Description

Technical Field

[0002] Primary processing of fruits and vegetables refers to a series of treatments on fresh fruits and vegetables, the purpose of which is to improve their freshness, increase added value, and prepare them for subsequent processing or direct consumption. The drying step in the primary processing of fruits and vegetables is an important step. It extends the shelf life of fruits and vegetables by removing moisture, and the appropriate drying method can retain the original flavor and nutritional value. Hot air drying equipment is used during drying. Hot air drying equipment is mainly used to remove moisture from fruits and vegetables to extend their shelf life.

[0003] Most of the existing hot air drying equipment is a box. When fruits and vegetables need to be dried, the box is opened and the fruits and vegetables are added, and then the hot air device is started to dry the fruits and vegetables inside the box. During drying, the fruits and vegetables remain in the same posture, resulting in the hot air being unable to fully contact the fruits and vegetables, affecting the drying effect of the fruits and vegetables. Moreover, after drying is completed, the box needs to be opened to take out the fruits and vegetables, causing a large amount of hot air to escape, and hot air needs to be added again, which increases energy consumption.
