How to Design a 6-Story Vertical Layout for TCM Extraction?

1.How to arrange a 6-story vertical layout for TCM extraction?

Bad factory layouts waste time and risk product safety. Moving materials across long flat floors is slow. Let us look at how a vertical layout fixes this problem.

You arrange the 6-story layout by function. Floors 5 and 6 hold raw materials. Floor 4 handles washing and cutting. Floor 3 runs the extraction and concentration. Floor 2 holds utility pipes. Floor 1 manages final drying and packing. Gravity helps move materials down.

TCM extraction floor plan and layout design

I always tell my clients at AIPAK ENGINEERING that a smart layout saves money every single day. When we design a TCM (Traditional Chinese Medicine) extraction plant, we must follow strict GMP rules.

A vertical design is the best way to do this. We use gravity to drop materials from one step to the next. This simple trick cuts down on the need for pumps and conveyors. It also stops different materials from mixing up. Let us break down the exact function of each floor.

Floor Level	Main Function	Key Activities
Sixth Floor	Normal Temperature Storage	Storing general herbs, packaging materials, and final extracts.
Fifth Floor	Cool Storage	Keeping sensitive herbs and materials below 20℃with humidity control.
Fourth Floor	Pre-treatment & Feeding	Sorting, washing, cutting, and dropping herbs into extraction tanks below.
Third Floor	Extraction & Concentration	Running water or alcohol extraction, film evaporation, and liquid separation.
Second Floor	Technical Mezzanine	Holding steam pipes, air systems, water chillers, and maintenance rooms.
First Floor	Paste Collection & Drying	Collecting heavy paste, drying the extract, and managing waste air.

This structure keeps dirty jobs away from clean jobs. The technical floor in the middle is very clever. It lets workers fix pipes without entering the clean rooms.

We also calculate the warehouse size based on daily use and supplier delivery times. We use a simple formula to find the safe stock level. This keeps the factory running without running out of herbs.

2.What equipment do you need for TCM extraction?

Choosing the wrong machines leads to low yields and wasted energy. Old equipment simply cannot keep up with modern market demands. You need the right tools for the job.

You need stainless steel extraction tanks for water or alcohol processes. You also need vacuum concentrators to remove water at low temperatures. Finally, you must use centrifuges and filters to separate solid waste from the liquid extract.

TCM extraction tanks and concentration equipment

Equipment selection is the heart of your TCM business. Over the last 15 years at AIPAK, I have seen many companies lose money because they bought the wrong tanks.

For the extraction step, we use 304 or 316 stainless steel tanks. Stainless steel is very easy to wash. If you use alcohol, the tank must be explosion-proof. It must have static elimination lines and gas alarms.

For heating, we prefer steam if you have a boiler. If you do not have a boiler, electric heating works fine.

Equipment Type	Specific Machine	Purpose
Extraction	Stainless Steel Water/Alcohol Tank	Pulls active ingredients from raw herbs using heat and solvents.
Concentration	Vacuum Concentrator	Removes extra water at low heat to protect sensitive ingredients.
Concentration	Thin Film Evaporator	Evaporates liquid very fast for large-scale production.
Separation	High-Speed Centrifuge	Spins the liquid to push solid waste out quickly.

We must calculate the capacity carefully. For example, you might use a 6-cubic-meter tank. You can load 0.5 tons of herbs each time. If you do this three times a day, your daily output is 1.5 tons per tank.

We also use variable frequency drives on our centrifuges. This means the motor speeds up or slows down based on what you need. This change saves a lot of electricity over time.

3.How do you control the environment and safety in a TCM plant?

A bad factory environment ruins your herbs and hurts your workers. Solvents can catch fire, and high humidity causes mold. We must control the air and temperature strictly.

You control the environment by using HVAC systems to keep temperatures and humidity at safe levels. You also need strong exhaust fans to remove steam and dust. For safety, you must install gas alarms, explosion-proof lights, and fire doors.

Safety and clean air protect your business. Herbs are very sensitive to water in the air. If the room is too wet, the herbs will grow mold. We install industrial dehumidifiers and smart air conditioners.

