The heat pump dryer is a device that can use the heat in the air to dry, and can be applied to the drying of various fruits, vegetables, seafood, meat and other foods. The temperature setting of the heat pump dryer for drying lemons needs to take into account the characteristics of lemons and the purpose of drying. Generally speaking, the drying temperature of lemons should be between 50-60 degrees Celsius, which can ensure that lemons will not deteriorate or lose their nutrients due to excessive temperature.

First, cut the lemons into appropriately sized chunks and distribute them evenly on the dryer sheet to ensure they are evenly heated.
Secondly, for fruits with high water content such as lemons, it is recommended to choose a lower drying temperature to avoid over-drying and resulting in quality degradation. Generally speaking, it is recommended to set the drying temperature between 50°C-60°C.
Finally, since lemons contain citric acid, they may develop some sourness during the drying process. To avoid this, you can sprinkle some sugar on the lemons to neutralize the sourness.

It should be noted that in the process of drying lemons in a heat pump dryer, a lower drying temperature and a longer drying time should be selected to fully retain the flavor and nutrients of lemons. Generally speaking, the temperature setting range of the heat pump dryer is wide, and the appropriate temperature and time can be selected according to the characteristics of the lemon and the purpose of drying.
