Crude Fiber Determination of Pinus massoniana Pollen

Crude Fiber Determination of Pinus massoniana Pollen

Pollen contains lysine, glutamic acid, tryptophan and other 21 kinds of human body amino acids, a variety of vitamins, iron, zinc and other trace elements and auxin, polyunsaturated fatty acids, etc., so there are all natural nutritional foods, The name of the concentrated nutrition library. Pollen also has the medicinal value of improving the body's comprehensive immune function, regulating gastrointestinal function, preventing and treating cardiovascular and cerebrovascular diseases, anti-cancer, liver protection and liver protection, and is a health product with extremely high nutritional value. In recent years, the study of pollen chemical composition has attracted the interest of many scientific researchers. The crude fiber analyzer is an instrument that specifically determines the crude fiber content.

Dietary fiber is a polysaccharide that cannot be absorbed and utilized by the human body and includes cellulose, hemicellulose, pectin and hydrocolloid substances. Although dietary fiber cannot be digested and absorbed in human body, it has many special physiological functions and is extremely important to human health, such as Reducing the incidence of chronic diseases such as intestine cancer, obesity, and coronary heart disease. Crude fiber is an integral part of dietary fiber and has important functions such as helping digestion and strengthening gastrointestinal function. In this paper, the content of crude fiber in different pollen was measured to provide a theoretical basis for the further study of chemical constituents in pollen.

Methods for measuring crude fiber include volumetric method, acid-alkali digestion method, neutral detergent method, acid washing method, etc. Among them, the acid-alkali digestion method is a more commonly used method. In this paper, coarse fibers were used to determine the coarse fibers in the pollen, ie, acid-alkali digestion was used.

Through the determination of the crude fiber tester, the content of cellulose in the pollen of Pinus massoniana was the highest, which was 36.15% (dry weight), which was an ideal choice for supplementing crude fiber. The cellulose content of other pollen was not significantly different, and the pollen content of Hawthorn was lowest. It is 5.03% (dry weight). Crude fiber has the function of promoting gastrointestinal motility and excreting toxins. Taking in certain crude fiber is good for the health, but excessive intake has certain side effects on health, such as affecting the digestion and absorption of proteins and other nutrients in the body. Cause abdominal discomfort, increase intestinal peristalsis and gas production, reduce the absorption of nutrients and so on. By comparing the crude fiber in different kinds of pollen, it can provide reference for people to purchase pollen, make reasonable diet and supplement dietary fiber, and provide basic data for pollen composition research and pollen deep processing.

Marine Electro-hydraulic Windlass

The windlass is installed on the main deck of the ship's bow, which is used for the ship to lift the anchor and drop the mooring cable.
Windlass can be divided into manual, electric, hydraulic, pneumatic, etc. according to the driving form.

The windlass can be divided into several specifications such as φ12--φ120mm according to the diameter of the anchor chain.
Windlass can be divided into single-sided and double-sided according to the distribution of drums.
The windlass is mainly composed of base, bracket, chain wheel, brake, chain wheel, gearbox, electric control system (except manual windlass), etc. Electric windlasses have electric motors, and hydraulic windlasses have hydraulic pump stations.
The main technical indicators of the windlass include the diameter of the anchor chain, the nominal speed of the anchor, the rated load, the supporting load, several levels of speed change, electrical system, etc. The installation of the windlass on the ship should ensure that the wrap angle between the anchor chain and the sprocket is 117-120°.
Electric windlass
The electric motor directly drives the windlass, and the drive shaft is driven by the gear box to work, and the structure is simple; it is generally suitable for windlasses with an anchor chain diameter of 16mm-93mm.
hydraulic windlass
It is suitable for windlass with anchor chain diameter of 16mm-120mm. Hydraulic windlasses are also called electro-hydraulic windlasses. It drives the oil pump with a motor, drives the motor with high-pressure oil, and then drives the transmission gear through a reducer (or no reducer). To make the windlass run, its structure is relatively compact and its volume is small. Now there has been an automatic hydraulic windlass, which is equipped with an anchor chain length sensor. When the anchor chain needs to be thrown out, the windlass will automatically stop; , can automatically decelerate; the anchor will automatically stop when it enters the anchor chain drum and is properly received.
