Embodiment Construction

[0020] A gaseous carbon dioxide dehydration process for fruit and vegetable foods and leaf-shaped plants, the process flow is:

[0021] Step 1: Preparation Process

[0022] Put the washed and sliced ​​vegetable food or leafy plant, or the semi-finished product of fruit and vegetable food or leafy plant that has been dehydrated in advance into the dehydration tank → close the door of the dehydration tank and seal it → open the dehydration tank exhaust valve Vacuum the inside of the dehydration tank. The dehydration tank can be vertical or horizontal; a production line can be installed with one dehydration tank, or multiple dehydration tanks can be installed in parallel.

[0023] The second step: dehydration process

[0024] Open the release valve of the gaseous carbon dioxide tank and the intake valve of the dehydration tank → the carbon dioxide gas enters the dehydration tank, and when the pressure in the dehydration tank reaches a certain pressure value, close the release v...

Abstract

The invention discloses a process for dehydrating fruits and vegetables and foliated plants with gaseous carbon dioxide and relates to the 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) ensuring the carbon dioxide to enter into the dehydration tank and maintaining the pressure for a period of time, releasing the carbon dioxide and removing the moisture of the materials in the dehydration tank along with release of the carbon dioxide, ensuring the carbon dioxide to enter into a recovery tank, closing the intake valve of the recovery tank after the pressure in the dehydration tank and the pressure in the recovery tank are balanced, and opening the blowoff valve of the dehydration tank to discharge the residual carbon dioxide in the dehydration tank to the atmosphere; (3) opening the bin gate of the dehydration tank and taking out the materials in the tank; (4) signing and issuing the certificates of approval and dates of manufacture after passing the inspection; and (5) packaging and warehousing.

Description

[0001] The invention relates to a process for dehydrating fruit and vegetable foods and leaf-shaped plants, in particular to a process for dehydrating leaf-shaped fruits and vegetables and Chinese medicinal materials with gaseous carbon dioxide. 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-temperature...
