Description

Technical Field

[0001] The invention relates to the technical field of material drying, and in particular to a cyperus oleifera spray drying device and a method. Background Art

[0002] Cyperus oleifera, also known as tiger nut, is a nutritious crop rich in oil, protein, dietary fiber and minerals. Cyperus oleifera is usually processed into powder. The specific processing technology includes raw material soaking, raw material crushing, pulping, homogenization, spray drying, cooling and packaging, among which spray drying is one of the most important steps.

[0003] The cyperus rotundus is pre-treated by washing, peeling, etc., and then ground, soaked, etc. to make a cyperus rotundus wet liquid. Then, the cyperus rotundus wet liquid needs to be heated to a certain temperature before entering a spray drying tower to quickly evaporate water. The heated liquid is then sent into the spray drying tower through a high-pressure pump, and fine droplets are formed at the top of the tower through a rotary atomizer or a nozzle. At the same time, hot air is introduced into the spray drying tower. Under the action of the hot air, the cyperus rotundus wet liquid quickly evaporates water to complete drying. However, when the existing spray drying tower discharges the dried hot air, due to the small aperture of the exhaust hole and the filter cloth on the exhaust hole is prone to clogging, the efficiency and effect of the hot air discharged from the exhaust hole are not ideal, resulting in the hot air being easily discharged from the discharge port, and the hot air discharged from the discharge port is easy to blow away the dried cyperus rotundus material, which is not conducive to the aggregation of the cyperus rotundus material, and the cyperus rotundus material is prone to over-drying.

[0044] See also Figure 5 and Figure 7 The filtering mechanism 53 includes a rotating ring 531 rotatably connected to the lower end of the conical tube 52 and having a conical structure. The lower end of the rotating ring 531 is rotatably connected to the upper end of the support ring 55.

[0046] During specific operation, the rotating rod 611 rotates while driving the cylindrical rod 5361 to rotate. The cylindrical rod 5361 drives the rotating ring 531 to rotate through multiple connecting strips 5362. The rotating ring 531 drives multiple filter screens 533 to rotate. At the same time, the rotating ring 531 drives the second scraper bar 534 and the third scraper bar 535 to rotate. The rotating second scraper bar 534 can scrape off the dried oil bean paste material that falls on the conical tube 52, and the rotating third scraper bar 535 can scrape off the dried oil bean paste material that falls on the outer surface of the support ring 55, ensuring that the oil bean paste material is fully dropped and greatly reducing the waste rate of the oil bean paste material.

[0047] See also Figure 5 and Figure 7 The scraping mechanism 54 includes a support plate 541 installed on the inner wall of the drying tank 1, and a scraping strip 542 is installed at one end of the support plate 541 away from the inner wall of the drying tank 1. The scraping strip 542 is in contact with the outer surface of the rotating ring 531, and a brush structure (not shown in the figure) is provided at one end of the scraping strip 542 away from the support plate 541.

[0048] During specific operation, the rotating ring 531 drives multiple filter screens 533 to rotate. The filter screens 533 are made of metal and have a high mesh count. The rotating filter screens 533 are in contact with the scraping strips 542. The scraping strips 542 drive the brush structure provided thereon to continuously scrape the outer surface of the filter screens 533, thereby avoiding clogging of the filter screens 533 and ensuring that the hot air after drying can pass through the multiple filter screens 533 in large quantities during the drying process and enter the conical tube 52, and then enter the cyclone separation equipment through the intake pipe 51, thereby discharging the hot air.

[0049] See also Figure 5 , Figure 6 , Figure 8 and Fig. 9 The cyperus oleifera spray drying equipment also includes a knocking device 7, which is connected to the driving mechanism 61 and is located below the supporting mechanism 56.

[0051] During the specific operation, the rotating rotating rod 611 drives the rotating rod 71 to rotate, and the rotating rod 71 drives the first scraper 74 to rotate through the connecting column 73. The first scraper 74 scrapes the conical inner wall of the bottom of the drying tank 1, so that the dried oil bean paste material that falls on the inner wall of the bottom of the drying tank 1 falls into the discharge pipe 4. At the same time, the rotating rod 71 drives the rectangular frame 721, the knocking rod 723, and the right-angled triangle block to rotate with the rotating rod 611. During the process of the inclined surface on the right-angled triangle block contacting with the fixed column 562 and continuing to rotate, the right-angled triangle block will be subjected to a downward pushing force, and then the right-angled triangle block drives the rectangular frame 721 slides downward along the rotating rod 71 and stretches the connecting spring 722. At the same time, the right-angled triangle block drives the knocking rod 723 to move downward. When the right-angled triangle block is separated from the fixed column 562, the stretched connecting spring 722 is reset and drives the knocking rod 723 to reset upward through the rectangular frame 721. The knocking rod 723 knocks the fixed column 562. The fixed column 562 transmits the vibration force generated by the knocking to the support ring 55, the rotating ring 531 and the conical tube 52 through the supporting tray 561, and further shakes off the oil bean paste material that falls on the support ring 55, the rotating ring 531 and the conical tube 52.

During operation, the gas heater is started, and the gas heater injects hot air into the air inlet pipe 33. The air inlet pipe 33 injects hot air into the sprayer 31. At the same time, the wet cyperus rotten bean liquid is injected from the container into the feed pipe 32 through the existing pump body. The wet cyperus rotten bean in the feed pipe 32 enters the sprayer 31. The sprayer 31 atomizes the wet cyperus rotten bean and injects it into the drying tank 1. The hot air dries the atomized wet cyperus rotten bean. The dried cyperus rotten bean material falls to the intermediate The support ring 55, the rotating ring 531 and the conical tube 52 are vibrated intermittently, and the second scraper 534 and the third scraper 535 are rotated at the same time to scrape the outer surfaces of the conical tube 52 and the support ring 55, so that the oil bean paste material is effectively separated from the conical tube 52 and the support ring 55, and the remaining small part of the hot air in the drying tank 1 can also drop the dried cyperus rotundus material, and blow the cyperus rotundus material to the bottom of the drying tank 1, and the rotating spiral plate 62 drops the dried cyperus rotundus material, and the cyperus rotundus material enters the discharge pipe 4 and then enters the collecting device, until all the cyperus rotundus wet material liquid is completely dried, and the drying is completed.
