Detergent mixing tank from China

A detergent tank looks like a simple steel pot, but the wrong agitator whips air in and leaves thick surfactant at the bottom, so the batch foams and varies bottle to bottle.

What you are actually comparing.

Two quotes, one machine name

What hides inside the price

Agitator type

Paddle, anchor, propeller or high shear head. A fast propeller in thin liquid draws a vortex and foam. Ask whether speed is adjustable.

Heating jacket

Some products need heat to dissolve paste or wax. Ask whether the jacket is electric, steam or hot water, and whether it is insulated.

Steel grade and finish

Chlorine and acid cleaners pit some steels. Ask for the grade of every wetted part and the inner surface finish.

Outlet and cleaning

A sloped or conical bottom and a full-bore valve drain the tank. Ask for spray balls, a manway, and how the agitator seal is cleaned.

Before you ask for a price.

Send these with the enquiry. Without them, any number a factory gives you is a guess dressed as a quotation.

Each product with its safety data sheet and the order raw materials go in.
Batch volume and batches per day.
Heating needed, and the utilities you have.
Whether salt is used to thicken, which changes the agitator choice.
How the batch reaches the filler: pump, gravity or a buffer tank.

Turn the claim into a demonstration.

Require this	A pass looks like
Mix a full batch of your thickest product.	Samples from top and bottom match your viscosity and pH limits.
Watch the surface at top agitator speed.	No vortex down to the blades and no more foam than you accept.
Drain and rinse the tank.	The tank empties fully through the outlet and no product remains around the agitator seal.

The documents that must arrive with it.

EU Declaration of Conformity with model and serial number, under 2006/42/EC until 19 January 2027, then Regulation (EU) 2023/1230.
Pressure Equipment Directive 2014/68/EU papers if the jacket runs on steam or the tank works under pressure.
Material certificates for wetted steel.
