Embodiment approach

[0100] According to a preferred embodiment of the present invention, the impurity removal device further includes at least one screen, the screen is located in the delivery pipeline 110 and the plane where the screen is located is perpendicular to the longitudinal direction of the delivery pipeline 110 . Therefore, when the raw material with large particle size is conveyed in the conveying pipeline 110 , impurities doped in the raw material with large particle size can be removed through the screen.

[0101] One sieve can also be provided, preferably a plurality of sieves, so as to give full play to the function of the sieve to remove foreign matter. The screen can be installed in the delivery pipe 110 in various ways, for example, the screen can be fixed (such as welding, snap fit, etc.) on the inner surface of the side wall of the delivery pipe 110 .

[0102] But, in order to be able to clean up the sundries remaining on the sieve in time, to keep the patency of delivery pi...

Embodiment 1

[0128] This example is used to illustrate the fermentation unit of the present invention and its usage method.

[0129] use Figure 15 The fermentation unit shown produces ethanol. The fermentation unit includes a flash tower 210, a heat source 220, an enzymolysis tank 230, a material source 240, a vacuum pump 250, a fermenter 260 and a condenser 280, and the flash tower 210 includes a first interface 211, a second interface 212, The third interface 213 and the discharge port 214, the material source 240 is communicated with the flash tower 210 through the first port 211, the enzymolysis tank 230 is communicated with the discharge port of the flash tower 210, and the vacuum pump 250 is connected with the second port of the flash tower 210. The interface 212 communicates, the fermenter 260 communicates with the enzymolysis tank 230, the condenser 280 communicates with the top of the flash tower 210, and the heat source 220 communicates with the third interface 213 of the flash...

Abstract

The invention provides a system for preparing ethanol. The ethanol preparation system comprises a potato crushing unit, a slurry preparation device and a fermentation unit. The slurry preparation device utilizes crushed products provided by the potato crushing unit to prepare slurry, and the slurry is provided for the fermentation unit. The potato crushing unit comprises a crushing device and a sedimentation tank. The crushing device and the sedimentation tank are connected to the slurry preparation device for preparing slurry. The fermentation unit comprises a communicating device communicating with an interface of a flash tower. According to the fermentation unit provided by the invention, with the potato crushing unit, continuous sand removing and impurity removing can be carried out when the potatoes are crushed. With the fermentation unit, a pipeline obstruction problem is avoided, and enzymolysis efficiency and fermentation efficiency are substantially improved. Therefore, continuous production of ethanol can be ensured.

Description

technical field [0001] The present invention relates to a system for producing ethanol. Background technique [0002] In various occasions of industrial application, the preparation of slurry is often required. For example, in a factory producing ethanol, the usual process is: first, the raw materials (such as block, flake or granular cassava, sweet potato, potato, etc.) Larger raw materials are crushed into smaller or finer raw materials, and then water and finer raw materials are mixed through a pulping device to form a slurry, and then the obtained slurry is subjected to enzymatic hydrolysis and fermentation treatment, and finally ethanol is obtained . [0003] In this traditional process, the conveyed raw materials are inevitably mixed with impurities, such as finer sand, larger stones, or plastic products such as strips of plastic cloth or woven bags. residues. Moreover, the raw materials cannot be thoroughly cleaned before entering the processing process, especiall...
