Example Embodiment

[0021] Example one:

[0022] Fresh Dendrobium nobile has leaves, washed with tap water, drained naturally, and cut into 2cm pieces. Spread a layer in a small microwave oven to ensure that it is evenly heated in the microwave. Then microwave drying is carried out. The first stage microwave power is 1100w, the drying time is 15min, the second stage microwave power is set to 600w, the drying time is 30min, and the dried product of Dendrobium nobile (moisture content is 10.9%) is obtained. The dried product is crushed to 15-30 meshes (mesh) by a stainless steel Chinese medicine crusher, and is packaged with a tea bag packaging machine to obtain powdered Dendrobium tea.

Example Embodiment

[0023] Embodiment two:

[0024] Fresh Dendrobium nobile is removed from the leaves, washed, and dried by a spin dryer, then cut into 20 cm pieces. Spread one layer into a tunnel microwave dryer for the first stage of microwave drying. The microwave power is 1500w and the drying time is 10min. Take it out and cool to below 40℃. Use a stainless steel Chinese medicine microtome to slice. It can be an oblique slice. Or round slices; place another layer in a tunnel-type (vacuum) microwave dryer for the second stage of microwave drying, the microwave power is set to 900w, the drying time is 15min, and the dried Dendrobium nobile slices are obtained (the moisture content is 11.3% ). The slices are packed in bags of Dendrobium sliced ​​tea with aluminum-plastic conforming bags that meet the requirements of food packaging materials.

Example Embodiment

[0025] Example three:

[0026] Fresh Dendrobium nobile is removed from leaves, washed, drained naturally, and cut into 10cm pieces. Spread one layer into the tunnel microwave dryer for the first stage of microwave drying, the microwave power is 2000w, the drying time is 8min, take it out and cool to below 40℃, slice it with a stainless steel Chinese medicine slicer, which can be an oblique slice Or round slices; place another layer in a tunnel-type (vacuum) microwave dryer for the second stage of microwave drying, the microwave power is set to 1100w, the drying time is 10min, and the dried Dendrobium nobile slices are obtained (the moisture content is 11.5%) ). The slices are packed with aluminum-plastic conformal bags that meet the requirements of food packaging materials to obtain Dendrobium sliced ​​tea in bags. The dried product slices are pulverized by a stainless steel Chinese medicine pulverizer to a particle size of 15-30 mesh (mesh), and are packaged with a tea bag...

Abstract

A method for preparing powder tea by adopting microwave drying of dendrobium nobile lindl comprises the following steps: leaves of fresh dendrobium nobile lindl are removed, the fresh dendrobium nobile lindl is washed, drained and placed in a 500-3,000 w microwave field to dry for 5-60 min until the water content is 50%; then the dendrobium nobile lindl is cut into slices by a traditional Chinese medicine slicer, the dendrobium nobile lindl slices are placed in 500-1,500 w microwave to dry for 5-30 min, and a dry dendrobium nobile lindl product with the water content lower than 12% is obtained; and the dry dendrobium nobile lindl product is pulverized by a pulverizer and bagged. The method has the advantages of high heating speed, uniform inner and outer heating, sterilization, non-pollution, low carbon, energy saving, low production cost and high drying efficiency, and can further improve the heating quality greatly, maintain nutritional components of the raw material and prevent damage and loss of active ingredients in the material.

Description

Technical field [0001] The invention relates to a method for preparing powdered tea using microwave drying of Dendrobium nobile, and belongs to the technical field of drying and processing methods of Chinese medicinal materials. Background technique [0002] Dendrobium nobile ( Dendrobium nobile Lindl ) Is Orchid ( Orchidaceae ) Dendrobium ( Dendrobium Sw.) Perennial epiphytic herb, also known as flat golden hairpin, flat yellow grass, and yellow grass, is a traditional Chinese medicine of my country. It is used as medicine with fresh or dried stems.
