Spraying type concentrating pan

Abstract

The utility model relates to the technical field of plant extraction and concentration, in particular to a spraying type concentration pot which comprises a pot body, a pot cover and a liquid outlet arranged at the bottom of the pot body, and further comprises a plurality of spray heads arranged on the pot cover and positioned at the top of a cavity of the concentration pot, the feed liquid pipe is arranged on the outer side of the concentrating pan, one end of the feed liquid pipe is connected with a liquid outlet in the bottom of the pan body, the other end of the feed liquid pipe is connected with a plurality of spray heads, and a feed valve is arranged at the top of the feed liquid pipe; the transverse baffle frame is arranged in the cavity of the concentrating pan, the bent silk screen group is mounted on the transverse baffle frame, and feed liquid sprayed by the spray head flows downwards along the bent silk screen group, drops to the lower part of the concentrating pan through the bent silk screen group and then circulates to the spray head through a feed liquid pipe. The negative pressure concentration device has the advantages that the evaporation area of concentrated liquid is enlarged, and the evaporation area is further enlarged to achieve the purpose of rapid concentration under the negative pressure condition by combining a liquid heating method and a negative pressure water vapor extraction method through the bent and wave-shaped silk screen group arranged on the crosspiece frame in the concentration pot.
