Problems solved by technology

However, the domestic production technology of Zanthoxylum bungeanum is extracted with organic solvents, the product yield is low, the loss of volatile oil is large, and there are solvent residues, and the food safety is poor. At the same time, most organic solvents are volatile, flammable and explosive.

Embodiment Construction

[0007] The process in the embodiment includes: crushing the dried prickly ash pericarp (moisture is controlled below 14%) with a pulverizer with good airtightness, and the particle size is 60 mesh. Put the Zanthoxylum bungeanum powder into a special extraction tank, lift the tank into the extraction kettle with a crane, then seal the extraction kettle, raise the temperature of the extraction kettle to 30-55°C, and then turn on the booster pump to pump in the carbon dioxide fluid. Raise the extraction pressure of the extraction kettle by 15-35MPa, slowly open the reflux valve, keep the pressure of the extraction kettle stable at 20-35Pa, and maintain the fluid flow rate at 8-25kg / h. The carbon dioxide fluid released from the extraction tank enters the separation tank, so that the soluble components of pepper dissolved in the carbon dioxide fluid are separated from the carbon dioxide in the separation tank, and the separated carbon dioxide fluid is returned to the carbon dioxide ...

Abstract

The invention provides the production technique for extracting pepper essence by supercritical carbon dioxide process which consists of, loading the dried pricklyash peel into air tight comminuting machine for disintegration, loading into abstraction bucket for abstraction with carbon dioxide liquid, lifting the abstraction pressure to 15-35 MPa, flowing the carbon dioxide liquid into the segregation still, thus disintegrating refined pricklyash peel with carbon dioxide.

Description

technical field [0001] The invention relates to a production process of condiments, in particular to a production process for extracting prickly ash essence by supercritical carbon dioxide method Background technique [0002] Pepper (Zanthoxylum L.) belongs to Rutaceae, and its peel is known as one of the "eight condiments", and is a commonly used cooking seasoning and traditional Chinese medicine ingredient in the family. Zanthoxylum bungeanum has a long history of cultivation in my country and is widely planted. Zanthoxylum bungeanum is an important spice and medicinal economic crop. In the process of implementing the agricultural industrial structure adjustment and returning farmland to forest policy in my country, its planting area and output have increased rapidly. By 2001, the national Zanthoxylum bungeanum planting area had exceeded 60,000 Hectares, the output of pepper peels is nearly 100,000 tons, and it has formed nationally famous pepper planting bases such as Han...
