Problems solved by technology

[0002] In the prior art, Cordyceps sinensis is mostly processed by drying, but by drying, the nutrients in Cordyceps sinensis will be lost more, and the nutritional value of Cordyceps sinensis cannot be guaranteed. In order to fully retain the nutritional value of Cordyceps sinensis, there have also appeared Freeze-drying technology is adopted, but the existing freeze-drying technology can only adopt a single-layer tiling process, and the drying process does not achieve gradient and precise control of heating temperature, resulting in low yield and high shriveled rate of finished products (≥8%) ), high energy consumption during production

Embodiment 1

[0029] The freeze-drying process of Cordyceps sinensis includes the following steps: the following steps are all operated under purification conditions,

[0030] Step 1: Quickly clean the Cordyceps sinensis at a constant temperature of 15°C under purification conditions, and drain the surface water;

[0031] Step 2: After the surface is dried, the cordyceps are sequentially stacked on the tray, and the stacking thickness of the cordyceps on the tray is 3 layers;

[0032] Step 3: Place the plated Cordyceps on the dual radiation plate in the freeze-drying chamber of the vacuum freeze dryer, and bury the temperature probe in the cordyceps, close the door of the freeze-drying chamber, and the temperature probe will affect the temperature of the cordyceps during the freeze-drying process. The temperature is detected and the detected temperature signal is transmitted to the controller of the vacuum freeze dryer;

[0033] Step 4: Start the refrigeration function of the vacuum freeze dryer un...

Abstract

The invention relates to the technical field of freeze drying, in particular to a freeze drying process of cordyceps sinensis. The freeze drying process comprises the following steps: the cordyceps sinensis is cleaned, and water on the surface is dried; the cordyceps sinensis is stacked on a tray in sequence; the dished cordyceps sinensis is put on a dual radiation plate in a freeze drying bin of a vacuum freeze drying machine, and a door of the freeze drying bin is closed; in a normal pressure state, a refrigerating function of the vacuum freeze drying machine is started to refrigerate the dual radiation plate; a cold trap refrigerating mode is opened, and a vacuum pump is opened to vacuumize the freeze drying bin; a heating circulating pump is opened, and the temperature of the dual radiation plate is controlled to gradually increase the material temperature; the operation of equipment is stopped, and the door of the bin is opened to take out the cordyceps sinensis for warehousing. The freeze drying process can keep the appearance of the cordyceps sinensis consistent with that of fresh cordyceps sinensis to improve the product quality, guarantees no loss of nutritive value and medical value of the cordyceps sinensis, can guarantee consistency of the water content of the cordyceps sinensis after freeze drying, and prolongs the shelf life of products.

Description

Technical field [0001] The invention relates to the technical field of freeze-drying, in particular to a freeze-drying process of Cordyceps sinensis. Background technique [0002] In the prior art, most of the Cordyceps sinensis is treated by sun-drying. However, the nutrient content in the Cordyceps will be lost more by the sun-drying method, and the nutritional value of the Cordyceps cannot be guaranteed. In order to fully retain the nutritional value of the Cordyceps, it has also appeared The freeze-drying technology is adopted, but the existing freeze-drying technology can only adopt a single-layer flat processing technology. The drying process does not achieve a gradient to accurately control the heating temperature, which leads to low yield and high drying rate of finished products (≥8%) ), high energy consumption in the production process. Summary of the invention [0003] In view of the above technical problems, the present invention provides a process for freeze-drying C...
