Plant drying and essential oil and hydrolat extraction system based on air energy

Abstract

The invention relates to a plant drying and essential oil and hydrolat extraction system based on air energy.The plant drying and essential oil and hydrolat extraction system comprises a drying oven, a condenser, an oil-water separator and an air energy heating and cooling unit.The drying oven is used for drying plants and volatilizing moisture and essential oil in the plants to form oil-water gaseous state mixture.The condenser is connected with the drying oven and used for lowering the temperature of the gaseous state mixture and converting the gaseous state mixture into liquid state mixture.The oil-water separator is used for separating the liquid state mixture into essential oil and hydrolat.The air energy heating and cooling unit heats the drying oven and cools the condenser.Compared with the prior art, the system improves device production efficiency and greatly lowers device energy consumption; due to high system integration, the device site requirements are lowered, the device structure is simplified, the device investment is lowered, the device operation difficulty and maintenance cost are lowered, and environmental pollution caused by exhaust emission is avoided.

Description

technical field [0001] The invention relates to a system for drying plants and extracting essential oils and pure dew, in particular to a system for drying plants and extracting essential oils and pure dew based on air energy. Background technique [0002] Such as figure 1 As shown, the traditional plant drying equipment is to place the plants 24 in the heating tank 1 made of metal, and the heating device 2 heats the heating tank 1 through the steam pipeline 22, so that the plants in the heating tank 1 are dried. An exhaust fan 23 is arranged on the top of the heating tank 1 to discharge moisture. The heating equipment 2 generally adopts boiler or electric heating equipment. This kind of equipment consumes a lot of energy, and the exhaust gas of the boiler pollutes the environment. Essential oils and pure dew products separated from plant fragrance materials cannot be collected. [0003] Such as figure 2 As shown, the traditional extracting equipment of plant essential...

AI Technical Summary

Problems solved by technology

[0004] In this method, the temperature exceeds 100°C due to the vaporization of water, and the aroma raw materials will react at high temperature. Usually, the aroma of essential oils and hydrosols and the aroma of the plant itself are quite different, which reduces the quality of the product.

In addition, because the heating equipment 2 generally adopts boilers or electric heating equipment, the equipment system is complicated, and the boilers, water towers and other equipment occupy a large area, consume high energy consumption, and the equipment manufacturing cost is also high, and the exhaust gas discharge pollutes the environment

Electric heating equipment also has the problem of high energy consumption

In addition, after the extraction of essential oils and hydrosols, the remaining plant fragrance materials such as fresh flowers cannot be reused, so they have to be discarded, and the utilization rate of fragrance materials is extremely low

[0005] Traditional drying equipment and essential oil and pure dew extraction equipment have single functions. The former can only simply dry plants, giving up the value of essential oils contained in plant aroma raw materials; the latter can only simply extract essential oils and pure dew in plant aroma raw materials. The value of flavonoids and polysaccharides contained in plant aroma raw materials is ignored

In addition, traditional equipment has low integration, complex equipment structure, high production requirements, large investment in manufacturing equipment, high production energy consumption, complex operation and maintenance, and environmental pollution by exhaust gas.
