Problems solved by technology

However, using a small-aperture ring die to produce small-grained poultry feed and applying it to replace conventional crushed feed in the early growth stage has not been reported and implemented in the industry. If the test is successful, the unstable quality of crushed feed can be solved. , reduce the frequency and quantity of unqualified materials returning to the machine, and also improve production efficiency to a certain extent

Embodiment 1

[0052] A method for producing small granules in the early growth period (510) of broilers, the preparation steps comprising:

[0053] Batching steps: mix ingredients accurately according to the formula;

[0054] Granulation steps: Use 420 stainless steel ring die, ￠2.0mm, compression ratio 1:5-8, granulate at 70-85°C to make the degree of gelatinization reach 90%, adjust the position of the cutter of the granulator, and control the product The length is 0.5-1.0d;

[0055] Cooling step: After granulation, the granules are cooled, and the temperature difference between the finished material temperature and room temperature is ≤5°C;

[0056] Classification steps: the upper sieve of the grading sieve is 6-10mm, and the bottom sieve of the grading sieve is 1.5-1.8mm. Start the sieve screening during the granulation process;

[0057] Finished product packaging: finished product hardness 1-2.0kg.

Embodiment 2

[0059] A method for producing crushed feed for broiler chickens in the early growth period (510), the preparation steps comprising:

[0060] Batching steps: mix the ingredients accurately according to the 510 formula;

[0061] Granulation steps: Use 420 stainless steel ring die, ￠3.0mm, compression ratio 1:5-10, granulate at 70-85°C to make the gelatinization degree reach 90%;

[0062] Cooling step: After granulation, the granules are cooled, and the temperature difference between the finished material temperature and room temperature is ≤5°C;

[0063] Crushing step: adjust the gap between the rollers of the granulator, and adjust the crushing particle size of the finished product to 1.5-3.0mm;

[0064] Classification steps: the upper sieve of the grading sieve is 3mm, and the bottom sieve of the grading sieve is 1.5-1.8mm. The sieve sieving is started during the granulation process.

[0065] Finished product packaging: finished product particle size 1.5-3.0mm.

Embodiment 3

[0067] A method for producing small pellets for broilers in the mid-growth period (511), the preparation steps of which include:

[0068] Ingredients step: Mix the ingredients accurately according to the 511 formula;

[0069] Granulation steps: Use 420 stainless steel ring die, ￠2.0mm, compression ratio 1:5-10, granulate at 70-85°C to make the degree of gelatinization reach 90%, adjust the position of the cutter of the granulator, and control the product The length is 1.0-2.0d;

[0070] Cooling step: After granulation, the granules are cooled, and the temperature difference between the finished material temperature and room temperature is ≤5°C;

[0071] Classification steps: the upper sieve of the grading sieve is 6-10mm, and the bottom sieve of the grading sieve is 1.5-1.8mm. The sieve sieving is started during the granulation process.

[0072] Finished product packaging: finished product hardness 2.0-3.0kg.

Abstract

The invention discloses a granulum fodder with the diameter of 2.0 mm, and a preparation method of the granulum fodder. The granulum fodder is 2.0 mm in diameter, 0.5-2.0 d in length, and 1-3.0 kg in rigidity. According to the invention, a 420 stainless steel ring die with the diameter of 2.0 mm and the ratio of compression of 1:(5-8) is adopted; and a 420 stainless steel ring die with the diameter of 3.0-4.5 mm and the ratio of compression of 1:(5-10) is adopted. Tests show that the scheme is feasible. According to the invention, the following advantages are achieved: the granulum fodder with the diameter smaller than 2.0 mm can completely replace crushed materials, and moreover, the product quality is more stable, and the production efficiency is improved. During the using of the granulum fodder, the food consumption and the growth effect of the broiler chicken at the early stage are not affected, the crowd uniformity can be better improved, the sick chicken amount can be reduced, and the mortality and elimination rate is also reduced, and therefore, a better cultivation benefit is brought to farmers.

Description

technical field [0001] The invention relates to small particle feed instead of crushed feed, in particular to a method for preparing small particle feed for broilers in the early and middle stages. Background technique [0002] In the production of traditional broiler feed, the feed for broiler chickens in the early growth stage (0-25 days old) cannot eat large-grained feed due to the characteristics of broiler growth stage feed intake, and crushed feed is often used, and the crushed feed is mixed After conditioning and granulating, the final powder is first made into pellets (the particle size is generally made by a ring die with a particle size of ￠3.0mm or above), and then crushed into crushed materials with suitable particle sizes according to the feeding stage. During the process of making crushed materials, A part of the undersize below the particle size standard is produced. According to the process design, this part of the undersize will often enter the granulation b...
