Problems solved by technology

However, my country's olive industry has problems such as large planting area, miscellaneous varieties, few suitable areas, and low fruiting rate. The output of olive oil is less than 5,000 tons, and nearly 50,000 tons are imported every year.
Despite this, there is still a lack of high-quality olive oil processing and waste pomace recycling technologies in the world

[0091] The ultrasonic wall breaking fusion device includes a material feed pump, an ultrasonic wall breaking device and a mechanical fusion device; ultrasonic waves refer to mechanical waves with a frequency of about 20 kHz to 50 MHz, and two ultrasonic vibrators are arranged in parallel at the bottom of the wall breaking device. T...

Embodiment 2

[0098] Embodiment 2: rich in polyphenol olive oil processing method

[0099] Design a novel horizontal ultrasonic-assisted spiral centrifuge through Example 1, store fresh olives for no more than 2 days, and obtain fruit pulp through cleaning, debranching and crushing with a hammer crusher, and the beating frequency is 2000~3000r / Min, preferably 2500r / Min, the filter screen of the crusher is 0.5-0.8cm, preferably 0.6cm, and the water content of the fruit pulp is kept at 55-70%. Preferably 2-5 MHz, the ultrasonic power is 1-5kW, choose 3kw, the ultrasonic time is 5-30min, preferably 15-20min, the belt conveying speed of fruit pulp in the ultrasonic wall breaker is 0.01-0.5m / min, preferably 0.05- 0.2m / min fruit pulp transportation accumulation 0.1 ~ 4cm. The fresh olive pulp after ultrasound is continuously conveyed by the screw, the belt conveying speed is 0.10m / min, the pulp is transported and piled up to 1cm, it is mechanically stirred, the stirring speed is 20r / min, and th...

Embodiment 3

[0101] Embodiment 3: Preparation of biological fertilizer by electroosmosis treatment pomace

[0102] In the experiment of electroosmotic dehydration of olive oil waste, olive oil waste was placed between two circular electrodes, the upper titanium plate anode was connected to positive electricity, and the lower stainless steel cathode was connected to negative electricity. A 400-mesh nylon filter cloth is placed on the upper part of the cathode to intercept fine particles in the waste. Mechanical pressure during spin is provided by adding French weights above the piston. Waste pomace is dehydrated by electroosmosis. The dehydration conditions are mechanical pressure of 50-100kPa, voltage gradient of 60-100V / cm, cake thickness of 1cm, dehydration time of 5-20min, and average dehydration power consumption of 0.1-0.3kwh / kg.

[0103] In order to investigate the influence of different mechanical pressures on the electroosmotic dehydration of olive oil waste, this embodiment adopt...

Abstract

The invention discloses a high-quality olive oil processing and waste pomace recycling method. The method comprises the following steps: designing a horizontal ultrasonic-assisted two-phase spiral separator, cleaning and crushing fresh olives, entering an ultrasonic wall breaker for wall breaking, stirring and fusing, and reducing the fusion temperature from 30-40 DEG C to 10-20 DEG C; centrifuging to separate crude oil and water-containing pomace by adopting the two-phase spiral separator, settling the crude oil in a refrigeration house, performing filter pressing with active diatomite, and filtering by a 5-50nm ceramic membrane so as to obtain polyphenol-enriched high-quality special grade virgin olive oil; performing electroosmotic dewatering and compounding on the waste pomace to prepare a bio-fertilizer, performing biological fermentation on wastewater, and preparing fruit wine from the filtrate by virtue of 10-100nm ceramic membrane and pasteurization; and merging all the wastewater in the production process, filtering by a three-level series ceramic membrane of 10-100 microns, performing resin enrichment so as to obtain olive polyphenol extract having the total polyphenol content of more than or equal to 90%, and separating to prepare oleuropein, hydroxytyrosol, oleanolic acid, ursolic acid, maslinic acid, verbascoside, galuteolin and other polyphenol monomer compounds by adopting molecular imprinting directed enrichment and high-speed countercurrent chromatography coupling technologies.

Description

technical field [0001] The invention relates to the comprehensive processing of woody oil forest products and its application in the fields of food, biology and medicine, in particular to the technology of processing high-quality olive oil and recycling waste pomace. Background technique [0002] Olive (Olea europaea L.), an evergreen tree belonging to Oleaceae Oleaceae, is one of the world's famous woody oil tree species. Since the 1960s, Gansu, Sichuan, Yunnan and other places in my country have gradually begun to introduce olives. Longnan City, Gansu Province is one of the largest planting bases of olives in my country. Olive oil is developing rapidly in my country, the planting area is increasing at a rate of 100,000 mu per year, the planting base is more than 1 million mu, and the industrial chain is more than 10 billion yuan. However, my country's olive industry has problems such as large planting area, miscellaneous varieties, few suitable areas, and low fruiting rat...
