CITRUS PEEL DRYERS AND WASTE HEAT EVAPORATORS PRINCIPLES OF OPERATION AND TROUBLESHOOTING

In a citrus processing plant the feed mill is the end of the line. What is left over ends up in the feed mill. Peel, rejected fruit, rejected concentrate, clean-up waste, cold pressed oil waste, excess water, and sometimes sticks and leaves. But it is certainly to our industry’s credit that we turn our waste into a […]

ESSENCE RECOVERY, PRINCIPLES OF OPERATION AND TROUBLESHOOTING

During evaporation much of the aroma (or essence) is stripped from the juice as it is being concentrated. It is generally desired to recover a high quality (little damage from heat or oxidation) essence fraction. Essence is considered to be those naturally occurring compounds which form the fraction lighter than water vapor (Some of the […]

JUICE EVAPORATORS, PRINCIPLES OF OPERATION AND TROUBLESHOOTING

HISTORY Commercial evaporation of orange juice began in the late 1940’s. The first evaporators, to produce a product to be reconstituted and used as orange juice, were low temperature-high vacuum evaporators designed and built by B.C. Skinner of Dunedin, Florida. There were several evaporators built on this basis (Frostproof, Auburndale, Dunedin). As operational experience was […]
