PL seriesmixing tank(blending tank,agitator tank) is widely used in pharmacy , fine chemical engineering and biological engineering industries. The tank body has interlayer and heat-insulating layer (for heating, cooling or heat insulating). The tank body, upper and lower closure heads( or taper ) all adopt spinning R-angle processing. The internal wallof the tank has got mirror polishing with finish Ra≤4.1μm. It has no sanitary dead corner and its wholly enclosed design ensures that materials are always mixted and ferment at no-pollution state. It is equipped with devicea including air respirator, cleaning ball,sanitation inlet, viewing mirror, and viewing lamp. The fermentation process of pharmacy, fine chemical engineering and biological products is aseptic and untainted. Fermentation tank adopts aseptic system which helps avoid microorganism pollution in the air and greatly extends quality warranty period and purity of the products. We specially designed and installed aseptic respiratory air hole or aseptic normal-pressure fermentation system, which can finish circulating heat-up and cooling. The parts that contact materials are all made of stainless steel SUS304 or SUS316L. heat preservation adopts sand frinding surface polishing treatment. All is in accordance with GMP stangard. Volume has different specifications ranging from 100L to 20000L.
