Description

TECHNICAL FIELD

[0001] The utility model relates to pig fat, in particular to a high -efficient pig fat refining and impurity removing device. BACKGROUND

[0002] Pig fat is an animal oil and fat extracted from the fat tissue of pigs. In industrial production, untreated pig fat is obtained by low-temperature boiling of the fat tissue of pigs. At this time, the pig fat contains natural pigments and other impurities, and its color is usually yellow or brownish yellow. These impurities not only produce an odor, but also easily oxidize to cause the pig fat to deteriorate. Therefore, in order to improve the quality of pig fat and make it have a clearer and more transparent appearance, the pig fat obtained by preliminary boiling needs to be subjected to a bleaching process.

[0003] The existing bleaching device usually pours activated clay into the pig fat and stirs and heats the pig fat, using the property of activated clay to adsorb the impurities in the pig fat, so as to achieve the purpose of bleaching. After bleaching is completed, the pig fat is transported to the next processing equipment. The activated clay, after adsorbing the impurities, will be deposited at the bottom of the reaction equipment. Some pig fat will remain in the sediment. If the pig fat can be squeezed out, the yield of pig fat during the bleaching process can be effectively improved, and the loss of pig fat during processing can be reduced.

[0004] In view of the above problems, we propose a high-efficiency pig fat refining and impurity removing device. CONTENT OF THE UTILITY MODEL
