Process method for preparing liquid fertilizer from adventmilk

Abstract

The invention discloses a process method for preparing a liquid fertilizer from advent milk, wherein a filtering bin is used, and an electric lifting rod is fixed to the upper end surface of the inner cavity of the filtering bin. According to the invention, a milk product separation liquid can be subjected to filter pressing so as to carry out filter pressing on residues in the milk liquid while gas fed into a gas pipe through a gas pump can be discharged through multiple one-way exhaust valves so as to carry out air blowing on the milk liquid in the liquid storage tank, so that the residues of the milk liquid are filtered and separated three times, and the stored milk liquid can be prevented from solidifying to influence the mixing quality with other fertilizers; and compared with an existing process, the process of the invention has the advantages that the separated milk liquid can be stored, the situation that milk products need to be continuously and rapidly operated in the past is changed, and the vertical pipe can extend into a mixing barrel by different depths, so that the milk liquid can be fed into different layers of the to-be-mixed fertilizer, the efficiency of mixing the milk liquid with other fertilizers is higher, and the mixed liquid fertilizer can be quickly poured out.

Description

technical field [0001] The invention relates to the technical field of preparing fertilizers from milk, in particular to a process method for preparing liquid fertilizers from imminent milk. Background technique [0002] Milk is also called dairy products, which refer to various foods processed by using processed milk products as the main raw material, adding or not adding appropriate amounts of vitamins, minerals and other auxiliary materials, and using the conditions required by laws, regulations and standards. , also called cream products, which have a certain shelf life, expired will cause qualitative changes and cannot be eaten, so they can only be discarded and destroyed. There are also milk products separated into solid and liquid. The liquid is rich in a large amount of NPN nutrients and can be mixed into fertilizer raw materials. , used to make different fertilizers. [0003] In the existing process of preparing liquid fertilizer from imminent milk, in the process ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of processing method of preparing liquid fertilizer from milk at the expiration date, and solve the existing processing method of preparing liquid fertilizer from milk at the expiration date. In the process of processing, milk liquid is usually directly mixed with other fertilizers The raw materials are mixed, and the milk liquid is also mixed with unseparated residues. Direct mixing will affect the quality of the fertilizer, resulting in the failure to achieve the desired effect when used.
