Plant extracts are mainly used in food, health care products and other industries related to life and health, thus the factors affect the quality of plant extracts, such as impurities, moisture and microorganisms of. Plant extraction equipment will become an important guarantee for the quality of plant extracts. Among various types of equipment, the disc centrifuge is widely used in pharmaceutical industry. Centrifuge has vantage point of keeping the active ingredients during separation process, meanwhile, it shortens the sedimentation time, improves the clarity of the product and increasing the output.The centrifuge equipment fully meet the requirements of GMP certification.

After reaching the standard of liquid fermentation, the Lactobacillus can be concentrated or collected by high speed tubular separator. The following processes are determined according to the tolerance of the bacteria to the temperature. They are spray drying or freeze drying methods to obtain dry powder. Critical control point is to ensure activity of collected bacteria, Crown Machinery’s high speed tubular separator is one of the best option for concentrate Lactobacillus efficiency.

There is an increasing interest in large‐scale production of tailored chemicals from renewable resources. Such production typically involves a fermentation step where microorganisms produce the chemical of interest. The extraction of the chemical from the fermentation broth usually necessitates the removal of the microorganisms in a prior process step. In biomedical applications, Crown Machinery’s biomaterial series disc stack centrifuge of hermetic design are known to be well‐suited for this removal step. The agglomeration can be achieved by the addition of coagulants or flocculants to the fermentation broth before the separation. For this technique to be successful the agglomerates cannot break apart due to, e.g., shear forces in the inlet of the centrifuge. If single organisms break loose from the agglomerates, they are likely to pass through unseparated.

Cannabis extraction apply traditional solvent extraction technology, which is commonly used in traditional Chinese medicine extraction, it has the advantages of less organic solvent, high recovery rate, simple operation. Ethanol is generally used as the extractant, can not only dissolve some water-soluble components, but also some components dissolved by non-polar solvent. Moreover, ethanol extraction can reduce the extraction of impurities such as mucus, starch, protein and so on. The CBD extraction centrifuge equipment designed by crown machinery is as herbal extraction system, with ultra-low temperature designation, realize low-temperature extraction and concentration at the same time. It has the characteristics of high extraction yield and stable nature of the extracted effective components. The equipment adopts automatic drainer design, which can realize automatic extraction and reflux. Moreover, ethanol can be recycled to solve the problems of cost and pollution. Please call and consult for more details.

All parts of waste water treatment series decanter centrifuge are prepared to deliver to customer in US, Crown machinery’s decanter centrifuge series is a good replacement of belt filter in condition of sludge treatment and disposal process of ETP (Effluent Treatment Plant). Below are some advantages of using a decanter centrifuge to replace the belt filter : The horizontal screw decanter centrifuge can run continuously for 24 hours. The horizontal screw decanter centrifuge operate under the principle of centrifugal sedimentation, separate the solid and liquid. As the filter screen is installed, sludge will not cause the blockage. Belt filter use filter belt to separate the solid and liquid, in order to prevent the filter belt from clogging, require continuously washing by high-pressure water. When the feeding water’s concentration changes during the dehydration process via decanter centrifuge, the speed difference and torque of bowl and screw will automatically be tracked and adjusted, not require of a specific operator. When using belt filter in same condition, belt speed, belt tension, dosing amount and flushing water pressure all need to be manually adjusted, thus a dedicated operator is necessary. The centrifuge occupies small space, simple installation and commissioning, the accessory equipment only including the dosing system and feeding conveyor. The belt filter occupies a large area, and the supporting equipment, in addition to dosing system and feeding conveyor, also needs flush pump, air compressor, sludge conditioner, etc. The high-pressure cleaning water mist and odor accrued during the operation.
