Extraction and concentration are two different processes. At the request of the client, Zhejiang Gemini engineers designed a continuous operation for extraction and concentration, which can achieve automatic control. At the same time, a corresponding filtration system is matched according to the material characteristics, and the residue can be extracted a second time through the transmission system, improving the extraction rate of effective substances. The extraction equipment can be linked with different types of concentration equipment, and depending on the material characteristics, single-effect, double-effect, or triple-effect concentrators can be selected. The equipment meets GMP standards and is widely applicable in various fields: *Pharmaceutical field* Natural food and health product field* Natural plant extraction and pigment extraction field.
The overview of continuous countercurrent extraction ensures continuous operation and dynamic countercurrent extraction, improving production efficiency, reducing solvent usage, lowering extraction temperatures, ensuring product quality, reducing energy consumption, ensuring the safety of the production process, and avoiding environmental pollution from herbal residues. It is a set of efficient, energy-saving, safe, and environmentally friendly equipment for the production and processing of natural products, widely used for extracting various natural products from herbal materials using various solvents, especially for the extraction using volatile organic solvents and for large-scale extraction of single herbal materials. The promotion and application of this equipment will greatly enhance the industrialization and modernization of traditional Chinese medicine and natural products.
The vacuum extraction and concentration unit developed by our company has the following characteristics: 1. The concentration heating area is large, with high thermal efficiency, short concentration time, not easy to scale, and easy to clean. The unit has an intermediate storage tank for the extract, which is stored in the tank at the bottom of the evaporator. The extraction tank can discharge residue and prepare for the next batch of extraction. During this period, the concentrator completes the concentration of the extract and prepares for the next batch of extraction; 2. The extraction yield is increased by more than 8%, with high effective components. The extraction and concentration are completed in the same closed equipment, resulting in minimal loss. Due to the use of low-temperature extraction, the quality of the extract after concentration is high, with pure color, aroma, and flavor; 3.
The TD-Z multifunctional conical extraction tank is suitable for the extraction processes of plants and animals in industries such as pharmaceuticals, biotechnology, beverages, food, and chemicals. It can perform operations like atmospheric pressure, pressurized extraction, decoction, temperature soaking, hot reflux, forced circulation, leaching, essential oil extraction, and organic solvent recovery. The dynamic extraction or multi-tank countercurrent extraction methods yield better results, with shorter time and higher active ingredient content. The tank is equipped with a CIP cleaning automatic rotating spray ball, thermometer, pressure gauge, explosion-proof viewing light, sight glass, and quick-opening feeding port, ensuring ease of operation and compliance with GMP standards. The inner tank body is made of imported 304 or 316L stainless steel with aluminum silicate insulation. The complete equipment set includes the extraction tank, foam remover, cold trap, cooler, oil-water separator, filter, cylinder, control console, and other accessories. The equipment occupies a smaller footprint, making it widely used in extraction workshops. The discharge door is equipped with bottom heating to ensure more complete extraction of the materials.
