Embodiment 1
[0040] In order to solve the technical problem that the freeze-dried biopesticide powder loses its activity due to the temperature rise of the material, mold or tableting wheel due to extrusion when the freeze-dried biopesticide powder is compressed or punched, as Figure 1 to Figure 12 As shown, the following preferred technical solutions are provided:
[0041] A kind of production equipment of freeze-dried biopesticide effervescent granules, comprising,
[0042] Extrusion device 1, it is used for inputting powdery raw material and outputting bar-shaped raw material; And,
[0043] Granulating device 2, which is used to make strip raw materials into granules or flakes;
[0044] It also includes a refrigerant covering device 3 arranged between the output end of the extrusion device 1 and the input end of the pelletizing device 2, and the refrigerant covering device 3 is used to cover a layer of refrigerant on the strip raw material.
[0045] Specifically, the granulation devi...

[0051] In order to solve the technical problem of how to extrude powdery raw materials to form strip raw materials, such as Figure 1 to Figure 5 As shown, the following preferred technical solutions are provided:
[0052] Extrusion device 1 comprises,
[0053] The first extruding cylinder 1a, the first extruding cylinder 1a comprises the first feeding section 1a1 and the first extruding section 1a2 connected coaxially, the first feeding section 1a1 is a cylindrical shape, and the first extruding section 1a2 is In the shape of a cone, the diameter of the first extrusion section 1a2 shrinks away from the first feeding section 1a1, the first extrusion section 1a2 faces the input end of the pelletizing device 2, and the middle end of the first feeding section 1a1 is provided with a second a feed port 1a3; and,
[0054] The first screw rod 1b is rotatably installed inside the first extrusion barrel 1a, the first screw rod 1b extends from one end of the first extrusion barrel 1a ...
Embodiment 3
[0077] In order to solve the technical problem of how to cover a layer of dry ice on the surface of strip raw materials, such as Figure 9 to Figure 12 As shown, the following alternative technical solutions are provided:
[0078] The refrigerant covering device 3 includes an electrostatic powder coating machine 3f, and the output end of the electrostatic powder coating machine 3f faces between the output end of the extrusion device 1 and the input end of the granulation device 2 .
[0079] Specifically, electrostatic powder spraying machine 3f adopts HX-800 electrostatic powder coating machine, which uses the principle of electrostatic spraying to spray the workpiece. The spraying machine is equipped with a powder electrostatic spray gun, a controller and a small powder supply system. The electrostatic powder The spraying machine 3f effectively coats the dry ice powder on the strip material through the control of static electricity and aerodynamic force, and achieves complete...
