Why use a Powder Induction System?
A powder induction system provides an efficient way to deliver dry powders into liquid processes without relying on mechanical conveying directly to the tank. Pre-wetting and incorporating the powder into the liquid stream can help reduce dusting and clumping in downstream tanks while shortening mix and residence times
What Sets Hapman’s Solidquid® Conveyor Apart?
Hapman’s Solidquid combines controlled dry material feeding, powder wetting, and venturi eductor technology in an engineered system. Rather than treating powder introduction as an isolated step, Hapman can integrate upstream equipment such as bulk bag unloaders, bag dump stations, conveyors, feeders, and lump breakers to provide controlled material flow from dry material handling through introduction into the liquid stream. Each system is configured around the material characteristics and process requirements of the application.
Integrate the Solidquid™ with other bulk material equipment from Hapman like the Bulk Bag Unloader, Bag Dump Stations, or PosiPro® Feeder for a complete conveying system.
The Hapman Performantee®
Our Performantee is a 100% operational guarantee that you will be fully satisfied with the performance of our equipment, and that it will achieve the specific results for which it was designed and manufactured. If not, we will revise or repair it to deliver the results we promised.
Product Details
How it Works
Three steps take dry powder from your feeder into your liquid process.
Prepare & Meter
Dry material is conditioned as needed and meter-fed at a controlled rate for consistent introduction into the system.
Wet & Incorporate
The wetting cone brings the powder and motive liquid together, helping reduce clumping before the material enters the eductor.
Entrain & Deliver
The powder eductor creates suction that draws the wetted material into the motive liquid stream for delivery to the downstream process.
Features
Solidquid® shortens mix and residence times, reduces clumping from powders that tend to float, and safely conveys hazardous and explosive powders.
Eductor
Precision-engineered venturi eductor delivers consistent, high-rate material integration.
Washdown
Washdown bowl wets powder before induction to help reduce clumping, buildup, and dusting.
Safety
Helps reduce airborne dust and operator exposure during powder introduction into liquid processes.
MAINTENANCE
Minimal moving parts within the Solidquid induction assembly help reduce mechanical wear and maintenance requirements.
Versatility
Handles a wide range of powders in food, chemical, pharmaceutical, and industrial processes.
Integrated Material Handling
Solidquid® can be supplied as part of a larger Hapman material handling system. Depending on the application, Hapman can integrate equipment for bag or bulk bag unloading, conveying, metering, and controls to provide a coordinated solution from dry material handling through powder induction.

-
What is a powder induction system?
A powder induction system introduces dry powder into a moving liquid stream for delivery to a downstream process. Hapman’s Solidquid™ combines controlled feeding, a wetting cone, and a venturi powder eductor to wet and entrain free-flowing powder into the liquid stream.
Unlike a mixer, Solidquid™ does not perform the downstream mixing operation. Pre-wetting and entraining the powder can help reduce clumping, dusting, and downstream mix or residence times.
-
How does a powder induction system work?
A powder induction system uses a venturi eductor to create suction that draws powder into a moving liquid stream. With Solidquid™, the process occurs in three primary steps:
Prepare & Meter – Free-flowing, clump-free powder is meter-fed into the system at a controlled rate.
Wet the Powder – The wetting cone brings the powder into contact with the motive liquid before it reaches the eductor, helping reduce clumping.
Entrain & Deliver – The powder eductor creates suction that draws the wetted powder into the liquid stream for delivery to the downstream process.The wetting cone and eductor are the heart of the Solidquid™ system.
-
What is a powder eductor and how does it work?
A powder eductor uses the flow of a motive liquid to create suction that draws powder into the liquid stream. In a Solidquid™ system, dry material is meter-fed and wetted before reaching the venturi eductor, where it is entrained into the moving liquid and delivered downstream.
The eductor is selected based on the specific powder, liquid, required feed rate, available pressure, and downstream process conditions.
-
Does a powder eductor mix powder and liquid?
No. A powder eductor is not a mixer. Its function is to entrain powder into a moving liquid stream and deliver it to the downstream process.
With Solidquid™, the powder is pre-wetted before entering the eductor. This can help reduce clumping and facilitate better downstream mixing, but the system does not replace mixing equipment when further blending is required.
-
What types of powders can be used with a powder induction system?
Solidquid™ is designed for dry powders that are free-flowing, free of clumps, and capable of being consistently meter-fed. Material that does not flow reliably can interfere with consistent feeding and may plug the system.
Material characteristics such as bulk density, specific gravity, and required feed rate are evaluated when configuring the powder eductor and supporting equipment. Sugar and yeast are examples of materials commonly used in Solidquid™ applications.
-
Can a powder induction system reduce clumping when adding powder to liquid?
Yes. Pre-wetting the powder before it enters the eductor can help reduce the clumping that may occur when dry powder is added directly to a tank or liquid process.
Solidquid™ introduces the wetted powder into the moving liquid stream before delivery downstream, which can also facilitate better downstream mixing and reduce mix or residence times.
-
Can powder induction systems operate in batch and continuous processes?
Yes. Solidquid™ powder induction systems can be configured for batch or continuous operation. The feeding method, powder eductor, controls, and overall system configuration are selected based on the material and process requirements.
Hapman has configured Solidquid™ systems with both batch and continuous loss-in-weight feeding arrangements.
-
Can a powder induction system integrate with bulk material handling equipment?
Yes. A powder induction system can be integrated with upstream material handling equipment to create a more complete powder-to-liquid process.
Depending on the application, Hapman can integrate Solidquid™ with equipment for bag or bulk bag unloading, conveying, metered feeding, and controls. This allows Hapman to address how dry material is handled and delivered to the point of induction rather than treating the powder eductor as an isolated piece of equipment.
