Method for reclaiming essential oil from condiment disintegration volatilization gas

Abstract

The invention relates to a method to recycle essential oil from the volatile air of the spice grinding. Processing steps of the invention are that the fragrance volatilized in the process of the spice grinding is led into a condensing unit via a fragrance pipeline, a portion of the fragrance is condensed into miscible liquids of water and essential oil, and the other portion of incompletely condensational air is led into the condensing unit via the fragrance pipeline again, and the available composition involved the essential oil in the air is absorbed by absorbing materials. The incompletelyabsorbed air is led in the condensing unit again through a breaker via an air closed-cycle pipeline to recycle and abstract in another circle. After 1-3 cyclic process, the product of spice essentialoil is achieved from the combination of the essential oil separated from the condensational and precipitant miscible liquids of water and oil and the essential oil which is abstracted from the absorbing materials by distillation process. The invention has the advantages of low investment, convenient operation and remarkable economic benefit, economy of energy resources, which is favorable for manufacturers to improve products quality and increase operational income.

Description

technical field [0001] The content of the invention belongs to the technical field of preparation of edible oil and fat products, and relates to a method for recovering essential oil from volatile gas crushed by spices. Background technique [0002] Spices such as Chinese prickly ash, cumin, star anise, etc. are all high-quality seasoning resources, which have high value of seasoning and health care. As essential oils in spices, they have been widely used in food, spices, and medicine for a long time. and other industries. In recent years, with the continuous improvement of people's living standards, the demand for various spices and essential oil products at home and abroad has been increasing year by year. The strong market demand has also stimulated the enthusiasm of farmers all over the world to plant spice crops. The planting area, variety and output are increasing. Take Hancheng City, Shaanxi Province, which was rich in "Dahongpao Zanthoxylum bungeanum" in history, a...

Problems solved by technology

And according to the data obtained from the actual operation, if the traditional grinder is used to crush spices, the higher the essential oil content of the crushed material, the greater the loss of essential oil during the crushing process; the higher the required fineness of the crushed material, the greater the loss of essential oil during the crushing process. Large, most of the spices have a volatile oil content of less than 1% when the crushing fineness reaches 80 mesh, that is, more than 4% of the essential oil (aroma) has volatilized into the air and is lost in vain.

Therefore, the traditional crushing process reduces the content of the effective ingredients (essential oil) of spices after being crushed, causing great losses to producers, consumers and social material resources.

[0004] In the past, in order to solve the problem of the loss of essential oil (aroma) components in spices during the crushing process, out of the desire to reduce the crushing temperature and make the essential oil (aroma) less "run", some people in the field have tried to use water-cooled low-temperature grinder, ammonia-filled Methods such as frozen pulverizer, although the effect of the ammonia-filled frozen pulverizer is better than other methods, it cannot make the essential oil (aroma) in the ground spices non-volatile, and the cost of this machine is expensive, and the operating cost is high. The price of the product is high, and it is far from what ordinary enterprises can afford
