Embodiment Construction

[0017] Such as figure 1 Shown, technique of the present invention is:

[0018] First, through screening the straw, dry the straw straw without mildew and no qualitative change, and crush it into grass powder with a grass powder grinder, and the number of crushed mesh is 60 mesh;

[0019] Second, the determination of urea toxicity: pulverize urea particles with a pulverizer, evenly sprinkle them in the pulverized grass powder, and stir to make the final concentration of urea be about 1%, and the final concentration of urea should not exceed 3% of the total weight. These grass powders were first fed to 50 bred cows, and 18 blood indicators were measured through blood index analysis, and no abnormalities were found in the results. Then these grass powders were fed to 30 cows, and 18 blood indicators were measured, and no abnormalities were found. These experiments proved that the urea added in the grass powder produced did not cause adverse effects on the cows;

[0020] Thirdly...

Abstract

The invention discloses a rice straw particle making technology. The technology is characterized in that the technology comprises the following steps: 1, crushing dry non-moldy unmetamorphosed rice straws through a grass meal crusher to form 60 mesh straw powder; 2, uniformly scattering urea in the straw powder until the final urea concentration of 1-3%; 3, bonding the straw powder obtained in step 2 by using a gelatin solution with a final concentration of 0.5%; 4, granulating the straw powder obtained in step 3 by a granulator to form straw particles with the diameter of 3mm and the water content of 16-17%; 5, placing the particles in a room, ventilating, and stirring for heat dissipation to room temperature; and 6, weighing the straw particles, and packaging.

Description

technical field [0001] The invention relates to a production process of rice straw grass granules. Background technique [0002] Guiyang City is located in a plateau mountainous area, with karst landforms, no plains, no large-scale grazing land, small arable land per capita, insufficient feed and pasture resources; warm climate, high air humidity (annual average air relative humidity is above 80%), and the incidence of dairy cows High; the scale of milk processing is small, the processing technology is relatively backward, and the product market competitiveness is weak, which restricts the development of the city's dairy industry. However, by 2012, there were about 40,000 dairy cows in the city, and the total annual dairy cow breeding needs more than 1 million tons of pasture or silage, and it is necessary to build 300,000 mu of artificial grassland to ensure the supply of pasture for dairy cows. Our city is located in karst mountains, with bare rocks, shallow soil, no gras...
