NOVELTY - Citrus fruit processing by-product zero discharge integrated treatment plant comprises a cutting machine (11) for cutting citrus fruit processing by-product (1), a crushing mill (12) for crushing the cut by-product, an initial processing device (10) comprising a raw material storage tank (13) for storing the milled citrus fruit processing by-product, a moisture control reservoir containing moisture control agent, a feed raw material reservoir for storing feed raw material powder, a mixer which receives the raw material from the raw material storage tank, and moisture control reservoir.    USE - Used as citrus fruit processing by-product zero discharge integrated treatment plant.    ADVANTAGE - The treatment plant: prevents ocean dumping and disposal of by-products; prevents lack of storage space, restriction of its usage as feed, and difficulty of handling the by-products throughout the year; produces dry pellets, which has low calorific value, and reduced water content of 10% thus can be used as renewable energy source, additives or feed and recovers high amount of heat; maintains the soluble substances e.g. pectin and fructose, energy and nutrients in the citrus fruit processed by-product; solves the problem of waste water containing high levels of contamination generated in the dehydration process, solves storage and decaying problems; meets the requirement of zero wastewater discharge; and ensures collection and composting of soluble solids.    DETAILED DESCRIPTION - Citrus fruit processing by-product zero discharge integrated treatment plant comprises a cutting machine (11) for cutting citrus fruit processing by-product (1), a crushing mill (12) for crushing the cut by-product, an initial processing device (10) comprising a raw material storage tank (13) for storing the milled citrus fruit processing by-product, a moisture control reservoir containing moisture control agent, a feed raw material reservoir for storing feed raw material powder, a mixer, which receives the raw material from the raw material storage tank, moisture control reservoir and feed raw material reservoir for mixing, a filtration device to filter out foreign substances from the mixed raw material, a first two-way ejector to selectively discharge the filtered raw material in both directions, a composting unit connected to one end of the first two-way ejector for manufacturing the compost by packing or composting mixed raw material in a breathable container, a pellet molding device connected to other end of the first two-way ejector to form the mixed raw materials into specific sized pellets, a dryer connected to the pellet molding device, a pellet storage tank for storing the dried pellets, a second two-way ejector to selectively discharge the dried pellets stored in the pellet storage tank in both the directions, a pellet mill connected to one end of the second two-way ejector to crush the dried pellet to obtain pulverized pellets, a dried pellet packaging machine connected to the other end of the second two-way ejector, and a fixed quantity measuring device connected to the raw material storage tank, moisture control reservoir and feed raw material reservoir to adjust the amount of raw material to be fed into the mixer. An INDEPENDENT CLAIM is also included for citrus fruit processing by-product zero discharge integrated treatment process, comprising cutting the citrus fruit processing by-product using a cutting machine, crushing the cut by-product by a crushing mill to less than 3 mm diameter, storing the pulverized by-product in a raw material storage tank, conveying the initially processed by-product into a moisture control reservoir containing a moisture control agent, mixing the feed raw material powder stored in the feed raw material reservoir into a mixer, filtering the mixed raw material via a filtration device, carrying out primary classification by conveying the filtered raw material into a first two-way ejector to selectively discharge into a composting unit at one end to obtain compost and a pellet molding device at the other end to mold the raw material into pellets of predetermined size, drying the pellets in a dryer, conveying the dried pellets in a pellet storage tank, carrying out secondary classification by passing the dried pellets through a second two-way ejector to selectively discharge into a pellet mill at one end for grinding the dried pellets, and a dry pellet packaging machine connected to the other end of the second two-way ejector for packing the milled pellets.
