A solenoid valve includes a main valve, a first auxiliary valve, a second auxiliary valve, a main valve body, and an auxiliary valve body. The main and auxiliary valve bodies are axially parallel and detachably connected. The main valve is mounted on the main valve body, the first and second auxiliary valves are mounted on the auxiliary valve body, which is provided with an air inlet, a cylinder port and an air discharging port. The air inlet communicates with the main valve through a first air passage. The cylinder port is sequentially in communication with the first and second auxiliary valves and the main valve through a second air passage. The air discharging port sequentially communicates with the first and second auxiliary valves and the main valve through a third air passage. The main and second auxiliary valves are solenoid valves. The first auxiliary valve is a hand-operated valve.

A system and method for a process to prepare consumable food and/or drink products by means of precise heating and stirring for a set period of time. The system utilizes a variable rotation rate magnetic stirring process, a variable temperature heating process, and a timing process in order to prepare consumables. The magnetic stirrer provides agitation to a fluid medium and facilitates homogenous distribution of heat produced by the heating element throughout the fluid. This even distribution of heat creates an improved consumable preparation. The system is suitable for home use.

An improved a device and method for dispersion and simultaneous orientation of nanoparticles within a matrix is provided. A mixer having a shaft and a stator is provided. The shaft may have a rupture region and erosion region. Further, an orienter having an angled stationary plate and a moving plate are provided. The nanoparticles and the matrix are fed into the mixer. A rotational force is applied to the shaft to produce shearing forces. The shearing forces disperse and exfoliate the nanoparticles within the matrix. The dispersed mixture is outputted onto the moving plate. The moving plate is forced across the angled stationary plate to produce fully developed laminar shear flow. The fully developed laminar shear flow or the two-dimensional extensional drag flow orients the dispersed nanoparticles-matrix mixture.

Systems and methods of producing a frozen food product include dosing ingredients with a liquefied gas while mixing the ingredients using self-cleaning interlocking beaters. The beaters are optionally also disposed to clean a container in which the ingredients are frozen. The rate and amount of cooling is controlled by measuring the quantity of liquid nitrogen, measuring viscosity of the frozen food product, measuring temperature, and/or the like.
