A drum type mulberry leaf drying device

Abstract

The invention discloses a roller type efficient mulberry leaf drying device. The roller type efficient mulberry leaf drying device comprises a base, a roller, a transmission mechanism and an air heater; two stand plates are arranged on the left and right sides of the top of the base; a cross beam is connected to the tops of the stand plates on the two sides; the roller is arranged above the base;a left rotating shaft and a right rotating shaft are respectively connected to the centers of the end surfaces on the two sides of the roller; the right rotating shaft is an extension shaft with a hollow design; a transmission shaft for driving the left rotating shaft to rotate is arranged on the left side of the left rotating shaft; the transmission shaft is provided with a transmission mechanismfor driving the transmission shaft to rotate; the air heater is mounted on the right side of the base; a hot air pipe upwards extends to penetrate through the stand plate on the right side, and extends into the roller in the axis direction of the right rotating shaft; exhaust ports are densely formed in the hot air pipe; and an overturning rod is arranged at the outer periphery of a pipe body ofthe hot air pipe. The mulberry leaf drying device can effectively prevent nutrient loss of mulberry leaves to guarantee no influence on nutritional value of the mulberry leaves, and meanwhile, is uniform in heating of the mulberry leaves and excellent in drying effect to guarantee the quality grade of dried finished products.

Description

technical field [0001] The invention relates to a drying device, in particular to a drum-type mulberry leaf drying device. Background technique [0002] Mulberry Leaf, (Mulberry Leaf), scientific name: Folium Mori. The name of Chinese medicine is the dry leaves of the mulberry plant, the daily food of silkworms. The main food of silkworms. The complete leaf blade is or broadly ovate, about 15 cm long, about 10 cm wide, petiole about 4 cm long, the base of the leaf blade is heart-shaped, the top is slightly pointed, the margin is serrated, and the veins are densely white and pubescent. Older leaves are thicker and darker green. Young leaves are thin, yellow-green. Crispy and easy to hold. Light gas, slightly bitter taste. [0003] Medicinal products are generally considered to be of good quality when harvested after the cream. Mulberry leaves have the effect of dispersing wind-heat, clearing the lungs and moistening dryness, clearing the liver and improving eyesight. ...

AI Technical Summary

Problems solved by technology

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. Cause nutrient loss, thus affecting the nutritional value of mulberry leaves; at the same time, the mulberry leaves cannot be turned well on the conveyor belt, which will easily lead to uneven heating, making the drying effect of mulberry leaves not ideal
