Abstract
A dual-drum drier is composed of two drying drums, two scraper sets and feeder. Two drums are supported by 4 adjustable supporters, driven by electric motor, speed reducer and transmission unit, and heated by rotary joint and syphon tubes for heat exchange. Its advantages are instantaneous drying and saving energy greatly.
Description
The present invention relates to a kind of food drying machinery, especially the drying equipment of forming by roller, inlet and doctor blade device.
Roller dryer is in heat conducting mode, and the liquid phase material that needs are dried places roller surface, makes material add a kind of continuous drying machinery of thermal maturation.Single roller dryer of extensive use in the market, structure are that the external peripheral surface at single only logical heated drying roller is glued with the doctor blade device that is used to scrape by oven dry material film.Also be provided with forward roller and a reverse rollers of many rotations simultaneously, many forward and reverse rollers form a plurality of slurry tanks and make material hot digestion repeatedly in each slurry tank on the surface of single drying roller.And the hot digestion of this multiple-grooved repeatedly exists the excessively defective of (wearing out) of slaking, product interior quality to be difficult to improve on the one hand, the incompatible material that needs the instantaneous drying of high temperature, and the production of especially high-quality α starch needs; On the other hand, every forward and reverse roller forming a plurality of distributing troughs, all and have the multiple sticking glutinous resistance that forms by the material boiling between the drying roller, make entire equipment energy consumption height, processing cost is big, the roller of an effective working width 2m when producing α starch in the actual use finished product power consumption per ton all 350 spend more than.
The purpose of this invention is to provide a kind of instantaneous roller dryer of high temperature that adapts to material of sticky shape, it not only prevents to be heated material effectively and is worn out in process, and can reduce power consumption, reduces production costs.
In order to achieve the above object, the invention provides a kind of pair of roller dryer, it comprises drying roller, doctor blade device and inlet, and described drying roller is two and adjacent arrangement, described inlet is positioned at the top of two drying rollers, and the urceolus face of every drying roller all posts doctor blade device.
After adopting this structure, because two drying rollers only form single slurry tank each other, the precook time of slurry in slurry tank reduces, the slurry gelatinization time shortens greatly, avoided aging, be more suitable for α starch product manufacturing technique requirent, helped improving end product quality; Adopt two drying rollers simultaneously, the many forward and reverse transfer rollers of forming slurry tank have been removed, significantly reduce slurry to the sticking glutinous resistance of drying roller and roller extruding, the shear force to slurry, thereby reduced energy consumption, general finished product power consumption per ton can be reduced in 150 degree.Also, make every roller all become effective work roller owing to adopt two drying roller structures and all post doctor blade device at every drying roller urceolus face.Inlet directly places the top of two drying rollers, helps the even of continuous cloth and cloth.
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is the structural front view of a specific embodiment of a kind of pair of roller dryer of the present invention;
Fig. 2 is the left view of structure shown in Figure 1;
Fig. 3 is that A in the structure shown in Figure 1 is to view.
Two drying rollers 10 of Fig. 1, two roller dryers shown in Figure 2 are by supporting base 12 supportings, and supporting base 12 is installed on the frame 13, and supporting base 12 is four pairs can regulate supporting, can finely tune the gap of two drying rollers 10.As shown in Figure 3, supporting base 12 two ends have trimming bolt 14 respectively, trimming bolt 14 is formed screw thread pair with bolt block 15, can certainly adopt lead screw pair, has effect same, unclamp the set bolt of supporting base 12 and regulate trimming bolt after two drying rollers reach respective clearance, tighten set bolt again.Drive two drying rollers 10 by main motor reducer 1 by gear drive.Two drying rollers 10 all are one to be of a size of Φ 1000 * 3050, and operating pressure reaches the casting roller of 0.8MPa, chrome-faced, and casting roller can bear the ideal effect that HTHP reaches instantaneous gelatinization drying, can overcome the yielding defective of welding roller again.Two pairs of swivel joints that are connected and siphon pipe 2 pass a distolateral wall of drying roller, put in the tube of drying roller, for two drying rollers provide thermal source and carry out heat exchange by siphon pipe.It is adjacent and the inlet 9 slurry tank top that forms can be arranged in slurry two drying roller slurry tanks continuously equably to be arranged in two drying rollers 10, the controlling organization of its inlet is that inlet 9 is hinged on feed support 11 by oscillation bearing 8, feed straight-bar 7 one ends are hinged on the inlet 9, the other end then is hinged on the supply disk 5 prejudicially, feed rotating disk 5 is driven by motor for feeding 6, inlet, the feed connecting rod, the feed rotating disk is formed a crank and rocker mechanism, this mechanism is compact conformation not only, and the mutual motion between each parts is rotation, the resistance of motion is little, and fault rate is low; Feed rotating disk in this mechanism also can adopt corresponding constructions such as shaft-like crank.Two pairs of doctor blade devices 3 are close to the surface of drying roller 10, continuously to scrape the material film of being dried from the drying roller surface, adjusting screw(rod) and adjusting handle 4 are arranged on the doctor blade device 3, make it to be close to roller to regulate scraper pressure, scraper adopts the 65Mn steel plate to carry out Carburization Treatment, and its hardness is＞HRC58.
Another kind of embodiment as the inlet controlling organization, inlet 9 by be loaded on movably pulley on the feed support 11 on the crossbeam of feed support 11 along moving back and forth aspect the slurry tank length, pulley is driven by motor for feeding 6, and this mechanism can make inlet continuous feeding in slurry tank equally.Certainly inlet also can adopt corresponding manners such as pulp-hanging type, jet printing type, immersion except that adopting above-mentioned two kinds of embodiments.Equally, the gear drive that the transmission device of main motor-driven drying roller promptly can be above-mentioned; Also can adopt chain transmission, transmission devices such as synchronous cog belt.Therefore, the present invention is not limited to above-mentioned embodiment, no matter on its shape or structure, do any variation, and two adjacent drying rollers of all employings, the roller dryer of two pairs of doctor blade devices and inlet all drops within protection scope of the present invention.
