CLASS 23: Fat Industry.

Sugar.

According to the new process, the oil-containing seeds, kernels and the like become arbitrary crushed and mixed with a boiling solution of 2 to 5 parts of salt in 100 parts of water treated.

Sugar, syrup, or the like would do a similar service, but more expensive and than Part of the residues used as fodder be less beneficial.

Treating the oleaginous fruits with the salt solution can be done while chopping take place in the pan or better, if you have the fruit with a sufficient amount Let the salt solution boil in a cauldron for a short time and then bring it to a Prefswerk, which first the salt water, milky in color, because it contains almost all soluble plant substances leads, already flows out with light pressure, whereupon with stronger pressure one of those Substance-free oil follows, which is stored above the salt water, which later under the OeI is tapped away.

The valuable plant substances contained in this water are filtered off or allowing it to settle and added to the press residues.

The salt water can be used again.

A previously common treatment of the pre-press residues with hot water, among other things To squeeze oil from them was abandoned because the residue is easier to spoil afterwards were subject. On the other hand, they gain in the new process through the dem Salt added to hot water has a long shelf life, it also tastes better for the cattle and becomes better digested more easily than other residues treated without salt, especially than those with carbon disulfide extracted residues from palm kernels and the like.

The removal of oil from the latter, particularly hard fruit, has both to do with the chemical extraction process led as well as the procurement of the most powerful presses, furthermore for the most time-consuming possible crushing of the fruit, which have to be repeated after the first pressing.

All of this is superfluous with the new process, it is sufficient to crush the kernels, simple, cheaper prefabrication is sufficient; a pure oil is obtained, which is made from plant mucilage and albumen has already been separated, residues are obtained, which are caused by the disintegration of the plant cells and the The swelling of the wood fiber gives a more valuable fodder, especially if that with the Plant substances removed from salt water are added back to the feed; the limit of the salary An OeI, which the Prefskuchen should still contain, is with a single pressing without reaching hydraulic pressure.

In the case of edible oils there is the additional advantage that the salt water stains and scratches the skin Tasty substances from the seed coats, which were previously obtained by simply heating the crushed seeds passed into the oil and spoiled its taste, along with the already

absorbs and removes the named plant substances, so that a pure and fine oil is also obtained by pressing once.

Claims (1)

. Patent claim:
The treatment of plants and fruits containing fatty oils with aqueous solutions of salt or of sugar using any proportions and temperatures - with the exclusion of the mentioned treatment of cocoa - for the purpose of easier and quicker extraction of purer oil and the achievement of one when used as fodder more digestible prep residue.
