The disclosure relates to systems and methods for improving the manufacturing of silk solutions and powders containing silk fibroin obtained from silkworm cocoons. The methods include use of a reactor vessel to degum, rinse, and dissolve the silk fibroin protein from silk inputs to obtain a food grade silk powder. The reactor vessel may include a combination of inputs and outputs for introducing and removing different components used or generated during the process. The systems may include any combination of heat exchangers, holding tanks, filtration modules, and post-treatment equipment as necessary to obtain the silk powder. The solutions and powders can be used to improve the post-harvest preservation of perishables and to improve the performance of packaging, including biodegradable packaging.

An assembly and a method for treating raw water wherein the raw water is heated on the heating side of a heat pump and at least partially evaporated into an air stream. At least part of the raw water evaporated into the air stream is separated in a suitable device. In addition, the heat pump is provided with heat on the cooling side by means of heated raw water that has not been evaporated into the air stream, and the heat pump has a thermal coupling in a coldest section of its cooling side, in order to provide cooling for external applications.

A cryogenic distillation tower for separating a feed stream. The tower includes a distillation section. A controlled freeze zone section is situated above the distillation section and forms a solid from the feed stream. The controlled freeze zone section includes a spray assembly in an upper section and a melt tray assembly in a lower section. The melt tray assembly includes at least one vapor stream riser that directs the vapor from the distillation section into liquid retained by the melt tray assembly, and one or more draw-off openings positioned to permit a portion of the liquid to exit the controlled freeze zone section. The portion of the liquid indirectly exchanges heat with a heating fluid. One or more return inlets return the portion of the liquid to the melt tray assembly after it has been heated in the heat exchanger.

The present invention generally relates to a system for treating effluent water. More particularly, it provides a robust apparatus for treating waste liquid by optimizing solar and wind energy to maximize the evaporation rate as compare to natural evaporation rate. The main object of the present invention is to provide a system for evaporating RO reject and other effluent liquid and other liquids, by optimizing system to solar and wind energy to maximize vaporization rate and recovery rate at marginal operational cost.
