Description
Technical Field
[0001] The utility model relates to the technical field of spray drying, in particular to low-temperature nitrogen electrostatic spray drying equipment. Background Art
[0002] Spray drying equipment is a device that can complete drying and granulation at the same time. When the material needs to be dried, the operator will pass the high-temperature nitrogen into the drying cylinder through the air inlet pipe, and then put the material in from the feed port. At this time, the centrifugal sprayer atomizes the material to increase the contact area between the material and the high-temperature nitrogen, thereby drying the material. After drying, the material is discharged through the discharge port. And after the material is atomized and contacts with the high-temperature nitrogen, some organic solvent gas is easily generated.
[0003] In the prior art, the effect of drying materials by only atomizing the materials with a centrifugal sprayer or a pressure sprayer is not good, and the moisture on the materials is not easy to evaporate. At the same time, since the drying principle is to evaporate the moisture of small droplets on the materials with hot air, the temperature is high, which causes a large loss of the flavor or active ingredients of the materials. In addition, the traditional feeding method is to allow the materials to enter the drying tower by their own weight, resulting in a large amount of materials entering the drying tower at the same time. The instantaneous atomization may not allow a large amount of materials to be dried at the same time, thereby affecting the drying effect. Moreover, only performing a layer of drying in the drying tower will also result in poor drying effect. Utility Model Content

The instantaneous atomization may not allow a large amount of material to be dried at the same time, thereby affecting the drying effect, and only performing a layer of drying in the drying tower will also lead to poor drying effect.

A pumping pipe 31 connected to a feed port 33, and a pumping device 32 for controlling the pumping pipe 31 to transport materials, the separation mechanism 60 includes a separation tower 61 connected to the drying tower 20, a blower 64 connected to the separation tower 61, a filter tube 62 arranged at the center of the separation tower 61, a filter cartridge 63 located above the filter tube 62, and a discharge port 65 arranged at the bottom of the separation tower 61; the low-temperature nitrogen electrostatic spray drying equipment also includes a nitrogen pipeline 80 arranged above the drying tower 20, and the nitrogen pipeline 80 is used to provide nitrogen to the drying tower 20.
[0030] It can be understood that the utility model provides a nozzle 41 and an electrostatic generator 52 in the drying tower 20, wherein the electrostatic generator 52 is located below the nozzle 41, and a nitrogen pipeline 80 is provided on the drying tower 20, and a pumping pipe 31 connected to the feed port 33 of the drying tower 20 and a pumping device 32 connected to the pumping pipe 31 are provided. When the material needs to be dried, the pumping device 32 is started to intermittently transport the material to the drying tower 20 through the pumping pipe 31, so that the material is gradually dried, and a large amount of material is prevented from entering the drying tower 20 at the same time, resulting in poor drying effect.

Because the drying principle uses static electricity and inert gas, the flavor and active ingredients of the material are better preserved. At the same time, by setting a separation mechanism 60 connected to the drying tower 20, when the material is dried once by atomization and electrostatic field, it falls along the drying tower 20, and the blower 64 generates negative pressure in the separation tower 61 to suck the material from the drying tower 20 into the separation tower 61, and spirally descends along the separation tower 61. When the material falls to the bottom of the filter tube 62, the material falls through the discharge port 65 and is collected. The impurities or residual water vapor on the material will be sucked upward along the filter tube 62 and attached to the filter cartridge 63, so as to perform secondary drying and collection on the material.

When the material needs to be dried, the pumping pipe is started to intermittently transport the material to the drying tower through the pumping pipe, so that the material is gradually dried, and a large amount of material is prevented from entering the drying tower at the same time, resulting in poor drying effect. When the material enters the drying tower, the nozzle will spray inert gas to atomize the material, and then the electrostatic generator will apply an electrostatic field in the drying tower. Under the action of the electrostatic field, the polar moisture and non-polar solid of the material are Relative movement occurs between the state substances, so that the moisture tends to the surface of the droplets, and then the moisture on the material is more easily evaporated. Since the drying principle uses static electricity and inert gas, the flavor and active ingredients of the material are better retained. At the same time, by setting a separation mechanism connected to the drying tower, when the material is dried once by atomization and electrostatic field, it falls along the drying tower. The blower generates negative pressure in the separation tower to suck the material from the drying tower into the separation tower and spirally descend along the separation tower.
