Description

The claimed utility model relates to agricultural machinery, namely to devices for drying agricultural crops, for example, food and seed grain of cereals, legumes and oilseeds, as well as forage grasses, vegetables and fruits, and can be used in large and small agricultural and grain processing enterprises when preparing grain for storage, as well as at enterprises of the agro-industrial complex.

From the prior art, a mine block grain dryer is known, selected as the closest analogue, containing bins, drying and cooling vertical chambers, supply and discharge boxes, along the entire height of the mines for supplying and removing cooling air, the boxes consist of channels of two vertical perforated plates, perforations the plates of the boxes are made in the form of slots with a convexity outward, the space between the plates of adjacent supply and output boxes is intended for filling the materials to be dried, the supply and output boxes are arranged alternately at equal intervals between them, the perforations of the plates of the boxes are made in the form of arched slots with a bulge outward. On the side of the supply ducts, a supply manifold is installed for supplying a drying agent, on the side of the outlet ducts - an outlet collector, ducts of a mine dryer and a cooling chamber in the form of two vertical perforated plates converging at an acute angle. (IPC В02В 1/08 (1995.01) F26B 17/10 (1995.01). Application: 94002964/06, 26.01.1994. Date of publication of the application: 10.03.1996).

The disadvantage of the closest analogue is the lack of additional means of disinfection, which increases the percentage of product loss during storage of an agricultural crop, leads to a reduction in the long-term storage of an agricultural crop, which often creates the need for a separate procedure aimed at stopping microflora on a dried crop.

The technical result of the claimed utility model is to simplify the process of preparing grain material for storage and processing, increase the shelf life and increase the degree of disinfection of the dried agricultural crop, which minimizes the need for a separate procedure aimed at stopping the microflora on the processed crop.

The technical result is achieved by creating a mine grain dryer, consisting of a grain dryer shaft and an unloading hopper, where an ozonizer, an ozone concentration sensor directed to the ozonizer, an ultraviolet source, an ultraviolet radiation intensity sensor directed to an ultraviolet radiation source are additionally installed.

The products enter the grain dryer, completely filling the grain dryer shaft, where the drying process takes place with subsequent cooling of the products, then the grain enters the unloading hopper, during the unloading process, the products are processed with ozone, disinfecting harmful microflora, as a result of which microbes and bacteria that have settled on the processed material die. mold, bending and similar microflora, as well as additional grain is disinfected by exposure to ultraviolet radiation. The ozone concentration sensor sends a signal to the control unit located outside the grain dryer, which makes it possible to adjust the ozonation mode depending on the humidity, mass and temperature of the processed agricultural products. An ultraviolet radiation intensity sensor sends a signal to a control unit located outside the dryer, making it possible to monitor the intensity of ultraviolet radiation, allowing you to determine the need to clean the lamp from contamination.

The claimed utility model is illustrated by the following schematic illustration.

The positions indicated mean the following:

1 - grain dryer mine;

2 - unloading hopper;

3 - ozonizer;

4 - ozone concentration sensor;

5 - a source of ultraviolet radiation;

6 - ultraviolet radiation intensity sensor.

The declared mine grain dryer consists of a grain dryer shaft 1, an unloading hopper 2, where an ozonator 3 is additionally installed, an ozone concentration sensor 4 directed to the ozonizer, an ultraviolet radiation source 5, an ultraviolet radiation intensity sensor 6 directed to an ultraviolet radiation source.

A mine grain dryer with the function of grain disinfection operates as follows.

The products enter the grain dryer, completely filling the shaft of the grain dryer 1, where the drying process takes place, followed by the cooling of the products, then the grain enters the unloading hopper 2, during the unloading process, the products are processed with ozone from the ozonator 3, disinfecting harmful microflora, as a result of which those who settled on the processed material, microbes, bacteria, mold, bending and similar microflora, as well as the grain is additionally disinfected by exposure to ultraviolet radiation from an ultraviolet radiation source 5, the ozone concentration sensor 4 sends a signal to the control unit located outside the mine dryer, which allows you to adjust the ozonation mode depending on from moisture, mass and temperature of the processed agricultural products, the UV intensity sensor 6 makes it possible to control the intensity of UV radiation, sending a signal to the control unit located outside the shaft dryer, allowing I determine the need to clean the lamp from contamination.

The application of the declared useful model in the field of agriculture will simplify the preparation of grain material for storage and processing, increase the degree of disinfection and increase the shelf life of the processed agricultural crop.
