Embodiment 1

[0013] Take 100kg of paulownia flowers, crush them into coarse powder of 5-20 meshes, then add 1000kg of water to soak for 0.5 hours, heat and extract at 100°C, and extract for 1 hour, filter the medicinal liquid to obtain the first filtrate and the first filter residue Add 600kg of water and mix with the first filter residue to carry out the second extraction, the temperature is 100°C, and the extraction time is 1 hour to obtain the second filtrate and the second filter residue, merge the first filtrate and the second filtrate, and use a decompression concentration tank The medicinal solution is concentrated to obtain the paulownia flower extract feed additive extract with a relative density of 1.20. Then the extract was spray-dried in a spray drying tower, the tower inlet air temperature was 170°C, the outlet air temperature was 80°C, and the inlet air pressure was 40Mpa to obtain the Paulownia flower extract dry powder with a moisture content of 2.38%. The dry powder of the...

Embodiment 2

[0025] Take 100kg of paulownia flowers, crush them into coarse powder of 5-20 meshes, add 600kg of water to soak for 1 hour, heat and extract at a temperature of 100°C, and extract for 2 hours, filter the medicinal liquid to obtain the first filtrate and the first filter residue Add 400kg of water and mix with the first filter residue to carry out the second extraction, the temperature is 100°C, and the extraction time is 1 hour to obtain the second filtrate and the second filter residue, merge the first filtrate and the second filtrate, and use a decompression concentration tank The medicinal solution is concentrated to obtain the paulownia flower extract extract with a relative density of 1.15. The extract is then spray-dried in a spray drying tower, with an inlet air temperature of 180° C., an outlet air temperature of 85° C., and an inlet air pressure of 40 MPa to obtain a dry powder of Paulownia flower extract with a moisture content of 2.52%. Then, the dry powder of the ...

Embodiment 3

[0033] Take 100kg of paulownia flowers, crush them into coarse powder of 5-20 meshes, then add 800kg of water to soak for 0.5 hours, heat and extract at 100°C for 2 hours, filter the medicinal liquid to obtain the first filtrate and the first filter residue After adding 500kg of water and mixing with the first filter residue for the second extraction, the temperature is 100° C., and the extraction time is 1 hour to obtain the second filtrate and the second filter residue, merge the first filtrate and the second filtrate, and use a decompression concentration tank The medicinal solution is concentrated to obtain the paulownia flower extract feed additive extract with a relative density of 1.10. The extract is then spray-dried in a spray drying tower, with an inlet air temperature of 190° C., an outlet air temperature of 90° C., and an inlet air pressure of 40 MPa to obtain a dry powder of Paulownia flower extract with a moisture content of 2.45%. The dry powder of the paulownia...

Abstract

The invention aims at providing a method for preparing paulownia flower extractive feed additives, which particularly comprises the steps of preparing extractive extract, spray-drying the extractive extract and adding auxiliary materials to achieve compound to obtain the feed additives, namely smashing paulownia flower into crude powder with 5-20 meshes, adding water 4-6 times as weight as the paulownia flower, soaking for 0.5-1 hour, carrying out the first extraction, extracting for 1-2 hours at the temperature under 100 DEG C, filtering, adding water 4-6 times as weight as the paulownia flower, carrying out the second extraction, extracting for 1-2 hours at the temperature under 100 DEG C, combining liquid medicines, and concentrating the liquid medicines into the extract with relative density of 1.10-1.20; spray-drying the extract with technology conditions of the air inlet temperature of 170-190 DEG C, the air outlet temperature of 80-90 DEG C and the air inlet pressure of 40 Mpa, wherein the moisture content of dry powder of prepared extract is smaller than or equal to 5%; and mixing the extract with at least one of carries, such as silica, pine needle meal and attapulgite powder to obtain the paulownia flower extractive feed additives.

Description

Technical field: [0001] The invention relates to a paulownia flower extract feed additive, which belongs to the technical field of feed additives. Background technique: [0002] Paulownia flower is the flower of Paulownia scrophulariaceae plant, bitter in taste, cold in nature, and enters the lung meridian. Contains ursolic acid, matteucinol, β-sitosterol (V), carotene (VI) and other components, among which ursolic acid is effective against Gram-positive bacteria, Gram-negative bacteria and yeast in vitro Bacteria have a strong antibacterial effect, among them Staphylococcus aureus, Bacillus subtilis, Streptococcus pyogenes and Streptococcus parasitoids are stronger. Paulownia flower has the functions of dispelling wind and heat, clearing heat and detoxifying, clearing liver and improving eyesight. It is often used clinically for upper respiratory tract infection, bronchial pneumonia, acute tonsillitis, bacillary dysentery, acute enteritis, acute conjunctivitis, mumps, boil...
