Embodiment Construction

[0014] When the present invention is specifically implemented, the harvested alfalfa is bundled and placed in the air to a moisture content of 40%-50%, and then the alfalfa is put into a dryer for drying, and the moisture content of the dried alfalfa is 7%. -8%, the dried alfalfa is crushed and screened by a crushing and screening machine with a sieve diameter of 2mm-4mm. After crushing, the alfalfa is mixed with water vapor at a temperature of 100°C-200°C through a rotating agitator at a speed of 300rpm Stir, during the stirring process, add a chemical protectant with a content of 0.15%-0.22% of the content of the alfalfa. When the moisture content of the alfalfa is 10%-12%, use pressurized equipment and the diameter is between 5-mm15mm, the typical pressure The material is shaped and extruded by a 34-38Mpa die, and after cutting, it passes through a cooler so that the temperature around the alfalfa pellets is 5°C and the water content is 8%-10.5%, and then it is transported o...

Abstract

The invention discloses an alfalfa particle pressurized preparation method. The method comprises the following steps of: bundling harvested alfalfa and airing, then putting the alfalfa into a drying machine for drying, crushing the dried alfalfa by using a crushing machine and screening, mixing the crushed alfalfa with water vapor and stirring, adding a chemical protection substance in the stirring process, then forming and pressing the alfalfa by using a pressurization device and a pressing die, cutting the alfalfa, cooling the alfalfa through a cooler and then storing and transporting the alfalfa. The method has the advantages that the prepared alfalfa particles are high in quality and low in nutrition loss.

Description

technical field [0001] The invention relates to the technical field of alfalfa processing, in particular to a pressurized preparation method of alfalfa granules. Background technique [0002] my country's animal husbandry is in a critical period of development, and the deep-seated contradictions that affect and restrict the economic development of animal husbandry are constantly emerging. The total number of livestock has increased significantly and the output of pasture has decreased sharply. The quality and quantity of forage have become constraints for animal husbandry the primary issue of industry development. Alfalfa is rich in crude protein, high digestibility, good amino acid composition, more lysine, high protein biological value, rich vitamin content, especially high carotene content, B vitamins, vitamin C, There are also a lot of E and K content, rich in calcium, and the ratio of calcium to phosphorus is relatively balanced, good palatability, wide adaptability and...
