    摘要:

    通過不同紅外輻射源真空干燥荔枝試驗(yàn)以及干燥工藝品質(zhì)試驗(yàn),，表明果肉與輻射源光譜匹配顯著影響干燥速率，真空度,、輻射熱流密度的匹配影響干燥速率及干燥品質(zhì),；采用輻射源SZ,、輻射距離120mm、加熱/緩蘇時(shí)間15min/15min,、真空度0.02MPa的干燥工藝,，干燥速率與干果品質(zhì)綜合評(píng)價(jià)最優(yōu)。

    Abstract:

    Through the experiment of selective infrared radiation and vacuum drying and drying quality for litchi, it is found that the spectrum matching of litchi's flesh for radiation source has significant effect on drying rate, and the matching between vacuum and radiation heat flux has effect on drying rate and drying quality. The results show the optimum drying conditions are radiation source SZ, radiation distance 120mm, heating and tempering time 15min/15min and vacuum degree 0.02MPa respectively.
