Citrus peel progressive extraction method and citrus peel progressive extraction device

Abstract

The invention discloses a citrus peel progressive extraction method and a citrus peel progressive extraction device, which can recover citrus peel essential oil and citrus kernels by performing pretreatment and progressive extraction on citrus peels. The high-added-value products such as citrus peel infusion syrup, hesperidin, pectin and dietary fibers can be sequentially obtained in the progressive extraction process of the citrus peel, and the method has extremely important economic value; according to the method and the device disclosed by the invention, the extraction of citrus immersion syrup, hesperidin and pectin and the purification treatment of dietary fiber raw materials can be sequentially completed under the condition of not transferring citrus peels, the traditional complicated extraction operation is converted into simple, convenient, systematized and continuous operation, the labor efficiency is greatly improved, and the material and power consumption is reduced; according to the method, a two-time or three-time leaching phase process is adopted, so that the concentration of the extract in the leaching solution is greatly improved, the product recovery rate is increased, the citrus peel is fully utilized in a real sense, and an extremely important new resource is expanded for the development of the food processing industry.

Description

technical field [0001] The invention relates to the technical field of fruit peel recovery and extraction, in particular to a progressive extraction method and device for citrus peels. Background technique [0002] my country's citrus planting area and output rank first in the world. However, the processing utilization rate of citrus is only 8% to 9% and less than 10%, and its utilization rate in citrus juice processing is even lower, which is quite different from the global comprehensive level of citrus processing utilization rate of 35%. The utilization rate of citrus processing in developed countries such as the United States and Brazil is as high as 70% to 80%, which is far from it. At present, China has a citrus juice consumption market with a population of 1.4 billion, and the total consumption is increasing year by year. The annual import of citrus juice is about 80,000 to 100,000 tons. So what is the reason for the large output of citrus fruits in my country, but th...

Problems solved by technology

However, the processing utilization rate of citrus is only 8% to 9% and less than 10%, and its utilization rate in citrus juice processing is even lower, which is quite different from the global comprehensive level of citrus processing utilization rate of 35%.

In fact, citrus juice enterprises cannot get the support of agricultural industry policies to develop citrus orchard bases

Therefore, fruit juice processing enterprises are unable to build raw material bases for citrus orchards. In the face of high citrus raw material prices, the manufacturing cost of citrus juice processing products is out of balance with the input cost of product manufacturing; , it is difficult to meet the product technical requirements, resulting in unstable product quality, and cannot form an influence in the market; third, due to insufficient supply of citrus raw materials, the processing cycle of citrus juice is short, which seriously restricts enterprises from realizing large-scale production; The industrial structure is unreasonable, the processed products are single, and enterprises have no room for maneuver in the face of market changes

Due to the above reasons, for citrus juice processing enterprises that do not have economic strength or have an unreasonable industrial structure, they can only be in trouble for a long time, or even be forced to suspend production or disintegrate.
