Problems solved by technology

This method can obtain a storage period of 1 to 2 months, but from the perspective of commercialization and application of sweet sorghum fermentation to produce ethanol, such a storage period still cannot meet the requirements of raw material supply for annual production

example 1

[0019] The sweet sorghum stalks of Liaotian No. 1 were selected as the test object and harvested in November. After harvesting, the sweet sorghum stalks were removed from the leaves, sheaths, ears and soil. Sweet sorghum stalks are crushed into particles with a size of 6 mesh or more with a kneading mill, 1000 grams of sweet sorghum stalk particles are taken, and 0.005 grams of dimethyl fumarate (purity ≥ 95%) are evenly mixed in. After drying for 2 days, the moisture content of sweet sorghum stalk particles can reach 22%.

[0020] The results of measuring the sugar content in the sweet sorghum stalk granules before and after drying respectively showed that the total sugar content in the sweet sorghum stalk granules was 542.75 mg / g (dry basis) before drying, while after drying, the sweet sorghum stalk granules The total sugar content in the rice is 510.54mg / g (dry basis), and the total sugar loss after drying is only 5.93% compared with that before drying. This shows that mix...

[0022] The sweet sorghum stalks of Liaotian No. 1 were selected as the test object and harvested in November. After harvesting, the sweet sorghum stalks were removed from the leaves, sheaths, ears and soil. Sweet sorghum stalks are pulverized into particles with a size of 6 mesh or more with a kneading mill, and 1000 grams of sweet sorghum stalk particles are taken, and 2 grams of dimethyl fumarate (purity ≥ 95%) are evenly mixed in. After drying for 2 days, the moisture content of sweet sorghum stalk particles can reach 22%.

[0023] The results of measuring the sugar content in the sweet sorghum stalk granules before and after drying respectively showed that the total sugar content in the sweet sorghum stalk granules was 542.75 mg / g (dry basis) before drying, while after drying, the sweet sorghum stalk granules The total sugar content in the rice is 549.12mg / g (dry basis), and the total sugar increases by 1.17% after drying than before drying. This shows that mixing 0.2% di...

example 3

[0025] The sweet sorghum stalks of Liaotian No. 1 were selected as the test object and harvested in November. After harvesting, the sweet sorghum stalks were removed from the leaves, sheaths, ears and soil. Sweet sorghum stalks are crushed into particles with a size above 6 mesh with a kneading grinder, 1000 grams of sweet sorghum stalk particles are taken, and 4 grams of dimethyl fumarate (purity ≥ 95%) are evenly mixed in. After drying for 2 days, the moisture content of sweet sorghum stalk particles can reach 22%.

[0026] The results of measuring the sugar content in the sweet sorghum stalk granules before and after drying respectively showed that the total sugar content in the sweet sorghum stalk granules was 542.75 mg / g (dry basis) before drying, while after drying, the sweet sorghum stalk granules The total sugar content is 537.20mg / g (dry basis), and the total sugar loss after drying is only 1.02% compared with that before drying. This shows that mixing 0.4% dimethyl ...

Abstract

The invention relates to a dry-typed long-term storage method for sweet sorghum stems and belongs to the technical field of agriculture. The storage method crashes the collected sweet sorghum stems into particles by a kneading grinder, evenly mixes dimethyl fumarate or trichloroisocyanuric hydrogen uric acid, dries and places the mixture in drying and ventilation position to carry out long-term storage. The storage method can acquire long-term and effective storage effect; by mixing dimethyl fumarate or trichloroisocyanuric hydrogen uric acid, the loss of effective sugar content of the sweet sorghum in the particles of sweet sorghum stems can be minimized in the process of drying. The storage method has the advantages of good storage effect for sweet sorghum stems, low consumption of production capacity and simple technology, which can provide annual raw material supply for the production of bio-ethanol prepared by sweet sorghum stems.

Description

technical field [0001] The invention relates to a storage method in the field of agricultural technology, in particular to a dry-type long-term storage method for sweet sorghum stalks. Background technique [0002] Sweet sorghum {Sorghum biocolor (L.) Moench} is a C4 crop with a high rate of photosynthesis, while compared with other species of sorghum, sweet sorghum has higher biological yield and sugar production. In terms of biological characteristics, the biological yield of sweet sorghum is relatively high, and the general stalk yield is 45000-75000kg / hm 2 , can also produce 3000~6000kg / hm 2 grains; strong stress resistance, generally sweet sorghum has strong drought and waterlogging resistance, and sweet sorghum also has strong salt-alkali resistance; wide adaptability, as long as the accumulated temperature above 10°C reaches 1500-2500°C, Choose the right variety, and it can be planted in general cultivated land, grassland, and light saline-alkali land. As an energy...
