Heat pump dryer

Introduction of agaric dryer:
        The agaric is a kind of artificial cultivated edible vegetable, and its edible part is the colloid fruiting body. The agaric after drying can be storaged for long time.
        The agaric dryer is composed of: 1. Heating device and moisture reducing device. 2. Heat preservation chamber. 3. Hot air circulation system. 4. Intelligent controlling system. The heating device is for generatoring the hot air, and circulation system is to ensure the temperature and inside airflow uniform. While, the intelligent controlly system is to make the whole drying process with constant temperature and constant humidity to ensure the drying quality.

The agaric drying process:
        1. Collecting requirements.
        When the agaric unfold, the fruiting body venter has the white conidial powder, and this time is the best collecting time. The collecting time should be in the morning of sunny day or the sunny day after rain, and at this time the agaric will be at the soft condition. Pick the agaric without ear, and should not hurt the ear buds. The fresh agaric has high water content, so the picked agaric should be put on the mat in the open air for cooling.
        2. The storage characteristics.
        The agaric storage optimum temperature should be 0, and relative humidity should be 95%. Becuase the agaric is the colloid edible fungus, texture soft, and prone to stick to block, they should be timely ventilated in case of mildew. So we’d better choose to dry the agaric for long time storaging.
        3. The agaric drying.
        The agaric drying temperature should start from 35℃, if the temperature is over high, it will be unable to keep up with the dehumidifying system, which will easily cause deformation. After drying the agaric under 35-40℃ for 4 hours, we can increase the temperature of the agaric drying machine to 45-50℃ and dry for 5 hours. The highest drying temperature should not exceed 60℃, and dry the agaric at 45-50℃ condition till to be dry. The whold drying process will need 10-14 hours. Because of the agaric drying temperature, size of drying chamber, different ventilation mode condition, the specific drying process should be flexible application in accordance with the specific condition.

The features of agaric drying equipment.
        1. Automatic PLC controlling system.
        2. High controlling precision of temperature and humidity.
        3. Low energy consumption, and low operation cost.
        4. Safe, no overheating or burning dangerous when drying process.
        5. Draining moisture evenly.
        6. Widely application and not affected by weather.
        7. Long lifetime heat pump dryer and low maintenance cost.
        8. Environmental protection.
