Embodiment 1

[0035] The rhizomes of calla lily are collected, washed, crushed, and then dried quickly to obtain a dry powder with a water content of 15%, which is stored for future use. Get dry powder 30kg during use, and sugar content and starch contain 43.5% altogether. Add 75kg of water to make pulp, boil for 1 hour, cool to 60°C, adjust the pH to 4.5, add 1.2 million units of glucoamylase, keep the temperature for 1 hour for hydrolysis, detoxification and saccharification, filter after cooling, and remove 32kg of slag with a water content of 45%. Obtain 66.9kg of sugar juice containing 19.5% of degraded sugar and original sugar, add 140g of Angelica alcoholic yeast, ferment for 18 hours, directly undergo conventional crude distillation and rectification, obtain 80% alcohol 8.2kg, and dehydrate to obtain 99.8% alcohol Absolute ethanol 6.08kg.

Embodiment 2

[0037] Collect fresh calla lily rhizomes, wash them, measure their water content to be 91.52%, and have a sugar content of 5%. Take 100kg, and after preliminary crushing, expose them to the sun in sunny weather to reduce the water content to 75%. The raw materials are further crushed and beaten, steamed at about 90°C for 1 hour, cooled to 60°C, adjusted to a pH of 4.5, added with 400,000 units of glucoamylase, and kept at a constant temperature for 1 hour to complete detoxification and starch saccharification. After cooling, filter to remove 45% water. Slag 10.28kg, obtained 24.1kg of sugar juice containing 16.21% of degraded sugar and original sugar, added 50g of Angelica alcohol yeast, fermented for 18 hours, directly obtained 80% alcohol 2.27kg through conventional crude distillation and rectification, Dehydration to obtain 1.78kg of 99.8% fuel ethanol.

[0038] According to the above examples, the starch in the calla lily powder is close to 43.5%, and 203 kilograms of fuel...

Abstract

The invention provides a new fuel alcohol preparation method using alocasia as raw material, comprising the following steps: preliminarily crushing and pulping, poison removing and saccharifying, fermenting, crudely distillating, rectifying and dewatering. The fuel alcohol industrial raw material is planted on the shading land of the tropical-sub tropical forest. The preparation method can large-scale prolong the raw material resource amount of the fuel alcohol, reduce the production cost of the fuel alcohol in tropical-sub tropical region, increase the production efficiency with good social and economic benefit.

Description

technical field [0001] The invention relates to a method for preparing fuel ethanol, specifically, a method for producing fuel ethanol by using calla lily as a new raw material. Background technique [0002] my country encourages the use of non-grain crop raw materials to develop fuel ethanol to ensure national food security. In the prior art, the preparation of fuel ethanol mainly uses cassava, sugarcane, sweet sorghum, sweet potato, banana, plantain and other non-grain crops as raw materials. These crops are sunshine-loving crops and can only grow on sunny land. In my country's hot-subtropical regions, forest land is the main area. For example, Hainan, Guangdong, Guangxi, Yunnan, Fujian and other provinces have more than 10 million mu of rubber forest land and tens of millions of mu of fruit forest land. Mu, the above-mentioned crops cannot be grown on this type of land. The method of preparing fuel ethanol from the above-mentioned crops obviously has great limitations in...
