    How does the temperature rise slowly in the early stage of heat pump drying? The solution is here

    Author: Lucy, source: Zhengxu air energy, published on March 20, 2020, click: 2161

              The heat pump dryer with polyurethane drying room is the best choice for drying herbs, fruits and vegetables and seafood. But many engineers or customers found that the temperature rise slowly in the early stage of drying. So, is it normal that the temperature rises slowly in the early stage? Is there any way to raise the pre temperature? Zhengxu has rich experience in heat pump drying. Now, the technical director of Zhengxu will answer the problem of slow temperature rise in the early stage.


     How to do if the temperature rises slowly in the early stage of heat pump drying


               The temperature rises slowly ≠ the temperature doesn't go up

              First of all, we have a clear concept that the slow rise of temperature in the early stage does not mean that the temperature can not go up. The drying temperature can't go up The construction defects of drying room lead to heat loss, or the wrong heat pump model may be selected. The southern drying heat pump is used in the severe cold north, which leads to the heat pump's acclimatization and temperature. These all need professional drying technical personnel one by one to eliminate the problem, in order to solve.

              It is a normal phenomenon that the temperature rises slowly in the early stage of drying. Because the heat transferred from the air by the drying heat pump needs to raise the internal room temperature of the drying room from the normal temperature to more than 50 ℃, commonly known as "preheating the drying room". terms of settlement : in order to improve the preheating temperature quickly in the early stage of drying, the electric heating auxiliary heating can be added to meet the problem that the pre heating temperature is difficult to go up. The maximum power can also be set before drying to increase the temperature, which needs to be adjusted with the manufacturer's electric control design.

              At present, Heat pump dryer Depending on the intelligent control panel, it can provide precise temperature control of drying room to meet the requirements of moisture removal and temperature rise and fall of different materials. As Zhengxu's more than ten years drying experience, especially in tobacco, seafood, rose and other materials experience and technology, to provide professional solutions to slow temperature rise in the early stage, drying room dehumidification in the middle drying process, for the drying process of Salvia miltiorrhiza blackening, honeysuckle blackening and other issues have a unique solution.
