System and method for extracting fibers during corn starch production

Abstract

The invention discloses a system and method for extracting fibers during corn starch production. The system comprises a fiber washing trough, wherein a squeeze-drying machine is arranged below the fiber washing trough, a primary pressure curved sieve is arranged above the squeeze-drying machine, the upper end of the primary pressure curved sieve communicates with the fiber washing trough, a balance water tank is arranged below the squeeze-drying machine, a secondary trough is arranged at one side of the balance water tank, a primary sieve rear barrel is arranged below a secondary pressure curved sieve, and the upper part of the primary sieve rear barrel communicates with the primary pressure curved sieve. The system is reasonable in structural design and convenient to use. A fiber production technology is improved through repeated research and demonstration, and superfine fibers can be extracted from the fibers. The scheme has the advantages that firstly, the water content of materialsentering a fiber tube bundle drying machine can be directly reduced, the working efficiency of the squeeze-drying machine is increased, steam consumed by products is reduced, the pulp yield of cornsfor producing fibers is increased, and the added value of the products is increased; and secondly, the structures of the products can be diversified, and the superfine fibers extracted from the fibersthrough two-stage sieving can form novel low-protein products.

Description

technical field [0001] The invention relates to the technical field of corn deep processing, in particular to a fiber extraction system and method in corn starch production. Background technique [0002] To prepare starch from corn, the corn must first be soaked to loosen the starch, protein, germ, seed coat and other components in the corn to facilitate separation. After soaking the corn, the germ is extracted by a degerming mill, and then the seed coat is separated by a professional equipment needle mill. The extracted seed coat is commonly known as fiber or feed. During the fiber extraction process, due to the high-speed impact of the needle mill, a large number of ultrafine fibers will be produced. When the fiber extrusion dehydrator is used to remove the free moisture of the fiber part, after a large amount of ultrafine fibers enter the squeeze dryer, it is easy to block the filter screen of the squeeze dryer and cause the equipment to slip, resulting in wet fibers aft...
