Electric Minelvaton recirculation low-temperature semanatorile

Description

Designed and manufactured a new semanatorile, running on electricity and technology of drying of grains and seeds moderately heated air.

Modes of drying technology provided the original design and equipment dryers, equipped with recirculation systems, loosening and mixing of the mound, feeding, heating and cooling, monitoring temperature and humidity of grain and other Cross purge flow the loosened layer of grain air at variable temperatures drying allows quickly and evenly remove moisture from the grain as with external and internal the layers.

Advantages developed technologies:

• energy independence through the use of electricity instead of fossil fuels;

• gentle and uniform aeration drying of grain and seeds almost any cleaning humidity temperature conditions close to the natural;

• energy efficiency for the expense of combined drying of the grain is heated and ambient air;

• environmental the purity of the grains and seeds are not contaminated (as in gas dryers products combustion of the fuel;

• quality drying unripe grain harvested from the field for 1-2 weeks ahead of time.

Advantages electric dryer in comparison with high-temperature gas:

• low-temperature drying varietal seeds;

• environmentally friendly drying grain and, as a consequence, grain products (bread, pasta, etc);

• reduction operating costs due to the replacement of natural gas for electricity 1.5 times;

• increase grain quality and excluding the heat of his injury during heat drying due to the subsequent step of dried beans 2-3% in electric the dryer;

• profitability the electric dryers in all regions, regardless of the availability of natural fuel;

• the reduction of losses wet grain with average 20% to natural 5% at the expense of quality drying and increase the drying capacity due to be available for the farmer prices dryer (1.8 times cheaper than gas) and operation (1.5 times cheaper gas).

The proposed technology aeration drying and design electric dryers are protected by a U.S. patent and international application.

Area application

Electric dryer and combined technology drying grain designed for use in farming and seed the farms. The dryer can operate both in the structure of the Elevator, and as Autonomous grain drying complex.

Stage testing

Manufactured and assembled on a Foundation of experienced the drying plant with a capacity of corn ~4 tons of grain (see photo).

Set on the outskirts, Dnepropetrovsk, works with 1 September 2013

The installation includes a hopper, Elevator tower, vertical Elevator, dryer silo equipped with a heater new type systems air flow and gravity flow for receiving, handling and shipment to the customer conditioned grain. It is possible to install cleaner grain.

The tests were performed on a commodity corn humidity 22.5 to 25% and varietal seeds of sunflower and maize humidity respectively 12,5% and 20.5% at an average ambient temperature of 6-10° C and the relative humidity of 90-100%. When drying commodity corn grain temperature did not exceed 45° C, and sunflower seeds and corn - 36° C. Commodity corn was dried to 12.5% for 2 hours, and sunflower seeds and corn, respectively, to 7% and 13.5% for the 2.5 and 3 hours.

Field test results showed that development structure of the dryer and technology, providing high quality and environmentally friendly products higher germination. The cost of drying grain does not exceed $1,3, and seeds - $1,8 when removing 1 t% moisture.
