Problems solved by technology

[0009] However, the structure of the basket of the prior art devices is subjected to unevenly distributed stresses during the scraping operation and, over time, the unevenly distributed stresses can cause premature wear of the device, more specifically the rotating mechanism, i.e. the motor, the rotating Shafts, bearings…

Embodiment Construction

[0026] The invention relates firstly to a batch centrifuge 1 , in particular to a centrifuge for separating molasses from sugar crystals in massecuite.

[0027] The centrifuge includes at least the following elements:

[0028] - a centrifugal drum 2 for containing the product to be treated and having a permeable wall 40,

[0029] - a plurality of motor means 3 for driving the drum 2 in rotation around a vertical axis of rotation,

[0030] - An unloading device comprising means for scraping the permeable inner wall 40 of the drum.

[0031] According to the invention, said means for scraping the wall 40 consist of a set of at least two scoops 5, 6 distributed inside the drum and articulated in rotation about at least one vertical axis.

[0032] Such as figure 1 As shown, according to one embodiment, the drum 2 is housed in a vertically arranged cuve 15 , supported in particular by a coaxial axis of rotation 7 . The motor arrangements 3 , in particular electrical arrangements...

Abstract

The invention relates to a discontinuous centrifugal machine (1) which is intended, in particular, to separate molasses from sugar crystals in a masse-cuite. The invention comprises at least one perforated centrifugal drum (2) which is intended to receive products to be treated and which is equipped with a permeable wall (4), motor means (3) for rotating the drum (2) around a vertical axis of rotation and discharge means including means for scraping the permeable wall (40) inside the drum. According to the invention, the wall-scraping means comprise an assembly consisting of at least two spades (5, 6) which are distributed inside the drum (2) and which are articulated such as to rotate at least around a vertical axis.

Description

technical field [0001] The present invention relates to a batch centrifuge, and more particularly to a centrifuge for separating molasses from sugar crystals in massecuite. Background technique [0002] In the field of industrial processing of sugar, batch centrifuges are known. These devices consist of a perforated rotating basket - also known as a centrifugal drum - which is capable of being loaded with massecuite products. [0003] The basket is driven in rotation by means of an electric motor in order to separate the molasses from the sugar crystals through a perforated surface - in particular a sieve - in particular by means of a refining plant. [0004] The syrup refiner - consisting of one or more tubes arranged in a drum - is capable of washing the crystals in the basket with syrup, water, or even steam. [0005] For handling, the lower surface of the basket is opened and the rotating basket is emptied of product by means of an unloading device. [0006] The unloa...
