The present application belongs to the technical field of processing of by-products of brewing, and specifically discloses a method and device for reducing viscosity of distiller's grains based on enzyme treatment, which comprises the following steps: S1, dispersing the distiller's grains of liquor and mixing the auxiliary materials by means of a stirrer; S2, adjusting the pH of the uniformly dispersed and mixed distiller's grains by means of ammonia water, and then adding enzyme hydrolysate, and performing enzymolysis for 24 hours; and S3, further adding decomposition enzyme to perform enzymolysis into sugar. The method and device for reducing viscosity of distiller's grains based on enzyme treatment are used to disperse the distiller's grains and mix the auxiliary materials by means of the inner rotation and outer rotation modes of the stirrer, and to reduce the viscosity of the distiller's grains by means of a two-step enzyme hydrolysis method, so that the viscosity of the distiller's grains is reduced and the saccharification rate of the distiller's grains is improved, thereby laying a foundation for further fermentation of the distiller's grains to produce protein.

The utility model provides a multidirectional adjustable back-of-ear hearing aid fixing mechanism, which relates to the technical field of hearing aids and comprises a hearing aid body, a hanging neck fixedly connected onto the hearing aid body and a clamping structure, the clamping structure comprises a rotating block slidably connected onto the hanging neck, an outer sliding rod is fixedly connected onto the rotating block, and an inner sliding rod is fixedly connected onto the outer sliding rod. A transmission block is fixedly connected to the outer sliding rod, a transmission shaft is connected to the transmission block in a sliding mode, a sliding rod is fixedly connected to the transmission shaft, a sliding frame is fixedly connected to the sliding rod, the sliding frame is connected to the hanging neck in a sliding mode, and a lower sliding frame is fixedly connected to the rotating block. Even if the friction force is reduced due to sweating or grease secretion of the ears of the user, continuous fixing force can still be provided based on mechanical transmission and clamping triggered by pulling of the data line, the reliability and wearing comfort of the fixing mechanism are remarkably improved, and the problem that in the prior art, a fixing mechanism is prone to falling off is effectively solved.

The utility model relates to an assembly type reorganized bamboo frame - shear wall structure belongs to bamboo structure building technical field. The structure includes the frame column of reorganized bamboo, shear wall unit, beam, floor system and foundation. Shear wall unit is formed by the grid -like shear frame of vertical keel and horizontal keel through screw orthogonal connection of staggered arrangement, and the wall panel is fixed in the both sides of framework, frame column and shear wall unit form the stress system of coordination through the rigid connection of bolt, and the anchoring of column foot adopts steel sleeve and opposite -thread bolt and foundation. Horizontal keel staggered arrangement avoids cross section to weaken, and the top keel adopts double -layer structure to enhance the bearing capacity, and the elastic gasket is set up between bottom keel and foundation and buffers earthquake stress. The structure passes through the double defense line design of frame and shear wall, and the interlayer displacement angle is 1 / 53 under 7 degrees rare earthquake through the test verification, and the modular prefabricated component realizes full bolt fast assembly, and the construction efficiency is high, and is applicable to low multilayer low carbon building.
