The air absorbed by the fans is separated in and equably flows in the interior and outer canister, from to the heater and interior canister, the air is efficiently heat - treated, then the hot air influxes to and is balanced in because of the mixing by the heater, the hot airs temperature in has only little change, then it is separated completely from to ensure the balance - dryness of the colophony
由鼓風機吸入的空氣在處被分散，于內筒和外筒間均勻地流動，從處進入內筒和加熱管進行有效地熱交換。然後熱風在處匯集，在處無序混亂的熱內被均化。由於加熱箱熱風混合效果的作風，處的熱風溫度變化幅度很小，熱風經熱風排出口被完全均勻地分散開，從而保證了樹脂均勻乾燥。 -
Starting from the frozen food and refrigeration principles and using comparative analysis method, we get conclusions that in the blow - frozen device, the open - mode, cold - quantity reclaim, low - press, direct - cooling air, absorbing - heat air cycle have the most significant reductions in food freeze dry cost, food hygiene, devices delicate, organizating air stream, non - electrical heat, high efficiency and safe refrigeration etc. the cold - cumulating and dryness tin is the equipment which applys the store - release characteristic of cold - cumulating stuff, ensures the higher efficiency of open - mode cold - quantity reclaim low - press direct - cooling air, shoulders conveyance of the saturated and frozen air to frozen storeroom to reduce dry cost of food and dry the cycling air to ensure safe and reliable
從食品冷凍和製冷原理入手，用對比分析方式得到了在吹風式凍結裝置中，開式回冷低壓直接冷卻吸熱循環空氣製冷機具有最大幅度降低食品凍結乾耗、確保食品冷凍安全、系統簡單、凍結庫小巧、氣流易於組織、無電機熱量、效率較高和製冷安全等結論。蓄冷乾燥器是通過蓄冷材料的蓄?釋冷特性，來保證開式回冷低壓直接冷卻吸熱循環空氣製冷機具有較高的效率，同時蓄冷乾燥器還擔負著輸送飽和低溫空氣至凍結庫以降低食品凍結乾耗和乾燥循環空氣以確保整機安全可靠工作的主要設備。 -
Pertinent nasal problems include allergies to air - borne particles such as animal dander, and dryness of the nose because of a wood - burning stove
與鼻子相關的因素包括：對空氣傳播的微粒過敏，如動物的皮屑，還有因使用燒木炭的壁爐而使得鼻腔過干。 -
The paper first discussed in the numerous advantages of air - refrigeration machine which manufacture low temperature with the precondition of environment - protection. and expound the research and application what focus in exerting these advantages. introduce the principles of open - mode, cold - quantity reclaim, low - press, direct - cooling air, absorbing - heat air cycle and key components of the cold - cumulating and dryness tin
