The invention relates an extrusion device (100) for extruding a semi¬finished product made of elastomeric material, comprising an extrusion body (10) extending along a feeding direction (A) and a pump (20) arranged downstream of the extrusion body (10) along said feeding direction (A). The extrusion body (10) comprises a hopper (30) for loading an elastomeric material and an extrusion screw (50) extending along said feeding direction (A) and having an inlet portion (50a) arranged close to the hopper (30) and an exit portion (50b) arranged close to the pump (20). The extrusion body (10) also comprises a motorised roller (40) arranged at the inlet portion (50a) of the extrusion screw (50) and configured to receive the elastomeric material from the hopper (30) and feed it to the extrusion screw (30). The extrusion screw (50) has a length and a diameter such that the ratio between length and diameter is comprised between 4 mm and 8 mm. The invention also relates to an extrusion process carried out through the aforementioned extrusion device (100).

Metastable state spore incubation mixing systems are described. An example system includes a spores container to store spores, a nutrient container to store nutrients, a water supply line, a syringe tank, a syringe pump, an adjustable valve, a heater, and a controller. In a drawing phase of the system, a controller can cause the syringe pump and the adjustable valve to draw into the syringe tank a volume of spores, nutrients, and water to form a mixture. The controller causes the heater to heat the mixture for a period of time. In a dispensing phase of the system, the controller can cause the syringe pump to expel the mixture through the adjustable valve and into a water distribution system. The controller can direct the system through a number of other phases of operation.

Methods and systems are provided for mixing and heat exchange of fluids. In one example, a fluid mixing and heat exchange device includes a hot water tank, a mixing chamber spaced away from the hot water tank and fluidly coupled to a first liquid reservoir, a first chilling module fluidly coupled to the mixing chamber, a coolant tank fluidly coupled to the first chilling module, a radiator fluidly coupled to the coolant tank, and a dispensing manifold fluidly coupled to the mixing chamber and adapted to dispense a mixed and chilled fluid mixture to a plurality of fluid vessels.

Systems and methods have demonstrated the capability of rapidly cooling the contents of pods containing the ingredients for food and drinks.

A caffeine reduction apparatus includes: a main housing provided with an inlet and outlet pipe; a mixing portion including an accommodating portion through which coffee grounds are input inside the accommodating portion, and a blade configured to be rotated inside the accommodating portion such that the coffee grounds are mixed; a driving portion configured to rotate the blade; and an ultraviolet ray emitting portion positioned at an upper portion of the main housing and mounted at an inner side surface of a door that seals an inner portion of the mixing portion, the ultraviolet ray emitting portion being configured to emit ultraviolet rays toward the mixing portion.

A cooler includes a body made of an insulating material. The body includes a base and a sidewall upstanding from the base. The sidewall includes an upper rim defining an opening into the body. A lid releasably couples to the upper rim of the sidewall and covers the opening. A battery is coupled to the body. A mixer is coupled to an inner surface of the body and includes a motor electrically coupled to the battery. The mixer is configured to circulate water within the body when the motor is powered by the battery.

A mixing apparatus includes a housing that includes a first end wall, a second end wall, and a top wall that at least partially define a cavity of the housing. The apparatus also includes a pair of rollers extending from the first end wall to the second end wall and coupled to the housing such that each roller is rotatable relative to the housing. The apparatus also includes a motor positioned in the cavity and enclosed within the housing, the motor operatively coupled to a first roller of the pair of rollers and configured to drive the first roller to rotate for rotating the container. The motor is operatively coupleable to a power source to drive the first roller of the pair of rollers.

A mixing head 3 which mixes a first preparative liquid formulation containing a norbornene-based monomer with a second preparative liquid formulation containing a metathesis polymerization catalyst includes a casing 4, a cap 7, and a mixing rotor 6. A plurality of protrusions 622 includes first protrusions 622a having a width in the axial direction of the mixing rotor 6 larger than that in the circumferential direction, and second protrusions 622b having a width in the axial direction of the mixing rotor 6 smaller than that in the circumferential direction. First and second protrusion rows 623a and 623b are alternately arranged, the first protrusion rows 623a being formed of the first protrusions 622a aligned at a predetermined interval, the second protrusion rows 623b being formed of the second protrusions 622b aligned at a predetermined interval.

A blender system may include a base including a motor, a container, and a blade assembly. The blade assembly may include a gear drive. The gear drive may include an input and an output. The input may receive a drive shaft of a motor. The output may drive blades of a blade assembly. The gear drive may alter a rotational speed of the blades relative to a speed of the drive shaft of the motor.

An apparatus for accommodating a beverage includes an outer vessel defining a vessel cavity for receiving a cooling agent, a container having a lid and a beverage receptacle and a port. The lid is configured for engagement with the outer vessel to releasably mount the container to the outer vessel. The beverage receptacle defines a receptacle chamber for accommodating a liquid beverage for consumption by a user. The receptacle chamber is isolated from the vessel cavity. The beverage receptacle comprises a thermal conductive material and is at least partially disposed within the vessel cavity of the outer vessel when the container is mounted to the outer vessel whereby thermal energy is transferred from the cooling agent to the liquid beverage. The port defines a port opening in fluid communication with the receptacle chamber to permit distribution of the liquid beverage to the user. The outer vessel and mounted container may be positioned within a freezing apparatus to freeze the cooling agent, e.g., water about the beverage receptacle.
