1.6 pulsed fluidized bed for a number of easy flow of materials and the drying temperature must not exceed the crystalline drug 50 ~ 80 ℃, the development of the pulsed fluidized bed. Pulsed fluidized bed changed the conventional fluidized bed constant periodic air blowing, fluid bed drying maintenance problem by adjusting the air flow pulse frequency or pulse airflow conduction rate, so that the gas flow through the orifice or fluidized Zone changes periodically, the material is dried. The main structure is characterized by drying the wet around the bottom of the hot air inlet tube fitted with a few fitted with pulse valve on each of the hot air pipe, they open at a certain frequency and order, on time and bed thickness and material properties related When the gas is suddenly introduced, in a short time to form a pulse, intense fluidizing the particles, prompting conduct intense heat and mass transfer between the material, when the valve is closed, fluidized bed state gradually disappears, the material at rest, while still part of the gas fed through the bed, so that the next pulse can be effectively transmitted in the bed. The advantages: high heat transfer coefficient, fluid bed drying sales problem, short drying time, reducing air consumption, power consumption is low. Pulsed fluidized bed can overcome channeling dead zones and local overheating of the drawbacks of traditional common fluidized bed, which can be used to handle viscous, easy agglomeration and heat-sensitive materials, fluid bed drying cleaning problems, such as tetracycline class antibiotics. XF Series Horizontal Fluidizing Dryer works: clean and hot air through the valve plate distribution into the bed body, forming boiling from the feeder into the wet material is hot air. Due to extensive contact between hot air and materials, increasing the heat and mass transfer process, so in a relatively short period of time can dry. As with continuous, fluidized bed drying, the material enters from one end of the bed, after several minutes, boiling dry, automatically out from the other side of the bed. This equipment is generally negative pressure operation. XF Series Horizontal Fluidizing Dryer Application: medicines, chemical raw materials, food, food processing, feed drying operation. Such as: API, tablet granules, Chinese traditional medicine, health food, beverage powder, corn germ, feed, plastic resin, citric acid and other powders dehumidification drying. Applicable material particle size is generally 0.1-6mm, optimal particle size 0.5-3mm. Fluidized bed drying maintenance problems, the drying step (certified), fluidized-bed drying step by Changzhou Drying Equipment Co., Ltd. Drying Equipment Co. Changzhou step (www.yibu.com) is a leader in Changzhou, Jiangsu, drying equipment, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
