Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a vertical drying device for preparing everlasting flowers. Background Art

[0002] Preserved flowers are made from fresh cut flowers such as roses, carnations, phalaenopsis, hydrangeas, etc., which are processed through a series of complex processes such as dehydration, bleaching, drying, and dyeing. Preserved flowers are almost the same as fresh flowers in color, shape, and feel. They retain the characteristics of fresh flowers, and have richer colors, more uses, and a shelf life of at least 3 years. They are the most ideal deep-processed flower products for floral design, home decoration, and celebrations.

[0003] The existing referenceable Chinese utility model patent with announcement number: CN210374368U discloses a drying box for everlasting flowers, including a drying box, a placement rack, a heat source chamber and a blower, one side of the drying box is connected to the box door by a hinge; the box wall of the drying box is a stainless steel layer, a heat insulation layer and a stainless steel outer shell layer from the inside to the outside; the inner wall of the drying box is symmetrically provided with a heat source chamber; the interior of the heat source chamber is provided with an electric heating wire; the outer wall of the heat source chamber is symmetrically provided with a plurality of exhaust hole groups; the placement rack is symmetrically provided with a plurality of L-shaped placement tables; the drying tray is placed on the L-shaped placement table; the bottom of the placement rack is fixedly connected to the bottom of the drying box by a supporting leg; the air supply end of the blower is connected to the heat source chamber through an air supply pipeline. The utility model has a high thermal energy utilization rate, effectively ensures that the heat is evenly distributed to the entire drying box, and the drying speed is fast and uniform, which is conducive to the discharge of moisture on the surface of the everlasting flowers.

[0004] The existing drying box is generally a rectangular structure. The temperature inside the box is raised by a heat source to dry the flowers. Due to the structure of the box, the temperature of the part inside the box close to the heat source rises faster than the part far from the heat source, resulting in different drying rates for the flowers, affecting the drying efficiency. Currently, the high-humidity air inside the drying box is removed by rotating the fan blades driven by a motor. This method cannot allow the internal airflow to remove the liquid solvent inside the drying box. Some of the liquid solvent will remain inside the drying box, affecting the drying quality.
