A device and to a process which can be carried out using the device, for the production of fine particles from a liquid which solidifies upon cooling, in particular from liquid fat. The process has the advantage of producing fine particles of very small size, preferably with narrow size distribution. The device has the advantage that a solidifying liquid can be supplied at a temperature above its solidification temperature, without cooling gas leading to solidification of the liquid in the supply line, which cooling gas is used in the production of the particles.

Various embodiments disclosed relate to a method of cold-spray deposition involving cooling the cold-spray nozzle by at least one of expanding and vaporizing a compressed cooling fluid in proximity to the cold-spray nozzle. The present disclosure also includes a cold-spray deposition spray head, a cooling jacket for a cold-spray deposition nozzle and a cold-spray deposition system comprising the same.

The present invention relates to self-foaming hot melt adhesive compositions and methods of making and using the same. Self-foaming hot melt adhesive compositions are formed by admixing a dispersion concentrate including a chemical blowing agent and a compatible carrier (liquid or molten) with a molten base hot melt adhesive composition at a temperature below the decomposition temperature of the chemical blowing agent. The resolidified material is processed through a device that heats the material above the decomposition temperature of the chemical agent and cools it below such temperature before being dispensed. The device preferably includes sensors and a controller configured to prevent the material from accumulating an adverse thermal history during processing.

The invention relates to an inhaler component for forming a vapor-air mixture and/or condensation aerosol by vaporizing a liquid material and optionally condensing the vapor formed, including: a heating element for vaporizing a portion of the liquid material; a wick for automatically supplying the liquid material to the heating element, wherein the wick comprises at least two end sections arranged apart from each other; a first capillary gap for automatically supplying the liquid material to the wick, wherein a first end section of the wick projects into the first capillary gap. In order that the heating element can be supplied more quickly and ore reliably with the liquid material, a second capillary gap is provided, which receives therein the second end section of the wick.

An atomizing device for a steaming face instrument, which comprises: a water delivery channel, the water delivery channel includes a water inlet and a water outlet; an atomizing sheet, the atomizing sheet is arranged at the water outlet , for atomizing water; and a heating mechanism, the heating mechanism is connected to the water outlet for heating the water mist, so that the temperature of the water mist is controlled between 45 and 60 degrees. By adopting the above design, the disclosure enables the liquid water to be atomized by the high-frequency resonance of the atomizing sheet, and then heats the water mist, so that the temperature of the water mist is controlled at 45-60 degrees, which is safe and effective. The volume of the face steaming instrument is reduced, it is convenient to carry, its power consumption is small, energy saving and environmental protection.

A thermal fogger includes an air-supply system and a chemical injector. The air-supply system includes an air chamber, a pre-heater configured to heat air in the air chamber, and a blower in fluid communication with the air chamber and configured to blow a flow of heated air through an outlet of the air chamber. The chemical injector is coupled to the outlet of the air chamber and is configured to inject a liquid chemical into the flow of heated air to produce an air-chemical mixture.

A shisha device comprises a cooling element (13) disposed along an airflow channel to cool an aerosol. The cooling re) element unit utilizes active cooling and may additionally utilize passive cooling. The cooling element may comprise a conduit (21) comprising a thermally conductive material. The cooling element may be integrally formed with an accelerating element (14) disposed along the airflow channel. Cooling may occur before or during acceleration of the aerosol by the accelerating element. The cooling may contribute to the condensation in the aerosol.

A method of printing a three dimensional article (201) can include forming a bottom layer of the three dimensional article (201) by spraying a dry build material powder (210) onto a build platform (230) while heating the dry build material powder (210). The dry build material powder (210) can include metal or ceramic particles mixed with a polymeric binder having a softening point temperature. The dry build material powder (210) can be heated to a temperature above the softening point temperature such that the dry build material powder (210) adheres to the build platform (230). Subsequent layers can be formed by spraying dry build material powder (210) onto a lower layer while heating the dry build material powder (210) such that the dry build material powder (210) adheres to the lower layer.
