Tubular Heat Exchanger 3m

01 · MORE THAN HALF THE CENTRIFUGE

And it is not an extra: it is the condition for it to work

The paste leaving the uncapper arrives cold, irregular and in surges. A density centrifuge needs the opposite: a homogeneous fluid at a steady rate. This is the equipment that turns one into the other.

That is why the order of purchase matters. If density separation is the goal, the real budget is not the €16,314 of the centrifuge: it is that plus the exchanger plus a feed pump with an inverter. Seeing it whole from the start avoids stopping halfway.

02 · 38-42 °C BRUSHES THE RED LINE

And that is what to understand about this machine

The working point is 38-42 °C, and the line above which HMF rises is at 40. The range straddles it. What saves it is that the honey is passing through: it comes in, is heated across a surface and leaves for the centrifuge in minutes, not hours.

So continuous flow is not only about throughput: it is what keeps the exposure short. If the pump beats in pulses, the temperature swings and the honey sits inside longer than it should. And the advice to «nudge it up for heather» is worth taking carefully: above 42 you start paying.

03 · IT NEITHER FILTERS NOR DRIES

And the previous sheet said so, rightly

It does not separate water and it does not remove impurities. Its job is to heat and homogenise, nothing else: wires, splinters and debris are still there at the outlet. Pre-filtering at 3-5 mm before the pump is not optional — it protects pump, valves and a steady temperature.

Nor does it emulsify: the 0.25 kW gearmotor moves the mass slowly, just enough to break lumps and mix cold zones with warm. Transfer is across the surface of the tube bundle, with no contact between the hot water and the honey.

04 · 400 V AND A STEADY FLOW

The requirements to settle beforehand

The connection is 5 kW at three-phase 400 V with a 16 A CEE plug, and internal heating is 4.5 kW with a circulation pump for service water at 60-70 °C. It mounts on the wall, console included, and discharges by gravity to the centrifuge: the mounting height is part of the design.

Feeding calls for a progressive-cavity or flexible-impeller pump with an inverter. On any positive-displacement pump, a bypass valve is essential. And the discharge pipe, DN40 or DN50, short and insulated: what you lose there is exactly what this equipment has just put in.

05 · BEFORE YOU BUY

Add it to the centrifuge and the pump: it is a line, not a part.
