Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing.

[0020] A method of crushing fine powder of whole rice for fuel ethanol production, such as figure 1 As shown, the process description: the whole rice 1 is sent to the pulverizer 3 through the conveying system 2, and the fine powder after the crushing of the whole rice is conveyed and separated by the negative pressure conveying system 4, and the fine powder enters the fine powder drum sieve for screening 5, and the undersize is Qualified fine powder 6 enters the mixing system 7 to mix the material and adjust the slurry, the slurry is sent to process 8, the fine powder enters the fine powder drum sieve and sieves 5, and the oversize is flake rice husk 9 returns to the pulverizer 3 for re-grinding.

Abstract

The invention discloses a method for crushing fine powders of whole rice for fuel ethanol production. The method is characterized in that rice (1) is fed into a pulverizer (3) through a conveying system (2), the crushed fine powder is conveyed and separated by a negative pressure conveying system (4), the fine powder enters a fine powder drum screen (5) for screening, undersize products are qualified fine powders (6) and enter a stirring system (7) for stirring and mixing, the slurry is sent to a next procedure (8), the fine powders enter the fine powder drum screen (5) to be sieved, the oversize products are flaky rice hulls, and the flaky rice hulls (9) are re-crushed by the pulverizer (3). The method has the beneficial effects that the problems that the rice with hulls is crushed and the fine powders are mixed with strip rice hulls are solved, the crushed rice fine powder reaches the control range of qualified particle size, the production process requirements are met, the method isapplied to the fuel ethanol in rice production and the effect is good.

Description

technical field [0001] The invention belongs to the technical field of fuel ethanol production, in particular to a method for pulverizing whole rice fine powder for fuel ethanol production. Background technique [0002] Raw materials for fuel ethanol production mainly include cassava, corn, and old rice. [0003] In the traditional process, rice is used as raw material for the production of fuel ethanol. The rice is dehulled into brown rice and rice husk, and the rice husk is crushed and used as a low-value feed filler. Fuel ethanol is produced, and the waste mash produced is processed to produce by-product feed and biogas. [0004] In the existing technology, rice is used as a raw material for the production of fuel ethanol. The rice is directly crushed into a fine powder with a certain particle size without husking, and fuel ethanol is produced through liquefaction, fermentation, and rectification, and by-product feed and biogas are produced after waste mash is processed...
