Onion is a multifunctional health food, which has many functions such as lowering blood pressure, refreshing, increasing metabolism, anti-aging, and preventing osteoporosis. The dried onions can be made into onion powder, which is widely used in nutrition and health products, functional foods, seasonings, convenience foods, etc. Traditional drying methods such as drying in the sun tend to cause excessive heat and necrosis of the onion skin, and the temperature is not controlled, and it is prone to mosquitoes and rain. Our drying oven can dry onions efficiently and quickly while ensuring quality.
Why choose our onion drying machine؟
Hot air circulation drying oven has reached the advanced level at home and abroad by a lot of upgrading, SL-C series special drying oven adopts the axial flow fan, with the automatic constant temperature control system. Its thermal efficiency is more than 95%, adopts a convective heat transfer method to heating the air. Fresh air from the air inlet supplement, waste damp is out from the dehumidification system. Constantly added fresh air and discharged damp to keep the correct relative humidity in the oven. The biggest characteristic of this series of drying ovens is part of the hot air cycling in the cabinet, the entire cycle is closed, so as to enhance the heat transfer, saving energy.
The process of the onion drying
The drying process should be based on different varieties to determine different drying temperatures and drying time, the color and moisture content of the finished product. Next, I will introduce the process of drying onions.

- Drying time: The drying cycle for a batch of onions is about 15 hours, and rapid drying will destroy the quality of the product.
- Humidity: The moisture of onions contains a certain amount of sugar, which makes dehydration difficult. Controlling the speed of dehydration is critical.
The advantages of the onion drying machine
- පන්දු ඇතුළත් පිටත් අයුතු වන්නේ ස්ථාවර පිටතින් පිලිපහසු බවක් හා තද බව නොමැති බවත්, දිරිමත්ව ඇති තරම සහ නොදෙම්රියා වියළීමේ විලාපය තුළ සිටීමයි.
