Main Components

1. Drying Chamber

The core area where fluidization takes place.
Made of stainless steel with high heat resistance and corrosion protection.
Includes sieves or perforated plates that hold the materials while allowing hot air to pass through.

2. Blower System

Generates high-pressure airflow to move the material and create the fluidized state.
Equipped with air filters to ensure clean air enters the chamber.

3. Heater

Usually electric or gas-heated, supplying thermal energy to the incoming air before it enters the drying chamber.

4. Spray System

Used to spray binder solutions or other liquids onto the material to aid granulation.
May feature top-spray or bottom-spray designs depending on the machine configuration.

5. Exhaust Air Filter

Removes fine dust before releasing air into the environment, ensuring compliance with environmental standards.

6. Control Panel

Allows operators to run and monitor the drying process, adjusting parameters such as temperature, airflow, spray rate, and drying time.

7. Product Discharge

The outlet where the final dried or granulated material is collected.

Working Principle

• Fluidization

When heated air is blown through a layer of material (powder or granules), it creates a “fluidized” state, causing the particles to move as if they were a flowing liquid.

• Drying

The hot air evaporates moisture inside the material, reducing the moisture content to the desired level.

• Granulation

A binder solution is sprayed during fluidization, causing powder particles to agglomerate into uniformly sized granules.

CX-200 Herbal extractor & concentrator system by T&T MACHINERY is manufactured with advanced Japanese technology, designed to save solvents, preserve active ingredients, and operate fully automatically according to GMP standards.

Introduction to the Herbal Extractor and Concentrator System

The Herbal Extractor and Concentrator System is specialized equipment used in the pharmaceutical, traditional medicine, and functional food industries. It extracts active ingredients from medicinal herbs and then concentrates the extract to obtain a solution with a high concentration of active compounds, saving solvents and improving production efficiency.

Main Components

• Extraction Tank: Heats the herbs with solvents (such as water, ethanol, methanol, etc.) to extract the active ingredients.

• Condenser: Cools down the vaporized solvent and condenses it back into liquid form.

• Solvent Recovery Tank: Collects the condensed solvent for reuse in the extraction process.

• Concentrator: After extraction, the solution is transferred to the concentrator (usually a vacuum concentrator), which evaporates part of the solvent, thickening the extract without damaging heat-sensitive active ingredients.

• Vacuum Pump: Lowers the pressure to reduce the boiling point, allowing extraction and concentration at lower temperatures, thus protecting sensitive compounds.

• Automatic Control System: Monitors and adjusts temperature, pressure, and processing time.

Working Principle

• Extraction:
  The herbs are cooked in the solvent → active compounds dissolve into the solvent → forming the herbal extract solution.

• Solvent Recovery:
  The solvent vapor is cooled down → condensed back into liquid → collected and circulated back to the extraction tank for reuse, saving solvent and reducing environmental impact.

• Concentration:
  The extract solution is transferred to the concentrator → excess water or solvent is evaporated under reduced pressure → producing a concentrated extract with a high content of active ingredients.

🧾 Dry Herbal Extract Grinder – Introduction

The Dry Herbal Extract Grinder is a vital piece of equipment in traditional herbal medicine (Eastern medicine) production. It is specifically designed to grind dry herbal extracts (concentrated extracts that have been dried) into fine powder, which is then used in the formulation of products such as pills, tablets, powders, granules, etc.

⚙️ Main Components

A standard Dry Herbal Extract Grinder is composed of the following key parts:

🔸 Feed Hopper

• Where the dry extract material is loaded into the machine.

• May be equipped with a regulating valve to control the feeding rate.

🔸 Grinding Chamber

• The core part containing the grinding mechanism, which may consist of:

  • Hammer blades (for hammer mills)

  • Rotating pins (for pin mills)

  • High-speed air jets (for jet mills)

🔸 Filter Screen / Sieving Mesh

• Installed inside the grinding chamber.

• Functions to separate and allow only fine particles that meet size requirements to pass through.

🔸 Suction Fan or Dust Collector (if applicable)

• Extracts the fine powder after grinding.

• Helps collect the powder efficiently and reduces material loss.

🔸 Electric Motor

• Powers the grinding mechanism.

• Often paired with a gearbox or inverter to control speed.

🔸 Machine Frame and Safety Covers

• Made of SUS 304 or SUS 316 stainless steel, rust-proof and GMP-compliant for pharmaceutical use.

🔁 Working Principle

The working principle varies depending on the type of grinder. Below are typical examples:

✅ Hammer Mill Principle:

• Dry extract is loaded via the feed hopper.

• Hammer blades rotate at high speed (several thousand to tens of thousands of RPM).

• The hammers impact the material, breaking it into smaller fragments.

• Continuous impact and friction further reduce the size.

• Once the powder is smaller than the mesh holes, it passes through the screen and is discharged through the outlet.

✅ Ultra-fine Grinding (Pin Mill / Jet Mill):

• Utilizes high-speed airflow or electrostatic impact to break down the material.

• Generates minimal heat, ideal for preserving sensitive active ingredients.

• Achieves extremely fine particle sizes (as small as 10–50 microns).

Introduction to the Blister Packing Machine

The Blister Packing Machine manufactured by T&T MACHINERY is a specialized device used in the pharmaceutical, nutraceutical, and various other industries to package products into blisters. It automatically seals capsules, tablets, and film-coated tablets into individual blister pockets, ensuring cleanliness, accurate counting, and convenience for both usage and distribution.

💡 Basic Operating Principle of the Blister Packing Machine

• Film Feeding (PVC/PVDC/Aluminum): The roll film is fed into the machine.

• Heating: The plastic film is heated to soften and formable condition.

• Forming: The forming mold creates individual blister pockets.

• Product Feeding: Tablets or capsules are automatically filled into each pocket.

• Sealing: Aluminum foil or plastic film is sealed onto the blister surface.

• Cutting: The machine automatically cuts the blister sheets to the desired size.

📦 Benefits of Using a Blister Packing Machine

• Ensures products are tightly sealed, preventing contamination, dust, and moisture.

• Allows easy counting and distribution of products.

• Enhances the professionalism and appearance of the packaging.

• Suitable for large-scale GMP-compliant production lines.

Herbal Washing Machine

The herbal washing machine is a crucial device in traditional herbal medicine production lines. It ensures that the raw materials are clean and free from soil, impurities, microorganisms, etc., before entering subsequent stages such as cutting, drying, extraction, and more.

Construction of the Herbal Washing Machine

• Washing Tank: Features a drain outlet or is designed as a horizontal cylindrical tank.

• High-Pressure Water Spraying System: Equipped with nozzles for high-pressure water jets, or air pipes to generate strong aeration.

• Agitators or Conveyors: May include paddles or conveyor belts to evenly stir the herbs during the washing process.

Working Principle

• Raw materials (roots, stems, leaves, etc.) are fed into the machine.

• Water, sometimes mixed with ozone or a mild disinfectant solution, is sprayed or aerated at high pressure to dislodge soil and contaminants.

• Some machines include a filtration and water recirculation system, helping to save water and protect the environment.
