Description

Technical Field

[0001] The present application relates to the technical field of aroma extraction equipment, and in particular to a collection mechanism for jasmine aroma. Background Art

[0002] The air circulation method is generally used to collect the scent of jasmine flowers. That is, the principle of air circulation is used to place the plant parts containing essential oils in a fragrance collection box, and the air is blown into the fragrance collection box through an induced draft fan so that the air contacts the plants and the essential oils evaporate. The air with essential oils is then transported to the condensation box in the ice machine through a pipeline, and the essential oils and water are separated through a condensation tube and a condensation plate to obtain essential oils and fragrance. This method can extract high-quality essential oils and fragrance, and the equipment is simple, easy to operate, and energy-saving and environmentally friendly.

[0003] The existing equipment for extracting floral fragrance by air circulation method mainly includes the following parts:

[0004] Aroma box: This is a container for placing plant parts containing essential oils (such as petals, leaves, etc.). It has a bamboo sieve frame inside, which can be used to place different plants in layers to increase the contact area and improve the extraction efficiency. The top of the aroma box is connected to the ice machine through a pipe, and the bottom is connected to the ice machine through a return pipe, forming an air circulation system.

[0005] Ice machine: This is a device used to cool and separate essential oils. The inner wall is equipped with an insulation layer and a condenser box inside. The condenser box is equipped with a condenser tube and a condenser plate. One end of the condenser tube is connected to the pipe and the other end is connected to the condenser plate. It is used to cool the air with essential oils and separate the essential oils and water. The essential oils flow into the storage tank. There are exhaust holes on the top of the condenser tube and the condenser box to exhaust excess air and water vapor.

[0006] Induced draft fan: This is a device used to generate and maintain airflow circulation. It is installed on the duct and drives the fan through electricity to draw air from the aroma box and send it to the ice machine. The induced draft fan can adjust the wind speed and air volume to suit different plants and extraction conditions.

[0007] Regarding the above-mentioned related technologies, the air carries the aroma naturally emitted by the plants. In this process, the amount of essential oil that can be carried by a unit of air is relatively small, and the aroma collection efficiency is low. Summary of the invention
