Citrus peel biomass energy particle and preparation method thereof by squeezing

Abstract

The invention discloses a citrus peel biomass energy particle and a preparation method thereof by squeezing. The biomass energy particle is formed by squeezing and then carrying out mechanical pressing on citrus peel, agroforestrial wastes and an antifermentive agent. The preparation method of the biomass energy particle comprises the steps of squeezing, smashing, mixing, drying and moulding. According to the invention, massive waste peel produced by processing citrus in a large scale can directly enter into a pipeline processing system, and a particle biomass energy fuel which is dense, has high energy density and thermal efficiency more than 80%, is easy to store and transport and is convenient to popularize and apply can be processed within several hours only, the fuel is an efficient and clean energy product, and the fuel has the advantages of good combustion characteristic, high burning rate, less dust, low chemical pollution emission and citrus flavour.

Description

technical field [0001] The invention relates to a biomass energy granule made from citrus peel as a raw material and a pressing preparation method thereof, in particular to a citrus peel biomass energy granule and a pressing preparation method thereof. technical background [0002] At present, my country has extensive research on the recycling and reuse of citrus peel waste, but most of them have limited processing scale, low decomposition conversion rate, long conversion cycle, excessive investment in equipment and insufficient output, and difficulty in popularization and application. And other issues. Taking the treatment of citrus peels as an example, the fresh peels after squeezing the juice or the peels after extracting citrus essential oils are mainly landfilled. With the increase of landfill, citrus peels will gradually acidify the soil around the landfill, and the area of ​​acidified soil will continue to expand. At the same time, there are three other resource util...

AI Technical Summary

Problems solved by technology

At the same time, there are three other resource utilization methods for citrus peel residues in my country: one is to produce protein feed, due to technical constraints and adaptability problems, there are only experimental reports on adding a small amount of citrus residues to feed poultry and livestock at this stage

The second is to make organic fertilizers. Due to the high water content of citrus peels and the high cost of composting, it is easy to cause re-pollution to the surrounding environment during the composting process.

The third is to produce biogas through fermentation. Due to the long production cycle of biogas and the difficulty of large-scale collection and utilization of biogas, it is also difficult to transform and utilize organic fertilizers and biogas production.

Due to the high moisture content of citrus peel, it is rich in sugar and pectin. If the traditional method is used to produce biomass pellets, drying at high temperature will easily cause them to coke, and the pellets produced are difficult to store for a long time because they are easy to ferment. However, there are no applications and reports on the use of citrus pomace to produce biomass energy.
