Product features double cone rotary vacuum dryer is a mixed double cone rotary vacuum dryer, vacuum drying in one of the drying equipment. Vacuum drying process the material to be dried is placed in a sealed cylinder body with a vacuum system was evacuated along with the continuous heating of the material to be dried, the moisture inside the material through a pressure difference or differential concentration of the dispersion to the outer, water molecules (or other non-condensable gas) to obtain the appearance of kinetic energy in the material to meet after overcoming another attraction between molecules dispersed into the low-pressure space of the vacuum chamber is vacuum pumped and finished with solid parting. So, double cone rotary vacuum dryer performance at properties: (1) vacuum drying process, the pressure cylinder body has been lower than the atmospheric pressure, the number of gas molecules, low density, low oxygen, thus drying simple oxidation drugs, reduce material contamination time. (2) Because the temperature and moisture vapor pressure is proportional to the vaporization process, so the vacuum drying, the material in the moisture vaporization at low temperature can reach the low-temperature drying, particularly suitable for the production of heat-sensitive materials have drugs. (3) vacuum drying to eliminate the appearance of atmospheric air drying outer hardening prone, it is because a large pressure difference between the inner and outer vacuum dried material at a pressure gradient effect, the water quickly moved appearance, not rendered appearance hardened. (4) Because the vacuum drying, the material between the internal and external temperature gradient is small, because the effect of reverse osmosis so moisture can be moved separately and collected, separated overcome the appearance of hot air drying occurred. 1 double cone rotary vacuum dryer operating procedures, before driving to view: a, open the vacuum view, convergence at the pipeline, stuffing is not leaked into, a gate seal is not outstanding, vacuum gauge reaction is not active. b, open cooling water valves View convergence at the heating pipes, the stuffing is not a leak, pressure gauge reaction is not active. c, view the cabinet each appearance, buttons, lights are not normal, to view the grounding line is not outstanding, with or without leakage, short circuit representation exists. d, in the oil cup filled with grease, starter motor empty job, listen to the noise is not normal, if not normal, you should check out the source of the noise, and to be ruled out. 2, will be required to participate in the container dry material (powder, fine granules, slurries selection of vacuum feed), and then closing the feed hole cover. 3, row after closing the vacuum valve, open the vacuum pump, so that the negative pressure within the drying vessel (600 - 755 mmHg). 4, close the power switch, start the motor, press the button work, start drying machine rotation job. 5, the heating medium valve open, allowing the heating medium into the drying vessel dissection, measurement test according to the process needs. 6, after the completion of drying, heating medium valve closure first, then write the cooling water into the sandwich, until the material is cooled to room temperature, the suspension is evacuated. Vacuum exhaust valve open, closed motor, suspension dryer rotation, open the hole cover the material.
