Does the high temperature generated during the granulation process of pine needle powder have an imp

Pine needles contain volatile oils, resins, chlorophyll, plant hormones, phytoncides, unknown growth factors and other bioactive substances, which will have a certain loss at high temperatures, so the high temperature generated by pine needle powder in the granulation process has an impact on the quality of pine needles themselves.

Pine needle powder is made from the leaves of Masson pine, Huangshan pine, black pine, red pine, larch, pine tabuliformis, pine sylvestris, spruce and fir, which is rich in crude protein, fat, trace elements and vitamins, etc., and is a new type of livestock and poultry feed additive, containing high nutritional value. Used as livestock and poultry feed additives or direct feeding of livestock and poultry, it can not only save feed and reduce costs, but also promote the growth and development of livestock and poultry, enhance disease resistance and improve reproductive function.

The processing process of pine needle powder is as follows: raw materials (pine branches) are collected, transported into the factory, unloaded, stacked, defoliated, chopped, dried, crushed, and packaged as finished products. The main equipment includes defoliator, shredder, dryer, crusher and gas supply and other auxiliary equipment.

The temperature should be controlled at 80 90 during drying, and the moisture should be sampled regularly. When the moisture content of the raw material drops to 8% to 10%, it can be discharged and crushed. The crushed pine needle powder can be pouched.

When packing, black plastic packaging bags must be used, stored in a dark, ventilated, dry and clean room, and the storage period should not exceed two months. Otherwise, the vitamins contained in pine needle powder are easily lost.

Geriespora cultures and gamma aminobutyric acid.

The processing method of pine needle powder is as follows:

1. Collection: Pine needles can be collected all year round, but it is most suitable when the moisture content is low in autumn and winter and the organic matter content in the nutrients is high. At this time, it can be carried out in combination with forest harvesting and tending pruning.

Generally, if it is picked by hand, 3-5 kg of pine needles can be collected per hour, and 500 kg per hour can be collected with TO-1-560 defoliator.

2. Drying: Spread the picked pine needles in a shaded and ventilated place for natural drying, spread out with a thickness of 5-8 cm, and be careful not to stack them for too long or dry them in the sun, so as not to affect the quality of the products. The natural drying time is 4-15 days, and the weight of the fresh product after drying is about 50%, and the water content drops to less than 12%, which can be crushed.

3. Crushing: The dried pine needles are ground and crushed with a crusher, and the actual production efficiency of the pine needles with a water content of less than 12% is generally about 80 kg per hour.

4. Packaging: Pine needle powder is best sealed and packaged in nylon bags and plastic bags, which can be stored for a long time, such as packaging in sacks, which is not conducive to long-term storage.

6. Storage: The warehouse for storing pine needle powder should be protected from light, ventilation, drying, and cleaning, and the ground of ordinary rooms should be supported to avoid moisture. The storage time is closely related to the quality of the product.

According to the test, the Masson pine needle powder with a water content of 10% can be stored in a standard warehouse for two months, and the carotene will be lost by 46%.

A powdered or granular product processed from fresh pine twigs and leaves. Also known as acerola vitamin powder.

In 1935, the Soviet Union used fresh pine needles as supplementary feed for poultry and poultry, and the first pine needle powder processing plant was established in 1955, which has grown to 350 processing plants by 1977, with an annual output of 150,000 tons of pine needle powder. China began to develop pine needle powder in 1979, and by the end of 1988, there were 160 pine needle powder processing plants in operation across the country, with an annual output of 60,000 tons. In addition, pine needle powder is also produced in Canada, Romania and Czechoslovakia.

The main raw materials for the production of pine needle powder in China are the young branches and leaves of Masson pine, Huangshan pine, red pine, black pine, Korean pine, Yunnan pine, and Chinese pine.

Nature: powdery or granular, pine needle powder is light green in appearance, non-toxic, and has a coniferous fragrance. Contains nutrients such as carotenoids, chlorophyll, fat-soluble and water-soluble vitamins, crude proteins, hormones, phytoncides, and trace elements.

