How To Pick Drying Tools
1, The best way to Choose The proper DRYING Gear AND DRYING AND DRYING Technique for remedies
Generally speaking, spray dryer is the very first alternative for answer drying. That's true for even bigger ability of drying undertaking. For smaller capacity of drying venture, this kind of as 50Kg to 2000Kg of drinking water evaporation daily, warmth pump dryer is the best choice. For some answers with non-viscosity, fluid bed dryer with inertia particles is the best option.
one), the capital cost of spray dryer may be the greatest between all the drying tools. For the smaller sized capability, its relative money price is even larger;
2), it requires lengthy time to clear up the devices if it truly is employed to dry more than 1 kind of answers;
three), it needs operators when it truly is running;
4), vitality value is higher, for lower inlet temperature.
Heat pump dryer can prevail over the above down sides for tiny potential:
1), its capital cost is very low, because of its basic drying method;
2), its vitality expense is low, because of its state-of-the-art functioning principle , specifically for tropical area in which humidity is pretty large. Heat pump dryer is impartial with the change of climate. Higher humidity has damaging result on power cost of drying technique with lower inlet temperature;
3), it really is probable to dry a few sort of remedies at the exact same time without having any influence on each other remedy;
4), no operator is required when it really is working, simply to set in solution and take out dried item.
Fluid bed dryer with inertia particles is pretty efficient for all those options with non-viscosity:
one), money value is rather lower, for its greater drying intensity;
2), the dimensions of dried product is its unique size, which can be rather important in a few industries;
3), large ability is also probable.
two, How to Pick The right DRYING Gear AND DRYING AND DRYING Program for sludge, slurry and cake.
For these kinds of materials drying, you can find various worries for various client and task, this kind of as its funds value, its electricity value, the dimension of dried merchandise.
There are over three kinds of drying gear can be used to dry these components: warmth pump dryer, paddle dryer, rotary dryer with disintegrator, spin flash dryer, vacuum dryer.
For modest drying potential, as much as 2 or 4 plenty of water evaporation daily, heat pump is the best option:
1), its capital expense is low, for its basic drying approach;
two), its power expense is reduced, because of its advanced doing work principle , specifically for tropical place where humidity is quite higher. Heat pump dryer is independent in the change of weather conditions. Large humidity has negative impact on power price of drying method with low inlet temperature;
three), no operator is needed when it can be functioning, simply to put in solution and consider out dried product.
For the medial drying ability, from 2 to 100 plenty of h2o evaporation every day, without any worry about the dimension of dried item, paddle dryer is the best choice:
one), its money expense is low, for its straightforward drying method;
two), minor exhaust from drying system, so it's simple to offer with its odour;
three), simple functioning. it truly is batch operation.
For the massive drying ability, from 20 and 500 tons of h2o evaporation every day, granular dried item is necessary, then rotary dryer with disintegrator is the best option. It will also be utilized as the first stage dryer, fluid bed dryer/rotary dryer be employed as second dryer. This mixture has the following good points, specially for industrial and municipal sludge:
one, Rotary dryer with disintegrator functions as the very first stage dryer and disintegrator in the exact same time. It entirely replaces the mixer inside the other program, for most of sludge are sticky and have to blend with dried material just before drying inside the other drying technique;
2, fluid bed dryer/rotary dryer works as the 2nd stage dryer, heat recovery product and cooler in the exact same time. Furthermore, it prolong drying time, for your drying time in rotary dryer is just not extended ample for higher h2o content material substance because of the duration of rotary dryer with disintegrator;
3, 70% of exhaust from second dryer may be recycled to the very first stage dryer. It minimizes the load for off fuel remedy equipment;
four, only fluid bed incinerator, rotary dryer with disintegrator and off fuel treatment gear are required for sludge incinerating system. For your dimension of dried sludge from rotary dryer is about one to 4 mm in diameter, it truly is the appropriate dimensions for fluid bed combustor.
five, The lowest investment. The reasons are as follows:
1), basic construction and quick length for rotary dryer;
two), no vibrating screener, crusher, mixer and cooler;
6, Large effectiveness in energy utilization due to large inlet temperature. The inlet temperature could be as large as 850C, it's the very best inlet temperature for these sort of components drying.
3, The way to Pick The best DRYING Equipment AND DRYING AND DRYING System for granular components
More than 50 percent resources need to be dried are granular materials and there are a lot of sort of drying equipment can be utilized to dry granular components. In line with the drying capacity, the dimensions of supplies, the kind of power currently being employed for drying procedure, their chemical property, such as, viscosity, warmth sensitivity, the kind of water inside components, toxicity,
fluidized bed dryer, rotary dryer, flash dryer, vacuum dryer, heat pump dryer, paddle dryer, drying oven, belt dryer, etc can be utilized.
4, The best way to Decide on The proper DRYING Equipment AND DRYING AND DRYING Program for large size of materials
For your drying of massive size of components, this sort of as parts, agricultural products, etc may be dried by belt dryer, warmth pump dryer, rotary dryer, drying oven, etc.
five, The best way to Decide on The best DRYING Tools AND DRYING AND DRYING Technique for unique resources, such as recovering solvents, flammable, explosive, poisonous, and so forth.
For special material drying, such as flammable, explosive and toxic resources, and components drying must recuperate solvents, you will find the next kinds of drying equipment: heat pump dryer, vacuum dryer, fluid bed dryer, spray dryer, etc.
