Abstract
Present invention discloses a healing sponge drying process, which is characterized in that a material is firstly subject to centrifugal dewatering, the moisture content at an early stage is greater than 90%, the temperature of hot water in a hot water tank is 50+/-5 DEG C, the pressure in a vacuum drying oven is 0.02Mpa, the drying time is less than 3 hours, a drying box is in an intermittent operation and can obtain vacuum through a vacuum pump; the pressure in a buffer tank is 0.002Mpa, the drying time is greater than or equal to 6 hours, a heating medium in the drying box is hot water heated by a coil pipe in the hot water tank and is cyclically used through a hot water pump. The healing sponge drying process provided by the invention has the beneficial effect that through controlling the moisture content at the early stage, the drying time of the drying box is decreased; and the through vacuum processing of the drying box, the heating effect of a hot water coil pipe is enhanced, and thus the energy conservation and the consumption reduction are realized.
Description
Technical field
The present invention relates to a kind of drying process, especially a kind of healing sponge drying process.
Background technology
The healing sponge is to be raw material with the marine organism extract, has efficient hemostasis, promotes the curable product of healing.Because of product thermal sensitivity is strong, outward appearance, water imbibition etc. is had relatively high expectations.Existing drying means has through drying box, drying room technology and carries out drying, but because not matching of drying process can not be satisfied its specification requirement, and energy consumption is high, efficient is low.
Summary of the invention
The present invention is directed to the deficiency of prior art, a kind of healing sponge drying process is provided, cooperate equipment such as square vacuum drying chamber, realize dry healing sponge.
For realizing above technical purpose; The present invention will take following technical scheme: healing sponge dried material is at first through centrifugal dehydration; Initial stage water content＞90%; The hot water temperature is 50 ± 5 ℃ in the boiler, and pressure 0.02Mpa, drying time are intermittently operated less than 3h, drying box, and obtain vacuum through vavuum pump in the vacuum drying chamber; Surge tank pressure 0.002Mpa, drying time >=6h, drying box heat medium are through boiler inner coil pipe heated hot water, and recycle through heat-exchanger pump.
The present invention is through control initial stage water content, reduces drying box drying time; Through the application of vacuum of drying box, strengthen the hot-water coil pipe heats, improve the thermal efficiency, reach energy-saving and cost-reducing.
Description of drawings
Fig. 1 is the healing sponge drying technology process sketch map of invention;
Wherein, 1, drying box 2, heat-exchanger pump 3, boiler 4, surge tank 5, vavuum pump.
The specific embodiment
As shown in Figure 1, healing sponge dried material according to the invention is at first through centrifugal dehydration, and initial stage water content＞90% reduced drying box drying time; The hot water temperature is 50 ± 5 ℃ in the boiler 3, and pressure 0.02Mpa, drying time are intermittently operated less than 3h, drying box 1, and obtain vacuum through vavuum pump 5 in the vacuum drying chamber 1; Surge tank 4 pressure 0.002Mpa, drying time >=6h, drying box 1 heat medium are through boiler 3 inner coil pipe heated hot water, and recycle through heat-exchanger pump 2.The final products water content:＜14%, temperature of charge: 35 ± 2 ℃.
Claims (2)
1. a healing sponge drying process comprises drying box, boiler, and said technology is at first through centrifugal dehydration with material; Initial stage water content＞90%, dry through drying box again, drying box also obtains vacuum through vavuum pump; The drying box heat medium is through boiler inner coil pipe heated hot water, and recycles through heat-exchanger pump, and the hot water temperature is 50 ± 5 ℃ in the boiler; Pressure 0.02Mpa in the vacuum drying chamber, drying time is less than 3h, surge tank pressure 0.002Mpa.
2. according to the said healing of claim 1 sponge drying process, it is characterized in that said drying box is intermittently operated.
