Description

Technical Field

[0001] This utility model relates to the field of Angelica sinensis processing technology, specifically a device for freeze-drying Angelica sinensis. Background Technology

[0002] Angelica sinensis is a traditional Chinese medicine. It is the dried root of the Angelica sinensis plant, belonging to the Apiaceae family. It has the basic functions of nourishing blood and promoting blood circulation, regulating menstruation and relieving pain, and moistening the intestines and promoting bowel movements. Freeze-dried Angelica sinensis involves freeze-drying the root, which requires pre-freezing at low temperatures before freeze-drying.

[0003] In the existing low-temperature pre-freezing process, Angelica sinensis needs to be placed on a tray inside a pre-freezing machine, and then the pre-freezing machine pre-freezes the Angelica sinensis at low temperature. After the low-temperature pre-freezing is completed, the Angelica sinensis on the tray inside the pre-freezing machine is taken out, and then new Angelica sinensis is placed on the tray inside the pre-freezing machine. The time spent in the process of loading and unloading Angelica sinensis seriously affects the efficiency of the pre-freezing work. Utility Model Content

[0004] The purpose of this invention is to provide a device for freeze-drying Angelica sinensis, so as to solve the problem mentioned in the background art that the time-consuming process of loading and unloading Angelica sinensis seriously affects the efficiency of pre-freezing.

The guide rail is horizontally arranged on top of the connecting plate and the two bearing plates. The movable frame is slidably installed on the guide rail. The two placement components are symmetrically arranged on the top sides of the movable frame. The screw slide is horizontally arranged on top of the connecting plate and the two bearing plates. The linkage plate is installed on the movable end of the screw slide and is connected to the bottom outer wall of the movable frame.

[0007] Furthermore, the placement assembly includes a horizontal plate, a placement rack, and multiple placement components. The horizontal plate is horizontally arranged on top of the movable frame, the placement rack is installed on top of the horizontal plate, and the multiple placement components are spaced apart within the placement rack. Each placement component includes a tray and two limiting plates. The two limiting plates are symmetrically arranged within the placement rack, and the tray is slidably mounted on the two limiting plates.

[0008] Furthermore, the lifting assembly includes a first lifting seat, a second lifting seat, a pulley, a drive shaft, a drive roller, a steel rope, and a drive motor. The first and second lifting seats are spaced apart and disposed at the top of the inner part of the mounting frame. The pulley is rotatably mounted inside the first lifting seat, the drive shaft is rotatably mounted inside the second lifting seat, the drive roller is mounted on the drive shaft, the top end of the steel rope is connected to the drive roller, and the bottom end of the steel rope passes through the pulley and is connected to the top of the connecting plate.

[0010] Furthermore, a control panel is provided on the front outer wall of the pre-freezing machine.

[0011] Furthermore, the pre-freezing machine is provided with four rectangularly distributed support legs at its bottom.

[0012] This utility model provides an improved device for freeze-drying Angelica sinensis, which has the following improvements and advantages compared with the prior art:

[0013] Firstly, this invention involves placing the angelica root to be freeze-dried into one of the placement components. Then, a screw slide, using a linkage plate, moves a movable frame horizontally to the left on the guide rail. The movable frame moves this placement component to the left into the pre-freezing machine. At this time, the other placement component is located outside the pre-freezing machine. Then, a lifting component moves a connecting plate downwards, which in turn moves two baffles downwards, blocking most of the inlet and outlet slots. The pre-freezing machine then performs low-temperature pre-freezing on the angelica root. Simultaneously, another portion of the angelica root to be freeze-dried is placed into the other placement component. After the angelica root in the pre-freezing machine is pre-frozen, the lifting component moves the connecting plate and the two baffles upwards to reset. Then, the screw slide continues to move the movable frame horizontally to the left on the guide rail. This placement component is removed from the pre-freezing machine, and the other placement component enters the pre-freezing machine, thus completing the replacement operation. The efficiency of the pre-freezing process is not affected by the loading and unloading process of the angelica root.

[0014] Secondly, this utility model uses a drive motor to drive the drive shaft and drive roller to rotate. The drive roller causes the top of the steel rope to be wound around its surface. Then, the steel rope uses pulleys to pull the connecting plate upward. When the connecting plate needs to move downward, the drive motor rotates in the opposite direction.
