  "abstract": "A process for dry fractionation of fats and oils, by providing a fat-and-oil feedstock having an SFI at 20 DEG C. of at least 15; pre-cooling the fat-and-oil feedstock to a temperature of, at the highest, 3 DEG C. higher than that of a cooling medium to be used for crystallization; allowing the pre-cooled fat-and-oil feedstock to stand while further cooling the feedstock with the cooling medium to form fat crystals and to obtain cakes containing fat crystals; and subjecting the cakes to separation of solids from a liquid phase.",
  "claims": [
    "1. A process for dry fractionation of fats and oils which comprises providing a fat-and-oil feedstock having an SFI at 20° C. of at least 15; pre-cooling the fat-and-oil feedstock to a temperature of, at the highest, 1° C. higher than that of a cooling medium to be used for crystallization; allowing the pre-cooled fat-and-oil feedstock to stand while further cooling the feedstock with the cooling medium to form fat crystals and to obtain cakes containing fat crystals; crushing the cakes; transferring the crushed cakes to a separation step through a pipe line; subjecting the cakes to separation of solids from a liquid phase by a filter press; recycling the liquid phase and mixing the recycled liquid phase with the feedstock.",
    "2. A process according to claim 1, wherein the fat-and-oil feedstock is a laurin fat or oil.",
    "3. A process according to claim 1, wherein the liquid phase is mixed with the fat-and-oil feedstock in a proportion of at least 30% by weight of the total amount of the resultant mixed fats and oils."
