Embodiment 1

[0051] A kitchen waste enzymatic hydrolysis treatment process, comprising the following steps:

[0052] (1) Physical crushing: 50kg of kitchen waste that has been sorted and removed from plastic bags, chopsticks, and sundries passes through the crusher and crushed into a paste-like substance, with particles smaller than 60 mesh;

[0053] (2) Cooking: Add 50kg of water to the pasty material worth in step (1) according to the quality of the raw material, stir it into a slurry, heat it to 98°C while stirring, and keep it warm for 2 hours. , the reaction vessel is required to be sealed to avoid water vapor leakage;

[0054] (3) Three-phase separation: The slurry obtained in step (2) has already appeared in a three-phase state of oil, water and slag. Through three-phase horizontal centrifugation, the oil phase is separated, and a total of 14L of kitchen waste oil is collected; a small amount The solid and viscous aqueous phase goes to the next step;

[0055] (4) Biological enzyma...

Embodiment 2

[0065] A kitchen waste enzymatic hydrolysis treatment process, comprising the following steps:

[0066] (1) Physical crushing: 100kg of kitchen waste that has been sorted and removed from plastic bags, chopsticks, and sundries passes through the crusher and crushed into a paste-like substance, with particles smaller than 60 mesh;

[0067] (2) Cooking: Add 100kg of water to the pasty material in step (1) according to the quality of the raw material, stir it into a slurry, heat it to 100°C while stirring, and keep it warm for 1.5 hours. The reaction vessel is required to be sealed to avoid water vapor leakage;

[0068] (3) Three-phase separation: After step (2), the slurry has already appeared in a three-phase state of oil, water and slag. Through three-phase horizontal centrifugal separation, the oil phase is separated, and a total of 28L of kitchen waste oil is collected; a small amount of solid Enter the next step with the viscous aqueous phase;

[0069] (4) Biological enzy...

Embodiment 3

[0079] A kitchen waste enzymatic hydrolysis treatment process, comprising the following steps:

[0080] (1) Physical crushing: 80kg of kitchen waste that has been sorted and removed from plastic bags, chopsticks, and sundries passes through the crusher and crushed into a paste-like substance, with particles smaller than 60 mesh;

[0081] (2) Cooking: Add 80kg of water to the paste material obtained in step (1) according to the quality of the raw material, stir it into a slurry, heat it to 93°C while stirring, and keep it warm for 2.5 hours. When heating and keeping warm, The reaction vessel is required to be sealed to avoid water vapor leakage;

[0082] (3) Three-phase separation: After step (2), the slurry has already appeared in a three-phase state of oil, water and slag. Through three-phase horizontal centrifugal separation, the oil phase is separated, and a total of 22L of kitchen waste oil is collected; a small amount of solid Enter the next step with the viscous aqueous...

Abstract

The invention discloses a kitchen waste enzymolysis treatment process. The kitchen waste enzymolysis treatment process comprises the following steps of (1) physical crushing, (2) cooking, (3) three-phase separation, (4) biological enzymolysis, (5) multi-stage filtration, (6) resin treatment, (7) solid drying and blending, (8) liquid blending, and (9) filling, packaging and warehousing. By the adoption of the process, only one-time temperature rise is needed, the treatment time is 8-10h, a product can be stored for 6-12 months at the room temperature through an anticorrosion method after nutrients are preserved, the product is not prone to being rotted and attracting mosquitoes, the production process is short, the automation degree is high, and potential safety hazards such as food entering do not exist.

Description

technical field [0001] The invention belongs to the technical field of kitchen waste treatment, and in particular relates to a kitchen waste enzymatic treatment process. Background technique [0002] With the continuous growth of my country's population and the continuous improvement of residents' living standards, my country's catering industry has also developed rapidly. With the rapid development of the catering industry, the accompanying catering waste has also begun to pile up like mountains. The amount of catering waste in my country is growing rapidly year by year. According to the data, in 2018, the national catering waste generation amounted to about 108 million tons, and in 2020, the national catering waste generation is estimated to reach 119 million tons. The large-scale centralized treatment of food waste mainly includes anaerobic fermentation, aerobic composting, microbial treatment, and physical drying treatment. Since most domestic enterprises enter the fie...
