PZ-TQ-1 microwave extractor

Product name: microwave extractor

Specification and model: PZ-TQ-1

Microwave extraction technology has been applied to spices, condiments, natural pigments, Chinese herbal medicine, cosmetics, soil analysis and other fields.

1. Microwave extraction mechanism

Microwave extraction is that high-frequency electromagnetic wave penetrates the extraction medium and reaches the inside of the extracted material. Microwave energy can be rapidly converted into heat energy to make the internal temperature of the cell rise rapidly. When the internal pressure of the cell exceeds the bearing capacity of the cell wall, the cell breaks, and the effective components in the cell flow out freely. The extracted material is obtained by dissolving in the extraction medium at a lower temperature and further filtering and separation. Under the action of microwave radiation, the components of the extracted material accelerate the diffusion to the interface of the extraction solvent, thus increasing the extraction rate several times, and also reducing the extraction temperature and the extraction quality.
2. Advantages of microwave extraction
Traditional thermal extraction is carried out from the outside to the inside by means of heat conduction and thermal radiation, while microwave extraction is carried out by heating the material inside and outside at the same time. Compared with traditional thermal extraction, the main advantages of microwave extraction are:
A. High quality, which can effectively protect the functional components in food, medicine and other chemical materials;
B. High extraction rate;
C. High selectivity for extracts;
D. Fast and time-saving, which can save more than 50% - 90% of the time;
E. Less solvent consumption (more than 50% - 90% less than conventional methods);
F. Safe, energy-saving, pollution-free, simple production equipment and investment saving.

Overview of microwave extraction equipment
The equipment used for microwave extraction is roughly divided into two categories: one is microwave extraction tank, and the other is continuous microwave extraction line. One of the main differences between the two is that the materials are processed in batches, similar to the multi-function extraction tank; The other is the extraction equipment that works in a continuous manner. Specific parameters are generally designed by the manufacturer according to user requirements.
