The liquid material that the hydrolysis formed contains solid materials such as grease, amino acid stoste and bone sediment, therefore the solid material proportion in the hydrolysis tank is great, and the storage tank is located the hydrolysis tank under, through arranging material straight tube intercommunication hydrolysis tank and storage tank, reduces the pipeline and blocks up the probability.

The storage tank is used for depositing the material of hydrolysising, and is concrete, and the storage tank bottom is toper or spherical, does benefit to solid materials such as guide bone sediment because of density subsides to gather and discharge, and the mixed material who gets rid of part solid material discharges via the bin outlet.

The grease separator is lower than the storage tank to satisfy the use of gravity flow pipeline between storage tank and the grease separator. The top end of the storage tank is higher than the grease discharge hole at the top end of the grease separator, so that the grease separator can be filled with the hydrolysate flowing out of the storage tank, an oil-water phase interface in the grease separator rises when the storage tank continuously discharges the grease, the grease is promoted to be discharged through the grease discharge hole, and after standing oil-water separation, the amino acid stock solution is discharged through the amino acid stock solution discharge hole on the side wall; after standing, solid materials such as bone residues and the like settle and accumulate at the bottom of the grease separator and are discharged through a second slag discharge port. Preferably, the feed opening is arranged in the side wall of the grease separator.

The top of grease separator is less than the top of storage tank, and grease separator is located the side of storage tank promptly, and pipeline length between storage tank and the grease separator diminishes control, also helps reducing the pipeline jam probability.

The oil discharge port of the oil separator is communicated with the oil tank, and the amino acid stock solution discharge port is communicated with the stock solution tank.
