Embodiment 1

[0009] Example 1: Refer to the attached figure 1 . A medicinal nano crystallization tank, which includes a crystallization tank. The wall of the crystallization tank body 1 is an interlayer wall 10. The interlayer wall 10 is provided with a fluid inlet and a fluid outlet and forms a loop with a subcooled air refrigerator 5. The wall surface is uneven and rough, and the uneven rough surface is provided with a nano layer, and the surface of the nano layer is uneven; the inner wall of the sandwich has uneven rough surface and the uneven nano layer on the uneven rough surface. The manufacturing process is existing The technology is not described here. The crystallization tank 1 is provided with a subcooling agitator 2, the shaft and U-shaped stirring teeth of the agitator are in a hollow tubular structure and are fixed on the upper part of the crystallization tank 1 by a bearing positioning frame, and are driven to rotate by a motor 1. The hollow pipe stirring shaft 4 is connecte...

Embodiment 2

[0010] Embodiment 2: On the basis of embodiment 1, a non-adhesive pneumatic crystallization method for medicinal nano crystallization tanks. First, the temperature controller 7 sets the required crystallization temperature of the material, and then the temperature controller 7 commands The cold air cooler 5 cools the air drawn by the exhaust fan. Since the material is in a non-adhesive fit with the 1 nanometer inner wall surface of the crystallization tank, the subcooled air cooler 5 passes through the cold air conveying pipe to the hollow tube stirring shaft 4 and the interlayer at the same time The multiple air-cooled pipes on the wall 10 and the inner wall of the sandwich wall pressurize and convey the supercooled cold air. One is to force the temperature in the crystallization tank 1 to drop sharply. At the same time, the multiple air-cooled pipes and hollow U-shaped stirring teeth on the inner wall of the sandwich wall Multiple sub-cooled air discharge blow holes on the hor...

Abstract

The invention relates to a medical nanometer crystallizing tank and a crystallization method thereof. The medical nanometer crystallizing tank can cause condensed medicine to quickly crystallize in air drive, and comprises a crystallizing tank, wherein the body wall of the crystallizing tank is an interlayer wall; the interlayer wall is provided with a fluid inlet and a fluid outlet and forms a loop with a cold air refrigerator; the inner wall surface of the interlayer is a rugged roughened surface provided with a nanometer layer; the surface of the nanometer layer is a rugged surface; the crystallizing tank is provided with a supercooling stirrer; the shaft of the heating stirrer and a U-shaped stirring tooth are in hollow tubular structure and are fixed on the upper part of the crystallizing tank body by a bearing locating rack; and a hollow pipe stirring shaft is connected with the outlet of a upercooling air refrigerator via a cold air conveying pipe. The medical nanometer crystallizing tank has the advantages that medicine material and the inner wall surface of the crystallizing tank body can be prevented from sticking. In addition, the purpose of quickly crystallizing in the air drive dynamics can be realized, and crystallization efficiency is high.

Description

Technical field [0001] The invention relates to a medicinal nano crystal crystallization tank and a crystallization method which can make concentrated medicine not stick to the inner wall of a tank, and can quickly crystallize the concentrated medicine in the wind, and belong to the field of crystal tank manufacturing. Background technique [0002] Crystallization tank is a crystallization equipment that requires chilled water or refrigerant water to cool down rapidly after the material is mixed and reacted. The key link is the size of the interlayer, the structure of the agitator and the material outlet form, high-precision polishing in the tank, and cleaning in the tank. There is no dead angle requirement to meet the process conditions. The company has rich design and manufacturing experience for different process requirements, and the equipment produced fully meets the requirements of GMP verification. Can produce 0.3-5m3 crystallization tank. Its shortcomings: First, the ma...
