Vacuum unit system used in corn drying _

corn is not easy to dry before storage. The moisture of corn stored will be higher, sometimes moisture content of 20% or more. This will bring difficulties to corn storage, so efforts to reduce the moisture of corn storage. This is especially important. According to the thermal characteristics of corn dry heat-sensitive materials and market requirement, consider its thermal stability and fracture characteristics of sensitivity, vacuum unit system of low temperature drying technology production test method, and the vacuum unit system applied to high temperature and moisture content of corn. The process and method are analyzed.

when the corn moisture content is 24%, vacuum unit system of high temperature water to keep the vacuum of the drying tower, the initial precipitation reached 10% ~ 15%. It guarantees the quality of corn color, aroma, taste, shape and nutrition ingredients, has advantages of good drying quality, rainfall, high output, low energy consumption, easy operation, high cost performance, etc.

high vacuum degree which in low temperature water evaporation, but high vacuum for heat conduction, this will influence on the material of the heating effect.

drying speed is the main index of reflecting the corn moisture migration velocity. On the premise of guarantee the quality of dry, improve the drying speed as much as possible.

for the processing of high moisture corn, generally USES the drying tower ( The dryer) Drying, manual drying, natural drying, mechanical ventilation, etc. Drying tower ( Drying machine) Drying can remove a lot of water, but it will reduce the quality of corn, resulting in a decline in the quality; Artificial drying natural drying will not cause thermal damage, but need a lot of artificial, this is equivalent to need to increase the purchase cost. Compared with the former two methods, mechanical ventilation and drying not only easy to use, but also need to lower cost, and also ensure the quality of the product.

1, on the basis of dry matter, wet maize storage close to dry corn starch and protein content, but research shows that the starch digestibility is higher.

2, reduce corn dry or dry, save manpower, save energy.

3, reduce the loss of corn and seed, because dry easy to drop, can increase the output of per unit area.

4, can receive early, avoid bad weather conditions, reduce the concentration of harvest caused by artificial and mechanical stress.

5, can choose a long growing season but high yield varieties, increase area yield through timely harvest.

6, corn cobs and eucalyptus leaves can be crushed and storage, according to need to increase the biomass, digestible fiber supplements, reduce the risk of starch of rumen acidosis caused by rapid decomposition.

vacuum unit system of low temperature drying technology drying provides the experience for the similar performance products, has a unique environmental protection and energy saving effect and innovation. Vacuum unit system in high moisture corn after the benefit, also by food, feed, food, chemical industry, environmental protection, and other related industries attaches great importance to, has a large market development value. Vacuum unit system energy saving of high efficiency and energy saving 30%, good quality, low noise, small vibration, environmental protection, stable structure.
