The extraction device is an extraction device for extracting the content of a container with high pressure rapid heating water to obtain the corresponding juice, suitable for treating the container (capsule) packed with ingredients capable of producing beverages or edible juices upon interaction with a liquid, such as hot pressurized water, introduced into the capsule. The extraction equipment comprises a water pump, a heating boiler and an extraction assembly, wherein the extraction assembly comprises a first machine part and a second machine part which can move relatively, the second machine part slides to be in contact with the first machine part, and then the second machine part is sealed and closed to form a sealed extraction cavity for accommodating capsules, a liquid outlet channel is arranged in the first machine part, a back pressure valve is arranged at the liquid outlet channel for ensuring certain extraction pressure, and the liquid outlet channel is connected to a liquid outlet nozzle of the extraction equipment through a liquid outlet pipe.
The existing extraction equipment is only suitable for extracting one substance, for example, a coffee machine can only extract coffee, and if the coffee machine is used for extracting tea leaves or traditional Chinese medicinal materials, the residual materials in a liquid outlet channel and a liquid outlet pipe can affect other beverages. Especially, in the decocting machine, the mutual influence of the liquid medicine extracted by two different extraction substances is avoided, when the traditional decocting machine is used for decocting the next pair of Chinese herbal medicine, the liquid medicine of the previous pair of Chinese herbal medicine still has certain residue, the adverse influence on the decoction of the next pair of Chinese herbal medicine is avoided, and even the risk of mutual restriction of the two pairs of Chinese herbal medicine can occur.
The reason is that the extraction device needs to be additionally provided with a liquid outlet channel with back pressure, and if the extraction container which can directly fill the extracted juice with the extraction substances through one time can be designed, the cross contamination generated when the extraction device extracts different extraction substances can be avoided.
In the longitudinal view of the existing various beverage capsule structures, only one containing cavity for containing quantitative extracts (such as coffee powder) is provided, namely, the existing capsules can only perform primary extraction and cannot realize graded extraction, so that extraction materials with higher extraction requirements (high-temperature pressure extraction is required and extraction channels are longer) are extracted, medicinal materials are extracted for example, the medicinal materials cannot be mixed, medicinal materials are extracted for the medicine, and the common capsules are unsuitable.
