A machine prepares semi frozen food products and / or beverages from pre-prepared (e.g. frozen) cups. A user chooses the desired frozen cup, inserts it into the machine, chooses how they would like it prepared from a range of thickness options, and the machine then opens a sealed chamber door and inserts the product upward into the chamber and prepares the product by blending it in the cup. Upon removal of the product and resealing of the chamber door, the cleaning mechanisms provide thorough cleaning of all food contact surfaces and the chamber interior. Automatic high temperature steam sanitation takes place in the chamber if the machine is not used for an extended period of time, thus greatly reducing or eliminating the need for manual cleansing and sanitation by an attendant and ensuring healthy food preparation at all times.

An electro thermal fluidized bed furnace is adapted to be used in a process for continuously heat treating of fine particulate matter, such as carbon black material, by continuously introducing a non-reactive fluidizing gas through the nozzles of the furnace at a pre-determined rate, continuously introducing untreated carbon black material through the feed pipe of the furnace at a predetermined rate so that it forms a fluidized bed, energizing the electrode so as to heat the fluidized bed, and continuously collecting the treated carbon black from the discharge pipe. The carbon black collected from the discharge pipe exhibits properties of having the PAHs and sulfur removed, the carbon black has been graphitized, the moisture pick-up by the carbon black has been eliminated and the carbon black is more oxidation resistant, Furthermore, the resultant furnace carbon backs have a particle size of 7-100 nm and an oil absorption number of 50-300 ml / 100 g., while the thermal blacks have a particle size of 200-500 nm and an oil absorption number of less than 50 ml / 100 g. All of these properties result in thermally modified carbon blacks having such properties and of such purity so as to provide improved performance properties in food contact type applications, moisture cured polymer systems, zinc-carbon dry cell battery applications, and semi-conductive wire and cable applications.

The incorporation of nanosized metal particles into cyclodextrin-containing material leads to a “reactive” barrier material having excellent barrier properties. Also, it has been found that the presence of nanosized metal or metal alloy particles in a barrier material such as thermoplastic material, wherein said material comprises cyclodextrin derivatives, may be advantageous in achieving excellent barrier properties. The barrier material of the present invention may provide improved barrier resistance to a variety of permeants and / or impurities. The diffusion of volatile substances through the barrier material may be prevented by adding compatible derivatized cyclodextrin and nanosized metal particles to the material used. Accordingly, the inventive material also is suitable for many applications including food-contact packaging, flexible packaging to dispose of adult and baby diapers, incontinent products, hospital and household waste and also for packaging pharmaceutical products, medical devices and dental materials.
