Problems solved by technology

For a long time, the oil refining process adopted by my country's animal oil production enterprises is the traditional dry refining or wet refining. During the processing and storage of raw material oil, due to air, temperature, light, moisture, metal ions and oil Affected by factors such as its own fatty acid composition, complex chemical changes will occur, resulting in oxidative rancidity of oils. The acid value and peroxide value of oils are high and not suitable for direct consumption. The acid value of oils is an important indicator of oil quality. One, the high acid value not only deteriorates the flavor and quality of the oil, but also causes harm to human health
Dry refining is smelting under normal pressure, and the raw fat is in contact with the air for a long time. At high temperature, although the Maillard reaction can produce fat-flavored oil, it is dissipated quickly and easily produces oily acid. value, peroxide value exceeds the standard, and the emitted gas has a smell, which has a certain impact on the environment
Wet method vacuum smelting, because direct steam is used for smelting, the oil has a lighter color, but the oil has a high water content. If it is not treated in time, it is easy to cause oil rancidity, and the oil residue has a high water content and becomes a paste. At present, there is no suitable equipment for processing , direct discharge not only pollutes the environment, but also causes waste

Embodiment 1

[0015] a. Pretreatment workshop: Take 8000Kg of raw tallow, after unpacking and sorting, transport it to the crusher, and then transport it to the vacuum melting kettle after crushing; the waste water is sent to the sewage treatment workshop for treatment, and the waste woven bags are sent to the garbage station;

[0016] b. Melting workshop:

[0017] Heat the vacuum melting kettle, open the vacuum valve, control the temperature in the kettle to 65°C, and the pressure at -0.06 Mpa,

[0018] Reduce the pressure for 37 minutes to steam out the moisture in the oil, and then start to heat up. After 5 minutes, the fat will be produced and the oil will be released. Turn off the vacuum equipment, open the intake valve, and turn on the exhaust fan at the same time. Quickly bring the temperature of the melting kettle to 140°C. After fully melting, after 150 minutes, close the intake valve, intermittently intake air and exhaust fan, raise the temperature to 150°C, control the pressure a...

Embodiment 2

[0022] a. Pretreatment workshop: Take 10000Kg of raw beef tallow, after thawing, cleaning and centrifugal dehydration, transport it to the vacuum smelting kettle; the thawing and cleaning wastewater is passed to the sewage treatment workshop for treatment;

[0023] b. Melting workshop:

[0024] Heat the vacuum melting kettle, open the vacuum valve, control the temperature in the kettle to 75°C, and the pressure at -0.062 MPa,

[0025] Reduce the pressure for 35 minutes to steam out the moisture in the oil, and then start to heat up. After 5 minutes, the fat will be produced and the oil will be released. Turn off the vacuum equipment, open the intake valve, and turn on the exhaust fan at the same time. After fully melting, continue to heat up to 150°C, and after 120 minutes at this temperature, intermittently take in air and exhaust the fan, raise the temperature to 165°C, control the pressure at 0.07MPa and simmer for 25 minutes;

[0026] c. Pass the smelted hot oil through a...

Abstract

The invention provides a combined type production technology for refining animal oil and fat. Through a combined type discontinuous vacuum drying and melting matched clean technology, edible animal oil which is good in color, fragrance and taste is produced, production processes of decoloration, deacidification and peculiar smell removal are omitted, exhausted gas is free from peculiar smell, the discharge amount of solid trash and waste water is reduced, the environment is protected, and the production cost is notably reduced.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a combined animal fat refining production process. Background technique [0002] Animal fats include cattle, pigs, and suet. They all have their own unique flavors and are irreplaceable by other vegetable oils. They are widely used in food processing and catering industries, such as hot pot bottoms, fried instant noodles, pastry crisping, and quick-freezing. Food, daily chemical industry soap, processing of soap soap base raw materials, extraction of glycerin, etc. For a long time, the oil refining process adopted by my country's animal oil production enterprises is the traditional dry refining or wet refining. During the processing and storage of raw material oil, due to air, temperature, light, moisture, metal ions and oil Affected by factors such as its own fatty acid composition, complex chemical changes will occur, resulting in oxidative rancidity of oils. The acid...
