A continuous extrusion kneader comprising a first supply section for supplying a solid electrolyte, a first kneading section for kneading a material supplied from the first supply section to provide an intermediate mixture, a second supply section for supplying an electrode active material to the intermediate mixture, and a second kneading section for kneading the intermediate mixture and the material supplied from the second supply section, wherein the first kneading section comprises a forward kneading section for kneading the material supplied from the first supply section and conveying the material downstream, and a reverse kneading section for kneading the material supplied from the forward kneading section and applying a force in the upstream direction.

A self-cleaning extruding apparatus with two co-rotating screws and the method thereof are provided here. Said apparatus is comprised of a screw mechanism, a barrel (1), a feeding port (10), a venting port (11), and a discharge port (12). Said screw mechanism is comprised of the first screw with one tip (3) and the second screw with two tips (4). There is a baffle in the channel of the first screw and the baffle's height is lower than that of the screw flight. The baffle will cause hyperbolic perturbation in the shape of a ‘figure 8’ flow pattern above the top of the baffle. The first and second screws rotate at the same speed and touch each other at all times, thereby achieving a self-cleaning function.

The baffle will generate chaotic mixing in the screw channel caused by the hyperbolic perturbation. Topological chaos is also introduced into the screw channel by the mechanism ‘one part divided into two parts, then two parts converging into one part, and then one part divided into two parts once more’. Each of the screws in the present invention uses an asymmetrical flow channel geometrical shape, such that a periodic action like ‘compression—expansion—further compression—expansion further’ works. The above three enhancement mechanisms work together to efficiently accelerate melting and mixing.

A litter processing system is provided implementing one or more robotic vehicles to process livestock litter, detect conditions of the litter with a plurality of sensors, and treat the litter based upon data collected by the sensors. The vehicles may include processors and software that control vehicle tasks. The vehicle's onboard software may be controlled by a server having an instance of the software thereby controlling operation of the vehicles and collecting sensor data from the vehicles via a wireless network.

Apparatus for processing kitchen waste is disclosed. In some embodiments, the apparatus comprises an inlet for receiving the kitchen waste, a comminuter to comminute the received waste, a dewatering device to dewater the comminuted waste, a compressor to compress the dewatered comminuted waste, and an outlet to provide processed waste ready for collection, wherein the inlet has a lid moveable between a closed position and an open position and the inlet communicates with a hopper having an outlet, the hopper outlet communicating with the comminuter by a door mechanism, and wherein the door mechanism and the lid are interlocked such that the door mechanism opens to supply food waste to the comminuter only when the lid is in the closed position and such that the lid is openable to allow a user to add food waste into the hopper only when the door mechanism is closed.
