Preparing Raw Herbs Pulverizing and Slicing

Position Pulverizing and Slicing Before The Decoction Cycle

In a TCM hospital pharmacy or clinic, raw herb preparation dictates the speed and consistency of the extraction stage. Whole roots, barks and dense botanical materials require mechanical reduction before entering normal-pressure or airtight decoction pots.

Slicing and crushing increase the contact surface area between raw herb materials and boiling water. Huayan pulverizers reduce herbs to fineness ratings between 30 and 200 mesh or 60 and 180 mesh, ensuring uniform liquid absorption during decoction.

• Pre-crushing raw materials shortens liquid extraction times and improves consistency across patient prescriptions
• Milling ranges from 50 to 300 mesh accommodate fine powdering as well as coarse slicing
• Balanced slicing mechanisms stabilize raw herb processing before boiling and packing stages

Prevent Thermal Degradation With Water-Cooled Continuous Crushing

Continuous pulverizing creates friction that generates heat inside the crushing chamber. For heat-sensitive herbal ingredients, excessive temperature build-up inside the vessel risks compromising botanical compounds before extraction begins.

The DF-40S desk-top unit integrates water cooling to dissipate process heat during continuous feeding. Built with high-performance alloy steel cutting parts and a stainless steel vessel, it operates with minimal vibration noise inside pharmacy cleanrooms.

• Water cooling limits heat build-up around botanical active compounds during long milling runs
• Continuous material feeding allows sustained throughput without stopping the motor between batches
• Alloy steel crushing components deliver high precision with low vibration noise in clinical settings

High Speed Open Cover Herb Pulverizer DFY-500C is the model most often specified when this is the constraint.

Match Machine Capacity and Speed to Prescriptions Per Session

Selecting between an open-cover pulverizer and a continuous water-cooled unit depends on your prescription batch volume and physical workspace. High-speed batch pulverizers suit intermittent single prescriptions, whereas continuous units handle dispensary production lines.

The DFY-500C open-cover model runs at 25,000 r/min with a 12,000 W motor on an 8.5 kg frame measuring 410 by 240 by 240 mm. The continuous water-cooled model weighs 36 kg on a 600 by 350 by 800 mm bench footprint, running at 5,000 r/min on 2,200 W.

• The compact 8.5 kg open-cover machine handles quick batch milling across small clinic counters
• The 36 kg continuous water-cooled unit delivers 1 to 50 ng/h capacity for ongoing hospital dispensing
• Stainless steel vessels on both units ensure clean and sanitary preparation for liquid medicine decoction

Verify Electrical Connections and Pharmacy Utility Lines

Both pulverizer configurations are rated for 220 V electrical systems. Facilities teams must ensure circuit capacity accommodates either the 2,200 W rating of the continuous unit or the 12,000 W demand of the high-speed open-cover unit.

Water-cooled pulverizers also require adjacent cold-water supply lines to maintain continuous thermal control during operation. Settle utility hookups during the planning phase to avoid delays when machines arrive at your facility.

• Verify that dispensary circuits match the rated 220 V voltage and peak operational wattage
• Position water-cooled units near plumbing connections to maintain cooling flow through the jacket
• Standard benchtop profiles allow direct integration alongside raw material storage and decoction stations
