Embodiment 1

[0033] The preparation method of a kind of crop stalk feed of the present invention comprises the following steps: step 1, cuts the crop stalk to 3cm, puts into the pressure-resistant reactor, such as Figure 1-4 As shown, the pressure-resistant reactor has a discharge port, the discharge port is provided with a discharge valve 18, and the discharge port is communicated with the friction pipe 21, and the inner wall of the friction pipe 21 is evenly ringed with a plurality of Sharp protrusions 22, wherein the discharge valve 18 is closed before the crop stalks are put into the pressure-resistant reactor;

[0034] Wherein, the moisture content of the crop straw is 12%, which is a mixture of corn straw, wheat straw, rice straw, cotton straw, soybean straw, sesame stalk, sunflower stalk and rape straw.

[0035] Step 2: Introduce saturated water vapor into the pressure-resistant reactor, and carry out two high-temperature and high-pressure reactions in succession, among which, pres...

Embodiment 2

[0044] A method for preparing crop straw feed of the present invention comprises the following steps: step 1, cutting the crop straw to 7 cm, and putting it into a pressure-resistant reaction kettle, such as Figure 1-4 As shown, the pressure-resistant reactor has a discharge port, the discharge port is provided with a discharge valve 18, and the discharge port is communicated with the friction pipe 21, and the inner wall of the friction pipe 21 is evenly ringed with a plurality of Sharp protrusions 22, wherein the discharge valve 18 is closed before the crop stalks are put into the pressure-resistant reactor;

[0045] Among them, the moisture content of the crop straw is 38%, which is a mixture of corn straw, wheat straw, rice straw, cotton straw, soybean straw, sesame stalk, sunflower stalk and rapeseed straw.

[0046] Step 2. Pass saturated water vapor into the pressure-resistant reactor, and carry out two consecutive high-temperature and high-pressure reactions. Among them...

Embodiment 3

[0055] A method for preparing crop straw feed of the present invention comprises the following steps: step 1, cutting the crop straw to 10 cm, and putting it into a pressure-resistant reaction kettle, such as Figure 1-4 As shown, the pressure-resistant reactor has a discharge port, the discharge port is provided with a discharge valve 18, and the discharge port is communicated with the friction pipe 21, and the inner wall of the friction pipe 21 is evenly ringed with a plurality of Sharp protrusions 22, wherein the discharge valve 18 is closed before the crop stalks are put into the pressure-resistant reactor;

Abstract

The invention discloses a preparation method of a crop straw feed. The method comprises the following steps: firstly chopping crop straw into segments 3-10 centimeters long, and placing the segments in an overpressure-resistant reaction kettle, wherein the overpressure-resistant reaction kettle is equipped with a discharge port, and the discharge port is equipped with a blowdown valve, and the discharge port communicates with a friction tube, and the inner wall of the friction tube is uniformly and circularly equipped with a plurality of pointed bulges; introducing saturated water steam into the overpressure-resistant reaction kettle, pressurizing the reaction kettle to 8-12 kg / cm<2>, controlling and maintaining a temperature of 130-160 DEG C for 5-10 minutes, re-pressurizing the reaction kettle to 12-24 kg / cm<2>, and controlling and maintaining a temperature of 150-220 DEG C for 2-10 minutes; and finally opening the blowdown valve for ejecting the crop straw through the friction tube so as to obtain feed products. The method carries out effective improvement on the straw, improves straw digestibility, and greatly increases the comprehensive efficiency of turning straws into feed.

Description

technical field [0001] The invention relates to straw forage for animal husbandry, in particular to a preparation method of crop straw forage. Background technique [0002] my country is a large agricultural country with abundant crop straw resources, the total amount of which is the largest in the world, accounting for 20% to 30% of the world's total straw production. The annual output of crop straw is about 900 million tons, which is about 50% of the grassland mowing amount in northern my country. times. At present, the utilization rate of straw is very low, and straw burning is under great pressure to destroy the ecological environment. The invention can realize the utilization of straw resources as feed, not only can effectively solve the problem of straw burning, but also can turn waste into wealth and promote the development of the cattle and sheep industry. [0003] At present, my country's dairy cattle, beef cattle, and mutton sheep require a serious shortage of hig...
