A paper shredder cutting assembly having an arbor, spaced-apart cutting blades on the arbor, a rigid frame set apart from and parallel to the arbor, and braces coupling the arbor to the frame. Each resilient brace is a spacer between a pair of spaced-apart cutting blades. The braces support arbor and cutting blades. The rigid frame and the braces cooperate to strengthen, and to reduce translational motion of the arbor, while allowing rotation of the arbor. Each brace has a brace body, a brace tang extending therefrom, and a brace tab extending perpendicularly from the brace tang. Each brace tab is aligned with another along an edge of the rigid frame, the brace bodies are spacers between the cutting blades, and the brace tabs impair translational motion of the brace bodies. A paper shredder with a motor, gearing, and counterposing cutting assemblies has motion-limited resilient spacers adjacent to cutting blades.

A method and apparatus for infectious waste treatment. First, the infectious waste may be shredded into a mixture of liquid and shredded solid waste, then the mixture may be poured into a plurality of perforated bags. The liquid waste drips from the perforated bags onto a preheating subsystem and the solid waste remains in the perforated bags. The preheating subsystem heats up the liquid waste to a pre-disinfection temperature. Finally, steam may be utilized to heat up the liquid waste and the solid waste to a disinfecting temperature.

The fan device comprises a fan and a driving mechanism for powering the fan, and the fan is arranged in the steam container. The control PCB and the power supply PCB for controlling the heating temperature of the food are arranged in the base; the probe wire is connected to the power supply PCB; the food temperature probe is arranged on the output end of the probe wire; and the food temperature probe is located outside the steam container.

A rotary cutting machine, comprising a body base, wherein the body base is provided with a shredding and cutting component capable of rotating about the motor axis by 90?; and a power unit for powering the shredding cutter components. The power unit is connected to the shredding and cutting component, and the connector for connecting the power unit is provided on one side of the shredder tube, which comprises a shredder tube and a feed tube, wherein the feed tube is vertically arranged with the shredder tube. The shredder tube comprises a shredder tube shell. The strip cutter supporter is arranged in the shredder tube shell, the strip cutter is arranged on the side of the strip cutter support, and the spiral cutter support is clamped on the bottom surface of the strip cutter support, the spiral cutter is arranged on the spiral cutter support, the strip cutter and the spiral cutter are arranged perpendicular to each other. The rotary cutting machine integrates a strip cutter and a spiral cutter in a shredder tube shell, and integrates the two kinds of cuts with different output power modes to facilitate the conversion between the strip cutting and spiral cutting modes.

A food waste treatment apparatus is described. The apparatus includes a housing that defines a space that is configured to dehydrate and dry food waste, the housing having a drain pipe that is configured to discharge water included in the food waste and an exhaust duct that is configured to exhaust air that dried the food waste. The apparatus further includes a dryer that is configured to dry the food waste by supplying dry air to the housing. The apparatus further includes an exhaust unit connected to the drain pipe and the exhaust duct, the exhaust unit being configured to prevent the air exhausted from the exhaust duct from flowing back into the drain pipe.

A stationary housing (3) has an interior space (5) and at least one interior wall (7). At least one sawblade (9) is rotatable with respect to the stationary housing (3), and has a periphery (12) provided with a plurality of cutting teeth (15) and a plurality of collecting notches (17). An inlet opening (19) for feeding material to the interior space (5), and an outlet opening (21) for dispatching pulverized material from the interior space (5) are provided in the interior wall (7) of the housing (3), with a plurality of recesses (23) facing the periphery (12) of the sawblade (9) receiving the cut material from collecting notches (17) of the sawblade (9), and reverting the cut material to the periphery (12) of the sawblade (9) so that the material is cut multiple times before dispatch. The interior wall (7) surrounds a main part of the periphery (12) of the sawblade (9), and the inlet opening (19) and the outlet opening (21) are in direct communication with the interior space (5) so that the material enters and leaves the interior space (5) during one revolution of the sawblade (9).
