The invention discloses a process for drying hemerocallis citrine by using a heat pump and hot air together. The process comprises the following steps: 1, selecting fresh hemerocallis citrine; 2, pretreating the hemerocallis citrine, namely, soaking, washing, putting into trays, steaming to remove the moisture, and cooling in air; 3, drying by using the heat pump and the hot air together; 4, cooling and detecting, namely, cooling to re-soften, and detecting; and 5, sub-packaging. The process has the beneficial effects that the energy consumption is low, the efficiency is high, the color, the flavor and the nutrient components of materials are effectively preserved, factory-like continuous operation is achieved, the production process is advanced, the procedures are simple, and the production period is short. |
