    摘要:

    為解決氣體射流沖擊干燥機裝載量低,、噴嘴直徑與噴嘴出口形狀更換困難等問題,，設(shè)計了一種脈動式氣體射流沖擊干燥機,。該干燥機可根據(jù)不同物料調(diào)整風溫、風速,、料架轉(zhuǎn)速及噴嘴直徑與出口形狀,。干燥過程中物料受脈動高速熱氣流的沖擊，有利于物料內(nèi)部水分向外遷移,。以加工番茄為例進行了干燥機的性能驗證試驗,，結(jié)果表明：脈動式氣體射流沖擊干燥與氣體射流沖擊干燥相比裝載量和去水強度得到了較大的提高。

    Abstract:

    A pulsed air-impingement dryer was designed with large processing capacity, convenient to replace the size and shape of the nozzle exit compared to conventional air-impingement dryer. The machine could adjust air temperature, wind speed, rotary speed of materiel shelf, nozzle diameter and structure according to different materials properties. Material was received the pulsed impact of high-speed hot air, which contributed to outward migration of moisture within the material. Tomato was adopted to test the performance of pulsed air-impingement dryer. The results showed that the dehydration intensity and processing capacity of pulsed air-impingement dryer was improved than the conventional air-impingement dryer.
