RB Vacuum Emulsifier Mixer — Separate Emulsifying Pump for Low-Headroom Plants

The homogenizer is an independent emulsifying pump piped to the vessel bottom — a horizontal inline machine that stands beside the tank, not above or below it. That makes it the right choice when headroom is limited, and because the pump is a separate unit, maintenance is easier than on the other two types. Two agitator types are combined. The vessel does not tilt as standard, but can be built to tilt on request.

Where the RB fits

Best for: High-viscosity cream, ointment and toothpaste — especially where ceiling height is limited.

HOW IT IS BUILT

Homogenizer Position & Circulation

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

HOW IT WORKS

Inside the RB

The homogenizer is a horizontal inline high-shear machine mounted outside the vessel. Pipes run from the discharge valve to the homogenizer inlet, and from its outlet back to the top edge of the vessel.

Inside the vessel a frame agitator turns slowly clockwise; its Teflon blades scrape the wall. One side of the impeller moves product up, the other side moves it down, so the batch rolls over continuously.

Product is cut, sheared and emulsified through the shear gap of the three-layer toothed rotor and two-layer toothed stator, then jets out through the pipeline and returns to the tank for another pass. The inline homogenizer also works as the transfer pump for discharge.

KEY FEATURES

What You Get

Complete process — mixing, dispersing, emulsifying, homogenizing, vacuum, heating and cooling — in one unit
Suitable for cream and emulsion of 10,000 – 100,000 cps viscosity
External emulsifying and homogenizing by horizontal inline homogenizer with pipework
Shorter batch time than the RS series; well suited to large and continuous batches
Cooling system for the mechanical seal inside the homogenizer — allows longer homogenizing time
The inline homogenizer also works as the transfer pump for discharging finished product
Because the homogenizer stands beside the tank, overall height is lower — the right answer when headroom is limited
Servicing the pump does not mean opening the vessel
Variable speed for homogenizer and agitator
Double jackets for heating and cooling; jacket designs for steam, hot water and electric heating
Double temperature probes and controllers
Vacuum system removes air bubbles and transfers ingredients from the oil and water phase tanks
Spray ball ready to connect to your CIP system

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 RB 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 RB 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 with flanged design for a tight budget
Contra-mixing part or other slow agitator designs
Frame-type slow agitator for the oil pre-mixer
Delta, Schneider or Siemens PLC to automate the whole process
Mettler-Toledo load cells
Flow-meter automation for feeding liquid oil and water
