This creation relates to a device for producing heat-sealed lactic acid bacteria after fermentation, which includes a tank with a feed inlet, a discharge port, a sampling port and an air supply pipe. A rotating shaft with a stirring blade is located in the tank. And a cold and hot water pipe temperature control system is set on the outer ring of the tank, so that the lactic acid bacteria strains and the culture medium are input into the tank from the feeding port, and the agitation wings and the air supply pipe are continuously aerated and stirred, and the samples are taken from the sampling port. When the bacteria reach the fermentation termination conditions, the tank is heated by using a hot and cold water temperature control system to heat the active lactic acid bacteria in the tank to inactive bacteria, and then exported from the discharge port. Then, the liquid is concentrated and evaporated by the concentration equipment to produce the product. The composite lactic acid bacteria are produced and the biological elements are produced after fermentation for subsequent packaging and sales of the product.本創作係有關一種製作熱封型乳酸菌發酵生產後生元之裝置，其係包含具入料口、出料口、採樣口及空氣供應管之容槽，位於容槽內設有具攪拌翼之轉軸，並於容槽外環設冷熱水管控溫系統，藉此，使乳酸菌菌種及培養基由入料口投入容槽後，藉攪拌翼及空氣供應管持續通氣攪拌，並於由採樣口取樣之菌種達到發酵終止條件時，利用冷熱水管控溫系統加熱容槽，使容槽內活性乳酸菌加熱為非活性菌體，再由出料口導出，接著，經濃縮設備進行液體濃縮蒸發，進而產出複合乳酸菌體及其發酵生產之後生元，以進行產品後續包裝與銷售。
