Embodiment 1

[0062] Dig a ground pool such as 20m long, 10m wide and 10m deep on the ground (such as Figure II ), use reinforced concrete to build the bottom of the pool and the walls of the pool. The filtrate tank is pre-built at the bottom of the pool, and the filtrate tank cannot be blocked by straw bales. The infusion tube is preset in the tank and leads from the wall of the pool. Inject fluid into the reservoir from outside the reservoir. One wall of the pool wall is provided with a sleeve for connecting the temperature sensing probe. The sleeve has a connection line for the temperature sensing probe, and the liquid can be drawn out from the pool or injected from the outside of the pool. The four walls of the pool are 50-100cm above the ground. Epoxy resin is used for the anti-corrosion and anti-leakage treatment of the pool wall, bottom and pool interior. The inner volume of the pool is about 1900m 3 .

[0063] A closed valve is provided at the outlet of the filtrate infusion t...

[0100] It can be seen from Table 2-2 that the fresh corn stalks after maturity still contain a large amount of fermentable sugars, but after the fresh corn stalks are cut and dried naturally or matured and air-dried in the field, a large amount of fermentable sugars will be lost . After 100kg of fresh straw is dried, only 45-55kg of dry straw will be obtained. The chemical composition of this dry stalk is as table 2-3

Embodiment 3

[0125] 1. Preservation material: sugar cane.

[0126] The method provided by the invention is also applicable to the preservation of fermentable sugar in sugarcane stalks, so as to improve the economic benefit of producing ethanol from sugarcane.

[0127] 2. Save the pool library.

[0128] In this example, a cylindrical pool is used, and a ground pool with a diameter of 20m is dug underground, and the pool wall and bottom are tightly paved (welded) with 10mm thick plastic plates. The filtrate tank is pre-built at the bottom of the pool, and the filtrate tank cannot be blocked by straw bales. The infusion tube is preset in the tank and leads from the wall of the pool. Inject fluid into the reservoir from outside the reservoir. One wall of the pool wall is provided with a sleeve for connecting the temperature sensing probe. The sleeve has a connection line for the temperature sensing probe, and the liquid can be drawn out from the pool or injected from the outside of the pool....

Abstract

The invention provides a method for preserving the straw of beet, sweet potato, potato, cassava, turmeric and other tuber crops. It also provides the usage of the preserved straw to produce ethanol. The said method comprises following steps: disintegrating the straw into segments of less than 20 cm and disinfecting them; putting the segments into pool and spraying a layer of salt on the surface; adding acid solution of 2%-20% into the pool, the adding amount is 5-30% of the total straw weight; sealing the pool; keeping the temperature of pool be below 35 Deg. C. The method can not only keep the straw for a long time and produce ethanol for the whole year, but also increase the juice yield and fermentative sugar quantity with juice. It is proved that the juice yield amounts to above 75%, and the sugar degree of juice is above 12% after the straw is preserved for six months.

Description

technical field [0001] The invention relates to a method for preserving plant straws and the use of the preserved straws to prepare liquid fuel, in particular to a method for preserving fresh plant straws and tubers and the use of the preserved straws or tubers for preparing ethanol. technical background [0002] As an energy crop capable of producing ethanol, sweet sorghum has many advantages such as high solar conversion efficiency, high biological yield per unit area, and strong adaptability (drought, waterlogging, salt-alkali, and barren) and many other advantages. Recognized as "the most powerful competitor in the bioenergy system", it is one of the most promising biomass energy crops to realize industrialization first. The industrialization of sweet sorghum to produce biomass energy mainly uses sweet sorghum stalks to produce ethanol. The essence is first to make full use of the sugar solution (water and sugar) that accounts for more than 75...
