The invention relates to a belt type fluidized drying machine which belongs to the field of forage machinery. The belt type fluidized drying machine comprises a shell, a hot air conveying device, a dust-collecting device and a draught fan, wherein a netted belt conveying unit is horizontally arranged in the shell; the netted belt conveying unit comprises an upper-layer netted belt and a lower-layer netted belt; a plurality of material-picking plates are uniformly, equidistantly and fixedly arranged on the surfaces of the upper-layer netted belt and the lower-layer netted belt along the length direction; a porous material plate which is used for receiving dropping materials transmitted by the upper-layer netted belt is arranged under the lower-layer netted belt in a parallel form; the porous material plate is fixed with the shell; the materials on the porous material plate are divided into a plurality of independent material drying units by the material-picking plates; the materials in each of the material drying units are under boiling fluidized drying state by adjusting the volume of hot air which upward passes through the porous material plate; and the materials in each of the material drying units are forward conveyed following the propelling of the material-picking plates during the drying process. The fluidized drying state of the material layer is realized by using the belt type fluidized drying machine; the drying efficiency and the drying uniformity are increased; and the materials are loaded by both of the upper and lower netted layers, so that the use ratio of space is increased.

The invention discloses a drying device for mechanical parts with a central hole. The limiting rods set by the parts; the blocking mechanism, the blocking mechanisms are multiple groups, and the multiple groups of the blocking mechanisms are respectively used to prevent the mechanical parts from sliding down from the multiple limiting rods under the action of their own gravity; the driving part , the driving part is used to provide a driving force for the pull rod to move vertically in the installation opening. Through the cooperation of the blocking mechanism and the driving part, when the rotating plate is rotating, the parts on the plurality of limit rods on the upper surface of the rotating plate will not slide off from the limiting rods, and the blocking mechanism will not work at this time. It is convenient for the staff to take it, and multiple sets of blocking mechanisms on the multiple limit rods on the lower surface of the turntable will work to prevent the parts from slipping and avoid the cumbersome steps of installing the stopper.

The invention belongs to the field of agricultural product drying, and particularly relates to a method for drying Hami melon slices by a nitrogen source low oxygen heat pump. The method comprises the steps of selecting Hami melons, removing peels and pulp of the Hami melons, conducting slicing, conducting color protection and type fixing, blanching, draining, conducting drying in a nitrogen source heat pump drying machine, and conducting drying, sealing and storing in a vacuum drying box. According to the method, the drying energy consumption is reduced, the drying efficiency is improved, the defects that in the drying later stage, the heat pump is low in drying efficiency and long in time required by drying are overcome, heat pump drying and vacuum low-temperature drying are carried out after color protection and blanching treatment, and therefore the problems that the brightness of the Hami melon slices is reduced, and the color is changed are solved. According to the method, phenolic substances in the Hami melon slices can be restrained from being oxidized to generate quinone, the oxidation loss of vitamin C is reduced, damage, caused by oxidation in the drying process, to the color and texture of the Hami melon slices can be avoided, and dried products with the natural color are obtained.
