The present invention is directed towards a process for upgrading lignite comprising: prior to production pre-assess the calorific value of the coal, by selecting a relational expression between a calorific value of lignite and a degree of metamorphism, a moisture content and an ash content thereof based on a ratio of the ash content to the moisture content, pre-assess the calorific value of the coal; combining a relational expression between a production cost and the ash content and moisture content to make a cost budget; determining degrees of deashing and drying; selecting and implementing a lignite ash reduction pretreatment process; and implementing dry sorting first and then drying. The upgrading process has high sorting efficiency, high drying efficiency and low production cost, and meets the requirement for the surface moisture of the raw coal in the dry sorting operation.

The present invention aims to provide a method and an apparatus for producing a lyophilized body, each of which can achieve energy saving, low cost, and a reduction in processing time and can provide a lyophilized body less damaged by a freezing process and a drying process. The present invention relates to a method for lyophilizing a substance using an electromagnetic wave, and the lyophilization method includes freezing the substance under irradiation of at least an electromagnetic wave and reduced-pressure drying the frozen substance under irradiation of at least an electromagnetic wave.

The present application encompasses methods and apparatus for heating a load such as clothes immersed in a medium such as water during a heating period. A method embodiment of the present invention comprises heating the load and medium within an enclosure by subjecting said load and medium to heated air originated from a conventional energy source; and applying heat to said load and medium within the enclosure via an AC electrical field, embodied as a capacitor, originated from an RF power source.

A nail lamp is configured to cure light-curable nail product on a user's nails. The lamp includes an array of discrete light sources with different light wavelength profiles. The different wavelength profiles are configured to, in combination, cure a light-curable nail product. A space is disposed beneath the array and is sized to accommodate therein the nails of an appendage of a user so as to expose the user's nails to light from the array. The space is substantially open to the ambient environment to the front, rear, left, right, and top of the space, thereby providing an open architecture.
