Description

Tiltedly change the multipurpose vacuum drier

The utility model relates to a kind of oblique commentaries on classics multipurpose vacuum drier.

At present, still do not have the energy-conservation dynamic vacuum drying machine that maximizes, particularly have 10～90 ℃ of efficient cryogenic performances, meet the dynamic vacuum drying machine of GMP (GNP).Because of there not being this class drying equipment, many large-scale production contain the synthetic drug drying of organic solvent, have to utilize hot-air direct-heating type drying equipment, and not only energy consumption is big for this, and the organic solvents of preciousness are taken away with air tail gas in a large number, and having influenced environment has increased production cost again.And to lean on the production of hot blast tunnel type baking oven the dehydrated vegetables owner, and exist drying time long, energy consumption reaches shortcomings such as weak flavor greatly, and its outlet also has only the vacuum and low temperature of employing quick drying apparatus.Existing unique dynamic vacuum drying machine is a double conic rotary vacuum dryer, belong to chuck hot type structure, its heating surface (area) (HS does not increase with holding the ratio that enlarges during maximization, by the back heating surface (area) (HS that maximizes is seriously lacked of proper care with the ratio of volume, undeserved reputation capacious is arranged on foot.Doing less than 100 ℃ can only to adopt the heating of hot water sensible heat when dry because of double conic rotary vacuum dryer again, heat drying efficient is very low, more becomes to reducing after the maximization.

The utility model purpose be overcome produce heating surface (area) (HS when existing bipyramid rotary dynamic vacuum drying machine maximizes and volume out of proportion, low temperature drying can only provide a kind of blanching, flash distillation chilling, dipping baste and vacuum dehydrating at lower temperature several work oblique commentaries on classics multipurpose vacuum drier that supplies the dynamic drying of medicine vacuum and low temperature and make dehydrated vegetables with the shortcoming of hot water heating.

Technical solutions of the utility model are: it by exhaust tube, exhaust tube sealing, top roller, charge door, roller roller, the filter of bleeding, interior heating plate, heating jacket, the disinfection steam mouth of pipe, discharging opening, Low Temperature Steam generator, disinfection steam pipe, steam condensation water pipe, steam cross over pipe, end axle chain wheel, end rotating shaft, base bearing,, rotation steam joint and driving machine constitute; On roller roller and base bearing, cylindrical shell center line and horizontal line are 45 °～60 ° angles and tilt the cylindrical shell of being made up of interior heating plate and heating jacket by top roller and end shaft support, and the inclination cylindrical shell drives sprocket wheel by driving machine and rotates.Its operating feature is that pressure is that 0.1～0.2NPa primary steam removes the Low Temperature Steam generator through end rotating shaft, and 10～90 ℃ of low temperature saturated vapors that produced enter heating jacket, and enter heating plate in each by chuck.The Low Temperature Steam condensed water is subjected to gravity and potential difference effect, still loops back in the Low Temperature Steam generator in rotation.The primary steam condensed water that produces in the heating tube of Low Temperature Steam generator, then depended on pressure is discharged through end rotating shaft and rotation steam joint.

Medicine and vegetables are fried with cylindrical shell rotation and at interior heating plate and movingly turn over mixedly down, be heated turning over constantly contact in mixing with heating surface, the interior moisture content of the thing that is dried vacuum with heat rapid evaporation drying under the double action.When doing the vegetables pre-treatment, can open the effective live (open) steam people of sterilization evil germicide vapor blanching water and carry out blanching, and then can carry out vacuum suction after taking out blanching water, make residual hot water and vegetables carry out the flash vaporization chilling, reach a large amount of evaporations of moisture content and vegetables cooling with the shortest time, reduce vegetables and make destruction color and luster and nutrition because of being subjected to high temperature.Change vacuum dehydrating at lower temperature at last over to.

10～90 ℃ of Low Temperature Steam heating do not exist the heat medium out temperature poor, and the each point temperature is even.In cylindrical shell, insert heating plate, change chuck hot type maximization pattern, still can keep the proper ratio of heating surface (area) (HS and volume after the maximization, similar rate of drying and efficient when still having miniaturization.Interior heating can not be dispelled the heat to the external world, so unique radiation loss spy who influences this drying machine thermal efficiency is little, the thermal efficiency of maximization drying machine reaches more than 90%.

In the utility model, charge door, used hole when the discharging opening double as goes into to clean, meet GMP (GNP) requirement on the structure.But this drying machine is the then recyclable various organic solvents that evaporate behind the peripheral hardware tail gas cooler condenser still.Also but peripheral hardware aspirates out hot water or dipping baste facility, then can make vegetables blanching, flash distillation chilling, dipping baste and vacuum dehydrating at lower temperature multipurpose.This drying machine is applicable to dry usefulness such as medicine, various bioengineering product, medicinal material, chemical industry and food.It is the ideal equipment that substitutes the hot blast tunnel baking oven of traditional double conic rotary vacuum dryer or alternative dehydrated vegetables industry.

The utility model embodiment is described further in conjunction with the accompanying drawings.
