For materials with high viscosity, easy to absorb moisture and easy to oxidize, continuous feeding and discharging under low temperature vacuum environment. Great retention of material aroma, activity, taste.

 

Vacuum belt dryer Areas of application:

The QFY series negative pressure low temperature rigid belt dryer is a new type of drying equipment developed by Shanghai Qiaofeng industrial Co,Ltd. The equipment has a diameter between 0.8m and 0.32 m, a length between 5 and 18 m, a material belt between 1 and 12 layers and a evaporation capacity between 0.5kg/h and 200 kg / h. The equipment can be selected according to the needs of production.

For a long time, many materials in pharmaceutical, food and fine chemical industries are difficult to dry in ideal condition. This equipment not only solves the drying problem of extract and polysaccharides in traditional Chinese medicine industry, but also applies to health products, Low temperature drying of raw materials in biopharmaceutical industry, especially for materials with high viscosity, easy coking and heat sensitivity. So it is the best choice for low temperature continuous dryer.

Product advantages

1, Integrated various drying advantages in one of the high-efficiency energy-saving drying equipment, is regarded as the most economical, the most moderate drying method;

2, Materials are always in high vacuum state low temperature drying, can meet most of the requirements of the production of thermosensitive materials, and retain the material characteristics of the product;

3, When the dry material moves with the caterpillar track, the relative position between the materials is fixed and has the same drying time;

4, The moisture content of the material from liquid drying to solid powder decreased uniformly with the drying time of the material.

5, The drying machine made the dry products become porous and loose, the surface area increased significantly, and the solubility of the products was improved obviously.

6, The wet materials are preheated into the track to complete the constant speed drying. The feed quantity, the material take-off speed, the temperature and humidity, the vacuum degree and so on can be adjusted on line.

Vacuum belt dryer  Product characteristics

1, The material layer has 1 to 12 layers for the user to choose, according to the user requirements;

2, The whole drying belt is provided with a plurality of heating zones and a cooling zone;

3, Track running smoothly, reliable and track material has stainless steel or Teflon for user to choose;

4, The collocation tank has the function of heating and stirring the jacket to maintain the fluidity of viscous liquid and the uniform addition of auxiliary materials.

3, The servo feeder can replace the nozzle and can distribute evenly even when the feed is very small;

4, Each layer can be constant and well-distributed feed and the feed speed can be online accurate adjustment;

5, Each heating plate is equipped with an independent heating system to achieve 50℃-150℃ drying temperature parameters adjustable.

6, Variety of heating sources: microwave heating pipe, steam heating, superhot water heating, heat conduction oil heating for choice, temperature can be automatically controlled;

7, Different drying curves can be set according to different products.

8, Each layer of cooling plate is equipped with cold water system, the process temperature parameters can be adjusted, running around 7-12 ℃;

9, Most of the rollers have the function of correcting deviation and adjusting tension.

10, Each track can independently control the speed of movement independently.

11, Continuous work, suitable for high viscosity raw materials, multi-variety production;

12, Under the vacuum condition, continuous feeding and discharging, the drying process temperature is controlled at 60-90 ℃, the heat sensitive material is invariant.

13, Retain aromatic smell, can solve high viscosity, difficult to dry all kinds of liquid materials, product shape for porous particles;

14, The drying time was 30-60 minutes and the product yield was over 99%;

15, Uniform cloth, track constantly moving heating and cooling, dry into a thin sheet;

16, The material is cooled after drying to reduce the oxidation, so that the adhesion force between the material and the track becomes very small, thus leaving the track easily;

17, After drying the material has a porous structure, the product has excellent instant solubility after crushing to the required particle size directly;

18, The density of dried cake is 200-250 kg / m3, and the density of dry cake after crushing is 400-500Kg/m3.

19, Built-in crushing granulation device, the final size of the discharge particles in the 20-120 mesh, the appearance of the particles;

20, The whole process is closed in the vacuum state continuous discharge dry material, comminuted, high speed granulation, sieve and vacuum automatic feeding;

21, The discharging end of the dryer is equipped with the discharging cone bucket and the valve gate, and the cone bucket is provided with a stirring device to prevent possible adhesion and bridge connection;

22, There is a certain degree of crystallization in the drying process of the product, the particle fluidity after crushing is good, can press the tablet directly or fill the capsule, which is convenient for the production of the product;

23, The equipment is equipped with sufficient vacuum pumping capacity to allow the drying box to operate at a vacuum below 10mbar;

24, Good air tightness of dryer, including discharge system, loss of pressure per hour not exceeding 5mbar;
