Example Embodiment

[0021] A liquid carbon dioxide dehydration process for fruit and vegetable foods and Chinese herbal medicine plants is characterized in that the process flow is:

[0022] The first step: preparation process

[0023] Put the washed and sliced ​​fruits and vegetables or Chinese herbal plants, or semi-finished products from which free water has been removed in advance, into the dehydration tank → close the dehydration tank door and seal → open the dehydration tank exhaust valve to vacuum the dehydration tank. The dehydration tank can be vertical or horizontal; one production line can be installed with one dehydration tank, or multiple dehydration tanks can be installed in parallel.

[0024] Step 2: Dewatering process

[0025] Open the liquid carbon dioxide tank discharge valve and the gasifier inlet valve → liquid carbon dioxide is converted into gaseous carbon dioxide by the gasifier → gas compressor pressurizes the gaseous carbon dioxide → gas separator → open the gas separator gas rel...

Abstract

The invention discloses a process for dehydrating fruits and vegetables and Chinese herbal medicine plants with liquid carbon dioxide and relates to a fruit and vegetable and Chinese herbal medicine processing process. The process comprises the following flows: (1) putting the sliced fruits and vegetables, Chinese herbal medicines or semifinished products from which the free water is removed in advanced into a dehydration tank, closing the bin gate of the dehydration tank and sealing and vacuumizing the dehydration tank; (2) opening a liquid carbon dioxide tank bleeder valve, gasifying the liquid carbon dioxide, then pressurizing the gaseous carbon dioxide by virtue of a compressor, entering into a gas-distributing tank, entering into the dehydration tank, maintaining the pressure for a period of time after the pressure in the dehydration tank reaches a certain pressure value, entering into a high-pressure recovery tank, entering into a low-pressure recovery tank, pumping and pressurizing the gases in the dehydration tank and the recovery tanks by virtue of a gas recovery compressor, flowing back to the gas-distributing tank, ensuring the recovery compressor to stop working when the pressure in the dehydration tank is approximate to the atmospheric pressure and closing the intake valve of the high-pressure recovery tank and opening the blowoff valve of the dehydration tank to discharge the residual carbon dioxide in the dehydration tank to the atmosphere; (3) taking out the materials in the tank; (4) carrying out inspection; and (5) packaging and warehousing.

Description

technical field [0001] The invention relates to a dehydration process for fruit and vegetable foods and Chinese herbal medicine plants. Not only suitable for leaf-like plants, but also suitable for dehydration of blocky, rod-like and root-like plants. Background technique [0002] The world's food industry is developing towards natural, health-care and convenient trends. Dehydrated fruits and vegetables are becoming more and more popular because they are natural, green, nutritious, easy to carry, and have a long shelf life; Finally, the packaging is convenient for transportation and can be stored for a long time. At present, plant dehydration generally adopts the dehydration process of oven high-temperature drying and vacuum low-temperature freeze-drying process. Oven high-temperature drying and dehydration process has the characteristics of small equipment investment, simple process, and easy operation. Low efficiency, poor sanitation and other defects. The vacuum low-t...
