Lines of drying

Lines of drying

We project in a complex manner and we construct lines of drying of the raw minerals used, inter alia, for production of wooden pellet, agro pellet and fuel waste (RDF – Refuse Derived Fuel), drying byproducts of the vegetable industry (e.g. pomaces of fruit and vegetable, food and in managing waste (e.g. biogas station post-ferment).

We possess reliable technology of drying all powder materials. We constantly improve our offer while conducting the research, due to which we obtain excellent effects in  drying raw minerals with even very high humidity (up to 85%).

For our clients we propose the tailored solutions for tailored – adjusted to itheir individuals needs and including specific features of raw minerals. We perform belt, drum, viral (reactor) driers and even hybrid in order  as a result to obtain the line with with the largest capacity.

Charakteristics driers

Drum driers

Among drum driers one may distinguish two types thereof: traditional driers, using in the drying process the fumes and driers with  fumes-air exchanger. The undoubtful plus of these first two are low costs of exploitation and simple construction. While deciding to choose this type of drier one should remember that due to the direct contact of fumes with the product dried at the inlet to the drier we observe the occurrence of high temperatures (even above 600 ℃), which pose a threat to the ignition in during the drying. In addition, the product obtained as a result of the process is characterized by not high quality. The driers with fumes-air exchanger are deprived of these defects. In their case, the risk of the ignition to occur is much smaller and the final product is characterised by higher quality. The solution of that typ eis however cheaper due to  furnace of special construction and heat exchanger. The costs of exploitation are also a little higher which indirectly results from higher consumption of energy.

Drum driers are perfect in druing sawdust, fruit pomaces, post-ferment, etc.

Belt driers

Belt driers are characterised first of all, by a high quality of the finished product. A large advantage are low working temperatures, to reduce the risk of ignition almost to zero. These are however the more expensive solutions, which require small space due to large sizes and the necessity to build the boiler room based on water boiler. They are mainly used for drying fruit and vegetables for the needs of the grocery industry but they are perfect also in drying sawdust, post-ferment and others.

Viral driers (reactor)

This is a specific type of a drier possessing almost only advantages. First of all, it includes high quality of the finished product comparable with the one obtained due to the belt driers. In addition, in the issue of supply of thermal energy, they create a possibility to choose bettwen the exchanger and mixer of air. Thwy work in relatively low temperatures (on average 120-200 ℃), and their exploitation costs are approximate to costs of exploitation of drum drier.

Hybrid drying lines

Hybrid solutions, namely the connection of a drum or belt drier with the viral one are more beneficial for the whole process. They increase its capacity, improve the quality of the final product, whereas they not raise costs. They are intended for the clients who want to increase capacity ot improve the quality of the existing driers. The costs of such a modernization are much lower than the construction of the drier from the scratch. A small financial outlay is enough to  realize the effectively functioning hybrid drying line.
