Improvements in or relating to the Manufacture of Salt.
1, FRANCISCO PEREZ GUTIERREZ of Cabezon de la Sal, Province of Santander,
Kingdom of Spain, Salt Manufacturer, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The object of the present invention is a combined and economical manufacture
of ordinary melted and moulded salt for flocks or herds utilizing all the heat
coming out of the hearth and passing through the furnace for melting, this heat
being utilized at its issue from the chimney for the production of salt for cooking
purposes by evaporating salt water. For this purpose the greater part of the heat,
which issues from the furnace for melting salt and which would be otherwise lost
in the atmosphere or taken up by the current of air resulting from the draught
in the chimney, is utilized in the first instance, for obtaining evaporation of salt
water, placed in suitable boilers, in order to well utilize the heat in the most
advantageous manner, and to profit by the greater part of the heat after having
melted salt; in this way is obtained at the same time salt for cooking purposes
and melted and moulded salt for animals. As just mentioned, the boilers may be
placed in the most suitable and appropriate manner, near or at the continuation of
the furnace for melting salt, in order to better profit by the heat coming out from
the furnace, where it has at first produced fusion of the salt, which is to be
moulded. It is obvious that in conjunction with this important application of the
heat coming out of the furnace for melting salt, this same heat may be afterwards
used for drying the salt obtained in the boilers by evaporation, and also for applying
to other industrial purposes.
By combining two or more of the above mentioned operations and chiefly that
of fusion and moulding with that of manufacturing salt by evaporating salt water,
great economy is obtained in the cost of production of salt generally.
To the above mentioned combinations, which aim at perfect utilization of the
heat of the furnaces may be added the possibility of using the remains in the
exploitation of mines of rock-salt, even in the case when these remains are soiled,
mixed or not purified by soil of a different nature as by fusion of these are obtained
masses of melted salt of any desired shape, deprived of all impurities, quite suitable
for all animals.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination with a process of melting salt and moulding it afterwards
for the use of animals of the utilisation of the heat coming from the melting
furnaces for manufacturing salt for cooking purposes, by evaporating salt water, in
suitable boilers substantially as described.
2. The combination with a process such as claimed in Claim 1 of either the
utilization of remains of rock salt by transforming them by fusion into masses of
moulded salt separated from impurities, or the utilization in a similar manner of
other kinds of common salt containing impurities substantially as described.
3. The utilization of the heat from a furnace in which common salt has been

page_text: melted either for obtaining in an economical way other products or for applying it
for other industrial uses substantially as described.
