Embodiment 1

[0014] Add 134kg into a 300L jacketed coating pot with stirring device, start stirring, heat to 70°C to melt the monostearic acid, slowly add oregano oil mixed uniformly in an ordinary mixer at 1:1 (weight ratio) Mix 66 kg of heartwood with silica powder (120-130 mesh), stir and mix for 5-8 minutes, pour into a cooling tray and cool to room temperature. The prepared solid matter is pulverized into a 40-80 mesh powdered oregano oil microcapsule product in a pulverizer. The yield of the product is more than or equal to 98%, and the oregano oil content in the product is 16.5%.

Embodiment 2

[0016] Add 99kg of calcium stearate into a 300L jacketed coating pot with a stirring device, start stirring, heat to 70°C to melt the calcium stearate, add slowly and mix evenly in an ordinary mixer at 1:1 (weight ratio) 66 kg of heartwood made of oregano oil and silica powder (120-130 mesh), stirred and mixed for 5-8 minutes, poured into a cooling tray and cooled to room temperature. The prepared solid matter is pulverized into a 40-80 mesh powdered oregano oil microcapsule product in a pulverizer. The yield of the product is more than or equal to 98%, and the oregano oil content in the product is 20.8%.

Embodiment 3

[0018] Add 66kg beef tallow into a 300L jacketed coating pan with a stirring device, start stirring, heat to 70°C to melt the beef tallow, slowly add oregano oil and two 66 kg of heartwood made of silicon oxide powder (120-130 mesh) was stirred and mixed for 5-8 minutes, then poured into a cooling tray and cooled to room temperature. The prepared solid matter is pulverized into a 40-80 mesh powdered oregano oil microcapsule product in a pulverizer. The yield of the product is more than or equal to 98%, and the oregano oil content in the product is 24.6%.

Abstract

An origanum herb oil softgel as antibacterial agent for feed is prepared from origanum herb oil extracted from origanum herb, stearic acid as well material and SiO2 particles as adsorbent through fusing and cooling.

Description

1. Technical field [0001] The invention relates to a preparation process of oregano oil microcapsule powder, a natural antibacterial agent for animals, and belongs to the field of animal medicine-antibacterial medicine manufacturing. 2. Background technology [0002] Natural feed antibacterial agent oregano oil is an active substance with antibacterial effect extracted from the Chinese herbal medicine oregano, and is mainly used to treat such diseases as diarrhea, enteritis, and diarrhea. The in vitro bactericidal and bacteriostatic tests showed that oregano extracts were effective against 31 common enteritis-causing bacteria such as Gram-positive bacteria and Gram-negative bacteria, Salmonella, E. and other 100 strains of Shigella all had significant bactericidal and bacteriostatic effects. Because of its broad-spectrum antibacterial properties, safety, and extremely low residues in animals, it is used to promote the growth of chickens and pigs, prevent and treat diarrhea ...
