Description

Technical Field

[0001] The utility model relates to the field of dehydration equipment, in particular to a low-temperature dehydration and concentration device for traditional Chinese medicines with evaporation type. Background Art

[0002] Modern drying technology methods: mainly hot air drying, solar energy drying, far infrared drying, microwave drying, vacuum freeze drying, and high voltage electric field drying.

[0003] Hot air drying method: that is, blowing hot air into the oven or drying room, so that the moisture inside the Chinese medicinal materials is heated and escapes, and is taken away by the flowing hot air to break the balance of hot and humid air. Using coal, electricity or steam as the heat source, the commonly used equipment for hot air drying of Chinese medicinal materials includes box dryers, mesh belt dryers, tunnel dryers and vibrating fluidized bed dryers.

[0004] Hot air drying equipment has low cost, less time consumption, high efficiency, is not restricted by weather, can kill insects and prevent mildew, and has controllable temperature. It is suitable for drying most Chinese medicinal materials, such as: Pueraria lobata slices, wolfberry, red dates, honeysuckle, longan, Panax notoginseng, hawthorn, Schisandra chinensis, etc. 02 Solar drying method refers to the material to be dried directly absorbing solar energy or air heated by solar air collectors for convective heat transfer. After the material surface obtains heat energy, it is transferred to the inside of the material. The water diffuses from the inside of the material in liquid or gaseous form, passes through the material layer to the surface, and then diffuses into the hot air flow through the air film on the surface of the material. Through such a heat and mass transfer process, the material is gradually dried. The color and other properties of Chinese medicinal materials processed by solar drying method are well maintained, and it has the advantages of high drying efficiency, less drying time, less loss of Chinese medicinal materials, avoidance of secondary pollution of Chinese medicinal materials, as well as low drying cost, energy saving and environmental protection.

[0005] At present, a Chinese patent with publication number CN103960604A discloses a pure natural low-temperature baked celery powder and a preparation method thereof, which comprises screening, rooting, washing, leafing, blanching and dehydrating fresh celery, dividing the celery into leaves, twigs and celery stalks, blanching them in boiling salt water ≥95°C until they are translucent, then taking them out for dehydration and slicing; vacuum baking the dehydrated celery leaves, twigs and cut celery slices at a constant temperature of 50-60°C using a low-temperature baking device to process them into cooked dry celery, and sterilizing the baked and stirred cooked dry celery, and then grinding them into celery powder with a powder fineness of ≥120 meshes using a pulverizer.

[0006] Although this pure natural low-temperature baked celery powder and its production method neutralize the cold medicinal properties of celery and maintain the original flavor, nutritional components and good color of celery, the powder particles have a microscopic porous structure and have good rehydration properties. It can be directly mixed with boiling water for long-term consumption and can also be used as an ingredient in food, beverages, and traditional Chinese medicine. The baked dried celery can be eaten directly after sterilization, but it cannot solve the problem of high energy consumption of dehydration of traditional Chinese medicine. Summary of the invention
