Description

The proposed method relates to the technology of conservation of agricultural products, mainly freshly harvested feed grain.

Preserving the grain mass in the absence of air access is almost the only way that eliminates the need for heat drying.

A known technology for preserving agricultural products, mainly grain, including laying in an airtight storage and periodic treatment with an insecticide by pumping recirculated air through a container with propionic acid [1], which provides the artificial creation of an aggressive environment that excludes the processes of aerobic and anaerobic respiration. This method of preservation allows you to ensure the safety of agricultural products, in particular grain, but complex equipment is required and the possibility of the influence of harmful factors from the use of preservatives on the maintenance staff with the possible likelihood of poisoning people in the process of servicing the storage and processing of processed products.

A known method of preserving agricultural products under anaerobic conditions, mainly whole grains, including laying in sealed containers [3] and ensuring the preservation of the grain by self-preservation, which occurs in the process of replacing oxygen in the intergranular space with carbon dioxide released during breathing. However, this method of self-preservation is quite long, as it is based on the natural process of respiration.

The objective of the invention is to accelerate the effect of self-preservation by increasing the intensity of anaerobic respiration.

It was established [4, p. 34] that the intensity of anaerobic respiration increases significantly - 1.5-2 times in the case of grain injury - chips, cracks and other injuries.

Thus, for the most rapid onset of the process of self-preservation of the grain mass, it is necessary to provide artificially the maximum intensity of the process of anaerobic respiration of the grain.

The process of anaerobic respiration is described by the following equation for the dissimilation of organic substances, mainly sugar:

C ₆ H ₁₂ O ₆ = 2CO ₂ + 2C ₂ H ₅ OH + energy.

At the same time, a significant amount of carbon dioxide and ethyl alcohol is released, leading to a loss of grain viability and its self-preservation. The released energy is spent for intracellular work and self-heating of intergranular space, which can lead to spoilage of grain in case of violation of the tightness of the container.

The maximum intensity of the process of anaerobic respiration is achieved when the integrity of the integumentary tissue of the grain is destroyed.

To obtain such a technical result, freshly harvested feed grain is preliminarily subjected to a technological treatment that destroys the integument.

The drawing shows a functional diagram of the proposed method for the effective conservation of freshly harvested feed grain under anaerobic conditions. The scheme contains a special device for the destruction of the integrity of the integumentary grain tissue 1, the loading device of the containers 2 and sealed containers for storage 3.

The proposed method is carried out in the following sequence:

Agricultural products, for example, freshly harvested feed grain coming from the field from the combine, are subjected to forced destructive action of integumentary tissues with a special device and then loaded into airtight containers with the most complete exclusion of supergrain space. As a result of the destruction of the integrity of the integumentary tissues of the grain, there is a significant increase in the process of anaerobic respiration and, accordingly, the release of carbon dioxide, which, as the heaviest compared to other gases contained in the intergranular and supergrannous spaces, displaces them, creating conditions for quick self-preservation and long-term storage.
