Embodiment Construction
[0025] Such as figure 1 As shown, the preparation method of the pineapple extract feed additive of the present invention is to use biological enzymolysis, ultrasonic extraction, and ethanol reflux extraction to extract the active ingredients in pineapple and mix them with pine needle powder, plant grass powder, etc. in a certain proportion.
[0026] The main process steps include:
[0027] Step 1: Rinse the raw pineapple leaves, fruit and skin, and shorten them;
[0028] The second step: chop the raw materials and squeeze the juice, take the juice and add cellulase in the storage tank for biological enzymolysis, the temperature is 40 ℃ ~ 60 ℃, after 3.5 hours; ℃~65℃, specific gravity 1.35, take the liquid and filter to get the first filtrate;
[0029] The third step: add water to soak the remaining slag after squeezing the juice, add 10 times the amount of 70% to 95% ethanol, boil for 1 hour, the steam pressure is 0.5Mpa, filter after the first alcohol extraction; respective...
