Functional and Technical Analysis of Core Components of Laboratory Boiling Drying Machine
Date: 2025-12-18Read: 5
The laboratory boiling dryer is a pre-treatment equipment that uses hot air flow to boil wet granular materials, achieving efficient, uniform, and low-temperature drying. It is widely used in the fields of pharmaceuticals, chemicals, food, and materials science, especially for powders, particles, or crystalline samples that are heat sensitive, prone to clumping, or require rapid drying. The mild and efficient drying effect of the laboratory boiling dryer is derived from the precise collaboration of multiple functional modules.
1、 Fluidized bed chamber
Made of high borosilicate glass or 316L stainless steel, with transparent and visible design for real-time observation of material fluidization status; The bottom is equipped with a precision porous distribution plate (pore size 0.5-2mm) to ensure that hot air penetrates the material layer evenly, forming a stable "boiling bed", avoiding channeling or dead zones, and improving heat and mass transfer efficiency.
2、 Hot air system
Built in PTC ceramic heater or electric heating tube, combined with high-precision PID temperature control module, can stably control the inlet air temperature from room temperature to 150 ℃ (some models up to 300 ℃), with a temperature control accuracy of ± 1 ℃; The air volume of the fan is infinitely adjustable (usually 0-5m2/min), suitable for materials of different particle sizes and densities, to prevent blowing through or insufficient fluidization.
3、 Dust removal and exhaust gas treatment device
Top integrated bag or filter type dust collector (filtration accuracy ≤ 1 μ m), effectively intercepting the escape of fine powder and protecting the laboratory environment; Some models are equipped with condensation recovery or activated carbon adsorption units, which are suitable for drying organic solvent wet materials and comply with EHS safety regulations.
4、 Control system
Equipped with a touch screen human-machine interface, it can preset and automatically execute multi-stage programs of "heating constant temperature cooling"; Real time display of temperature, wind speed, running time and other parameters, and support data export to meet the requirements of GLP/GMP experimental recording.
5、 Auxiliary function module
Sampling port: A small amount of sample can be taken without stopping the machine to detect the drying endpoint;
Negative/Positive Pressure Switching: Adapt to different material characteristics to prevent dust overflow or oxidation;
Quick installation clamp design: easy to disassemble and clean, avoiding cross contamination.
