Title: Used Crown Iron Works Model 48 Milling Ring Flash Drying System? | Industrial Drying System

Manufacturer Information

Brand: Crown Iron Works

Model: 48

System Type: Milling Ring Flash Dryer

Condition: Used

Original Application: Food-grade orange pulp

Capacity: 17,000 lbs/hr

Build Type: Industrial Grade

Description
This Crown Iron Works Model 48 Milling Ring Flash Drying System was originally designed and used for drying food-grade orange pulp at 17,000 lbs/hour but is highly versatile and suitable for a wide range of industries and applications. The system is capable of efficiently drying powders, filter cakes, centrifuge cakes, and slurries, particularly when a discrete and fine end product is desired.
The Milling Flash Dryer operates as a low-energy jet mill, utilizing jets of low-pressure air to create inter-particle collisions, which de-agglomerate and break up the feed material without any moving parts in the drying chamber. The torus (donut) shaped design includes two core sections:

Manifold & Milling Area
Classifier Area

The recirculating hot air promotes centrifugal forces that keep larger particles circulating for further drying and milling, while fine particles are extracted with the exhaust gas vapor for collection.

Applications
The Crown Iron Works Milling Ring Flash Dryer is suited for multiple industries and applications, including:

Food Industry

Drying grains, cereals, fruits, vegetables, herbs, and spices
Orange pulp, purees, and food slurries

Pharmaceutical Industry

Drying pharmaceutical ingredients, intermediates, and finished products

Chemical Industry

Powders, granules, and crystalline materials

Mining & Minerals

Ores, concentrates, and mineral powders

Animal Feed

Meal drying and feed additives

Environmental & Waste Management

Drying sludges, biomass, and waste materials

Process Optimization

Ideal for crumbly and free-flowing cakes

System Features

Drying Capacity: 17,000 lbs/hr (based on food-grade orange pulp)

Drying Process: Flash drying with milling ring technology

Feed Material: Crumbly, free-flowing cakes, slurries, filter cakes, and powders

Operation:

Jet mill design—no moving parts in the airstream
Centrifugal force ensures efficient particle size separation
Fine products collected via classifier outlet
Recycles larger particles for continued drying and de-agglomeration

Energy Efficiency: Low energy consumption due to optimized air circulation

Product Outcome: Discrete and fine end-product with consistent moisture removal

Advantages
