Embodiment Construction
[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0017] The steps of the amino acid production process from kitchen waste of the present invention are:
[0018] 1. Kitchen waste treatment
[0019] 1) Cooking, kitchen waste cooking machine treatment, to achieve the effect of sterilization and oil dissolution,
[0020] 2) Squeeze, the cooked material is sent to the press to be squeezed to obtain residue and oil-water mixture;
[0021] 3) Treatment of slag and oil-water mixture, the slag is used as insect feed, and the oil-water mixture is mechanically separated by a horizontal oil-water slag three-phase separator to obtain oil, soup and residue; the residue is incorporated into the original slag as insect feed; Separation with a vertical oil-water separator to obtain bio-oil, which is used as biodiesel and chemical raw materials, and the soup is sterilized and concentrated at high temperature, ...

The invention discloses a technology for producing amino acid through kitchen wastes, which comprises the following steps of: 1, cooking: a kitchen waste cooking machine is utilized for processing to realize the sterilizing and oil dissolving effects; 2, squeezing: the cooked materials are fed into a squeezer to be squeezed, and residues and an oily water mixture are obtained; and 3, residues and oily water mixture treatment: the residues are used as inset feed, the oily water mixture is separated to obtained oil, cooking liquor and residues; the residues are mixed with the original residues to be used as the inset feed; the cooking liquor is sterilized at high temperature, and then proceeds to the next treatment process; the technology for producing amino acid is as follows: 1, the sterilized cooling liquor is hydrolyzed, so the protein is hydrolyzed into the amino acid; and the hydrolysis comprises A: enzyme hydrolysis: protein hydrolase is added into the cooking liquor for hydrolysis to obtain the amino acid; and B, acid hydrolysis: the acid is added into the cooking liquor to hydrolyze the protein in the cooking liquor to obtain the amino acid.
Description
technical field [0001] The invention relates to a process for producing amino acid from kitchen waste. Background technique [0002] The production processes of amino acids include synthesis and protein degradation. The process of protein degradation to produce amino acids includes hydrolysis and so on. As for the heavily polluted kitchen waste, which is rich in nutrition and contains a lot of protein, how to make effective use of these proteins to turn waste into wealth, generate income and reduce emissions, is safe and harmless to humans and animals, and achieve zero emissions and pollution-free, etc. Questions people are working on. Contents of the invention [0003] The purpose of the present invention is to provide a process for producing amino acid from kitchen waste. [0004] The invention aims to solve the problems that a large amount of protein in the existing nutrient-rich kitchen waste cannot be effectively utilized and pollutes the environment. [0005] The...
