摘要:
A process for the production of an edible food supplement preservative from a rootcrop by processing such rootcrop into dry powder, the process steps including, placing the rootcrop in a closable vessel, subjecting the rootcrop to chopping or cutting while the vessel is evacuated, effecting a primary drying followed by the injection of an inert gas thereinto, crushing the rootcrop, spraying a synergist onto the crushed mass, spraying a drying distillation liquid thereonto, effecting a secondary drying of the resulting mass and mixing the dried mass to a dispersed state.

A controlled freezing-point dried food accompanied with its original freshness and having an excellent restoration ability to its original state is obtained by treating a fresh food in the presence of a freezing-point depression agent at a temperature of 0.degree. C. to a temperature in the range of the freezing-point controlled temperatures for prolonged period of hours without it being frozen thereby to make the food accompanied with cold-resistance, to maintain its original freshness and to improve its flavor and tastes and blowing chilled air of minus 5.degree. C. to 10.degree. C. with a stream rate of 0.5 m/sec. to 5 m/sec. onto the food for 5 to 600 hours.
摘要:
A hydration drying process is described for producing an improved free-flowing, non-hygroscopic food and/or beverage powder. The process involves the admixing of a juice concentrate with a predetermined amount of anhydrous dextrose in an agitating device until the desired degree of dryness is achieved. If desired, the rate of hydration of the dextrose molecules can be expedited by subjecting the mixture to a hydration enhancing step at a low temperature either during or after agitation of the mixture. When compared to conventional drying processes, the present invention is more economical, retains desirable volatiles, and develops negligible off-flavors during processing.
摘要:
A process for dewartering solid matter containing bound or unbound water comprises mixing the solid matter with an amount of a composition having an inverse critical solution point in a twophase system with water. The amount of the composition used must be sufficient for substantially all of the bound or unbound water in the solid matter to be completely miscible in a single phase in the composition at or below a first predetermined temperature. The temperature of the mixture is then adjusted to or below the predetermined temperature. The mixture is then mechanically separated, as by filtering, into a solid fraction containing the solid matter and a liquid fraction containing the composition and substantially all of the water. The liquid fraction is separated into water and the composition by raising the temperature of the liquid fraction to above the determined temperature, at which temperature the liquid fraction separates into two liquid phases. The composition phase is then decanted from the water phase, after which the composition phase can be recycled for dewatering additional solid matter. The preferred compositions are those secondary or tertiary amines, preferably aliphatic, which exhibit an inverse critical solution point in a two-phase system with water. Mixtures of these amines can be used. Most preferred of these secondary and tertiary amines are those having the formula
wherein, R1 can be hydrogen or alkyl, R2 and R3 can be alkyl radicals having one to six carbon atoms or alkenyl radicals having two to six carbon atoms, the total number of carbon atoms in the amine molecule being in the range of from three to seven, inclusive. An exemplary and preferred amine of this class is triethylamine. The solid matter to which this method is applicable includes a wide variety of materials including fecal matter (poultry feces and treated sewage sludge), other sludges (flocculant metal processing wastes), animal protein (egg white, whole eggs, whole fish, fish wastes, shellfish and shrimp wastes, and whole milk), and plant protein (spent brewer''s yeast, and green plants).
