3. Technical Field

The present invention relates to the manufacturing technology of Cistanche tubulosa extract powder, and specifically to a sieving and dispensing/packaging device for Cistanche extract powder.

 

4. Background

In the fine processing of traditional herbal extract powders (botanical extracts), Cistanche tubulosa extract powder is valued for its unique active constituents and broad application potential. To ensure efficacy and user experience, quality control and particle size distribution control are essential steps in the production process.

However, existing sieving and dispensing equipment for Cistanche extract powder commonly presents several limitations:

Limited impurity separation using simple mesh structures
Many devices rely mainly on basic mesh screening. While particle grading may be achieved to some extent, the separation of impurities from the main powder can be insufficient. In practice, a portion of impurities may pass through with the main powder and enter the final product, reducing purity and potentially impacting efficacy.

Lack of effective agitation causing powder build-up and clogging
Without adequate agitation during sieving, powder may accumulate on the screen, leading to clogging. This decreases screening efficiency, increases the risk of screen damage, and raises replacement frequency. Accumulated powder may also be retained for long periods, increasing the risk of deterioration and quality issues.

Complex structures and inflexible connections affecting cleaning and maintenance
Overly complex structures increase cleaning and maintenance difficulty and may introduce operational safety risks. Inflexible component connections can make disassembly time-consuming-especially inconvenient for equipment requiring frequent screen replacement or impurity removal.

A discharge opening is provided at the bottom of the impurity separation chamber (2), and the sieve plate (3) is fixed on the inner side of the discharge opening. A reinforcement mechanism is arranged on the left side of the impurity separation chamber (2).

The reinforcement mechanism includes the servo motor (4), connecting rod (5), first mounting roller (6), and sawteeth (7). A fine screening chamber (8) is fixed to the bottom of the impurity separation chamber (2). The right end of the connecting rod (5) is provided with an auxiliary assembly for subsequent fine screening.

9.2 Quick-Disassembly Connection Between Hopper and Separation Chamber (Easy Cleaning)

At the four corners of the bottom of the feeding hopper (1), threaded fixing rods (9) are fixedly connected. At the four corners of the upper surface of the impurity separation chamber (2), threaded connecting sleeves (10) are rotatably connected. The bottom ends of the threaded fixing rods (9) extend into the corresponding threaded connecting sleeves (10) and are threadedly engaged.
This connection design allows convenient assembly/disassembly and facilitates cleaning of the feeding hopper (1).

9.3 Material Feeding Path

A discharge pipe (11) is fixed at the bottom of the feeding hopper (1). A feed inlet opening is formed on the upper surface of the impurity separation chamber (2), and the bottom end of the discharge pipe (11) extends into the feed inlet opening.
This ensures smooth transfer of Cistanche extract powder from the hopper (1) into the impurity separation chamber (2).

9.4 Motor Stabilization

A motor stabilizing frame (12) is fixed on the outer side of the servo motor (4). The motor stabilizing frame (12) is bolted to the left side wall of the impurity separation chamber (2), improving motor stability, reducing vibration, and enhancing overall equipment durability.

 

9.5 Sawteeth Layout (Omnidirectional Cutting/Stirring)

There are four groups of sawteeth (7). Each group includes twenty-three (23) sawteeth. The four groups are arranged on the top, bottom, front, and back surfaces of the first mounting roller (6).
This arrangement ensures comprehensive agitation and cutting action during rotation, thereby improving impurity separation.

9.6 Auxiliary Assembly for Fine Screening

The auxiliary assembly includes:

A driving pulley (13) fixed at the right end of the connecting rod (5);

A transmission belt (14) drivingly connected to the driving pulley (13);

A driven pulley (15) drivingly connected to the lower end of the belt (14);

A mounting rod (16) fixed at the center of the driven pulley (15);

A second mounting roller (17) fixed on the outer side of the mounting rod (16);

Four agitation blades (18) fixed on the outer surface of the second mounting roller (17).

The impurity separation chamber (2) communicates with the fine screening chamber (8) through the discharge opening. A screen mesh (19) is fixed inside the fine screening chamber (8), positioned below the second mounting roller (17). The agitation blades (18) promote powder movement and contact with the screen mesh (19), improving fine screening efficiency.

9.7 Shaft Penetration and Transmission Relationship

The right end of the connecting rod (5) sequentially passes through the left wall of the impurity separation chamber (2), the mounting opening of the first mounting roller (6), and the inner right wall of the impurity separation chamber (2), extends to the center of the driving pulley (13), and is fixedly connected to the driving pulley (13).

The left end of the mounting rod (16) sequentially passes through the right wall of the fine screening chamber (8) and the mounting opening of the second mounting roller (17), and is rotatably connected to the inner left wall of the fine screening chamber (8).

The four agitation blades (18) are respectively arranged on the front, back, top, and bottom surfaces of the second mounting roller (17).

9.8 Cleaning Door, Observation Window, and Discharge Door (Operational Convenience)

A cleaning door is arranged on the front side of the impurity separation chamber (2), allowing operators to enter for thorough cleaning and maintenance of the sieve plate (3), sawteeth (7), and related components-supporting hygiene, preventing cross-contamination, and reducing failure rates.

A discharge door is arranged on the front side of the fine screening chamber (8) for convenient collection of the screened Cistanche extract powder.

9.9 Recommended Materials (Manufacturing Considerations)

The impurity separation chamber (2) should be made of stainless steel, which offers excellent corrosion resistance, wear resistance, and ease of cleaning-commonly used in pharmaceutical and food processing equipment.
The fine screening chamber (8) may be made of polymer materials such as polypropylene (PP) or polyvinyl chloride (PVC), which provide good sealing performance, impact resistance, and transparency, and are easy to process and mold.

 

10. Working Principle (Process Flow)

Cistanche tubulosa extract powder is loaded into the feeding hopper (1). The discharge pipe (11) ensures smooth delivery into the impurity separation chamber (2).

After the servo motor (4) starts, the connecting rod (5) drives the first mounting roller (6) and its sawteeth (7) to rotate. The rotating sawteeth generate a cutting/shearing effect inside the impurity separation chamber (2), separating impurities from the main powder.

The separated powder passes through the sieve plate (3) and falls into the fine screening chamber (8), while impurities are retained by the sieve plate (3).

Meanwhile, rotation of the connecting rod (5) drives the driving pulley (13). Through the belt (14) and driven pulley (15), the mounting rod (16) rotates, driving the second mounting roller (17) and agitation blades (18).

The agitation blades (18) stir the powder in the fine screening chamber (8), improving homogenization and increasing contact with the screen mesh (19). Powder that passes through the screen mesh (19) meets the required particle size specification; powder that does not pass remains above the mesh and continues to be stirred and screened.

The final fine-screened powder is collected through the discharge door on the fine screening chamber (8).
