Drying lemon slices

Lemon is also known as motherwort which is rich in nutrients, including vitamin B1, B2, vitamin C, calcium, phosphorus, iron, nicotinic acid, quinic acid, citric acid, malic acid, hesperidin, naringin, coumarin, high potassium and low sodium. It can improve blood circulation, prevent thrombosis, effectively reduce skin pigmentation, prevent colds, stimulate hematopoiesis, and prevent some cancers. However, it is very sour when eaten raw, so it is usually processed into lemon juice, jam, dried lemon slices, etc.

1. Select high-quality lemons and wash them. The purpose of this step is to remove pesticide residues or wax on the surface. Salt water, soda water or ultrasonic cleaning can be used for washing.

2. Slice. Use manual or slicer to cut the lemon into slices of about 4mm, ensuring uniform thickness, and remove seeds to avoid affecting the drying effect and the final taste.

3. According to your own requirements, you can soak the lemon slices in syrup for a period of time. Because the water with low density will flow to the water with high density, the water of the lemon slices will flow to the syrup and lose some water, which saves drying time.

4. Preliminary dehydration. Place the cut lemon slices on a ventilated tray to avoid stacking, and use natural wind and light to remove some water from the lemon slices.

5. Drying. Push preliminarily dehydrated lemon slices to drying room, set the temperature, and divide it into three sections for a total of 6 hours:

Temperature 65℃, hysteresis 3℃, humidity 5%RH, time 3 hours;

Temperature 55℃, hysteresis 3℃, humidity 5%RH, time 2 hours;

Temperature 50℃, hysteresis 5℃, humidity 15%RH, time 1 hour.

When drying lemon slices in batches, pay attention to the quality of the finished product, the environmental protection and efficiency of the process, and the safety of machine operation. The drying process is about the precise control of temperature, humidity, air volume and wind speed. If you want to dry other fruit slices such as apple slices, mango slices, banana slices, dragon fruit slices, hawthorn slices, etc., the key points are also same.
