Description

Technical Field

[0001] The utility model embodiment relates to the technical field of black soldier flies drying devices, and in particular to a black soldier flies rapid drying and preparation device. Background Art

[0002] Black soldier fly is a saprophytic insect. Its larvae and pupae are rich in essential amino acids and minerals and have a high fat content. It has been identified as an important feeding resource insect and has been applied and promoted in the production of animal protein feed and the conversion of poultry and livestock manure and domestic waste.

[0003] Black soldier flies need to be dried and processed before they can be used as feed. The drying equipment used is, for example, a black soldier fly drying device disclosed in Chinese patent application number CN202222044852.3, the specific content of which is: the air will be heated by multiple groups of electric heating tubes, and the heated air will be distributed to two groups of guide branch pipes through the guide main pipe, and then the hot air will enter the two groups of guide shells, and finally dispersed and sprayed downward through multiple groups of through holes, so as to evenly dry the black soldier flies in the drying tray. It has the following technical problems:

[0004] When drying the black soldier flies, since the black soldier flies are statically placed on the upper end of the drying tray, the temperature of the black soldier flies close to the drying tray is lower than that of the black soldier flies close to the through holes, making it difficult to dry the black soldier flies uniformly. Utility Model Content

[0005] To this end, an embodiment of the utility model provides a black soldier fly rapid drying preparation device to solve the problem in the prior art that black soldier flies are difficult to dry uniformly.

[0006] In order to achieve the above purpose, the embodiment of the utility model provides the following technical solutions:

[0007] A device for quickly drying and preparing black soldier flies comprises a drying box.

[0008] A lifting device for conveying black soldier flies is installed inside the drying box, and a limiting device for limiting the position of the black soldier flies is installed inside the drying box.

[0009] An auxiliary heat dissipation device is installed at the upper end of the drying box to facilitate heat dissipation.

[0010] The drying box includes a box body, a sealing door for closing the inner cavity of the box body is installed at the upper end of the box body, a heating tube for heating the inner cavity of the box body is installed at the upper end of the inner cavity of the box body, and a first annular buffer plate for slowing down the descending speed of black soldier flies is installed on the inner wall of the box body.

[0014] Furthermore, the lifting device includes a spiral blade for cooperating with a limiting tube to transport black soldier flies, and the spiral blade is located in the middle of the limiting tube. A rotating shaft for controlling the rotation of the spiral blade is installed in the middle of the spiral blade, and a motor for controlling the rotation of the rotating shaft is installed at the upper end of the rotating shaft.

[0015] Furthermore, the bottom end of the limiting tube is provided with a plurality of feed ports for conveying black soldier flies to the spiral blades, and the edge of the second annular buffer plate is provided with a plurality of second heat-conducting grooves for cooperating with the first heat-conducting grooves for circulating hot air.

[0038] The drying box 100 includes a box body 110, and a sealing door 111 for sealing the inner cavity of the box body 110 is installed at the upper end of the box body 110, and black soldier flies can be released into the inner cavity of the drying box 100 through the sealing door 111. A plurality of heat dissipation holes 120 for heat dissipation are opened at the upper end of the box body 110, and a heating pipe 130 for heating the inner cavity of the box body 110 is installed at the upper end of the inner cavity of the box body 110. A power line 131 is fixedly installed at the upper end of the heating pipe 130, and the power line 131 is connected to an external power source. When the black soldier flies need to be dried, the heat dissipation holes 120 heat the inner cavity of the drying box 100 through the transmission of electricity through the power line 131.

[0039] The inner wall of the box body 110 is installed with a first annular buffer plate 140 for slowing down the descending speed of the black soldier flies. After the black soldier flies are lifted to the upper end of the inner cavity of the drying box 100 by the lifting device 200, when the horizontal height of the black soldier flies exceeds the top height of the limiting tube 310, the black soldier flies fall from the upper end of the limiting device 300 to the upper end of the first annular buffer plate 140, and then slowly fall to the groove cavity of the second annular buffer plate 320 through the guidance of the first annular buffer plate 140, and so on and so forth, thereby increasing the drying time of the black soldier flies.

[0040] A plurality of first heat-conducting grooves 141 for circulating hot air are provided in the middle of the first annular buffer plate 140. A feed pipe 150 for conveying dried black soldier flies is installed at the lower end of the box body 110. A sealing plug is provided inside the feed pipe 150.
