MAP Air Cleaning System

Product left inside a mixer does more than create a cleaning task. It extends batch changeovers, occupies operators and delays the return to production. The challenge is particularly significant when processing colourants or managing frequent recipe changes, as residues may remain inside the mixing chamber, inlet pipes, connected valves and underneath the choppers.

The MAP Air Cleaning System automates the removal of residual material from these critical areas. Strategically positioned compressed-air bursts and jets direct residues towards the discharge outlet, helping customers clean the mixer more efficiently and prepare it for the next batch sooner.

The system is available as an option for every mixer size across the MAP WBHT, WBH and WBN ranges.

Main message

Reduce residues, simplify mixer cleaning and accelerate batch changeovers with an automated air-cleaning solution acting exactly where product build-up occurs.

Three reasons to recommend it

1. Faster batch changeovers

The system directs residual material towards the discharge outlet, reducing the amount of product left inside the mixing chamber and simplifying cleaning between production cycles. This provides particular value in processes involving colourants, pigments or frequent recipe changes.

Customer value: less time spent preparing the mixer and a faster return to production.

2. Targeted cleaning of critical areas

Three independent pneumatic circuits clean the points where material is most likely to accumulate:

• Inlet air bursts dislodge powder from the inlet pipes and clean the lower section of the butterfly valves.
• Chopper air bursts break up the ridge of residual material that may form underneath the choppers.
• Chamber air jets remove residues from the chamber, end plates, rotor and mixing tools, directing the material towards the outlet.

Customer value: more effective cleaning in areas that would otherwise require specific manual attention.

3. Less manual cleaning effort

By automating part of the cleaning process inside the mixer, the system reduces the work required to remove residual material from difficult-to-reach areas. Operators can spend less time on repetitive cleaning activities while achieving a more consistent cleaning procedure.

Customer value: reduced manual effort and greater operational efficiency between batches.

How it works

The MAP Air Cleaning System comprises three independent pneumatic circuits positioned at the mixer inlets, underneath the choppers and inside the mixing chamber. Each circuit has its own air reservoir, ensuring that the required volume of compressed air is available when activated.

An optimised blowing sequence coordinates the circuits to balance cleaning effectiveness and compressed-air consumption. The resulting airflow dislodges accumulated product and progressively directs residual material towards the mixer outlet.

The sequence and frequency of the air jets can be tailored to the characteristics of the material being processed and the customer's specific application requirements, helping to optimise residue removal from the mixing chamber

Ideal customer profile

Recommend the MAP Air Cleaning System to customers who:

• carry out frequent product or recipe changeovers;
• process colourants, pigments or products that leave visible residues;
• need to reduce cleaning time between batches;
• want to limit manual cleaning activities;
• experience product build-up in inlet pipes, valves or underneath the choppers.

Sales conversation starter

“How much production time and operator effort are currently required to clean the mixer between batches?”

Follow up with:

• Where does product typically accumulate?
• Are colour or recipe changes extending the cleaning process?
• Do inlet pipes, valves or chopper areas require additional manual cleaning?
• Could shorter changeovers improve the customer’s production schedule?

Value proposition

“The MAP Air Cleaning System automates residue removal in the mixer’s most critical areas. By cleaning inlet pipes and valves, breaking up deposits underneath the choppers and directing material inside the chamber towards the outlet, it helps reduce cleaning effort and prepare the mixer for the next batch sooner.”
