Problems solved by technology

However, most of the physical and chemical methods are aimed at anti-mildew treatment after the grain is put into storage, and need to be operated in the grain storage. Constrained conditions, poor anti-mildew effect
[0005] On the other hand, if initial fungal contamination occurs in the newly harvested grain during transportation, it is difficult to kill or remove it

Embodiment 1

[0018] A biological mildew-proof granule suitable for high-water dispersion grain transportation and its use method. The composition and weight of the granule are as follows: 3% natamycin, 10% allicin, 30% borax, 55% diatomaceous earth, hard Magnesium fatty acid is mixed with 2% to make particles with a particle diameter of about 2mm and dried. When the newly harvested high-moisture corn (moisture content 17%) is loaded by train, a layer of anti-mold granules is evenly sprinkled on the surface of the loaded high-moisture corn. A single carriage carries 50 tons of corn, and the amount of anti-mold granules is 25 kg. The roof of the carriage is covered with tarpaulin to prevent rain and moisture, and the transportation time of corn is 7 days. When the corn arrives at the destination for unloading and warehousing, it needs to be cleaned to remove the mixed anti-mildew particles.

Embodiment 2

[0020] Another biological mold-proof granule suitable for high-water dispersion grain transportation and its use method. The composition and weight of the granule are: 3% natamycin, 4% allicin, 30% borax, 60% diatomaceous earth, 3% magnesium stearate is proportioned to make granules with a particle diameter of 0.8-1mm, and dried. When the newly harvested high-moisture rice (moisture content 16%) is loaded by train, a layer of anti-mold granules is evenly sprinkled on the surface of the loaded high-moisture rice. A single carriage carries 50 tons of rice, and the amount of anti-mold granules is 30 kg. The roof of the carriage is covered with tarpaulin to prevent rain and moisture, and the transportation time is 3 days. When the rice arrives at the destination for unloading and storage, it needs to be cleaned to remove the mixed anti-mildew particles.

Embodiment 3

[0022] Another biological anti-mildew granule suitable for high-water dispersion grain transportation and its use method, the composition and weight of the granule: 1.5% natamycin, 8.5% allicin, 40% borax, 48% diatomaceous earth, Calcium stearate is mixed with 2% to make granules with a particle diameter of 0.5-1mm, and dried. When the newly harvested high-moisture wheat (moisture content 16.5%) is loaded by a special grain vehicle, a layer of anti-mold granules is evenly sprinkled on the surface of the loaded high-moisture wheat. The carriage contains 25 tons of wheat, and the amount of anti-mold granules is 10 kg. The roof of the carriage is covered with tarpaulin to prevent rain and moisture, and the transportation time is 2 days. When the wheat arrives at the destination for unloading and warehousing, it needs to be cleaned to remove the mixed anti-mildew particles.

Abstract

The invention discloses biological mould-proof granules suitable for transporting high-moisture bulk grains, and a using method of the biological mould-proof granules. The biological mould-proof granules comprise the following components by weight percent: 1-4% of natamycin, 5-15% of allicin, 18-45% of borax, 35-65% of kieselguhr and 2-5% of magnesium stearate or calcium stearate. The biological mould-proof granules have the particle sizes of 2-0.5mm and the density (volume weight) of more than 800kg / m<3>. When the bulk grains are transported by a vehicle, a layer of mould-proof granules are evenly spread on the surface layers of the loaded high-moisture bulk grains, wherein 0.2-1kg of mould-proof granules are used for every ton of bulk grains; after the grains are loaded, impurities are removed before the grains are put into storage, so that the mould-proof granules mixed into the grains can be removed. The mould-proof granules can go deep into the stacked grains, thus being stable and lasting in mould-proof effect; the mould-proof granules are free from toxicity and simple in components, thus being used in the transportation process.

Description

[0001] technical field [0002] The invention belongs to the technical field of grain logistics safety, and specifically relates to a biological mildew-proof particle suitable for high-water dispersion grain transportation and a use method thereof. Background technique [0003] During the grain harvest season, the water content of newly harvested grains is relatively high, and most grains are transported long-distance to storage warehouses without timely precipitation and drying treatment. It is resistant to storage, and its quality is also prone to deterioration. [0004] Existing grain anti-mildew methods mainly include physical methods such as cryopreservation, controlled atmosphere, vacuum, ionization, and negative ion generation, and chemical fumigation such as phosphine, ethyl formate, and carbon oxysulfide (COS). However, most of the physical and chemical methods are aimed at anti-mildew treatment after the grain is put into storage, and need to be operated in the gr...
