Embodiment 1

[0084] Extract 20 kg of black tea, 30 kg of Fuzhuan black tea, 30 kg of bamboo leaves, and 2 kg of hawthorn, dry, pulverize, sieve to 80 mesh, distill and extract twice, and concentrate the extract in centrifugal vacuum to obtain a concentrate. Add ethanol to the concentrate to precipitate. The optimized process is leaching solvent 75% ethanol, material-to-liquid ratio 1:60 (g / mL), temperature 70°C, degree of fragmentation 80 mesh, leaching stages 2, leaching time 2 hours for 1st stage, and leaching time for 2nd stage After 0.5h, the extraction rate was 35.98%. The obtained precipitate was washed with absolute ethanol, anhydrous ether and acetone in turn, and then sent into a vacuum crystallizer. The pressure drops and the solution boils and cools down. Adjust the pumping rate of the vacuum system to reduce the pressure and temperature in the device according to the predetermined level until it reaches the predetermined level. Keep the solution in the crystallizer circulatin...

Embodiment 2

[0086] Extract 2 kg of black tea, 3 kg of Fuzhuan black tea, 3 kg of bamboo leaves, and 2 kg of hawthorn, dry, pulverize, sieve to 80 mesh, distill and extract twice, and concentrate the extract in a centrifugal vacuum to obtain a concentrate. Add ethanol to the concentrate to precipitate.

Abstract

The invention relates to the technical field of feed for livestock, poultry and fish, particularly relates to an environment-friendly tea feed which is a mixture of black tea, Poria brick dark tea, bamboo leaf and hawthorn, and aims to increase utilization efficiency of nutrients in feeds. The invention adopts the technical scheme as follows: the environment-friendly tea feed is made from the mixture of the following four ingredients in percentage by weight: 20% of black tea, 30% of Poria brick dark tea, 30% of bamboo leaves and 20% of hawthorn and is in a granule form. In the prior art, a large number of old tea leaves which grow after tea harvest in spring and summer or grow in autumn and winter are discarded to cause a large waste of tea resources, the content of deep-processed tea substances accounts for about 70% of tea dry weight, and a large number of nutrient residues occur in tea waste and tea seed cake. The invention achieves the purposes of efficient utilization of low-grade tea, large-scale manufacture and global marketing; and is significant in promoting development of new feed additive products, enhancing international competitiveness of feed amino acid products, promoting development, production and application of new feed additives containing plant extracts, achieving comprehensive utilization of new feed additives containing plant extracts, reducing antibiotics and other chemicals in feed additives, developing special feed products and increasing the value added of tea.

Description

Technical field: [0001] The invention aims at the technical field of feed for livestock, poultry and fish, and specifically relates to the mixed preparation of black tea, fuzhuan black tea, bamboo leaves and hawthorn, has the function of improving the availability of nutrients in the feed, and adopts environmentally friendly green crystalline feed. Background technique: [0002] feed [0003] The general term for the food of animals raised by all people. In a narrower sense, general feed mainly refers to the food of animals raised in agriculture or pasture. Feed includes soybean, soybean meal, corn, fish meal, amino acid, miscellaneous meal, additives, whey powder, oil, meat and bone meal, grain, sweet sorghum and more than ten varieties of feed materials. [0004] Feedstuffs are classified according to the International Classification: [0005] 1. Rough feed (1-00-000) refers to a type of feed with a crude fiber content of more than 18% in dry matter, mainly including hay...
