Problems solved by technology

Fresh products have complete nutrients and are easy to absorb by the human body. However, fresh products have high requirements on storage temperature, humidity and storage environment, and their freshness and preservation are subject to many restrictions. The branches and tendrils are shaped into maple buckets while being heated. The dried dendrobium dendrobium prepared by this baking method is inconvenient to eat. Timely heating causes partial destruction of active substances, reduces the content of active ingredients such as polysaccharides, and affects their medicinal value.
How to keep the nutritional components and active substances of Dendrobium dendrobium to the greatest extent, and make the finished product of Dendrobium dendrobium long-term preservation and convenient to eat is the common expectation of people, but there is no report on related technologies so far

Embodiment 1

[0025] 1. Materials: Select the fresh branches of Dendrobium dendrobium at the best harvest time (attached figure 1 ), washed with tap water, and removed the leaf sheaths.

[0026] 2. Cut into sections: Rinse the fresh branches of Dendrobium dendrobium with deionized water for a second time, drain, then cut into 5.0-10mm long sections, and put them on a plate for later use.

[0027] 3. Pre-cooling: Set the pre-cooling temperature of the ultra-low temperature refrigerator to -80oC, put the Dendrobium dendrobium segment into the pre-cooling, and the time is 5 hours until it is completely frozen.

[0028] 4. Vacuum freeze-drying: first open the cold trap to pre-cool for 40 minutes, and when the temperature of the cold trap drops to -62oC, place the frozen Dendrobium dendrobium segment above the cold trap cavity and seal it with a cover to carry out vacuum freeze-drying. The temperature of the cold trap is kept at Between -62.5oC~-66.6oC, the vacuum degree drops to 5.0Pa in 25 m...

Embodiment 2

[0032]1. Material collection: Select the fresh branches of Dendrobium dendrobium at the best harvest time, wash them with tap water, and remove the leaf sheaths.

[0033] 2. Cut into sections: Rinse the fresh branches of Dendrobium dendrobium with deionized water for a second time, drain, then cut into 5.0-10mm long sections, and put them on a plate for later use.

[0034] 3. Pre-cooling: Set the pre-cooling temperature of the ultra-low temperature refrigerator to -80oC, put the Dendrobium dendrobium segment into the pre-cooling, and the time is 6 hours until it is completely frozen.

[0035] 4. Vacuum freeze-drying: first open the cold trap to pre-cool for 60 minutes, and when the temperature of the cold trap drops to -64oC, place the frozen Dendrobium dendrobium segment above the cold trap cavity and seal it with a cover to carry out vacuum freeze-drying, and the temperature of the cold trap is kept at Between -64oC~-68oC, the vacuum degree drops to 7.0Pa in 20 minutes, then...

Abstract

The invention provides a method for processing fresh dendrobium devonianum stem powder. The method comprises the following steps: washing and peeling fresh dendrobium devonianum stems, cutting into sections, precooling, freeze-drying, crushing with liquid nitrogen, and drying at low temperature to prepare light yellow green dendrobium devonianum powder, wherein the fresh dendrobium devonianum stems are precooled by adopting a cryogenically quick-freeze method after being cut into sections to freeze the fresh dendrobium devonianum stems; the frozen dendrobium devonianum sections are put into a cold trap for vacuum freeze-drying and are ground into powder by virtue of a liquid nitrogen grinding machine, are dried in a thermostat at low temperature of 60-80 DEG C for 1-3 hours; and the dried powder is sealed and packaged.

Description

technical field [0001] The invention relates to a processing method of a dendrobium dendrobium product, in particular to a processing method of a dendrobium dendrobium fresh branch powder. technical background [0002] Dendrobium dendrobii Dendrobium devonianum Paxt., also known as Dendrobium dendrobii, is a plant of the genus Dendrobium in the family Orchidaceae. Stem drooping, slightly fleshy, thin cylindrical, 50-70 (-100) cm long, 3-5 mm thick, unbranched, with many nodes, internodes 2.5-4 cm long, often pale brown with stained black after drying . Leaves papery, two rows alternate on the whole stem, narrowly ovate-lanceolate, 8-13 cm long, 1.2-2.5 cm wide, apex long acuminate, base with clasping sheaths; leaf sheaths often have purplish red spots, Papery when dry. Dendrobium has a long history of medicinal use. It is a traditional precious Chinese medicine in my country. It has medicinal and health effects. Dendrobium stems contain a variety of alkaloids, polysaccha...
