Description

Grease extraction system of animal oil
Technical Field
The utility model relates to a grease extraction system of animal oil.
Background
At present, in the process of extracting animal oil, oil contained in animal fat tissues is mainly extracted, and specifically, the animal oil such as lard, beef tallow, mutton fat and the like is extracted.
Compared with common vegetable oil, the animal oil has irreplaceable special flavor, and can promote appetite of people. They have been used as edible oil for many years, provide energy and nutrition (such as cholesterol) required by growth and development for human bodies, contain a plurality of fatty acids, have equivalent content of saturated fatty acids and unsaturated fatty acids in some animal fat, have higher nutritional value, can provide extremely high calorie, and are particularly suitable for people in cold regions to eat. In addition, fat-soluble vitamin A, D, E, K and carotene are absorbed and utilized only by using fat as a medium. Research shows that when only vegetable oil is eaten without being eaten by animal oil such as lard, the ingested excessive unsaturated fatty acid is easy to be oxidized in vivo, and then a large amount of free radicals are generated, and the oxygen radicals can erode cells to damage DNA, so that cell mutation is caused, and even cancer is caused. Therefore, animal fat and oil are also indispensable nutrient substances for human bodies.
Animal fat is mainly derived from fat tissue obtained by slaughtering and cutting animals, but most of the fat tissue is associated with protein and water. The main methods currently applied to the extraction of the industrial animal fat comprise: direct heating and cooking method, and steaming and cooking method.
The direct heating and boiling method, also called boiling method, releases the grease from adipose tissue cells by heating, which is divided into dry boiling and wet boiling, and has the advantages that after the animal tissue is boiled at high temperature, lipase and oxidase in the tissue can be completely destroyed, even if a small amount of residue exists, the grease can not be rancid, so the method is considered to be a perfect processing method in terms of hygiene.
The specific decocting method comprises dry decocting and wet decocting, wherein the dry decocting is carried out under normal pressure, vacuum and pressure without adding water or water vapor in the processing process. Wet cooking is where the adipose tissue is heated in the presence of moisture, usually at a lower temperature than the dry method. The heat sources of the cooking method are mainly used for direct fire heating, heat transfer oil heating and steam heating, the direct fire heating has great pollution to the atmospheric environment and great harm to operators, and the heat transfer oil heating is facing the trend of being rejected in the field of food processing today when emphasizing food safety. The grease extracting system (device) mainly comprises a cylindrical oil boiling pot, sealing heads are arranged above and below the oil boiling pot, meanwhile, a jacket is arranged on the periphery of the oil boiling pot, a heat exchange coil is arranged in the oil boiling pot, a wing-shaped stirring device is arranged in the oil boiling pot, and the heat transfer effect of materials is good under the stirring effect. When the oil boiling pot is adopted for boiling, the following defects exist:
1. The oil yield is not high, can not fully extract the grease in the adipose tissue, the fine system technology of stewing of effect also can only extract 60 ~ 70% grease in the adipose tissue, when wanting to improve the oil yield again, must improve heating temperature, prolong heating time, this is very uneconomical economically, great increase manufacturing cost, and make solid residue degeneration very severe, the tissue coking, the nutritive value of solid sediment has been reduced, it is most important that the grease that makes the extraction is under long-time high temperature condition, partial fat can decompose, free fatty acid volume in the grease increases, acid value and peroxide value increase very fast, reduce under the quality of grease is serious.
The method has the advantages of high environmental pollution, high pollution and poor operating environment of workers, and can generate certain waste water and a large amount of waste gas regardless of a dry method or a wet method.
And the labor intensity of workers is high.
A boiling method for extracting fish oil or its internal organs includes such steps as mixing animal fat tissue with water, heating for boiling, extracting oil, separating liquid to obtain oil, and discharging waste water. Although the technological conditions of the cooking method are easy to control, simple and practical, the method has obvious defects of low extraction rate, lower oil yield than that of the cooking method, large waste water amount, large waste gas amount and great environmental protection pressure. The temperature is difficult to control when extracting oil by a cooking method, and the quality of grease is affected.
In summary, the current methods for extracting animal oil have the same disadvantages, namely low oil yield, large environmental pollution, high labor intensity of workers, and the like.
The prior extraction process generally finishes extracting the oil in the animal fat tissue in an oil boiling pot, the oil boiling pot has limited extraction capability when being boiled or steamed, the oil yield can only reach 60-70 percent at most under technical and economic conditions without further extraction, and the part of the oil without extraction is wasted in vain no matter the extracted animal oil is used as food or feed or industrial application.
The existing extraction process, no matter adding water or steam into an oil boiling pot, the animal fat tissue raw material contains a large amount of moisture, when oil and slag are separated, the oil and solid slag contain a large amount of moisture, and a large amount of moisture can be directly discharged.
According to the existing extraction process, feeding, oil discharging and slag discharging of an oil boiler are realized, a feeding cover and a discharging door of the oil boiler are manually operated, even the conveying of materials in a workshop is manually operated, some oil boilers are in a mouth dripping type and still need manual stirring by workers, some oil boilers are heated by coal combustion, the workload is increased, and the labor intensity of the workers is generally high.
