Changzhou and being dried under vacuum rake dryer energy saving quality assurance
2015-06-19 Reads : 59
And the material being dried under vacuum rake dryer means indirectly heated with steam jacket materials, and under high vacuum exhaust, and therefore is not particularly adapted to high temperature, the material susceptible to oxidation at high temperatures likely to occur during or dry powder (such as various fuel), as well as material drying process steam or solvent excluded drying operation must be recovered. Rake vacuum dryer is dried material moisture content or solvent content of up to 90%, while the lowest is only 15%. Dry material has paste, paste, granular, powdery, it can be fibrous. After drying the moisture content of these materials typically 0.1% or even 0.05%. Founder of dry material from the housing to join the middle, stirring constantly rotating rake teeth with the housing wall when the material contacting surface constantly updated, dry material is indirectly heated by steam, leaving the material moisture vaporization 2, gas of water pumped by the vacuum pump in a timely manner, the machine can simultaneously use mezzanine and finger while heating mode, a larger heat transfer area, high thermal efficiency, so that higher drying efficiency. Due to high vacuum operation, the material to be dried is much greater than the surface of the water vapor pressure of water vapor pressure in vivo evaporation drying cabinet space, which is conducive to being discharged DRYING water and surface water, the movement of water molecules in favor of the material to be dried , the purpose of drying. Features (1) adaptability, wider application due to the use of rake vacuum dryer heating jacket, high vacuum exhaust, so almost all of the different nature of the material have to adapt to different states, especially suitable explosive, oxidizing, cream like materials dry. Good (2) product quality due to the drying process, the finger constantly reverse rotation is stir dry material, to avoid overheating of materials, moisture can easily escape the shell to obtain a low temperature products. Due to the fine granularity, without grinding to packaging. (3) steam consumption small because the vacuum rake dryer more steam through the jacket, the use of latent heating materials, processing of finished consumption per kilogram smaller amount of steam, usually 1.3-1.8㎏ steam. (4) easy to operate vacuum rake dryer easy to operate, low capacity, low labor intensity. As the material to escape losses reduced, improving environmental health. Rake vacuum main disadvantages are: structural complexity, cost more expensive. Due to intermittent operation, long drying times, low stocks yield; and because the material is not easy clearing, exchange varieties and therefore not suitable for regular production. Meanwhile, in order to ensure that the degree of vacuum, vacuum devices must be regular maintenance overhaul. Applicable materials high muddy paste 100 mesh material of various pigments, dump-like material was filtered and centrifuge filter and soda detergent, alkali stone starch, dyes, pigments, clay, clay, ash, etc., etc. I have another cement company is equipped with prototype welcome new and old customers in raw material testing.
