Clever freshwater fish soil smell

Freshwater fish is not only delicious but also packed with nutrients, making it a great addition to any meal. However, it often comes with a strong earthy odor that can be off-putting if not properly handled. Fortunately, there are several effective and simple methods to eliminate this unpleasant smell before cooking. Here are some practical tips you can try at home. First, after cleaning the fish thoroughly, soak it in cold water mixed with a little vinegar and pepper. This combination helps neutralize the earthy smell while also enhancing the flavor of the fish. The vinegar works to break down the compounds responsible for the odor, while the pepper adds a nice kick. Second, you can use a saltwater solution. For live fish, soak them in a pot of water with about 25 grams of salt for one hour. The salt helps draw out impurities and blood from the fish, reducing the earthy scent. Even for dead fish, soaking them in salt water for two hours can significantly reduce the muddy or earthy smell. Third, when preparing carp, don't forget to remove the two white ribs located on either side of the back. These ribs contain the "special helium" — a term used to describe the part that contributes to the fish's strong smell. Removing them before cooking ensures a cleaner, more pleasant taste. Lastly, another effective method involves using tea. For a fish weighing between 500 to 1000 grams, prepare a cup of strong tea and dilute it with enough water. Soak the fish in this light tea solution for 5 to 10 minutes. The tannins in the tea help absorb and neutralize the unwanted odors, leaving the fish fresh and clean. These methods are easy to follow and can make a big difference in the final taste of your freshwater fish dish. Whether you're a seasoned cook or just starting out, these tips will help you enjoy the full flavor of your meal without the unpleasant earthy aroma.

Roundness Tester

A roundness tester is a measuring tool that uses the rotation axis method to measure the roundness error of a workpiece. The roundness tester is divided into sensor rotary and workbench rotary. During measurement, the measured part is installed concentric with the precision shaft system, and the precision shaft is equipped with an inductive length sensor or workbench for precise circular motion. The roundness meter consists of an instrument's sensor, amplifier, filter, and output device. If the instrument is equipped with a computer, the computer is also included in this system.

A roundness tester is a precision instrument used to measure the out-of-roundness of a rotating surface (shaft, hole, or spherical surface) of a component. There are usually two types: small desktop, where the workpiece is mounted on a rotating workbench and the measuring head is mounted on a fixed column; and Large floor mounted, with the workpiece installed on a fixed workbench and the measuring head installed on the rotating spindle. During measurement, the measuring head contacts the workpiece's surface, and the instrument's rotating part (workbench or spindle) rotates for one cycle. Due to the extremely high accuracy of the supporting bearings in the rotating part, the measuring head will generate a high-precision circular trajectory on the measured surface during rotation. The out-of-roundness of the measured surface causes the measuring head to shift and transform into an electrical (or pneumatic) signal. After amplification, it can be automatically recorded on a circular recording paper, and the out-of-roundness of each part can be directly read out for accuracy evaluation and process analysis and widely used in precision bearings, machine tools, and instrument manufacturing industries.

The Roundness Testeradopts a radius measurement method and operates in a rotating manner. The rotation axis system of the roundness meter adopts a high-precision air floating spindle as the measurement reference; The electrical part of the roundness tester is composed of advanced computers, precision circular grating sensors, and precision inductance displacement sensors. The circular grating sensors and precision inductance displacement sensors measure angle and radial displacement, ensuring the accuracy of measuring the angular displacement and radial value of the workpiece; The roundness meter measurement software adopts a roundness measurement software based on the Chinese version of WinXP operating system platform, completing data collection, processing, and measurement data management.
