Description

Technical Field

[0001] This utility model belongs to the field of traditional Chinese medicine fermentation technology, specifically relating to a fermentation box for the production of traditional Chinese medicine decoction pieces. Background Technology

[0002] Fermentation of Chinese medicinal herbs is an important technology in the processing and modern manufacturing of Chinese medicine. Through the metabolic action of microorganisms, it can achieve the goals of enhancing efficacy, reducing toxicity, and moderating the medicinal properties. It is widely used in traditional Chinese medicine and modern preparations.

[0003] Existing Chinese medicine fermentation boxes mostly use single-shaft straight paddle stirring or rely on manual turning of materials. There are gaps between the straight paddle and the bottom and edge of the cylindrical fermentation container, which causes the medicinal materials to accumulate in the corners and bottom of the container, resulting in the phenomenon of "local over-fermentation" and "local under-fermentation". For example, root and rhizome medicinal materials are relatively hard, and after accumulation, microorganisms have difficulty penetrating them, resulting in poor fermentation effect and reduced fermentation efficiency. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a fermentation box for the production of Chinese herbal medicine slices, which solves the problem that traditional fermentation equipment often uses a single-shaft straight paddle mixer or relies on manual turning of materials. The gap between the straight paddle and the bottom and edge of the cylindrical fermentation container causes the slices to accumulate in the corners and bottom of the container, resulting in poor fermentation effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fermentation box for the production of traditional Chinese medicine decoction pieces, comprising an outer shell, wherein a plurality of positioning bolts are fixedly arranged around the center line on the top surface of the outer shell, and the positioning bolts are fitted and connected to a mounting cover; a motor is fixedly arranged on the top surface of the mounting cover; the motor is connected to a stirring assembly arranged on the bottom surface of the mounting cover; the stirring assembly is connected to a fermentation cylinder placed inside the outer shell, and the top surface of the fermentation cylinder is movably fitted and connected to the positioning bolts; The stirring assembly includes a rotating rod, the bottom end of which is connected to a helical gear one, and the two sides of the helical gear one are meshed with helical gear two. A protective shell is fitted on the outer side of the helical gear one and the helical gear two, and the two sets of helical gear two shafts pass through and rotatably connect the two sides of the protective shell. The ends of the two sets of helical gear two shafts are respectively connected to stirring rod one and stirring rod two. The bottom ends of stirring rod one and stirring rod two are arc-shaped structures that slide against the inner wall of the fermentation cylinder. The bottom of the fermentation cylinder has several leakage holes.

[0006] The beneficial effects of this utility model are: The mixing component uses helical gear one to drive helical gear two on both sides, so that mixing rod one and mixing rod two form a three-dimensional mixing trajectory. The arc-shaped bottom ends of mixing rod one and mixing rod two fit into the hemispherical inner wall of the fermentation cylinder, which can sweep over all areas of the bottom and edge of the container, without any dead corners in the mixing.

[0007] The insulation layer between the outer shell and the mounting shell can reduce heat loss. Combined with the surrounding silicone heating belt, the temperature inside the fermentation tank can be controlled. The atomizing nozzles of the spiral tube are evenly distributed around the circumference. Combined with the leakage hole at the bottom of the fermentation tank, water accumulation and mold growth or drying of the medicinal slices can be prevented.

[0008] The design of the exhaust port on the rotating ring and the outer shell allows for "exhaust port alignment (aerobic ventilation)" or "exhaust port misalignment (anaerobic sealing)" by rotating the rotating ring. With the connecting cover of the air inlet pipe, the aerobic / anaerobic mode switching can be completed without disassembling the equipment.

[0009] To increase the contact area between the medicinal slices and the tube wall, and reduce dead corners during turning: As a further improvement to the above technical solution: the bottom of the fermentation cylinder is set in a hemispherical shape, and auxiliary lifting plates are fixed on both sides of the top of the fermentation cylinder. Several positioning holes are opened around the center line of the fermentation cylinder on both sides of the top surface of the fermentation cylinder. The center line of the fermentation cylinder is coaxial with the center line of the outer shell. A temperature and humidity sensor is embedded in the inner wall of the fermentation cylinder.

