 different points, allowing to obtain reliable information about the drying process. Grain temperature sensors (4 units), located inside the grain columns, and 2 air temperature sensors in the heating chambers.
3. A computer control system with a built-in self-diagnosis system allows you to significantly increase the fire safety of grain dryers. When any sensor of the security system is activated, the grain dryer is immediately disconnected from the gas main and power supply. Gas equipment will ensure safety and reliability of fuel supply.
4. Electromagnetic gas valves of Italian production.
5. Italian-made manual gas valves.
6. A fully automated multi-level security system ensures reliable protection of all equipment nodes in any emergency situations. - disconnection of the burners in case of overheating (complete stop of the dryer and restart) - disconnection of the burners in any emergency situation: power failure, gas supply failure and gas reactivation.
7. Schneider Electric automatic switches ensure reliable protection of all grain dryer systems in any unforeseen situations.
8. The control panel is equipped with Schneider Electric electronics.
