DE3203141A1 - Process and device for cooling massecuite in a vertical crystalliser - Google Patents

Abstract

The massecuite flows through the crystalliser (1) from top to bottom. The tank (2) carries a cooling device (8). The massecuite is periodically raised and lowered again in different ways relative to the tank (2) and the cooling device (8). This is effected by a lifting device (13) which may have an at least partially elastic displacing arrangement (14) with a hollow chamber (17) for charging with a lifting fluid. The lifting fluid can be stored in an elevated storage tank (26). The displacing arrangement (14) can be, for example, an annular tube (15) or a lifting floor (57), and the massecuite can be used as lifting fluid and be periodically pumped into the tank (2) and discharged from it. Rectifying arrangements (51; 101) ensure equalisation of the flow of massecuite over the cross-section of the tank (2). <IMAGE>

Fig. 1 shows a standing mash 1 with a container 2 which, there such mashes are usually placed in the open air, with a lid on top 3 is lockable.

In the lid 3 there is an inlet 4 for the sugar filling compound an interior space 5 of the container 2 essentially completely fills. The sugar filling mass 4 is preferably fed continuously into the container 2. The container 2 has a downwardly tapering funnel 6 at the bottom, at its deepest Place an outlet 7 for the sugar filling mass, which from there via a pump, not shown, is fed to centrifuges in a manner known per se. In these centrifuges the is made from a mixture of syrup and sugar crystals existing sugar filling mass separated into its components. The sugar dispenser kicks in e.g. at 700C through inlet 4 and at 30 to 400C from outlet 7. as Sugar filling compound comes into play in particular, C sugar filling compound or D sugar filling compound Consideration.

Extends into the column of sugar filling compound located in the container 2 a cooling device 8, at the beginning 9 of which a cooling medium, e.g. cooling water, fed from about 20 to 250C and at the end 10 the cooling medium with a temperature from 50 to 600C is omitted. The cooling device 8 has several connected in series flat cooling register 11, each outside of the container 2 by connecting lines 12 are connected to each other.

For the sake of simplicity, most of the drawing figures are cut Walls only drawn as lines, not double-lined with hatching.

At the bottom of the container 2 is a lifting device 13 for the filling compound column intended. This has, as a displacement device 14, an elastic, ring-shaped one Hose 15 with a vertical longitudinal axis 16. A cavity 17 of the hose 15 is via a line 18, a 3-way / 2S-position valve 19 and a line 20 with a first pump 21 is connected. A suction line 22 of the pump 21 is via a 3-way / 2-position valve 23 on the one hand connected via a line 24 to the line 18 and on the other hand via a storage line 25 with a storage container 26 at the upper end of the container 2 connected. To save space and an additional supporting structure is the storage container 26 is arranged concentrically with and in contact with the container 2. The storage container 26 is hermetically sealed when one in the system 17 to 26 located lifting fluid is gaseous. If, on the other hand, one chooses a liquid lifting fluid, a venting device 27 is provided at the top of the storage container 26. That Directional valve 19 is also connected to the storage line 25 by a line 28.

When the pump 21 is running, the cavity 17 is opened in the manner shown in FIG. 1 Plotted flow arrows through the system 18,24,22,21,20119,28 and 25 in the storage container 26 emptied of the lifting fluid.
