Soxhlet Extraction Machines:
Soxhlet extractor is an automatic extraction method. It cycles the solvent through the same process after the first extraction. The herbal extract device heats the solvent until it boils. The vapor transfers into the extraction chamber. The herbal material sits in the chamber and leaches compounds from itself. The solvent containing the new compounds returns to the boiler chamber through a condensate tube. The process continues to repeat. The machine can extract various kinds of bioactive compounds from plants. It is suitable for solid-liquid extraction, likepolyphenols from apples peels.
Supercritical Fluid Extraction (SFE) Machines:
SFE machine uses supercritical fluids as extraction solvents to obtain natural plant extracts. It uses temperature and pressure to attain supercritical status for the solvent, usually CO2. In that status, the CO2 has liquid-like solubility and gas-like diffusivity, allowing it to penetrate material at a microscopic level. It extracts herbal material with great yield quickly. SFE offers selective extraction. It can be tuned to target precise active ingredients by adjusting temperature and pressure.Examples of extracts from SFE are essential oils and caffeine from herbal tea.
Semi-continuous Extraction Machines:
The semi-continuous extraction machine has batch or flow processing methods. In it, 2 to 5 extraction vessels perform simultaneously. The extracted material moves on without delay. So, the vessel number and continuous feeding raise output. Different extract solvents work for various herbs. The extraction temperature and pressure may also vary for specific active compounds.
A few typical specifications for herbal extraction machines are their capacity, the number of cycles they can operate in a day, the size of the machine, and the temperature control range, among others.
The capacity of an industrial herbal extractor machine can range from 5 to 125 kg. They are designed to carry out large-scale production in a continuous or batch mode. The daily yield of these machines can be anywhere from 300 to 3,000 liters, depending on the model and the type of extraction it carries out.
Industrial herbal machines for extraction are around the size of a room. Their dimensions can vary from 5000 x 2000mm to 10000 x 5000mm. The smaller ones used for more simple extractions and separating mixtures are about the size of a cabinet with dimensions of 800 x 600 mm. All machines, big and small, are made with stainless steel material that is corrosion resistant and is easy to clean.
Temperature control is an important feature of these machines because the extraction process depends on the temperature at which different active ingredients in the herbal extract react. These machines have the capability to work under high and low temperatures, sometimes up to 400 degrees Celsius and in vacuum conditions of 0.09 mmHg or even lower.
Maintenance and cleaning of the herbal extract machine is an important procedure. It not only helps to keep the machine working well for a long time but also helps to produce extracts of herbal medicine with maximum potency. The steps for cleaning are usually highlighted in the instruction manual provided by the manufacturer.
Essentially, a cleaning solution is prepared either through a CIP system or by manually preparing it. This is run through the equipment to clean it thoroughly from the inside and outside. Then after pouring it out, the machine is run through water to flush out any remaining cleaning liquid. Chemicals that are used to protect the blades and other parts from rust should be used before putting the machine in storage for a long time. Regular checks and running of the herbal extract machines without any material in them is also a good way to maintain their overall health.
Pharmaceutical industry:
In the pharmaceutical industry, herbal extract machines are vital for developing herbal-based medications. They aid in extracting active compounds from medicinal herbs that have healing properties, which are then used to formulate herbal remedies or supplements. Such products target consumers who seek natural alternatives to conventional medications for various ailments and health concerns.
Food and beverage industry:
In the food and beverage industry, herbal extract machines play a significant role in producing herbal teas and functional beverages. These extracts are used to flavor and enrich the nutritional content of beverages like energy drinks and protein shakes, giving them a competitive edge in the market.
Cosmetic industry:
Herbal extract machines find applications in the cosmetic industry for extracting bioactive compounds from botanical ingredients. These extracts are incorporated into skincare, haircare, and body care products for their nourishing, anti-aging, moisturizing, and antioxidant properties. Consumers are becoming more aware of what they put on their skin and hair and are therefore looking for products that contain natural ingredients. This is the perfect application for herbal extract machines.
Dietary supplement industry:
Herbal extract machines are widely used in the dietary supplement industry to extract active compounds from herbs such as ginseng, green tea, curcuma, etc. The extracted herbs are then processed into capsules, tablets, powders, or tinctures for nutrition and health. Consumers are increasingly seeking dietary supplements to support their immune systems, energy levels, digestion, and overall well-being.
Research and development:
Herbal extract machines are essential in research and development laboratories for studying the chemical composition of herbs. This enables scientists to investigate and understand the properties of various herbs and their potential applications. Such studies can lead to the discovery of new herbal extracts with unique health benefits and pave the way for innovative product development.
Chemical-free extraction:
It is vital to choose an herbal extraction technique that does not use synthetic chemicals. Methods like supercritical CO2 extraction, steam distillation, or cold pressing use no artificial solvents, making the extracts safe for consumers.
Reliable suppliers:
Consumers expect high-quality herbal extracts, so it's important to research potential extraction partners carefully. Select a supplier who has the right experience and the necessary certifications, such as GMP, ISO, or NSF, to ensure their quality control systems meet international standards.
Sustainable sourcing:
More and more customers want to know where their products come from and how they were made. Consider partnering with extractors who are transparent about their sourcing practices. Choose a supplier who uses sustainably cultivated plants and ethical harvesting methods to support environmentally responsible herbal extraction.
Extraction method:
A variety of extraction techniques are available, each suited to different types of herbs and desired extracts. Factors like yield, potency, cost, and efficiency vary by method. Common extractions include steam distillation for essential oils, solvent extraction with alcohol for flavorful extracts, supercritical CO2 extraction for phytochemicals, and cold pressing for certain oils. Consider the extract's intended use and choose an extraction technique that provides the functional ingredient needed for the final product.
