Onion drying process<\/h2>

In the onion drying process, it is necessary to pay attention to temperature, humidity and drying time.<\/p>

  1. Temperature: The drying temperature of onion should not exceed 50 \u2103, and the dehumidification rate should reach more than 20% when drying. Drying can be carried out in several stages. The initial drying temperature is set at 50-40 \u2103, the second stage is set at 40-30 \u2103, and the third stage will be reduced to about 35 \u2103.<\/li>
  2. Humidity: For vegetables with high moisture content, the moisture discharge must be controlled. Because this is also one of the important factors that determine the drying quality.<\/li>
  3. Drying time: The drying cycle of onions is generally about 15 hours. Rapid drying will damage the drying quality.<\/li> <\/ol>

With the development of food technology, most food processing plants use onion dryer<\/a>s to dry onions. In the onion drying process, the onion dryer machine generally adopts the method of low temperature hot air and constant temperature drying. Because high temperature will destroy the nutritional value of vegetables and make them lose nutrients.<\/p>
