 Vacuum Belt Continuous Dryer For Powder

The vacuum belt continuous dryer for powder is a high efficiency piece of drying equipment. The powder dryer features excellent thermal efficiency, low energy consumption and it produces finished products with consistent results. These dryers are commonly used for drying thermally sensitive, sticky and materials containing solvents. The vacuum dryer has a recoverability of 95%, which is outstanding. Our equipment is designed for drying all sorts of materials, so if you provide us with your specific requirements, we can help you find the exact machine you need.

Belt Vacuum Continuous dryer( click for download )

Range of application:
1. Medicine, food, food additive, chemical raw material;
2. All kinds of raw materials including powder, crystal, granule and fruit;
3. Materials which are oxidizable, explosive, strongly simulating and highly toxic;
4. Products containing various recyclable solvents.

Working principle
This drying machine features a design with a vacuum chamber where a material conveying guide belt (Teflon PTFE) is installed. Materials are distributed continuously on the guide belt after they pass through the continuous vacuum distributor at the top of the machine (adjustable distribution thickness 3mm-30mm). The guide belt conveys the material slowly to the other end while the heating zone (40℃-180℃) below the belt evaporates moisture within the compound. Evaporated moisture is quickly removed via the vacuum system. The compound automatically falls onto the second layer guide belt when it reaches the end. The process repeats until the desired dryness is achieved. When it is finished, materials will fall into the conveying chute at the discharging end where a screw conveyor will deliver it to other processing equipment to be ground, sieved and pulverized.

Notes 1.The yield is calculated based on70%content at 90℃drying temperature with dry power containing about ≤4% moisture. In case the dried liquid is water, specific qravity of the dry power is determined to be 1. The yield will be larger if the drid liquid is solvent.
2. All techincal parameters are for reference only depending on the materical conditions,and our company has the right to change them without further notice.

1.It meets the GMP hygienic requirements to realize drying by finishing continuous charging,continuous discharging and grinding under vacuum condition;
2.It can realize controllable drying temperature(40℃-80℃) ,unchanged thermal sensitivity of materials,recoverability of 95%solvent as to solvent materials and vacuum drying of oxidizing materials without oxidation;
3.It can finish drying,grinding,and granulating under vacuum condition;
4.Continuous discharging starts after 20--60minutes,with product yield up to 99%;
5.Highly sticky materials will not stick to the belt(which is Teflon PTFE),and crystal materials will not damage the crystal form after drying;
6.The moisture content of the dried product can optimize such major parameters as temperature,vacuum degree and speed of the drying process,enabling the utilization of the equipment to achieve the best economic benefit;
7.It adopts PLC automatic programming control system to realize high-degree automation and greatly reduce labor operating costs;
8.Its operating cost is only one third of or even lower than of its similar drying equipment;
9.CIP automatic online cleaning system with various cleaning methods can clean the equipment completely and quickly after drying and meet the GMP requirements;
10. It is suitable for large-scale,continuous and automatic operation.
