Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 Shown, a kind of method extracting essential oil from citrus juice peel oil mixture, it comprises the steps:

[0022] a. When squeezing the juice from the cup press 1 installed on the high-level juicing platform, four kinds of materials are directly obtained, namely fruit juice, skin dregs, skins, seeds, and oil-water mixture of skins. The mixture is separately collected and transported by three screw conveyors 2 at different positions, wherein the skin oil-water mixture enters the screw pump 3 collection buffer tank through the screw conveyor 2, and is transported to the screw refiner 4 placed at a high position for skin oil separation; or The skin oil-water mixture collected after the citrus raw materials are oil-grinded is sent to the high-level screw refiner 4 for skin oil separation through coarse filtration and No. 1 pump B1;

Abstract

The invention discloses a method for extracting an essential oil from an orange juicing peel and oil mixture, particularly discloses a way/method for linking a cup juicer and an oil grinding machine, and more particularly discloses an optimal method for mounting and configuring equipment. The method comprises the steps: directly obtaining a peel, oil and water mixture when oranges are juiced by using the oil grinding machine or the cup juicer, and collecting and conveying the peel, oil and water mixture to a spiral refiner for peel and oil separation; then, entering an oil and water mixture into a series of equipment to separate the essential oil in water; and finally, entering the essential oil into an essential oil storage tank, settling the essential oil, and then, flowing the essential oil into a packaging container and the water with very low oil content to enter a sedimentation tank, and entering the water into a spray water pipe of the cup juicer and the oil grinding machine through pumping and pressurizing so as to be recycled. The material delivery of a whole system and the material balance in a delivery process are considered in the method, and the method is convenient to operate, simple in installation and relatively high in water circular utilization ratio. The solid matter content, essential oil content and COD (Chemical Oxygen Demand) in wastewater generated by the peel and oil mixture can be up to the lowest, and the recovery rate of the essential oil in an orange processing process is up to an optimal value.

Description

technical field [0001] The invention belongs to the technical field of extraction methods of food essential oils, and in particular relates to a method for extracting essential oils from citrus juice peel oil mixture. Background technique [0002] Citrus juice is the most traded food in international trade except for grain. With the rapid development of the domestic citrus juice industry and the increasingly stringent requirements for the environment, the skin oil mixture produced during juicing must be perfectly treated, otherwise the waste water Essential oils will cause greater difficulty in wastewater treatment, and will seriously affect the decomposition and utilization of organic matter in wastewater by microorganisms. In addition, with the rapid development of the food industry in China, the demand for citrus flavors is increasing. China currently imports citrus essential oils each year accounting for about two-thirds of the total demand, which invisibly causes citru...
