Technical Field

[0001] The utility model relates to the technical field of kitchen waste treatment, in particular to a sand removal device for kitchen waste slurry. Background Technique

[0002] Kitchen waste, also known as swill, refers to the waste generated in residents' daily life, food processing, catering services, unit meal supply and other activities; its main components include residues of rice and flour foods, vegetables, animal and vegetable oils, meat bones, etc.; kitchen waste is prone to rot and deteriorate, has a strong odor, and is also rich in nutrients, with certain recycling value. After recycling and processing, it can be converted into organic fertilizers, animal feeds, and can also generate energy such as biogas.

[0003] In the traditional process of kitchen waste treatment, after passing through processes such as screening, crushing, pulping, oil extraction, anaerobic digestion, and dehydration, reduction, harmlessness, and resource utilization are achieved.
