Embodiment 1

[0015] a. directly take the oil foot with a pH value of 6-7, test the dry basis content in the oil foot and add calcium oxide whose weight is 15% of the dry weight;

[0016] b. Heating to 100°C;

[0017] c. Cool to normal temperature;

[0018] d. Dry in the sun until it can be crushed;

[0019] e. Crushing;

[0020] f. Packaging.

Embodiment 2

[0022] a. Get the soapstock that is alkaline, and add acid to it to neutralize to a pH value of 6 to 7, test the dry basis content in the soapstock and add calcium hydroxide with a weight of 20% on a dry basis;

[0023] b. Heating to 105°C;

[0024] c. cooling;

[0025] d. Dry it with a drier until it can be pulverized;

[0026] e. Crushing;

[0027] f. Packaging.

Embodiment 3

[0029] a. first with embodiment 1 or 2, promptly get the oil residue that pH value is 6~7, test the dry basis content in the oil residue and add the calcium oxide or calcium hydroxide that weight is 15~20% of dry basis weight;

[0030] b. Heating to 120°C in a high pressure reactor;

[0031] c. Cool to normal temperature;

[0032] d. Dry in the sun until the water content is less than 5%;

Abstract

Disclosed is a process for producing fat powder by using oil deposit which comprises, charging alkaline calcium 15-20 wt% of dried oil residue base into the oil residue, heating to 100-120 deg. C, cooling down, drying, and disintegrating. The prepared fatty powder has high fat content, which can be used as feed addictive or fish or shrimp bait.

Description

Technical field: [0001] The invention relates to a method for comprehensive utilization of leftovers in oil industry, in particular to a method for producing fat powder from oil residue. Background technique: [0002] Oil residue is the leftovers produced by the production of vegetable oil, including oil feet and soap feet produced during alkali refining. The weight of acetone insoluble matter-phospholipids in the oil residue dry basis is about 10-60%, and the rest is neutral oil and free fatty acid. At present, the production method using oil residue as raw material can produce two kinds of products, namely industrial acid oil and concentrated phospholipid. The industrial acid oil produced reduces the industrial added value of the product, and the produced one is mainly suitable for the concentration of feed additives. Although phospholipids can increase the added value of products, due to the viscous texture of concentrated phospholipids, poor stability and dispersibility...
