Description

Technical Field

[0001] This utility model relates to the technical field of raw material processing equipment for *Aspergillus cristatus* tea, and in particular to a raw material mixing device for the production of *Aspergillus cristatus* tea. Background Technology

[0002] Eurotium cristatum, also known as "golden flower," can secrete amylase and oxidase, which can catalyze the conversion of proteins and starches in tea into monosaccharides and catalyze the oxidation of polyphenolic compounds, transforming them into substances beneficial to the human body, thereby improving and optimizing the taste and other characteristics of tea.

[0003] In the process of making *Aspergillus cristatus* tea, *Aspergillus cristatus* fermentation agent needs to be mixed with water to make a fermentation liquid. Currently, the fermentation agent is mixed by pouring powdered fermentation material and water into a mixing device, and then using a drive motor to drive the stirring rod to stir the fermentation agent. However, during the mixing process, the raw materials are prone to clumping and settling at the bottom of the device, resulting in low uniformity of mixing and thus reducing the quality of the fermentation agent. Utility Model Content

[0004] This utility model discloses a raw material mixing device for the production of *Aspergillus cristatus* tea, which mainly solves the problem that the raw materials are prone to clumping and settling to the bottom of the device during the mixing process.

[0005] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows:

[0006] This utility model provides a raw material mixing device for the production of *Aspergillus cristatus* tea, including an outer cylinder and an inner cylinder disposed inside the outer cylinder. The inner cylinder is provided with a mixing chamber, and the mixing chamber is provided with a stirring mechanism driven by a motor. The bottom of the inner cylinder is provided with a drain pipe.

[0007] The stirring mechanism includes a stirring shaft driven by a motor, the end of which extends into a drain pipe. The stirring shaft is equipped with stirring blades, a first spiral blade positioned corresponding to the drain pipe, and a second spiral blade positioned corresponding to the stirring blades. Along the direction from the drain pipe to the motor, the spiral directions of the first and second spiral blades are opposite to the rotation direction of the stirring shaft. A feed hopper is located at the end of the stirring shaft near the motor, and a feed channel is provided within the stirring shaft. A feed hole communicating with the feed channel is located on the stirring shaft corresponding to the feed hopper. Discharge holes communicating with the feed channel are located along the lower part of the second spiral blade on the stirring shaft.

[0008] In one embodiment, a cleaning component is provided on the stirring shaft. The cleaning component includes a cleaning frame, which is equipped with a detachable rubber scraper that abuts against the bottom of the mixing chamber.

[0009] In one embodiment, the cleaning rack is provided with an installation groove, the bottom of the installation groove is provided with a limiting groove, the rubber scraper is embedded in the installation groove, and a limiting strip is provided at the position of the rubber scraper corresponding to the limiting groove, the limiting strip being embedded in the limiting groove.

[0010] In one embodiment, a gap is formed between the outer cylinder and the inner cylinder to form a heat-insulating cavity, and the outer cylinder is provided with an inlet pipe and an outlet pipe communicating with the heat-insulating cavity.

[0011] In one embodiment, a plurality of heating tubes are provided at the bottom of the heat-insulating cavity.

[0012] In one embodiment, a spiral guide plate is provided along the outer wall of the inner cylinder in the insulation cavity, and a spiral guide channel is formed between the surface of the spiral guide plate, the inner wall of the outer cylinder, and the outer wall of the inner cylinder.

[0013] The advantages or beneficial effects of the above technical solution include at least the following: when the motor drives the stirring shaft to rotate, the stirring blades, the first spiral blade, and the second spiral blade of the stirring mechanism can mix and stir the fermenting agent and water. During the stirring process, the first and second spiral blades can push the fermenting agent and water at the bottom of the mixing chamber upwards. After being stirred by the stirring blades, the uniformity of the stirring can be improved. At the same time, with the cooperation of the feeding hopper, feeding channel, feeding hole, and discharging hole, after the fermenting agent is put into the feeding hopper, the fermenting agent will enter the feeding channel through the feeding hole along with the feeding hopper. The centrifugal force generated by the rotation of the stirring shaft will throw the fermenting agent in the feeding channel out of the discharging hole, thereby further improving the uniformity of the mixing. When the fermentation liquid is discharged through the drain pipe, after passing through the first spiral blade, the discharged fermentation liquid can form a spiral, thereby improving the discharge efficiency.

[0033] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0034] See Figure 1 , Figure 2 , Figure 3 and Figure 5 The present invention provides a raw material mixing device for producing *Aspergillus cristatus* tea, including an outer cylinder 1 and an inner cylinder 2 disposed inside the outer cylinder 1. The inner cylinder 2 is provided with a mixing chamber 21, and a stirring mechanism 3 is provided in the mixing chamber 21. The stirring mechanism 3 is driven by a motor 4. A drain pipe 5 is provided at the bottom of the inner cylinder 2. A valve can be provided on the drain pipe 5 to control the opening and closing of the drain pipe 5.

