;;; Fox Venturi Eductor for Powder / Liquid Mixing ic Compounding

Fox Venturi Eductors , for blending powders into liquids – have been used in food and beverage manufacturing for over 35 years . They are an ideal way to continuously produce well blended solutions , brines and beverages . Applications of Fox slurry eductors range from adding few pounds per hour of whey added to a milk stream to blending favour additives into liquids flows of 500 GPM or more .
From Batch to Continuous liquid / solid blending with Fox Slurry Eductors The addition of powdered products is often left as a manual operation in otherwise highly automated production environments . Scoops , buckets and bags and their accompanying dust and spillage still often surround powder addition to tanks and vessels , which often require staff climbing ladders with bags on their shoulders .
As plant production rates increase , processes often evolve from batch to continuous , for which Fox Venturi Slurry Eductors are ideal . Liquid flow is maintained at a constant flow rate by the precision machined nozzle within the venturi . A screw feeder can then dose powder – from a bulk bag , bin , or silo – at a controlled rate . For example , Case Study 9 shows the installation at the largest

Some of the largest global beverage manufacturers now use Fox slurry eductors to blend the ever-increasing variety of flavours that consumers are looking for . And a slurry eductor is not limited to powder feed from just one feeder . Up to six feeders can be arranged to deliver powder in different combinations , or one at a time , to meet continually changing production schedules . Fully hygienic CIP ( Clean In Place ) eductors , polished and ground in 316 ss , can be rapidly diassembled
