The invention provides a grape 
branch fermented feed preparation process and equipment based on a biological 
fermentation technology. The preparation process mainly comprises the following steps of S1, washing and soaking collected grape branches, and introducing 
ozone water to eliminate 
pesticide residues; S2, crushing the pretreated grape branches, performing high-pressure sterilization, and adding a mixed bacterium suspension for modified 
fermentation; S3, premixing the modified grape 
branch powder with 
cottonseed meal, 
fish meal, 
meat and bone meal, distillers' grains, rice 
bran, 
bagasse,wheat 
bran, 
corn flour and 
calcium hydrophosphate, and then adding 
fermentation liquor; and S4, stacking the fermented materials into long piles with the same length and the same height at the bottomof a fermentation chamber, performing covering fermentation, and conveying the fermented grape 
branch fermented feed into a granulator through a conveying device for 
granulation. In conclusion, the method has advantages of advanced process, perfect scheme, novel equipment and the like.