[0035] The stirring mechanism 3 includes a stirring shaft 31 driven by a motor 4. The end of the stirring shaft 31 extends into the drain pipe 5. A stirring blade 32 is provided on the stirring shaft 31. A first spiral blade 33 is provided on the stirring shaft 31 at the position corresponding to the drain pipe 5. A second spiral blade 34 is provided on the stirring shaft 31 at the position corresponding to the stirring blade 32. Along the direction from the drain pipe 5 to the motor 4, the spiral direction of the first spiral blade 33 and the second spiral blade 34 is opposite to the rotation direction of the stirring shaft 31. A feed hopper 35 is provided at the end of the stirring shaft 31 near the motor 4. A feed channel 311 is provided in the stirring shaft 31. A feed hole 312 communicating with the feed channel 311 is provided on the stirring shaft 31 at the position corresponding to the feed hopper 35. A discharge hole 313 communicating with the feed channel 311 is provided on the stirring shaft 31 below the second spiral blade 34.

[0036] With the above structure, when the motor 4 drives the stirring shaft 31 to rotate, the stirring mechanism 3, with its stirring blades 32, first spiral blades 33, and second spiral blades 34, can mix and stir the fermenting agent and water. During the stirring process, the first spiral blades 33 and second spiral blades 34 can push the fermenting agent and water at the bottom of the mixing chamber 21 upwards. After being stirred by the stirring blades 32, the uniformity of the stirring can be improved. At the same time, with the cooperation of the feed hopper 35, feed channel 311, feed hole 312, and discharge hole 313, after the fermenting agent is put into the feed hopper 35, the fermenting agent will enter the feed channel 311 through the feed hole 312. The centrifugal force generated by the rotation of the stirring shaft 31 will throw the fermenting agent in the feed channel 311 out of the discharge hole 313, thereby further improving the uniformity of the mixing. When the fermentation liquid is discharged through the drain pipe 5, after passing through the first spiral blades 33, the discharged fermentation liquid can form a spiral, thereby improving the discharge efficiency.

[0037] In one embodiment, see Figure 2 and Figure 3 A cleaning component 36 is provided on the stirring shaft 31. The cleaning component 36 includes a cleaning frame 361, which is equipped with a detachable rubber scraper 362. The rubber scraper 362 abuts against the bottom of the mixing chamber 21. The end of the rubber scraper 362 that gradually approaches the stirring shaft 31 gradually tilts to one side, so that when the rubber scraper 362 scrapes the fermentation liquid at the bottom of the mixing chamber 21, it can push the fermentation liquid toward the drain pipe 5. In practical application, the cooperation between the cleaning frame 361 and the rubber scraper 362 facilitates the installation and removal of the rubber scraper 362. With the rubber scraper 362, the bottom of the mixing chamber 21 can be scraped, thereby preventing fermentation liquid residue from remaining at the bottom of the mixing chamber 21.

[0038] The cleaning frame 361 is provided with an installation groove 363, and a limiting groove 364 is provided at the bottom of the installation groove 363. A limiting strip 365 is provided at the position of the rubber scraper 362 corresponding to the limiting groove 364, and the limiting strip 365 is embedded in the limiting groove 364. In practical application, the rubber scraper 362 can be confined in the installation groove 363 by the cooperation of the limiting groove 364 and the limiting strip 365, so as to ensure the stability of the installation of the rubber scraper 362.

[0039] In one embodiment, see Figure 1 and Figure 2A gap exists between the outer cylinder 1 and the inner cylinder 2 to form a heat-insulating cavity 11. The outer cylinder 1 is equipped with an inlet pipe 12 and an outlet pipe 13 that communicate with the heat-insulating cavity 11. In practical applications, the heat-insulating cavity 11 allows heat-insulating liquid to be introduced into it through the inlet pipe 12 and the outlet pipe 13, achieving a heat-insulating effect on the inner cylinder 2. The heat-insulating liquid can be introduced at the optimal temperature for the growth and reproduction of the microorganisms in the fermenting agent, facilitating the mixing of the fermenting agent and water. A water pump can be installed between the inlet pipe 12 and the outlet pipe 13 to pump the heat-insulating liquid from the bottom of the heat-insulating cavity 11 to the top, thus creating a circulation of the heat-insulating liquid.

[0040] Multiple heating tubes 14 are provided at the bottom of the insulation cavity 11. In practical applications, the heating tubes 14 can be used to heat the insulation liquid in the insulation cavity 11 to ensure the temperature of the insulation liquid.

[0041] A spiral guide plate 15 is provided along the outer wall of the inner cylinder 2 in the insulation cavity 11, forming a spiral flow channel between the surface of the spiral guide plate 15, the inner wall of the outer cylinder 1, and the outer wall of the inner cylinder 2. In practical applications, the spiral guide plate 15 enables the spiral flow channel formed in the insulation cavity 11 to guide the incoming insulation liquid in a spiral manner, thereby improving the insulation effect.
