| titleOfInvention | ADSORPTION-CRYOGENIC APPARATUS FOR SUBLIMATION DRYING OF BIOLOGICAL MATERIALS |
| abstract | The utility model relates to the technique of freeze-drying and can be used in microbiological and other industries for drying cultures of microorganisms. The technical result of the proposed utility model is to simplify the design of the installation, to allow drying of pathogenic microorganisms in the field, and to shorten the drying cycle. The adsorption-cryogenic apparatus for freeze-drying biological materials contains a vacuum chamber made in the form of a glass with an axial hole in the bottom and a cover having an elastic ring seal and screw clamp, an adsorption-cryogenic vacuum pump made in the form of a pipe filled with a sorbent, one end of which has a plug, and the other open end is connected to the bottom of the cup coaxially made holes in it, the stand with slots for containers with dried material, placed in a vacuum chamber, and a unit for supplying nitrogen vapor to the vacuum chamber, the pipe with the sorbent being placed in the Dewar vessel, and the vacuum chamber in the neck of the Dewar vessel. The unit for supplying vapor to the vacuum chamber contains a cooling tube placed in the tube of the adsorption-vacuum pump along its axis, one end of which is passed through the pipe plug to the outside, and the other end is brought out through the wall of the glass of the vacuum chamber, a pipe located outside the glass of the vacuum chamber and elastically -elastic hose with pinch device, one end of which is connected to the cooling tube, and the other to the nozzle of the glass of the vacuum chamber. The sorbent can additionally fill the lower part of the vacuum chamber to the level of the stand with sockets, which will reduce the drying time of the biomaterial. As a sorbent, highly dispersed silica gel is used with a pore volume of up to 4.5 cubic cm / g, a specific surface area of up to 500 m 2 / g, a bulk density of 0.1-0.15 g / m 3 , and a particle size of up to 30 microns, which also reduce the drying time of the biomaterial. |
