Embodiment Construction

[0036] according to figure 1 , the citrus fruit juice with the pulp content that needs to be reduced is introduced through an input pipeline 1 at figure 1 In the drum of the disc separator 3 shown schematically by Zhongchun, a pump 2 can be connected in the supply line 1 . The disc separator 3 clarifies fruit juice, preferably citrus fruit juice, wherein the pulp phase containing pulp is continuously output through a first output device and the clarified juice is continuously output through a second output device.

[0037] When the pulp phase (see figure 2 ) is collected in the solids collecting chamber 4 of the separator and passes through the separating disc 5 as a viscous, high-solids-containing, but still flowable phase during operation and as the first output device—that is, the output itself for the output of the liquid The scraper disc 6 of the device is output, while the clarified citrus juice is output as a mobile, lighter phase through another scraper disc 7 as a ...

Abstract

The invention relates to a method for reducing the pulp content of fruit juices, particularly citrus juices, containing pulp, wherein the fruit juice is continuously purified of a pulp phase in the centrifugal field of a separator (3), said pulp phase being drawn from the separator drum through a fluid discharge, characterized in that the density of the pulp phase drawn from the separator is measured using a density flow-through measuring device (14) and that according to said density measurement at least one controllable device (15, 17) is controlled. The density of the pulp phase can be influenced by the control of said device.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for reducing the pulp content of fruit juices, in particular citrus fruit juices. Background technique [0002] It is known to use separators in the manufacture of citrus juice from citrus fruits to clarify the pulp-containing citrus juice. [0003] In the manufacture of citrus juice, citrus fruit is washed, sorted and fed to a juicer, a so-called extractor. The juice coming out of the extractor has a high pulp content which is removed in further processing stages. The pulp grating filter (Finisher) removes the larger stones first. [0004] In order to separate the sand from the juice, if necessary, a hydrocyclone is arranged upstream of the separator. In the next step separate the fine pulp with a separator. Depending on the production step, more or less pulp can be removed. [0005] In order to reduce the number of removals of solids, which always leads to a certain loss of j...
