Desktop milk fat centrifuge‌The operation process is applicable to the standard physical and chemical testing of relative density and various fats in milk and dairy products using Babcock's method

It is a device used for separating fat components in dairy products (such as milk). Its operating principle is based on the action of centrifugal force, and the separation of components with large density differences is achieved through high-speed rotation.‌

‌Core working principle‌

The core principle of the desktop milk fat centrifuge is to use the centrifugal force generated by high-speed rotation to stratify the components of different densities in the sample. In the process of separating milk fat, fat molecules are pushed towards the upper part of the container due to their low density, while components with higher density such as water and protein deposit at the bottom, thus achieving effective separation.‌

2 The magnitude of centrifugal force is determined by both the rotational speed and the rotor radius, and can be calculated using the formula( F = m \\cdot r \\cdot \\omega^2 )Calculation, among which( F )For centrifugal force,( m )For the quality of the sample,( r )For the radius of the rotor,( \\omega )The angular velocity is proportional to the rotational speed.‌

‌Operation process and key steps‌

‌preparation‌Check whether the main body and rotor of the equipment are intact, select suitable centrifuge tubes (such as polypropylene material), and ensure that the weight of symmetrically placed centrifuge tubes is consistent to maintain balance.‌

‌Loading samples‌Inject the milk fat sample into the centrifuge tube, seal the tube mouth to prevent leakage, and then symmetrically place it into the rotor.‌

‌Set parameters‌Set the rotational speed based on the characteristics of the sample (e.grpmorgValue, time, and temperature (if it is a refrigeration model).‌

‌Start and Run‌Close the centrifuge cover and lock it, then start the device; If there is any abnormal vibration or noise during operation, the machine should be stopped immediately for inspection.‌

‌End operation‌After the rotor stops, open the lid and carefully remove the centrifuge tube to avoid disturbing and layering, and clean the rotor and cavity in a timely manner.‌

‌Precautions‌

‌balance control‌The equal weight centrifuge tube must be symmetrically placed, and the empty hole needs to be filled with a balance tube, otherwise it can beCan cause equipment vibration or damage.‌‌Parameter Settings‌The speed and time need to be adjusted according to experimental requirements. Insufficient speed may result in separation failure, while excessive speed may damage the centrifuge tube.‌

‌maintenance‌Regularly inspect the rotor for corrosion or cracks, and maintain the equipmentDry and clean to extend service life
