Two Steps, One System: RY-NSG Series Combines Extraction and Concentration in a Single Compact Skid

Look at a typical botanical extraction floor and you'll see the problem immediately: an extraction tank here, a pipe bridge snaking across the ceiling, a single-effect concentrator tucked in the corner, and a maze of transfer lines connecting them all. Every flange is a leak point. Every pump is a residence-time variable. Every meter of uninsulated transfer pipe is energy bleeding into the air. And when you're processing heat-sensitive actives — polyphenols, flavonoids, alkaloids — that thermal exposure between unit operations silently kills your yield.

The RY-NSG Series eliminates the gap. It integrates extraction and vacuum concentration into a single closed-loop skid, so your actives never travel, never cool down, and never degrade between steps.

The Hidden Cost of Separate Units

When extraction and concentration are decoupled, three things happen:

1. Thermal loss — extract liquor cools during transfer, forcing the concentrator to re-heat it. Double the energy, double the thermal degradation.
2. Oxidation exposure — polyphenols and unsaturated compounds oxidize at every transfer point, reducing active content and darkening the product.
3. Solvent inventory — between tanks, pipes, and hold vessels, you're carrying 20–40% more solvent volume than your batch size requires, inflating recovery costs.

The RY-NSG Series addresses all three by keeping the process contained from raw material loading to concentrated extract discharge.

RY-NSG Series: How It Works

Step 1 — Dynamic Extraction

Material is loaded into the jacketed extraction vessel. Solvent (water, ethanol, or mixed) is circulated through the bed by a high-flow pump, maintaining turbulent contact between solvent and solids. Temperature is controlled via the jacket and an in-line heat exchanger with ±1°C precision. Extraction time, temperature, and circulation rate are all programmable.

Step 2 — Direct Vacuum Concentration

Without transferring the extract, the system transitions to concentration mode. The same vessel now operates under controlled vacuum (down to -0.095 MPa), lowering the boiling point to 40–60°C. Solvent vapor rises, is condensed in a shell-and-tube condenser, and is collected in a separate recovery tank. The concentrated extract remains in the vessel — no transfer, no intermediate hold time, no oxidation window.
