Discussion about the key procedure to increase the yield of sufu pehtze;

The experiment of improving yield of the sun vinegar under the economical scale;

Improve the production rate of making solid vinegar;

It was helpful to increase the degrading of starch and protein,thus enhancing the flavors of soy sauce and improving production rate.

5%)lead to different effect:production rate was improved to 2.

Effect of different extraction process on product rate of chicken ossein protein from chicken bone slag;

In order to increase the salted effect and the product rate of the syrup chicken-wing,The modern tumbling technology and the orthogonal experiment were used to carry out the optimized design in this experiment.

The aim of this research is to seek the best formula of rolling the chicken wing and the best craft condition,to analyze through the experiment to the product rate,looked how condition suits the industrial production and combines the appraisal table to look how flavor suits populace\'s taste.

The concepts of raw material utilization ratio,product yield ratio,product qualification ratio as well as the importance for the enterprise are discussed.

By properly determining the dimensions of the feeder and its neck according to the principle of pressure-controllable feeder to control the inner pressure of casting,the shrinkageless casting was obtained,and the process yield of the casting was increased.

The defects of blowhole shrinkage and boiling often occurr in the production of cast steel bracket,and the process yield is low,the core cost is high.

Influence of Sprue Section on Technological Yield in Investment Casting;
