A device for preparing a gelatin-based product may include a mix tank, a mix pod that is fluidly coupled to the mix tank via a pod spike, and a hot water tank, where the hot water tank is coupled to the mix pod via the pod spike. In at least one example, the pod spike may include an outer tube and an inner tube. In one or more examples, the pod spike of the device may include a hub, where a first end of the outer tube is coupled to the hub. Further, in some examples, a first end of the inner tube may also be coupled to the hub.

A system includes a recirculation line, a mainline flow meter operable to measure a flowrate of fluid flowing through the recirculation line, a mixing chamber, an inlet line coupled between the recirculation line and the mixing chamber, at least one chemical injection port coupled to the inlet line, a dedicated feed pump operably associated with each chemical injection port, and an outlet line coupled between the mixing chamber and the recirculation line. The mixing chamber includes a plurality of mixing zones, a mixing blade assembly that includes at least one blade within each mixing zone, and a motor coupled to the mixing blade assembly and operable to rotate the mixing blade assembly. Each of the dedicated feed pumps is coupled to a separate chemical supply and is operable to pump a chemical to the corresponding chemical injection port for injection into the inlet line.

A system for dispensing a plant-based milk includes a mixing chamber for emulsifying a plant-based paste and water, a plant-based paste storage connected to the mixing chamber via a first conduit, a water storage connected to the mixing chamber via a second conduit, and a cooling system. The system includes a pumping system for moving a prescribed amount of the plant-based paste into the mixing chamber upon receiving an input from a user via a user interface, a flow system for flowing water from the water storage to the mixing chamber, and a control system. The control system receives the input from the user, activates the pumping system and activates the flow system. Further, the control system activates the mixing chamber for emulsifying the plant-based paste and the water, and dispenses the emulsified plant-based mixture of the paste and the water.

A cell culture device (1) includes: a culture vessel (10 ) that accommodates a cell suspension containing cells and a culture medium; and a stirring device (30) that is provided at a bottom part of the culture vessel (10) to stir the cell suspension accommodated in the culture vessel (10). The stirring device (30) has a shaft part (32), and a rotating part (33) rotatable with the shaft part (32) as a rotation axis. The rotating part (33) has a hole part (36) into which the shaft part (32) is inserted, and a gap (37) of 100 μm or more is secured between an interior wall demarcating the hole part (36) and the shaft part (32). A closing part (38) that closes an end part of the gap (37) in an axial direction of the rotation axis is provided.
