Abstract
Abstract A PROCESS AND APPARATUS FOR IMPROVING THE YIELD OF JUICE WHICH MAY BE EXTRACTED FROM A VEGETABLE OR FRUIT PULP. THE PROCESS SUBJECTS THE PULP TO ULTRASONIC VIBRATIONS IN THE FREQUENCY RANGE BETWEEN 20 AND 300 KC/S AT A SOUND INTENSITY OF UP TO ABOUT 20 WATTS/SQ. CM. IT HAS ALSO BEEN FOUND ADVANTAGEOUS TO TREAT EXPRESSED JUICE, WHICH HAS BEEN PRODUCED BY ULTRASONIC MEANS OR OTHERWISE, WITH ULTRASONIC VIBRATIONS, IN ORDER TO IMPROVE THE QUALITY AND FILTERABILITY OF THE JUICE. ALTHOUGH ULTRASONIC VIBRATIONS MAY BE GENERATED IN MANY WAYS IT HAS BEEN FOUND PARTICULARLY SUITABLE TO EMPLOY A SONIC WHISTLE WHICH MAY BE PLACED IN LINE IN CONTINUOUS PRODUCTION EQUIPMENT.
