塑料干燥機(jī)選擇注意事項(xiàng)

塑料干燥機(jī)選擇注意事項(xiàng)
以下是干燥裝置選型的一般原則，很難說(shuō)哪一項(xiàng)或哪幾項(xiàng)是*重要的，理想的選型必須根據(jù)自己的條件有所側(cè)重，有時(shí)折中是必要的。 
   塑料干燥機(jī)選擇注意事項(xiàng)1.不完全依賴過(guò)去的經(jīng)驗(yàn)，注重吸收新技術(shù)，多聽(tīng)專家的意見(jiàn)。
  塑料干燥機(jī)選擇注意事項(xiàng) 2.選型前*好能做出物料的干燥實(shí)驗(yàn)，深入了解類似物料已經(jīng)使用的干燥裝置（優(yōu)缺點(diǎn)），往往對(duì)恰當(dāng)選型有幫助。 
  塑料干燥機(jī)選擇注意事項(xiàng) 3.符合環(huán)保要求，工作條件好，**性高。  
   塑料干燥機(jī)選擇注意事項(xiàng)4.優(yōu)先選擇結(jié)構(gòu)簡(jiǎn)單、備品備件供應(yīng)充足、可靠性高、壽命長(zhǎng)的干燥裝置。     
   5.運(yùn)行成本低---設(shè)備折舊、耗能、人工費(fèi)、維修費(fèi)，備件費(fèi)...等運(yùn)行費(fèi)用要盡量低廉。 
   6.耗能低-------不同干燥方法耗能指標(biāo)不同，一般傳導(dǎo)式干燥的熱效率理論上可達(dá)100%，對(duì)流式干燥只能70%左右。
   7.節(jié)省投資-----完成同樣功能的干燥裝置，有時(shí)其造價(jià)相差懸殊，應(yīng)擇其低者選用。     
   8.干燥速率高---僅就干燥速率看，對(duì)流干燥時(shí)物料高度分散在熱空氣中，臨界含水率低，干燥速度快，而且同是對(duì)流干燥，干燥方法不同臨界含水率也不同，因而干燥速率也不同。 

   9.適用性-------干燥機(jī)首先必須能適用于特定物料，且滿足物料干燥的基本使用要求，包括能很好的處理物料（給進(jìn)、輸送、流態(tài)化、分散、傳熱、排出等），并能滿足處理量、脫水量、產(chǎn)品質(zhì)量等方面的基本要求。 

Plastic dryer selection considerations
The following is the general principle of drying equipment selection, it is difficult to say which one or which is the most important, the ideal selection must be based on their own conditions have focused, sometimes a compromise is necessary.
   Plastic dryer selection considerations 1. not entirely dependent on past experience, pay attention to absorb new technology, listen to the views of experts.
  Plastic Dryer Selection Notes 2. Before selection, it is advisable to make drying experiments of materials, and to understand the drying equipment (advantages and disadvantages) already used in similar materials, often help with proper selection.
  Plastic dryer selection considerations 3. Meet the environmental requirements, working conditions, and high security.
   Plastic Dryer Selection Considerations 4. Preferred Drying devices with simple structure, spare parts supply, high reliability, long life.
   5. Low operating costs --- equipment depreciation, energy consumption, labor costs, maintenance costs, spare parts costs ... and other operating costs should be as low as possible.
   6. Low energy consumption ------- different drying methods of different energy consumption indicators, the general conduction of thermal efficiency of dry up to 100%, convection drying can only about 70%.
   7. Save investment ----- to complete the same function of the drying device, and sometimes the cost difference between the poor, should choose the lower selection.
   8. Drying rate is high - only the drying rate, the convection drying material is highly dispersed in the hot air, the critical moisture content is low, the drying speed is fast, and the same is the convective drying, drying method different critical moisture content is different The drying rate is also different.
   9. Applicability ------- dryer must first be able to apply to specific materials, and to meet the basic requirements of the use of dry materials, including good processing materials (feeding, transport, fluidization, dispersion, transmission Heat, discharge, etc.), and to meet the processing capacity, dehydration, product quality and other aspects of the basic requirements.
