¡ñThe material sends in by the spiral conveyor stirs in the water extractor, the hot blast enters the water extractor and the stave material contact after the feeding end tangent bearing preliminary dry, in the agitation impetus and under the air current dual function, the material backward moves and is stirred unceasingly the fingernail to raise and stave, and carries on the full mass transfer heat transfer with the hot blast, the finely ground particles and the wet air simultaneously backward moves, is high compared with the big material pellet water content, the resident time can lengthen suitably, therefore, agitation dry part even if enters 300-500¡æ the hot blast, expects warm cannot too be high. In stirs behind the water extractor, the material in copies under the board and the air current dual function, enters in the cyclone by the ascendant current pipeline (to select).The introduction supplement hot blast urges material acceleration revolving, flows to, the wind speed using the air current and two gusty the waste gas after the proliferation type cyclone separator separation dust, draws out the emissions again by the air blower. The overall system uses the negative pressure operation. Mainly applies in chicken manure, distiller's grain, clay and so on coherent material dryness.  

¡ñLeaf blade's mixing speed is quick, outside the edge circumferential velociy is 5-15m/s, the material and the hot blast contact, the critical wet content is low, may reach 2%-3%, the heat transfer coefficient may reach 1200-4100kJ/(h.¡æ.m³); 
¡ñThe drying time is short, is generally 2-15min, in the water extractor the material detention quantity are few; As a result of agitation leaf blade's porphyrization, regardless of therefore joins the material is massive or other shapes, all may obtain the powder granular product after the drying; 
¡ñIs suitable specially for sticks the material the disperser to be dry. 
¡ñMay according to agitation adjustment turnover material time and so on leaf blade angle and rotational speed; 
¡ñMay act according to the material characteristic to be different, chooses the different agitation form or the turnover material form.
