How to start up a continuous Oslo cooling crystallizer?
Thread Content
We use an Oslo crystallizer for the cooling and crystallization of organic substances; the organic substance at 50°C is poured into the crystallizer where it cools down slowly on its own. It was originally planned to carry out centrifugal drying when the temperature dropped to 5°C, but due to the extremely slow natural cooling, after 4 days when the temperature fell to 30°C, it was found that the crystals in the crystallizer were as large as mung beans, and they clumped together at the bottom of the crystallizer, making it impossible to extract the product. What should I do? Is the way we drive correct? If it’s not correct, how should it be entered?
Crystallization and separation can take place simultaneously. Two questions: 1. Is there no forced circulation pump? 2. If crystallization is so good, why use natural cooling? ? ?
1. Is there a forced circulation pump? 2. There was frozen saline; after it had been flowing for 1 hour, it was found that the condenser was clogged. So it can only cool down naturally.
Feed the material, start the circulation pump, heat and concentrate it; once the solid content meets the required level, proceed with centrifugation to separate the product, and recycle the filtrate.
