Problems solved by technology

[0002] The current straw treatment mainly focuses on the silage and ammoniation of corn straw, and a large amount of rice straw and wheat straw are less utilized due to their low feeding value.
Moreover, the treated corn stalks can only be used as roughage, and still need to be supplemented with grain, which cannot fundamentally solve the contradiction between the development of animal husbandry and "human and animal competition for grain".

Embodiment 1

[0022] Embodiment 1: A kind of manufacturing method of applying biological and puffing technology to prepare pellet feed with straw, characterized in that it is composed of the following steps:

[0023] ① The straw is crushed with a straw grinder, and the powder material with a length of <5 mm is sieved;

[0024] ② Mix 1000kg of rice straw powder with 20kg of urea, and act for 15 days at room temperature;

[0025] ③ Mix 1000kg of rice straw powder after urea treatment with 5g of white putrefactive fungus, and solidify for 10d at normal temperature;

[0026] ④ Mix 1000kg of the above product into 3g of straw dry storage feed starter, and biologically treat it at room temperature and in a sealed state for 45 days;

[0027] ⑤ Mix 800kg of biologically treated rice straw powder, 120kg of corn flour, 30kg of urea, 10kg of sodium chloride, and 40kg of shell powder;

[0028] ⑥Expand the above mixture into granules with a single-screw extruder;

[0029] ⑦Counter-flow cooler to cool...

Embodiment 2

[0032] A method for preparing granule feed by applying biological and puffing technology to straw is characterized in that it consists of the following steps:

[0033] ① Wheat straw is crushed with a straw crusher, and the powder material with a length of <5mm is sieved;

[0034] ② Mix 1000kg of wheat straw powder with 20kg of urea, and act for 20 days at room temperature;

[0035] ③ Mix 1000kg of wheat straw powder after urea treatment with 5g of white putrefactive fungus, and solid fermentation at normal temperature for 18 days;

[0036] ④ Mix 1000kg of the above product into 3g of straw dry storage feed starter, and biologically treat it at room temperature and in a sealed state for 60 days;

[0037] ⑤ Mix 800kg of biologically treated wheat straw powder, 120kg of sorghum flour, 30kg of urea, 10kg of sodium chloride, and 40kg of eggshell powder;

[0038] ⑥Use a twin-screw extruder to expand the above mixture into granules;

[0039] ⑦ Cool and dry the above-mentioned prod...

Abstract

A process for preparing granular feed from straw and stalk by the biological puffing technology includes such steps as treating the powdered straw and stalk with urea, pretreating with polyenzyme, biological fermenting, proportional mixing it with energy component, additive and trace elements, puffing, granulating, drying and cooling. Its apparatus and product are also disclosed.

Description

(1) Technical field: [0001] The invention relates to a feed and a feed processing method, in particular to a manufacturing method, equipment and product for preparing granular feed by using straw with biological and puffing technology. (two) background technology: [0002] The current straw treatment mainly focuses on the silage and ammoniation of corn straw, and a large amount of rice straw and wheat straw are seldom utilized due to their low feeding value. Moreover, the processed corn stalks can only be used as roughage, and still need to be supplemented with grain, which cannot fundamentally solve the contradiction between the development of animal husbandry and the "competition between humans and animals for grain". At the same time, the country produces about 600 million tons of agricultural straw every year, about 80% of which are discarded or burned, which can easily cause fires and pollute the environment. This kind of public hazard needs to be solved urgently. (3...
