The outlet is in communication with the buffer chamber, and the buffer chamber is positioned between the first and second valves. The buffer chamber of the first dispensing unit defines a first chamber volume, and the buffer chamber of the second dispensing unit defines a second chamber volume greater than the first chamber volume.

A particle-carrying feedstock is mixed by a rotor-stator mixing mechanism placed within a mixing chamber where mixing is conducted under a negative pressure for separating and removing entrained air from the mixed feedstock, preferably before passing the de-aerated mixed feedstock to a media mill for processing into a particle dispersion. The rotor of the rotor-stator mixing mechanism preferably includes a disk carrying vanes on opposite faces of the disk for a conducting simultaneous dual mixing operations. Openings in the stator are provided with an H-shaped cross-sectional configuration and are intermingled for facilitating the mixing operation while maintaining the integrity of the rotor-stator mixing mechanism.

A food material powder supply device 1 of the disclosure includes a supply tank 50 that temporarily stores food material powder in a tank 50A and supplies the food material powder to a processing container 2A of a food processing machine 2, a vacuum device 70 that reduces the pressure inside the supply tank 50 with vacuum pumps 71A and 71B, and a control device 3 that operates the vacuum device 70 to reduce the internal pressure of the supply tank 50 to be equal to or lower than a predetermined atmospheric pressure at which moisture of the food material powder is evaporated and cools the food material powder in the supply tank 50. A stirring member 54 which is driven to rotate during the cooling of the food material powder is arranged inside the tank 50A.

The objective of the present invention is to provide a storage container for a vacuum blender having a backflow prevention function, which is configured such that a floating valve member is installed at a lower part of a sealing lid for covering the storage container for the vacuum blender, and when micronized foodstuffs, such as foam, rise in the process of creating a vacuum in the storage container, the floating valve member rises together by means of buoyancy of the micronized foodstuffs to hermetically seal an air passage, thereby preventing the micronized foodstuffs from flowing back out of the storage container. In order to achieve the above objective, the storage container for a vacuum blender having a backflow prevention function, according to the present invention, is a storage container used in a vacuum blender capable of processing foodstuffs in a vacuum state, and comprises: a container body which has an open upper portion and is provided with an inner space for storing foodstuffs; a sealing lid which covers the upper portion of the container body and has a check valve for blocking air from flowing into the inner space from the outside of the container body in a vacuum state; and a backflow preventing means which is installed at a lower portion of the sealing lid and has a floating valve member embedded therein to prevent micronized foodstuffs from flowing back out of the sealing lid through the check valve in such a manner that when the micronized foodstuffs rise, the floating valve member rises together by means of buoyancy to hermetically seal an air passage.

In some embodiments, a method of making hydrated bone material is provided, the method comprising providing a bone material in a chamber, the bone material comprising a plurality of shaped bone particles or macroparticles, each of the plurality of shaped bone particles or macroparticles having a substantially uniform size, shape and porosity; and mixing each of the plurality of shaped bone particles with liquid in the chamber under pressure so as to cause the liquid to hydrate each of the plurality of shaped bone particles to form uniformly hydrated bone material. In some embodiments, a device for mixing a bone material with a liquid is provided.

A reactor for coating particles includes a stationary vacuum chamber having a lower portion that forms a half-cylinder and an upper portion to hold a bed of particles to be coated, a vacuum port in the upper portion of the chamber, a paddle assembly, a motor to rotate a drive shaft of the paddle assembly, a chemical delivery system to deliver a first fluid, and a first gas injection assembly to receive the first fluid from the chemical delivery system and having apertures configured to inject a first reactant or precursor gas into the lower portion of the chamber and such that the first reactant or precursor gas flows substantially tangent to a curved inner surface of the half-cylinder.

A method of coating particles includes dispensing particles into a vacuum chamber to form a particle bed in at least a lower portion of the chamber that forms a half-cylinder, evacuating the chamber through a vacuum port in an upper portion of the chamber, rotating a paddle assembly such that a plurality of paddles orbit a drive shaft to stir the particles in the particle bed, injecting a reactant or precursor gas through a plurality of channels into the lower portion of the chamber as the paddle assembly rotates to coat the particles, and injecting the reactant or precursor gas or a purge gas through the plurality of channels at a sufficiently high velocity such that the reactant or precursor a purge gas de-agglomerates particles in the particle bed.

A mixer is disclosed including a sealed mixing chamber having an interior, and a rotating mixing bowl within the interior of the sealed mixing chamber. A stand operatively supports the sealed mixing chamber. The stand includes: a foundation, a mixing chamber base movably coupled to the foundation and positioning the sealed mixing chamber at an angle relative to horizontal, and a linear actuator system configured to move the mixing chamber base relative to the foundation in at least one linear direction. A rotating mixing head is operatively positioned and sealingly disposed within the sealed mixing chamber, the rotating mixing head rotating within the rotating mixing bowl.
