Spray drying system

Abstract

The invention discloses a spray drying system. The spray drying system comprises a spray drying tower, wherein the top part of the spray drying tower is connected with a hot air system; a material outlet in the bottom part of the spray drying tower is connected with a first-stage cyclone separator and a second-stage cyclone separator through a material outlet pipeline; a first draught fan is connected to a pipeline, which is close to one end of the first-stage cyclone separator, between the first-stage cyclone separator and the spray drying tower; exhaust pipelines arranged at the top parts of the first-stage cyclone separator and the second-stage cyclone separator are connected with a second draught fan through a pipeline after being connected; material outlet pipes arranged at the bottom parts of the first-stage cyclone separator and the second-stage cyclone separator are connected with a material inlet in the top part of another cyclone separator through a pipeline after being connected; an air inlet in the cyclone separator is also connected with the first draught fan through a pipeline; a material outlet pipeline arranged at the bottom part of the cyclone separator is connected with a mixing machine, a screening machine and a weighing and packaging machine in sequence through two branch pipelines. According to the spray drying system disclosed by the invention, automatic conveying of materials is realized, and the cleanliness of the materials is ensured.

Description

technical field [0001] The invention belongs to the technical field of drying equipment, and in particular relates to a spray drying system. Background technique [0002] Spray drying is a method of systematic technology applied to material drying. It has been widely used in chemical, food, pharmaceutical and other industries. In the existing spray drying technology, after the material is quickly dried in the spray drying tower, it is continuously fluidized and dried through the fluidized bed, and discharged from the outlet of the fluidized bed after meeting the required requirements, and finally weighed after sieving. Heavy packing. [0003] In the existing spray drying system, the discharge from the bottom of the spray drying tower and the cyclone separator is collected manually with plastic bags and woven bags, and then manually transported to the mixing gold operation platform, and then manually put the materials into the mixing Machine, manual operation process will i...

Problems solved by technology

[0003] In the existing spray drying system, the discharge from the bottom of the spray drying tower and the cyclone separator is collected manually with plastic bags and woven bags, and then manually transported to the mixing gold operation platform, and then manually put the materials into the mixing machine, the material will inevitably be scattered during the manual operation process, resulting in yield loss

The whole process requires a lot of manual operation, and the amount of manual labor is large. Moreover, due to the fine particles of the material, dust is generated during the feeding process, which increases the difficulty of sanitation and cleaning for employees, and does not meet the requirements of clean production; the existence of dust also increases occupational hazards. ; Dust falling and accumulating may easily cause dust explosion and fire accidents

In addition, it is difficult to clean the material conveying pipes of the original equipment, especially the air induction pipes cannot be cleaned
