Single-cone drier for feeding liquid continuously

Abstract

The invention discloses a single-cone drier for feeding liquid continuously. The single-cone drier comprises a conical drier body, wherein a stirrer is arranged inside the drier body, and is driven by a motor through a spindle; the drier is provided with a liquid-flow type predrying continuous feeding device; the continuous feeding device comprises two parts, namely a liquid-flow structure and a predrying structure; the liquid-flow structure is arranged on a feed opening of the drier body, and comprises a feeding barrel; the lower part of the feeding barrel is communicated with a liquid flow path stretching into the drier body through a valve; a plurality of branch tubes are inwardly arranged in the liquid flow path; and a plurality of small liquid-flow holes are formed in the lower side of each branch tube and corresponding to the predrying structure. By adopting the single-cone drier for feeding liquid continuously, for solid state feeding of materials, solvation of the materials due to physical, chemical reactions can be avoided, and then the material huddle into blocks can be avoided; for liquid state direct feeding of materials with poor heat penetration capacities, lumping solidification and wall-hanging coaking in the drying process can be avoided; and moreover, the application range of the single-cone drier can be greatly expanded, and emission of atmospheric pollutant can be greatly reduced.

Description

technical field [0001] The invention relates to a single-cone drier, in particular to a liquid continuous feeding single-cone drier. Background technique [0002] The applicant's patent CN 201417061Y discloses a high-efficiency multi-purpose single-cone dryer, which includes a single-head cone conical body composed of a heat-insulating layer and a heating layer. There is a heat medium inlet and a heat medium outlet connected to the outside, and a screw propulsion stirring paddle is arranged in the body, and the stirring paddle is driven to rotate by a motor arranged on the top of the body. The whole dryer has the characteristics of uniform heating of materials, high thermal efficiency, fast drying speed, high drying quality, convenient feeding and discharging, cleaning and disinfection, which greatly facilitates the drying of materials in the pharmaceutical process.

AI Technical Summary

Problems solved by technology

[0003] In the actual pharmaceutical process, there are many physical properties of industrial products to be dried, and the scope of application of the above single-cone dryer is very limited. If there is solid feeding, it will be physically dissolved and chemically dissolved during drying, and recrystallized into agglomerates; there are liquids Feeding, and the material has high water content, high viscosity, and poor heat penetration, such as traditional Chinese medicine extract

The above materials cannot be directly introduced into the dryer for drying, but can only be dried by using traditional common drying techniques and equipment, such as disc hot air oven, spray dryer, boiling dryer, vacuum belt dryer, not only The drying efficiency is low, and the final drying effect is not ideal, and there are problems of material pollution and air emission exceeding the standard
