Importance of Yam Drying Technology in Yam Powder Processing

Yam drying technology is particularly important, for the quality of later products has a decisive factor, too high temperature will make yam scorch deterioration, too low temperature will cause inefficient dryer, today we will discuss the yam drying technology in yam powder processing importance.

yam powder can be used for washing and eating. The general processing procedures are: cleaning & mdash; peeling & mdash; slicing & mdash; drying & mdash; crushing & mdash; Blending & mdash; ripening & mdash; packaging and other processes. The most common yam dryer is hot air oven or drying room, of course, microwave dryer can also be considered.

yam should be sliced before drying, and then dried in different trays according to the size of slices. Generally speaking, the normal thickness of yam tablets, larger in the oven, need 80-100 degrees Celsius temperature drying for 8 hours to complete drying. For smaller ones, it may take 6 hours to dry at 70-80 degrees C, and for the smallest, it also needs 50-70 degrees C. If the size and thickness of the slices are not uniform, some of them will be scorched and others will not be thoroughly dried. Therefore, slice thickness should be the same as possible, when grading must be careful, and at the same time the poor quality of yam tablets removed, in order to avoid affecting the overall quality.

is crushed after drying. If the yam is fully dried, crushing is quite easy to do. The final requirement is 100-200 mesh, at least not less than 80 mesh to qualify. Subsequently, vegetable protein, taurine and other additives can be heated to prepare, and then matured and packaged by microwave equipment.
