Description

Strip type oil press

Technical Field

The invention relates to equipment used in grain and oil processing situations. More particularly, the invention relates to a bar press for use in the context of 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 to cause a series of changes 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 extracted oil is dark, the acid value is increased, and the oil is easy to become silted when being fried in 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) is 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 material of pressed oil generally needs 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 silt, has a clearer color, is better in color and luster than hot pressed oil, and has the defects that the production process is long, so that the yield is low compared with that of hot pressed oil.

Therefore, under normal conditions, the squeezing modes of different raw materials need to be distinguished, the existing equipment cannot realize hot squeezing or cold squeezing simultaneously in one piece of equipment, the integration among the equipment is poor, and the occupied area is large.
