Sieves are the most effective devices used for separating elements of different sizes by the means of perforated or meshed surface. One can use these sieves for separating fine material from coarse material. Based on how these sieves are used and what kind of particles are separated, sieves differ in application, size and shape.
Majority of the sieves that are been used are analytical sieves. These are widely used in different industrial processing units, laboratory analysis as well as kitchen industries.
Why Is Cleaning of Test Sieve Important?
Test Sieves used for laboratory or scientific experiments are the highly accurate tools developed and designed for scientific excellence and procedures.
Regular usage of these equipment for different researches and scientific experiments makes them vulnerable and prone to damage very easily.
It requires taking special care to avoid the sieve from any distortion or any damage since occurrence of any of these can alter the reliable laboratory results.
Careful cleaning of these test sieves is therefore important and should be an ongoing process to get accurate and most precise results in the lab.
How To Clean Test Sieves Properly for Higher Precision?
The primary reason why sieves are easily damaged is not because of their work or how they are utilized, but it is due to the rough cleaning process they have undergone. When the sieve is strongly tapped to clean the mesh of the gathered particles during a cleaning process, there is a strong potential of damaging a fine sieve working versatility.
So, to avoid damages occurring on the sieve it is important to clean it before and after the usage. Below is the basic procedure which can be utilized for cleaning your test sieves properly.
- Sieve cleaning brush is commonly used for cleaning your test sieve. You need to apply very light pressure while brushing the wire cloth of the sieve in circular motions.
- Then tap the frame of the sieve gently, with the handle of the brush so that the attached particles (to the fine mesh) gets dislodged.
- Now wash the sieve using warm soapy water. This will remove all the near-sized particles which are already lodged in the mesh.
- You may need to brush the underside of the sieve- placed in the water.
Although above process is good enough for regular cleaning of test sieves, ultrasonic sieve cleaning is often recommended, especially for sieves with finer mesh.
Important Things to Care For:
Clean you’re newly bought test sieve using a warm soapy water, before using it for test. This will remove any unwanted greasy material or oil, if present. Cleaning your test sieve, after conducting the tests, should be accompanied with caring tips so that you can enjoy the precise results every time.
You need to examine the finer sieves periodically so that you can detect any damaged openings or perimeter separations early. You can do this by examining the sieve against a white background or backlight. Magnifying glass can be used for viewing if required.
Below are few additional things which you should avoid completely while cleaning the test sieves.
- Do not use compressed air or power tools for cleaning or forcing out the embedded particles from the test sieve mesh.
- Do not use any acidic or chemically harsh solvents for cleaning as it can adversely affect the accuracy and precision of the sieve.
- Do not use bush for cleaning sieves which are finer than 45 um (#325). Ultrasonic sieve cleaner should be used for these sieves.
- Worn out or damaged openings in the sieves makes them in accurate. You should replace these types of test sieves rather than repairing them. Also do not use the sieve for testing if the mesh wire cloth is loose or carries any defects.
Well, when you have cleaned up your test sieve perfectly it is time to store them properly. Always store them in a place with clean dry conditions. If possible use a vertical rack which separates the different sieves within different compartments. This will not only prevent any damage but also keeps them well organized for easy access whenever required.
As such there are many different types of sieve cleaning brush and solutions available in the market. But using a professional ultrasonic cleaning device for sieve cleaning is often recommended and can do a magic for you.
Why Ultrasonic Cleaner for Sieve Cleaning Is Recommended?
Sieve cleaning is although a time consuming procedure, but if cleaned using ultrasonic sieve cleaner you can certainly get finer results in very less time.
Ultrasonic cleaning devices for fine mesh sieves offer best cleaning results to that compared to the human cleaning method and for this reason these are mostly recommended and used as compared to other methods.
These devices employ its powerful strategy for gently cleaning and removing the sample residues from the test sieves without getting any damage to the mesh material.
By cleaning the sieves through this procedure, one is ensured that there is no damage seen to the sieve. Additionally the fine mesh size is not affected at all when the ultrasonic cleaning method is employed for sieve cleaning.
Furthermore cleaning your sieve through ultrasonic cleaner will increase your sieving capacities up to ten times by enabling the particles to pass through the screen faster. Sieve on the finer meshes can obtain better results and it increases the overall screen life too.
Ultrasonic sieve cleaners such as Elma Compact Ultrasonic Test Sieve Cleaner are now available in the market and has made the sieve cleaning process much easier for industries and labs.
How Ultrasonic Sieve Cleaner Work?
The cleaning process of sieve through ultrasonic sieve cleaner is standardized and can be repeated as number of times which makes it cost effective as well as ideal for the defined laboratory applications.
The unclean sieve is first placed under an ultrasonic water bath that is filled with aqueous cleaning liquid (made of water and high quality ultrasonic solution). The cleaning device works by creating ultrasonic waves that generates microscopic bubbles that caves in vigorously within the cleaning liquid.
The process is called as cavitation which actually removes all the contaminants and fine particles, bonded to the sieves’ surface. The entire process involved is Eco-friendly and hence it is gentler as compared to the conventional sieve cleaning methods.
Ultrasonic cleaner for sieves are now available at online stores such as Amazon and eBay. You can choose the device that fulfills your requirements completely.
