Why is there dried onion?

As mentioned, onion is a vegetable that contains a lot of vitamins and is popularly used for its medicinal properties. Did you know citizens in African countries eat 30kg of goods per person per year. Although the quantity consumed in Russia is not much, most of the vegetable gardens are grown.

Despite such a large amount of consumption, this fresh tuber is difficult to preserve. Therefore, the drying method was born to ensure that the shirt is kept for a long time without losing the nutritional content inside.

What are the ways to make dried onions?

Drying is not a strange method to preserve agricultural products, so there are many ways to make dried onions. To get the freshest product, you should choose high-quality, undamaged onions. The following are the drying methods commonly used by us.

Microwave drying

After the onion is peeled and cut into slices displayed on a baking tray, then use a temperature of 50 to 60 degrees Celsius. Depending on the size of each slice and the quantity of the product, the drying time is from 3 to 6 hours.

Use an electric dryer

In addition to the above common method, from modern household appliances today there is a type of electric dryer that is used to make dried onions. After cleaning the ingredients and preliminary grinding to be evenly distributed on the baking sheet, it will be dried at a temperature of 55 to 65 degrees Celsius for 6 to 7 hours.

Dry naturally

Sun drying is the most traditional method dating back many generations. After preliminary processing of onions, we will dry them in the open air for 5 to 7 days to obtain dried onions. However, this method does not guarantee food safety because outside the air there is a lot of dirt and bacteria that we cannot see.

Use a cold dryer

This is the most modern method today using a freeze dryer. The method is very simple, after you have cleaned the onions and prepared them, put them in the drying trays. Arrange the onion slices with gaps to ensure that the onions are evenly dried. Will use a temperature of 55 to 70 degrees Celsius for 5 to 6 hours depending on the thickness of the onion slices.

This method has an advantage over other methods because it should preserve the color of the onion as well as the nutritional content inside. If the taste and color are preserved, this mechanical product is really optimal.

The working principle of SUNSAY refrigeration dryer is as follows:

The refrigeration system is a closed operation cycle, the air is convection and recirculation thanks to the convection fan system, without exhausting the drying air.

The drying air from the drying chamber returns to the dehumidification cooling system. Here, the air is cooled to the dew point, the moisture in the air is separated out in the form of water. Water is collected and discharged through a separate water pipeline.

– After being dehumidified and dried, the air is re-heated to the set temperature to be dried and returned to the drying chamber.

– In the drying chamber, with the difference in humidity, the moisture on the product is absorbed by the dry air and dries the product.

– The air convection system of the SUNSAY refrigeration dryer is designed on a separate principle to ensure that the air is evenly distributed in all trays and on the product surface to help the product dry evenly and uniformly.

– Refrigeration dryer operates in a closed cycle, so the temperature and humidity outside the environment do not affect the work, and the drying time of fruits, agricultural products, and vegetables.

Refrigeration system is optimally designed to ensure the highest drying efficiency.
