Problems solved by technology

[0004] The technical problem to be solved by the present invention: Aiming at the problem that the deacidification effect of the current deacidification agent is single and limited, the effective removal of oleic acid cannot be satisfied, and the adsorption process is easy to decompose, a plant alkali loaded on diatoms is provided. On the soil, the method for preparing biomass organic deacidification agent in combination with the cell extract of acid-resistant microorganisms, the present invention firstly pretreats the mandarin turnip, then mixes it with diatomite for extraction, and uses ammonia to diatomite Modification, increase its adsorption capacity, load vinine on diatomite, then cultivate acid-resistant bacteria, then use lysozyme to break the cell wall, dissolve the active substances in it, and finally mix to get deacidification agent , the deacidification agent prepared by the present invention has a good deacidification effect, is stable in the adsorption process, is not easy to decompose, and the preparation process is green and environmentally friendly, and has no pollution to the environment. 0.1%, its adsorption efficiency is 25-30% higher than other deacidification agents

[0017] First, weigh 200g of manjing, remove its leaves and root hairs manually, wash it with water twice, cut the washed manjing into small pieces of 2cm×2cm×2cm, and place the diced manjing in Expose to the sun for 2 days, put the dried mandarin and 100g of diatomaceous earth in a pulverizer for 20 minutes, and pass through an 80-mesh sieve to collect the sieved matter; then add the above-mentioned sieved matter to a beaker filled with 1L of water and heated it to 70°C, then adjusted the pH to 8.8 with 10% ammonia water by mass fraction, and kept the temperature for extraction for 2 hours. After the extraction was completed, the extract was collected and filtered to obtain a filter residue for later use; 15g of glucose and 8g of peptone were weighed , 3g agar, 0.1g potassium dihydrogen phosphate, 0.3g magnesium sulfate and 800mL water, stirred and mixed for 2min, then added a citric acid solution with a mass fraction of 5%, adjusted the pH to 3.5 to obtain a medium, and then a...

Abstract

The invention relates to a preparation method of a biomass organic deacidification agent, and belongs to the technical field of preparation of deacidification agents. The preparation method comprises the following steps: firstly, pre-processing turnip; then, mixing the pre-processed turnip with diatomite and conducting extracting, and modifying the diatomite by virtue of ammonia water, so that the adsorption capacity of the diatomite is enhanced and turnip alkali is loaded on the diatomite; then, cultivating acid-resistant bacteria, and adopting lysozyme to enable cell walls to become broken and active substances to be dissolved out; and finally, conducting mixing, so that the deacidification agent is obtained. The deacidification agent prepared by the invention is good in deacidification effect and stable in adsorption process, and the deacidification agent cannot get decomposed easily; in addition, the preparation method is green and environment-friendly in a preparation process and free from pollution to environment; and the prepared deacidification agent is relatively low in oil loss rate, which is merely 0.1%, in the deacidification process, and the adsorption efficiency of the deacidification agent is improved by 25-30% in comparison with other deacidification agents.

Description

technical field [0001] The invention relates to a preparation method of a biomass organic deacidification agent, belonging to the technical field of deacidification agent preparation. Background technique [0002] Oil refining is to process a certain quality of oil to be refined into finished oil that meets the quality requirements. The essence of this process is to remove the non-neutral oil components in the oil to be refined, so as to obtain relatively pure finished oil, that is, neutral oil. Purification process. Generally speaking, oil refining mainly includes oil filtration, degumming, deacidification, decolorization, deodorization, winterization, dewaxing and other processes. Among them, the oil that has been filtered, degummed, and deacidified is called semi-refined oil, while the oil that has been decolorized, deodorized, winterized, and dewaxed is called refined oil. Generally, unrefined crude oil contains a certain amount of free fatty acid, and the process of r...
