The patented Plate Molecular Still is capable of distilling large quantities of product (10 ton/h and more), under medium- or high-vacuum conditions. The system is suitable for applications involving temperature-sensitive substances, such as oils, fats, pharmaceuticals, vitamins, methyl esters and…
Thin-film drying is a continuous drying technology that is safe, flexible and offers many benefits, including low operating costs, low space requirements and high specific-evaporation capacity Contact agitated dryers are used for drying wet powders, slurries, filter cakes, and applications…
The Model SFT-110 benchtop supercritical fluid extractor is an improved version of this company’s original system. Supercritical fluid extraction is an alternative to traditional extraction methods that use organic solvents. The SFT-110 uses supercritical carbon dioxide and is suitable for…
Featuring a new homogenizer generation, the FrymaKoruma Dinex vacuum-processing unit provides optimal processing times, droplet distribution and product quality. The improved tool geometry enables the product processing time in the homogenizer to be extended and increases the overall efficiency of…
Where do middle boilers go? If you answered, “Nobody knows”, then you’re wrong. FRI’s Design Practices Committee (DPC) knows — and they’re willing to share. The DPC was formed in 1975. It originally contained just six members. Neil Yeoman was…
Among the most widely used technologies in the chemical process industries (CPI), spray drying involves dispersing a liquid or slurry in a hot gas to produce a dry powder product. A wide range of pumpable solutions, suspensions and emulsions can…
A variety of performance problems can arise in distillation towers during startup. Many are caused by equipment, hardware or process conditions. Hardware issues may be related to instrumentation, tower internals or ancillaries. Instrumentation malfunctions are also common during startup and…
Every five years or so, a call would come in and once again I would be troubleshooting a certain extraction unit in Canada — usually in the dead of winter. This particular unit had a liquid-liquid extractor, a stripper, a…
I will bet that many readers are familiar with a Teddy Roosevelt quote that includes the following: “It is not the critic who counts…the credit belongs to the man who is actually in the arena...” Ralph Weiland has been in…
A vibrating fluidized-bed dryer from this company features multiple temperature-control zones that operate independently to permit a variety of different heating and cooling levels in the same continuous-drying system. The unit is ideal for gently drying grains, cereals, dry foods,…
