Problems solved by technology

In order to effectively utilize straw, it is necessary to separate the straw skin from the inner pulp. Most of the existing methods for separating the straw skin and pulp use the method of fracturing and peeling the whole straw, which consumes manpower, and the processing loss of straw is relatively large, resulting in the utilization of straw raw materials. low rate

Embodiment Construction

[0024] Such as figure 1 As shown, a method for separating the husk and pulp of corn stalks of the present invention comprises the following steps:

[0025] Step 1: Mechanical crushing. The corn stalks are mechanically crushed, so that the stalk husk, straw leaves, and straw inner flesh are broken and separated from each other.

[0026] Straw husks are crushed into pieces by first cutting with a hob cutter or a twin-shaft crusher, and then rubbing and crushing with a disc crusher or a hammer mill, or directly using a disc crusher or a hammer mill. shape (fragments within 10cm) and debris, of which debris accounted for about 60%, straw leaves were crushed into short filaments and debris, of which short filaments accounted for about 50%, and the inner pulp was crushed into fragments (fragments above 1cm ) and debris, of which debris accounts for about 50%.

[0027] The method of first cutting and then crushing is used to mechanically crush the straw, so that the length of the ...

Abstract

The invention relates to a peel-pulp separation method of maize straw. The method comprises the following steps that step 1, the maize straw is mechanically crushed, so that straw peels, straw leavesand straw pulp are crushed and separated from one other; step 2, winnowing is performed on the straw peels, straw leaves and straw pulp which are obtained in step 1 to separate the straw pulp from thestraw leaves and the straw peels, and the straw pulp is collected; step 3, screening is conducted through a sieve, and the straw peels and the straw leaves are collected.

Description

technical field [0001] The invention relates to a method for separating the husk and pulp of corn stalks. Background technique [0002] At present, the annual production of straw in the country is about 900 million tons, and the collectable amount is 824 million tons, of which corn straw accounts for about 30% and the collectable amount is about 250 million tons. The high-value utilization of corn straw is of great significance. In order to effectively utilize straw, it is necessary to separate the straw skin from the inner pulp. Most of the existing methods for separating the straw skin and pulp use the method of fracturing and peeling the whole straw, which consumes manpower, and the processing loss of straw is relatively large, resulting in the utilization of straw raw materials. The rate is lower. Contents of the invention [0003] The purpose of the present invention is to provide a method for separating the husk and pulp of corn stalks, which can effectively save ma...
