The present disclosure provides a compact and automated single device capable of washing, drying, and sterilizing a bottle and its accessories, along with preparing and filing milk in the cleaned bottle. The device receives the bottle and the accessories in two separate towers, and wash them properly by creating a whirl of heated water inside and around the bottle and accessories. Further, the device dries the washed bottle and accessories with clean and filtered heated air to prevent contamination of the bottle and accessories during drying. UV lights are also provided inside the two towers to completely sterilize the dried bottle and accessories to kill any microorganism present on their surface. The device further includes an inbuilt milk dispenser to prepare and dispense milk in the cleaned bottle. The device is remotely operable as well as monitorable by users using mobile devices.

A multi-axis variable-speed hot washing module and a hot washing method thereof are provided. The multi-axis variable-speed hot washing module includes a storage assembly, a dehydration assembly, and one or more multi-axis variable-speed hot washing machines, where the multi-axis variable-speed hot washing machine is connected to the storage assembly and the dehydration assembly. Batches of materials are stored in the storage assembly. When cleaning, the materials are put from the storage assembly into one or more multi-axis variable-speed hot washing machines, and medicinal water is added. The multi-axis variable-speed hot washing machine replaces functions of a hot washing machine, a screw, and a friction machine, and has relatively large mechanical friction on the materials during cleaning. The materials after being hot washed by the multi-axis variable-speed hot washing machine are transported to the dehydration assembly for dehydration, so as to implement separation of cleaning water and the materials.

The invention is generally a system for drying, recycling, and washing off residual resin from three-dimensionally (3D) printed objects. Exemplary systems may include a system for washing off residual printing material from a surface of a 3D-printed. In an exemplary embodiment, a chamber is adapted to receive the 3D-printed object and a printing material disruption module is adapted to disrupt a composition of residual printing material on a surface of the 3D-printed object. Additionally, a washing force module may be adapted to apply a washing force field to the 3D-printed object and wash off the residual printing material.
