The characteristics of the vacuum rake dryer
Vacuum rake dryer has the characteristics of the five aspects:
(1) strong adaptability, widely used Because the vacuum rake dryer using jacketed heat, high vacuum exhaust, so almost of all state of different nature, different materials are used to, especially for explosive, easy oxidation, paste material drying.
(2) the products are of good quality Due to the drying process, the tine is positive and negative rotation, material mix is dry, avoid overheating in the material, moisture and easy to escape, shell be products of low temperature. Because the product particle size, do not need to crush can packaging.
(3) the steam consumption is small Due to vacuum rake dryer multi-purpose steam into the jacket, use of latent heating materials, processing the finished product cost per kilogram steam is small, generally 1.3 1.8 ㎏ steam.
(4) according to the different characteristics and requirements of dry material, drying machine sealing system can choose two kinds of packing seal and mechanical seal, special design to ensure the tightness and service life.
(5) easy to operate the vacuum rake dryer is easy to operate, less capacity, low labor intensity. Due to the material to escape and loss, improve the environmental health.
Vacuum rake dryer is the main drawback of: complicated structure, the cost is more expensive. Because it is intermittent operation, the drying time is long, lower productivity; And due to not easy off material, so not suitable to produce often exchange varieties. At the same time, in order to guarantee the vacuum degree, must often maintenance vacuum device.
