RX Vacuum Homogenizer Mixer — Bottom-Entry Homogenizer with External Circulation

The homogenizer enters from the bottom and circulates product outside the vessel through an external loop. It handles high-viscosity products and discharges through the homogenizer itself. The vessel does not tilt.

Where the RX fits

Best for: Toothpaste, high-viscosity cream and ointment — heavier powder loading, finer particle size.

HOW IT IS BUILT

Homogenizer Position & Circulation

This is the one thing that separates RX from the other two series.

HOW IT WORKS

Inside the RX

The main vessel carries a vertical inline high-shear homogenizer mounted from the bottom, plus a wall scraper and two fixed propellers with holes.

The outer anchor agitator turns slowly clockwise, its Teflon blades scraping the wall and lifting product. The two fixed impellers stay still and give the product a counterforce, driving it down into the homogenizing zone and forcing it through the holes in the paddles.

Product enters the rotor from the top opening of the homogenizer, is cut and emulsified through the shear gap, then jets out along the tangent of the rotor into an external circulation pipe that returns it to the top of the vessel. The homogenizer also works as the transfer pump for discharge.

STANDARD BUILD

Materials, Vacuum & Controls

Materials & finish

All product contact parts are made of SS316L, polished to Ra ≤ 0.4 μm. Steam, electric and thermal-oil heating are all available, with jacket cooling — tell us which utility you have and we will build the vessel around it.

Vacuum

A 2BVA series water-ring vacuum pump is fitted as standard, working at -0.08 MPa and pulling down to 33 mbar (97% vacuum). With an air ejector the system reaches 10 mbar. The pump runs on a mechanical seal and stays below 62 dB.

Controls & electrics

Standard build: Siemens PLC with a Weinview HMI touch screen, Delta variable-frequency drives and CHINT switchgear. Prefer another brand? We build to Schneider — and others — on request.

COMPLIANCE

Certification & Documentation

CE / ECM

CE marked. Our range is certified by Ente Certificazione Macchine (ECM), Italy, to the Machinery Directive 2006/42/EC and the Low Voltage Directive 2014/35/EU, against EN ISO 12100:2010 and EN 60204-1:2018 — certificate No. 3J260508.JGMDT35, valid to 07 May 2031.

cGMP

The machine specification complies with cGMP regulations: contact parts in SS316L polished to Ra ≤ 0.4 μm so the vessel cleans down, a spray ball for your CIP cycle, material certificates for traceability, and FAT video before shipment.

Documentation

Every machine ships with its EU Declaration of Conformity, material certificates, hydrostatic test report, FAT video and operation manual.

LIFT

With a Lift, or Without

Two versions of the same machine. The RX is built up to 5,000 L. Up to 2,000 L, you choose: with the hydraulic lid lift, or without. Above 2,000 L — the 3,000 L to 5,000 L sizes — every machine is built with a fixed cover, no lift.

STANDARD

With hydraulic lid lift

Hydraulic lid lift — the lid raises clear of the vessel, so you clean and service it without dismantling
Full access to the agitator, the homogenizer and the vessel wall
Faster batch changeover, easier day-to-day maintenance
Fitted as standard on every size up to 2,000 L
Not offered above 2,000 L — but the machine itself carries on to 5,000 L

OPTION · LOWER PRICE

Without lift

Same vessel, same homogenizer, same emulsifying performance
Lid stays in place — cleaning and service take longer
Lower purchase price
Also available up to 2,000 L
The only version above 2,000 L — every RX from 3,000 L to 5,000 L is built this way

Not sure which one you need? Ask us — we quote both versions side by side so you can compare before you decide.

OPTIONS

Build It Your Way

Standard build is 380V / 50Hz / 3-phase with push-button control. Everything below is available on request.

Fixed cover bolted or welded instead of the lift, to save budget
Alternative slow-mixing part designs
Extra openings on the inline homogenizer for adding hot and cold ingredients and powders
Frame-type slow agitator for the oil pre-mixer
Siemens PLC to automate mixing, dispersing, emulsifying, homogenizing, vacuum, transfer, heating and cooling
Mettler-Toledo load cells
Flow-meter automation for feeding liquid oil and water
Pressure-vessel design for different steam pressures
SIP on request
Power supply other than 380V / 50Hz / 3-phase on request

Trialling a formulation before you commit? Our lab machines run 5 / 10 / 20 / 30 L and are built as floor-standing units — the same technology as the production range, not a benchtop rig.
