Corn stalk grass powder processing technology

Corn stalk grass powder processing technology

The corn stalks are crushed into grass powder, fed to cattle and sheep after fermentation, used as feed instead of hay, and seasons are more likely to be consumed during the busy season, and the feeding effect is better. Any non-mildew, corn stalk with moisture content of not more than 15% can be crushed raw materials, when the production of hammer crusher to smash the straw, grass powder should not be too fine, generally 10 to 20mm long, 1-3mm wide, too thin is not easy to ruminant. The comminuted corn straw grass powder and leguminous grass powder are mixed in a ratio of 3:1. The whole fermentation time is 1 to 1.5 days. The fermented grass powder is added 0.5 to 1 kg of bone meal per 100 kg, and is assigned to 25 people. - 30kg of cornmeal, wheat bran, etc., fully mixed, it will be made of grass powder fermentation mixed feed.

The chair side CAD / CAM repair system has obvious advantages in aesthetic effect, operation time, patient participation and operation convenience. Discussion: traditional repair method: after the model is transferred, it will be sent to the technician's room for processing and making the final prosthesis. About one week, the final prosthesis will be tried on, grinded and bonded. The prosthesis was made in the technician's room. The patients need to accept the aesthetic effect of the prosthesis passively without any sense of participation. The implant repair method of chair side CAD / CAM system: obtain computer three-dimensional model by blue light scanning method, design and make personalized abutment and all ceramic restoration on computer, dye, glaze and bond after trial wearing, the whole restoration is made by chair side, patients can directly participate in the restoration design, and feel more involved. Conclusion: in the implant area of the anterior teeth, compared with the traditional implant repair method, the chair side repair system can get more satisfactory results, which is worthy of clinical application and promotion.
