Technical field
The utility model relates to a kind of baking oven, and medicine particle drying when preparing specifically for health products is dried.
Background technology
We notice the structure improving relevant device always in the preparation process of health products, can ensure production efficiency and the quality of our health products like this; In the preparation, what the oven dry of its medicine particle was traditional is all the mode adopting heating hydrofuge to health products, and this mode is when reality uses, and power consumption is large, and temperature of exhaust gas is high, and the energy causes waste; The consecutive production efficiency of traditional relevant drying oven is lower.
Utility model content
Technical problem to be solved in the utility model is that, for above-mentioned deficiency of the prior art, provide a kind of medicine particle drying oven, its drying efficiency is high, energy-conserving and environment-protective, can continuous prodution efficiently.
The utility model solves the technical scheme that its technical problem adopts: medicine particle drying oven, comprises auger conveyor; Auger conveyor arranges charge door; Described auger conveyor is communicated with the position on the close top of drying casing side; Be provided with rotating shaft in described oven dry casing, drying baker external body corresponding to one end of rotating shaft is provided with the motor that drive shaft is rotated; Described rotating shaft is welded with several upset rod, dry bottom half and thermal insulation board is installed, the lower end of thermal insulation board is provided with promotion cylinder, the piston rod of promotion cylinder is provided with baffle plate, the below of drying casing is provided with conveyer belt, limiting cylinder is arranged on the right flank of drying casing, and the piston rod of limiting cylinder is provided with limiting plate, and air cooling equipment is arranged on the bottom of drying casing;
The opposite side of described oven dry casing is communicated with near the position on top and is provided with pipeline, and described pipeline is connected with vacuum trap, and dry on pipeline that casing leads to vacuum trap and be disposed with the second valve and sewage draining exit, vacuum trap top is provided with Butterworth Hatch; On the pipeline of described sewage outfalls setting below vacuum trap;
Described drying baker body periphery is enclosed with heat exchange jacket; The outlet of ethylene glycol storage tank connects the first valve successively by pipeline, pump and heat exchanger, and the far-end of this section of pipeline is communicated to described heat exchange jacket; Described heat exchange jacket is also communicated to ethylene glycol storage tank by return line.
As a kind of preferred embodiment of the present utility model, described upset rod is T-shaped; Described air cooling equipment is several fan composition.
Medicine particle drying oven described in the utility model, it has the following advantages:
1, the utility model adopts ethylene glycol as heating and cooling medium, open the first valve, ethylene glycol in ethylene glycol storage tank is pumped in plate type heat exchanger by pump, lead to liquid nitrogen by plate type heat exchanger to lower the temperature to ethylene glycol, ethylene glycol is passed into the heat exchange jacket of drying casing, complete the pre-freeze to material, pre-freeze is terminated, logical hot water heats up to ethylene glycol, equally by ethylene glycol being passed into the heat exchange jacket of drying casing, continue conversion ethylene glycol temperature, make the moisture in material complete distillation, reach freeze drying object; This drying mode of the present utility model makes material locate all the time at low ambient temperatures, removes moisture fast, effectively prevent material and degrades under hot and humid environment, effectively ensure that product quality, shorten arid cycle; Vacuum trap can also be realized to clean online simultaneously, reach splendid cleaning effect, still can carry out cleaning when not stopping production, shorten cleaning time, ensure dry vacuum.
2, logistics is stirred by upset rod by the utility model in above-mentioned material sublimation process, accelerates distillation efficiency and uniformity; Meanwhile, in order to ensure that high efficiency continuously is produced, the utility model is by auger conveyor convey materials, after drying completes, promote cylinder baffle plate is opened, material through tape transport, during conveying by air cooling equipment air-dry and cooling, simultaneously by the thickness of limiting plate restriction material, easy and simple to handle.
