Problems solved by technology

Traditional animal fat processing is mostly based on high-temperature fire refining. The main problems are: 1. The environment of the oil processing workshop is poor, hot, humid, dirty, tired, and smelly; 2. The moisture content and solid content of the finished oil High, not suitable for storage; 3. It is easy to cause fire, and the fire protection is unqualified; 4. The processing is intermittent operation, with low efficiency and high energy consumption; 5. The labor intensity of the workers is high, the working environment is poor, and the environmental pollution is serious.

Embodiment 1

[0025] Cut the raw materials of frozen goods into 0.8mm particles and enter the preheating tank through Jiaolong. After preheating at 100°C for 30 minutes to precipitate the oil, pump the precipitated oil into the melting tank under a negative pressure of 90Kpa. After heating to 90°C and extracting for 30 minutes, it enters the centrifuge for solid-liquid separation, and the separated primary liquid oil passes through the fine filter and enters the finished product tank for storage. The oil content of the separated solid material is 8% after being squeezed by the press, and the finished oil index is as follows: acid value 2.5mgKOH / g oil, moisture 0.5%, color is 6# color, peroxide value 1.5mmol / kg, and negative pressure and low temperature The gas extracted from the smelting tank under extraction is treated by environmental protection equipment and then discharged into the atmosphere. The air in the smelting workshop is fresh and has no peculiar smell.

Embodiment 2

[0027] Grind the fresh raw materials to 0.8mm particles and enter the preheating tank through Jiaolong. After preheating at 100°C for 30 minutes, the precipitated oil is pumped into the melting tank and heated to 90°C under 90Kpa negative pressure to extract After 30 minutes, it enters the centrifuge for solid-liquid separation, and the separated primary liquid oil passes through the fine filter and enters the finished product tank for storage. The oil content of the oil residue is 8% after being squeezed by the press. The finished oil index is as follows: acid value 2.6mgKOH / g oil, water content 0.4%, color 6#, peroxide value 1.4mmol / kg. And the gas extracted from the smelting tank under negative pressure and low temperature extraction is discharged into the atmosphere after being treated by the environmental protection agency, and the air in the smelting workshop is fresh and has no peculiar smell.

Embodiment 3

[0029] Cut the raw materials of frozen goods into pieces and grind them into 0.5mm particles, and then enter the preheating tank through Jiaolong. After preheating at 90°C for 40 minutes, the precipitated oil is pumped into the melting tank and heated to 115°C under 85Kpa negative pressure. ℃, after extraction for 20 minutes, enter the centrifuge for solid-liquid separation, and the separated primary liquid oil passes through the fine filter and then enters the finished product tank for storage. The oil content of the oil residue is 7% after being squeezed by an extruder. The finished oil index is as follows: acid value 2.2mgKOH / g oil, water content 0.6%, color 6#, peroxide value 1.5mmol / kg. And the gas extracted from the smelting tank under negative pressure and low temperature extraction is discharged into the atmosphere after being treated by environmental protection equipment, and the air in the smelting workshop is fresh and has no peculiar smell.

Abstract

The invention discloses a negative pressure production process of additive-free animal oil for feedstuffs, and relates to the technical field of feed processing. The process takes leftovers of live pigs as raw materials, and comprises the following steps of a. taking animal fat raw materials, and mincing the raw materials; b. preheating the minced raw materials until oil materials are separated out; c. putting the separated oil into a low-temperature negative-pressure environment for oil extraction; and d. adding argil into the extracted oil to filter and decolor the oil, then performing solid-liquid separation, taking the separated primary liquid oil as an extracted finished product of the raw material fat, and storing the extracted finished product. The negative pressure production process breaks through the traditional production mode and adopts a negative pressure low-temperature extraction mode, so that the produced oil product is low in acid value, clear in color and luster, easyto store, and free from peculiar smell in the production process; and the continuous product production can be realized simultaneously, thereby achieving the effects of environmental protection and low energy consumption.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to a negative pressure production process for feed without adding animal oil. Background technique [0002] The feed can be divided into plant feed and animal feed according to the source. Plant feed is made by crushing plants, and animal feed is protein feed made from animals or insects. A large number of live pigs are slaughtered and sold in large pig slaughterhouses every year, and the leftovers with little edible value are cooked at high temperature, sterilized, degreased, dried, and finally pulverized to make pork powder feed products. [0003] The production of animal feed from pig waste is to remove grease by heating to obtain oil residue, and then crush, dry, and sterilize the oil residue to obtain feed powder with a suitable particle size. Therefore, in the processing of animal feed, accompanied by In the production of oil residue, animal oil often appears as an ad...
