The fermentation process requires a certain amount of moisture, which is generally about 65%. For example, the water required for the production of a fertilizer feed using a type 1 and type 2 starter fertilizer is 60-65%, so that functional bacteria can normally reproduce. A simple way to judge is: grab a handful of material by hand, and see that the water is not dripping on the finger-tap is a generally appropriate standard. If you do not see the watermark, it is too dry. If you drip down, it is too wet. Too much or too little moisture is not conducive to fermentation: too little water, slow fermentation of microorganisms. Too much water increases the temperature slowly, and the ventilation is poor, forming a local anaerobic environment to promote the work of spoilage bacteria and produce odors.
When making materials, users should pay attention to the method of water conditioning. Here are some tips for adding water and precipitation. Users can refer to them. (1) It is necessary to grasp the principles of first, late, and gradually adding. If conditions permit, hot water should be added so that it will start quickly. Note that it is best to burn the water directly to 30-40°C instead of boiling the water and cooling it to 30-40°C (the beneficial microorganisms in the water have been killed). For example, when the production process of Jinbao fermentation bed is due to a large amount of excrement per day, it is not safe to use home water. (2) If, due to various reasons, excessive moisture in the material is affected and the speed of fermentation is affected, measures should be taken to reduce the moisture. Methods include spreading drying and adding straw powder, dry earth, sawdust, and glutinous rice to the material.
A spectrometer is a scientific instrument used to separate and measure spectral components of a physical phenomenon. Spectrometer is a broad term often used to describe instruments that measure a continuous variable of a phenomenon where the spectral components are somehow mixed. In visible light a spectrometer can separate white light and measure individual narrow bands of color, called a spectrum. A mass spectrometer measures the spectrum of the masses of the atoms or molecules present in a gas. The first spectrometers were used to split light into an array of separate colors. Spectrometers were developed in early studies of physics, astronomy, and chemistry. The capability of spectroscopy to determine chemical composition drove its advancement and continues to be one of its primary uses. Spectrometers are used in astronomy to analyze the chemical composition of stars and planets, and spectrometers gather data on the origin of the universe.
Examples of spectrometers are devices that separate particles, atoms, and molecules by their mass, momentum, or energy. These types of spectrometers are used in chemical analysis and particle physics.
