Description

Technical Field

[0001] This utility model relates to the field of food drying technology, and in particular to a drying device. Background Technology

[0002] When processing ginseng, medicinal herbs, and dried mountain products, people usually need to sun-dry or oven-dry the freshly harvested mountain products. Oven-drying removes moisture from ginseng and mountain products, prevents mold growth, and facilitates preservation and sale. The sun-drying process is greatly affected by the weather. When there is cloudy or rainy weather with insufficient sunshine, traditional sun-drying takes a long time, making it difficult to achieve large-scale production and wasting a lot of manpower and resources. The drying efficiency is relatively low. On the other hand, there is a lack of drying equipment specifically for mountain products. Using ordinary drying equipment often results in uneven drying of mountain products, making them prone to yellowing and scorching, resulting in low quality and poor appearance, which is difficult to meet current needs.

[0003] Existing hot air heating dryers have internal heaters for drying, but these dryers are complex in structure, large in size, have low heating efficiency, large heat loss, high power consumption, and the hot air has only one temperature, making it impossible to achieve temperature changes. They are also inconvenient to move. In contrast, dryers that use chain plates to dry materials achieve temperature changes as they pass through each chain plate. However, these dryers are difficult to manufacture, heavy, and difficult to move due to the numerous heating tubes between the chain plates. They also cannot achieve automatic temperature and humidity control, resulting in higher operating costs. They are not suitable for drying ginseng, mountain products, etc.

[0004] Therefore, it is of great significance for engineers and technicians in this field to develop a dryer that is low in manufacturing cost, easy to use, energy-saving and environmentally friendly, small in size, short in drying time, requires less manpower, can perform batch drying, has good drying effect, and is easy to operate, so as to meet the current processing needs.

[0048] The working principle of this utility model:

[0049] When the start button is pressed on the control box of this utility model, the electric heating furnace 11 for wood and straw starts, and the variable frequency motor 17 starts. The rotation of the conveyor chain drives the feeding shaft 14 to rotate, thus conveying the wood and straw in the hopper 16 into the heating furnace body 18. It is then ignited by the electric igniter 20. The heat is then transported to the heat exchanger 7 of the machine body 1 (dryer) through the heating pipe 9, where the heating fan 12 provides airflow to aid combustion. Once the heat enters the heat exchanger 7, the variable frequency shaft fan 23 above the heat exchanger 7 starts operating when the control box detects a low temperature through the installed temperature and humidity sensors. Under the action of the variable frequency shaft fan 23, the heat in the heat exchanger 7 enters the tray 4 through the ventilation holes (each set of tray supports is equipped with 39 ventilation holes, each 10mm in diameter). Hot air flows into each row of supports through the ventilation holes. Ginseng, mountain products, and other products awaiting drying are placed on the tray 4, awaiting drying.
