How many bags does a 20L decoction machine actually produce?
Start with the pot. A 20L herbal decoction machine boils roughly 14–16 litres of usable liquid per batch after the herbs soak up their share. At 200ml per bag, that is about 70–80 sealed, single-dose bags. At 150ml, it is closer to 100. Run three batches in a day and the range lands between 210 and 300 take-home doses — before anyone on your team touches a pot.
Those are planning numbers, not promises. Thick roots absorb more water than light leaves, so your real output shifts with the formula. What stays constant is the workflow: load the filter cylinder with herbs, set the heat program, and let the machine boil, hold and pack while your staff keeps serving patients.
What a 20L machine with auto packing actually does
This unit is a decoction machine and a packing line in one. It boils the prescription, then seals the finished liquid into labelled, single-dose bags as it runs. No second machine, no transfer between pots, no pouring station.
- Clear glass chamber — you watch the liquid level and the colour of the decoction while it boils, instead of guessing.
- Perforated filter cylinder — herbs stay inside the basket, so stems and sediment never reach the bags.
- Staged decoction mode — decoct first, add later, for formulas where one herb must boil longer before the rest join in.
- Auto switch between strong and mild heat — strong heat brings the pot up quickly, mild heat holds the extraction without burning.
- Digital control panel — set the cycle once and the machine repeats it, batch after batch.
- Drain valve — emptying and rinsing take minutes, not a full strip-down.
If your pharmacy already runs a manual stove and a separate filling funnel, this is the machine that collapses three workstations into one footprint.

Why clinics stop decocting by hand
The switch is rarely about the machine being impressive. It is about the five problems a stove creates every single day:
- Time. A two-practitioner clinic can lose two hours every morning to pots and pouring. The machine runs that block unattended.
- Consistency. Manual decoction changes with the person doing it. A programmed machine repeats the same cycle for every batch.
- Dosing. A sealed bag gives the patient one measured dose. A bowl poured by eye does not.
- Clean-up. One pot, one filter basket, one drain valve. No splashed stove top, no sticky funnels.
- Floor space. One unit replaces the stove, the second pot and the filling station.
Why 20 litres is the size most clinics should start with
Smaller machines, around 10–15L, force you into three or four batches before lunch. Larger units above 30L suit central decoction rooms, not a working pharmacy — they take longer to heat, hold more volume than the day’s prescriptions need, and cost more to clean. The 20L pot sits in the middle: one batch covers a normal morning’s scripts, and two batches a day give a clinic of 100–200 daily doses headroom without overbuilding. If your volume runs higher, order two units instead of one oversized pot — you keep a spare running when the first is being cleaned.
How a clinic runs a 20L herbal decoction machine in a normal day
Most buyers we ship to run the same simple rhythm. Load the filter cylinder with the morning’s prescriptions before the first patient arrives, and start the first batch on the 20L herbal decoction machine. The cycle boils, holds and packs while consultation hours run. By mid-morning the first sealed doses sit ready on the counter. Start the second batch after lunch, and the afternoon’s take-home bags are done before closing. Cleaning is the last five minutes of the shift: drain the chamber, rinse the filter cylinder, wipe the panel. No overnight soaking, no dried residue to scrape off the next morning.
Clinics that run this pattern on a single 20L herbal decoction machine usually keep a spare filter cylinder on hand, so one basket can dry while the other works.
Where this 20L herbal decoction machine fits
Buyers fall into four groups, and the machine serves all of them the same way:
- TCM clinics that want to hand every patient a sealed take-home dose instead of a jar of liquid.
- Hospital TCM pharmacies that process bulk prescriptions on a fixed schedule.
- Herbal pharmacies running a decoction service — the machine turns the service into a repeatable daily routine with predictable output.
- Wellness and rehabilitation centres that prepare batches for in-house patients or day programmes.
What to confirm before you order
Five points settle 90% of the questions we get on this 20L herbal decoction machine. Run through them before you sign anything:
- Voltage. 220V is standard; 110V and 240V are available on request.
- Bag size. 150ml versus 200ml bags changes your daily bag count by roughly a third.
- Daily output target. Your prescription volume decides whether you need one unit or two.
- Spare parts. Most clinics order one extra filter cylinder and hose set so cleaning never stops production.
- MOQ, lead time and packing. These are confirmed in the written quotation, per order.
Frequently asked questions
How many bags can a 20L herbal decoction machine produce in a day?
Roughly 70–100 bags per batch at 150–200ml per bag, and 210–300 bags over three batches. The exact figure depends on your formula and bag size.
Does this machine pack the bags automatically?
Yes. The finished decoction is sealed into single-dose bags by the machine as part of the cycle — you do not fill bags by hand.
What voltage does the machine use?
The standard build is 220V. Tell us your local voltage when requesting a quotation and we confirm the configuration in writing.
How long does one batch take?
It depends on the formula and water volume. Ask the factory for the cycle time based on your standard prescription before ordering.
Can it handle sticky or sediment-heavy formulas?
Yes, within reason. The filter cylinder holds the herbs during extraction, and the drain valve makes rinsing the chamber fast between batches.
What is the MOQ and delivery time?
Both are confirmed per order in the quotation. Volume buyers and clinic chains can ask for tiered terms.
