Application characteristics of closed loop spray dryer

14-11-2019

The closed loop spray dryer is a new type of spray drying system that is widely used in the food industry. The following small series for everyone to talk about the characteristics of the closed-loop spray dryer in practical applications, I hope to help everyone.


The closed-loop spray dryer can exchange heat between high-temperature inert gas and wet materials to achieve the drying effect. After the inert gas with higher humidity and lower temperature is cooled and dehumidified by the dehumidification washing tower, the clean inert gas is reheated by the circulating blower and then re-heated, and the cycle is continuously used to complete the drying. The closed-loop spray drying system has the following characteristics in practical applications:


Environmental protection: Closed, closed-circuit operation of the drying system of the closed-loop spray dryer, no waste gas and dust emissions during drying, avoiding environmental pollution.


Safety: The closed-loop spray dryer is very safe during the entire drying process because the danger of oxidative decomposition or explosion of the material is relieved under the protection of inert gas. The system is equipped with an automatic oxygen meter, automatic nitrogen supplement and alarm device, and a PLC control system, which has extremely high safety.

Energy-saving: The closed-loop spray dryer is designed reasonably. In the process of drying, the outlet temperature of the inert gas with high moisture content is usually very low. When the outlet temperature is increased to a certain value, the material has reached the wet content requirement of the finished product, unlike the general The airflow drying device needs to maintain a certain value of the moisture content of the finished product, and the outlet temperature needs to maintain a certain value for a long time. With this drying method, the energy consumption is greatly reduced, and the purpose of energy saving is achieved.


High efficiency: The closed-loop spray dryer has high drying efficiency, large output, and fast drying speed. The drying process is carried out under the protection of inert gas. The material is not easy to oxidize and yellow, no need to clean each time, saving cleaning time and improving production efficiency.


The above is about the application characteristics of the closed-loop spray dryer. I hope that everyone can understand the application characteristics of the closed-loop spray dryer, and it is helpful for everyone to understand the closed-loop spray dryer.
