Method for processing oil press sediment

oil press sediment

The oil press can extract the clear oil from the top, and then accumulate the oil at the bottom of the barrel for natural precipitation. If there is a dedicated storage place, the extracted oil can be stored for a week (that is, natural precipitation). Then the clarity of the oil should be the best. Although the longer the storage time, the better, but if the time is longer, I am afraid it will be superfluous! Filter it with the fine gauze used for the sieve surface. If the amount is small, use a woven bag filled with flour, and if the amount is large, buy another filter pump.

The oil press is a machine that continuously advances the blank in the press chamber and extracts crude oil under the action of dynamic squeezing. In addition to the feed hopper, the press chamber is the main operating part, which consists of a press screw shaft and a cylindrical press cage. There are two types of single-stage pressing and double-stage pressing. The single-stage has only one horizontal pressing chamber, and the two-stage has a direct pressing chamber for the first-stage pressing.

The squeezing screw shaft is composed of a plurality of squeezing screws and pitch rings sleeved on the shaft. Each screw has a certain pitch and depth, and the pitch of each screw on a shaft is gradually shortened from the inlet to the outlet, and the screw depth gradually becomes shallower, so that the volume of the press chamber is gradually changed from the inlet to the outlet. Decrease, the billet enters the press chamber and advances along the snail stage to the exit, and the pressure on it gradually increases, thereby gradually squeezing out the oil. A gasket is installed between the squeezing sliver and the squeezing sliver of the squeezing cage to form an oil gap, and the squeezed out crude oil flows out through this gap.

The squeezing cage of the large screw oil press is also equipped with a scraper. The scraper blade goes deep into the squeezing chamber and is aligned with each distance ring to prevent the blank from slipping in the squeezing chamber and to prevent back blank, and to adjust the thickness of the cake. So as to correspondingly control the press chamber pressure and reduce the residual oil rate. In addition, the machine also has a cake clamping mechanism to make the surface of the slag cake smooth, and is often attached with a steaming pan.

1) When there is too much material in the initial stage of squeezing, the fried oilseeds can be used to slowly feed in, and the mill can be used to remove them repeatedly.

2) During the squeezing process, the material in the press chamber is cut off due to a large amount of material being fed and the press chamber is blocked by oil. Therefore, the feeding should be continuous and uniform. Once the blockage occurs, the power supply should be turned off immediately, the feeding should be stopped, the discharge plate should be opened, the screw shaft should be removed, the oil in the chamber should be removed, and the pressure should be re-squeezed.
