A dehydration filter cartridge 7.2 is rotatably arranged inside the dehydration chamber 7.1. The ground food waste enters the dehydration filter cartridge 7.2 through the feed port on the dehydration chamber 7.1. A dehydration extrusion rod 7.3 is arranged inside the dehydration filter cartridge 7.2. The dehydration extrusion rod 7.3 is a variable diameter and variable pitch spiral rod, and a brush is installed along the spiral blade. The brush contacts the inner wall of the dehydration filter cartridge 7.2. The food waste entering the dehydration filter cartridge 7.2 is transported upward by the dehydration extrusion rod 7.3 through the spiral blade. The variable diameter and variable pitch structure makes the gap between the dehydration extrusion rod 7.3 and the dehydration filter cartridge 7.2 continuously narrow. As the gap continuously narrows, the food waste is removed. The brush installed on the blade continuously cleans the filter holes on the side wall of the dehydration filter cartridge 7.2 during the rotation of the dehydration extrusion rod 7.3 to ensure that the filter holes are unobstructed, and the liquid is squeezed into the gap between the dehydration filter cartridge 7.2 and the dehydration chamber 7.1. A drain pipe 7.4 is provided at the bottom of the dehydration chamber 7.1, and the liquid is discharged through the drain pipe 7.4. The side wall of the dehydration chamber 7.1 is provided with a slag outlet 7.7 and a third nozzle 7.8. After the solid kitchen waste is dehydrated, it is transported to the slag outlet 7.7. The third nozzle 7.8 is connected to an external water source, and water enters the third nozzle 7.8 from the third nozzle 7.8. Directly discharged to the garbage can 9, the dehydration extrusion rod 7.3 is powered by the motor through the synchronous belt transmission mechanism 7.5, and is bolted to the third mounting seat 7.9, and the third mounting seat 7.9 is prevented from being on the frame 10 and bolted.

[0044] The outer shell sheet metal 3 is made of 304 stainless steel. The upper opening of the grinder is equipped with a transparent observation window, which can directly check the working condition of the grinder and check whether there are foreign objects entering the grinder in case of accidents. There are five inspection doors on the side, each with a cabinet door lock, and an inspection door on the top with a proximity switch, so that the equipment cannot run when the inspection door is open, which increases safety.

[0045] The equipment adopts an intelligent electric control system, and the electrical components are placed in the electric control cabinet 8. It is equipped with a running, reversing and cleaning lighted button and an emergency stop knob, a power indicator light and a buzzer. Turn on the power, release the emergency stop button, the power indicator light comes on, press the run button, the No. 1 electric ball valve opens, so that the second nozzle 6.6 and the first nozzle 4.5 are connected to the water source, the dehydrator 7, the grinder 6 screw conveyor 5, the crusher 4, and the filter conveyor 1.1 start to run in sequence, the default running time is five minutes and can be adjusted). During the operation, press the run button again and the equipment stops running; press and hold the reverse button, the crusher motor reverses, and releases it to stop rotating; press the cleaning button, the No. 1 and No. 2 electric ball valves open, and the third nozzle 7.8, The second nozzle 6.6 and the first nozzle 4.5 are connected to the water source, and the dehydrator 7, the grinder 6 screw conveyor 5, the crusher 4, and the filter conveyor 1.1 start to run in sequence. The default running time is two minutes and can be adjusted. During the operation, the cleaning button is pressed again and the equipment stops cleaning. When the equipment is not in use, the emergency stop button is pressed and the power indicator light goes out. When the buzzer detects a signal from the liquid level switch 1.5 in the grease separator 1, the operator is alerted to the need to collect and discharge grease and water. The system is equipped with overload protection to prevent the motor from burning out due to unexpected situations.

[0046] Pour the food waste into the 1.1 filter conveyor, separate the grease and water into the 2 grease separator through the filter, and convey the preliminarily filtered food waste to the 3 grinder through the 1 filter conveyor for crushing. The 3 grinder performs coarse crushing on the food waste, and can also crush hard food waste including large bones. After crushing, it is uniformly conveyed to the 5 grinder through the 4 spiral conveyor, and the 5 grinder will further grind the food waste into particles of appropriate size. The 5 grinder has a built-in water spray head to increase the fluidity of the ground food waste. The special structure of the grinding blade will generate negative pressure under high-speed rotation, and the food waste will be pumped to the 6 dehydrator, which dehydrates the food waste by extrusion and discharges the dehydrated food waste into the 7 garbage can.

[0047] Firstly, this invention collects and separates grease from kitchen waste to prevent it from being directly discharged into the pipes and causing pipe blockages. Secondly, it can handle large and hard kitchen waste such as bones that are inevitable in Chinese food. Thirdly, its small size can be used in the kitchen to directly handle kitchen waste, meeting the requirements of on-site treatment. Fourthly, the dehydration rate is ≥70%, and the reduction in operating costs and waste disposal costs is directly visible.
