Microwave extraction production line
Under the existing equipment and the tea extract ammonia base , Tan and other production experience , microwave extraction equipment production line mainly includes four aspects : pretreatment, microwave extraction, separation and concentration system liquid material . The following section briefly describes the corresponding process is divided into four treatment .
1 smash , feeding
Like the traditional extraction , crushing herbs properly , can increase the contact area is conducive for extraction , microwave extraction of the characteristics usually required to be based on crushed herbs of 2 - 10mm particles to facilitate feeding and inhibition during feeding dust flying , special features in the workshop to the feed room , the crushed herbs put in the addition vessel , transported by pipeline to the extraction tank , the vacuum conveyor generally more appropriate manner .
    2 Preheat solvent
Microwave extraction at different temperatures results vary greatly, the microwave power , solvent , medium , extraction amount is exactly the same circumstances , the hot extraction is better than the cold state , which is not obvious from the small extraction experiment , but in the large production is especially important .
Consider the design of the solvent using a plate heat exchanger is heated to a suitable temperature .
    How much water content is directly related to the operating time , but also directly affect the extraction yield of the low water content of the herbs are mainly seeds humidifier measures should be taken in order to effectively absorb microwave energy in the microwave before extraction
Soaked in solvent can be added , this operation can be carried out in the microwave extraction tank .
