Embodiment 1

[0036]The puffed mixed raw material of the present invention is made of pretreated corn, broken rice, soybean meal, mixed with vegetable oil according to the mass ratio of 420:400:165:15, puffed at a high temperature of 145°C, cooled and crushed owned.

[0037] The processing method of above-mentioned puffed mixed raw material, specifically carries out according to the following steps:

[0038] Step 1: Pretreatment of a single raw material: Obtain a single raw material, namely corn, broken rice, and soybean meal; remove impurities and iron from the single raw material corn, broken rice, and soybean meal, and then follow the crushing parameters of 1.2x1.2mm (crushing particle size) crushing it separately to obtain a single raw material to be prepared after pretreatment;

[0039] The second step: mixing: the single raw material corn, broken rice, soybean meal, and vegetable oil crushed in the previous step are mixed according to the mass ratio of 420:400:165:15 (about 28:27:11:...

Embodiment 2、 Embodiment 3

[0044] Same as the puffed mixed raw material of Example 1, the difference from the processing method of Example 1 lies in the difference in the number of discharge die openings and the puffing temperature.

Embodiment 4

[0046] The puffed mixed raw material of the present invention is made of pretreated corn, broken rice, soybean meal, mixed with vegetable oil according to the mass ratio of 400:380:200:20, puffed at a high temperature of 136°C, cooled and crushed owned.

[0047] The processing method of above-mentioned puffed mixed raw material, specifically carries out according to the following steps:

[0048] Step 1: Pretreatment of a single raw material: Obtain a single raw material, namely corn, broken rice, and soybean meal; remove impurities and iron from the single raw material corn, broken rice, and soybean meal, and then follow the crushing parameters of 1.2x1.2mm (crushing particle size) crushing it separately to obtain a single raw material to be prepared after pretreatment;

[0049] The second step: mixing: the single raw material corn, broken rice, soybean meal and vegetable oil crushed in the previous step are mixed according to the mass ratio of 400:380:200:20 (ie 20:19:10:1),...

Abstract

The invention discloses a puffed mixed raw material, a processing method thereof and a compound feed prepared by using the same. The puffed mixed raw material is prepared by mixing pretreated corn, broken rice and soybean meal with vegetable oil according to the mass ratio of 20-28:15-27:9-11:1, controlling the soybean meal content in the mixed raw material to be below 20% and the vegetable oil content to be below 2%, then expanding at a high temperature of 135-145 DEG C, and then conducting cooling and pulverizing. According to the puffed mixed raw material and the processing method, the high-temperature puffing technology is utilized to eliminate anti-nutritional factors in the mixed raw material, the sterilization effect is remarkable, and the puffed material is good in taste. After thepuffed mixed raw material is added, the compound feed creep feed is good in palatability and high in processing quality and can reduce the diarrhea rate of piglets and improve the growth performanceof the piglets.

Description

technical field [0001] The invention belongs to the technical field of feed processing, and in particular relates to an extruded mixed raw material, a processing method thereof and a compound feed made from the extruded mixed raw material. Background technique [0002] At present, most energy feeds in domestic piglet feed formulas are nothing more than bulk raw materials such as corn, soybean meal, and broken rice. The starch content in common corn is 72% to 78%. Corn starch is a polymer formed by the condensation of many glucose molecules, and there are a large number of crystalline regions or amorphous structures in the starch granules, which limit the utilization of starch by weaned piglets with underdeveloped amylase systems. Compared with corn, broken rice has high total starch content, relatively low non-starch polysaccharide, resistant starch and amylose content, high digestibility and good palatability. 21-day-old weaned piglets had underdeveloped organs and limite...
