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 conveying pipe 110 and the plane of the screen is perpendicular to the longitudinal direction of the conveying pipe 110 . Therefore, when the large particle size raw material is transported in the conveying pipe 110, the impurities doped in the large particle size raw material can be removed through the screen.

[0101] One screen can also be provided, preferably more than one, so as to give full play to the role of the screen in removing debris. The screen can be arranged in the conveying pipe 110 in various ways. For example, the screen can be fixedly arranged (such as welding, snap fitting, etc.) on the inner surface of the side wall of the conveying pipe 110.

[0102] However, in order to be able to clean up the debris remaining on the screen in time to maintain the patency of the conveying pipe 110, preferably, suc...

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 invention relates to a system for preparing ethanol. Background technique [0002] In various occasions of industrial applications, slurry preparation is often required. For example, in a factory producing ethanol, the usual process is: firstly, the raw materials (such as cassava, sweet potato, potato, etc. in block, flake or granular form) are transported to the crushing device through a conveyor device, and then the crushing device will 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 will inevitably always be mixed with impurities, such as smaller sand, larger stones, or broken strips of plastic cloth or woven bags and other plastic products Residue...
