GRAIN DRYERS FOR CONTINUOUS CYCLE ASTRA-Ingul «11 / 3.6, Киев

Dryers are designed for drying of grains, legumes, oil crops of seed, food and fodder purposes.

Appointment
Dryers are designed for drying of grains, legumes, oil crops of seed, food and feed use in conditions of constant technological platform. Dryers ASTRA Ingul similar in construction to the well-known firms dryers «MEYER ENERGY MISER» (BROCK, USA) and «MECMAR» (Italy) — the best tower dryers in the world, but surpass them in a number of indicators, including efficiency and high reliability. This allows the dryer ASTRA Ingul compete successfully with imported equipment.
Dryers ASTRA Ingul reliable, user friendly, save energy, provide high-quality grain drying, and rapid return on investment.

Description and composition of the dryer
Dryer tower is shaped like a cylinder with double walls, formed of perforated sheet of stainless or galvanized steel. The cylinder is divided into several sections of the ring. The distance between the grids of 30 cm between the grids in sections radially mounted vertical plates, dividing the space of grain into twelve sectors (wells). In the top part of the technological drive of grain fed to the external noriey.
On the roof of the dryer is installed aerodynamic separator pre-cleaning grain SPO-ASTRA-50 to provide continuous cleaning of grain moisture. The dust is removed and the recycling of grain in the dryer. In the process of drying grain from a reservoir by gravity flow, by gravity, passes down between the mesh walls with passive mixers and into the device selection of dry grain with blades rotating at variable speeds, and then noriyu.
During movement between the grids first grain is heated and then cooled by air flow. Air is sucked from the surrounding space axial centrifugal fan through a layer of heated-cooled grain, picking at the same time it has the warmth and moisture, then mixed with hot air from the burner (recovery) and is fed under pressure into the heating zone of grain, which gives off heat. Occurs as heat recovery using heat engine fan installed inside the dryer. This helps reduce fuel consumption by 30%.
Manholes for maintenance dryers allow you to change the structure of the dryer — the ratio of grain size of the heating zone and its zone of aeration (cooling), which allows to optimize the dryer. For example, when drying corn high moisture content appropriate to increase the length of the heating zone up to 100%, followed by cooling the grain in a separate ventilated bunker, which significantly improves productivity and quality of grain.
In the case of the seed, creating a fire hazard, such as sunflower seeds, purging (cooling) of the grain layer at the exit of the dryer is a separate auxiliary fan installed in the ventilation chamber and do not work on the suction and blowing on the flow, So that dust from the grain layer does not fall into the hot zone of the dryer. Dryer safe!
External monoblock burner operates on liquid fuel or gas. The combustion products are mixed with the air flow from the main fan and come inside the shell dryer. Dryer is equipped with temperature sensors grains in several areas, temperature sensors, hot air, air pressure sensors on the inlet and outlet of the fan. Installation of a humidity sensor in the flow of grain output. Special measures are taken to prevent fires (aspiration system at the entrance, preventing the absorption and accumulation of dust located outside the hot zone of the fan drive selector grain and burner).
The outer shell dryer does not have hatches and manholes, service and cleaning inside are made with a convenient and safe access into the interior of the dryer from the bottom, through the ventilation chamber. External cleaning nets upper section is made with a circular catwalks. The main fan can retreat to the side that makes it easy to handle faucet. Main details dryers galvanized or stainless steel.
Grain sampler carousel is the only mechanism of drying. It consists of a wheel with rollers on a circular rail, spiral blades and the annular scraper conveyor. The speed of shipment is given a frequency converter. Maintenance of all the mechanisms selector performed outside the dryer.
