摘要:
A method of defrosting frozen products of the present invention is the method of carrying out microwave heating while reducing the pressure, terminating microwave heating upon detection of a microwave-induced electrical discharge during the microwave heating step, reducing the pressure while microwave heating is in a terminated state to a pressure level at or below a sublimation pressure level to generate sublimation on the frozen products, returning the pressure to a prescribed pressure level to enable microwave heating to be restarted, and repeating the steps from the microwave heating step through the pressure returning step a prescribed number of times.

In the conventional technology, macromolecular polysaccharides, which the aloe vera gel inherently has, are broken down into small molecules for the following reasons: First, cellulose is broken down by the enzyme such as cellulose; Second, agitation in the cellulose breakdown process by the enzyme of cellulase and the like is performed in a heated state for an extended period of time; Third, nearly the same technique is employed also in the aloin absorption process by the activated charcoal; Fourth, a plurality of times of filtering causes intense oxidation to the gel juice. For the reasons described above, the molecular weight of macromolecular polysaccharides, which the aloe vera gel inherently has, is reduced to 80,000 dalton or less. Therefore, by use of the conventional technology, it is impossible to provide macromolecular polysaccharides that the aloe vera gel has in a state where aloin is removed. To solve the above-mentioned problem, we provide aloe powder which is made from aloe vera gel, characterized by that a molecular weight of polysaccharides contained in the powder is not less than 400,000 dalton and an aloin content ratio of the powder is not more than 50 ppm.

A method of drying objects includes the steps of placing the objects into a pressure reduction tank, placing a metallic element having a single or plural number of sharp edge into the pressure reduction tank, subjecting the objects to controlled microwave heating and controlled far infrared heating either separately or simultaneously, detecting an electrical discharge at the sharp edge of the metallic element due to microwave energy, stopping or pausing the microwave heating when an electrical discharge is detected at the single or plural number of sharp edge of the metallic element, continuously measuring the change in reduced pressure at prescribed time intervals after the microwave heating has been stopped or paused upon detecting an electrical discharge due to microwave energy, and terminating the drying process when the measured change in reduced pressure reaches a predetermined target reduced pressure change value determined in accordance with the level of dryness selected and the type of the objects being dried.

A freeze-drying method by a far infrared heater including the steps of: mounting the frozen objects to be dried prior to heating in the containers in which an absorption power of the radiant heat from the far infrared heater and a thermal conductivity are high, respectively; mounting the said objects which are contained in the containers into the reduced pressure tank under an atmospheric pressure; heating the containers by the radiant heat from the far infrared heater disposed in the reduced pressure tank; and sublimating the frozen water contents of the objects in a reduced pressure state where sublimation of the objects occurs in the reduced pressure tank.

A method of drying objects includes the steps of placing the object into a pressure reduction tank, placing a metallic element having an acute-angled portion into the pressure reduction tank, reducing to the pressure toward a predetermined single reduced pressure value or plurality of reduced pressure values, subjecting the object to controlled microwave heating and controlled far infrared heating either separately or simultaneously, continuously heating the body of the pressure reduction tank to vaporize any water that comes into contact with the inside wall surfaces of the pressure reduction tank, detecting an electrical discharge at the acute-angled portion of the metallic element due to microwave energy, stopping or pausing the microwave heating when an electrical discharge is detected at the acute-angled portion of the metallic element, continuously measuring the change in reduced pressure at prescribed time intervals after the microwave heating has been stopped or paused upon detecting an electrical discharge due to microwave energy, and terminating the drying process when the measured change in reduced pressure reaches a predetermined target reduced pressure change value determined in accordance with the level of dryness selected and the type of object being dried.
摘要:
The present invention aims to freeze and store organs or tissues taken from human bodies or animals and after thawing, use the resulting organs or tissues, or cells taken and extracted therefrom for medical treatment. The present invention is characterized in that the organs or tissues taken from human bodies or animals are regenerated through the steps of freezing, storing and thawing; the cells taken from the organs or tissues undergo cell division and colonization.
摘要:
Microwave and far infrared heating under reduced pressure is carried out on objects to be dried, concentrated, defrosted, roasted or sterilized by placing the objects in plate-shaped or tray-shaped object-holding jigs arranged on a shelf-type jig which is held motionless in a pressure reducing chamber during heating, wherein the provision of reflector plates, reflective frames, specific object-holding jigs and cutting methods are employed to achieve uniform heating.
