Embodiment 1

[0026] Embodiment 1, in the high-protein alfalfa fine leaf powder processing method of the present invention, at first alfalfa grass is cut into 8cm long segment, makes alfalfa stem long and heavy and is easy to dry the back stem and leaf separation; High temperature oven dry 3 seconds , the inlet temperature is 900-1100°C, the outlet temperature is 70-80°C, the moisture content of alfalfa stems is 16%, and the moisture content of leaves is 10%. Fall, so that the stem leaves are easy to separate; the hammer mill (this pulverizer is a conventional product on the market) of 500r / min is pulverized with the rotating speed without sieve. Heavy; the leaves are completely crushed, and the crushed body is lighter; at the same time, the leaves can be completely detached from the stem, and the separation rate and work efficiency of the leaves can also be improved; use a "positive airflow" type fan with a wind speed of 0.2m / s to crush The stems and leaves are separated, the heavier stems...

Embodiment 2

[0027] Embodiment 2, in the high-protein alfalfa fine leaf powder processing method of the present invention, at first the alfalfa grass is cut into 12cm long segments, so that the alfalfa stems are long and heavy and easy to dry and the stems and leaves are separated; high temperature drying for 3 seconds , the inlet temperature is 900-1100°C, the outlet temperature is 70-80°C, the moisture content of alfalfa stems is 17%, and the moisture content of leaves is 5%. It is easy to fall, so that the stems and leaves are easy to separate; use a hammer mill with a speed of 500r / min without a sieve to crush. Under this crushing condition, the stems are not completely crushed, and the crushed body is heavy; the leaves are completely crushed, and the crushed body Lighter; at the same time, the leaves can be completely detached from the stems, and the separation rate and work efficiency of the leaves can be improved; the crushed stems and leaves can be separated with a "positive pressur...

Abstract

The invention belongs to the technical field of forage grass processing, in particular to a processing method of high-protein lucerne refined leaf meal. The processing method solves the problem of finish processing of lucerne. The invention has the technical scheme comprising the following steps of: from the budding period to the initial flowering period, cutting the lucerne into small segments which are 8cm long; when the lucerne is dried by using a high-temperature dehydrating method and the stem moisture is higher than 16 percent and the leaf moisture is lower than 13 percent, crushing with a hammer-type pulverizer without a sieve, and subsequently separating stems from leaves by using a positive-pressure airflow-type fan machine. The processing method can be widely applied to forage grass processing industry; and the lucerne refined leaf meal produced by the processing method can be widely applied to feeds for pigs and fowls.

Description

technical field [0001] The invention belongs to the technical field of forage processing, in particular to a method for processing high-protein alfalfa fine leaf powder. Background technique [0002] Alfalfa (Medicago sativa L.) is the perennial leguminous forage with the longest cultivation history and the largest area in the world. It can not only fertilize fields, increase crop production, but also raise livestock. Its nutritional value is even higher than that of some grain concentrates. It enjoys the reputation of "the king of forage" for its high yield, rich nutrition and good palatability. Alfalfa plays an important role in agricultural and animal husbandry production. It is an excellent forage grass for livestock. Whether it is green grass, hay, silage or made into grass powder, grass block and grass pellets, it has the characteristics of high quality. Due to the high feeding value and good palatability of alfalfa powder, the demand at home and abroad is strong. In...
