Perfume drying device and essential oil recycling method

Abstract

The invention provides a perfume drying device which comprises a drying oven, a heat pump module, a heat exchanger, a fan and a gas circulating pipeline. The heat pump module consists of a coagulator, an evaporator, a compression pump and a refrigerant circulating pipeline, the refrigerant circulating pipeline is connected with the coagulator, the compression pump and the evaporator, and a refrigerant is compressed by the compression pump and then coagulated into a liquid state by virtue of the coagulator, and absorbs heat in the evaporator to be converted into a gas state. The heat exchangeris a gas-gas heat exchange device and is connected with the drying oven, the fan is connected between the drying oven and the heat exchanger so as to drive air to flow out of the coagulator by means of the gas circulating pipeline and flow back to the coagulator after passing through the drying oven, the heat exchanger, the evaporator and the heat exchange pipe. The invention further provides an essential oil recycling method using the drying device. Hot gas discharged from the drying oven exchanges heat with the heat exchanger through the evaporator so as to extract essential oil contained in the hot gas, the air temperature is improved by the coagulator so as to circularly dry the perfume, thus further achieving the energy-saving effect.

Description

technical field [0001] The invention relates to a deep processing technology of spices, in particular to a drying device in the deep processing technology of spices and an essential oil recovery method using the drying device. Background technique [0002] Spices include spices and aromatics. Spices are indispensable and important auxiliary materials in the food industry and catering industry. Among them, powdered spices are the most commonly used; and spices have a wider range of applications. In addition to the food industry, It can also be used in cosmetic industry. For traditional rough processing, during the processing of spices, whether hammer milling, roller milling, or disc milling, heat will be generated during the milling process, which will lead to volatilization, oxidation and even deterioration of the active ingredients in the raw materials. In addition, there are irreparable quality defects in powdered fragrances, such as unstable aroma intensity and aroma qua...

Problems solved by technology

[0004] However, although the drying method of the raw materials of the traditional spices can effectively remove the moisture in the raw materials of the spices, the essential oil components of the taste in the raw materials of the spices are also lost in large quantities, so that in the follow-up The volatile essential oils extracted from spices (such as pepper essential oil, ginger essential oil, garlic essential oil, rose essential oil, etc.) have limited essential oils

In addition, in the drying process of the raw materials of spices, a large amount of air needs to be heated, which will also cause a large amount of energy consumption
