Grain aerator Kozak-2 for grain drying and cooling

Grain aerator "Kozak-2" from the manufacturer TechnoMashStroy is reliable industrial equipment for active ventilation, drying, and cooling of grain mass during long-term storage. The device effectively handles wheat, corn, rapeseed, sunflower, flax, soybeans, and other cereal, oilseed, and legume crops, ensuring stable raw material quality without the need for transportation.

Purpose and advantages

The aerator is used to reduce grain moisture and temperature, eliminate "hot spots" (self-heating zones), prevent mold, fungi, and pests, and prepare seed material for sowing by preheating. Thanks to active ventilation, the grain "breathes," and temperature and humidity are evenly distributed throughout the entire depth of the pile, extending the period of quality storage.

Design and operating principle

Structurally, the aerator consists of an aeration pipe and a high-pressure centrifugal fan that creates an airflow to blow through the grain mass. The aeration pipe is screwed into the grain pile, and the fan ensures effective cooling and "venting" of the grain. The device operates in two modes — air blowing and suction — allowing flexible adaptation of the process to specific storage conditions.

Technical specifications

• Motor power: 1.5 kW (3000 rpm).
• Total length of the grain ventilator: 2525 mm.
• Spear length (without extension): 1793 mm.
• Length of the perforated section: 1058 mm.
• Extension insert length: 1000 mm.
• Perforation diameter: 3 mm (holes of other diameters can be manufactured upon customer request).
• Impeller diameter: 200 mm.
• Pipe diameter: 140 mm.
• Operating modes: air blowing and suction.

Configuration for 220V and 380V

Aerator "Kozak-2" is available in two power supply versions, allowing you to choose the optimal solution for any farm:

1. 220V: electric motor with a frequency converter and a 220 V plug.
2. 380V: electric motor with a magnetic starter and a 380 V plug.

Both versions have identical technical parameters and performance, differing only in the type of connection to the power grid.

Application

"Kozak-2" aerators are widely used at grain floors, in elevators, grain storage facilities, and warehouses. They are ideal for owners of small and medium-sized grain storage facilities, providing a professional level of ventilation and drying without the need for complex installation or additional structures.
