The utility model discloses a drying device for lepidolite beneficiation, and relates to the technical field of lepidolite, the drying device comprises a transmission mechanism, a drying device body and a placement flat plate, one side of the placement flat plate is fixedly connected with a position control shell, the inner wall of the position control shell is slidably connected with a position control sliding block, and a position control cam is slidably connected in a guide groove formed in the position control sliding block; the position control cam is rotationally connected to one side of a transition insertion plate, one end of the transition insertion plate is fixedly connected with a first grid baffle, and the transition insertion plate is slidably connected to the inner wall of the position control shell. Through the arrangement of the placement flat plate, the position control shell, the position control sliding block, the position control cam, a transition inserting plate, a first grid baffle, a power single rod, a first translation sliding block, a guide single rod, a guide single rod, a position control sliding way, a second translation sliding block, an L-shaped auxiliary plate, a second grid baffle, an electric push rod and a linkage supporting plate, the conveying form of mineral raw materials can be effectively changed; and free switching between a single track and double tracks can be realized, so that the practical effect can be effectively enhanced.

The utility model relates to the technical field of drying equipment, and particularly discloses a drying device for tremella sporocarp polysaccharide production, which comprises a preheating drying chamber, a heating drying chamber and a constant-temperature drying chamber, the preheating drying chamber comprises a preheating cavity which is upwards inclined, a rotatable preheating conveying belt which is arranged in the preheating cavity, a first preheating air distribution plate which is arranged above the preheating conveying belt and is parallel to the preheating conveying belt, and a second preheating air distribution plate which is arranged in the preheating conveying belt and is parallel to the preheating conveying belt; the heating drying chamber comprises a heating cavity, and an upper heating conveyor belt and a lower heating conveyor belt which are horizontally distributed in the heating cavity from top to bottom in sequence in a staggered manner; the preheating cavity, the heating cavity and the constant-temperature cavity are respectively provided with a heat pump dryer for providing hot air; meanwhile, a sectional drying mode is adopted, preheating drying is conducted firstly, then heating drying is conducted, and finally constant-temperature drying is conducted, so that the drying effect of the tremella sporocarp can be optimized, active ingredients in the tremella sporocarp can be reserved, and the quality of tremella sporocarp extraction in the later period can be improved.

The utility model discloses energy-saving vacuum freeze drying equipment which comprises a drying bin, door opening and closing devices symmetrically and fixedly connected to the outer wall of the top of the drying bin, opening and closing doors rotationally connected to the outer walls of the bottoms of the door opening and closing devices, and trapping devices symmetrically and fixedly connected to the inner wall of the drying bin. The utility model relates to the technical field of vacuum freeze drying, in particular to an ice melting device, which is characterized in that an upper door plate and a lower door plate of the ice melting device are connected in a sliding manner through a sliding rail on the outer wall, so that each ice melting device can be independently switched between an open state and a closed state, ice melting operation is carried out on only one fourth of the whole ice melting device each time, and water vapor is continuously collected by the rest three fourths of the ice melting device. According to the ice melting device, part of the trapping devices are always kept in a water vapor trapping state, the situation that the ice melting time and frequency are increased due to the fact that traditional equipment cannot conduct drying operation during ice melting or too many trapping devices conduct ice melting is avoided, and energy loss and time cost in the ice melting process are reduced.