These machines keep the rooms dry and cool. We also have to think about the workers. The extraction process creates a lot of heat and strong smells. We put strong exhaust vents right above the extraction tanks. This pulls the bad air out before it fills the room.

Control Area	Key Action	Benefit
Air Quality	Install dust collectors and exhaust fans.	Removes harmful solvent fumes and herb dust.
Climate	Use smart HVAC and dehumidifiers.	Stops mold growth and keeps workers comfortable.
Fire Safety	Fit explosion-proof lights and gas sensors.	Prevents alcohol vapors from causing fires.
Emergency	Place AEDs, fire extinguishers, and alarms.	Saves lives if an accident happens.

When we use alcohol for extraction, the danger goes up. Alcohol vapor can explode easily. I always make sure our layout includes gas monitors.

If the alcohol in the air gets too high, the alarm rings. The system then turns on emergency fans automatically. This fast action stops disasters.

4.How to save energy and treat waste in TCM extraction?

High energy bills and waste fines will destroy your profit. Throwing away hot water or dirty air is burning money. We have to recycle heat and clean the waste.

You save energy by using heat exchangers to capture hot steam and warm up cold water. You treat waste by cooling exhaust steam into reusable water. You also use biological tanks to clean dirty water and collect herb waste for fertilizer.

Energy saving and waste treatment in pharma plant

Making TCM uses a lot of steam, electricity, and water. I always push my clients to use energy recovery systems. It costs a little more at first. It pays back very fast.

When hot steam leaves the extraction tank, we do not let it fly away. We catch it in a condenser. This turns the steam back into hot water. We use this hot water to clean the tanks or heat the next batch.

System Type	Technology Used	Result
Energy Saving	Heat Exchangers	Transfers heat from waste steam to fresh water.
Energy Saving	Cooling Storage Pool	Makes ice at night to cool tanks by day.
Air Treatment	Carbon Filters & Water Sprays	Cleans solvent smells and traps dust.
Water Treatment	Biological Sludge Pools	Uses good bacteria to eat organic waste in dirty water.

Another great trick is the cooling storage pool. Electricity is usually cheap at night. We use machines to cool a large pool of water at night. During the day, we pump this cold water to cool down the hot extract. This cuts cooling costs by about 35%.

For solid waste, we never just throw the boiled herbs away. We sell the herb waste to farms. They use it to feed animals or make organic fertilizer.

5.How do you prevent microbial contamination in TCM extraction?

Bacteria and mold will ruin your final product. If your equipment has dead corners, germs will grow fast. You must stop contamination before it reaches the patient.

You prevent contamination by using smooth 316 stainless steel equipment with no dead corners. You must clean and sterilize machines with hot water or chemicals daily. Workers must wear clean suits, and the water used for production must pass strict UV sterilization.

Microbial control and cleaning in pharma cleanroom

Germs are the biggest enemy in a pharmaceutical plant. They can come from the raw herbs, the air, the workers, or dirty water.

At AIPAK ENGINEERING, we build our machines to fight germs. We make sure every tank and pipe has a smooth inside. We do not leave any sharp corners where old paste can hide. If paste hides, bacteria will eat it and grow fast.

Source of Germs	Prevention Method
Raw Herbs	Test herbs before they enter the warehouse. Keep storage dry.
Equipment	Use CIP (Clean-In-Place) systems. Wash with hot water and safe chemicals.
Factory Air	Use HEPA filters to clean the air. Keep humidity low.
Workers	Train staff to wash hands. Use full cleanroom suits and masks.
Water Supply	Test water daily. Use UV lights or ozone machines to kill germs in water.

Cleaning is not just spraying water. We write strict cleaning rules for our clients. They must do a daily clean, a weekly deep clean, and a monthly inspection.

After chemical cleaning, we test the equipment. We must make sure no soap is left behind. The water we use to make the medicine is also filtered many times. We use UV light to kill any tiny bugs in the water before it touches the herbs.
