Description

A drum-type high-efficiency mulberry leaf drying device

technical field

The invention relates to a drying device, in particular to a drum-type high-efficiency mulberry leaf drying device.

Background technique

Mulberry Leaf, scientific name: Folium Mori. The name of traditional Chinese medicine is the dry leaves of the Moraceae plant mulberry, which is the daily food of silkworms. The main food of silkworms. The complete leaves are or broadly ovate, about 15 cm long and 10 cm wide, with petioles about 4 cm long, heart-shaped at the base of the blade, slightly pointed at the top, serrated at the edge, densely white pubescent in the veins. Older leaves are thicker and dark green. Young leaves are thin, yellow-green. Crisp and easy to hold. Gas light, slightly bitter taste.

For medicinal purposes, it is generally believed that the quality of the harvest after frost is good. Mulberry leaves have the effects of dispelling wind-heat, clearing lung and moistening dryness, clearing liver and improving eyesight. And it has the effect of treating wind-heat cold, lung heat and dry cough, dizziness and headache, red eyes and dim eyesight. By 2014, someone made the buds of mulberry leaves into dishes, which made the mulberry leaves have therapeutic value. Because of the rich nutritional value of the buds of mulberry leaves, they were loved by the public, and they were called mulberry sprouts. In Nanxun Jili Village, the mulberry buds of Guosi Cultural Park are the most outstanding. Considering the irrigation of Zhuanzhu Bay water, the trace elements of the mulberry buds are much higher than those of ordinary mulberry buds.

The mulberry leaves just picked from the mulberry tree contain a certain amount of water. In order to facilitate storage and transportation, the mulberry leaves need to be dried. Most of the existing mulberry leaf drying devices are tunnel-type, that is, put the mulberry leaves on the conveyor belt, and then use the heat source to dry the mulberry leaves. Due to the long transmission distance and large space, the nutrients of the mulberry leaves cannot be well locked. It causes nutrient loss, thereby affecting the nutritional value of mulberry leaves; at the same time, the mulberry leaves cannot be turned well on the conveyor belt, which easily leads to uneven heating, which makes the drying effect of mulberry leaves not ideal.
