THROUGHPUT AND COSTING OF SOFT FRUIT PROCESSING

West Indian Cherry (Malpighia glabra) fruits were harvested, cleaned, and either pressed immediately or frozen. Fruits were either crushed, or thawed and crushed in a one-horsepower stainless steel grape crusher at a rate of 20 kg per minute. The crushed pulp was top-loaded into a 70 1. capacity bladder press, which utilizes water capacity at 3 atm. to expand the bladder, thereby squeezing the pulp. The press capacity is about 230 kg of pulp with a load and press cycle taking 25 minutes. Juice recovery was approximately 65% for fresh fruits and 70% for frozen fruits. Juice was filtered and introduced into either new 2 1. plastic drink bottles or 19 1. lined pails and frozen. A three-person crew was able to complete a crushing, pressing, and filling cycle which produced ISO kg juice in 40 minutes, for a direct labour cost of U.S.5.05 per kg. Press equipment, containers, freezing and building costs are discussed.
