Problems solved by technology

However, this feed has many problems in industrialization or marketization. First, this feed is not competitive with traditional soybean feed in terms of nutritional value and price; , resulting in short storage time and difficult marketization; third, most distiller’s grain drying processes use hot air to dry distiller’s grains, which emits odorous gases that cause air pollution

Embodiment 1

[0022] Put 100kg of raw liquid into separator I1 for separation, and separate to obtain 8kg of distiller's grains and 92kg of thin liquid, and the thin liquid enters evaporator I2 to evaporate water to obtain syrup; send distiller's grains and ethanol steam into the extractor, and extract 6 kg of distiller's grains at a temperature of 75°C Hours later, the extract and roughage were obtained. After the roughage was evaporated by the evaporator I4, about 2.94kg of nutritious feed was obtained. The protein content of the nutritious feed was 39.7% (the shelf life was 12 months); the extract was evaporated in the evaporator III5, and about 5kg of concentrated feed was obtained. Then the concentrated liquid enters the separator Ⅱ6 and stratifies at room temperature, and about 1.7kg of oil in the upper layer is separated, and the oil, ethanol vapor and sulfuric acid catalyst (8.5g) of 0.5% oil quality are carried out in the reactor for transesterification. React at a temperature of 15...

Embodiment 2

[0024] Put 100kg of raw liquid into separator Ⅰ1 for separation, and separate to obtain 8kg of distiller's grains and 92kg of thin liquid, and the thin liquid enters evaporator I2 to evaporate water to obtain syrup; send distiller's grains and ethanol steam into the extractor, and extract 7 Hours later, the extract and roughage were obtained, and the roughage was evaporated by the evaporator I4 to obtain 2.76kg of nutritious feed, and the protein content of the nutritious feed was 40.1% (the shelf life was 12 months); the extract was evaporated into the evaporator III5 to obtain 5.2kg of concentrated liquid , and then the concentrated liquid enters the separator Ⅱ6 to separate layers at room temperature, and about 1.78kg of oil in the upper layer is separated, and the oil, ethanol vapor and 0.8% oil quality NaOH catalyst (14.24g) are transesterified in the reactor, React at a temperature of 160°C for 8 hours, and then the product enters the separator III 8 and stands at room te...

Embodiment 3

[0026] Put 100kg of raw liquid into separator I1 for separation, and separate to obtain 8kg of distiller's grains and 92kg of thin liquid, and the thin liquid enters evaporator I2 to evaporate water to obtain syrup; send distiller's grains and ethanol steam into the extractor, and extract 6 kg of distiller's grains at a temperature of 90°C Hours later, the extract and roughage were obtained. After the roughage was evaporated by evaporator I4, 2.72kg of nutritious feed was obtained. The protein content of the nutritious feed was 39% (shelf life was 13 months); the extract was evaporated in evaporator III5 to obtain 5.23kg of concentrated liquid , and then the concentrated solution enters the separator II6 to separate layers at room temperature, and about 1.8kg of oil in the upper layer is separated, and the oil, ethanol vapor and 1% oil quality KOH catalyst (18g) carry out transesterification in the reactor. The reaction temperature was 170°C for 8 hours, and then the product en...

Abstract

The invention discloses a method for producing biodiesel and a feed by the use of acorn vinasse and belongs to the field of bio-energy. According to the method, biodiesel and a feed are prepared through stock solution separation, extraction process, deoiling process, transesterification and rectification process. A biodiesel finished product prepared by the method accords with the national standard. Protein content of a prepared nutrition feed is about 40%. The biodiesel and the feed are easy to store and have long shelf-life. The method provided by the invention has advantages of convenient operation, high efficiency, no pollution, low energy consumption and good product marketization.

Description

technical field [0001] The invention relates to a method for producing biodiesel and feed with acorn distiller's grains, belonging to the field of bioenergy. Background technique [0002] Recently, with the emergence of the energy crisis, the national energy strategy is positioned to accelerate the development of alternative energy, especially renewable energy, reduce dependence on oil, and encourage the development of biomass liquid fuels including fuel ethanol in the form of national legislation , the development of fuel ethanol will help to ensure my country's energy security and improve the ecological environment. [0003] There are many raw materials for the production of fuel ethanol, including starch, sugar and lignocellulose. In my country, the development of biomass energy using non-grain crops and agricultural waste as raw materials is placed at the top of the financial support. Among wild plant raw materials, Acorns can be described as an excellent biological resou...
