Jiangsu Flash Dryer is a new type of continuous drying equipment integrating drying, crushing and sieving. It is especially suitable for drying cake cake, paste and muddy materials. The drying time of the wet material in the drying tower is only 5-8 seconds, and the moisture instantaneously evaporates. The quality of the dried product has a great relationship with the drying temperature, wind speed, air volume and breaking speed. The hot air enters the annulus at the bottom of the drying chamber in a tangential direction from the inlet pipe and spirals upward. At the same time, the material is quantitatively added to the tower by the feeder and is fully exchanged with the hot air. The larger and damp material is in the agitator. Under the action, it is mechanically broken, and the material with low moisture content and small particle size rises together with the rotating airflow, and is sent to the separator for gas-solid separation. The finished product collects the package, and the exhaust gas is emptied after being treated by the dust removing device.
Equipment advantages
1. The indoor air velocity in the drying chamber is high, and the material residence time is short, which effectively prevents the material from sticking to the wall and the heat sensitive material from deteriorating, and can be dried into a uniform powder product at one time, eliminating the steps of crushing and sieving.
2. The drying chamber is equipped with a grading ring and a swirling sheet, and the material fineness and final water content are adjustable. The special air distribution device reduces the resistance of the equipment and effectively improves the uniformity of the material.
3. The special cooling device and air pressure sealing device are installed at the bottom of the dryer to avoid the deterioration of the material in the high temperature zone at the bottom.
4. It can effectively control the final moisture and fineness. Through the adjustment of feeding, hot air temperature and classifier, the moisture content and fineness of the product are guaranteed to be uniform.
Virus Specimen Collection Tube
Inspection principle:
It can perform protein denaturation on fresh clinical virus samples to inactivate the virus, prevent secondary transmission of infection, and ensure the safety of transportation and testing personnel.
♣.Structural composition: Combination of cotton swab and transport medium (VTM).
♣. Product requirements:
The product should be airtight, avoid high temperature, avoid direct sunlight storage. It should be used in a clean, hygienic, pollution-free, and temperature-friendly environment.
♣, Storage conditions and validity period:
â‘ , the product should be stored in a clean, dry and ventilated environment,
②, the temperature is 5℃-35℃;
â‘¢, relative humidity <85%RH;
â‘£, product shelf life: 12 months.
♣. How to use
â‘ Before sampling, mark relevant information on the label of the sampling tube.
â‘¡. Sampling with the corresponding cotton swabs.
â‘¢ After the collection is completed, quickly put the cotton swab into the collection tube, break the part higher than the sampling tube, and tighten the tube cover.
â‘£. For the specific sampling method, please refer to the following:
a) Nasal swab Gently insert the sampling head into the nasal cavity, stop for a while and then slowly rotate to exit, immerse the collected specimen in the Xiangxiang solution, break the excess part and discard it, and tighten the sampling tube cover.
b) Pharyngeal swab: Wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with the sampling head, immerse the collected specimen in the sampling solution, break off the excess part and discard it, and tighten the cap of the sampling tube.
c), Mycoplasma Chlamydia, Ureaplasma specimen collection
Male: Insert the sampling head into the urethra about 2cm and rotate, stay for a while and then exit, and immerse the collected specimen in the sampling solution.
Female: Wipe the mucus of the cervical orifice, insert the sampling tip into the cervical canal for 1-2 cm for sampling, immerse the collected specimen in the sampling solution, break off the excess part and discard it, and tighten the cap of the sampling tube.
♣. Precautions
1. After the virus is collected, the disposable sampling swab should be completely inserted into the preservation solution, so that the virus can be retained to the greatest extent possible.
â‘¡ The collected specimens must be sent for inspection in time.
â‘¢. It is forbidden to use products with damaged packaging and expired validity period to prevent pollution.
This single-use Virus Sampling Tube is used for in vitro diagnosis. It cannot be used for human or animal oral or external use. If swallowed, it may cause serious events; it is irritating to eyes and skin. If it is not splashed into the eyes, rinse with water.
