Description

Strip type oil press with clear oil

Technical Field

The invention relates to equipment used in grain and oil processing situations. More particularly, the invention relates to a clean oil press used in grain and oil processing.

Background

The existing oil pressing modes generally comprise hot pressing and cold pressing, wherein the hot pressing (cooked pressing) is that before oil pressing, oil materials are subjected to high-temperature heating treatment, so that a series of changes occur inside the oil materials: the oil extracted by the process has pure taste and rich oil fragrance; however, the process has the disadvantages that the color of the squeezed oil is dark, the acid value is increased, and the oil is easy to silt in frying east and west. And some of the nutrients in the oil (vitamin E, sterols, carotenoids, etc.) are lost to the high temperatures generated by hot pressing.

The cold pressing method (raw pressing method) refers to an oil pressing process in which oil is sent to an oil press to be pressed in a low-temperature state without being heated or slightly heated before being pressed. Cold pressing processes are generally carried out in an environment below 60 ℃. In order to improve the quality of cold pressed oil, the raw materials for pressing oil generally need to be refined. The cold-pressed oil has low temperature, low acid value and high quality, the natural flavor and color of the oil are retained in the cold-pressed finished oil, the nutritional ingredients in the oil are completely preserved, the protein denaturation degree is low, and the comprehensive utilization of the protein is easier. Generally, cold pressed oil has a low smoke point, is not easy to cause silting, has a clearer color, is better in color and luster when compared with hot pressed oil, and has the defects of long manufacturing process time, trouble and low yield when compared with hot pressed oil.

Therefore, under the normal condition, the squeezing modes of different raw materials need to be distinguished according to different raw materials, although the existing equipment can realize squeezing and filtering in one piece of equipment, the existing equipment cannot be matched with equipment for realizing hot squeezing or cold squeezing simultaneously, the squeezing modes of different modes have better filtering effects, the filtering effects of the equipment are usually finished by adopting a positive pressure or negative pressure mode, the filtering mode has high requirements on the slag content of oil after the equipment is squeezed, if the slag content is too high, slag in a filter screen of the equipment needs to be removed manually in time, otherwise, the filtering effect or the processing speed of the equipment can be influenced, and meanwhile, in the filtering process, oil products are exposed, easily cause pollution and are not beneficial to quality improvement.
