Abstract

A preparation method for an ultramicro powder of a pig-strengthening powder is characterized by comprising the following steps: (1) mixing rheum officinale and thenardite in an equal weight ratio, successively passing the mixture through a 40-type pulverizer for first stage grinding, a 35-type pulverizer for second stage grinding and an ultramicro pulverizer for third stage grinding, and forming a mixed ultramicro powder of rheum officinale and thenardite; (2) successively passing dried orange peel through through the 40-type pulverizer for first stage grinding, the 35-type pulverizer for second stage grinding and the ultramicro pulverizer for third stage grinding, and forming a dried orange peel ultramicro powder; (3) successively passing sophora flavescens through the 40-type pulverizer for first stage grinding, the 35-type pulverizer for second stage grinding and the ultramicro pulverizer for third stage grinding, and forming a sophora flavescens ultramicro powder; and (4) mixing the mixed ultramicro powder of rheum officinale and thenardite, the dried orange peel ultramicro powder and the sophora flavescens ultramicro powder in ratio to form the ultramicro powder of the pig-strengthening powder. The preparation method effectively solves the problems that rheum officinale containing cellulose is hard to grind and the yield of the ultramicro powder of the pig-strengthening powder is low.

Description

technical field

[0001] The invention specifically relates to a preparation method of veterinary medicine, in particular to a preparation method of Jianzhusan superfine powder. Background technique

[0002] Jianzhusan is a veterinary drug used for digestion, stagnation and defecation of pigs. It is recorded in the second part of the "Chinese Veterinary Pharmacopoeia" in 2010. Its ingredients contain rhubarb, Xuanming powder, flavescens, and tangerine peel. Separately pulverize and then mix according to the ratio required in the second part of the "Chinese Veterinary Pharmacopoeia" 2010 Edition to make Jianzhu powder. Because rhubarb contains high plant cellulose, it is not easy to pulverize when it is ultrafine pulverized according to the existing pulverization process, so the output per unit time is too low and the production cost is increased. At the same time, the existing pulverization process is one-time superfine pulverization, that is, directly put each component into...

Examples

Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with specific examples.

[0014] The preparation method of Jianzhu powder superfine powder comprises the following steps:

[0015] (1) Mix rhubarb and xuanming powder with a weight ratio of 1:1 to form a mixture, which is in line with the ratio of rhubarb and xuanming powder in the second part of "Chinese Veterinary Pharmacopoeia" 2010 edition, and mix the rhubarb and xuanming powder The mixture undergoes primary crushing with a Type 40 pulverizer, secondary pulverization with a Type 35 pulverizer, and tertiary pulverization with a superfine pulverizer to form a mixed superfine powder of rhubarb and xuanming powder.

[0016] (2) The tangerine peel is subjected to the primary crushing of the 40-type pulverizer, the secondary pulverization of the 35-type pulverizer, and the tertiary pulverization of the superfine pulverizer to form dried tangerine peel superfine powder.

[0017] (3) Sophora fl...
