GEA Mechanical Equipmentengineering for a better world Systems and Processes from GEA Westfalia Separator for the Fruit-Processing and Juice-Making Industries [...]... which enzymes are then added and the pulp is mixed into the low-trub juice There is a direct link between pulp fraction, the torque of the screw, the dry substance in the pomace and the differential speed of rotation between the bowl and the scroll The latter determines the dwell time of the mash in the bowl and thus the dry substance in the pomace It is set to the ideal level at the start of processing... juices are known and also licensed as drugs To obtain the juice, the outputs from the decanter and the separator are combined After the plants have been thoroughly washed, they are first chopped, blanched and macerated During the juicing process, the decanter gently separates off the coarser solids before a separator performs fine clarification The juices are then pasteurized and filled The result is... openings in the end of the bowl The liquid flows out between the flights of the scroll to the other end of the bowl The slight impurities still in the liquid are spun out by centrifugal force as the liquid flows through the clarifying zone and is pumped by the scroll to the “solids discharge” point together with the solids which have already been collected in the feed zone The clarified liquid leaves the separation... stage The decanter to be used for these extraction processes is equipped with GEA Westfalia Separator varipond® as standard Process for making fresh plums into juice The decanter can likewise be used to produce juices from fresh plums Following milling and removal of stones, the fruit is juiced directly A high-performance separator then polishes the juice to filling quality The decanter used in the extraction... summarizes the performance data for decanter extraction of juice from apples In addition to the mechanical parameters, the degree of ripeness and temperature of the apples and the addition of enzymes play key roles The values relate to use in the first stage of the GEA Westfalia Separator frupex® process Output is about 25 percent lower in the second stage 3.1.6 Yield Since raw material is often expensive, the. .. this, the fruit is washed, possibly treated with steam and subjected to a subsequent maturing process The fruit is then coarsely milled and heated in a heated screw In countries where it is grown, the fruit is often stored until fully ripe and then cut up by hand The stones are then removed by a 2-stage finisher (strainer) and the flesh strained The purée is heated and the classification process in the. .. chemical compound The result recorded was that the most intensive and best flavor is achieved about ten minutes after the apple has been milled These processes should then be inhibited by thermal pasteurization 11 GEA Westfalia Separator The proportion of stable turbidity is higher than with conventional pressing technology Viscosity, on the other hand, is in the usual range between 1.5 and 2 cStokes If... mash is strained and fed to a decanter The centrifugal forces discharge the solid (pulp) and the liquid (serum) from the decanter separately, allowing them to be processed separately (cf Fig 32) The serum is then concentrated in suitable evaporators and the flavor is recovered The serum and flavor concentrate obtained in this way are mixed back into the pulp from the decanter This process results in... GEA Westfalia Separator varipond ® as standard The extracted raw juice of the first stage (approx 18 – 20˚Brix) is routed via a buffer tank straight to the downstream clarifier for the juice-polishing stage The subsequently clarified raw juice is taken to the evaporator for concentration via a CrossFlow Filtration system The concentrate (approx 70˚Brix) is processed further by the mixing unit and the. .. 2-gear drive to extract juice directly from the pineapple mash This process is based on the GEA Westfalia Separator frupex ® method which uses fewer machines The potential savings are considerable here, and the quality of the end product can also be improved, as the process time at elevated temperature is shorter and associated heat damage and oxidation are reduced considerably 25 GEA Westfalia Separator .
