Super Critical CO2 Extraction Machine for Hemp Tea Leaf Herb Pea Protein

Working principle of supercritical extraction equipment: The principle of the separation process is to use the relationship between the solubility of supercritical fluid and its density, that is, the influence of pressure and temperature on the solubility of supercritical fluid. In the supercritical state, the supercritical fluid is brought into contact with the substance to be separated, so that the components of the polarity, the boiling point, and the molecular weight are selectively extracted in order.

Abstract:

As a green technology, supercritical CO2 extraction has widely applied in extraction of natural materials. The annual production capacity ranges from hundreds of tons to tens of thousands of. However, the separation efficiency of supercritical CO2 extraction is very low, especially for mixtures with small different properties of composition, because it is only one stage separation. Continuous countercurrent supercritical CO2 extraction (CC--SCE) is a multistage separation process, which enables isolation and purification of components with very similar properties. But, CC-SCE is far behind the development of supercritical CO2 extraction technology. This paper introduced CC-SCE’s process and its application in concentrating paprika pigment in terms of industrial scale. The prospect of CC-SCE was also made in other applications, like purification of ginger oil, tocopherol and citrus oil etc.Key words: supercritical CO2; countercurrent extraction; natural material.

Description

Continuous countercurrent supercritical CO2 extraction (CC-SCE) is an effective way to achieve continuous operation of liquid materials. The countercurrent extraction process in the tower equipment is a differential contact extraction process, and the CO2 phase fills the entire column. Continuous phase, the raw materials are distributed in the continuous phase in the form of droplets, which is a dispersed phase. The CO2 phase is added from the bottom of the tower and led out from the top of the tower; the raw materials enter from the top of the tower or the side of the tower, and the raffinate is collected from the bottom of the tower. At the same time, in the presence of a temperature gradient, the solute can form an internal reflux, like distillation. After multi-stage equilibrium of dissolution-precipitation-dissolution, the solute comes out of the column with CO2 into the separator and is collected separately. Feeding and discharging are realized by high-pressure pump and valve automatic control. Due to the continuous operation of the extraction process, the equipment processing capacity is greatly increased, the process energy and gas consumption are reduced, and the production cost is reduced. In addition, the materials and supercritical CO2 pass through the packing in the tower. Or the plate is used for mass transfer, and the number of theoretical plates is high, which can achieve effective separation and purification of the mixed solution with small separation factor and difficult to separate.

Shi Bingjie used methylated soybean oil deodorized distillate as raw material, studied the process route of CC-SCE concentration of natural vitamin E, and discussed the effects of temperature, pressure, filler height and other factors on the extraction process. When the raw material feed rate is 0.02 kg / h, the extraction pressure is 20 MPa, the extraction temperature gradient is 40-45-50-60-70 ℃, and the gas-liquid ratio is 80 kg / kg under the experimental conditions, the mass fraction of vitamin E And the yield reached 24.3% and 81.5%, respectively. When using double-column continuous countercurrent operation, the natural vitamin E mass fraction increased to about 54%, and the yield reached 95%.

  The color price of raw material for capsicum pigment is 24000. Under the CO2 flow rate of 30000M3 / h M2 and the pressure is 36MPa, the color value of capsicum pigment increases by more than 6 times, up to 150,000. Compared with the results of supercritical CO2 extraction, under the same volume of autoclave and processing capacity, the countercurrent treatment time is only half of the traditional processing time, and the color value concentration multiple of the countercurrent extraction product is much larger than that of the first-stage extraction. It can be seen that the countercurrent extraction process greatly improves the production efficiency of the equipment, reduces the production cost, and has high practical value.

Supercritical CO2 fluid technology as a solvent has the advantages of no pollution, no solvent residue, no damage to the effective ingredients in bitter almond, targeted extraction, making the bitter almond saponins safer, more reliable and more valuable. Therefore, it can reduce costs, save time and bring greater economic benefits for enterprises.

Supercritical fluid extraction technology and its application in food industry

Summary:

Traditional extraction methods of natural products in the food industry generally have many shortcomings such as the heavy use of organic solvents in the production process, pollution of the environment, long processing time, complicated operating steps, low extraction rate, and low purity of the extract.Therefore, green and efficient supercritical Fluid extraction, especially supercritical CO2 extraction technology, has received widespread attention and application in the field of natural product extraction in recent years.

Supercritical fluid extraction technology has attracted extensive attention as a new and green extraction process. Compared with traditional extraction processes, it has better extraction and separation capabilities and does not cause pollution to the environment.

We will to mainly introduces the basic principle of supercritical fluid extraction, the important variables affecting the extraction process and how to optimize it. Focuses on the application of supercritical fluid extraction technology in the food industry, such as extracting active ingredients from plants, animals and agricultural by-products.

Solve the problems of organic solvent residues in the traditional extraction process, provide new methods for the preparation and extraction of samples in the test, provide new technical means for small and medium-sized industrial production, and provide theoretical basis and technical support for the development of new products.
