These unparalleled advantages make extraction efficiency greatly improved. The promotion of this instrument will make the extraction technology of Chinese herbal medicine chemical composition develop rapidly, greatly accelerate the modernization process of Chinese medicine, fill the gaps in this field at home and abroad, and lead the research and production of traditional Chinese medicine and natural products from traditional to modernization and internationalization.

Six, the flash extractor uses tips

Flash extractor is a new type of extraction equipment, widely used in the extraction of Chinese herbal roots, stems, leaves, flowers, fruits, seeds, etc., suitable for a variety of solvents (except for ether and other toxic solvents such as ether), can be a single Chinese medicine Extraction, can also be multi-flavored Chinese herbal compound extraction. The extractor tips are described below:

(1) Requirements for the size of the pieces:

  The flash extractor is extracted by the original structure of the tissue. During operation, the inner knife rotates at high speed under the drive of a high-speed motor, generating a strong vacuum negative pressure. The traditional Chinese medicine piece enters the outer knife cavity under the action of negative pressure, and the inner and outer blades The pieces are cut into 40-60 mesh granules, which are then pulled out of the cavity by the outer knife window to complete an extraction process. Therefore, when using the flash extractor, whether it is single-flavor extraction or compound extraction, the medicinal material pieces must first be treated so that the diameter of the pieces is smaller than the diameter of the outer knife cavity, so that the pieces can enter the extraction system. The outer cavity of JHBE-50T flash extractor has a diameter of 2.8cm, so the diameter of the piece should not exceed 2.8cm, and one third of the inner diameter of the cutter head is suitable. When extracting softer herbs such as flowers and leaves, the diameter is not too large to be able to enter the outer knife cavity.

(2) Requirements for solvents:

The selection of a suitable solvent is one of the key factors for the extraction yield; the solvent in which the active ingredient is most soluble is certain, so it is required to select a suitable solvent during the extraction process. Xi'an Jinnan Biological Technology Co., Ltd.

When the flash extractor is working, it is required that the piece must be able to "swim" in the solvent in order to achieve the desired extraction effect. The standard container of JHBE-50T type flash extractor is 4 liters, and the amount of solvent added is not more than 60% of the volume. The amount of medicinal material is convenient for agitation.

(3) Start the high speed motor:

The first 5 seconds of the blade's start is the stage where the motor load is at its maximum. It needs to have enough power to rotate the inner knife and shred the larger pieces. Therefore, when starting the machine, it is required to quickly adjust the speed control knob to 4 to 5 to prevent the blade from being stuck. If the cutter head is stuck after the speed adjustment, the gear position should be quickly adjusted to the zero position at this time, the cutter head is raised, and the material stuck in the inside is lifted and restarted. Choose the appropriate speed based on the texture of the extracted herbs, not the higher the better.

(4) Adding herbs:

When the motor starts smoothly and there are no larger particles in the container, the medicine can be gradually added to the extraction tank. Add a small amount multiple times and add evenly. The maximum extraction amount of JHBE-50T is 500g.

(5) How to save solvent:

One of the advantages of a flash extractor is that it saves solvent over conventional methods, but needs to be prepared for extraction. Prepare 4 configuration containers in advance (or replace them with similarly sized containers), add solvent and medicinal materials for extraction according to the above requirements. After the first container is completed, place one side first, continue the extraction of the second container, wait for the third. After the extraction of the containers is completed, the supernatants in the first and second containers are poured into the fourth container, and an appropriate amount of the medicine is added to continue. By taking turns in this order, the extraction work can be completed with a small amount of solvent.

Considering the extraction yield problem, it is recommended that the filtered residue be soaked in fresh solvent for about 10 minutes and then extracted a second time with a flash extractor. (6) Other magical effects of the flash extractor:

Flash extractor is a kind of innovative high-tech developed by our company experts in the long-term work practice, based on the actual needs and the desired ideal effect, fully absorbing the latest technological achievements at home and abroad, independent research and development, continuous improvement and perfection. equipment.

The stirring, mixing, crushing and shearing effects produced by the machine can be widely used in food, chemical, cosmetics, biotechnology and other fields. .

Enclosure: Detailed description of the flash extractor

The flash extractor is a high-tech equipment for the extraction of Chinese herbal medicine. The equipment is based on the principle of tissue disruption. According to the purpose of “extraction” and the characteristics of the process and technical requirements, it fully absorbs the latest technology at home and abroad, scientific design and elaborate production. It not only achieves fast, efficient, full and complete extraction requirements, but also does not require heating, saves energy, and effectively protects the heat-sensitive components of the extracted substances; the original hours of extraction work can be completed in just a few minutes, and the work efficiency is high. It is easy to operate and has significant advantages compared with traditional extraction methods. It is a powerful tool for Chinese medicine researchers to extract.

Structural features:

The flash extractor consists of a high-speed motor, a crushing extraction cutter head and a control system. The structure design is simple, compact, reasonable and easy to operate. The main part of the work is the crushing and extracting cutter head. The cutter head is composed of an inner cutter and an outer cutter. When the inner cutter is driven by the high-speed motor, the speed is adjusted by the control system and the high speed is rotated in the outer cutter cavity, so that the whole system is in the middle. In a high-speed dynamic environment, not only strong shearing action is generated between the inner and outer knives, but also a strong negative pressure is generated in the outer knife cavity. Under this negative pressure, molecular penetration occurs inside and outside the outer knife cavity, that is, through The broken and fully exposed material molecules (extracted components) are surrounded by solvent molecules under the action of various external forces such as negative pressure, shear, high-speed collision, dissociation, dissolution, substitution, and detachment, and then quickly enter the solvent to instantly dissolve. The concentration balance quickly completes the extraction process in tens of seconds.

After a large number of experiments, the extraction efficiency of the equipment is better than traditional methods such as boiling, refluxing and seepage. More than ten research papers have been published in domestic professional magazines. The equipment has passed the high-tech achievements of Henan Science and Technology Department and obtained the patent certificate.

Organic Erythritol

Organic erythritol is produced through multiple hydrolysis and fermentation of corn starch. It is a natural sweetener. Erythritol is usually white particles or powder.

The sweetness of erythritol is only 60%-70% of that of sucrose. It has a refreshing taste, pure taste, and no bitterness. It can be used in combination with high-power sweeteners to suppress the bad flavor of high-power sweeteners.

Erythritol is different from traditional sugar. It is very stable to acid and heat and has high acid and alkali resistance. It will not decompose and change below 200 degrees, and will not change color due to the Maillard reaction. Erythritol has an endothermic effect when dissolved in water, and the heat of dissolution is only 97.4KJ/KG, which is higher than glucose and sorbitol, and has a cooling sensation when eaten.

It does not participate in sugar metabolism and blood sugar changes, so it is suitable for diabetics. It does not cause fermentation in the colon and can avoid gastrointestinal discomfort. It does not cause tooth decay.

Organic erythritol is the most reliable choice in many fields, such as beverages, candies, baked goods, dietary sweeteners, and functional foods. We provide pure organic erythritol and a mixture of erythritol and any other natural sweeteners!

Our organic corn farm is located in Heilongjiang Province, where the soil is fertile, especially suitable for growing corn. Our organic erythritol is produced in strict accordance with the organic standards of the European Union and the United States Department of Agriculture.
