Medical particle vibration fluidized bed on-site operation video

‌Pharmaceutical particle vibration fluidizationbedThe principle ofMainly based on the principles of fluid mechanics of gas-solid two-phase flow, solid material fluidization and suspension are achieved by adding vibration inside the bed under the action of gas-solid two-phase flow. This device generates strong mechanical waves through mechanical vibration, which work together with the airflow to cause collisions between particles, thereby achieving material fluidization and dispersion. In vibration fluidizationbedIn the bed, a fluid like behavior is formed through the action of gas-solid two-phase flow, which can improve the mass transfer, heat transfer, and reaction performance of solid materials. Therefore, this device is widely used in various fields such as drying, particle modification, and reaction processing.

Specifically in the drying process of pharmaceutical particles, vibration fluidizationbedEfficient drying can be achieved through the following methods:

• ‌Material fluidizationThe material is fluidized by the dual action of mechanical vibration and perforated airflow, and moves forward under the action of vibration.

• ‌Heat and mass exchangeHot air enters from the perforated distribution plate from bottom to top, and the material is fluidized in the fluidized bed by the hot air and vibration, while undergoing heat and mass exchange.

• ‌Drying and CoolingThe dried material is cooled and transported by vibration to the discharge port, and the cold and hot air are discharged from the exhaust port on the upper part of the shell.

In addition, due to the strong vibration of the bed, the resistance of heat and mass transfer is reduced, which improves the drying rate of the vibrating fluidized bed, and also enables the smooth drying of bulk or highly dispersed materials that are not easily fluidized or are prone to be entrained during fluidization. This overcomes ordinary fluidizationbedThe disadvantages of easy occurrence of backmixing, channeling, wall sticking, etc. are widely used in the production of drying, cooling, and granulation in the pharmaceutical, food, chemical, and feed industries
