Grease dewaxing equipment

Abstract

The invention belongs to the technical field of grease processing equipment, and discloses grease dewaxing equipment. The equipment comprises a fixed cylinder, and a grease inlet is formed in the top of the fixed cylinder. Through a rubber connecting sleeve and an oil distributing pipe, grease is distributed, then the distributed grease collides in the oil distributing pipe and is gathered again, crystallized wax in the grease collides and is fused with each other, large crystal grains are formed; in the process, cooling water in the fixed cylinder continues to cool the grease distributed in the oil distributing pipe, so that the separation rate of the wax can be accelerated; due to the fact that the diameter of the pipe diameter of the oil distributing pipe is small, the grease in the oil distributing pipe can evenly complete heat exchange with the cooling water, the uniformity of grease crystallization is guaranteed; and due to the fact that an oil guiding pipe and the oil distributing pipe are in a perpendicular state, a large height difference is formed in the perpendicular direction, and then large pressure is formed at the bottom, sufficient pressure is provided for the grease to enter a plate-and-frame filter for filtration, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of oil processing equipment, in particular to an oil dewaxing equipment. Background technique [0002] The oil contains a small amount of wax fat, which will increase the cloud point of the oil, reduce the transparency and digestion and absorption rate of the oil, and make the smell and palatability worse, thereby reducing the edible quality, nutritional value and industrial use value of the oil. Removing and extracting wax from oil can not only improve the quality, nutritional value and oily food quality of edible oil, but also improve the industrial utilization value of oil and comprehensively utilize the wax source of vegetable oil. In the process of dewaxing oil , it is necessary to put the grease into the cooling tank for cooling and crystallization, so that the oil-wax is separated, and then pass it through the plate and frame filter to remove the wax, but the currently used grease dewaxing cooling tan...

AI Technical Summary

Problems solved by technology

[0003] The cooling tank currently used generally has a large internal volume and carries a large amount of high-temperature grease. Since the temperature difference between the cooling water and the grease cannot be greatly different, it takes a long time to cool down, resulting in too long cooling time, which greatly affects dewaxing. efficiency, and, due to the exothermic process during crystallization, it is necessary to cool down the cooling water. If the temperature transfer is not good, it will affect the crystallization efficiency. Therefore, in order to strengthen the crystallization effect of the wax in the oil, it is necessary to stir the oil. If it is not stirred, Only relying on Brownian motion, the cooling effect of cooling water in the grease is too slow, which will lead to too slow crystallization rate. If stirring, the stirring speed should not be too fast. Once the speed is too fast, it is easy to break the crystal grains and affect the crystallization formation, but too slow agitation has little effect on the conduction of temperature in a large amount of oil, which greatly affects the crystallization efficiency
