A hydraulic combined steam leaching type integrated edible oil press and a method for processing edible oil with the press

Abstract

Disclosed are a hydraulic combined steam leaching type integrated edible oil press and a method for processing edible oil with the press. The invention belongs to the field of edible oil processing. The invention solves the problems of low oil yield, residual harmful substances and poor economic efficiency in the existing pressing production process. The invention includes the comprehensive utilization of two functions of hydraulic pressure and leaching. Method: 1. Crush the oil plant, and then put it into the press from the feed port; 2. Send steam into the oil plant through the water vapor hole on the oil-water-vapor separation partition plate, and the oil outlet at the lower part of the press chamber will start to drip. Stop sending steam and keep warm at 85-100°C; 3. Start the press, set the pressure and propulsion speed of the hydraulic cylinder, and press oil at a constant temperature of 85-100°C until the oil is discharged from the lower part of the press chamber. 4. Unload the pressed oil cake, and then reinstall the oil-water-vapor separation partition into the press. Pushing the push plate through the hydraulic cylinder to extract oil, combined with high-temperature steam leaching, the oil yield can reach more than 18%.

Description

technical field [0001] The invention belongs to the field of edible oil processing, in particular to a hydraulic combined steam leaching type integrated edible oil press and a method for processing edible oil with the press. Background technique [0002] At present, there are two main methods of producing edible crude oil: pressing and leaching: [0003] The first pressing method (belonging to the first generation, inherited from ancient times) mainly includes hydraulic pressing and screw pressing: [0004] 1. Hydraulic pressure: In order to use a hydraulic press to press oil through a hydraulic method, the press has been using vertical and vertical extrusion since ancient times, using iron plates and steel rings as intervals. It mainly includes the following disadvantages: First, the method of vertical extrusion requires manual feeding one by one, the operation is time-consuming and laborious, the labor cost is high, the efficiency is low, and industrial production cannot ...

AI Technical Summary

Problems solved by technology

It mainly includes the following disadvantages: First, the method of vertical extrusion requires manual feeding one by one, the operation is time-consuming and laborious, the labor cost is high, the efficiency is low, and industrial production cannot be formed; the second is that iron plates and steel rings are used as intervals , there is no oil passage, resulting in no oil when the extrusion is light, and the density of the oil increases when the extrusion is heavy, and the resistance of the oil in the center to penetrate outward becomes larger, and the oil yield is only about 12%, which is low.

It mainly includes the following disadvantages: First, the extrusion is light and the oil yield is low, and the extrusion is heavy and the temperature is high, which leads to the oil and cake color being too dark, which affects the product quality and increases the difficulty and cost of deep processing. At the same time, the oil yield is not high. , only about 13%; the second is high power consumption, about 80 degrees of electricity is needed to squeeze one ton of oil, and the economy is poor

[0007] In addition to the above two production processes, there is currently no third production process in the world's edible oil production process
