1. the Herba Melissae officinalis dewatering of the Herba Melissae officinalis essential oil processed of can holding concurrently comprises and utilizes the closed drying machine that Herba Melissae officinalis is carried out bake drying dehydrating step, characterized by further comprising following steps:

  • Water vapour is collected step, and at the venting port connection one water vapour collector of described closed drying machine, nationality is to collect the water vapour that produces in the Herba Melissae officinalis bake drying dehydration;

    The water vapor condensation step connects a closed condensate water recovery device at described water vapour collector, and nationality reclaims the water vapour that described water vapour is collected collection step with condensation;

    The ultrafiltration membrance filter step connects a ultrafiltration membrane filter device at described closed condensate water recovery device, and the molecular weight cut-off of the ultra-filtration membrane in the water of condensation that nationality reclaims to filter described water vapor condensation step condenses, described ultrafiltration membrane filter device is 1000;

    The nanofiltration membrane filtration step connects a nanofiltration membrane filtration unit at described ultrafiltration membrane filter device, and nationality filters rear ultrafiltration through liquid to filter described ultrafiltration membrance filter step, and the molecular weight cut-off of the nanofiltration membrane in the described nanofiltration membrane filtration unit is 500;

    The reverse osmosis concentration step, connect a reverse osmosis membrane apparatus at described nanofiltration membrane filtration unit, nanofiltration after nationality filters with concentrated described nanofiltration membrane filtration step is through liquid, and the concentrated solution after described reverse osmosis membrane enrichment step is concentrated is the Herba Melissae officinalis essential oil, and seeing through liquid is the smart dew of Herba Melissae officinalis.
