Production equipment for preparing safflower oil by adopting cold pressing method

Abstract

The invention discloses production equipment for preparing safflower oil by adopting a cold pressing method. The production equipment comprises a screening device, a crushing device, a temporary storage cabin, a tempering and oil pressing device and a crude oil purifying device, wherein the crushing device comprises a double-roll crusher and a first feeder; a material inlet in the upper end of the temporary storage cabin is connected with the double-roll crusher through a scraper blade elevator, a material outlet in the lower end of the temporary storage cabin is provided with a variable-frequency airlock, and the temporary storage cabin is internally provided with a material level device which is in induction connection with a motor; the tempering and oil pressing device is communicated with the material outlet of the temporary storage cabin through a second scraper blade elevator, the tempering and oil pressing device comprises a second feeder, a tempering pot and a double-screw cold pressing machine from top to bottom, a material level sensor in signal connection with the variable-frequency airlock is arranged at the upper part of the tempering pot, and a water sprinkling device is arranged in a material inlet in the upper part of the tempering pot; the crude oil purifying device comprises a slag fetching pond and a horizontal spiral centrifugal machine. Grease and oilseed meals machined by using the production equipment for preparing the safflower oil, provided by the invention, are small in nutrient content and trace element loss, and the production equipment has the advantages that the cost is reduced, and the refining consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of safflower oil preparation, and more specifically, the invention relates to a production equipment for preparing safflower oil by cold pressing. Background technique [0002] The cold pressing process is an oil production process with less impact on the environment. Due to the ultra-low temperature cold pressing technology used in the cold pressing process, the obtained cold pressed oil meets the requirements of direct consumption without further oil refining. After filtration, the finished cold-pressed oil has pure natural characteristics, avoiding the adverse effects of traditional leaching oil processing plants. The cold-pressed finished oil retains the natural flavor and color of the oil, and completely preserves the physiologically active substances in the oil ( Such as vitamin E, sterols), the by-products of oil pressing cold-pressed cake can be pressed twice or used as an important raw material for ...

AI Technical Summary

Problems solved by technology

[0003] The cellulose content of the safflower seed material is as high as 33%, and the shell hardness is relatively high. During the oil pressing process, the high crude fiber content of the seed coat is too high, which causes the temperature of the pressing chamber to rise during the pressing process, resulting in the loss of nutrients and cake in the oil. Protein denaturation in the process, although the above problems can be improved by cold pressing in the prior art, there are still problems in the process of pressing, such as high energy consumption, high cost, and inability to achieve industrialized production.
