Description

Technical Field

[0001] The utility model relates to the technical field of root tea processing equipment, in particular to a root tea deep processing drying machine. Background Art

[0002] With the development of society and the improvement of living standards, people gradually have a certain demand for dandelion root tea with health and health functions. Dandelion root is cold in nature. Eating it in moderation can remove heat toxins and clear liver heat in the human body. It has obvious therapeutic effects on redness, swelling, pain, wound infection and suppuration caused by dry heat in the human body. In addition, dandelion root tea contains a large amount of protein, various trace elements and carbohydrates. Drinking it in moderation nourishes the skin and promotes skin cell regeneration and metabolism. Dandelion root tea mainly includes cleaning, cutting, drying and other processes during processing. In the drying process, a dryer is generally used to dehydrate the root tea. The working mode of the existing dryer is mainly to place the dandelion root on a special tray, and then place the tray in a drying box. The moisture of the dandelion root tea raw material is volatilized by heating the drying box, thereby playing a drying role. However, this drying method is due to the limited contact surface between the surface of the tray and the dandelion root tea raw material, resulting in very low drying efficiency, and it is also necessary to turn the dandelion root tea raw material regularly, so a root tea deep processing dryer is developed.

[0019] like Figure 1-Figure 4 As shown, a root tea deep processing drying machine includes a base 1, a drying drum 2 rotatably mounted on the base 1, a driving mechanism for driving the drying drum to rotate, and two electric heating furnaces 3 symmetrically mounted on the base 1 for heating the drying drum 2.

[0020] The drying cylinder 2 includes an outer cylinder 2-1, and the base 1 is provided with a rectangular through groove 4 at the bottom of the outer cylinder 2-1, and a plurality of groups of supporting wheels 5 symmetrical along the through groove are evenly and rotatably installed, and each supporting wheel 5 is in rotational contact with the outer periphery of the outer cylinder 2-1.

[0021] One end of the outer cylinder 2-1 is an open structure and the other end is a closed structure. An inner cylinder 2-2 that matches its axis is fixedly installed inside the outer cylinder 2-1. One end of the inner cylinder 2-2 is fixedly connected to the closed end of the outer cylinder 2-1, and a plurality of long strip-shaped discharge holes 2-3 are evenly opened along the circumferential direction at the part of the inner cylinder 2-2 close to the closed end of the outer cylinder 2-1. The other end of the inner cylinder 2-2 extends to the outside of the open end of the outer cylinder 2-1. A first spiral blade 2-4 is fixedly arranged on the inner circumferential wall of the outer cylinder 2-1, and a second spiral blade 2-5 with a rotation direction opposite to that of the first spiral blade 2-4 is fixedly arranged on the inner circumferential wall of the inner cylinder 2-2.

[0022] In this embodiment, the driving mechanism includes a driving motor 6 fixedly installed in the middle of the bottom of the base 1, a transmission gear 7 is installed at the free end of the driving shaft of the driving motor 6, and a transmission gear ring 8 meshing with the transmission gear 7 is fixedly sleeved in the middle of the outer peripheral wall of the outer cylinder 2-1.

[0023] As a further improvement of the present invention, a plurality of support sleeves 9 are evenly spaced and fixed on the outer peripheral wall of the outer cylinder 2-1. Two vertical mounting plates 10 are symmetrically fixed on the base 1 on both sides of each support sleeve 9, and each support wheel 5 is rotatably mounted on the mounting plate 10 and in rotational contact with the outer peripheral wall of the support sleeve 9.

[0024] In addition, a limiting convex ring 11 is disposed on the outer circumference of each supporting sleeve 9 , and a limiting groove 12 matching the limiting convex ring 11 is formed along the circumferential direction of each supporting wheel 5 .

[0025] When the utility model is working, the drying cylinder is firstly preheated and heated by an electric heating furnace, and after the outer cylinder and the inner cylinder have a certain temperature, the dandelion root tea material to be dried is put from one end of the inner cylinder located outside the outer cylinder, and the driving motor is started to rotate the drying cylinder. Since the inner cylinder and the outer cylinder are both provided with spiral blades, the material is turned over and spirally conveyed during the rotation of the inner cylinder and the outer cylinder, and the second spiral blade on the inner cylinder and the first spiral blade on the outer cylinder have opposite rotation directions, so that the material can be gradually conveyed from the inner cylinder to the closed end of the outer cylinder, and then enter the outer cylinder through the multiple discharge holes and be gradually conveyed to the open end of the outer cylinder, thereby realizing automatic discharge and ensuring that the material has a longer formation inside the drying cylinder, further ensuring the drying efficiency.
