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 Cordyceps sinensis freeze-drying process comprises the following steps, and the following steps are all operated under purification conditions,

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

[0031] Step 2, the Cordyceps sinensis after the surface is dried is stacked on the pallet in turn, and the stacking thickness of the Cordyceps sinensis on the pallet is 3 layers;

[0032] Step 3: Place the plated Cordyceps sinensis on the double radiant plate in the freeze-drying chamber of the vacuum freeze dryer, bury the temperature probe in the Cordyceps sinensis, close the door of the freeze-drying chamber, and the temperature probe will detect the Cordyceps sinensis during the freeze-drying process. Detect the temperature and transmit the detected temperature signal to the controller of the vacuum freeze dryer;

[0033] Step 4: Start the refrigeration function of the vacuu...

Embodiment 2

[0047] The Cordyceps sinensis freeze-drying process comprises the following steps, and the following steps are all operated under purification conditions,

Embodiment 3

[0065] The Cordyceps sinensis freeze-drying process comprises the following steps, and the following steps are all operated under purification conditions,

[0066] Step 1: Quickly clean the Cordyceps sinensis under the purification condition of a constant temperature of 20°C, and drain the surface water;

[0067] Step 2, the Cordyceps sinensis after the surface is dried is stacked on the pallet in turn, and the stacking thickness of the Cordyceps sinensis on the pallet is 5 layers;

[0068] Step 3: Place the plated Cordyceps sinensis on the double radiant plate in the freeze-drying chamber of the vacuum freeze dryer, bury the temperature probe in the Cordyceps sinensis, close the door of the freeze-drying chamber, and the temperature probe against the Cordyceps sinensis during the freeze-drying process. Detect the temperature and transmit the detected temperature signal to the controller of the vacuum freeze dryer;

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.
