The volume of the reactor body is determined by the charging amount, and the appropriate height-to-diameter ratio is selected according to the volume of the tank body, and the diameter and height of the cylinder body are also determined. When selecting the height-to-diameter ratio of the tank, consideration should be given to factors such as the requirements of the material characteristics on the height-to-diameter ratio of the tank, the influence on the mixing power and the influence on the heat transfer.

From the perspective of heat transfer in the jacket, it is generally desirable to take a larger height-to-diameter ratio, and the larger the diameter of the tank body, the greater the stirring power. According to practical experience, when the material in the tank is liquid-solid phase or liquid-phase material, the height-to-diameter ratio of the stirred tank is 1:1.3; when the material in the tank is gas-liquid material, the height-to-diameter ratio of the stirred tank is 1: 2.

The nozzle of the reactor: the feed pipe is usually installed on the lid of the reactor, but can also be installed on the tank body. The discharge pipe is usually installed in the center or side of the tank bottom, and the position where the material can be drained is selected according to the actual situation. The connection forms of the connection port include thread, flange, quick-fit union or hose, etc. For situations where solid materials need to be added to the mixing container during the mixing process, a feeding port can be set at an appropriate position on the tank lid. If the mixing tank is under negative pressure, the vacuum suction principle can be used to feed the material from below.

The reactor is a mixing equipment used in food, chemical, pharmaceutical and other production lines. The proper height-to-diameter ratio and nozzle design can bring higher production efficiency to the production line.
