Filter Presses Interesting Topi;
The following is taken from George
Dunean's paper on filter presses:
"The simpleat and earliest form of
Juice filters consisted of a cloth bag
into whicA tl,e mice was poured, the
clear jriee passing through, the impuri
tiss Being left behind. Tho results,
however, were far from satisfactory;
the filtration being from the inside, the
finer Impurities wore driven through the
cloth. The bag III a short time became
flied with scum. The next type 10 be
tiled was that inwhieh the filtration
took place from the outside TO the in
side.
ain this tyre the lltcr consisted of
square or round iron vessels with an
iron cover bottled on. The vessel was
divided into certain namber Of cham
bors lined with cloth and kept apart |
by perforated plates, and so construct
cd that the juice could not enter those
chambers without passing through the
cloth. The impurities sank TO the bot
tom Of the filter and the clear juice was
drawn from the different chambers
through a suitable drain pipe. How
ever, the cloth would not retain all the
fine hoating Impurities and in mIst
eases The use OF Juice filters have becn
abandoned, the JUICE being eyaporated
unfiltere6 .s.
