Embodiment 1

[0028] (1) Wash Morinda officinalis with clean water and cut into 7mm slices with a slicer;

[0029] (2) The cleaned Morinda officinalis is blanched and sterilized with high-humidity superheated steam: the blanching temperature of the superheated steam is 120℃, the relative humidity is 30%, the gas flow rate is 12m / s, and the blanching time is 60s;

[0030] (3) Carry out the vacuum pulsation drying of Morinda officinalis after the blanching and enzyme sterilization treatment: the drying temperature in the drying chamber is 50℃, the vacuum degree is between 0MPa and 0.05~0.095MPa, and the pulse ratio is 10min:2min. Stop drying when the moisture content of Morinda officinalis drops to 15%;

[0031] (4) Carry out vacuum microwave drying of Morinda officinalis after vacuum pulse drying: microwave power density is 0.6W / g, relative pressure is 0Mpa, microwave action time is 20 minutes, when Morinda officinalis moisture content is 10%, stop drying .

Embodiment 2

[0033] (1) Wash Morinda officinalis with clean water and cut into 8mm slices with a slicer;

[0034] (2) The cleaned Morinda officinalis is blanched and sterilized with high-humidity superheated steam: the blanching temperature of the superheated steam is 100℃, the relative humidity is 40%, the gas flow rate is 20m / s, and the blanching time is 80s;

[0035] (3) The Morinda officinalis after the blanching and enzyme sterilization treatment is subjected to vacuum pulsation drying: the drying temperature in the drying chamber is 60 ℃, the vacuum degree is between 0 MPa and 0.05 to 0.095 MPa, and the pulse ratio is 12 min: 4 min. Stop drying when the moisture content of Morinda officinalis drops to 20%;

[0036] (4) Carry out vacuum microwave drying of Morinda officinalis after vacuum pulse drying: microwave power density is: 2W / g, relative pressure is 0.08Mpa, microwave action time is 30 minutes, when Morinda officinalis moisture content is 10%, stop drying .

Embodiment 3

[0038] (1) Wash Morinda officinalis with clean water and cut into 9mm slices with a slicer;

[0039] (2) The cleaned Morinda officinalis is blanched and sterilized with high-humidity superheated steam: the blanching temperature of the superheated steam is 110℃, the relative humidity is 30%, the gas flow rate is 40m / s, and the blanching time is 90s;

[0040] (3) Carry out the vacuum pulsation drying of Morinda officinalis after the blanching and enzyme sterilization treatment: the drying temperature in the drying chamber is 65°C, the vacuum degree is between 0MPa and 0.05~0.095MPa, and the pulse ratio is 12min:6min. Stop drying when the moisture content of Morinda officinalis drops to 25%;

[0041] (4) Carry out vacuum microwave drying of Morinda officinalis after vacuum pulse drying: microwave power density is: 3W / g, relative pressure is 0.08Mpa, microwave action time is 40 minutes, when the moisture content of Morinda officinalis is 8%, stop drying .

Abstract

The invention relates to a method for drying morinda officinalis through combining vacuum pulsation and microwaves, and belongs to the technical field of traditional Chinese medicinal material processing. The processing method comprises the following operation steps: cleaning, slicing, carrying out enzyme deactivation and sterilization treatment, carrying out vacuum pulse drying and carrying out microwave drying. The method has the advantages of high effective component retention rate, short drying time, good quality, cleanness, sanitation and the like.

Description

Technical field [0001] The invention relates to a method for drying Morinda officinalis in combination with vacuum pulsation and microwave, and belongs to the technical field of Chinese herbal medicine processing. Background technique [0002] Drying of Chinese medicinal materials can not only extend the shelf life of Chinese medicinal materials, improve product quality, but also help maintain the effective ingredients of medicines to the greatest extent. Traditional drying methods are greatly affected by region, climate, and weather. Drying conditions are difficult to control, time-consuming, and product quality is not uniform. Therefore, the initial processing and drying of Chinese medicinal materials should be combined with the characteristics of medicinal plants, and modern drying technology should be used to carry out high-quality and efficient drying on the basis of retaining the effective medicinal ingredients to the greatest extent. [0003] Modern drying technology mainly...
