Problems solved by technology

[0004] In view of the existing corn stalk feed which is in the consideration of nutrition and the impact on the environment, and the problems existing in the treatment of corn stalk water, the purpose of the present invention is to provide a production method of corn stalk feed, that is, the corn stalk water is evaporated Concentrate into corn syrup, mix evenly with 2-3mm particles (corn stalk powder), and dry; then put the dried material into a pulverizer for crushing, and you can get fiber feed with high egg content

Embodiment Construction

[0016] A kind of production method of corn stalk feed, the corn that concentration is 3.5Be ° is soaked in water earlier, and general displacement is 0.6m 3 / Ton (玉米) . The corn steep liquor is concentrated to a dry matter content of 40-42% by a three-effect vacuum evaporator and a protein content of 20-22%. Three-effect vacuum evaporator, the vacuum degree of each effect is controlled at: the first effect is normal pressure, the second effect is 460 mm Hg, and the third effect is 660 mm Hg; the evaporation temperature of each effect is respectively, the first effect is 98 ° C, the second effect is 75 ° C , Three-effect 53 ℃. Then crush the corn stalks and corncobs into 2-3mm particles, that is, corn stalk powder; then mix the corn stalk powder and corn steep liquor evenly at a ratio of 1:1, and then enter the tube bundle dryer for drying. The machine moisture is 40%, the outlet water is 10-12%, and the steam pressure in the tube bundle is 0.6MP a . Finally, put the dried...

Abstract

The invention relates to a process for preparing maize straw fodder, which comprises evaporating and concentrating maize immersed water into maize syrup till the dry matter content reaches 40-42% and the protein content reaches 20%-22%, disintegrating maize straw and maize core into particles, mixing maize straw powder with maize syrup by the proportion or 1:1, finally drying and disintegrating.

Description

Technical field: [0001] The invention relates to a production method of corn stalk feed. Background technique [0002] The total annual output of my country's crop corn stalks reaches more than 500 million tons. At present, livestock farmers use corn stalks as supplementary feed for cattle and sheep through acidification, alkalization, microbial fermentation or their mutual combination (composite treatment). Above-mentioned all treatment modes to corn stalk can only improve its palatability, increase feed intake, but can't satisfy the nutritional needs of the growth and development of cattle and sheep. [0003] Starch production mainly uses corn as raw material, and corn soaking is a very important step in starch production. Through soaking, a series of physical and chemical changes occur in the tissue structure of corn, creating conditions for the separation process. There are four main methods for treating corn soaking water by traditional technology: one is to evaporat...
