Conveying chain plate of vegetable drying machine
InactiveCN103954119ANot easy to compactGuaranteed drynessDrying solid materialsFood treatmentContact modeFriction force
The invention discloses a conveying chain plate of a vegetable drying machine. The conveying chain plate comprises two side plates, wherein one end of each side plate is in an arc shape, the side plates are provided with convex chain connecting ribs, the chain connecting ribs are closer to the arc-shaped ends of the side plates, and a conveying plate is connected between the two side plates; the conveying chain plate is characterized in that the conveying plate is a waved plate, the waved plate is fully provided with through holes, and the extension direction of waves of the waved plate is vertical to the side plates. Compared with the prior art, the conveying chain plate of the vegetable drying machine, designed by the invention, has the following advantages that firstly, since the conveying plate is the waved plate, the through holes cannot be compactly pressed after vegetables are placed on the waved plate, ventilating can be formed by most of the through holes, and the drying effect is ensured; secondly, a contact mode between the conveying plate and the vegetables is changed from surface contact to line contact, the friction force is reduced, and the blanking can be smoother during blanking.

Rigid and flexible composite bio-fillers for deodorization by bio trickling filtration and method for preparing same
InactiveCN101333033BHigh mechanical strengthGood stretchabilitySustainable biological treatmentBiological water/sewage treatmentCross-linkFoaming agent
The invention discloses a rigid-flexible combined biological filler for biological trickling filtration deodorizing equipment and a preparation method thereof; the biological filler is formed by combining a rigid macromolecular skeleton at the center and flexible biological carrier porous medium at the periphery. During preparation, sustained-release control matter is firstly moistened by dispersing and lubricating liquid and evenly mixed with nutritive matter in an agitator, then macromolecular base material is moistened by the rest dispersing and lubricating liquid, added in the agitator and evenly stirred together with the mixture, the evenly mixed mixture is transferred in an injection machine and is extrusion molded by filler dies to prepare the rigid macromolecular skeleton; the rigid macromolecular skeleton is blended with polyether polyol, organic isocyanate, catalyst, external foaming agent, foam stabilizer and water, stirred at high speed and added into a forming box to finish chain growth, foam formation, cross linking and solidifying reaction, thus obtaining the biological filler. The filler of the invention has wide source of raw materials, convenient and simple manufacturing procedure, low production cost, and good film-forming and deodorizing effects.
