Embodiment Construction

[0015] Ethanol replacement oil production method, the steps are as follows: a. Use ethanol solution with a concentration greater than 95% and a temperature higher than its boiling point as a solvent to infiltrate the cake; b. The cake soaked with the ethanol solution is heated to 120°C by friction and pressure. Fully miscible with the oil in the cake; c. Squeeze to separate the mixed oil for desolventization.

[0016] The ethanol replacement oil production equipment includes an evaporator 1, a condenser 2, and an oil press and a separator. The oil press includes a press cage 3 and a press snail coaxial therein and coaxial with it. The press snail is composed of several joints The squeeze screw body 4 is composed of a squeeze screw body 4 whose internal diameter gradually increases. The front part of the squeeze screw body 4 in the second section and thereafter is covered with an infiltration sleeve 5 whose inner diameter gradually decreases backward, and the squeeze screw body ...

Abstract

The invention relates to an oil preparation method, in particular to an ethanol replacement oil preparation method and equipment for the ethanol replacement oil preparation method, solving the problems of the existing leaching refining method that the energy consumption is large and the quality cannot be guaranteed. Ethanol replacement oil preparation method comprises the following steps of: 1, using ethanol solution with the concentration higher than 95% and the temperature higher than the boiling point as the solvent to penetrate into a cake; 2, heating the cake dipped with ethanol solutionto 120 DEG C by friction and pressure and enabling the ethanol solution and oil in the cake to be mutually dissolved; and 3, performing pressing to separate the mixed oil for desolventizing. The brand new oil preparation method and the matched oil preparation equipment are adopted, so that the solvent turnover is significantly reduced and the energy is saved, in addition, the oil preparation method is more environmentally friendly and safer than the solvent extraction method, the oil quality is effectively guaranteed, no sediment is generated after the oil is heated, meanwhile, the cake quality is also improved, and the cake can be used as raw materials of food.

Description

technical field [0001] The invention relates to oil production technology, in particular to an ethanol replacement oil production method and equipment thereof. Background technique [0002] The leaching method is to apply the principle of extraction, select an organic solvent that can dissolve oil, and make it contact with the pretreated oil—soaking or spraying, so that the oil in the oil is dissolved. This method forms a solution with the solvent and the oil it dissolves, and this solution is called mixed oil. Using the difference in boiling point between the selected solvent and oil, the mixed oil is evaporated and stripped, the solvent is evaporated, and the oil is left to obtain crude oil. The evaporated solvent vapor is condensed and recovered for recycling. [0003] However, the use of leaching method to produce oil has the problem of high energy consumption due to the large turnover, and at the same time, the quality cannot be effectively guaranteed.
