Drying seedless grapes | TROCKNNER fruit dehydrator
How to dry grapes?
Generally speaking, the temperature for drying grapes should be between 40°C and 60°C, and the drying time should be determined according to the thickness and humidity of the grapes. If the temperature is too high, the surface of the grapes will be dehydrated too quickly, and the internal water cannot be completely evaporated, resulting in the outer layer of the raisins becoming hard and the interior being damp; while the temperature is too low, the drying time will be too long, which will easily cause problems such as mildew on the surface of the grapes. Therefore, the best way is to experiment, observe the effect of drying grapes, and adjust the temperature and time to achieve the best results before starting to dry.
Steps
1. Prepare the grapes: Choose ripe grapes that are not rotten. You can wash the grapes with water and shake them dry.
2. Prepare the dryer: Set the TROCKNNER dryer to the appropriate temperature and humidity. Generally speaking, the temperature should be between 40 and 60 °C and the humidity should be between 30 and 50%.
3. Place the grapes: Place the prepared grapes evenly on the drying tray of the dryer.
4. Turn on the dryer: Turn on the dryer and set the drying time according to the dryer's instructions. Generally speaking, the drying time of grapes should be determined according to the type, size and moisture content of the grapes. The drying time usually takes between a few hours and a day.
5. Check the grapes: During the drying process, you can periodically check the condition of the grapes to make sure they are not too dry. If the grapes have dried out, you can remove them.
Attention
In general, the temperature of the TROCKNNER dryer should be kept between 40 and 60 °C, with a relative humidity of between 30 and 50 %. Different grape varieties and their humidity levels may require adjustments in drying time and temperature. Therefore, it is important to know the specific characteristics of the grapes you are going to use and set the parameters of the heat pump dryer according to your needs.
