Problems solved by technology

[0005] In the actual use of pig farms, it was found that adding pine needle powder and astragalus powder to the feed can significantly improve the growth rate of suckling piglets. However, in the actual operation process, it was found that pine needle powder and astragalus powder are easy to be affected by moisture, and it is not easy to store after unpacking , and it can only be used in a short time after each mixing, which brings great difficulties to the actual use of farmers

Embodiment 1

[0014] Crush 30kg of pine needles, pass through a 40-mesh sieve, and dry in a 70°C drying oven to about 25kg; then 50kg of astragalus is ultrafinely pulverized into a 200-mesh fine powder, and 75kg of pine needles powder and astragalus powder are mixed; add 600kg of Stir the water until it becomes thick, let stand for 1 hour, then heat and extract at a temperature of 100°C for 2 hours, then concentrate the extract to a relative density of 1.4±0.1 to obtain 100 kg of Songqi powder extract. Then add 80kg dextrin and 150kg starch, put it in the granulator and carry out bottom spray granulation, and carry out coating at the same time, the concentration of the coating agent is 5% acrylic resin solution. The process conditions are: 4 levels of air intake, 45°C inlet air temperature, 40°C outlet air temperature, 1.6bar atomization pressure, 1.0mm nozzle diameter, and 4ml / min spray speed.

Embodiment 2

[0016] Crush 50kg of pine needles, pass through a 40-mesh sieve, and dry in a 70°C drying oven to about 40kg; then ultrafinely pulverize 80kg of astragalus into 200-mesh fine powder, mix pine needles powder and astragalus powder into 120kg of pine needles powder; add 1000kg of Stir the water until it becomes thick, let it stand for 1 hour, then heat and extract at a temperature of 100°C for 2 hours, then concentrate the extract to a relative density of 1.4±0.1 to obtain 180 kg of Songqi powder extract. Then add 150kg dextrin and 220kg starch, put it in the granulator and carry out bottom spray granulation, and carry out coating at the same time. The coating agent is acrylic resin solution with a concentration of 5%. The process conditions are: 4 levels of air intake, 50°C inlet air temperature, 40°C outlet air temperature, 1.8bar atomization pressure, 1.0mm nozzle diameter, and 4ml / min spray speed.

Embodiment 3

[0018] Crush 60kg of pine needles, pass through a 40-mesh sieve, and dry in a 70°C drying oven to about 50kg; then superfinely grind 100kg of Astragalus membranaceus into a 200-mesh fine powder, mix pine needles powder and Astragalus membranaceus powder into 150kg of pine membranaceus powder; add 1200kg of Stir the water until it becomes thick, let it stand for 1 hour, then heat and extract at a temperature of 100°C for 2 hours, then concentrate the extract to a relative density of 1.4±0.1 to obtain 200 kg of Songqi powder extract. Then add 150kg dextrin and 250kg starch, put it in the granulator and carry out bottom spray granulation, and carry out coating at the same time, the concentration of the coating agent is 5% acrylic resin solution. The process conditions are as follows: 4 levels of air intake, 45°C inlet air temperature, 30°C outlet air temperature, 1.6bar atomization pressure, 1.0mm nozzle diameter, and 3ml / min spray speed.

Abstract

The invention provides a preparation method of a pine needle-radix astragali particle. Polymer is used to wrap pine needle-radix astragali powder so as to isolate pine needle-radix astragali powder from the external environment to prevent water absorption. The preparation method comprises following steps: grinding pine needles, sieving pine needle powder by a 40-mesh sieve, drying pine needle powder in a baking oven with a temperature of 70 DEG C until the weight is constant; subjecting radix astragali to ultrafine grinding to obtain fine powder with a size of 200 meshes; mixing pine needle powder and radix astragali powder according to a weight ratio of 1:2 to obtain pine needle-radix astragali powder; adding water, wherein the weight ratio of pine needle-radix astragali powder to water is 1:5-8, stirring until the solution becomes thick; allowing the solution to stand still for 1 hour, carrying out extraction for two hours under heating at a temperature of 100 DEG C, and then concentrating the extract to a relative density of 1.3-1.6 to obtain pine needle-radix astragali powder extract. The pine needle-radix astragali powder extract is coated by following steps: mixing needle-radix astragali powder extract, dextrin, and starch according to a weight ratio of 0.8-1.2: 0.5-1.0: 1.5-2.5; placing the mixture in a granulating machine, carrying out bottom-spraying to produce particles; during the granulating process, carrying out coating to obtain coated pine needle-radix astragali particles, wherein the coating agent is an acrylic resin solution with a concentration of 5%. Thegranulating-coating technology is characterized in that the air inlet level is four, the temperature of introduced air is 40 to 50 DEG C; the temperature of discharged air is 30 to 40 DEG C; the atomizing pressure is 1.6 to 1.8 bar, the diameter of the nozzle is 1.0 mm, and the liquid spraying speed is 3-4 mL / min.

Description

Technical field: [0001] The invention relates to a method for preparing Songqi powder granules, belonging to the technical field of feed additives. Background technique: [0002] Pine needles are rich in protein, amino acids, vitamins, chlorophyll, cellulose, antibiotics, sugar and various minerals and trace elements. Pine needles contain high nutritional value. As a new type of feed additive, they can be directly fed to livestock and poultry. It can obviously promote the growth and development of poultry, enhance disease resistance and improve reproductive function. [0003] Among them, the various trace elements contained in the pine needle powder have obvious effects in improving the egg production rate of poultry; the contained phytoncide and vitamins have the effect of disease prevention and disease resistance, and can effectively improve the survival rate of poultry; Contains amino acids and vitamins necessary for animal growth and development. Therefore, adding pine...
