The cooler can be used in individual farms, mills, elevators and other enterprises of the agro-industrial complex and the food industry in technological lines.
GRAIN COOLER ADVANTAGES:
- High reliability;
- Quality materials from leading European manufacturers;
- Low specific power consumption – 0.3 kW / h per ton of cooling grain;
- Easy to manage and maintain;
- Quick installation.
The cooler body is made of galvanized steel grade S280GD + Z 275g / m2; MA; C; O EN 10346/09.
The service life of the cooler is at least 20 years.
Equipment warranty – 12 months.
Chiller consists of:
- cooling tower;
- top bin.
The base is located at the bottom of the cooler and is a welded metal frame on which sections of the cooling column are installed from above. At the base, directly under each shaft along the entire length, there are exhaust mechanisms driven by a geared motor, which, during operation, rotating, rake off grain from under the mines and dump it into the lower hopper.
At the base, above the exhaust mechanisms, there are emergency unloading hatches. They are designed for emergency unloading of grain from a de-energized cooler during a fire.
Also on the side, at the base of the emergency unloading hatch, there is a sensor designed to measure the temperature of chilled grain at the outlet from the cooler.
The cooling column consists of two parallel vertical shafts installed on the base. Shafts consist of holding and cooling sections. Axial fans are located in three cooling sections.
Vertical channels with perforated walls are structurally located inside each cooling section.
The space between the shafts forms an exhaust chamber.
On both sides, from the suction side of the ambient air, the sections are covered with casings.
The upper hopper is located above the column. In the upper part there is a hatch and two brackets for installing level indicators, and in the lower part there is a distributor that closes the exhaust chamber from above and directs the grain flow through two shafts. The hopper serves to create a hydraulic seal and ensures continuous operation of the cooler during short-term interruptions in the grain supply.
How it works
Dry heated grain with the help of a bucket elevator or other transport mechanism is fed from above to the cooler, fills the mines and the upper hopper. The grain level is controlled according to the readings of the level indicators in the hopper. Level switches measure the maximum and minimum levels of grain backfill.
During operation, the fans suck in atmospheric air from the outside, blow it through the grain in vertical channels and throw it out through the exhaust chamber.
The grain, moving from top to bottom, is cooled and then enters the outlet mechanisms.
The frequency of rotation of the exhaust mechanisms is smoothly changed using an electronic frequency converter and is set from the control panel. Thanks to this, it is possible to regulate the speed of movement of the grain and the intensity of cooling.
Exhaust mechanisms supply grain to the lower hopper, from where it goes to external transport mechanisms.
