In the traditional ways, it is to use sunshine to dry the alfalfa which is influenced by weather significantly, and it is not suitbale massive alfalfa drying process. Thus it is necessary to use the alfalfa drying plant.
Alfalfa drying system mainly includes alfalfa chopping machine, rotary alfalfa dryer, burner, hot air furnace, air duct, draft fan, chimney, electric control cabinet, inlet belt conveyor, outlet belt conveyor, inlet feeder, outlet feeder, cyclone separator, etc.
The key equipment of alfalfa drying plant is alfalfa drying machine which is developed and optimized from traditional rotary drum dryer. It is to use high temperature flue gas to heat and dry wet alfalfa quickly and continuously.
As for the stem and leaves, its needed drying time is different. what is more, long alfalfa would be stuck inside the dryer cylinder. Thus, in order to have the stable dry product, before the drying process, usually to use alfalfa chopping machine to cut the alfalfa into smaller pieces less than 10mm in advance. To do it this, way, the flowing ability of smaller pieces alfalfa will be better, and it can pass through alfalfa drying machine smoothly.
Regarding to the fuel for alfalfa drying system, the related fuel choice can be waste wood, biomass fuel, coal, diesel, natural gas, LPG, etc. For different kind of fuel, the needed hot air furnace's design also will be some different. Sunco Machinery can design and supply the related hot air furnace according to the fuel that the customer selected.
1. High temperature flue gas drying.
2. Short drying time, about 15 minutes.
3. Stable quality of dry product.
4. High heat efficiency.
5. Compact structure and less land area needed.
6. Easy operation and less maintenance cost.
