摘要:
A freeze dryer processes aseptic bulk powder products. The freeze dryer freezes the product by mixing an atomized spray of product with sterile liquid nitrogen to produce a frozen powder. The frozen powder is freeze dried in a vessel by dielectrically heating the frozen powder using electromagnetic radiation such as microwave radiation or infrared radiation, and the frozen powder is continuously agitated using a sterilizable apparatus such as a series of vibrating shelves to maintain even heating and to prevent agglomeration.

Extruded nutritional powders and methods of manufacturing the extruded nutritional powders, including extruded infant nutritional powders and extruded adult nutritional powders are provided. The processes utilize an extruder that is capable of internally mixing and emulsifying protein, and optionally, a carbohydrate with fat and water into an emulsion that can be dried into a powder having equivalent fat separation and dispersibility as compared to spray dried powders.
摘要:
A process for producing a freeze-dried product in a bonded or stratified state by a simple apparatus and by simple operations, without suffering from denaturation by oxygen, enzymes, heat and so on, while maintaining the original quality, properties and so on, by bonding or stratifying materials to be treated before being subjected to freeze-drying; an apparatus therefor; and a freeze-dried product obtained therefrom are provided. The freeze-dried product is obtained by stratifying materials 7a, 7b and 7c of the same or different kind to be treated into a multilayer under interposition of dry ice 6b, 6c partly in between the layers; pressing the multilayer from both sides by pressurizing elements 13 and 16 under intermediation by dry ice 6a and 6d to effect bonding of the materials to be treated with each other, while, at the same time, freezing the multilayer; and subjecting the frozen product to vacuum drying.
摘要:
A method for producing a block-shaped freeze-dried food product in a shorter drying time is provided, including filling a cooked liquid or paste food in a block-shaped cast tray with a recess part on the bottom, overlaying a metal plate on the bottom of the tray and placing the tray in between heating shelves in a drying chamber, or overlaying a metal plate with a protrusion part at a corresponding position so that the protrusion part can be inserted in and adhere to the recess part on the bottom of the tray and placing the tray in between heating shelves in a drying chamber.
摘要:
In a freeze-concentrating apparatus, an aqueous solution is cooled by a cooling cylinder 22 serving as a heat exchanger for cooling to continuously produce a suspension containing ice crystals. A liquid component is separated and discharged from the suspension to increase the ratio of the ice crystals, and the ice crystals are grown to produce a column-shaped ice cake. The ice cake is cut into an ice pillar of a given length and a concentrated solution is taken out from the ice pillar.
