Controller, the controller automatically adjusts the constant temperature and humidity in the drying room.

Adopt above-mentioned drying room to dry honeysuckle method as follows:

The water content of honeysuckle is medium to high, and the total weight of the prepared honeysuckle is 705 catties, of which the green bar is 450 catties and the white flower is 255 catties.

First of all, the honeysuckle is evenly placed in the trolley tray 16, the height of the honeysuckle is 3cm, and the trolley is pushed into the air duct circulation cavity 3 of the drying room. The trolley is 1 meter away from the axial flow fan frame to avoid The honeysuckle caused by the distance is too close to be blown by the hot wind, the temperature is too high and it blows away, causing damage to the honeysuckle. The trolleys are evenly spaced apart from each other, as well as from the oven walls.

In the first stage, the initial temperature of the drying room is set to 40°C, the humidity is 35%, and the drying is performed for 1 hour. Dry for 2 hours; in the third stage, set the temperature to 46 °C, humidity 25%, and dry for 1.5 hours; set the temperature to 48 °C, humidity 20%, and dry for 1.5 hours in the fourth stage; set the temperature to 50 °C, humidity, and dry for 1.5 hours in the fifth stage 18%, drying for 2 hours; the sixth stage set the temperature to 53°C, humidity 15%, drying for 1.5h; the seventh stage set the temperature to 57°C, humidity 14%, drying for 2 hours; the eighth stage set the temperature to 60°C , humidity 12%, drying for 2.5h; in the ninth stage, set the temperature to 62°C, humidity 10%, drying for 2h. Honeysuckle drying adopts low temperature and slow drying in different periods, low temperature dehumidification, and dehumidification while drying. During the drying process, the axial flow fan is in a working state, sending hot air into the drying room and promoting the air circulation of the drying room. The temperature and humidity sensor is always in the working detection state. When the drying room temperature and humidity do not meet the set requirements, the heat pump will always be in the state of heating and dehumidification; when the set requirements are met, the heat pump will be in the standby working state, so as to achieve the effect of energy saving. During the drying process, you can stop and discharge after observing the color of the honeysuckle through the observation window.

Green strips produce 88 catties of dried flowers, and 5 catties of fresh flowers produce 1 catty of dried flowers. White flowers produce 50 catties of dried flowers, and 5.5 catties of fresh flowers produce 1 catty of dried flowers. After testing and drying, the honeysuckle is turquoise as a whole, with a well-proportioned shape and full color, and has high medicinal and economic value.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the within the scope of protection of the present invention.
