Application : This series of extraction unit is designed for scientific researching and testing.
It is not applicable to commercial production. For the ones who want to start a business, we recommend you our Industrial Extraction Equipment.

Key Technical Equipment of Extraction Unit

We provide a wide capacity range for different needs. It is classified according to the volume of extraction pot. Below is the main equipment consists of a pilot solvent extracting line.

Oil, Oleoresin, Extractum and Defatted Protein

Oil & oleoresin, extractum and defatted protein are the products you can get directly fromt he extraction machine. First of all, let's see what's the difference between oil and extractum products. For oil seeds and crops, oil products can be extracted directly by the small unit. For flower, herbal and spice, the product is pasty extractum or Oleoresin. If you want to get final essential oil, dewaxing device is needed additionaly. For pigment extraction, you can only get pasty extractum, after-treatment equipment is needed for final purification.

Extracting Process of Pilot Unit

The pilot solvent extraction unit is the best coice for essential oil extraction testing. It adopts low temperature subcritical biological extraction technology to process raw materials. The main solvents in application are liquid propane, butane, dimethyl ether, R134a and liquid ammonia. Under room temperature (low temperature) and certain pressure, it utilizes liquefied sub-critical solvents to process raw materials through countercurrent extraction, further obtains the extract liquor (liquid phrase) and raffinate (solid phrase). The solvents in extract liquor will be separated with target composition through vaporization in the process of distilling (vaporizing), which brings the final products. Meanwhile, the solvents absorbed in the raffinate, also refers to the extracted material, will be distilled out, and the raffinate through distilling will be become another product. It's also worth mentioning that vaporized solvents can be liquefied for recycle uses. The whole process is going under room temperature, therefore, thermosensitive substance within raw material can be better protected.
Our pilot solvent extraction equipment is designed for small or small-scale natural substance extraction research, testing, and design. This is the ideal choice for laboratory qualitative testing. It can be used to extract high-quality plant oils, essential oils, animal oils, microalgae oils, natural pigments, plant proteins, plant spices, etc. Moreover, it is a popular essential oil extraction kit/device on the market. Target users: scientific researchers, researchers, schools, research institutes, laboratories, and other similar users.
Soybean protein powder is a high-quality plant protein. Soybean flour protein with equal nutritional value and good functional characteristics has been widely used in the food industry. Low temperature defatted soybean meal is the main raw material for extracting soybean protein powder. In industry, the soybean carrot extraction method. However, the high-temperature solvent removal and n-hexane solvent in this process have prompted people to seek alternatives to achieve better production.
New Technology for Processing Soybean Powder Protein
Subcritical solvent extraction is an emerging extraction and separation technology. The biggest advantage is the low-temperature extraction process. And the most suitable solvent can be selected as the target product based on different properties. Subcritical solvent extraction technology can also use co solvents. Therefore, it is of great practical significance to leverage the advantages of subcritical solvent extraction technology and promote the rapid development of the soybean protein industry.
Characteristics of soybean protein production technology
The production of soybean protein powder using subcritical solvent extraction technology has many outstanding characteristics.
The soybean meal processed using subcritical solvent extraction technology has a high content of protein and phospholipids, and is fully committed to the goal.
The soybean meal protein isolate processed using subcritical solvent extraction technology has high concentration, good emulsification and stability.
Proper use of co solvents in the production process can improve the quality, skin tone, and emulsifying properties of soybean protein.
The purity and recovery rate of protein extracted from soybean meal using subcritical solvent extraction technology are comparable to any other thermally modified soybean meal.
Product removal:
For oilseeds, oil and skim protein can be directly extracted through this equipment.
For natural pigments, you can obtain a paste like extract or oleoresin (requiring purification equipment for post-treatment).
For herbs, flowers, and spices, extracts or oleoresins can be obtained, and additional dewaxing devices are required to obtain the final essential oil.
Output: 5-150L per batch
