A method for obtaining an olive oil in situ, which comprises the operation of packaging and preserving a dry olive preparation formed from an olive paste that is firstly frozen and then freeze-dried in a capsule, preferably a single-dose capsule; and the operation of reconstituting the olive paste by hydrating it inside the capsule to obtain an olive oil that will be extracted from the capsule by pressure. The capsule comprises a filtering membrane having micro-perforations suitable for retaining the preparation and the passage of traces of olive wastewater or water particles therethrough, which may contain an olive oil obtainable from rehydrating the olive paste inside the receptacle and a machine for cooperating with the capsule comprising an injection head of a liquid and a piston prepared for pressing the preparation and subjecting it to a pressure greater than 10 bar.

[Object] To freeze droplets of a raw material liquid in a shorter drop distance while maintaining a cooling velocity, which is a super high speed, without deteriorating a solute or dispersoid.

[Solving Means] A vacuum freeze-drying method according to an embodiment of the present invention is a vacuum freeze-drying method that includes steps of injecting a raw material liquid from an injection nozzle inside a vacuum chamber, generating frozen particles by self-freezing of the raw material liquid, and drying the generated frozen particles to thereby produce a dry powder, including: injecting the raw material liquid from the injection nozzle in a state in which the vacuum chamber is maintained at water vapor partial pressure corresponding to a self-freezing temperature of the raw material liquid, such that an injection initial velocity of the raw material liquid from the injection nozzle is 6 m/s or more and 33 m/s or less; and adjusting, when the maximum diameter of the generated frozen particle exceeds a predetermined value or droplets of the raw material liquid are unfrozen, an injection flow rate of the raw material liquid from the injection nozzle or properties of the injection nozzle such that frozen particles having a maximum diameter equal to or smaller than the predetermined value are generated.

A composition is manufactured from a freeze-dried mixture comprising one or more freeze-dried embryonic sprouted plants and one or more flavorings, such as a fruit, vegetable, or other natural or artificial flavoring. In some embodiments, the composition is molded into desired shapes and packaged. In other embodiments, the composition is not molded but pulverized into powder for reconstitution. The composition is manufactured by controlling the dry heat added, controlling the growth cycle of the embryonic sprouted plants, and including a step of freeze-drying the mixture. The food is intended to be consumed by human being or lower animals in whole or part via the oral cavity.

A technology for protecting a valve seat inside a collection tank from the adherence of frozen particles in a vacuum freeze-drying apparatus and a frozen particle manufacturing method. The inside of a vacuum tank and a collection tank are vacuum evacuated; a raw material liquid is injected into the vacuum tank to produce frozen particles; and the frozen particles are piled up on a surface of a heating/cooling shelf. When the frozen particles on the heating/cooling shelf are transferred into the collection tank through the inside of an auxiliary pipe, the frozen particles do not adhere to a valve seat which surrounds an opening of a main pipe inside the collection tank.

A continuous freeze dryer having a hopper for supplying product to the inlet of the freeze-drying chamber via a sealed coupling with the inlet. A hopper valve allows the hopper to be sealed and evacuated with a product to be freeze-dried inside. An inlet valve of the freeze-drying chamber and a hopper valve may both be opened to provide a pathway between the hopper and the chamber whilst the hopper and chamber are maintained in an evacuated condition. The hopper may include an internal shell within an external shell with an evacuation port for evacuation a cavity between the shells. A hopper valve allows the supply of product to the freeze dryer via a hopper port. Product may be loaded into a hopper, coupled with the inlet of the freeze-drying chamber, evacuated, a hopper valve opened to supply product to the freeze-drying chamber, and the product conveyed through the freeze-drying chamber.
