Sugar Test Sieve

What is a sugar test sieve?

Sugar test sieve are often used with standard sieve sets in conjunction with mechanical vibrating screens and other devices. The screening particle size varies depending on the type of sugar and testing standards: refined sugars commonly use apertures of 850μm, 600μm, 500μm, and 355μm. White sugar testing generally covers a range of 0.28mm to 2.5mm. Powdered sugar screening can be refined to 212μm or even smaller. In terms of output, experimental equipment can process approximately 200g of sample at a time, and screening takes 10-20 minutes. Industrial-grade sugar sieves have higher outputs. High-flow screens can increase sugar production by 150%-170% compared to standard screens. Some vibrating screening equipment can reach over 100 tons per hour, which is affected by the screen aperture, porosity, vibration parameters, and sugar condition.

Sugar Test Sieve usually consists of a set of standard sieves, sieve frames, chassis and covers, which separate sugar products by particle size through mechanical vibration or manual operation. Its core function is to measure the particle size distribution of sugar products to ensure that they meet production or use requirements.

How does the sugar test sieve work?

First, place the sugar product to be tested into the upper sieve to complete the loading. Then, mechanical vibration is used to make the sugar product move on the sieve, allowing fine sugar particles to pass through the sieve and fall into the lower layer, while coarse sugar particles remain on the sieve to achieve screening. Then, the different apertures of each sieve are used to classify the sugar products according to particle size. Finally, the sugar products on each sieve are taken out, weighed, and the particle size distribution is calculated to complete the weighing.

The structure of sugar test sieve

The screen is made of stainless steel or brass, with standard aperture sizes such as 20, 40, and 60 mesh. The screen frame, which secures the screen, is typically made of stainless steel or plastic. The bottom tray collects the powdered sugar after it passes through the finest sieve. A cover prevents splashing during the screening process. A vibrating device automates the screening process, improving efficiency and accuracy.

Application of sugar test sieve

Sugar Test Sieve is used in food and beverage, agriculture, scientific research laboratories, and traditional Chinese medicine preparations to assist in impurity filtration, maturity determination, sample analysis, and drug quality control.

Food and beverage industry: In the process of fruit juice production, it is necessary to first use a sieve to filter out solid impurities such as pulp and peel, and then use a saccharimeter to measure the sugar content of the juice. Through sieves with different apertures, sugar test sieve can separate pulp particles of different sizes.

 Agricultural field: In the process of fruit and vegetable cultivation, the maturity and quality of fruits or vegetables can be judged by measuring their sugar content. By measuring the sugar content of different varieties of fruits and vegetables through sugar test sieve, varieties with higher sugar content can be screened out for breeding and promotion.

Scientific research laboratory: In scientific research laboratories, sugar test sieve can be used to analyze various samples containing sugar, such as plant extracts, fermentation broth, etc. Through screening and sugar content measurement, the distribution, content and properties of sugar can be studied.

Traditional Chinese medicine preparations: In the traditional Chinese medicine preparation industry, some traditional Chinese medicine ingredients contain sugar, and sugar content needs to be tested through sugar test sieve to ensure the quality of the medicine.

How to use the sugar test sieve for testing

The steps for testing sugar content using the Sugar Test Sieve typically include five routine steps: preparing the sample, preparing the juice, using the sugar test sieve, determining the sugar content, and interpreting the results.

Prepare the sample: Select fresh fruit or vegetable samples, wash and remove the skin, and keep the sample intact.

Prepare the juice: Chop or squeeze the sample to release the juice, and prepare the juice sample to be tested.

Use the sugar test sieve: Place the sugar test sieve on the container, pour the juice sample to be tested, and gently shake or press to make the juice pass through the sieve meshs.

Measure the sugar content: The juice flowing out through the sieve meshs contains plant cells, and the sugar molecules are small. The sweetness of the sample can be judged by measuring the sugar content in these juices.

Read the results: According to the test results, the sugar content of the sample can be judged.

How do I use Sugar Test Sieve?

The Sugar Test Sieve can process various types of sugar, including granulated sugar, brown sugar, rock sugar, and fructose. During operation, the sugar to be sieved is evenly placed on the top sieve, and sieves of different mesh sizes are stacked according to the desired particle size. After starting the sieve, the sugar passes through the sieve layer by layer under vibration or shaking. The finest sugar is discharged from the bottom outlet, while coarser particles remain on the upper sieves. Different types of sugar require different mesh sizes depending on the intended use; for example, granulated sugar commonly uses 40–80 mesh, brown sugar and rock sugar use 20–60 mesh, and fructose uses 60 mesh or higher to ensure uniform particle size and stable sieving results.

What are the disadvantages of sugar test sieve?

The disadvantages of the Sugar Test Sieve are its limited accuracy and susceptibility to temperature, humidity, and operating methods, leading to unstable results. Sieve aperture size and sample variations can also affect the measurement, requiring multiple repetitions.

Applicable products have limitations: The design and aperture size of sugar test sieve may not be suitable for all types of agricultural products, and some samples with special shapes or high viscosity may not be screened effectively.

There is a problem of insufficient screening accuracy: Sugar test sieve may have insufficient screening accuracy due to factors such as the screen material, aperture size, or vibration frequency during the screening process. This may make the screening results inaccurate and fail to accurately reflect the true sugar content of the substance being tested.

Improper sample handling: Before sugar test sieve is used, the sample needs to be properly handled. If the sample is not handled properly, such as insufficient mixing, uneven sampling, etc., it may affect the accuracy of the screening results.

Error in sugar content particle size distribution: Since sugar products are prone to moisture absorption or agglomeration, it may cause errors in particle size distribution measurement. Inaccurate measurement results affect quality control. Sugar test sieves dry sugar products before sieving or use anti-caking agents.

Selection suggestions for sugar test sieves

Choose the sieve according to the particle size range: the sieve aperture should be selected according to the particle size distribution of the sugar product.

Choose the sieve frame diameter according to the sample volume: choose a sieve frame with a larger diameter when the sample volume is large.

Choose manual or mechanical vibration according to needs: mechanical vibration screening efficiency is higher and suitable for large-scale testing.

Consider the material: stainless steel is corrosion-resistant, easy to clean, and suitable for long-term use.
