Abstract
The invention discloses a method for preparing a sweet potato residue feed. The method comprises the following steps of: (1) crushing crop straws into granules of 10 to 60 meshes to obtain crop straw powder; (2) mixing the crop straw powder obtained in the step (1) and a sweet potato starch processing residual product in a ratio of 1: (1.5-3) to obtain a sweet potato residue feed raw material, wherein the sweet potato starch processing residual product is sweet potato residue and/or protein waste water; and (3) filling the sweet potato residue feed raw material obtained in the step (2) into a sealed container, compacting and sealing, and storing for 7 to 28 days at normal temperature to obtain the sweet potato residue feed. The technical scheme provided by the invention has the following advantages that: (1) the treatment process is simple, convenient and easy to implement; (2) no waste is discharged in the whole processing process which is a process of fully utilizing the sweet potato residue, the protein waste water and the crop straw powder; and (3) the crude protein content of the feed can reach 4.5 to 8.2 percent, and the starch content of the feed can reach 9.8 to 33 percent (dry basis, dried but not fermented).
Description
Technical field
The present invention relates to a kind of preparation method of feed, be specifically related to the preparation method of a potato seed dreg fodder.
Background technology
Produce a large amount of wet potato slag and waste water in the potato starch processing, contain organic matters such as amounts of protein, polysaccharide in these accessory substances.The potato slag contains organic matters such as a large amount of pectin, protein, starch, and viscosity is high, and retention ability is strong, squeezing and drying and dehydrating difficulty, and the COD value of deviating from water is also than higher.At present, wet potato slag main methods is to dry behind the direct press dewatering, but dewatering efficiency is low, and rate of drying is slow, and energy consumption is high.Organic nutrient substance content is high in the albumen water, directly the exhaust emission environment.Though existing processing method can realize qualified discharge, equipment and operating cost are high, are difficult to drop into practical application, and also there is secondary pollution in some, has influenced the sustainable development of surrounding environment and potato starch processing industry.
Summary of the invention
The object of the invention is exactly to above-mentioned defective of the prior art, provides a kind of crop material powder that utilizes to absorb the method that the organic nutrient substance that adsorbs in potato slag and the proteinic wastewater prepares feed.
To achieve these goals, technical scheme provided by the invention is: the preparation method of a potato seed dreg fodder, and said preparation method may further comprise the steps:
1) agricultural crop straw is broken, the particle after the fragmentation is the 10-60 order, obtains the agricultural crop straw powder;
2) the agricultural crop straw powder that step 1) is obtained, according to weight ratio agricultural crop straw powder: potato starch processing resultant product is that 1:1.5-3 mixes, and obtains potato dreg fodder raw material; Said potato starch processing resultant product is potato slag and/or proteinic wastewater;
3) with step 2) the potato dreg fodder raw material that the obtains airtight container of packing into carries out the compacting sealing, after storage at normal temperature 7-28 days, promptly obtains the potato dreg fodder.
Agricultural crop straw in the said step 1) is maize straw, wheat stalk, rape stalk, flax stalk and/or legume crop stalk.
In the said step 1), the crushed particles of agricultural crop straw is 20 orders.
Said step 2) in, according to weight ratio agricultural crop straw powder: potato starch processing resultant product is 1:2.
In the said step 3), storage at normal temperature 14 days promptly obtains the potato dreg fodder.
Beneficial effect of the present invention is:
The present invention is to be raw material with potato slag and proteinic wastewater in the potato starch processing, serves as the absorption absorption carrier with crop straw such as the corn of fragmentation, wheat, rape, flax, beans, is sealed to form according to compacting after certain mixed to be feed.Not only can reclaim organic nutrient substances such as starch in potato slag and the albumen water, protein, polysaccharide easily; Feed is provided; And solved that the potato slag is difficult to utilization with waste water in the processing of potato starch such as potato; Random discharging, with serious pollution problem, overall process do not have discarded discharging, have improved the utilization rate and the biological value of crop material simultaneously yet.The present invention has following advantage:
(1) processing procedure is easy to be easy to implement;
(2) the not discarded discharging of entire process process is the process with potato slag, proteinic wastewater and crop material powder complete utilization;
(3) crude protein content of this feed can reach 4.5-8.2 %, and content of starch can reach 9.8-33% (butt, dry azymic).
