Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings.

[0030] figure 1 Shown is the process flow diagram of the existing tapioca starch production technology; as can be seen from the figure, the process flow of the existing tapioca starch production technology is usually: cassava→washing and peeling with a drum dry cleaning machine and agitating washing machine→using two-stage pulverization The crushed cassava dregs pulp is separated and extracted with a three-stage screening machine → the pulp part is dehydrated and dried by a fine slag screening machine and a two-stage disc separator scraper centrifuge → starch, and then screened and packaged as a finished product . Among them, "separation of crushed cassava residue pulp with three-stage screening machine" generally adopts vertical screening machine. The minimum motor in each vertical screening machine is 15KW. A large amount of water can be injected to dilute and dec...

Abstract

The invention discloses a production method of cassava starch. The production method comprises the steps of: washing and peeling cassava, crushing, dewatering and drying. The production method is characterized by also comprising a first-stage filter-pressing rough screening step, or a second-stage filter-pressing rough screening step, a third-stage filter-pressing rough screening step, first-stage to third-stage filter-pressing rough screening steps and first-stage and third-stage filter-pressing rough screening steps. According to the filter-pressing rough screening steps, the crushed cassava is subjected to filter-pressing by adopting a belt-type filter press, and starch slurry and manioc waste are separated out. The belt-type filter press is an efficient energy-saving belt type filter press. According to the production method, electric energy and water volume are consumed in the existing production method of the cassava starch, great links are reconstructed, the power of a motor is fully utilized, the water consumption is only 1 / 3 that of a vertical screening machine, and the filter-pressing slurry discharging speed of the efficient energy-saving belt-type filter press is 3 times that of the vertical screening machine. A large quantity of electric energy and water are saved, the environment is effectively protected, and the productivity of the cassava starch is increased.

Description

technical field [0001] The invention relates to a method for processing agricultural products, in particular to a method for processing cassava into starch. Background technique [0002] Tapioca starch is a white powder obtained by dehydration and drying of cassava after starch extraction. It is widely used in food industry and non-food industry. In my country, Guangxi is the main producing area of ​​cassava, which is generally processed into starch. The existing methods for processing cassava into starch are generally: cassava→washing and peeling→grinding→slurry separation and extraction of starch→dehydration and drying→starch; The cassava is subjected to three-stage coarse screening to obtain the pulp containing a large amount of starch, and then the pulp containing a large amount of starch is screened by a fine slag screening machine before being dehydrated and dried to become starch. [0003] In the three-stage coarse screening of the crushed cassava with a vertical sc...
