This invention relates to the field of beer production technology and discloses a mixing device and process for beer production. The device includes a tank with an upper water pipe and a lower liquid pipe at its upper and lower ends, respectively. The side wall of the tank has inlet and outlet ports. An internal filter screen is installed inside the tank. The tank also contains a stirring shaft, a rotating ring, a vertical rod, an anchor-shaped paddle, and a tillering paddle. The stirring shaft is rotatably mounted inside the tank. This mixing device, through the arrangement of the stirring shaft, rotating ring, vertical rod, anchor-shaped paddle, and tillering paddle, and in conjunction with a lifting control mechanism, achieves synchronous reverse lifting and lowering movements of the anchor-shaped paddle and the tillering paddle. This eliminates the need to transfer the mash and malt between the mashing tank and the filter tank, thus completing the integrated mashing and malt washing process. This effectively shortens the production process, reduces equipment footprint, avoids heat loss and material residue during wort transfer, improves raw material utilization and production efficiency, reduces the risk of microbial contamination, and ultimately ensures the quality of the produced beer.

This invention discloses a deep defluorination device and its defluorination process for wastewater, relating to the field of defluorination equipment. It includes a resin column with an inner temperature-regulating column coaxially arranged inside and an outer temperature-regulating column coaxially arranged on its outer wall. The inlet of the outer temperature-regulating column is located at its top, and its outlet is located at its bottom. The inlet and outlet of the inner temperature-regulating column are opposite to those of the outer temperature-regulating column. A spiral tube is located inside the outer temperature-regulating column, with its top end connected to both an air inlet pipe and a regeneration liquid inlet pipe located outside the resin column.
