Description

Technical Field

[0001] The present invention relates to the technical field of kitchen waste and food waste treatment, and specifically to a method for treating kitchen waste and food waste with yeast to prepare yeast powder. Background Art

[0002] Kitchen waste and food waste generally refer to degradable organic waste generated in daily life, especially waste generated from kitchen activities. Their main characteristic is that they all contain a large amount of organic matter, belonging to recyclable and degradable waste. Through effective garbage classification and treatment, the impact of these wastes on the environment can be reduced.

[0003] If untreated kitchen waste and food waste are not effectively treated for a long time, the amount of garbage accumulation will increase, and the treatment pressure on landfills and incineration plants will be aggravated, resulting in waste of land resources and energy resources. Moreover, it is easy to generate harmful gases (such as methane) through fermentation. These gases not only pollute the air quality but also have a negative impact on climate change.

[0004] Most of the existing treatment methods for kitchen waste and food waste have a low recovery and utilization rate of organic matter in kitchen waste and food waste, resulting in waste of resources. Summary of the Invention

[0005] The purpose of the present invention is to provide a method for treating kitchen waste and food waste with yeast to prepare yeast powder, so as to solve the problem that most of the existing treatment methods for kitchen waste and food waste have a low recovery and utilization rate of organic matter in kitchen waste and food waste, resulting in waste of resources.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A method for treating kitchen waste and food waste with yeast to prepare yeast powder, comprising the following steps:

[0007] Step (1), transferring kitchen waste and food waste to an aqueous phase, and adding BP15 and / or PE-100;

[0008] Step (2), inoculating yeast and culturing to produce yeast powder.

[0009] Preferably, the temperature for adding BP15 and / or PE-100 in step (1) is normal temperature.

[0010] Preferably, the type of yeast in step (2) is YX-6 or YX-9.

[0011] The present invention has at least the following beneficial effects:

[0012] A method for treating food waste and kitchen waste with yeast to prepare yeast powder provided by the present invention can not only effectively recycle and utilize the organic matter therein, but also prepare high-quality yeast powder, achieving the maximum utilization of resources. Detailed implementation manners

[0013] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
