1working principle
This dryer under the vacuum condition, carries on the heating in the jacket by the steam or the hot water, is directly through the hot energy in the shell inside and the wet materials contact, depends on the tube body rotation, tumbles unceasingly the material. After the material heat absorption evaporates the steam, extracts outside continuously the tube through the vacuum pump after the steam exhaust pipe, thus speeds up the material the drying velocity, tumbles unceasingly along with the material, achieves the material even dry goal. This equipment and the heating area same general drying box and the kang type heater compares, the dry thermal efficiency may become time of enhancement, and can improve the work condition and the labor intensity.
2Use of    GL  RCVD
This factory production dryer is one kind of multipurpose machine, is suitable in powdery or granular material vacuum drying and the mix, also is suitable specially in has the following request material.
    1). Cannot accept the high temperature;
2).  Easy to oxidize;
3). Has the strict request to the crystallization shape;
4). Has the strict limit to the metallic ion content;
5). Requests the remaining volatile matter content to be extremely low;
6). Dry when discharges the steam must recycle.
The material the dry merit may evaporate under the vacuum for the volatile matter under the low temperature, may be suitable hotly sensitive, the hatred oxygen class material is dry, in the shell of tank the glass lining, has smoothly, clean does not cake characteristic of the material
Uses this aircraft to be possible to arrange several operation sequences in a machine completes successively. Therefore can save the equipment, reduces the operating time, saves the energy, reduces the labor intensity, reduces the leak and the impurity mix opportunity, thus may obtain the high-purity product.
1)Design pressure:
Vessel inside:-0.1Mpa(vacuum)     Jacket<0.1Mpa
2)Max.working pressure:
Vessel inside: -0.1Mpa(vacuum) jacket<0.1Mpa
3)Medium: Organic powder material (PH<12)in the shell, water or vapor in the jacket.
4) Maximum temperature: 140℃ (for example when user request oil heating may be bigger than with design relation temperature 140℃)
5)Shell of tank rotational speed: 4~8 revolution of/minutes (when user request may match velocity modulation electrical machinery)
                       4Operation specification of dryer   
1)The closure puts the material hole cap
2)Opens feeds the lid, starts to feed, feeds the volume not to have to surpass the nominal volume 50%.The material does not have to smuggle has massive hard.
3)The closure feeds covers
4)Closes the power switch, the shell of tank starts to revolve.
5)On the opening pumping air pipeline vacuum valve, in the pot namely implements the negative pressure operation.
6)The opening pumping air heating with the steam valve, (or hot water valve, cooling water valve), must pay attention, when this aircraft heating or cooling, should carry on slowly. Heat resistant emergency cold impact 110℃, thermal shock 120℃.According to the pot in the material granularity, the water content and the permission heating temperature, should use the suitable elevation of temperature speed, in the clamp cover steam pressure is highest does not have to surpass 0.1Mpa.
7)In after the pot the material dry mix completes, the cut-off steam and the aspirator line, then pass the cooling water to the clamp cover, waits the material to cool after the specified temperature, presses the electrical machinery “the stop” the button, causes to put the position which the material mouth changes to needs.
8)Turns in the exhaust pipeline the dump valve, causes the shell of tank interior connection atmosphere.
9)Turns on lathe the pine to put the fastening installment which the material covers, the rotation puts the material valve cover, then puts the material.
10)materials dump the shell of tank completely, should sweep clear in the pot the residuum, and closes puts the material hole cap.
11)In the machine operation process wants when carries on the middle sampling observation, should according to the 7th stipulation cause the machine first to stop, then presses 8, 9 stipulations again, opens puts the material hole cap to carry on the sample.After the sample finished, the closure puts the material hole cap, should according to 4, 5, 6 and so on the strip stipulations drive.
