The ingredients can supplement the nutrients such as carbohydrates and vitamin A that are missing in bone and meat residues to ensure that the pet feed is nutritionally balanced. The ingredients are preferably corn and vegetables, among which the vegetables are preferably carrots and sweet potatoes (sweet potatoes are rich in dietary fiber, which helps regulate the stomach and intestines of pets, and can also improve the immunity of pets; the vitamin A in carrots is very good for the pet's hair). A feed formula is provided, and the weight ratio is as follows: bone and meat residue after squeezing and defatting: corn: vegetables = 1:1:0.3. In this system, there is no need for additional bone and meat residue drying, crushing and cooling equipment, and the heat and moisture carried by the bone and meat residue can be efficiently utilized, saving equipment investment and production costs; the crushing mixer 5 integrates the functions of crushing, stirring, mixing, pushing / discharging, etc., and there is no need to separately crush and pre-treat materials such as corn, vegetables, bone and meat residue, which greatly simplifies the supporting equipment and facilities, occupies a small area, has a simple system, and significantly reduces equipment investment and operating costs.

[0071] Embodiment 3

[0072] Please refer to Figure 1-Figure 3 This embodiment describes a technical solution in combination with a slaughter waste resource utilization system and process. The technical solution describes the process and also introduces the equipment / devices involved in the process.

[0073] The crushed slaughter waste (mainly animal carcasses and internal organs) is processed by drying, and the waste gas generated after high-temperature and high-pressure sterilization is discharged into the feed drying section, and the waste gas heat is used to dry it, so as to achieve energy recovery and reduce operating costs. The high-temperature waste gas generated by the drying process in the sterilization kettle 8 is conventionally cooled and condensed, and then sent to the exhaust gas treatment device to achieve standard emissions. This technical solution does not need to cool the waste gas, and makes full use of the waste gas heat to heat and dry the feed, which not only achieves energy recovery and reduces operating costs, but also simplifies the equipment configuration of the exhaust gas treatment system (the cooling system needs to include a circulating water system, a condenser, etc.).

[0074] The (sterilized) material is sent to the press 7 for degreasing treatment, and the bone and meat residue produced therein does not need to be cooled or dried, but is directly sent to the crushing mixer 5 for further crushing; the oil and oil residue are further separated by centrifugation to obtain pure oil and fat, which is sent to the oil storage tank 10 for regular sale and utilization, and the oil residue is transported back to the crushing mixer 5 for reuse.

[0075] The ingredients (vegetables, corn, etc.) are accurately weighed according to the nutritional needs of the pet and added to the crushing mixer 5 for full crushing, stirring and mixing. The heat and moisture of the bone and meat residue itself (if the moisture and heat are insufficient, an auxiliary hot water mechanism is set to add hot water) are used to heat and gelatinize the vegetables and corn so that they are fully matured to ensure that the feed is easy to digest and at the same time ensure that the nutritional components of each portion of feed are balanced. In one example, the temperature of the bone and meat residue after squeezing and defatting is about 95°C and the moisture content is about 25%. It does not need to be cooled or dried, and is directly sent to the crushing mixer 5. The ingredients are added simultaneously for full crushing and mixing, and the heat and moisture carried by the bone and meat residue itself are used to heat and mature the ingredients.

[0076] After mixing and gelatinization, the materials are sent to the roller granulator for granulation, and then sent to the partition drum dryer for drying, and the moisture content of the pet feed is reduced to below 10%. The materials are transported to the cooling screen 1 through the screw conveyor, and the materials on the screen enter the finished product warehouse for measurement, packaging, and external sales; the materials under the screen are returned to the crushing mixer 5 for comprehensive utilization of material circulation. Among them, the partition drum dryer uses the high-temperature steam generated by the dry process as a heat source to dry the feed; the high-temperature exhaust gas generated by the dry process (sterilizer 8) is fully utilized as a drying heat source to achieve energy recovery and reduce operating costs; the condensed water in the exhaust gas enters the sedimentation tank and other sewage treatment systems for treatment.

[0077] The slaughter waste resource utilization system and process fully utilizes the high-quality protein and fat and other nutrients in the slaughter waste, which not only solves the problem of harmless treatment and disposal of slaughter waste, but also improves its resource utilization, achieving both economic and social benefits. Among them, the heat and moisture carried by the bone and meat residue are used for mixing, heating and maturation of the ingredients, which can not only improve the digestibility of the feed, but also achieve energy recovery and utilization and reduce operating costs; the high-temperature exhaust gas heat generated by the dry process is used to heat and dry the feed, realizing the recovery of exhaust gas heat, while simplifying the configuration of the exhaust gas treatment system equipment and reducing investment and operating costs.
