Vacuum Spray Dryer

The Laboratory vacuum spray dryer is specially developed for thermal sensi-tive materials. The whole machine is compact and self-contained, and can run without any other facilities. One button start-up, large LCD touch screen operation, can adopt two operation modes of full automatic or manual moni-toring, which is convenient for operation and monitoring of experimental pro-cess, especially realizing instant drying of materials under low temperature conditions(50℃), providing extremely convenient and safe drying methods for heat sensitive materials, such as biological products such as enzyme preparation, active bacteria, and extracts of natural products of traditional Chinese medicine with high sugar content , high polymer materials that are not heat-resistant,materials that are vaporized in case of heat, etc.

TECHNICAL DATA

  • Rated  material  handling  capacity:1500ml  /h;

  • Minimum sample size:50ml (depending on the solid content of the  material);

  • Real time control  PID constant temperature control technology, heating tem-  perature  control  accuracy:±1  ℃;

  • Nozzle diameter:0.5mm,0.7mm,1mm,1.5mm,2mm  optional, and can be customized according to customer requirements;

  • Overall power:6kW 1380V;

  • Under the condition of low temperature  (minimum  50 degree), instant spray drying is completed. After drying, the moisture content is less than 1%. Under this drying condition, the substances which are easy to oxidize, volatilize and heat sensitive can well maintain the chemical structure and biological activity.

  • Vacuum degree-0.05-0.06Mpa;

  • Color LCD touch screen operation control, Chinese and English operation in- terface.

  • the spray head is located in the middle of the drying chamber, which can be used for parallel flow drying and countercurrent drying. The drying time can be extended or shortened according to the characteristics of the material, which is more suitable for heat sensitive materials.

  • Size:100*100*180cm


PRODUCT ADVANTAGES

  • The whole process of spray drying is completed in a vacuum environment. The instant drying of materials at low temperature(50C)is realized, which greatly reduces the drying temperature of materials and solves the problem of spray drying of thermosensitive materials.

  • Color touchscreen operation: heating temperature   PID  constant tempera- ture control, peristaltic pump feeding speed can be adjusted at any time.

  • Full automatic control: one button start, set the spray process parameters, display animation on the touch screen, and display the operation process clearly.

  • Manual control: if it is necessary to adjust the process parameters during the experiment, it is convenient to switch to the manual state, and the whole experiment process is dynamically displayed on the color touch screen (ani- mation).

  • Shutdown protection function: just press the stop button when shutting down, the machine will stop running immediately except for the fan, to ensure that the heating part of the equipment will not be burnt out due to misoperation (forced shutdown of the fan).

  • The machine has the function of misoperation protection. When the fan and heater switches are pressed in the wrong order, the machine will automatically remind to prevent the novice from damaging the machine by misoperation.

  • Built in imported oil-free air compressor, the particle diameter of powder spraying is normal distribution,the fluidity is very good, and the noise is very ow, which meets the  National  Laboratory noise standard.

  • A tomization structure of two fluid atomizing machine. The machine is made of high quality stainless steel, with  compact design, no need for accessory equipment, and convenient use.

  • Spray, drying, and collection system is made of high quality stainless steel.

  • For viscous materials, a nozzle cleaner  (through needle)is provided. When the nozzle is blocked, it will automatically clear and the frequency of through needle can be automatically adjusted.

  • In order to meet the user's requirements of adjusting various parameters in the experimental range, the real-time  PID  constant temperature control technology is adopted in the design of drying temperature control to make the temperature control in the whole temperature area accurate and the heating temperature control accuracy  is  at±1  ℃.
