Embodiment 1

[0037] Objective: To establish a technique for preparing an extract from fresh orange peel, which is a light orange-yellow clear liquid with a unique aroma of fresh orange.

[0038] Main material: fresh orange peel cut into chunks.

[0039] Main equipment: differential pressure extractor with condensing device, vacuum pump.

[0040] Preparation process:

[0041] 1. Cut the orange peel into pieces: take fresh orange peel, cut it into pieces of about 1×1cm, and put it into the differential pressure extractor;

[0042] 2. Confirmation of condensed water temperature: Confirm that the condensed water temperature is below 0°C.

[0043] 3. Vacuuming: within 1 minute, use the vacuum station to evacuate to form a vacuum in the differential pressure extractor. The vacuum degree is controlled at 50Pa ~ 100Pa, keep it for 3 minutes, and spray an appropriate amount of purified water at 0°C ~ 4°C.

[0044] 4. Vacuum reduction: Slowly introduce purified compressed air to gradually increas...

Abstract

The present invention relates to biomass extracting technology, and is especially low temperature pressure difference extracting technology. Pressure variation technology of vacuum-normal pressure or vacuum-pressurizing is used in speed the leaching of intracellular solution during extraction. The technological process includes circulation of vacuum pumping, spraying solvent, reducing vacuum, pressurizing and decompressing in the required time number. The technology of the present invention is suitable for extracting effective components from animal, plant and microbe material for production of medicine, health article and food.

Description

technical field [0001] The invention relates to a biological substance extraction technology, in particular to a low-temperature differential pressure extraction technology. Background technique [0002] With the gradual warming up of the human tendency to "return to nature", people's demand for active ingredients or effective parts contained in biological organisms such as animals, plants, and microorganisms that have a positive effect on human health care continues to grow. [0003] Biological organisms are composed of complex chemical components, but the effective active ingredients contained are often very small. For example, the traditional Chinese medicine Corydalis tuber contains only about 1% of the effective part of blood circulation and pain relief - alkaloid content. [0004] The natural resources of biological organisms are very rich. In recent years, with the development of molecular biotechnology, the types of genetically modified organisms have become increas...
