Embodiment 1

[0027] The corn has not been subjected to precipitation treatment after harvesting in the production area. The moisture content measured by the rapid moisture analyzer reaches 20%. If the precipitation is not timely, it will generate pile heat and mildew during the transportation of vehicles (cabins), and it is easy to cause Mildew and hardening affect the quality of grain and the performance of grain storage. The carbon dioxide slow-release agent needs to be used after the high-moisture corn is harvested and before the vehicle (hold) is loaded. It is packed and transported in train wagons with a loading capacity of 60 tons. Use 4kg of attapulgite clay and 3kg of bentonite to grind the powder, the particle size is 0.05mm, and dry in an oven at a temperature of 110°C. Baking soda 2.4kg granules are mixed evenly. Packed in breathable non-woven fabric, each 2kg, can be fixed and distributed in the bottom of the train carriage with a magnetic breathable container, and 6 points a...

Embodiment 2

[0029] The difference from Example 1 is that the raw grain is rice (japonica rice), the moisture content is 17% when harvested in the place of production, and it is packed and transported by train wagon. Use 2kg of attapulgite clay and 2kg of bentonite to grind the powder, the particle size is 0.15mm, and dry in an oven at a temperature of 105°C. Soda 2kg granules and mix well. Packed in breathable non-woven fabric, each 1kg, can be fixed and distributed on the bottom of the train carriage with a magnetic breathable container, and 8 points are evenly distributed. Then it is filled with paddy and transported normally for 7-14 days.

Embodiment 3

[0031] The difference from Example 1 is that the raw grain is rice (japonica rice), the moisture content is 19% when harvested in the place of origin, and it is transported by ship with a capacity of 10,000 tons. Use 200kg of attapulgite clay and 200kg of bentonite to grind the powder, the particle size is 0.5mm, and dry in an oven at a temperature of 90°C. After drying, the powder is cooled to room temperature at 15°C, and mixed with 220kg of citric acid particles and 180kg of baking soda particles. uniform. Packed in sacks, stacked with three layers of sacks, each bag is 80kg, and there are 10 points on the bottom of the ship. After the points are evenly distributed, the grains will be loaded and transported for 7-14 days.

Abstract

The invention discloses a method for suppressing mildewing in a high-moisture grain loading logistics process. The high-moisture grain loading logistics process consists of a carbon dioxide controlled-release agent and a carrier, wherein the carrier component consists of attapulgite and bentonite; the carbon dioxide controlled-release agent is prepared from citric acid and sodium bicarbonate and can realize controlled release of carbon dioxide due to water migration in high-moisture grains; after the grains are harvested, the high-moisture grains which are not subjected to water removal treatment are used before being loaded to a vehicle or a ship; the grains are packaged by non-woven cloth or ventilating gauze or a multi-layer hemp cloth bag and are uniformly placed at the bottom of the loading vehicle or the ship. The method is executed according to the dispersion characteristic of carbon dioxide in a grain stack; the carbon dioxide controlled-release agent and the carrier are placed at the bottom of the grain stack, so that inner air flow circulation is realized before the grain stack does not generate heat obviously and the mildewing does not cause obvious damage to the quality of the stored grains; therefore, heat exchange between an inner environment and an outer environment is realized, and the mildewing is prevented.

Description

[0001] technical field [0002] The invention belongs to the technical field of grain logistics safety, and specifically relates to a method for suppressing mildew in the process of high-moisture grain loading logistics through slow release and circulation of carbon dioxide. Background technique [0003] my country's grain output is huge, the grain harvest is seasonal, and the drying equipment in the grain production area is scarce. In addition, the grain quality is affected by external environmental factors, and the circulation process is prone to deterioration. Therefore, it is necessary to carry out quality management and control technology in the circulation process. matching. The high water content and high water activity of grain, together with the heat generated by the grain, can easily cause a large number of microorganisms in it to multiply, which will eventually lead to mildew and quality deterioration of the grain, and lose its edible value. High-moisture grains r...
