Description

Continuous type grease deacidification, deodorization equipment

Technical Field

The utility model relates to an automated production equipment technical field, more specifically the continuous type oil fat deacidification, deodorization equipment that says so.

Background

The grease has various types, the grease components prepared from different raw materials are different, and the physical and chemical properties are greatly different. The grease has high viscosity and poor fluidity and also contains a large amount of free fatty acid (high acid value), and various problems can occur if conventional equipment is used in the production and processing processes, so that the grease quality does not reach the standard, the production efficiency is low and the like. One of the important steps in the processing of fats and oils is deacidification.

Deacidifying can be carried out by adding alkali into oil, neutralizing with acid and alkali to generate soap, and separating oil from soap to obtain deacidified oil. However, when the high-viscosity grease is deacidified by adopting conventional equipment, due to strong viscosity, the alkali liquor and the grease are not uniformly mixed: the excessive alkali liquor not only reacts with acid, but also reacts with neutral oil to cause the loss of the neutral oil; the part with too little alkali liquor can not fully react with acid, so that the acid is remained, and the deacidification effect can not be achieved. Moreover, the soap produced after the acid-base reaction causes a serious emulsification problem with highly viscous oils and fats, making separation of oil and soap very difficult, and a large amount of neutral oil is still entrained in the soap even after long-term sedimentation or centrifugation. Practically, for high viscosity oils and fats, 2.5 to 3% by weight of oil is lost for every 1 acid value reduction (1mgKOH/g) by deacidification with an alkali. For high viscosity grease with acid value of about 30mgKOH/g, 75-90% of grease by weight is lost if the alkali deacidification mode is adopted, and finally the yield of deacidified oil is only 10-25%, thus completely not having economic feasibility. Therefore, for the oil with high viscosity, poor fluidity and high acid value, the cost of deacidification by adding alkali is very high, the process flow is long, the equipment cost is high, the production process is difficult to control, and the method is not economically feasible.

The deacidification may also be carried out by distillation using fatty acids having a boiling point lower than that of the triglyceride to convert the fatty acids into a gaseous state and volatilize the fatty acids from the triglyceride liquid. Because the distillation deacidification only evaporates fatty acid molecules, triglyceride molecules can be completely reserved, so the loss of neutral oil is small, and the method is suitable for deacidification of the oil with high acid value. Theoretical calculations and laboratory tests show that only 0.5% of the fat is lost by distillation deacidification for every 1 acid value (1 mgKOH/g). For the high acid value grease with the acid value of about 30mgKOH/g, if a distillation deacidification mode is adopted, the grease weight is reduced by 15 percent, and the yield of the final deacidified oil is as high as 85 percent, so that the method is very efficient. Therefore, for the oil with high acid value, the distillation deacidification is a more preferable choice.

However, the conventional distillation deacidification equipment has a great problem for the grease with high acid value and high viscosity. The grease with high viscosity has poor self-fluidity, fatty acid in the grease is not easy to flow to the surface, and the volatilization of the fatty acid only occurs on the surface of the grease liquid, so that the grease with high viscosity is caused, the distillation deacidification speed is slow, and the acid value still exceeds the standard after deacidification. The conventional solution is to continuously return the previous deacidification stage to the unqualified oil and repeatedly circulate until the acid value reaches the standard. The method has low efficiency, can only carry out intermittent production, and is not beneficial to improving the production efficiency.
