Embodiment 1

[0025] The present embodiment provides a kind of two-stage process to produce the method for spraying corn bran, and this method is carried out according to the following steps:

[0026] Step 1: Dry the corn fiber at 75°C for 30min-40min by means of tube bundle drying, so that the water content in the dried corn fiber is 8%-12%, and then add it to the dried corn fiber according to "per ton of dried corn fiber Add 0.7 tons of corn steep liquor to the corn fiber, add corn steep liquor, mix well, and then dry the corn fiber at 75°C for 30min-40min to a moisture content of 8%-12% by tube bundle drying to obtain pre-slurry Corn fiber; wherein: the solid content of corn steep liquor is 42%;

[0027] Step 2: the pre-slurried corn fiber obtained in step 1 is pulverized to below 3mm, and passes through a sieve of φ3 (the diameter of the sieve opening is 3mm), so as to obtain pulverized corn fiber, which is added to the pulverized corn fiber according to "per ton of pulverized corn fibe...

Embodiment 2

[0031] The present embodiment provides a kind of two-stage process to produce the method for spraying corn bran, and this method is carried out according to the following steps:

[0032] Step 1: Dry the corn fiber at 93°C for 30min-40min by means of tube bundle drying, so that the water content in the dried corn fiber is 8%-12%, and then add it to the dried corn fiber according to the "per ton of dried corn fiber Add 0.8 tons of corn steep liquor to the corn fiber, add corn steep liquor, mix well, and then dry the corn fiber at 75°C for 30min-40min to a water content of 8%-12% by tube bundle drying to obtain pre-slurry Corn fiber; wherein: the solid content in the corn steep liquor is 42%; the protein content in the pre-slurried corn fiber obtained in step 1 is 19.5%;

[0033] Step 2: crush the pre-slurred corn fiber obtained in step 1 to below 3mm, and pass through a sieve of φ3 (the diameter of the sieve hole is 3mm) to obtain the crushed corn fiber. Add 0.35 tons of corn s...

Embodiment 3

[0037] The present embodiment provides a kind of two-stage process to produce the method for spraying corn bran, and this method is carried out according to the following steps:

[0038] Step 1: Dry the corn fiber at 93°C for 30min-40min by means of tube bundle drying, so that the water content in the dried corn fiber is 8%-12%, and then add it to the dried corn fiber according to the "per ton of dried Add 0.75 tons of corn steep liquor to the corn fiber, add corn steep liquor, mix well, and then dry the corn fiber at 75°C for 30min-40min to a water content of 8%-12% by tube bundle drying to obtain pre-slurry Corn fiber; wherein: the solid content in the corn steep liquor is 42%; the protein content in the pre-slurried corn fiber obtained in step 1 is 19.5%;

[0039] Step 2: the pre-slurried corn fiber obtained in step 1 is pulverized to below 3mm, and passes through a sieve of φ3 (the diameter of the sieve opening is 3mm), so as to obtain pulverized corn fiber, which is added...

Abstract

The invention discloses a method for producing corn husks sprayed with corn steep liquor through a two-stage technology, and belongs to the technical field of processing of corn starch by-products. The method comprises the following steps of drying corn fibers through tube bundle drying until the water content is 8%-12%, adding corn steep liquor to the dried corn fibers, drying the corn fibers through tube bundle drying once again until the water content is 8%-12%, to obtain corn fibers with corn steep liquor addition in advance, performing crushing and screening, adding the corn steep liquoronce again, and performing uniform mixing so as to obtain corn fibers with corn steep liquor addition; and performing airflow drying on the corn fibers with corn steep liquor addition, so that the water content of the corn fibers with corn steep liquor addition, after the airflow drying, is reduced to 8%-12% and the corn husks sprayed with the corn steep liquor can be obtained. According to the method disclosed by the invention, the problem of low protein content caused by product color differences and low corn steep liquor addition quantity can be solved; the products prepared by the method are uniform and consistent in color and free of color differences; and besides, the corn steep liquor addition quantity and the protein content of the products are notably increased than those througha traditional technology, and the corn husks sprayed with the corn steep liquor are suitable for being used as a feed.

Description

technical field [0001] The invention relates to a method for producing sprayed corn husks by a two-stage process, and belongs to the technical field of corn starch by-product processing. Background technique [0002] Corn fiber and corn steep liquor are common by-products in the process of corn starch processing. Corn fiber and corn steep liquor can be mixed and dried together to obtain sprayed corn bran, which is rich in protein and is a good protein feed. Sprayed corn husk is a feed obtained by mixing and drying soaked corn steep liquor and crushed corn fiber. Since the protein contained in sprayed corn husk has become a new protein feed material widely used by feed manufacturers at home and abroad, It is usually used to replace soybean meal and fish meal in livestock and poultry and aquatic compound feed, and can be directly fed to ruminants. [0003] The traditional spraying corn husk production process is to use two-stage or multi-stage tube bundle dryers to dry the co...
