A kind of extraction system and extraction method of duckweed starch

Abstract

The invention discloses an extraction system of duckweed starch. The extraction system comprises a lifting device, a grinding device, a slag-slurry separation device, a precipitation device and a spin-drying device, wherein a motor is arranged at the top of the lifting device; a transmission chain is arranged in a bin; multiple groups of collection plates for collecting and lifting duckweed are arranged on the transmission chain; the motor drives the transmission chain to rotate; the slag-slurry separation device is provided with a cylinder, and a strip brush is arranged on a spindle in the cylinder; the spin-drying device is provided with a drum which is connected with a vacuum pump through a vacuum pipeline, and the water-containing starch stuck on the surface of the drum is completely pumped by the vacuum pump; and the lifting device, the grinding device, the slag-slurry separation device, the precipitation device and the spin-drying device are connected in turn. The invention also discloses an extraction method for duckweed starch. Through the invention, current blank of starch extraction technology is filled, continuous and efficient extraction of duckweed starch is facilitated after large-scale culture of duckweed, and later utilization and processing of the duckweed starch are convenient.

Description

technical field [0001] The invention relates to an efficient extraction system and extraction method of duckweed starch. Background technique [0002] The extraction of starch in plants is the basis for further processing and application of starch. my country's traditional manual extraction of starch from plants has a long history, but the efficiency of extracting starch from plants is different, and it is time-consuming and laborious. Starch contained in plants is a water-insoluble substance, and starch itself does not have fluidity, so the extraction process is very difficult and complicated. With the rapid development of society, domestic small and medium-sized enterprises that extract plant starch have put forward higher requirements in terms of quantitative production, environmental sanitation, and machine operation safety. [0003] The aquatic plant duckweed is the smallest flowering plant in the world. It is widely distributed all over the world. There are 38 specie...
