Fuente: WIPO "hemp" The utility model relates to the technical field of separation tanks, in particular to a single-stage extraction separation tank device which comprises a crushing assembly, the crushing assembly comprises a crushing shell, a supporting base, a motor shell, a first servo motor and a connecting pipeline, the crushing shell comprises a feeding port and a flow guide plate, the feeding port is formed in the crushing shell, and the flow guide plate is arranged on the supporting base. And the number of the flow guide plates is two, the two flow guide plates are oppositely installed on the inner surface of the crushing shell, and the stirring assembly is installed on one side of the crushing assembly. Through the design of the crushing assembly, the first servo motor is started, and the two groups of crushing blades are used for crushing hemp raw materials, so that the situation that when cannabinoid is extracted, the hemp raw materials need to be crushed firstly and then moved to a stirrer to be stirred, the working procedure is complex, and the working efficiency is low is avoided.
