• 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:

1. Manifold & Milling Area
2. 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
