Introduction

The process,exclusively developed by Pennwalt India Limited,for processing Safflower extractions,is capable of producing a protein concentrate having 50-60% O&A from the Safflower extraction having 20-21% O&A.These protein concentrates have therefore found application in compounding cattle feed,as the process is completely devoid of chemical addition,quite unlike the conventional protein isolate processes,wherein the addtion apparently imparts a disaggreable flavour and the isolate is unacceptable as an ingredient in cattle feed compositions.

The Process

The Pennwalt Protein Concentrate Process is based on the premise that the multitudinous cavitational effect of ultrasonics can be used for disintegration of the Safflower Extraction suspended in an aqueous medium to produce fine particles that have substantially more protein levels than in the coarser particles,Thus protein beneficiation is carried out by the purely physical techniques of ultrasonic disintegration primary separation on a vibroscreen fines underflow and thereafter dewatering the vibroscreen on a Decanter Centrifuge.The dewatered cake from the Decanter Centrifuge is then conventionally dried in a convective drier to produce the protein concetrate.The spent hull fraction contains 3.5 to 4.0% protein and the protein concentrate produced has 50%-60% protein.The following flow sheet gives diagrammatic presentation of the process.

Processing Capacity

From 10 tpd to 100 tpd Safflower Extractions.
