How to distinguish true and false fish meal?

With the development of the aquaculture industry, the demand for fishmeal is increasing day by day. Some unscrupulous traders have taken the opportunity to make doping and make huge profits. Farms (households) should improve their ability to identify true and false fishmeal.

The standard fish meal is generally a powdery material with a uniform particle size and a slightly greasy appearance. A large number of loosely powdered fish muscle fibers and a small amount of bone spurs, fish scales, fish eyes and the like can be seen. The color is light yellow, yellowish brown or brownish brown. It has a loose touch, no agglomeration, no stickiness, no clumps, a rich grilled fish taste and a slight fishy smell. Overheated or high fat fishmeal will darken. If the color of the fishmeal is blackish red, the appearance is bleak, and the smell of burnt smell is a burnt fishmeal that causes spontaneous combustion due to improper storage. If fishmeal is dark brown, there is an oily odor that is a result of fat oxidation. If the fish meal has ammonia odor, it may be fatty degeneration in storage. If the fish is pink and gray or grayish yellow, the smell is thicker, the luster is not strong, the fibrous matter is more, the coarse looks like ash, easy to agglomerate, the powdery particles are smaller and more into small groups, the touch is easy to smash, but not The rare fish muscle fiber is adulterated fish meal, which needs further examination.

Installing Bullet Solar Camera
1. Understand how solar monitoring works
The solar Security Camera mainly relies on its attached solar panel to convert the solar light into electricity and charge the built-in battery for monitoring. The integrated inverter in the monitoring can also convert the DC power from the solar panel to AC power, so as to provide power when the sun comes out. It is stored in its rechargeable battery during the day, and its power can maintain the continuous work of solar monitoring at night.
2. What are the advantages of solar monitoring over ordinary monitoring
Unlike wired common monitoring, it does not need to run wires to connect it to the power supply. They connect to the home safety system via a Wi Fi connection rather than a data cable. As a result, they are true wireless security solutions that are easier to install. With wired cameras, you need to place them on the wall where the power cord runs, or close to the wall outlet. In contrast, you can install additional solar monitoring anywhere, even if there is no outlet nearby.
3. Which functions are necessary in solar monitoring
Camera resolution, field of view, solar panel wattage, night vision, motion activation, remote monitoring and smartphone alarm. The resolution of the camera determines the sharpness of the monitored safety picture. Look for models with High Definition (HD) cameras or better. The field of view describes the coverage of the camera. Security monitoring with a wider view is always better. Night vision and motion activation indicate whether the camera can see at night and start recording when it detects motion in the coverage area. The wattage of the solar panel paired with the security camera indicates how much power it can generate from sunlight. The battery panel with higher wattage can charge the attached battery faster and provide more power for monitoring. Smartphone alerts and remote monitoring are designed to help you monitor your home or office in the absence.
4. Whether the sun monitoring can continue to work in cloudy days
The answer is yes. The solar panels connected to the solar monitoring system generate less power in cloudy and rainy days, but the excess power stored in rechargeable batteries in sunny days can help them survive rainy and cloudy days.
