PerMix News & Updates
Cocoa reactors & processing lives at the intersection of chemistry and craftsmanship. Color, pH, moisture, solubility, and safety all collide inside the same machine—and if that machine isn’t designed for powders under reaction and drying conditions, quality slips fast.
That’s exactly the challenge FPache faced when scaling production. Their answer was not a traditional liquid reactor, but a PerMix Horizontal Vacuum Cocoa Reaction & Drying Reactor—a system purpose-built for reacting, conditioning, and drying cocoa powders in a single, closed process.
Cocoa isn’t a liquid process pretending to be solid. It’s a powder that needs:
Controlled alkalization (Dutch processing)
Precise heat exposure for color development
Moisture removal without flavor loss
Uniform liquid dispersion for instantization
Validated, closed processing for food safety
Trying to achieve all of that with separate mixers, dryers, and sterilizers introduces inconsistency, handling losses, and cost creep. FPache wanted one platform that could do it all.
After evaluating multiple suppliers, FPache chose PerMix because the horizontal vacuum mixer/dryer architecture matched cocoa’s real processing behavior.
1. Uniform Cocoa Alkalization & pH Control
PerMix reactors allow controlled dosing of alkalizing solutions directly into the powder bed while high-efficiency plows or paddles ensure even dispersion. This prevents pH gradients, over-treated zones, and color inconsistency.
Result: reproducible alkalized cocoa across multiple SKUs.
2. Color Development Without Scorching
Cocoa color development is driven by temperature, residence time, and uniform heat transfer. The jacketed horizontal vessel delivers consistent thermal exposure while continuous mixing prevents hot spots.
Result: precise cocoa color tuning—from light brown to deep black—without aroma degradation.
3. Integrated Vacuum Drying
Moisture control is critical after reaction or instantization. Under vacuum, PerMix reactors remove water efficiently at lower temperatures, protecting volatile flavor compounds while accelerating batch cycles.
Result: faster drying, better flavor retention, lower energy demand.
4. Cocoa Instantization & Conditioning
For instant cocoa applications, PerMix reactors support controlled liquid addition, agglomeration, and re-drying in the same vessel. This improves wettability and dispersibility without excessive fines generation.
Result: cocoa that dissolves cleanly instead of floating.
5. Closed-System Sterilization Capability
The sealed, sanitary design supports validated thermal treatment steps for microbial reduction. Combined with vacuum operation, this minimizes oxygen exposure and contamination risk.
Result: food safety compliance without extra handling steps.
One of FPache’s core requirements was staying within budget while scaling capability. PerMix delivered by combining multiple process steps into a single reactor:
Reaction
Heat treatment
Drying
Conditioning / instantization
This eliminated the need for separate dryers, transfer systems, and redundant controls—reducing footprint, maintenance, and operator complexity.
PerMix designs these systems specifically for powder-based food reactions, not adapted liquid equipment. Typical features include:
Horizontal vacuum mixer/dryer construction
Heating & cooling jackets for thermal precision
High-efficiency plow or paddle agitation
Top-mounted vacuum filter to protect the vacuum system
Food-grade sanitary design and cleanability
Scalable designs from pilot to full production
The result is a reactor that behaves the way cocoa behaves—not the way a generic process tank expects it to.
FPache didn’t just upgrade equipment—they upgraded process intelligence. By choosing a PerMix Horizontal Vacuum Cocoa Reaction & Drying Reactor, they gained tighter control over pH, color, moisture, safety, and solubility—all while keeping capital investment grounded in reality.
In cocoa processing, precision isn’t a luxury. It’s the difference between a commodity powder and a premium ingredient.
