Brief introduction to the advantages and disadvantages of vacuum harrow dryer

Advantages of vacuum harrow dryer:

(1) Strong adaptability, wider application As the harrow vacuum dryer uses jacket heating and high vacuum exhaust, so it is adaptable to almost all materials with different properties and states, especially adaptable to the drying of easily oxidised, explosive, strongly irritating and highly toxic materials.

(2) Good product quality Because of the drying process, the rake teeth constantly rotate positively and negatively, the dried materials are stirred evenly to avoid overheating of the materials, and the moisture is easy to escape, and the shell gets the products with low temperature. Due to the fine particle size of the product, it can be packed without crushing.

(3) Small steam consumption As the vacuum harrow dryer uses steam to pass into the jacket, using latent heat to heat the material, the steam consumption per kilogram of finished product is small, generally 1.3-1.8 kg of steam.

(4) According to the different characteristics and requirements of the dry materials, the sealing system of the dryer can choose two kinds of packing seals and mechanical seals, and the special design ensures the sealing and service life.

(5) Easy to operate Vacuum harrow dryer is easy to operate, less staff, low labour intensity. Due to the loss of material escape is reduced, improve environmental health.

The main disadvantages of vacuum harrow dryer are: complex structure, expensive. Because it is intermittent operation, drying time is long, low output; and because it is not easy to clear the material, so it is not suitable for the production of frequently changing varieties. At the same time, in order to ensure the vacuum degree, must often maintain the maintenance of the vacuum device.