Processing includes raw material collection, defoliation, shredding, drying, crushing, packaging, storage and other processes. The raw materials collected by machinery are not less than 60% fresh needles, no more than 30% lignified branches, no more than 10% organic impurities (broadleaves, etc.), and no more than inorganic impurities. The defoliation of branches adopts a defoliating machine, which requires the degree of defoliation to reach about 90%.

The length of the young branches and leaves is 30 40 mm, and the material is soft and conducive to drying. The drying equipment can be a vibrating dryer or an air flow drying device. Dry and young branches and leaves, crushed with a hammer crusher, the particle size is best controlled below millimeters, pine needle powder is packaged in black or colored plastic bags, jacketed in woven bags, stored in a dark, ventilated, dry and clean warehouse, to avoid the loss of chlorophyll and carotene in the powder.

Product quality. Chinese pine needle powder is divided into 3 grades, and the quality indicators are shown in the following table.

Use In livestock and poultry breeding, pine needle powder can be used as additives for mixed feed, and can also be directly used as supplementary feed in livestock and poultry rations. Pine needle powder has the effect of disease resistance, fast weight gain, egg production and feed saving for all kinds of livestock and poultry. In agricultural breeding, pine needle powder has a strong bactericidal effect because it contains phytoncides, so pine needle powder is used for disinfection and sterilization of crop seeds before sowing to prevent bacterial damage to crops.

In the adhesive, pine needle powder can replace all the fillers in the resin as a filler, and when the pine needle powder and resin mixture are pressed, the flow performance on the wood chip is good, and the gluing quality is high. Pine needle powder can be used as an extraction raw material for pine needle paste.

It has an impact, but it is not serious, if you want to change the color of the egg, it is recommended that you use yellow pine needle powder, you can go to Henan Everbright Fengyuan which to buy, I am using the factory's products, the quality is good!

Pine needle powder works very well on laying hens, improving the color depth of egg yolk. Linqu County, Shandong Province, Chinachem Protein Feed Factory pine needle powder. **0536／3478111

It's okay, but do a good job of adding fine powder in proportion, Pu powder is difficult to use strictly in proportion due to the purity and fineness, it is recommended to use fine powder, I myself am also engaged in breeding, calculated the cost, the surface ** fine powder is more expensive than Pu powder, but it is still more cost-effective than Pu powder, fine powder is generally 2 to 3 can be, more than a dozen of general powder I added are not fine powder effect, Guangda Fengyuan that factory has the production of fine powder, I am using, good

It won't have an effect, pine needle powder has a good effect on animals, in short, it's good.

Excuse me, what kind of pine flower needle is fine powder?

Pine needle powder is a livestock and poultry feed additive with high nutritional value that is being developed. The use of pine needle resources to develop feed production has a history of 40 years in the world, and the production has been industrialized.

Since the 70s of the 20th century, the Institute of Forestry and Chemistry of the Chinese Academy of Forestry was the first to develop pine needle powder, and the test was successful in 1979. In 1981, the first factory production of pine needle powder feed factory was built, by 1985 35 pine needle powder factories were built in the country, and by 2000 there were more than 680 pine needle processing factories in the country; The output of pine needle powder has also increased from 10,000 tons in 1985 to more than 13 million tons in 2000, and pine needle products have increased pine needle chlorophyll-carotene ointment, pine needle carotene powder, pine needle protein vitamin concentrate, pine needle chlorophyll powder and so on from a single pine needle powder feed. The processing technology of pine needles has also developed from the traditional simple process of drying and crushing to the modern production process of efficient and comprehensive utilization.

Since 1979, the Institute of Forestry and Chemistry of the Chinese Academy of Forestry and other units have conducted research on the use of pine needle powder or pine needle active substances as feed additives, and established professional standards for pine needle powder feed in China.
