Embodiment 1

[0061] Collect 50kg of kitchen waste (starch, protein, cellulose, lipids), the protein content after testing: 23.6%, after the collection process is manually sorted and managed to remove foreign objects, such as: plastic, iron parts, big bones, paper scraps, etc. , using mechanical dehydration equipment for dehydration pretreatment, so that the waste contains about 90% water and 15% oil. Put the pretreated material into the crusher to crush it. The crushed particle size is 40mm. The crushed material is transported to the belt drying system and dried at a drying temperature of 105°C for 4 hours until the moisture content is 20. %. Finally, microwave sterilization equipment was used for sterilization treatment. The sterilization temperature was 80°C for about 10 minutes to obtain feed additives. The moisture content was controlled at 10%, the protein content of the product was 22.7%, and the protein loss rate was 3.81%.

Embodiment 2

[0063] Collect 50kg of kitchen waste (starch, protein, cellulose, lipids), the protein content after testing: 23.6%, after the collection process is manually sorted and managed to remove foreign objects, such as: plastic, iron parts, big bones, paper scraps, etc. , using mechanical dehydration equipment for dehydration pretreatment, so that the waste contains about 90% water and 15% oil. Put the pretreated material into the crusher to crush it, the crushing particle size is 20mm, and then soak it in the sodium chloride salt solution, the concentration is 5‰ sodium chloride salt solution, the weight of the sodium chloride salt solution is the same as the solid waste Part ratio: 1:6, soak for 10 minutes, the upper oil layer part is separated and removed through the oil layer overflow system, the lower layer water and solid phase substances are dehydrated by belt filter press until the water content is about 65%. The belt speed is set at 12m / min, and the material that has passed ...

Embodiment 3

[0065] Take 50kg of kitchen waste (starch, protein, cellulose, lipids), the protein content after testing: 24.1%, after manual selection, remove foreign matter, such as: plastics, iron pieces, etc., and use mechanical dehydration equipment to dehydrate it. Treat the waste so that the waste contains about 80% water and about 8% oil. Put the pretreated material into the crusher to crush it, the crushing particle size is 50mm, add sodium chloride salt solution for soaking, its concentration is 2‰ sodium chloride salt solution, the weight part of sodium chloride salt solution is the same as solid waste Ratio: 1:4, soak for 15 minutes. The water content is reduced to 75% through the dehydration of the belt filter press. The belt speed of the belt filter press is 5m / min. The material that has passed the belt filter press is transported to the belt drying system and dried at 70°C. 7h, until the moisture content is 22%. Finally, microwave sterilization equipment was used to steriliz...

Abstract

The invention discloses a method for preparing feed additives by using table and kitchen wastes. The method comprises the steps of sorting and impurity-removing of the table and kitchen wastes, dewatering and deoiling pretreatment, crushing, soaking, pressure filtration for separation, low-temperature drying, microwave sterilization and packaging. The separated solids are made into the feed additives through processes of drying, microwave sterilization, metal detection and the like. By using the table and kitchen wastes for making the feed additives through a resource treatment method and by treating the solid wastes through a low-temperature drying and microwave sterilization method, the original nutrition of the table and kitchen wastes is effectively reserved and the prepared feed additives are enabled to be more nutritious; and at the same time, the quantity-reducing, harmless and resource treatment of the table and kitchen wastes are effectively realized, the wastes are turned into valuable things and the method is an important approach for saving land and resources and developing low-carbon and recycling economy.

Description

technical field [0001] The invention relates to the field of kitchen waste treatment, in particular to a method for preparing feed additives from kitchen waste. Background technique [0002] Kitchen waste is a general term for leftovers discarded by households and catering units. It is an important part of municipal solid waste, mainly including rice and flour food residues, vegetables, vegetable oils, animal oils, meat bones, fish bones, etc., containing starch, Cellulose, protein, lipid and inorganic salt, etc. The content of organic matter is high, the moisture content is high, it is easy to be corrupted and produces bad smell, it is inconvenient to collect and transport, the calorific value is low, and the back-end treatment is easy to produce secondary pollutants such as leachate, which not only pollutes the environment, but also seriously endangers people's health. [0003] At present, kitchen waste is directly fed to pigs to produce "swill pigs", waste oil in kitchen...
