Batch Reactor - an overview | ScienceDirect Topics

A semi-batch reactor will have some addition and/or removal during the course of the reaction; a T-flask is a semi-batch reactor if media is changed between passages. Batch reactors can be operated as static or mixed; a T-flask is static (Fig. 3.1) and a stirrer flask, such as a Techne Flask (Fig. 3.2) is mixed. Mixing helps remove ...

Nov 20, 2014 3. Spray cooling • This method is similar to spray chilling, the only difference is the temperature of the reactor in which the coating material is sprayed. A molten matrix material containing minute droplets of the core materials may be spray cooled. Also, vegetable oil can be used and the normal melting point is 45–122 C (Risch, 1995).