[0010] The beneficial effects of this improvement are as follows: the hemispherical bottom is adapted to the arc-shaped stirring rod, which increases the contact area between the medicinal slices and the cylinder wall and reduces the dead corners of stirring; the auxiliary lifting plate facilitates the loading and unloading of the fermentation cylinder; the positioning insertion hole is fitted with the positioning bolt to ensure that the fermentation cylinder is placed in the center of the outer shell and avoids shaking; the temperature and humidity sensor monitors the environmental parameters inside the fermentation cylinder in real time, providing a basis for adjusting the fermentation conditions.

[0011] To better mix the Chinese herbal medicine slices: As a further improvement to the above technical solution: the helical gear 2 is rotatably installed on the inner walls of both sides of the protective shell, and the stirring rod 1 and stirring rod 2 connected by the shaft of the helical gear 2 are installed in a 90-degree spatially staggered manner, and the bottom ends of the stirring rod 1 and stirring rod 2 both extend to the center position that can contact the inside of the fermentation tank.

[0012] The beneficial effects of this improvement are as follows: the second helical gear rotates within the protective shell via bearings, reducing frictional loss; the first and second stirring rods are spatially staggered at ninety degrees, and their bottom ends extend to the center of the fermentation tank, ensuring coverage of the central and edge areas of the fermentation tank.

[0013] To maintain the temperature inside the outer casing: As a further improvement to the above technical solution: a mounting shell is fitted on the outer side of the bottom end of the outer shell, and an insulation layer is filled between the mounting shell and the outer shell. The insulation layer is made of rock wool or pearl cotton. A silicone heating band is provided inside the insulation layer near the outer wall of the outer shell. The heating band surrounds the circumference of the outer shell. A drain pipe is fixedly installed through the center of the bottom end of the outer shell, and the drain pipe passes through the center of the bottom end of the mounting shell.

[0014] The beneficial effects of this improvement are as follows: the insulation layer between the mounting shell and the outer shell reduces heat loss and maintains a stable fermentation temperature; the silicone heating band surrounds the outer shell and can provide heat to the fermentation tank through heat conduction in low-temperature environments; and the drain pipe collects and drains the water accumulated inside the outer shell.

[0015] To allow for switching between aerobic and anaerobic fermentation as needed: As a further improvement to the above technical solution: a rotating ring is provided on the top surface of the mounting shell and below the top of the outer shell. The rotating ring is rotated and sleeved on the outer side of the top of the outer shell. The top of the outer shell and the outer side of the rotating ring are respectively provided with several exhaust holes one and two around the center line of the outer shell. The inner diameter of the exhaust hole two is the same as that of the exhaust hole one. When the rotating ring rotates, the exhaust hole two can be completely aligned with the exhaust hole one or completely offset. A rubber ring is sleeved on the side of the rotating ring facing the outer shell.

[0016] The beneficial effects of this improvement are as follows: the rotating ring is sleeved on the top of the outer shell. Rotating the rotating ring can align or offset the second exhaust hole with the first exhaust hole. In the ventilated state, it can be used for aerobic fermentation, and in the sealed state, it can be used for anaerobic fermentation. The rubber ring enhances the sealing between the rotating ring and the outer shell, preventing air leakage when misaligned.

Several positioning holes are equidistantly arranged around the bottom end of the mounting cover with the center line of the mounting cover as the center. The center line of the mounting cover is coaxial with the center line of the outer shell. The outer thread of the positioning bolt is connected to a limiting nut.

[0018] The beneficial effects of this improvement are: the spiral tube is arranged circumferentially along the inner top surface of the mounting cover and is coaxial with the fermentation cylinder, and the atomizing nozzle at its bottom end can spray water evenly onto the medicinal slices.

[0020] The beneficial effects of this improvement are: the dynamic sealing ring between the shaft of helical gear one and the protective shell prevents water vapor and food debris from entering the protective shell inside the fermentation tank, thereby preventing damage to helical gear one and helical gear two and reducing their service life.

[0021] To allow for switching between aerobic and anaerobic fermentation as needed: As a further improvement to the above technical solution: an air inlet pipe is fixedly installed through the eccentric part of the top surface of the mounting cover, the outer side of the air inlet pipe is provided with threads, and the top of the air inlet pipe is provided with a connecting cover that is adapted to connect with the outer threads.

[0022] The beneficial effects of this improvement are: the connecting cap is connected to the air inlet pipe by threads, which seals the air inlet channel during anaerobic fermentation and prevents air from entering.

[0023] In order to achieve unified control of this device: As a further improvement to the above technical solution: a controller is provided on one side of the mounting shell, and the controller is equipped with a PLC microcontroller, a relay module, and a control switch.
