firstly, crushing a large amount of raw materials into powder with the particle size of 3-5 mm;
step two, blending the crushed bulk raw materials by steam, then feeding the mixture into a granulating cavity, and granulating at the temperature of 90-95 ℃;
thirdly, crushing the prepared granular bulk raw materials again, adding heat-sensitive feed additives such as mineral feed, vitamins and amino acids into the crushed bulk raw materials, and stirring uniformly while adding to obtain a mixed raw material;
and step four, granulating and crushing the mixed raw materials at the temperature of 60-65 ℃ to obtain the powder-granulated granular concentrated feed.
Furthermore, the bulk raw materials are formed by mixing the anti-nutritional factors such as soybean meal, cottonseed meal, wheat and the like in equal amount.
Further, in the first step, each component in the bulk raw materials is respectively crushed until all the raw materials are crushed into powder with the particle size of 3mm, and then the powder of each component is mixed and stirred uniformly.
Furthermore, in the third step, the mineral feed, vitamins, amino acids and other heat-sensitive feed additives are added in equal amount.
Further, in the fourth step, the prepared particles are equally divided into two parts, wherein one part is crushed into powder with the particle size of 5mm at low temperature, and then the powder and the other part of particles are mixed and stirred uniformly.
After the process is adopted, the invention has the beneficial effects that: the invention provides a preparation process of a high-energy pellet concentrated feed for fattening pigs, and the produced concentrated feed has good palatability, improves feed intake, improves feed utilization rate and improves daily gain.

3. the feed-meat ratio (2.56: 1) is reduced, which is the fattening after 70 kg of body weight, and the daily gain is increased.
Example two:
the embodiment adopts the following technical scheme: the operation steps are as follows:
step one, respectively crushing each component in bulk raw materials until all the raw materials are crushed into powder with the particle size of 5mm, then mixing and uniformly stirring the powder of each component, wherein the bulk raw materials are formed by equivalently mixing anti-nutritional factors such as bean pulp, cottonseed meal, wheat and the like;
step two, blending the crushed bulk raw materials by steam, then feeding the mixture into a granulating cavity, and granulating at 95 ℃;
thirdly, crushing the prepared granular bulk raw materials again, adding thermosensitive feed additives such as mineral feed, vitamins and amino acids in equal amount into the crushed bulk raw materials, and stirring uniformly while adding to obtain a mixed raw material;
step four, granulating and crushing the mixed raw materials at 65 ℃, wherein the specific operation is as follows: dividing the prepared granules into two parts in equal amount, crushing one part into powder with the powder particle size of 5mm at low temperature, and mixing the powder with the other part of granules and stirring uniformly to obtain the granular concentrated feed with the powder added with granules.
